AI Technical Summary

Problems solved by technology

[0004] (1) The support platform is fixed on the base of the grinding machine. In order to ensure the machining accuracy, it is necessary to keep the base level at all times so as not to affect the machining accuracy. However, the level adjustment of the traditional base is very troublesome, and its level cannot be precisely controlled; With the rotation of the grinding wheel, the whole equipment is in a state of constant vibration, which requires high stability of the base, while the structural stability of the traditional base is poor. In the case of long-term vibration, the service life is short, and the connection of various components Screws are easy to loosen and produce small displacement, which will affect the machining accuracy

[0005] (2) During the processing, the supporting platform can move along the X and Y directions to adjust the position of the rotary file. However, the traditional supporting platform cannot accurately control the moving position, and the operation is not stable enough, which affects the machining accuracy.

[0006] (3) The transmission mechanism of the traditional A-axis structure adopts a worm gear, which has a small transmission ratio, low rotation efficiency, small load-carrying capacity, and large return clearance, which makes the precision of the structure low; and the connection between the chuck and the tie rod is not tight. Usually the collet is fastened to the tie rod. During production and use, the collet is easy to fall off and is not suitable for long-term connected processed products.

[0007] (4) The traditional swing arm structure, either the cost is too high, the structure is complicated, or the precision is too low, the efficiency is not high, and the operation requirements under high precision cannot be guaranteed for a long time; The gap between them is large, resulting in low accuracy

In the process of operation, manual control is usually required, resulting in not only high labor intensity for workers, but also slow grinding speed and low efficiency, which is not conducive to mass production; the product consistency at the production site is poor, which is easy to affect subsequent processing, thus affecting entire production line
