Large free-form surface robot polishing system

Abstract

The invention discloses a large free-form surface robot polishing system. The large free-form surface robot polishing system comprises a pneumatic polishing head, an industrial robot, a robot control cabinet, a traveler gantry, a visual system, a pneumatic control cabinet and a system control cabinet. When the polishing system works, a part standard is rapidly and accurately calibrated according to the standard accurate calibrating technique, the traveler gantry is used for driving the industrial robot to arrive at a target free-form surface, the pneumatic polishing head is driven by the industrial robot to polish the target free-form surface according to a planed path, the pneumatic smooth force control technique and the normal polishing force control technique are adopted in a polishing process, and consistency of polishing accuracy and polishing quality is effectively guaranteed; the industrial robot is driven by the traveler gantry to arrive at the next target free-form surface after the target free-form surface is polished, the industrial robot drives the pneumatic polishing head to conduct polishing according to the planed path again, and in this way, all free-form surfaces are polished step by step in sequence. The large free-form surface robot polishing system is simple in structure, wide in work range, and suitable for polishing the large free-form surfaces.

Description

technical field [0001] The invention relates to the technical field of industrial robots, in particular to a large-scale free-form surface robot grinding system. Background technique [0002] At present, the grinding and polishing of large-scale free-form surfaces is basically done by hand-held tools based on experience, which makes it difficult to maintain uniformity in the grinding pressure and grinding path, which seriously affects the grinding quality of the product. At the same time, for larger workpieces, manual The limited grinding speed makes the processing efficiency low, and the grinding and polishing environment is harsh, which seriously threatens the health of workers. [0003] At present, in industrial applications, ABB, KUKA, FANUC and other companies have commercialized products for robot grinding systems, but most of them are for grinding small parts, and there is no perfect robot for grinding large free-form surface parts. The solution of intelligent grindi...
