Description

Technical Field

[0001] The utility model belongs to the technical field of electrophoretic coating, and in particular relates to an electrophoretic coating tool for automobile parts. Background Art

[0002] Electrophoretic coating is a coating method in which a charged workpiece connected to an electrode is placed in a water-soluble coating (electrophoretic liquid), and an electrode opposite to the charged workpiece is connected to the water-soluble coating. The resin and pigment in the coating are evenly precipitated and deposited on the surface of the charged workpiece through the physical and chemical effects generated by the electric field to form a water-insoluble paint film.

[0003] In the electrophoretic coating process of automotive parts, the hanger is an important tool for supporting and fixing the parts. The rationality of its design directly affects the uniformity and efficiency of the coating. There are many types of hangers for electrophoretic coating in the current prior art, such as an electrophoretic coating hanger with announcement number CN218580098U. The distance between adjacent hanging beams of the hanger can be adjusted according to the actual size of the workpiece. On the one hand, it can improve the applicability of the hanger to workpieces of different sizes. On the other hand, it also reflects the concept of rational use of resources in a limited space. The benefit is that the hanger can hang more workpieces at one time, which means that the number of workpieces that can be electrophoretically coated at one time is also more, thereby improving the efficiency of electrophoretic coating.

[0004] Although the above-mentioned hanger can adjust the position of the hanging beams on different levels, in actual use, the position of the hook is fixed and cannot be flexibly adjusted. Therefore, when placing parts of different sizes, the parts on the same level will cover or stack each other, thus affecting the final electrophoresis effect; and when the parts are hung by the hook, the parts need to be moved during the electrophoresis process, which will inevitably cause shaking, and the parts are easy to fall off the hook, and the stability is poor.

[0030] In order to make the purpose and advantages of the utility model more clear, the utility model is specifically described in combination with the following embodiments. It should be understood that the following text is only used to describe one or several specific implementations of the utility model, and does not strictly limit the protection scope of the specific request of the utility model.

[0031] like Figure 1-5 As shown, an electrophoretic coating tool for automobile parts includes:

[0032] A hanging rod 1, the outer wall of which is provided with a threaded groove, and the upper end of which is provided with a hook;

[0033] A hollow ring 2 is slidably sleeved on the hanging rod 1. Two cross beams 3 are connected to the outer surface of the hollow ring 2, and positioning holes 4 are evenly distributed on the cross beams 3.

[0034] The sleeve 5 is sleeved on the hanging rod 1, wherein the sleeve 5 is located below the hollow ring 2, and the inner wall of the sleeve 5 is provided with an internal thread, the sleeve 5 and the hanging rod 1 are threadedly connected through a thread groove and the internal thread, the top surface of the sleeve 5 is provided with circular grooves 9 distributed in an annular manner, and the bottom surface of the hollow ring 2 is connected with two round rods 10;

[0035] T-slot 6, T-slot 6 is provided on the crossbeam 3;

[0036] An adjusting member 7, the adjusting member 7 is arranged on the crossbeam 3;

[0037] The adjusting member 7 comprises a supporting portion 71 which is slidably connected to the beam 3 , an extending portion 72 is arranged on the supporting portion 71 , a positioning portion 73 is arranged at the top of the supporting portion 71 , and a hook body 8 is rotatably connected to the extending portion 72 .

[0038] When in use, first adjust the distance between adjacent beams 3 according to the size of the workpiece to be electrophoretically coated. Specifically, first sleeve the hollow ring 2 at the appropriate position of the hanging rod 1, and then screw the sleeve 5 along the hanging rod 1 to a position close to the hollow ring 2 until it abuts against the hollow ring 2, and then insert the round rod 10 on the bottom surface of the hollow ring 2 into the circular groove 9 on the top surface of the sleeve 5, so that the beam 3 can be blocked and supported by the sleeve 5 while maintaining a good connection stability with the sleeve 5.

[0039] Thereafter, the hollow rings 2 on the next set of cross beams 3 are sleeved on appropriate positions of the hanging rod 1, and then another sleeve 5 is screwed along the hanging rod 1 to a position close to the hollow rings 2 until it abuts against the hollow rings 2, so that the hollow rings 2 can be blocked and supported by the sleeve 5; the above operation is repeated until all the hollow rings 2 are hung on the hanging rod 1.

