Abstract
Description
Technical Field
[0001] This application relates to the field of hanger technology, and more specifically, to a reversible electrophoretic coating hanger. Background Technology
[0002] Electrophoretic coating technology, due to its excellent coating uniformity, strong adhesion, and superior corrosion resistance, has been widely used in the surface treatment of metal workpieces such as automotive parts, construction machinery, and hardware. As a core component in the electrophoretic coating process, the fixture serves to support, fix, and conduct electricity; its structural design directly affects the coating quality, production efficiency, and production costs.
[0003] In actual production, traditional electrophoretic coating fixtures mostly adopt a fixed hook structure. After the workpiece is fixed by the hook, it is immersed in the electrophoretic bath. However, the part where the workpiece contacts the hook will form a coating dead corner. This area cannot fully contact the electrophoretic bath liquid, resulting in missing coating. It is necessary to manually recoat it later, which increases the labor intensity.
[0004] In view of this, we propose a flip-up electrophoretic coating fixture. Utility Model Content
[0005] The purpose of this application is to provide a flip-up electrophoretic coating hanger, which can effectively solve the problem in the prior art that the part of the workpiece in contact with the hook will form a coating dead corner.
[0006] This application provides a reversible electrophoretic coating hanger, including: A mouth-shaped hanging bracket, wherein the bottom of the mouth-shaped hanging bracket has multiple through holes, a fixing strip is fixedly connected to one side of the inner wall of the through holes, and a hook is fixedly connected to the bottom end of the fixing strip; The lifting plate is slidably connected to the other side of the inner wall of the through hole. The bottom end of the lifting plate is fixedly connected to a hook. The surface of the mouth-shaped bracket is provided with an alternating hook mechanism. The center of the top of the mouth-shaped bracket is rotatably connected to a connecting rod through a damping bearing. A structural stabilizing mechanism and a flipping positioning mechanism are provided between the connecting rod and the mouth-shaped bracket.
[0007] As an optional solution to the technical solution of this application, a sliding groove is provided on one side wall of the fixed plate, and a sliding strip is fixedly connected to one side wall of the lifting plate. The lifting plate is slidably connected to the fixed plate through the sliding strip and the sliding groove.
[0008] As an optional solution to the technical solution in this application, the alternating hook mechanism includes a connecting plate fixed to the top of multiple lifting strips, a screw threaded through one side of the connecting plate, and the bottom end of the screw rotatably connected to the inner wall of the orifice-shaped bracket.
[0009] As an optional solution to the technical solution of this application, the top end of the screw penetrates the inner wall of the orifice-shaped bracket and extends to its top, and is fixedly connected to a knob.
[0010] As an optional solution to the technical solution of this application, the structural stabilizing mechanism includes a rotating sleeve rotatably connected to the middle of the connecting rod, and the two side walls of the rotating sleeve are obliquely fixedly connected to the two sides of the top of the mouth-shaped bracket.
[0011] As an optional solution to the technical solution of this application, the flipping positioning mechanism includes an L-shaped block fixed to the bottom of one side wall of the connecting rod, and a magnetic block fixedly connected to the middle of the top of the mouth-shaped bracket. The L-shaped block and the magnetic block are magnetically connected to assist the mouth-shaped bracket in flipping 180 degrees.
[0012] One or more technical solutions provided in the embodiments of this application have at least the following technical effects or advantages: This application, by setting up fixed strips, lifting strips and corresponding hooks one and two, and cooperating with an alternating hooking mechanism composed of connecting plates, screws and knobs, can realize the alternating hooking of workpieces. This allows the original coating dead corners of the workpieces in contact with the hooks to be fully exposed to the electrophoresis tank liquid during the alternating process, completely solving the coating dead corner problem of traditional fixed hook hangers, avoiding subsequent manual touch-up coating, and effectively reducing labor intensity.
[0013] This application's orifice-shaped hanger is rotatably connected to the connecting rod via a damping bearing, ensuring a smooth and gentle flipping process and reducing impact damage to the workpiece and the hanger itself. The cooperation between the rotating sleeve and the inclined rod in the structural stabilization mechanism significantly improves the overall stability of the hanger, preventing swaying, deviation, or even workpiece detachment during flipping. The flipping positioning mechanism utilizes the magnetic connection between the L-shaped block and the magnetic block to precisely assist the orifice-shaped hanger in achieving 180-degree flipping positioning, ensuring consistency in the coating process. The cooperation between the slide bar and the slide groove ensures smooth sliding of the lifting plate, and the knob operation screw adjustment is convenient. The overall structural design is reasonable, highly practical, and effectively improves the quality and production efficiency of electrophoretic coating. Attached Figure Description

[0016] The present application will be further described in detail below with reference to the accompanying drawings.
