Problems solved by technology

In the semiconductor automation production line, the transportation, installation and commissioning, processing, etc. of the equipment often need to be adjusted by the adjustment device, so that the automation equipment has higher precision working performance. The design of rack and pinion is designed according to no backlash, but due to errors in processing and installation, the deviation of backlash when the gear and the rack are meshed and driven is often not guaranteed to be within the range of use requirements, and the gap between the rack and the gear when the rack is driven The backlash deviation between them will affect the stability of the transmission or the accuracy of the position control, and also affect the production efficiency and production quality of the product

Embodiment Construction

[0016] In order to describe the technical content and structural features of the present invention in detail, the following will be further described in conjunction with the embodiments and accompanying drawings, wherein the same reference numerals in different drawings represent the same components. As mentioned above, the present invention discloses a rack drive backlash adjustment device, which is suitable for pairing with gears, and is used to automatically adjust the backlash between the rack and pinion, and uses the elastic properties of the elastic element to push the rack, The adjustment hole on the rack has an adjustable distance relative to the adjustment screw, so that the mutual force between the gear and the rack can achieve a dynamic balance, and the center distance of the rack and pinion can be automatically adjusted, so that the rack and the gear are always connected when they are in transmission. Keep it in a tight state, so as to achieve the purpose of automat...

Abstract

The invention discloses a gear rack drive backlash adjustment device, which is suitable for pairing with gears and includes a rack and a bracket. The rack is installed on the bracket and engages with the gear. It has a mounting surface and a supporting surface perpendicular to each other. The mounting surface is horizontal. There are screw holes on the mounting surface. Adjustment holes corresponding to the screw holes are provided on the rack. One end of an elastic element is fixed on the supporting surface. The other end is in conflict with the rack. One end of an adjusting screw engages with the screw hole, and the other end passes through the adjusting hole and can slide horizontally in the adjusting hole. When the gear meshes with the rack, the adjusting hole slides along the adjusting screw. The elastic performance of the elastic element is used to realize the adjustable distance between the adjustment hole and the adjustment screw, so that the mutual force between the gear and the rack can reach a dynamic balance, and the center distance of the rack and pinion can be automatically adjusted to make the rack close to the gear. meshing to achieve the purpose of adjusting the backlash and make the transmission more accurate and stable.

Description

technical field [0001] The invention relates to an adjusting device, more particularly to a rack drive backlash adjusting device. Background technique [0002] With the development of industrial technology and the improvement of industrial automation level, the requirements for industrial equipment, processing technology and product quality are also getting higher and higher. In the semiconductor automation production line, the transportation, installation and commissioning, processing, etc. of the equipment often need to be adjusted by the adjustment device, so that the automation equipment has higher precision working performance. The design of rack and pinion is designed according to no backlash, but due to errors in processing and installation, the backlash deviation when the gear and the rack are meshed and driven is often not guaranteed to be within the range of use requirements, and the gap between the rack and the gear when the rack is driven The backlash deviation ...
