Technical Field

[0001] This utility model relates to the field of metal parts processing technology, specifically to a surface treatment device for metal parts processing. Background Technology

[0002] Surface treatment equipment in metal parts processing is mainly used to improve the performance and appearance of metal surfaces. Common surface treatment methods include electroplating, electroless plating, anodizing, thermal spraying, sandblasting, and polishing. These treatments not only enhance the aesthetics of the products but also improve their corrosion resistance, wear resistance, and other physicochemical properties.

[0003] Existing surface treatment devices for metal parts processing can be referenced from Chinese Utility Model Patent Publication No. CN220072556 U, which discloses a surface treatment device for metal parts, comprising: a body, wherein the body has a receiving cavity, two booster pumps are provided on the top of the body, the booster pumps are provided with water outlet pipes, the water outlet pipes pass through the body and connect the receiving cavity and the booster pumps, and the water outlet pipes are provided with a nozzle at one end of the receiving cavity; a filter table, wherein the filter table is provided in the receiving cavity and the filter table is provided with filter holes; a brush head, wherein the brush head is provided above the filter table, one end of the brush head is provided with a connecting rod, the connecting rod is connected to the output end of a motor; and a collection box, wherein the collection box is provided in the receiving cavity below the filter table, and the top of the collection box is open. This utility model uses high-pressure spray nozzles to keep the metal parts in a solution-immersed state, thereby enhancing the cleaning ability.

[0004] The above-mentioned device has good performance, but it still has some defects in actual use. First, the device places the metal parts directly on the filter table, and the device itself lacks a corresponding fixing mechanism. The lack of a fixing mechanism will cause the metal parts to move continuously during the cleaning process, and the distance and angle between the nozzle and the workpiece will change, affecting the rinsing effect. Second, the distance between the nozzle and the filter table is fixed, and the distance between the nozzle and the metal parts cannot be adjusted. It is also impossible to adjust the water pressure according to different workpiece shapes or cleaning requirements, which may not be able to completely remove impurities. Utility Model Content

After the surface treatment is completed, the controller reverses the motor, and the bidirectional threaded rod rotates in the opposite direction, causing the moving plates to move in the opposite direction. The push rod drives the clamping plates away from each other, causing the abutment rods to disengage from the metal parts. The springs rebound and the abutment rods return to their original positions, ready for the next clamping. Attached Figure Description

[0030] Furthermore, the movable plate 16 is slidably connected to the guide rod 20, and the bidirectional threaded rod 19 is fixedly sleeved with a worm gear 21 at the center of the inner surface of the mounting shell 17. The top of the worm gear 21 is meshed with a worm 22, and a first rotating shaft 501 is rotatably set inside the mounting shell 17 above the worm 22. The end of the worm 22 away from the processing box 1 extends to the rear side of the mounting shell 17 and is rotatably connected to it.

[0031] Furthermore, the first rotating shaft 501 and the worm gear 22 are both fixedly fitted with main transmission components 24 on the inner surface of the mounting housing 17. A secondary transmission component 25 is connected between the two main transmission components 24. A power motor 23 is fixedly connected to the rear side of the outer wall of the mounting housing 17. The output shaft of the power motor 23 is fixedly connected to one end of the worm gear 22. A protective cover 230 is provided outside the power motor 23. One side of the protective cover 230 is fixedly connected to the rear side of the mounting housing 17.

[0032] Specifically, clamping plates 13 are located on the top left and right sides of filter plate 6, and are hollow rectangular structures. Their bottoms are slidably connected to filter plate 6, allowing them to move laterally along filter plate 6. Push rods 15 are horizontally fixed at the center of the two clamping plates 13 on opposite sides, extending outwards to the outside of the processing box 1 and slidably connected thereto. Multiple abutment rods 14 are equidistantly arranged between the two clamping plates 13. One end of each abutment rod 14 near the clamping plate 13 extends into the clamping plate 13 and slidably connects thereto. A connecting spring 140 is provided at the end of each abutment rod 14 to provide elastic cushioning. The other end of the spring 140 is fixed to the inner wall of the clamping plate 13, ensuring the abutment rod 14 always has an inward restoring force. A sealing ring 130 is fitted on the outer side of each abutment rod 14, fixed to the side of the clamping plate 13 near the workpiece. The inner wall of the sealing ring 130 slides against the surface of the abutment rod 14. A U-shaped plate 18 is fixedly connected to the rear of the processing box 1. The exterior is horizontally positioned, with a bidirectional threaded rod 19 arranged parallel to the push rod 15 at the bottom.

The worm gear 22 drives the worm wheel 21 to rotate, and the worm wheel 21 drives the bidirectional threaded rod 19 to rotate. The two ends of the bidirectional threaded rod 19 are threadedly connected to the moving plates 16 on the left and right sides, respectively. As the bidirectional threaded rod 19 rotates, the two moving plates 16 move inward or outward synchronously. When moving inward, the push rod 15 pushes the clamping plate 13 closer; when moving outward, the push rod 15 separates the clamping plate 13, releasing the metal parts. The moving plates 16 slide against the guide rod 20 to ensure movement. The process is smooth and without deviation. The clamping plate 13 slides along the filter plate 6 to approach the metal fitting to be clamped. Multiple abutment rods 14 extend into the clamping plate 13 and are connected by connecting springs 140. When the front end of the abutment rod 14 contacts the metal fitting, the connecting spring 140 is compressed, automatically adapting to different thicknesses. The sealing ring 130 is sleeved on the outside of the abutment rod 14. After the surface treatment is completed, the controller 27 reverses the motor 23, and the bidirectional threaded rod 19 rotates in the opposite direction, driving the moving plate 16 to move in the opposite direction. The push rod 15 drives the clamping plates 13 to move away from each other, causing the abutment rods 14 to disengage from the metal fitting. The spring 140 rebounds and the abutment rods 14 return to their original positions, ready for the next clamping.

