Abstract

The invention discloses a two-workstation polycrystalline diamond compact polisher and solves the problem that existing polishers are unreliable in polishing quality and low in polishing efficiency due to unreasonable structure. The polisher comprises a polishing wheel base and a polycrystalline diamond compact clamp seat, a polishing wheel set is arranged in the polishing wheel base and comprisesa driving shell fixedly connected with the polishing wheel base, a plurality of eccentric shafts are arranged on the bottom side of the driving shell, the eccentric shafts are in transmission connection through an eccentric shaft seat, a polishing wheel driving shaft in planet motion is arranged in the eccentric shaft seat, a polishing wheel is fixedly arranged at the upper end of the polishing wheel driving shaft, a waterproof cooling shell is arranged on the periphery of the polishing wheel, a labyrinth sealing structure is arranged between the waterproof cooling shell and the polishing wheel, a closed circulating cooling cavity is formed between the waterproof cooling shell and the polishing wheel, and the polycrystalline diamond compact clamp seat has multiple degrees of freedom. Thetwo-workstation polycrystalline diamond compact polisher is novel in structure and convenient and reliable in polishing and has good popularization and application prospect.

Description

technical field [0001] The invention relates to the technical field of mechanical polishing, in particular to a two-station polycrystalline diamond composite sheet polishing machine. Background technique [0002] Polycrystalline Diamond (PCD) composite sheet is a kind of composite material, which is made by spreading artificial diamond powder and adhesive on the cemented carbide substrate, and pressing it under high temperature and high pressure. The polycrystalline diamond composite sheet integrates the high wear resistance of polycrystalline diamond and the high impact resistance of cemented carbide, and its cutting performance is extremely excellent. It is made into various cutting tools for precision cutting of non-ferrous metals and their alloys, high-hardness materials, non-metallic materials and reinforced composite materials. The tool made of polycrystalline diamond composite sheet can not only greatly improve the durability of the tool, but also improve the cutting...
