[0001] The utility model specifically relates to the technical field of electrophoresis jigs, and particularly relates to an electrophoresis coating jig with uniform coating. Background Technique
[0002] An electrophoresis coating jig is a tool used to fix and clamp workpieces in the electrophoresis coating process. The jig needs to ensure the position of the workpiece in the electrophoresis tank. When performing electrophoresis coating, the workpiece to be coated needs to be fixed on the jig, and then the jig is immersed in the electrophoresis tank. After connecting the direct current power supply.
[0003] At present, most electrophoresis coating jigs are basically connected by hooks. When connecting lighter workpieces, the workpieces are easily separated from the hooks due to the buoyancy of the electrophoresis solution. There is also a type that uses two clamping plates and bolts between the clamping plates to achieve clamping. The workpiece is placed between the two clamping plates, and then the bolts are tightened to make the two clamping plates closely adhere to the surface of the workpiece for clamping. This type of jig needs to occupy a large position on the surface of the workpiece, and the occupied position will not be coated, affecting the coating effect. Moreover, when the workpiece moves in one direction in the electrophoresis tank, it is easy to cause the coatings on both sides of the workpiece to be uneven, affecting the electrophoresis effect. Content of the Utility Model
[0004] The purpose of the utility model is to provide an electrophoresis coating jig with uniform coating. Through the movable connection between the cross support and the rotary hanging component, the workpiece clamped at the bottom of the cross support can rotate in the electrophoresis tank, making the coating on the surface of the workpiece more uniform. To solve the technical problems raised in the above background technique.
[0005] To achieve the above purpose, the utility model provides the following technical solutions:

[0025] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.
[0026] Please refer to Figures 1-5 , an electrophoretic coating fixture with uniform coating provided by an embodiment of the present invention includes a cross-shaped bracket 1 and a rotary hanging and connecting component. The rotary hanging and connecting component is movably connected to the top of the cross-shaped bracket 1, and a plurality of lifting brackets 5 are arranged on the outer side of the cross-shaped bracket 1;
[0027] The rotary hanging and connecting component includes a T-shaped sleeve fixed at the center position of the top of the cross-shaped bracket 1. A bushing 2 is movably connected to the outer side of the T-shaped sleeve, and a hook 3 is integrally provided at the top of the bushing 2.
[0028] In this embodiment, an interference fit is provided between the outer side of the T-shaped sleeve and a bearing, and an interference fit is provided between the outer ring of the bearing and the inner side of the bushing 2.
[0029] In this embodiment, a through hole 4 is opened on the side surface of the T-shaped sleeve, and the other end of the through hole 4 extends to the inner side of the cross-shaped bracket 1.
[0030] In this embodiment, the lifting bracket 5 includes a sliding seat 51 movably connected to the end of the cross-shaped bracket 1, and a threaded knob 52 is in threaded fit at the connection between the cross-shaped bracket 1 and the sliding seat 51. A connecting seat 53 is integrally provided at the bottom of the sliding seat 51.
[0031] In this embodiment, clamping plates 54 are symmetrically provided at the bottom of the connecting seat 53, and the ends of the clamping plates 54 are movably connected to the connecting seat 53 through pins. A trapezoidal claw extending outward is integrally provided on the side of the clamping plate 54 away from the connecting seat 53.
[0032] In this embodiment, clamping plates 6 are provided on both sides of the clamping plate 54, and stud bolts penetrate through both ends of the clamping plate 6. Nuts are threadedly connected to both ends of the stud bolts.
[0033] In this factual example, a chute 55 is further formed on the side surface of the clamping plate 54, and the double-headed stud passes through the chute 55. The position between the clamping plate 54 and the clamping plate 6 is adjusted through the sliding connection between the double-headed stud and the chute 55.
[0034] By adopting the above technical solution, the end of the clamping plate 54 passes through the hole of the workpiece, and then the clamping plate 54 is separated to both sides. The position of the clamping plate 54 is fixed by the clamping plate 6 to clamp the workpiece. Then, the fixture and the workpiece are hung on the mobile device through the hook 3, and the workpiece is immersed in the electrophoresis solution. When the workpiece is light, the buoyancy of the electrophoresis solution will cause the workpiece to move upward, but the workpiece will not be separated from the clamping plate 54, and the covering area of the fixture on the surface of the workpiece is reduced. At the same time, the movable connection between the cross support 1 and the rotary hanging assembly enables the workpiece to rotate in the electrophoresis tank, so that the coating covers the workpiece more evenly, reduces the covering area of the fixture on the workpiece and prevents the workpiece from falling off the fixture, and makes the coating more uniform.
[0035] In this factual example, a groove is further formed at the bottom of the cross support 1, and the inner side of the groove is communicated with the inner side of the through hole 4.
[0036] In this factual example, a wire threading hole 56 is formed inside the connecting seat 53, and the top of the wire threading hole 56 extends to the inside of the sliding seat 51.
[0037] In this factual example, a plurality of sliding seats 51 are provided and are respectively sleeved on the outer side of the cross support 1 in an annular array, and the end of the threaded knob 52 abuts against the side surface of the cross support 1.
[0038] The working principle of the utility model is as follows: when in use, first select different numbers of lifting brackets 5 according to the hole size of the workpiece. When the hole is relatively small, a single lifting bracket 5 can be used. Insert the end of the clamping plate 54 into the hole, then separate the ends of the symmetrically arranged clamping plates 54 to both sides, and the double-headed stud in the clamping plate 6 slides inside the chute 55 until the trapezoidal claws at the end of the clamping plate 54 are stuck on the side of the hole. Then tighten the nuts at both ends of the double-headed stud, and through the extrusion between the clamping plates 6, fix the position between the clamping plates 54. When the hole is relatively large, pass two lifting brackets 5 through the inside of the hole respectively, then move the sliding seat 51 so that the sliding seats 51 on the left and right sides separate to both ends and fit against both ends of the hole respectively. Then expand and fix the clamping plates 54 at the ends of each sliding seat 51, so as to clamp workpieces of different sizes. Hook the fixture and the workpiece to a mobile device through the hook 3, and immerse the workpiece in the electrophoresis solution. When the workpiece is relatively light, the buoyancy of the electrophoresis solution will cause the workpiece to move upward, but the workpiece will not separate from the clamping plate 54, and the coverage area of the fixture on the workpiece surface is reduced. At the same time, the movable connection between the cross bracket 1 and the rotary hanging component can make the workpiece rotate in the electrophoresis tank, so that the coating covers the workpiece more evenly, reduces the area of the fixture covering the workpiece, prevents the workpiece from falling off the fixture, and makes the coating more uniform.