[0017] Reference Figures 1-4 This application discloses a flip-up electrophoretic coating fixture, including a mouth-shaped bracket 1, which serves as the overall load-bearing frame of the fixture. It integrates components such as through holes 2, fixing strips 3, and lifting strips 5 to provide an installation base for each part. The bottom of the mouth-shaped bracket 1 has multiple through holes 2 for installing the fixing strips 3 and lifting strips 5. The fixing strips 3 are fixedly connected to one side of the inner wall of the through holes 2. The bottom end of the fixing strips 3 is fixedly connected to a hook 4 for initially hooking the workpiece to achieve the initial positioning of the workpiece. It works with the hook 6 to complete the alternating exposure of coating dead corners, providing a foundation for full coating. The lifting plate 5 can slide up and down to raise and lower the hook 2 6, and work with the hook 1 4 to complete the alternating clamping of the workpiece, so that the original dead corner part is released from clamping. The lifting plate 5 is slidably connected to the other side of the inner wall of the through hole 2. A groove 7 is opened on one side wall of the fixed plate 3. A slide bar 8 is fixedly connected to one side wall of the lifting plate 5. The lifting plate 5 is slidably connected to the fixed plate 3 through the slide bar 8 and the groove 7. The bottom end of the lifting plate 5 is fixedly connected to the hook 2 6, forming an alternating clamping combination with the hook 1 4. The surface of the mouth-shaped hanger 1 is provided with an alternating hook hanging mechanism 9. The center of the top of the mouth-shaped hanger 1 is rotatably connected to the connecting hanging rod 10 through a damping bearing to realize the overall suspension and fixation of the hanger. A structural stabilizing mechanism 11 and a flipping positioning mechanism 12 are provided between the connecting hanging rod 10 and the mouth-shaped hanger 1.
[0018] Reference Figures 1-4 The alternating hook mechanism 9 includes a connecting plate 91 fixed to the top of multiple lifting plates 5 to achieve synchronous lifting of multiple lifting plates 5 and ensure that all hooks 6 move in the same way. A screw 92 is threaded through one side of the connecting plate 91, which converts the rotational motion into the linear lifting motion of the connecting plate 91 through the thread transmission, so as to achieve precise height adjustment of the lifting plates 5. The bottom end of the screw 92 is rotatably connected to the inner wall of the mouth-shaped bracket 1, and the top end of the screw 92 penetrates the inner wall of the mouth-shaped bracket 1 and extends to its top, and is fixedly connected to a knob 93.
[0019] Reference Figures 1-4The structural stabilization mechanism 11 includes a rotating sleeve 111 rotatably connected to the middle of the connecting rod 10. The two side walls of the rotating sleeve 111 are obliquely fixedly connected to the two sides of the top of the mouth-shaped bracket 1 to prevent the mouth-shaped bracket 1 from shaking or shifting during the flipping process, avoid workpiece collision or falling off, and ensure the safety and stability of the coating process.
[0020] Reference Figures 1-4 The flipping and positioning mechanism 12 includes an L-shaped block 121 fixed to the bottom of one side wall of the connecting rod 10, and a magnetic block 122 fixedly connected to the middle of the top of the mouth-shaped bracket 1. The L-shaped block 121 and the magnetic block 122 are magnetically connected to assist the mouth-shaped bracket 1 in flipping 180 degrees, ensuring that the flipping angle is consistent each time, so that the coating posture of the workpiece is uniform.
[0021] In summary, the reversible electrophoretic coating fixture disclosed in this application, when in use, firstly, the workpiece is initially positioned by the hook 4 at the bottom of the fixed strip 3. Simultaneously, the lifting strip 5 slides with the sliding groove 7 on the fixed strip 3 via the slide bar 8, and its bottom hook 6, together with hook 4, clamps the workpiece. Rotating the knob 93 of the alternating hook mechanism 9 drives the screw 92 to rotate, converting the rotational motion into linear lifting of the connecting plate 91 via threaded transmission. This, in turn, causes multiple lifting strips 5 to slide synchronously, thus facilitating the spraying process. During this process, hook 4 and hook 6 are alternately hooked, so that the original dead corner of the workpiece is fully exposed to the electrophoresis tank liquid. The connecting rod 10 is rotatably connected to the mouth-shaped bracket 1 through the damping bearing, providing suspension support and smooth rotation conditions for the bracket to flip. When flipping, the rotating sleeve 111 of the structural stabilization mechanism 11 rotates with the mouth-shaped bracket 1 around the connecting rod 10. The two inclined rods 112 on both sides form a triangular stable support to prevent the mouth-shaped bracket 1 from shaking and deviating. When the mouth-shaped bracket 1 is flipped to 180 degrees, the L-shaped block 121 of the flipping positioning mechanism 12 and the magnetic block 122 at the top of the mouth-shaped bracket 1 are magnetically attracted to achieve precise positioning, ensuring that the flipping angle is consistent each time, and finally achieving all-round uniform electrophoretic coating of the workpiece.

Simple modifications or equivalent substitutions made by those skilled in the art to the technical solution of the present invention do not depart from the essence and scope of the technical solution of the present invention.
