The output ends of the two sets of second electric push rods 13 correspond to the positions of the two sets of slots in the hot water tank 8.

[0021] The metal pipe is placed between eight sets of arc-shaped support plates 16. Then, two sets of second electric push rods 13 are opened, which drive two sets of square columns 14 to move inward. After the two sets of square columns 14 extend to the inside of the metal pipe, eight sets of third electric push rods 15 are opened, which drive eight sets of arc-shaped support plates 16 to move outward.

[0023] By setting up a connecting seat 17, gear 18, and a second motor 19, the second motor 19 is turned on. The second motor 19 drives the second electric push rod 13 on the left side to rotate through the meshing of two sets of gears 18, thereby driving the metal pipe to rotate and allowing the metal pipe to fully contact the hot water and cleaning agent.

[0024] As a preferred embodiment of the above, the lifting device includes six sets of fixed plates 4, two sets of first motors 5, two sets of screws 6, and four sets of guide rods 7. The six sets of fixed plates 4 are respectively installed on the lower side of the left and right ends of the cleaning pool 1.

The bottom ends of the two sets of screws 6 are rotatably connected to the top ends of the two sets of fixed plates 4 in the middle. The output ends of the two sets of first motors 5 pass through the two sets of fixed plates 4 in the middle and are connected to the bottom ends of the two sets of screws 6.

The two sets of first motors 5 are electrically connected to the controller 12.

[0025] By setting up a fixed plate 4, a first motor 5, a screw 6, and guide rods 7, the controller 12 turns on two sets of first motors 5, which in turn drive two sets of screws 6 to rotate. The two sets of screws 6 are threadedly connected to two sets of movable frames 3, which then lift and lower. The four sets of guide rods 7 slide on the two sets of fixed plates 4 on the front and the two sets of fixed plates 4 on the rear, thus driving the metal pipe to lift and lower.

[0026] As a preferred embodiment of the above, it also includes an aeration disc 20, a hollow tube 22, and an aeration pump 23.

[0027] By setting up an aeration disc 20, nozzles 21, hollow tubes 22, and an aeration pump 23, and by turning on the aeration pump 23, air is introduced into the aeration disc 20 through the aeration pump 23 and hollow tubes 22 and sprayed out by multiple sets of nozzles 21. The impact force generated when the bubbles sprayed out by multiple sets of nozzles 21 burst remove the dirt from the metal pipes, which can improve the cleaning effect of the metal pipes.

[0028] As a preferred embodiment of the above embodiment, it also includes two sets of mounting plates 24, two sets of fourth electric push rods 25 and two sets of top blocks 26.

[0029] By setting up the mounting plate 24, the fourth electric push rod 25, and the top block 26, when it is not necessary to drive the metal pipe to rotate, by opening the two sets of fourth electric push rods 25, the two sets of fourth electric push rods 25 will drive the two sets of top blocks 26 to move downward, and the two sets of top blocks 26 will tighten and fix the two sets of second electric push rods 13, which can improve the stability of the metal pipe.

[0030] As a preferred embodiment of the above, it also includes a third motor 27, a mounting bracket 28 and a rotary joint 29.

[0031] By setting up a third motor 27, a mounting bracket 28, and a rotary joint 29, the third motor 27 is turned on, and the third motor 27 drives the aeration disc 20 to rotate through the hollow tube 22, thereby causing the bubbles sprayed from the multiple sets of nozzles 21 to rotate. This ensures that the bubbles are evenly distributed throughout the cleaning solution, avoiding excessive concentration or sparseness of local bubbles. This helps to improve the impact effect of the cleaning solution on the surface of the metal pipe, ensuring that every part is thoroughly cleaned.

[0032] As a preferred embodiment of the above embodiment, a temperature sensor 30 is also included. The temperature sensor 30 is installed inside the hot water tank 8 and is electrically connected to the controller 12.

[0035] By setting the rubber ring 31, the friction between the top block 26 and the second electric push rod 13 can be increased, thereby improving the stability of fixing the second electric push rod 13.

[0036] This utility model discloses a high-efficiency and precision surface treatment device for metal parts. During operation, a metal tube is first placed between eight sets of arc-shaped support plates 16. Then, two sets of second electric push rods 13 are activated, causing two sets of square columns 14 to move inward. Once the square columns 14 extend to the inside of the metal tube, eight sets of third electric push rods 15 are activated, causing the eight sets of arc-shaped support plates 16 to move outward. The eight sets of arc-shaped support plates 16 then expand and fix the inner wall of the metal tube. Afterward, the device is activated by the controller 12. Two sets of first motors 5 are turned on, which drive two sets of screws 6 to rotate. The two sets of screws 6 are threadedly connected to two sets of movable frames 3, which move downwards. Four sets of guide rods 7 slide on the two sets of front fixed plates 4 and the two sets of rear fixed plates 4, causing the metal pipe to move downwards. The lower part of the metal pipe is located in the hot water of the hot water tank 8. The output ends of the two sets of second electric push rods 13 are located in the two sets of slots in the hot water tank 8. Then, the second motor 19 is turned on, which drives the left side of the first motor 19 through the meshing of two sets of gears 18. The rotation of the two electric push rods 13 causes the metal pipe to rotate, ensuring full contact between the metal pipe and the hot water. Then, the two sets of first motors 5 drive the metal pipe upwards. The controller 12 then activates the four sets of first electric push rods 11, which in turn move the hot water tank 8 backwards. When the hot water tank 8 moves backwards to a point where it no longer interferes with the metal pipe, the two sets of first electric push rods 11 retract. Then, the two sets of first motors 5 drive the metal pipe downwards, immersing it in the cleaning solution in the cleaning tank 1. Afterwards, turn on the second motor 19. The second motor 19 drives the second electric push rod 13 on the left side to rotate through the meshing of two sets of gears 18, thereby driving the metal pipe to rotate. At the same time, turn on the aeration pump 23 and the third motor 27. The aeration pump 23 introduces air into the aeration disc 20 through the rotary joint 29 and the hollow tube 22, which is then sprayed out by multiple sets of nozzles 21. The third motor 27 drives the aeration disc 20 to rotate through the hollow tube 22, thereby causing the bubbles sprayed by the multiple sets of nozzles 21 to rotate. The metal pipe is then fully in contact with the cleaning solution for cleaning.
