How to use and read the oil mark caliper

How to use vernier caliper: Vernier caliper is a length measurement tool that changes the rotary motion of the relative scale of the vernier ruler by the relative movement of the two measuring jaws, and reads the distance separated by the relative movement of the two measuring claws with the help of the corresponding scale of the ruler body scale and the vernier scale. Vernier caliper reading method:

The ruler index value is 1mm, the ruler body measurement range is determined according to the specifications (150mm, 200mm, 300mm), the vernier index value is, and the dial indication range is 1mm. Vernier caliper use and maintenance method: 1. The measuring surface must be wiped clean before use, and the measuring surface of the caliper and other transmission parts must be kept clean.

After measuring, the measuring claw should be closed casually to prevent dust, sand, metal chips and other objects from damaging the transmission part. 2. The measurement workpiece should be carried out under static conditions. When using, the measurement force should be appropriate, and calipers with micro-motion rollers should use micro-motion rollers.

3. The moving caliper frame should be stable, and the collision with the tail end or front end should be avoided by pulling quickly, and the impact and fall should be avoided to prevent the measuring claw from being damaged to the parts. 4. It is forbidden to place the caliper close to the magnetic field or on a magnetic object. If the caliper is found to be magnetic, it should be demagnetized in time before it can be used; 5. Non-professionals cannot disassemble the caliper transmission part, and the caliper must be calibrated regularly.

May I ask the landlord to ask the vernier caliper? The use of vernier calipers Japan Mitutoyo vernier calipers are more precise measuring tools, whether the use is reasonable, not only affects the accuracy and service life of the caliper itself, but also has a direct impact on the accuracy of the measurement results. 1) Before using the Japanese Mitutoyo vernier caliper, the caliper should be wiped clean, the caliper measuring claw should be closed, and the zero position and each part should be checked to see if the function is normal.

2) When measuring with Japanese Mitutoyo vernier caliper, the contact between the measuring claw and the workpiece should not be too loose or too tight. When measuring the inner diameter, first contact the main ruler measuring claw with the hole wall, and then gently swing and pull to find out the largest inner diameter position, and make the contact with the hole wall after reading. If measuring with a single-sided caliper, the jaw thickness value should be added to the reading.

3) When measuring the workpiece with a micro motion vernier caliper, the Japanese Mitutoyo vernier caliper should first tighten the micro motion frame fastening screw, and then turn the micro motion nut to make the vernier measuring claw gently contact the workpiece. If reading is not easy, you can also fix the frame and remove the caliper to take a reading. 4) When measuring with Mitutoyo vernier calipers, the manual push or pull force should not be too strong or too large, which will make the frame swing, resulting in inaccurate measurement results.

5) When measuring the Japanese Mitutoyo vernier caliper, it should be noted that the measured length and the jaw of the vernier caliper should not be skewed, once the skew measurement occurs, the measurement error will be significantly increased. 6) The Japanese Mitutoyo vernier caliper should be read under sufficient light, and the caliper should be in a horizontal position, and the line of sight of both eyes is perpendicular to the engraved surface of the caliper to reduce the reading error. This is what I saw on the Hikostar Industrial Surveying Mall, I hope it will be helpful to the landlord!

What is the use of vernier calipers and the method of reading.

Vernier calipers are made by means of two measuring jaws.

It is a vernier caliper, and the reading method is as follows:

1. Look at the total scale of the vernier ruler to determine the accuracy of the reed grinding (10 indexes, 20 indexes, and 50 indexes);

2. Read out the integer millimeter (x) of the main ruler on the left side of the zero scale mark of the vernier ruler;

3. Find out the position of the vernier ruler and the main ruler scale "opposite", and read out the number of small squares (n) from the alignment line to the zero scale line on the vernier ruler (do not estimate it);

4. Read out the measured value according to the reading formula.

Introduction to vernier calipers.

Vernier Calliper is a measuring tool for measuring length, inner and outer diameters, and depth. The vernier caliper consists of two parts: the main ruler and the vernier attached to the main ruler to slide the fight.

The main ruler is generally in millimeters, and the vernier has or 50 sub-grids, according to the different sub-grids, vernier calipers can be divided into ten-degree vernier calipers, twenty-degree vernier calipers, fifty-degree vernier calipers, etc., the vernier is 10 divisions of 9mm, 20 divisions of 19mm, 50 divisions of 49mm.

There are two sets of movable measuring jaws on the main ruler and vernier of vernier calipers, which are the inner measuring claw and the outer measuring claw, the inner measuring claw is usually used to measure the inner diameter, and the outer measuring claw is usually used to measure the length and outer diameter of the difference.

How to read this chart of the oil scale is as follows:

The integer part of the part size can be read on the main ruler engraved line on the left side of the vernier zero line, and the decimal part smaller than 1mm can be read out with the help of the vernier reading mechanism. Note the number of a line in front of the 0 tick mark of the vernier ruler of the master ruler. The figure below shows a vernier caliper with a 10-cell cursor, and each grid on the cursor is 1 10=.

Then see that the line of the second grid of the vernier coincides with the line on the main ruler, then the main ruler 13mm plus the vernier ruler 2*, then this caliper reading.

