Choosing the right two-dimensional image measuring instrument and three-dimensional measuring instrument is crucial to ensure measurement accuracy and improve work efficiency. When purchasing, it is recommended to consult the best business provider in detail to understand the product performance and service details.

Overview: In general, the quality of domestic two-dimensional imagers is uneven or even very different. If you want to buy a two-dimensional measuring instrument, it is recommended that you:

First of all, it is to choose a regular big brand manufacturer, so that the quality of the image measuring instrument has a preliminary guarantee. In general, the quality of domestic two-dimensional imagers is uneven or even very different. If you want to buy a two-dimensional measuring instrument, it is recommended that you:

First of all, it is to choose a regular big brand manufacturer, so that the quality of the image measuring instrument has a preliminary guarantee.

Secondly, buy an imager to see if its main accessories are brand manufacturers (CCD lens rail) These have an impact on the accuracy and performance of the second element, of course, it is best to go to the scene to see the instrument yourself:

1. See whether the image of the two-dimensional image measuring instrument is clear and whether there are snowflake spots;

Second, see whether the transmission of the second element is smooth;

Third, the marble structure of the image measuring instrument is definitely much better than that of cast iron or cast aluminum, after all, marble has been buried in the ground for tens of millions of years, and it is not easy to heat deform and not easy to scratch than cast iron.

In addition, the hardware accessories and software of the image measuring instrument are of course better to see whether they are developed by themselves, and it is better to obtain the original patent by themselves, at least it shows that the company's technical strength is still good.

The two-dimensional measuring instrument is also called: flash measuring instrument, automatic image measuring instrument, one-button image measuring instrument, etc.

It is characterized by the ability to quickly measure the dimensions of small workpieces, such as center line, arc, peak circle, fitting line, fitting circle, tangent line, pitch distance, angle, slot, thread, chamfer, fillet and other parameters, which is based on two-dimensional measurement, and is generally speaking, photographic measurement.

Structural composition. As the name suggests, the three-dimensional measuring instrument is one more dimension than the two-dimensional measurement, and can measure the dimensional parameters of the three-dimension.

But just measure the side of the workpiece to be measured, for example, you want to measure a bearing, put the bearing flat on the measuring platform, the lens of the three-dimensional measuring instrument is facing the top of the bearing to take pictures and measure the surface is two-dimensional measurement, and then there will be a stylus or probe on the side of the measuring platform to measure the side size of the bearing, and finally the measurement software calculates that the three-dimensional size parameters of the bearing can be obtained.

Most of the three-dimensional machine structures use precision granite as a platform, and the better machines will use granite above level 00. The majority of the triaxial structure is made of granite, some models use aluminum alloy or cast iron, and the higher models use carbon, ceramic or other composite materials. The common appearance structure is gantry type (or mobile bridge type), and other more common ones are unilateral bridge type (or L bridge type), bilateral bridge type, cantilever type, etc.

For "entertainment and leisure - animation", the second dimension refers to the illusory world, such as the Internet. Three-dimensional measurement refers to the reality of the world. The following is an explanation of the two-dimensional and three-dimensional machinery industry.

The two-dimensional is simply to be able to carry out two-dimensional measurement, can not do three-dimensional measurement, like the size of the space for it can do nothing, mostly for the image measuring instrument, that is, optical non-contact measurement, can be the workpiece from several times to hundreds of times of magnification measurement, for some soft, fine, small workpiece, there is no comparable advantage.

The three-dimensional is a three-dimensional measuring instrument (x, y, z), which can be used for spatial measurement, mostly with probe contact measurement, especially for some curved surfaces and special-shaped parts, which can reflect its powerful functions, and for large parts, such as vehicle frame measurement.

At present, the development trend of measuring instruments has been diversified, such as two-dimensional can also add probes for three-dimensional measurement, three-dimensional can also add image function for non-contact measurement, etc.

The two-dimensional is for plane measurement, three-dimensional measuring instrument, mainly refers to a kind of instrument that measures through three-dimensional points, and there are also three-dimensional coordinates on the market, three-dimensional coordinate measuring machine, three-dimensional coordinate measuring instrument, three-dimensional.

