[0023] Working principle: When using this device, first, the grinding robotic arm is fixedly connected to the mounting plate 13, and then the mounting flange 5 is connected to the grinding equipment. When the grinding equipment is replaced, it is only necessary to separate the grinding equipment from the mounting flange 5. The movement of the grinding robotic arm drives the processing of the grinding equipment, and then the workpiece is ground by the operation of the grinding equipment. During the grinding process, air is injected into the airbag 8 through the air supply pipe 10 and the air vent pipe 18. The deformation of the airbag 8 is adjusted by the different gas pressure inside the airbag 8. During the deformation process, the airbag 8 is in contact with the inner wall of the limiting tube 20 through the limiting roller 26 set on the limiting rod 19, thereby limiting the deformation direction of the airbag 8, improving the grinding accuracy of the device, and thus driving the grinding force between the grinding equipment and the workpiece. This avoids the reduction of the surface quality of the workpiece by manual grinding, thereby reducing grinding errors.