The following figure shows the vernier caliper with 20 grids, then each grid on the cursor is 1 20= Then see that the line of the second grid of the vernier coincides with the line on the main ruler, then the main ruler is 52mm plus the vernier ruler 7*, then this caliper reads the number of forest digging.

The figure below shows a vernier caliper with a 50-cell cursor, and each grid on the cursor is 1 50 =Then see that the line of the 2nd grid of the vernier coincides with the line on the main ruler, then the main ruler 3mm plus the vernier ruler 22*, then this caliper reading.

end precautions.

Note that the reading of the master ruler is the number of readings of a line in front of the 0 tick mark of the vernier scale.

Pay attention to distinguish the indexing of the vernier ruler, yes or no.

How to read the oil scale:

Vernier caliper readings are based on tick marks, which are between two values and read as an integer.

The value of the vernier ruler should be flush with the scale mark, and the measurement value should be read out according to the formula.

Generally speaking, if the scale is between two values, it is necessary to read the integer when reading, that is, the small number of millimeters.

Read the value referred to by the vernier, as well as the scale mark on the ruler, and the scale mark on the size, according to the nearest line value, destroy the source beam reading formula, that is, the measured value is equal to the main fiber ruler reading plus the vernier ruler reading the measured value.

It's a vernier caliper.

1. The marking principle and reading method of vernier caliper:

Take the example of a precision vernier caliper with graduated values, which consists of a main ruler with fixed feet and a secondary ruler (vernier) with movable feet. There are fixing screws on the sub-ruler.

The scale on the main ruler is in mm, and every 10 squares are marked with , etc., to indicate mm. The sub-ruler scale of this vernier caliper is to divide the length of the main ruler scale 49mm into 50 equal parts, that is, each grid is: mm.

Second, the reading is trapped or formula:

Measured value (l) = master ruler reading (x) + vernier reading (n accuracy) 10 index vernier caliper reading.

The minimum index on the ruler is 1mm, there are 10 equal divisions on the vernier, and the total length is 9mm on the main ruler, then each index on the vernier is, and the scale on the main ruler is different from a scale on the vernier scale.

Note: If the number after the decimal point is 0, it cannot be omitted, indicating precision.

That's called a vernier caliper. 0 is ...... for leadShoot the millimeter, and the opponent of the small ruler alignment is the millimeter Huai He Han. Generally accurate to the millimeter. In detail, B degree is possible.

The numbers are millimeters of accuracy, the manual cursor is millimeters of accuracy, and only o·o5 readings are read from the right end of the cursor! Hope.

The degree of the carving on the main ruler is in mm, and every 10 grids are marked with , Linglu 3, etc., to represent mm. The sub-ruler scale of this vernier caliper is to divide the length of the main ruler scale 49mm, divided into 50 equal differences in the yard parts, that is, each grid is: mm

Oil gauge caliper reading method:

When reading, the integer of millimeters is read on the ruler body based on the vernier zero tick mark, that is, the integer part in millimeters. Then see the alignment of the first few tick marks on the vernier with the tick marks of the ruler body, such as the 6th tick mark and the ruler body tick marks, then the decimal part of the tremor is millimeters (if there is no exactly aligned line, then take the closest aligned line for reading). If there is a zero error, the above result is subtracted from the zero error (the zero error is a negative eggplant, which is equivalent to adding a zero error of the same size), and the reading result is:

l = integer part + decimal part zero error.

To determine which tick mark on the sail cursor is aligned with the ruler body scale line, the following method can be used: select three adjacent lines, such as the line on the left is on the right of the corresponding line of the ruler body, and the line on the right side is on the left of the corresponding line of the ruler body, and the middle line can be regarded as aligned.

l= scale before alignment + alignment of the nth tick mark on the cursor with the tick mark of the ruler body * (multiplied) the graduation value.

If you need to average several measurements, you don't need to subtract the zero error each time, just subtract the zero error from the final result.

Vernier caliper is a measuring tool for measuring length, inner and outer diameters, and depth.

The vernier caliper consists of two parts: the main ruler and the vernier attached to the main ruler that can slide.

The main ruler is generally measured in millimeters, while the vernier has or 50 sub-grids, according to the different sub-grids, the vernier caliper can be divided into ten-degrees.

Vernier caliper, 20-degree vernier caliper, 50-degree grid vernier caliper, etc., the vernier is 9mm for 10 indexes, 19mm for 20 indexes, and 49mm for 50 indexes. Vernier calipers are found on the main ruler and vernier caliper.

The inner measuring jaw is usually used to measure the inner diameter, and the outer measuring jaw is usually used to measure the length and outer diameter.

The steps for reading oil scale calipers are as follows:Material preparation: Vernier caliper.

The operation step is complete

1. First of all, recognize the calipers.

2. The scale of the ruler body is the measured integer reading, and the vernier caliper is the decimal place reading of Zheng manuscript.

3. Then read the reading with the integer scale corresponding to the 0 digit of the vernier caliper.

4. Finally, read the calimal scale reading of the hand stove vernier at the position where the vernier card position and the card body index completely coincide.
