According to the usage requirements, the bracket 8 is pulled to rotate outside the workpiece frame 4, and then the processing surface of the workpiece to be processed on the surface of the bracket 8 is switched.

[0026] In this embodiment, the transposition mechanism 10 includes a rotary and revolving platform 3, a steering support plate 11, a transmission gear disk 16, and a servo motor 17. The rotary and revolving platform 3 is installed on one side of the dust-proof housing 1. A steering support plate 11 is provided at the top end of the rotary and revolving platform 3. The bottom end of the steering support plate 11 is meshed and connected with a transmission gear disk 16.

[0031] When this battery pack weld scar grinding and polishing equipment is actually applied, it includes the following working contents:

[0032] Step 1: The operator first directly places the workpiece to be processed on the surface of the workpiece frame 4, aligns the workpiece to be processed with the output end of the thrust cylinder 12, pushes one side of the workpiece to be processed through the thrust cylinder 12, makes the workpiece to be processed contact with the fixed right-angle support arranged on one side of the workpiece frame 4, completes the contact between the workpiece to be processed and the workpiece frame 4, and then releases the cylinder 6 according to the situation, so that the cylinder 6 drives the fixture 7 to descend vertically, and clamps the top end of the workpiece to be processed through the fixture 7, completing the positioning of the workpiece to be processed;

[0033] Step 2: Subsequently, the servo motor 17 is turned on, the servo motor 17 is used to drive the transmission gear disk 16 to rotate, the transmission gear disk 16 drives the annular gear disk arranged at the bottom end of the steering support plate 11 to rotate, so that the steering support plate 11 drives the symmetrically arranged workpiece frames 4 to rotate, rotates the workpiece to be processed connected to one side of the workpiece frame 4 into the dust-proof housing 1, and connects the output end of the spindle motor 14 to grinding disks with different diameters inside the tool magazine 15, and drives the grinding disk to rotate through the output end of the spindle motor 14;

[0034] Step 3: The surface of the workpiece to be processed is polished by driving a grinding disc with a spindle motor 14 through an industrial robot 13, and then the steering support plate 11 is rotated by driving a transmission gear disc 16, thereby flexibly adjusting the position of the workpiece to be processed, meeting the uniformity of the surface treatment of the workpiece to be processed, and reducing the generation of dead corners during processing;

[0035] Step 4: During the processing, by turning on the dust collector 2, a pipe fitting at the input end of the dust collector 2 is connected to the robotic arm of the industrial robot 13. When the industrial robot 13 drives the spindle motor 14 to displace, the surface debris of the plate is simultaneously sucked and cleaned by using the pipe fitting.
