The cleaning assembly 5 is set on the top of the processing table 1. The cleaning assembly 5 includes a cleaning frame 51 set on the top of the processing table 1. Both ends of the cleaning frame 51 are provided with movable columns 52, which support the cleaning frame 51. A conveying hose 53 is fixedly connected inside the cleaning frame 51. A fan 54 is set at one end of the conveying hose 53. The inside of the conveying hose 53 is connected to the inside of the fan 54. With the cooperation of the conveying hose 53, it is convenient to suck up and convey dust and impurities on the processing table 1, thereby improving the cleaning effect.

[0025] refer to Figure 1 and Figure 2As shown, the outer side of the positioning frame 43 is threaded with a nut 6. The positioning frame 43 is easily fixed to the fixing plate 41 through the mounting hole 42, the connecting plate 44 and the two nuts 6. The bottom of the connecting plate 44 is fixedly connected with a mounting base 7. The inside of the mounting base 7 is fixedly connected with a fixing cylinder 8 by bolts. The inside of the fixing cylinder 8 is fixedly connected with a cylinder 9. The mounting base 7 and the fixing cylinder 8 facilitate the installation and fixing of the cylinder 9. The piston rod of the cylinder 9 is fixedly connected with a first connecting rod 10. One end of the first connecting rod 10 is fixedly connected with a positioning plate 11. One end of the positioning plate 11 is fixedly connected with a pressure block 12. The cylinder 9 and the first connecting rod 10 facilitate the descent of the positioning plate 11 and the pressure block 12, and the pressure block 12 presses and fixes the automotive sheet metal.

[0026] refer to Figure 1 , Figure 3 and Figure 4 As shown, the movable column 52 is internally threaded with a threaded rod 13. Support blocks 14 are rotatably connected to both ends of the threaded rod 13. One side of each support block 14 is fixedly connected to one side of the support plate 2. Two support blocks 14 are fixed to each side of the support plate 2. A second connecting rod 15 is fixedly connected to one end of the threaded rod 13. A motor 16 is mounted on one end of the second connecting rod 15, and the output end of the motor 16 is fixed to one end of the second connecting rod 15. A stabilizing rod 17 is slidably connected internally to the movable column 52, and the two ends of the stabilizing rod 17 are fixed by the other two support blocks 14. A collection tank 18 is fixedly connected to the bottom of the blower 54. The collection tank 18 is equipped with a tank door, which is convenient to open and clean the stored dust and impurities. A cleaning brush 19 is fixedly connected to the inside of the cleaning frame 51. A dust suction head 20 is connected inside the conveying hose 53. Dust on the surface of the processing table 1 is removed by multiple dust suction heads 20. A fixing bolt 21 is set inside the moving column 52. An insertion hole 22 is opened inside the cleaning frame 51. The height of the cleaning frame 51 can be easily adjusted by the fixing bolt 21 and the insertion hole 22, so that the cleaning brush 19 can clean the dust remaining on the processing table 1.

[0027] Working principle: During use, the automotive sheet to be processed is placed on the processing table 1. Four positioning brackets 43 are inserted into the corresponding mounting holes 42 according to the specifications of the automotive sheet. The positioning brackets 43 are supported by the fixing plate 41, and the connecting plate 44 is inserted into the outside of the positioning brackets 43 and fixed with nuts 6. Bolts are used to easily install and fix the fixing cylinder 8, which is equipped with cylinder 9, onto the mounting base 7. Driven by cylinder 9, the first connecting rod 10 causes the positioning plate 11 to descend, causing the pressure block 12 to descend and press and fix the automotive sheet. The positioning and pressing position can be flexibly adjusted according to needs, enhancing the flexibility of processing operations. After the sheet is processed, the pressure block 12 is controlled to rise and reset. The height of the cleaning frame 51 is adjusted and fixed through the insertion hole 22 and fixing bolt 21. The cleaning brush 19 contacts the surface of the processing table 1. Driven by the motor 16, the second connecting rod 15 drives the threaded rod 13 to rotate under the support of the support block 14. This causes the moving column 52 to move the cleaning frame 51 horizontally. At the same time, another moving column 52 slides under the support of the stabilizing rod 17, which promotes and improves the stability of the movement of the cleaning frame 51. The movement of the cleaning frame 51 drives the cleaning brush 19 and multiple vacuum heads 20 to move. The conveying hose 53 has sufficient length to follow the movement of the cleaning frame 51 and the vacuum heads 20. Driven by the fan 54, the dust and impurities on the processing table 1 are conveyed to the collection tank 18 through the vacuum heads 20 and the conveying hose 53. Through the back and forth movement of the vacuum heads 20 and the cleaning brush 19, the dust and impurities are vacuumed and cleaned multiple times, improving the cleaning effect.
