Embodiment

[0019] refer to figure 1 , a method for 3D concave surface polishing, using the rotation and reciprocating motion of the polishing hair wheel, and the rotation and revolution motion of the workpiece to effectively improve the polishing track of the 3D concave arc surface workpiece.

[0020] In this embodiment, the polishing hair wheel 1 drives the polishing hair wheel through an independent motor and a belt transmission mechanism to realize the rotation of the polishing hair wheel, and drives the cam to perform an eccentric circular motion through another motor and a belt transmission mechanism, and then drives the connecting assembly and the polishing hair The grinding wheel realizes the reciprocating motion of the polishing wheel; the workpiece is fixed by the vacuum adsorption of the tooling in the cutting disc 2, and rotates together with the cutting disc 2. The meshing transmission realizes the revolution.

[0021] In this embodiment, the connection assembly includes a c...

Abstract

A method for polishing a 3D concave surface uses the rotation and reciprocating motion of a polishing wheel and the rotation and revolution motion of a workpiece to effectively improve the polishing trajectory of a 3D concave arc workpiece. Through the profiling polishing of the 3D concave arc surface, the uniform speed sweeping of the polishing wheel on the 3D concave workpiece can be controlled, and the demand for the adjustable pressure of the polishing wheel and the workpiece can be realized, which not only improves the concave shape. The efficiency of curved surface polishing also improves the yield of polished products.

Description

technical field [0001] The invention relates to a method for 3D concave surface polishing. Background technique [0002] At present, the polishing method of conventional polishing machines is to use one upper plate or several small upper plates as the polishing plate, and the lower plate as the loading plate, load and fix the tooling, the workpiece is fixed in the tooling, and the workpiece rotates with the lower plate. The polishing disc is reversely rotated by external pressure to achieve polishing of the workpiece. [0003] When this method is applied to the polishing of a workpiece with a concave curved surface, it is prone to the phenomenon that the polishing is not in place or the polishing accuracy cannot meet the requirements, resulting in prolonged polishing of the workpiece and unstable product yield. Contents of the invention [0004] The technical problem to be solved by the present invention is to provide a 3D concave polishing method that can avoid the pheno...
