Transmission machinery Processing machinery as long as you feel you can use the lead screw.

There are too many things with lead screws. The lead screw is a trapezoidal thread, which is mainly used to transmit power, and the ball screw is generally used if the transmission accuracy is high.

The feed system of CNC machine tools is made of lead screws.

Machine tools, injection molding machines, conveyors, automatic doors, can be used in many occasions.

The function of the lead screw is to turn the rotation into movement, so the machine tools with the linear moving table basically use the lead screw.

Ordinary lathes. Ordinary milling machine.

Turning, milling, planing and other mechanical processing equipment are generally available.

Lead screw is a more accurate positioning method, which is generally applied to lathes, grinding machines, and milling machines. Use it as long as you feel you need it.

To quote a more complete answer:

The basic content of the fitter's work is:

Hand tools are used to perform various machining of workpieces on vices and platforms, and sometimes to repair equipment. The basic operations include marking, filing, sawing, chiseling, drilling, countersinking, reaming, reaming, tapping, threading, riveting, straightening, bending, grinding, measuring, assembling and commissioning, simple heat treatment, oil painting, etc.

The main task. It is mainly divided into the following processing parts, equipment maintenance, manufacturing and maintenance.

1. Processed parts.

Some machining that is not suitable or can not be solved by mechanical methods can be completed by fitters. Such as: marking in the process of parts processing, precision machining (such as scraping, frustration and making molds, etc.), inspection and repair, etc.

Assembly: The parts are assembled according to the technical requirements of the assembly of mechanical equipment, the components are assembled and matched, excavated and adjusted, inspected and tested, etc., so as to make them qualified mechanical equipment.

2. Equipment maintenance.

When the machinery fails during use, is damaged or the accuracy is reduced after long-term use, which affects the use, it should also be maintained and repaired by fitters.

3. Manufacture and repair of stools.

Manufacture and repair of all kinds of tools, fixtures, gauges, molds and all kinds of professional equipment.

The rotation of the motor at the end of the shaft is converted into linear motion by the relative rotation of the lead screw and nut. This enables high-precision displacement positioning. Conversely, it is also possible to change linear motion into rotary motion.

Lead screws include trapezoidal lead screws and ball screws.

Ball screws are mostly used in precision transmission occasions, such as CNC machine tools, CNC cutting machines, engraving machines, punching machines, etc.;

Equipment that requires high positioning accuracy, such as glass machinery, ceramic machinery, woodworking machinery, packaging machinery, circuit board packaging, etc.;

The ball screw has high transmission efficiency, is suitable for high-speed, frequent forward and reverse rotation of the transmission mechanism, and is widely used in machine tools, automobiles and aviation and other manufacturing industries.

The system using ball screw as the core functional component is highly integrated, simple, efficient, energy-saving, reliable and clean, which is the best choice to replace complex hydraulic systems.

With the development of industrial automation, the linear module composed of lead screws, sliders, linear guides, etc., has become more and more widely used.

Including industrial robots, manipulators and other fields have been widely used.

When the ball screw is used as the active body, the nut will be converted into linear motion according to the lead of the corresponding specification with the rotation angle of the screw, and the passive workpiece can be connected by the nut seat and the nut to achieve the corresponding linear motion.

Ball screws are ideal for converting rotary motion into linear motion, or for converting linear motion into rotary motion.

Ball screws are the most commonly used transmission elements in tool machinery and precision machinery, and their main function is to convert rotary motion into linear motion, or torque into axial repetitive force, and at the same time have the characteristics of high precision, reversibility and high efficiency. Due to their low frictional resistance, ball screws are widely used in a variety of industrial equipment and precision instruments.

The ball screw is composed of a screw, a nut, a steel ball, a pre-pressed sheet, a reverser, and a dust preventer. Its function is to convert the rotational motion into linear motion, which is a further extension and development of the Eckham screw, and the significance of this development is to change the bearing from a sliding action to a rolling action.

The tool is fixed, so that the tool rotates and moves in parallel in one direction, and when the chip axis rotates the workpiece, the tool moves in a straight line relative to the workpiece.

The lead screw moves in parallel with the linear motion of the workpiece, and rotates and moves in parallel with the fixed axis relative to the ground.

I'm afraid the lead screw can't do it. With linear motors, I think it's possible. Don't know what your accuracy requirements are?

I'm having the same issue, but my platform isn't as heavy as yours! Only a dozen kilograms. The speed is as ...... as yours

Summary. Lead screw straightening method: 1. Under normal circumstances, for the straightening of the lead screw, the way of manual straightening can be adopted first, and it can be directly placed on the U-shaped iron block, and then the flat shovel that has been opened and ground into a circle is placed in the convex position of the lead screw, and then the sledgehammer is used to strike it, and the dial gauge is used to straighten, this step needs to be repeated many times.

2. Secondly, if the lead screw needs to be bent as a whole, it needs to be straightened with the help of a press. It is also necessary to place the lead screw on the U-shaped iron block, place the round fetus under the lead screw, and observe the straightening effect by the naked eye, and use the dial gauge to align it, which also needs to be repeated many times. 3. If the trapezoidal lead screw is bent locally, the manual straightening method is ideal, and the overall straightening is the same, and the manual is to use a sledgehammer to repeatedly knock on the bending position of the lead screw to achieve the ideal straightening effect.

Hope it helps.

Secondly, if the lead screw needs to be bent and lifted as a whole, it needs to be straightened with the help of a press.

