Automatic grinding wheel replacement device and method for industrial robot

Abstract

The invention discloses an automatic grinding wheel replacement device and method for an industrial robot. Replacement of grinding wheels of different sizes are achieved through a dual-layer replacement support, a plurality of spare grinding wheels are placed by a spare grinding wheel supporting rack, and the spare grinding wheel is pushed to a position where the grinding wheel is about to be replaced by a spare grinding wheel pushing mechanism. A grinding wheel nut is removed and tightened through a grinding wheel nut removing device. After being removed, a worn grinding wheel can freely rolldown from a grinding wheel support, and a discarded grinding wheel collecting box is arranged on the corresponding side of a replacement platform, so that the grinding wheels which are replaced are intensively collected. The device is compact and reasonable in structure, it can be achieved that the grinding wheel is automatically replaced, it can be also achieved that the spare grinding wheel isautomatically loaded, and a plurality of structurally similar dual-layer replacement supports and removing devices are arranged on the device platform, so that it is achieved that the grinding wheelsof various sizes are automatically replaced. The automatic degree and the working efficiency of the whole device are greatly improved. The whole device is reasonable in structure, and the applicationoccasion is wide.

Description

technical field [0001] The invention relates to the technical field of automatic tool changing devices for industrial robots, in particular to an automatic changing device and method for grinding wheels used in industrial robots. Background technique [0002] Industrial robots are important automation equipment for intelligent manufacturing. The grinding robot replaces manual grinding and polishing operations. It is mainly used for surface grinding and polishing of workpieces, and is widely used in the automotive industry, bathroom hardware industry, IT industry and other industries. In various grinding operations, the grinding wheel will wear to varying degrees after a period of use, which will not only affect the grinding quality but also pose certain safety hazards. On-demand wheel replacement is an important task in grinding and polishing operations. [0003] Most of the existing grinding wheels are replaced manually. This method requires shutdown, which is time-consum...

AI Technical Summary

Problems solved by technology

[0003] Most of the existing grinding wheels are replaced manually. This method needs to be shut down, which takes a long time and has a slow cycle, which greatly affects the work efficiency.

At present, the existing automatic grinding wheel changing device can generally only realize one grinding wheel replacement. The new grinding wheel and the replaced grinding wheel still need to be handled manually, and the degree of automation is low.
