Abstract

The invention discloses a planetary motion grinding device, and belongs to the technical field of manufacturing of precision machinery. The invention aims to overcome the defects of the existing mechanical grinding technology, and provide the grinding device capable of removing quantitative materials, stably running, and removing the function stability. The grinding device comprises an interface panel, a revolution mechanism, an eccentric adjusting mechanism, a main seat body, a translation keeping mechanism, a swing mechanism, a rotating mechanism, a pressure applying mechanism and a grinding disc mechanism; the revolution mechanism provides revolution movement; the rotating mechanism provides rotation movement and axial free flotation of a grinding disc; the eccentric adjusting mechanism realizes adjustment on the revolution radius; the translation keeping mechanism ensures that the main seat body, the swing mechanism, the rotating mechanism, the pressure applying mechanism and the grinding disc mechanism stably move in the revolution movement, and assists a support device in gravity; the pressure applying mechanism is used for applying grinding pressure; and the grinding disc mechanism can ensure that the grinding disc can incline at a small angle in any direction.

Description

technical field

[0001] The invention belongs to the technical field of precision machinery manufacturing, and in particular relates to a grinding device used for mechanical grinding and obtaining high machining accuracy. Background technique

[0002] In mechanical processing, grinding technology has developed rapidly. From traditional manual grinding, various types of grinding machines have been developed, which have replaced manual labor to a certain extent and met the grinding requirements of small and medium-sized parts. Like manual grinding, it is qualitative grinding. For large and heavy parts and large planes, the finishing of such parts still adopts the traditional processing idea. After the rough machining and semi-finishing of large-scale equipment, the finishing is completed by manual local repairing. Because it is a qualitative correction , there are blindness and human factors, the accuracy is difficult to improve. Quantitative grinding technology has been well...