[0040] Through the above arrangement, the distance between the upper and lower beams 3 can be adjusted according to the actual size of the workpiece. On the one hand, it can improve the applicability of the hanger to workpieces of different sizes. On the other hand, it also reflects the concept of rational use of resources in limited space. The benefit is that the hanger can hang more workpieces at one time, which means that the number of workpieces that can be electrophoretically coated at one time is also greater, thereby improving the efficiency of electrophoretic coating.

[0041] It should be added that the sleeve 5 is made of iron, and a magnet is embedded inside the hollow ring 2, so that the hollow ring 2 and the sleeve 5 can be adsorbed together.

[0042] like Figure 3-4 As shown, the support portion 71 includes a T-shaped slider 711 , which is disposed in the T-shaped slot 6 and forms a sliding structure in the T-shaped slot 6 , and a vertical rod 712 is connected to the bottom surface of the T-shaped slider 711 .

[0043] When in use, the T-shaped slider 711 is slidably connected in the T-shaped slot 6, which facilitates the adjustment of the position of the support portion 71. The slider and the slot body are both set to be T-shaped, which can ensure sliding while also improving the stability of the connection.

[0044] like Figure 4 As shown, the extension portion 72 includes a rotating rod 721, which is rotatably connected to the vertical rod 712. The vertical rod 712 is also slidably provided with a sleeve 722. The rotating rod 721 is rotatably connected to a support rod 723, and the other end of the support rod 723 is rotatably connected to the sleeve 722. Adjustment holes 724 are evenly distributed on the vertical rod 712, and a fastening bolt 725 is provided on the sleeve 722.

[0045] When in use, after the position between adjacent support portions 71 is adjusted, the fastening bolt 725 is twisted off first, and then the sleeve 722 is pushed up and down. The rising of the sleeve 722 will drive the lower end of the support rod 723 to move upward, thereby pushing the rotating rod 721 to flip outward. Conversely, the sleeve 722 moves downward to drive the rotating rod 721 to flip inward. After the flipping angle of the rotating rod 721 is adjusted, the fastening bolt 725 is twisted into the corresponding adjustment hole 724 to fix it. Through the above arrangement, the position between the two hooks 8 on the same extension portion 72 can be adjusted.

[0046] like Figure 4 As shown, the positioning portion 73 includes an L-shaped plate 731, which is connected to the upper end of the vertical pole 712. A positioning member 732 is inserted into the L-shaped plate 731, and a spring 733 is sleeved on the positioning member 732. The positioning member 732 is composed of a cylinder, a ring and a pull ring, and the spring 733 is sleeved on the cylinder, and the two ends of the spring 733 are respectively connected to the L-shaped plate 731 and the ring.

[0047] When in use, the distance between adjacent support parts 71 is adjusted according to the size of the workpiece. Specifically, first pull the positioning piece 732 outward and stretch the spring 733, then slide the T-shaped slider 711 into the T-shaped slot 6, and then the support part 71 is moved to a suitable position, and the positioning piece 732 is loosened. At this time, the reset force generated by the spring 733 drives the positioning piece 732 to reset, so that the cylinder on the positioning piece 732 is inserted into the corresponding positioning hole 4 on the beam 3, and the above operation is repeated to complete the installation of other support parts 71. Through the above arrangement, the distance between adjacent support parts 71 can be adjusted.

[0048] like Figure 5 As shown, the hook body 8 includes a hook 81, which is rotatably connected to the lower end of the rotating rod 721. A limiting groove 82 is provided at one end of the hook 81, and the other end of the hook 81 is rotatably connected to a limiting rod 83. A compression spring 84 is connected between the limiting rod 83 and the hook 81.

[0049] When in use, after the positions between each adjacent structure are adjusted, the workpiece that needs electrophoretic coating is hung on the hook body 8. Specifically, when hanging the workpiece, the staff presses the limit rod 83 inward and squeezes the compression spring 84. At this time, the hook body 8 opens and the workpiece can be hung. After hanging, the staff loosens the limit rod 83. At this time, the compression spring 84 generates a reset force to push the limit rod 83 to reset. Then one end of the limit rod 83 is embedded in the limit groove 82. At this time, the opening of the hook body 8 is closed to lock and suspend the workpiece, ensuring that spare parts will not accidentally loosen or fall off during the coating process. The stability and safety of the hanger are fully guaranteed, which can ensure the smooth progress of the electrophoretic coating process and improve the coating efficiency.

