Abstract

The invention provides a robot end effector suitable for large thin-walled workpiece grinding and a grinding system, and belongs to the technical field of machining. The effector comprises a base connected to a robot, a driver is connected to the base, a movable seat is connected to the end, away from the base, of the driver, a length-adjustable connecting rod is arranged above the base, and the upward extending end of the connecting rod is connected with the movable seat. The grinding system comprises a carrying robot and a grinding robot which are arranged at the left end and the right end of a thin-walled workpiece respectively, the output end of the carrying robot is connected with an end effector with a force control function, the grinding robot is connected with an end executor witha vibration reduction function, the upper end and the lower end of the thin-walled workpiece are fixed, and the left end and the right end of the thin-walled workpiece are free. According to the robotend effector, grinding of large thin-walled workpieces can be achieved, and vibration during grinding is reduced.

Description

technical field [0001] The invention relates to the technical field of mechanical processing, in particular to a robot end effector and a grinding system suitable for grinding large thin-walled parts. Background technique [0002] Grinding technology is the use of abrasive tools to remove excess material or burrs on the workpiece, so as to obtain parts with smooth shape, dimensional accuracy and surface quality that meet the design requirements. It is an indispensable and important processing method in modern manufacturing. [0003] In the prior art, a utility model patent titled "An Ultrasonic Vibration Grinding Machine" with the announcement number CN 108500744 B and the announcement date of 2019.06. The workpiece clamping mechanism on the table and the ultrasonic vibration grinding mechanism that is arranged on one side of the worktable and adapted to the workpiece clamping mechanism. The ultrasonic vibration grinding mechanism includes a resonant grinding assembly that i...
