A free-form surface robot grinding system

Abstract

The invention discloses a free-form surface robot polishing system. The system comprises a workbench, an industrial robot, a robot control cabinet, a polishing tool, a pneumatic main shaft, a connecting part, a pneumatic control cabinet and a system control cabinet. The system is high in automation degree, high in flexibility and particularly suitable for polishing a free-form surface. Specifically, the pneumatic main shaft fixed at the tail end of the industrial robot is used for clamping the polishing tool, the machined surface is tightly pressed by the polishing tool all the time by means of the pneumatic compliant force control function of the pneumatic main shaft, constant pressure is kept, the pose of the industrial robot is adjusted according to a planned route, the polishing pressure is in the normal direction of the machined surface, the polishing tool rotates at high speed through a pneumatic motor of the pneumatic main shaft, and then the industrial robot drives the polishing tool to polish a part according to the planned route.

Description

technical field [0001] The invention relates to the technical field of industrial robots, in particular to a free-form surface robot grinding system. Background technique [0002] At present, the grinding and polishing of free-form surface parts is basically done by hand-held operating tools based on experience. It is difficult to guarantee the shape and position accuracy and surface microscopic physical properties of free-form surface parts, and the manufacturing cost is high, which restricts the development of forming mold processing technology. Development; especially the current manual work is difficult to ensure the consistency of quality and processing efficiency. According to statistics, finishing processing accounts for about 37-42% of the entire mold manufacturing man-hours. The heavy work tasks and low efficiency make the development cycle of some equipment severely affected. Therefore, the grinding of free-form surfaces is a weak link in mold production and manuf...

Development; especially the current manual work is difficult to ensure the consistency of quality and processing efficiency. According to statistics, finishing processing accounts for about 37-42% of the entire mold manufacturing man-hours. The heavy work tasks and low efficiency make the development cycle of some equipment severely affected

Therefore, the grinding of free-form surfaces is a weak link in mold production and manufacturing, and has become a bottleneck restricting the development of the mold manufacturing industry.