[0050] Repeat the above operation, hang the workpiece on the hook body 8 in turn, and then lift the hanger into the water-soluble paint (electrophoretic liquid) by the crane, so that the resin and pigment in the paint are evenly precipitated and deposited on the surface of the charged workpiece to form a water-insoluble paint film.

[0051] Specifically, the key components of the hanger have been treated with wear-resistant and anti-corrosion treatments, and can resist chemical corrosion during electrophoretic fluid and coating, thereby extending the service life of the hanger.

[0052] The working principle of the utility model is:

[0053] First, adjust the distance between adjacent beams 3 according to the size of the workpiece to be electrophoretically coated. Specifically, first, sleeve the hollow ring 2 at the appropriate position of the hanging rod 1, and then screw the sleeve 5 along the hanging rod 1 to a position close to the hollow ring 2 until it abuts against the hollow ring 2, and then insert the round rod 10 on the bottom surface of the hollow ring 2 into the circular groove 9 on the top surface of the sleeve 5, so that the beam 3 can be blocked and supported by the sleeve 5 while maintaining a good connection stability with the sleeve 5.

[0054] Thereafter, the hollow rings 2 on the next set of cross beams 3 are sleeved on appropriate positions of the hanging rod 1, and then another sleeve 5 is screwed along the hanging rod 1 to a position close to the hollow rings 2 until it abuts against the hollow rings 2, so that the hollow rings 2 can be blocked and supported by the sleeve 5; the above operation is repeated until all the hollow rings 2 are hung on the hanging rod 1.

[0055] Then, the distance between adjacent support portions 71 is adjusted according to the size of the workpiece. Specifically, the positioning member 732 is first pulled outward and the spring 733 is stretched, and then the T-shaped slider 711 is slidably connected in the T-shaped slot 6. After the support portion 71 is moved to a suitable position, the positioning member 732 is loosened. At this time, the restoring force generated by the spring 733 drives the positioning member 732 to reset, so that the cylinder on the positioning member 732 is inserted into the corresponding positioning hole 4 on the beam 3. The above operation is repeated to complete the installation of other support portions 71. Through the above arrangement, the distance between adjacent support portions 71 can be adjusted;

[0056] After the position between the adjacent support parts 71 is adjusted, the fastening bolt 725 is twisted off first, and then the sleeve 722 is pushed up and down. The rise of the sleeve 722 will drive the lower end of the support rod 723 to move upward, thereby pushing the rotating rod 721 to flip outward. Conversely, the sleeve 722 moves downward to drive the rotating rod 721 to flip inward. After the flipping angle of the rotating rod 721 is adjusted, the fastening bolt 725 is twisted into the corresponding adjustment hole 724 to fix it. Through the above arrangement, the position between the two hooks 8 on the same extension part 72 can be adjusted;

[0057] After the positions between each adjacent structure are adjusted, the workpiece that needs electrophoretic coating is hung on the hook body 8. Specifically, when hanging the workpiece, the staff presses the limit rod 83 inward and squeezes the compression spring 84. At this time, the hook body 8 opens and the workpiece can be hung. After hanging, the staff loosens the limit rod 83. At this time, the compression spring 84 generates a reset force to push the limit rod 83 to reset. Then one end of the limit rod 83 is embedded in the limit groove 82. At this time, the opening of the hook body 8 is closed to lock and suspend the workpiece, ensuring that spare parts will not accidentally loosen or fall off during the coating process. The stability and safety of the hanger are fully guaranteed, which can ensure the smooth progress of the electrophoretic coating process and improve the coating efficiency.

[0058] Repeat the above operation, hang the workpiece on the hook body 8 in turn, and then lift the hanger into the water-soluble paint (electrophoretic liquid) by the crane, so that the resin and pigment in the paint are evenly precipitated and deposited on the surface of the charged workpiece to form a water-insoluble paint film.

[0059] The above is only a preferred embodiment of the present invention. It should be noted that, for ordinary technicians in the technical field, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be regarded as the protection scope of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to the conventional means in the field unless otherwise specified and limited.
