[0002] Metal workpieces mainly include iron, copper, aluminum, nickel, tungsten, molybdenum, cobalt, etc., and metal materials refer to materials with properties such as luster, ductility, and heat transfer. During the production and processing of metal workpieces, a surface wear-resistant treatment process is required to increase the service life of metal workpieces.

[0003] The existing wear-resistant treatment of metal workpieces is to spray a wear-resistant agent on the metal workpieces to achieve the effect of increasing wear resistance.

A connecting frame 5 is fixedly arranged between the two operating tables 1. A cleaning assembly is arranged inside the connecting frame 5. The cleaning assembly includes a water tank 3 and a rectangular frame 2. The water tank 3 is fixedly arranged on the bottom surface of the connecting frame 5. The rectangular frame 2 is fixedly arranged on the top surface of the connecting frame 5. A convex plate 27 is fixedly arranged inside the water tank 3. Drain ports 28 are respectively provided through both sides of the water tank 3. The two drain ports 28 respectively correspond to the inclined low ends at both ends of the convex plate 27. Connecting blocks 22 are fixedly arranged on the inner walls of the four sides of the rectangular frame 2. A ring 26 is fixedly arranged between the four connecting blocks 22. A rectangular block 24 is fixedly arranged on the inner wall of the ring 26. A branch pipe 23 is fixedly arranged inside the rectangular block 24. One end of the branch pipe 23 penetrates through the rectangular block 24 and extends outward to be connected with a sprayer head 25. A water inlet pipe is fixedly arranged on the outer wall of the rectangular block 24. The water inlet pipe is connected to an external water source through a water pump. Cleaning water is transported into the branch pipe 23 through the water inlet pipe and then sprayed out by the sprayer head 25 to pre-clean the outer surface of the pipe fittings inside the ring 26, facilitating subsequent operations on the pipe fittings. The sewage generated by cleaning drips to the bottom of the water tank 3. The convex plate 27 diverts the sewage, and finally the sewage is discharged through the drain port 28.

[0021] Referring to Figures 1-2, at opposite ends of the top surfaces of the two operating platforms 1, two connecting plates 19 are fixedly provided. Between the left and right connecting plates 19, guide rods 18 are fixedly provided. Between the two guide rods 18, a first circular plate 16 and a second circular plate 10 are provided. On the outer walls of the first circular plate 16 and the second circular plate 10, two sliding plates 8 are symmetrically and fixedly provided. The two sliding plates 8 are respectively slidably connected to the two guide rods 18. On both the first circular plate 16 and the second circular plate 10, support rods are passed through by bearings. At the opposite ends of the support rods, rotating plates 11 are fixedly provided. On the opposite side wall surfaces of the rotating plates 11, brackets 12 are fixedly provided. Inside the brackets 12, bidirectional threaded rods 15 are rotatably passed through. At both ends of the bidirectional threaded rods 15, collar rings 6 are fixedly sleeved. On the outer walls of the collar rings 6, clamping plates 14 and sliders 7 are symmetrically and fixedly provided respectively. On the outer walls of the brackets 12, chutes 9 are penetrated. The sliders 7 are slidably connected to the chutes 9. The top ends of the bidirectional threaded rods 15 penetrate through the brackets 12 and extend upward to be fixedly connected to turning knobs 13. By rotating the two turning knobs 13, the rotation of the turning knobs 13 drives the bidirectional threaded rods 15 to rotate. The rotation of the bidirectional threaded rods 15 drives the two collar rings 6 and the sliders 7 thereon to move relatively along the vertical direction of the chutes 9. The relative movement of the two collar rings 6 drives the two clamping plates 14 to move relatively, so as to be able to clamp pipe fittings with different diameters;

[0022] The other end of the support rod on the first circular plate 16 penetrates through the first circular plate 16 and extends outward to be connected to a motor 17. On the other side of the operating platform 1 on the left, a side plate 21 is connected. On the top surface of the side plate 21, a hydraulic cylinder 20 is provided. The output end of the hydraulic cylinder 20 is connected to the first circular plate 16. By driving the support rod thereon by the output end of the motor 17 to rotate, the rotation of the support rod drives the rotating plate 11 thereon to rotate. The rotation of the rotating plate 11 drives the bracket 12, the pipe fitting, and the other rotating plate 11 and the support rod thereon to rotate, realizing the 360-degree rotation of the pipe fitting. And by driving the first circular plate 16 and the two sliding plates 8 thereon along the guide rod 18 in the direction of the hydraulic cylinder 20 by the output end of the hydraulic cylinder 20, the movement of the first circular plate 16 drives the pipe fitting and the second circular plate 10 to move, so that the nozzle 25 can perform all-round spraying and washing on the outer surface of the pipe fitting.

[0023] The implementation principle of a surface pretreatment device for metal workpieces in an embodiment of this application is as follows: When in use, first rotate two rotary knobs 13. The rotation of the rotary knobs 13 drives the bidirectional threaded rod 15 to rotate. The rotation of the bidirectional threaded rod 15 drives two collars 6 and sliders 7 thereon to move relative to each other along the vertical direction of the chute 9. The relative movement of the two collars 6 drives the two clamping plates 14 to move relative to each other to clamp the pipe fitting. Then, the output end of the motor 17 drives the support rod thereon to rotate. The rotation of the support rod drives the rotating plate 11 thereon to rotate. The rotation of the rotating plate 11 drives the bracket 12, the pipe fitting, and the other rotating plate 11 and the support rod thereon to rotate, realizing 360-degree rotation of the pipe fitting. And the output end of the hydraulic cylinder 20 drives the first circular plate 16 and two sliding plates 8 thereon to move horizontally along the guide rod 18 towards the direction of the hydraulic cylinder 20. The movement of the first circular plate 16 drives the pipe fitting and the second circular plate 10 to move. At the same time, the water pipe is connected to an external water source through a water pump. The cleaning water is transported to the inside of the branch pipe 23 through the water inlet pipe and then sprayed out by the nozzle 25 to realize pre-cleaning of the outer surface of the pipe fitting inside the circular ring 26, facilitating subsequent operations on the pipe fitting. The sewage generated by the cleaning drops to the bottom of the water tank 3, and the sewage is diverted by the convex plate 27 and finally discharged through the sewage outlet 28.
