Abstract

The invention provides curved surface abrasive belt grinding-polishing-laser shock peening integrated equipment and a multi-process composite process thereof. The main points of the invention comprise three points: 1, application of a quick-change module; the quick-change module can quickly change the end executive device to realize integration of multiple grinding and polishing procedures and laser surface strengthening of the curved surface workpiece, so that the processing efficiency and the automation level are improved; and 2, a composite laser shock peening process. And after grinding and polishing are completed, the equipment can be rapidly switched to the ultrafast laser emission head, the curved surface is subjected to strengthening treatment through the laser shock strengthening technology, and the fatigue life of a workpiece is effectively prolonged. And 3, application of a force control device. According to the device, the change of grinding and polishing force is monitored in real time through the six-dimensional torque sensor at the tail end of the robot, the grinding depth is controlled through the telescopic change of the air cylinder in the force control connecting seat under the condition that the linear speed of the abrasive belt and the feeding speed of the abrasive belt grinding and polishing device are fixed, the consistency of the surface machining quality of the complex curved surface is guaranteed, and the grinding and polishing efficiency is improved.
