Abstract

The invention provides hand-imitating silicon carbide dissociating abrasive polishing equipment and method. The equipment comprises a robot base, a robot, an end-of-arm tool, a workpiece placing tableand a clamping mechanism, wherein the end-of-arm tool is composed of a connecting flange, a spindle holding seat, a high-speed spindle and a wool wheel and is used for polishing a silicon carbide part, the required optimal speed can be obtained by changing the rotating speed of the high-speed spindle, and the wool wheel can be replaced with a diamond grinding wheel so as to grind the part. The clamping mechanism is fixed on the workpiece placing table and used for positioning and clamping the silicon carbide part, and the clamping mechanism comprises a fixed part, a movable part, a telescopiccylinder used for enabling the movable part to act, a guide rail and a sliding block, wherein the telescopic cylinder is fixed to the workpiece placing table through a mounting support, the part canbe quickly clamped and positioned, the fixed part and the movable part are provided with rubber, and thus the silicon carbide part can be prevented from being damaged during clamping.

Description

technical field [0001] The invention relates to the technical field of grinding and polishing, in particular to a human-like silicon carbide free abrasive polishing equipment and method. Background technique [0002] Silicon carbide has the characteristics of high elastic modulus, high hardness, high temperature resistance and small thermal expansion coefficient, and is widely used in the mold industry. However, due to the very high surface hardness of silicon carbide, it is very difficult to polish the surface precisely, and it is difficult to obtain a high-quality surface. Therefore, a high-efficiency and high-quality silicon carbide polishing equipment and method are very necessary. At present, there are many polishing methods such as ultrasonic assisted polishing and electrochemical polishing, but all of them can only obtain high quality when polishing a flat surface, and the effect is not ideal when performing round corner polishing. At present, the best way of polishin...
