The invention discloses a clamp,
system and method for
robot polishing of aero-engine blades, and belongs to the technical field of aero-engine manufacturing, the clamp comprises a fixing plate, a clamping cylinder, a tenon positioning block, a tenon pressing block and a pressing driving mechanism, and a positioning cylinder, a teaching block, a positioning block and a base plate can be additionally arranged. The blade realizes accurate positioning and anti-damage pressing through the tenon positioning block, the pressing block and the positioning cylinder, and ensures that the rotation center line of the blade coincides with the center line of the clamping cylinder; the clamping cylinder is used for being grabbed by three jaws of the
robot, the teaching block assists the
robot in rapid teaching alignment, the positioning block achieves accurate positioning of the clamp on the automatic
library frame, and the base plate is matched with blades of different models. According to the blade
polishing device, the problems that traditional manual
polishing efficiency is low, a robot is difficult to grab blades, clamping is prone to damage, and the adaptability of a clamp and a
library frame is poor can be solved, the blade polishing precision and consistency are improved, the production cost is reduced, and flexible automatic polishing of multiple types of blades can be achieved.
