An anti-slip device for a needle guide rail

Abstract

The invention discloses an antiskid device for a roller guide rail. The anti-skid device for the roller guide rail comprises a guide rail mounting plate, a sliding block, a pair of first guide rails,a pair of second guide rails and two antiskid structures, a sliding block is arranged in a mounting groove portion on the guide rail mounting plate, the sliding block slides through a structure composed of the pair of first guide rails, the pair of second guide rails and a roller, a gear assembly is arranged between the guide rail mounting plate and the sliding block, and the sliding block drivesthe antiskid structures to work when moving. According to the antiskid device, that the product machining difficulty is reduced, the maintenance is more convenient, grinding residues between a gear and a rack which work for a long time cannot enter the guide rails, so that the service life of the guide rails is prolonged; the antiskid device is wide in adaptability, can be applied to various crossed guide rails, and is also more suitable for high-speed high-precision guide rails; and in the case of the antiskid device, the gear and the rack are meshed with each other, and the effect of balls is achieved, a quite good antiskid effect is achieved.

Description

technical field [0001] The invention relates to the application field of semiconductors, and more specifically relates to an anti-slip device for a needle guide rail which is different from the traditional meshing method. Background technique [0002] With the continuous development of semiconductor industry technology, the application fields are becoming wider and wider, and more and more high-end intelligent equipment needs to have higher precision and speed. This requires that the transmission standard parts we use on the equipment need better quality and performance to match them. The guide rail is the most critical core standard part in the transmission mechanism, and its importance is self-evident. In high-speed and high-acceleration Occasionally, it is also necessary to use guide rails with anti-skid gear functions. At present, high-precision meshing guide rails are mainly cross roller guide rails, cross ball guide rails and needle roller guide rails. The processing ...

This requires that the transmission standard parts we use on the equipment need better quality and performance to match them. The guide rail is the most critical core standard part in the transmission mechanism, and its importance is self-evident. In high-speed and high-acceleration Occasionally, it is also necessary to use guide rails with anti-skid gear functions. At present, high-precision meshing guide rails are mainly cross roller guide rails, cross ball guide rails and needle roller guide rails. The processing accuracy and requirements are extremely strict. Once the accuracy is slightly deviated, it is easy to cause mismatching of the guide rail gear meshing, jamming, and difficult adjustment. On the other hand, during long-term use of the built-in gear method, the worn-out grinding residue is not easy to discharge , It is also easy to cause related stuttering and unsmoothness; maintenance and installation adjustment are also inconvenient, which virtually affects the improvement of equipment accuracy and other performance, and greatly increases the cost of the enterprise
