Description

Technical Field

[0001] This utility model relates to the field of metal surface treatment technology, and in particular to a metal surface electrophoresis device to prevent scratches. Background Technology

[0002] Electrophoresis is short for electrophoresis phenomenon, which refers to the phenomenon that charged particles move towards the electrode with opposite charge under the action of an electric field. Nowadays, in the process of processing metal workpieces, electrophoresis process is used to immerse the surface of the metal workpieces. However, the existing metal processing electrophoresis equipment still has some defects and shortcomings that need to be improved.

[0003] In the electrophoretic processing of metal workpieces, the traditional operation mode has significant technical bottlenecks. At present, most manufacturers still adopt the extensive processing method of directly putting metal workpieces into the electrophoresis tank. This method lacks precise positioning and effective clamping of the workpieces. Due to the impact force generated by the circulating flow of the solution in the electrophoresis tank, as well as the inevitable mutual contact and friction when multiple workpieces are processed at the same time, the workpieces are very prone to displacement and collision during the electrophoresis process.

[0004] Furthermore, metal workpieces are usually precision machined and have high surface finish requirements. Direct placement can lead to scratches and other defects on the outer surface of the workpiece. These surface damages not only ruin the aesthetics of the workpiece, but more importantly, weaken the adhesion and integrity of the electrophoretic coating. Therefore, a metal surface electrophoresis device to prevent scratches is proposed to solve the above problems. Utility Model Content

[0005] To address the shortcomings of existing technologies, this invention provides a metal surface electrophoresis device to prevent scratches, thereby solving the problems mentioned in the background section.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] An electrophoresis device for preventing scratches on metal surfaces includes an electrophoresis tank with a tank cover on its top side. A lifting assembly is provided between the electrophoresis tank and the tank cover. A long groove with a cross shape is opened on the top side of the tank cover. Multiple fixing plates are fixedly installed in the long groove. Each fixing plate has a circular hole, and a threaded rod is provided in each of the circular holes. One end of each threaded rod is rotatably connected to the inner wall of one side of the long groove. The other end of each threaded rod is fixedly connected to a first bevel gear, a second bevel gear, a third bevel gear, and a fourth bevel gear. A transmission assembly is provided on one side of the first bevel gear, the second bevel gear, the third bevel gear, and the fourth bevel gear. A synchronous clamping assembly is provided on the outer side of each threaded rod.

[0008] Preferably, the lifting assembly includes a top plate fixedly installed on both sides of the tank cover, a side plate fixedly connected to both sides of the electrophoresis tank, an electric push rod fixedly connected to the bottom side of each of the two side plates, and the output ends of the two electric push rods passing through the side plates and fixedly connected to the bottom side of the two top plates respectively.

[0009] Preferably, the transmission assembly includes a fixed frame fixedly installed on the top side of the slot cover. The fixed frame is U-shaped and has a circular hole on its top side. A rotating rod is installed in the circular hole, and a transmission bevel gear is fixedly connected to the bottom end of the rotating rod. The transmission bevel gear meshes with a first bevel gear, a second bevel gear, a third bevel gear, and a fourth bevel gear, respectively.

[0010] Preferably, a handwheel is fixedly connected to the top of the rotating rod. A threaded hole and multiple threaded grooves are respectively opened on the top side of the handwheel and the fixed frame. A threaded post is threadedly installed in one of the threaded holes, and the other end of the threaded post is threadedly installed into a threaded groove that is aligned with one of the threaded holes.

[0011] Preferably, two limiting rings are fixedly sleeved on the outer side of the rotating rod, and the sides of the two limiting rings that are close to each other are respectively in contact with the top side and the inner wall of the top side of the fixing frame.

[0012] Preferably, the synchronous clamping assembly includes a long groove with multiple sliding holes on the bottom inner wall, the sliding holes being connected to the electrophoresis tank, multiple threaded rods having sliders threadedly sleeved on their outer sides, the multiple sliders being adapted to the long groove, the bottom sides of the multiple sliders being fixedly connected to connecting rods, and the multiple connecting rods being slidably installed in the multiple sliding holes respectively.

[0013] Preferably, clamps are fixedly connected to the opposite surfaces of multiple connecting rods, and anti-slip pads are fixedly connected to the opposite surfaces of multiple clamps.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. This device uses a synchronous clamping assembly and a transmission assembly to achieve synchronous clamping of the workpiece on all four sides. Turning the handwheel drives the rotating rod, which in turn drives the transmission bevel gear to drive the other four gears to rotate the threaded rod. This causes the slider to move the connecting rod and the clamping plates relative to each other, fixing the workpiece in the electrophoresis tank. Anti-slip pads on the opposite surfaces of the clamping plates prevent direct contact with the workpiece and avoid scratches. The workpiece is suspended and clamped by the clamping plates and does not come into contact with the inner wall of the electrophoresis tank, thus effectively preventing displacement and scratches caused by solution flow and workpiece collision. This ensures the surface smoothness of the workpiece and improves the adhesion and integrity of the electrophoretic coating.

