Flexible self-adaptive mechanism for polisher

Abstract

The invention relates to a flexible self-adaptive mechanism for a polisher. The flexible self-adaptive mechanism comprises a main shaft and a tool shank arranged at the front end of the main shaft; the main shaft is sleeved and connected with through a bolt; the support frame comprises a cylinder sleeve and a bulge arranged at one end of the cylinder sleeve, and the outer wall of the main shaft is sleeved with the cylinder sleeve; the main shaft next to the side of the bulge is sleeved with the supporting seat; the supporting seat comprises a circular ring cake and a supporting seat cylinder sleeve; the main shaft is sleeved with the circular ring cake; the supporting seat cylinder sleeve is connected onto the outer ring of the circular ring cake, extends in the direction of the circular ring cake and covers the bulge of the support frame; a gap is formed between the circular ring cake of the supporting seat and the main shaft; a position on the inner wall of the cylinder sleeve of the supporting seat corresponding to position of the bulge of the support frame is arc-shaped; the circumferential surface of the bulge is arc-shaped; a pneumatic cylinder body is arranged in the supporting seat; eight groups of piston rod round pins and piston round pins are arranged in the pneumatic cylinder body; the piston rod round pins are pushed out in the direction of the bulge of the support frame. The flexible self-adaptive mechanism for the polisher has a benefit that the constant polishing contact force is guaranteed through keeping constant air pressure.

Description

[0001] technical field [0002] The invention relates to a grinding machine, in particular to a flexible adaptive mechanism of the grinding machine. [0003] Background technique [0004] The traditional robot automatic grinding process is to teach the trajectory of the robot according to the part model and the grinding area. During the grinding process, the robot runs according to a fixed trajectory for each workpiece. However, in actual operation, the size and flash burrs of each part are inconsistent, which will affect the quality of grinding, and will damage the tool when encountering large burrs. In order to improve the grinding yield, the stability of grinding quality, the efficiency and life of the tool, it is necessary to develop a mechanism that can adjust the grinding position and attitude of the tool in real time according to the size of the burr encountered, and cooperate with the robot to grind the parts.
