A driving assembly 8 is provided on the front side of the processing frame 1. The driving assembly 8 includes a DC motor 81 located on the rear side of the processing frame 1. The DC motor 81 is fixedly installed at the rear end of the left movable frame 5. The output shaft of the DC motor 81 is fixedly connected to the rotating column 4 on the left. The front end of the rotating column 4 on the left is fixedly connected to a first pulley 82. The front surface of the limiting slider 10 on the right is rotatably connected to a rotating rod 83 through a bearing. A slidable sliding seat 84 is provided on the front side of the processing frame 1. The front end of the sliding seat 84 is rotatably connected to a tensioning pulley 85. The surface of the rotating rod 83 is rotatably connected to a second belt pulley 86. The rotating rod 83 and The surface of the right rotating column 4 is fixedly connected with a gear 12, and the two gears 12 are meshed with each other. The first pulley 82, the rotating rod 83 and the tensioning pulley 85 are connected through belt transmission. Through the setting of the driving component 8, the DC motor 81 drives, the first pulley 82 and the second belt pulley 86 are used in coordination, and the rotating rod 83 and the left rotating column 4 are driven to rotate. At the same time, under the meshing transmission of the two gears 12, the two rotating columns 4 can rotate towards each other, and then the two polishing wheels 3 can rotate towards each other, and the force sensitive sensor is polished. A tensioning component 9 is arranged on the front side of the processing frame 1.

At the same time, under the meshing transmission action of the two gears 12, the rotating column 4 on the right rotates in the opposite direction, so that the two polishing wheels 3 rotate in the opposite direction to polish the surface of the force sensitive sensor. In the process of movement of the two rotating columns 4, the first pulley 82 and the second pulley 86 are displaced. At this time, under the traction of the belt, the sliding seat 84 and the tensioning pulley 85 move up and down adaptively, the sliding pin 93 slides in the inner cavity of the guide tube 91, and the spring 94 compresses or expands itself.