[0016] 2. The two electric push rods in the lifting assembly cooperate with the top plate and side plate. The extension and retraction are controlled by the main controller, which drives the tank cover to rise and fall, realizing the automatic immersion and detachment of workpieces into and out of the electrophoresis tank, replacing manual handling. The handwheel is fixed to the fixed frame by a threaded column, and the limit ring on the outside of the rotating rod ensures stable transmission. The operator can control the opening and closing of the clamping plate by adjusting the handwheel to adapt to different specifications of workpieces. This device can reduce manual operation links, avoid operators from contacting harmful electrophoresis solutions, reduce labor intensity, and improve work efficiency and operational safety.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Reference Figure 1-4An electrophoresis device for preventing scratches on metal surfaces includes an electrophoresis tank 1, a tank cover 2 on the top side of the electrophoresis tank 1, a lifting assembly between the electrophoresis tank 1 and the tank cover 2, a long groove with a cross shape on the top side of the tank cover 2, and multiple fixing plates 3 fixedly installed inside the long groove. Each fixing plate 3 has a round hole, and each round hole has a threaded rod 4. One end of each threaded rod 4 is rotatably connected to the inner wall of one side of the long groove, and the other end of each threaded rod 4 is fixedly connected to a first bevel gear 5 and a second bevel gear 6. The third bevel gear 7 and the fourth bevel gear 8, the first bevel gear 5, the second bevel gear 6, the third bevel gear 7 and the fourth bevel gear 8 are provided with a transmission assembly on one side. Synchronous clamping assemblies are provided on the outer sides of multiple threaded rods 4. The transmission assembly includes a fixed bracket 13 fixedly mounted on the top side of the slot cover 2. The fixed bracket 13 is U-shaped, and a circular hole is opened on the top side of the fixed bracket 13. A rotating rod 14 is installed in the circular hole, and a transmission bevel gear 20 is fixedly connected to the bottom end of the rotating rod 14. The transmission bevel gear 20 is respectively connected to the first bevel gear 5, the second bevel gear 6, the third bevel gear 7, and the fourth bevel gear 8. 6. The third bevel gear 7 and the fourth bevel gear 8 mesh with each other. A transmission bevel gear 20 is provided, and because the transmission bevel gear 20 meshes with the first bevel gear 5, the second bevel gear 6, the third bevel gear 7 and the fourth bevel gear 8 respectively, under the meshing transmission of the transmission bevel gear 20, the first bevel gear 5, the second bevel gear 6, the third bevel gear 7 and the fourth bevel gear 8 will rotate counterclockwise synchronously, thereby driving the multiple threaded rods 4 connected to them to rotate counterclockwise synchronously. This causes the sliders 9, which are threaded on the outer sides of the multiple threaded rods 4, to drive the connecting rods 10 fixedly connected to the bottom side to move relative to each other. Since the opposing surfaces of the multiple connecting rods 10 are fixedly connected with clamping plates 11, the multiple clamping plates 11 can complete the synchronous clamping of the workpiece on all four sides during the relative movement. By synchronously clamping the workpiece on all four sides, the workpiece can be prevented from directly contacting the electrophoresis tank 1, thereby reducing the possibility of scratches and damage to the workpiece surface. Furthermore, the distance of movement of the multiple clamping plates 11 can be adjusted by the handwheel 15, thereby enabling the stable clamping of workpieces of various sizes.

[0024] Specifically, the lifting assembly includes top plates 21 fixedly installed on both sides of the tank cover 2, side plates 22 fixedly connected to both sides of the electrophoresis tank 1, and electric push rods 23 fixedly connected to the bottom of the two side plates 22. The output ends of the two electric push rods 23 pass through the side plates 22 and are fixedly connected to the bottom of the two top plates 21 respectively. By setting two electric push rods 23, the two electric push rods 23 can move the tank cover 2 up or down synchronously, so that the workpiece can reciprocate into the interior of the electrophoresis tank 1, and then perform electrophoresis treatment on the workpiece. This reduces the need for workers to manually pick up the workpiece, saving time and effort.

