Polishing machine with 3D hook face

Abstract

The invention discloses a polishing machine with a 3D hook face. The polishing machine comprises a rack, a jig assembly and a polishing wheel assembly. The rack comprises an inner frame and an outer frame. The jig assembly is fixed on the inner frame, and comprises a plurality of workpiece disks and a first driving mechanism used for driving the workpiece disks to move in a reciprocating mode. Containing tanks used for containing workpieces are formed in the workpiece disks. The polishing wheel assembly is rotatably matched with the outer frame, and comprises a mounting rack matched with the outer frame in a rotating mode, and a plurality of polishing wheels used for polishing the workpieces are arranged on the mounting rack. According to the polishing machine with the 3D hook face, the workpieces move in a reciprocating mode relative to the polishing wheels, so that multi-degree abrasion of the polishing wheels to the edges of the concave surfaces of the workpieces is reduced, and the multi-degree abrasion suffered by the edges of the concave surfaces of the workpieces is avoided through the height difference between tank ports and tank bottoms of the containing tanks.

Description

technical field [0001] The invention relates to the technical field of polishing equipment, in particular to a 3D curved surface polishing machine. Background technique [0002] The polishing machine is a kind of equipment for polishing the surface of the workpiece. It is widely used in the polishing and grinding of 2.5D / 3D curved glass and other hard and brittle materials. [0003] Most of the existing polishing machines for 2.5D / 3D curved glass are 3D curved surface polishing machines. By placing the workpiece on the lower disc, pressing down the upper polishing disc, and then rotating the upper polishing disc or (lower disc) to the workpiece for polishing. The polishing machine with 3D curved surface can polish multiple workpieces with high efficiency. However, when polishing a workpiece with a 2.5D / 3D concave surface, the upwardly curved edge of the workpiece bears greater pressure, that is, the polishing force of the polishing wheel on the edge of the workpiece is gre...

AI Technical Summary

Problems solved by technology

However, when polishing a workpiece with a 2.5D / 3D concave surface, the upwardly curved edge of the workpiece bears greater pressure, that is, the polishing force of the polishing wheel on the edge of the workpiece is greater, resulting in damage to the edge of the workpiece Excessive grinding

As a result, the concave surface of the workpiece cannot be perfectly fitted with other parts during assembly, forming a large gap
