Detailed Implementation

[0025] 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.

[0026] Reference Figure 1-6 An embodiment of this utility model provides an electrophoretic coating hanger, including a connecting mechanism 3 and a base layer 4. A crossbeam 1 is fixedly installed on both sides of the connecting mechanism 3, and multiple hanging mechanisms 2 are fixedly installed on the upper ends of the two crossbeams 1. A first reinforcing layer 5 is fixedly installed on the outer surface of the base layer 4, and a second reinforcing layer 6 is fixedly installed on the outer surface of the first reinforcing layer 5. The base layer 4 is made of stainless steel, the first reinforcing layer 5 is made of epoxy coating, and the second reinforcing layer 6 is made of polytetrafluoroethylene coating.

[0027] Specifically, the crossbeam 1 provides support for the hanging mechanism 2, assists in hanging workpieces, and ensures the integrity of the hanger structure. The hanging mechanism 2 can adjust the height and angle of the hook 206 to accurately hang workpieces, prevent them from falling or shaking, and ensure uniform coating. The connecting mechanism 3 can connect various components, can adjust the width, and realize the connection between the hanger and the production line equipment to ensure mobile operation. The base layer 4 provides a stable structural frame, bears weight and stress, is corrosion resistant, and ensures the overall stability of the hanger. The first reinforcing layer 5 is made of epoxy coating. With the excellent adhesion of epoxy coating, it adheres tightly to the base layer 4, further enhancing the overall structural strength of the hanger, making the hanger more stable and reliable when hanging car engine brackets. The second reinforcement 6 is made of polytetrafluoroethylene coating, which fully utilizes the characteristics of polytetrafluoroethylene. Its extremely low coefficient of friction makes the operation of hanging and removing car engine brackets smoother.

[0028] Reference Figure 1 , Figure 4Each of the multiple hooking mechanisms 2 includes a threaded rod 202, a fixing block 203, and a hook 206. The lower end of each of the multiple threaded rods 202 is fixedly provided with a damping shaft 204. The lower end of each of the multiple damping shafts 204 is threadedly provided with a connecting rod 205. The upper end of each of the multiple threaded rods 202 is fixedly provided with an adjusting block 201. Each of the multiple threaded rods 202 is threaded inside the fixing block 203. The side of each of the multiple connecting rods 205 away from the damping shaft 204 is fixedly connected to the hook 206. Each of the multiple fixing blocks 203 is fixedly provided on the upper end of the crossbeam 1.

[0029] Specifically, the adjusting block 201 facilitates the operator's rotation of the threaded rod 202. By rotating the adjusting block 201, the threaded rod 202 rotates within the fixed block 203, thereby enabling the threaded rod 202 to move up and down. The fixed block 203 is firmly fixed to the upper end of the crossbeam 1, providing a stable support point for the hooking mechanism 2. The damping shaft 204 has certain damping characteristics. When the connecting rod 205 is threadedly connected to the lower end of the damping shaft 204, after adjusting the angle of the hook 206, the damping shaft 204 can effectively prevent the connecting rod 205 from rotating arbitrarily, ensuring that the hook 206 is kept at the set angle position for better hooking of different models of car engine brackets. The hook 206, through its fixed connection with the connecting rod 205, directly contacts the engine bracket. Its shape and size design can adapt to the hooking needs of various types of engine brackets. When hooking the bracket, it can firmly hook the bracket, preventing the bracket from falling off or shaking during the electrophoretic coating process, thus ensuring the uniformity and stability of the electrophoretic coating.

[0030] Reference Figure 3 , Figure 5 The connecting mechanism 3 includes two fixed plates 301 and a connecting block 306. A movable plate 303 is slidably arranged inside each of the two fixed plates 301. Multiple bolt holes 304 are opened on both sides of the upper end of each of the two movable plates 303. Fixed bolts 302 are threaded on both sides of the upper end of each of the two fixed plates 301. The side of each movable plate 303 away from the fixed plate 301 is fixedly connected to the connecting block 306. A connecting column 305 is fixedly arranged on the upper end of the connecting block 306.

[0031] Specifically, the fixed plate 301 is the basic fixed component of the connecting mechanism 3. The movable plate 303 can slide inside the fixed plate 301. This sliding structure allows the overall width of the connecting mechanism 3 to be flexibly adjusted according to actual needs. In the electrophoretic coating production line for automotive engine brackets, different batches or models of engine brackets may require different fixture layouts and spacing settings. When it is necessary to adjust the width of the connecting mechanism 3, first loosen the fixing bolt 302, then push the movable plate 303 to slide inside the fixed plate 301 to the appropriate position, and then tighten the fixing bolt 302 to fix the movable plate 303 in the required position. The bolt holes 304 on both sides of the upper end of the movable plate 303 can be used to connect other auxiliary components or to perform further fixing and installation operations. The connecting block 306 connects the two movable plates 303 together to form an integral connecting structure. The connecting post 305 set at the upper end of the connecting block 306 is used to connect with the transmission device of the electrophoretic coating production line to realize the movement and lifting operation of the fixture during the electrophoretic coating process, ensuring the smooth progress of the entire electrophoretic coating process.

[0032] Working Principle: When using this electrophoretic coating fixture to perform electrophoretic coating on an automotive engine bracket, firstly, based on the specific size and shape of the engine bracket to be electrophoretically coated, the height and angle of the hook 206 are adjusted by operating the adjusting block 201 on the hanging mechanism 2 to accurately hook the bracket. Utilizing the characteristics of the damping shaft 204, the hook 206 maintains a stable posture after hooking the bracket. Then, according to the installation requirements of the electrophoretic coating production line and the actual working scenario, the width of the connecting mechanism 3 is adjusted. This is achieved by loosening the fixing bolt 302, sliding the moving plate 303 to the appropriate position, and then tightening the fixing bolt 302. 2. After adjusting the connecting mechanism 3, connect the connecting column 305 to the corresponding equipment so that the hanger can move smoothly in the production line. When the hanger is full of engine brackets and enters the electrophoresis tank, the base layer 4 and its first reinforcing layer 5 and second reinforcing layer 6 begin to play their roles. The base layer 4 ensures the overall structural stability of the hanger, the first reinforcing layer 5 helps to enhance the structural strength and improve chemical resistance, and the second reinforcing layer 6 reduces the friction between the bracket and the hanger and resists chemical corrosion. During the electrophoresis process, the current is conducted through the hanger to the surface of the engine bracket, so that the electrophoretic paint is evenly adhered to the bracket, completing the electrophoretic coating operation.

[0033] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