[0025] Specifically, a handwheel 15 is fixedly connected to the top of the rotating rod 14. A threaded hole 16 and multiple threaded grooves 17 are respectively opened on the top sides of the handwheel 15 and the fixed frame 13. A threaded post 18 is threaded into one of the threaded holes 16, and the other end of the threaded post 18 is threaded into the threaded groove 17 aligned with the threaded hole 16. Two limiting rings 19 are fixedly sleeved on the outer side of the rotating rod 14. The sides of the two limiting rings 19 that are close to each other are respectively in contact with the top side and the inner wall of the top side of the fixed frame 13. By providing the threaded post 18, when the workpiece is clamped by multiple clamping plates 11, the threaded post 18 is threaded into the top side. The handwheel 15 is inserted into the threaded hole 16. Then, by continuing to rotate the threaded post 18, the other end of the threaded post 18 can be threaded into the threaded groove 17 that is aligned with the threaded hole 16, thereby achieving a fixed connection between the handwheel 15 and the fixed bracket 13. By limiting the handwheel 15, the rotation rod 14 can be prevented from rotating on its own. The two limiting rings 19 fixedly sleeved on the outside of the rotation rod 14 can limit the rotation rod 14, so that it can only rotate and will not wobble left and right, thereby ensuring that the transmission bevel gear 20 is always meshed with the four bevel gears.

[0026] Specifically, the synchronous clamping assembly includes multiple sliding holes on the inner wall of the bottom side of the long groove, which are connected to the electrophoresis tank 1. Multiple threaded rods 4 are threaded with sliders 9 on their outer sides, and each slider 9 is adapted to the long groove. Connecting rods 10 are fixedly connected to the bottom side of each slider 9. The connecting rods 10 are slidably installed in the multiple sliding holes. Clamping plates 11 are fixedly connected to the opposite faces of the connecting rods 10, and anti-slip pads 12 are fixedly connected to the opposite faces of the clamping plates 11. Through the transmission assembly, the multiple sliders 9 can move synchronously relative to each other or move away from each other. During the relative movement, the clamping plates 11 move towards the four sides of the workpiece, thus completing the clamping of the workpiece. Anti-slip pads 12 are provided on the opposite faces of the clamping plates 11 to prevent the clamping plates 11 from directly contacting the workpiece, which could cause scratches on the workpiece surface.

[0027] All electrical components mentioned in this article are connected to an external main controller and 220V AC mains power. The main controller can be any conventional known device, such as a computer, that can control the operation of the electrical components mentioned in the article.

[0028] In use: When electrophoresis clamping of metal workpieces is required, the operator can hold the handwheel 15 and rotate it clockwise, which will drive the rotating rod 14 to rotate synchronously. Because the transmission bevel gear 20 fixedly connected to the bottom of the rotating rod 14 is in a perpendicular meshing state with the first bevel gear 5, the second bevel gear 6, the third bevel gear 7 and the fourth bevel gear 8 respectively, under the drive of the transmission bevel gear 20, the four bevel gears rotate counterclockwise synchronously, which in turn drives the multiple threaded rods 4 connected to each to rotate counterclockwise synchronously. The slider 9 connected to the outside of the threaded rod 4 through the threaded sleeve moves axially under the threaded transmission principle. The connecting rod 10 fixedly connected to the bottom of the slider 9 moves relative to it. Since clamping plates 11 are installed on the opposite surfaces of the connecting rod 10, under the linkage of multiple sets of sliders 9, the four clamping plates 11 can achieve synchronous and uniform clamping and fixing of the four sides of the workpiece. This four-sided clamping method allows the workpiece to completely detach from the inner wall of the electrophoresis tank 1 during the electrophoresis process, fundamentally avoiding surface scratches caused by traditional placement methods. Furthermore, operators can precisely control the opening and closing distance of the clamping plate 11 by adjusting the number of rotations of the handwheel 15, thereby achieving stable clamping of workpieces of different specifications. After the workpiece is fixed, the threaded post 18 is used to pass through the threaded holes reserved in the handwheel 15 and the fixing frame 13 to lock the position of the handwheel 15, ensuring the stability of the clamping structure during the electrophoresis process. In the workpiece electrophoresis treatment stage, the extension and retraction of the electric push rod 23 can be synchronously controlled to drive the tank cover 2 to rise and fall smoothly, realizing the fully automated operation of the workpiece automatically immersing in the electrophoresis tank 1 and detaching from the solution. This effectively replaces the cumbersome process of manually picking up and placing workpieces, not only significantly improving work efficiency but also reducing the risk of operators coming into contact with harmful electrophoresis solutions.