The top plate 201 is horizontally set and fixedly connected to the top of the electric telescopic rod 2. Its left and right ends are respectively connected to two lifting rods 301, which move up and down with the electric telescopic rod 2. The booster nozzle 3 is a high-pressure cleaning nozzle, located on the left and right sides above the filter plate 6. The top of the lifting rod 301 passes through the top of the treatment box 1 and is fixedly connected to the bottom of the top plate 201, realizing the automatic adjustment function of the height of the booster nozzle 3. It can be flexibly adapted to the height and shape of different metal parts, thereby optimizing the spray angle and cleaning intensity. The U-shaped tube 4 is set between the rear sides of the two booster nozzles 3, and its two ends are fixedly connected to the nozzles 3 to form a unified liquid supply channel, realizing synchronous liquid supply of the two nozzles and ensuring cleaning uniformity. The corrugated water inlet pipe 401 is fixedly connected to The cleaning fluid is connected to the center of the top of the U-shaped tube 4, with one end extending away from the U-shaped tube 4 to the outside of the treatment tank 1 and connected to an external water pump.

The water pump 10 is installed on the return tank 9 to realize the recycling of the cleaning fluid, which is energy-saving and environmentally friendly. The cleaning fluid tank 11 is fixedly connected to the top of the left outer wall of the treatment tank 1, and the top is provided with an openable tank cover 12 for easy addition or replacement of the cleaning fluid. Since the collection tank 7, filter device 8, return tank 9, water pump 10, cleaning fluid tank 11 and tank cover 12 are all disclosed in detail in the reference patent, this application will not elaborate further.

[0038] Furthermore, the metal parts to be processed are placed above the filter plate 6. The power motor 23 is started by the controller 27 to push the clamping plate 13 to move, so that multiple abutment rods 14 automatically fit and clamp the workpiece under the action of the connecting spring 140. The electric telescopic rod 2 is started to adjust the height of the top plate 201, thereby driving the pressure nozzle 3 to adjust up and down to a suitable position. The water pump 10 draws liquid from the cleaning liquid tank 11, which is purified through the return tank 9 and the filter device 8. The two pressure nozzles 3, together with the cleaning brush 5, rotate through the first rotating shaft 501 to mechanically brush the workpiece, thereby enhancing the cleaning effect.

[0039] Working principle: The metal parts to be processed are placed on top of the filter plate 6. The controller 27 starts the power motor 23 to move the clamping plate 13, so that multiple abutment rods 14 automatically adhere to the workpiece and clamp it under the action of the connecting spring 140. The electric telescopic rod 2 is started to adjust the height of the top plate 201, thereby driving the pressure nozzle 3 to adjust up and down to the appropriate position. The water pump 10 draws liquid from the cleaning liquid tank 11, which is purified through the return tank 9 and the filter device 8. The two pressure nozzles 3, together with the cleaning brush 5, rotate through the first rotating shaft 501 to mechanically brush the workpiece, enhancing the cleaning effect. After the controller 27 issues a command, the power motor 23 starts to run. The output shaft of the power motor 23 is directly connected to the worm gear 22, transmitting power to the worm gear 22. The worm gear 22 drives the worm wheel 21 to rotate, and the worm wheel 21 drives the bidirectional threaded rod 19 to rotate. The two ends of the bidirectional threaded rod 19 are respectively threaded to the moving plates 16 on the left and right sides. When the threaded rod 19 rotates, the two moving plates 16 move inward or outward simultaneously. When moving inward, the push rod 15 pushes the clamping plate 13 closer, and when moving outward, the push rod 15 separates the clamping plate 13, releasing the metal fitting. The moving plate 16 and the guide rod 20 slide together to ensure smooth movement without deviation. The clamping plate 13 slides along the filter plate 6 to approach the metal fitting to be clamped. Multiple abutment rods 14 extend into the clamping plate 13 and are connected by a connecting spring 140. When the front end of the abutment rod 14 contacts the metal fitting, the connecting spring 140 is compressed, automatically adapting to different thicknesses. The sealing ring 130 is sleeved on the outside of the abutment rod 14. After the surface treatment is completed, the controller 27 reverses the motor 23, and the bidirectional threaded rod 19 rotates in the opposite direction, causing the moving plate 16 to move in the opposite direction. The push rod 15 drives the clamping plates 13 to move away from each other, causing the abutment rod 14 to disengage from the metal fitting. The spring 140 rebounds and the abutment rod 14 returns to its original position, ready for the next clamping.

[0040] In summary: the design of the abutment rod 14 and connecting spring 140 allows for automatic adjustment of the clamping force according to the actual size of the workpiece, ensuring stable clamping without damaging the workpiece. The even distribution of multiple abutment rods 14 provides more stable support. The power motor 23, in conjunction with the worm gear 21 and worm 22, enables precise control of the bidirectional threaded rod 19, ensuring synchronous movement of the clamping plates 13 on both sides and preventing offset. The combination of the electric telescopic rod 2 and the lifting rod 301 allows for height adjustment of the booster nozzle 3, enabling adjustment of the distance of the booster nozzle 3 according to the needs of different workpieces, optimizing cleaning intensity and coverage. The corrugated water inlet pipe 401 ensures the continuity and sealing of liquid delivery during the up-and-down movement of the booster nozzle 3, enhancing the adaptability of the equipment.
