Abstract

The invention discloses a braking separation type liquid metal grinding disc device. The device comprises an air cylinder barrel, an air cylinder bottom plate, an air cylinder top plate, a braking device and a driving air cylinder, wherein the air cylinder bottom plate is fixed to the bottom of the vertically-arranged cylindrical air cylinder barrel, the braking device is integrally in a cylindrical piston shape and is installed in the cylindrical air cylinder barrel, the driving air cylinder is fixed to the air cylinder bottom plate, the movable end of the driving air cylinder is connected with the bottom of the braking device, the driving air cylinder moves to push the braking device to move up and down along the air cylinder barrel, the braking device comprises a cylindrical piston shell, an electrode layer, a heat conduction layer, a refrigeration layer and a heating layer, and the electrode layer, the heat conduction layer, the refrigeration layer and the heating layer are sequentially arranged in the piston shell from top to bottom. According to the device, a grinding disc made of liquid metal polishing solution can be rapidly generated, the process for manufacturing the grinding disc is simple, waste of materials is avoided, the abraded grinding disc can be recycled, and the manufactured grinding disc is higher in precision.

Description

technical field [0001] The invention relates to the field of liquid metal polishing, in particular to a brake separation type liquid metal grinding disc device. Background technique [0002] Grinding is the finishing process (such as cutting) of the machined surface by using the abrasive particles coated or pressed on the grinding tool, through the relative movement of the grinding tool and the workpiece under a certain pressure. Grinding can be used to process various metal and non-metal materials. The processed surface shapes include plane, inner and outer cylindrical and conical surfaces, convex and concave spherical surfaces, threads, tooth surfaces and other profiles. The processing accuracy can reach IT5~01, and the surface roughness can reach Ra0.63~0.01 microns. [0003] The manufacture of existing grinding discs generally adopts abrasive materials, fillers and glue as a mixed liquid, which is made into grinding discs through firing or pressing. The processing envi...