In the same way, the lead screw needs to be placed on the U-shaped iron block, and the round mold is placed under the lead screw, and the straightening effect can be observed by the naked eye, and the dial gauge can be used to align it, which also needs to be repeated many times. 3. If the trapezoidal lead screw is partially bent, the manual straightening method is more reasonable to destroy the old thoughts, the way is the same as the overall straightening, and the manual is to use a sledgehammer to repeatedly knock on the bending position of the lead screw to achieve the ideal straightening effect. Hope it helps.

How to teach straight if it's not a trapezoidal screw.

Two U-shaped pieces of iron are attached to the base, after which the vertical crane with a round shape is placed on top of the trapezoidal screw and corrected using a table of percentages. The straightening method of the lead screw can also be straightened by hand, the screw rod is directly placed on the U-shaped iron block, the previous opening has been good, the sledgehammer is used to beat it, the percentage table is used to align, and the straightening can be achieved by repeating the process many times.

Summary. There are several ways to teach the lead screw in the mechanical manufacturing process. There are three kinds.

1. If you need to straighten the trapezoidal lead screw, then the best way to straighten it is to do it manually, place the trapezoidal lead screw directly on the U-shaped iron block, place the flat shovel that has been opened before, or has been ground into a circle, directly place it in the most protruding position of the trapezoidal lead screw, use a sledgehammer to beat it, use the percentage table to align, and then repeat the process many times to achieve the effect of straightening. 2. When you need to bend the trapezoidal screw as a whole, it is recommended that you can use a press to complete the straightening, and at the same time put the trapezoidal screw directly on the two U-shaped iron blocks, and then put the circular fetus on the trapezoidal screw, which can be observed with the naked eye and corrected by using the percentage table. 3. The trapezoidal lead screw does need to be straightened, if there is an overall or individual bending, or when the bending is of different sizes, you can choose to use manual straightening according to the actual situation, or choose a press to straighten.

There are two main types of rolling methods: horizontal rolling method and oblique rolling method. When rolling the screw by the transverse rolling method, the axis of the roll and the axis of the workpiece are parallel to each other, and the manufacturing methods of the ball screw are mainly two: rolling and grinding, the former is also called rolling manufacturing or transformation, which is generally represented by F.

Li Ku The latter is also called grinding manufacturing. It is generally denoted by g. At present, the highest accuracy that can be achieved by the rolling method is C5 level, and grinding can produce products with higher precision.

There are many types of lead screws, including metric screw threads, inch screw threads, metric screw threads, trapezoidal screw threads, triangular screw threads, sawtooth screw threads, square screw screw threads, etc., and their classification mainly includes use classification, tooth type classification, type classification, pitch classification, unit classification and the inventor's surname or country of invention classification.

What are the lead screws.

There are many types of screw rods, such as metric screw threads, inch screw threads, metric screw threads, trapezoidal screw threads, triangular screw threads, sawtooth screw threads, square tooth screw threads, etc., and according to different classification methods, the screw threads are also different.

According to the classification of use, it can be divided into fastening screw thread, sealing screw thread, pipe screw thread, transmission screw thread, ordinary screw thread, special screw thread, etc. According to the tooth type classification method, it can be divided into trapezoidal screw thread, zigzag screw thread, rectangular screw thread, triangular screw thread, short screw thread, 60 screw and 55 screw thread.

According to its type, it can be divided into transition screw thread, interference screw thread, gap screw screw thread, etc., according to the pitch classification method, it can be divided into coarse tooth screw thread, fine land screw screw thread, etc., and can be divided into imperial screw thread and metric screw thread through unit classification, and can be divided into Wyeth screw thread and American screw screw thread according to the inventor's surname or country of invention.

Influence of the working environment of the bed such as temperature, humidity, dust, vibration and so on. Wire cutting machine tools for precision machining generally use 6-level precision lead screws. If it is matched with the nut, there is a gap in the axial direction and an idle stroke in the reverse, which will bring transmission error.

The matching gap is too small, the screw transmission is difficult, and the transmission motor is overloaded, which may cause loss of step and cause error; If the gap is too large, although the screw rotates flexibly, the reverse idle stroke is large, which also causes errors. The assembly accuracy of the lead screw and the nut has a great influence on the moving accuracy of the coordinate workbench, when the three lines of the lead screw and the nut are not straight, the moving distance of the workbench will have an error, especially when the lead screw rotates a fraction of a turn, the error is larger, up to about millimeters. The lead screw is not parallel to the guide rail, which will not only reduce the amount of movement, but also bring the problem that the three wires are not straight.

Even if the lead screw is aligned with the nut at one point of the table, it will not be aligned when it is moved to another point. When the three lines are not straight, the cut arc will produce surface ripples. These have a direct impact on machining accuracy.

The gap between the transmission gear pair and the key and other transmission chains will also cause the instability of the amount of movement, and also affect the machining accuracy. The verticality of the longitudinal and transverse carriage guide rails also affects the machining accuracy, especially the ovality.

Components of the lead screw transmission mechanism of ordinary machine tools: mainly composed of lead screw, nut, ball and raceway (ball returner), nut seat, etc.

It works by machining arc-shaped spiral grooves on the lead screw and nut, which when they are packed together to form a spiral raceway and fill the raceway with balls. The balls roll along the raceway and go through the return tube in a circular motion.

The two return bead tubes also play the role of blocking beads to prevent the balls from falling out along the raceway.

The nut is connected with the slide box, and when the lead screw rotates, the nut moves left and right with the slide box.