Yixin two-dimensional measuring instrument.

According to the introduction of China Instrument Supermarket**, the secondary measuring instrument can be divided into different categories according to different methods, and the most common is to classify it according to the operation mode of the secondary element measuring instrument, which is mainly divided into two types: manual image measuring instrument and automatic image measuring instrument. Manual image measuring instrument, in the development of the imager, belongs to an important stage of the transition period, it is through the handle or joystick to control the operation of the two-dimensional detector, to complete the operation of the workpiece, such as Zhitai MUMA200 all-aluminum alloy optical image measuring instrument.

Three-dimensional measuring instrument, also known as three-dimensional measuring machine, three-dimensional detector, three-dimensional image measuring instrument, etc., referred to as three-dimensional coordinates, refers to an instrument that can express the measurement ability of geometry, length and circumferential indexing within the spatial range of a hexahedron, also known as three-dimensional coordinate measuring instrument or three-dimensional. As a high-precision measuring instrument, the reason why the three-dimensional measuring machine can accurately measure the three-dimensional parameters of the measured object is inseparable from the relevant accessories of the three cosms, and it is precisely because of the existence of these accessories that the three coordinate measuring machines can have high measurement accuracy.

There are basically two methods for angle measurement of the two-dimensional measuring instrument, one is the tangent method, and the other is the point calculation method. The tangent method is convenient and simple to operate, but the measurement precision reading is low, which is suitable for rapid batch detection.

All geometric elements are somewhat composed, including the basic elements of lines, curves, and arcs. A two-dimensional plane angle consists of two straight lines, a basic geometric element, and a straight line is made up of an infinite number of points. Therefore, whether the angle measurement is accurate or not, the collection point is the most critical.

Definition of Quadratic Measuring Instrument:It is used to measure the size of two-dimensional planes, and is widely used in a variety of different precision industries. It is mainly used in calipers, angle rulers are difficult to measure or can not be measured at all, but play an important role in the assembly of parts size, angle, etc., such as silicone, circuit board creepage distance, electrical clearance, control panel light holes, some sizes of plastic parts, etc., can also be used for the analysis of some parts and components for the analysis of defective causes.

Because the image measuring instrument is the image obtained by using surface light or contour light to illuminate the parts, the measurement of the parts needs to take points, and not all parts are measured by the two-dimensional measuring instrument is the most precise, and the best method and the most effective way can be the most accurate to measure the size of the parts.

The current ACG measuring instruments are all intelligent operations, and the requirements for the operators are not high, and they will be fool-proof operations at a glance. Put the workpiece to be measured on the measuring platform, and then select the part to be measured by selecting the point, line, circle and other boxes on the measurement software, and then click to measure, the software will automatically calculate the measurement result parameters, and then save the measurement as a template, when the same workpiece is measured in batches, a plurality of workpieces are directly placed on the measurement platform, and a single workpiece should not be attached or overlapped with other workpieces as much as possible, so as not to affect the measurement data, and then press the measurement button, and the batch measurement results can be obtained in two or three secondsThe measurement results can be saved as word, excel for the printer to print the report.

The instrument is generally equipped with a manual, if in Chongqing, we can come to the training. The two-dimensional element can measure a single element such as a garden, line point, etc., or it can build a virtual element through the measured elements to build a plane coordinate system.

The use of the old two-dimensional measuring instrument is a bit complicated, the operator needs to locate and find the origin, some even need to be programmed, the measurement of an object program is complicated, the measurement speed is slow and time-consuming, now there is a new version of the VX3000 flash measuring instrument, no need to locate and find the origin, only need to place the measurement object and press the measurement button, the instrument will automatically locate and identify, automatically match the template, truly achieve one-key measurement, and can automatically issue a measurement report for the operator to check and print.

The differences between two-dimensional and three-dimensional measuring instruments are: different references, different functions, different uses, etc.

1. The reference is different.

1) Two-dimensional coordinate measuring instrument: used to measure the size of the wheel of products and molds, the measurement elements include position, concentricity, straightness, contour, roundness and the size related to the datum.

