Door handle grinding and polishing clamp with anti-winding function for robot

Abstract

A door handle grinding and polishing clamp with an anti-winding function for a robot comprises a robot fifth shaft fixing mechanism, an infinite rotating mechanism, a door handle clamp and a door handle workpiece; the infinite rotating mechanism and the robot fifth shaft fixing mechanism are connected in a matched mode; the door handle clamp and the infinite rotating mechanism are connected in a matched mode; the door handle clamp at least comprises a robot connection flange, a tensioning air cylinder, a tensioning center and a tensioning clamping piece; the robot connection flange and the infinite rotating mechanism are connected in a matched mode; the tensioning air cylinder is arranged on the robot connection flange and is in driving connection with the tensioning center; the tensioningcenter drives the tensioning clamping piece to clamp or loosen the door handle workpiece through the tensioning air cylinder; the infinite rotating mechanism at least comprises a rotating air distribution shaft and a fixed shell; the rotating air distribution shaft is rotationally inserted in the fixed shell, an air guiding block is arranged on the lower portion of the rotating air distribution shaft, and the air guiding block is connected with the tensioning air cylinder in a matched mode; and the rotating air distribution shaft, the air guiding block and the tensioning air cylinder rotate freely relative to the fixed shell. Practicability is high.

Description

technical field [0001] The invention relates to a door handle robot grinding and polishing jig with anti-winding. Background technique [0002] The existing door handle grinding and polishing applications are mainly manual, and in a small number of automatic applications, the air pipe is easy to be entangled with the fixture. In order to avoid winding, the rotation angle of the sixth axis of the robot must not exceed 200°, and the rotation path must be positive and negative to meet the requirements. At the same time, the sixth axis of the robot needs to return to its original position after each grinding, resulting in unnecessary beat waste; at the same time, the fixture When clamping the outside of the door handle, because the outer surface of the workpiece is covered, the outer surface of the workpiece cannot be polished and covered at one time during grinding. User needs. Therefore, further improvement is necessary. Contents of the invention [0003] The object of th...
