Water-cooling single-side polishing machine

Abstract

The water-cooling single-face polishing machine comprises an upper grinding disc device and a lower grinding disc device, the upper grinding disc device comprises an upper base, a lifting seat, an upper grinding disc mechanism and a rotary driving mechanism, a sliding rail is vertically arranged on the upper base, a sliding block is arranged on the sliding rail, and the lifting seat is arranged on the sliding block; a lifting driving mechanism for driving the lifting seat to move up and down is arranged on the upper base; the upper millstone mechanism comprises a jig disc, a base disc, a self-aligning bearing, a flange disc, a rotating shaft pipe, a rotating connector A and an air pipe. The lower millstone device comprises an inner shaft pipe, an outer shaft pipe, a tray, a water segregator, a rotating connector B, a lower base and a lower millstone. Universal polishing of the jig disc is achieved through the self-aligning bearing, so that the polishing strength of products at different positions on the jig disc is consistent; meanwhile, the inner shaft pipe and the outer shaft pipe are adopted for water inlet and outlet, butt joint is achieved through the rotary connector, the structure is simple, and only the rotary connector and the inner and outer shaft pipes need to be sealed.

Description

technical field [0001] The invention relates to the technical field of polishing, in particular to a water-cooled single-side polishing machine. Background technique [0002] Existing polishing machines can simultaneously polish multiple products, greatly improving polishing efficiency. However, the structure of the upper plate of the existing polishing machine has the problem of uneven polishing force, which leads to inconsistent flatness of the polished surfaces of different products on the upper grinding plate, and thus leads to a low product yield. [0003] In addition, when the existing polishing machine is polishing, a large amount of heat will be generated due to the friction between the grinding disc and the product to be polished, so it is necessary to dissipate heat from the grinding disc. Since the grinding disc is in a state of high-speed rotation during work, it is difficult to design a corresponding water-cooling structure; while the existing water-cooling str...

AI Technical Summary

Problems solved by technology

Because the grinding disc is in a state of high-speed rotation during work, it is difficult to design a corresponding water-cooling structure; while the existing water-cooling structure is complex, and the joints are difficult to seal. After a long time, water leakage is prone to occur, and additional glue is required for repair and sealing
