A kind of equipment and process method for robot automatic grinding precision gear tooth profile fillet

Abstract

The invention discloses equipment and a process method for automatically grinding precision gear tooth profile fillets by a robot. The robot module in the equipment is arranged on one side of the workbench module, and the grinding processing tool module is installed on the end effector of the robot module; In the processing tool module, the front end of the pneumatic engraving and grinding machine is equipped with a forming tool, and the pneumatic engraving and grinding machine is connected to the upper surface of the XY-horizontal slide table through the fixture and the first L-shaped connecting plate; the XY-horizontal slide table is used as a position adjustment device for the master The master model is connected through the connecting plate, and the tool setting instrument is installed on the same side of the master model; the cylinder is installed on the end effector of the robot module through the second L-shaped connecting plate; the piston of the cylinder is connected with the first L-shaped connecting plate. The equipment and method of the present invention can ensure a constant distance between the tool and the tooth profile during the grinding process, avoid processing quality problems caused by robot positioning errors, and save costs greatly because no force sensor is used for error adjustment and compensation.

Description

technical field [0001] The invention relates to the technical field of automatic processing and application of industrial robots, in particular to an equipment and a process method for automatic grinding of precision gear tooth profile fillets by a robot. Background technique [0002] Due to the high manufacturing precision and complex structure of gears in high-precision transmission and transmission equipment such as hydraulic pumps and gearboxes, the production and processing of such gears becomes very difficult. [0003] The tooth profile transition fillet of precision gears is usually ground due to its small size and high precision. The cost of grinding the gear tooth profile fillet with CNC machine tools will be greatly increased, and compared with various shapes and structures. For high-precision gears, the flexibility and adaptability of CNC machine tools are poor, and the working space of the machine tool will also limit the grinding of larger-sized ring gear tooth ...

AI Technical Summary

Problems solved by technology

[0004] Aiming at the problems of high-precision gear tooth profile transition fillet processing in the prior art, it is difficult to guarantee the processing quality of the gear tooth profile transition fillet, and the working hours are long, the noise is large, and there is much dust. This invention proposes a robot that automatically grinds precision gear teeth. The equipment and method of profile fillet can realize the automatic grinding process of transition fillet of precision gear tooth profile, so as to replace the current manual processing