2) Three-coordinate measuring instrument: all three axes have air source brake switch and micro-motion device, which can realize single-axis precision transmission and adopt high-performance data acquisition system.

2. The functions are different.

1) Quadratic coordinate measuring instrument: It can measure any geometric size on the plane, including diameter, radius, length, angle, width, height, depth, point-to-point distance, point-to-line distance, center distance, etc. It has the function of taking pictures of parts, which can be compared more intuitively.

2) Coordinate measuring instrument: high-performance DC DC servo motor, flexible synchronous toothed belt transmission device, each axis is limited and electronically controlled, the transmission is faster, and the movement performance is better.

3. Different uses.

1) Two-dimensional coordinate measuring instrument: used to measure two-dimensional plane size, widely used in a variety of different precision industries. It is mainly used in the calipers and angle rulers that are difficult to measure or cannot be measured at all, but play an important role in the assembly of parts size, angle, etc., such as silicone, the creepage distance of the circuit board, the electrical clearance, the light hole of the control panel, some sizes of plastic parts, etc.

2) Three-axis measuring instrument: The three-axis adopts natural high-precision granite guide rail, which ensures that the whole has the same thermodynamic performance and avoids the machine accuracy error caused by the different thermal expansion coefficients of the three-axis material.

The principle of the three-dimensional measuring instrument:

The measured object is placed in the three-dimensional measurement space, and the coordinate position of each measured orange point on the measured object can be obtained, and the geometric size, shape and position of the measured object are calculated according to the spatial coordinate values of these points. <>

VX3000 series two-dimensional image measuring instrument mainly measures the two-dimensional size parameters of mechanical parts, hardware accessories, electronic components, medical equipment, plastic parts, PCB boards, sealing rings, bearings, etc., with fast measurement speed and high efficiency, which is a necessary measurement method for many factories and enterprises.

The three-dimensional image measuring instrument is based on the two-dimensional size measurement of length and width, and has an additional function of measuring height.

The difference between two-dimensional dimensional and three-dimensional.

The two-dimensional and three-dimensional are widely used in the quality inspection room of the research institute of molds, medical equipment, electronics, auto parts, mobile phone accessories, precision hardware, aviation industry, and research institutes. First of all, let's figure out what is two-dimensional? What is Dimensional?

What is Three-Dimensional?

The two-dimensional image mentioned here is actually the two-dimensional imager, or the image measuring instrument, the two-dimensional projector, the imager, etc., in fact, it is the image measuring instrument that is widely used at present, that is, with computer software, CCD and other measuring instruments. In fact, the projector tool microscope we used before is also a kind of two-dimensional dimension, as the name suggests, the two-dimensional is mainly to measure two-dimensional dimensions, such as length, width, height, hole spacing, spacing, pin spacing, thickness, arc, diameter, radius, groove, angle, R angle, etc., that is, the size of the XY direction.

The dimension here also refers to the image measuring instrument, but many manual imagers on the market do not have a grating ruler on the Z-axis, that is, there is no accuracy, can not measure the height and thickness, etc., the Z-axis of the company's first-class TZTEK imager is not only accurate, the Z-axis also has an automatic focus function, which can assist in measuring the height and thickness of the product The use of self-developed software can realize the Z-axis automatic focus, and the fictional three-dimensional space realizes the high-precision measurement function of the inner cone angle, which is a real dimension.

The three-dimensional dimension mentioned here is what we usually call the three-coordinate measuring machine and the three-coordinate measuring instrument, which is the measurement of the three-dimensional space size of the product, which belongs to contact measurement. At present, machinery, electronics, molds, injection molding, hardware, rubber, low-voltage electrical appliances, magnetic materials, precision hardware, precision stamping, connectors, connectors, terminals, mobile phones, home appliances, computers (computers), LCD TVs (LCDs), printed circuit boards (circuit boards, PCB), automobiles, medical equipment, clocks, instrumentation and other industries in addition to some measuring tools such as micrometers, digital calipers, dial gauges, testing instruments such as hardness testers, ultrasonic thickness gauges, metallographic microscopes, profilometers, roughness meters, etc., More sizes are measured using non-contact image measuring instruments and contact coordinate measuring machines.
