Description

Technical Field

[0001] This utility model relates to the field of electroplating hanger technology, and in particular to an electroplating hanger for automotive trim. Background Technology

[0002] In the automobile manufacturing process, electroplating of automotive trim strips is a crucial step in enhancing their aesthetics and durability. Electroplating is a surface treatment method that uses a salt solution containing a pre-plated metal as the cathode. Through electrolysis, the cations of the pre-plated metal in the plating solution are deposited on the surface of the base metal, forming a coating. Currently, electroplating workshops typically prepare general-purpose racks as well as special-purpose racks designed for specific parts. While general-purpose racks are diverse and suitable for various processes and parts, their applicability to parts with unique shapes and sizes, such as automotive trim strips, is somewhat limited.

[0003] Existing technologies, such as the utility model disclosed in publication number CN 207294923 U, disclose an electroplating fixture for automotive trim strips, including an electroplating bracket and two pairs of brackets vertically arranged on both sides of the electroplating bracket. In this utility model, the first and second bracket groups are symmetrical about a point on the electroplating bracket, which can meet the requirements of electroplating the spacing of automotive trim strips in a limited space, while also electroplating two pairs of automotive trim strips on the same side of the electroplating bracket, thereby improving electroplating efficiency and resource utilization.

[0004] When using the above technical solution,

[0005] (1) Poor versatility: Due to the fixed position and spacing of its hooks, it cannot adapt to different sizes and shapes of car trim strips. In actual production, car trim strips have various specifications. When encountering trim strips that are small in size or have special shapes, traditional hangers are difficult to fix effectively, causing the trim strips to shake or even fall off during the electroplating process, affecting the uniformity and stability of electroplating and reducing the product qualification rate.

[0006] (2) Inconvenient to fix: The overall structure of the hanger lacks a flexible adjustment mechanism, making it difficult for operators to hang the decorative strips according to actual production needs. Some decorative strips are difficult to hang due to their special shape and require clamping to fix them, which makes it difficult to carry out electroplating operations smoothly.

[0007] To address the aforementioned problems, this utility model provides an electroplating fixture for automotive trim strips. Utility Model Content

[0008] The purpose of this utility model is to solve the problems of poor universality and inconvenient fixing of existing car trim electroplating hangers, and to propose a car trim electroplating hanger.

[0009] To achieve the above objectives, the present invention adopts the following technical solution: an electroplating hanger for automotive trim, comprising a support frame, an adjustment and limiting mechanism, and an electroplating suspension mechanism. There are two support frames, with a connecting plate fixedly connected to the top of each support frame. The adjustment and limiting mechanism is threadedly connected to the interior of the support frame, and the electroplating suspension mechanism is threadedly connected to the outer surface of the adjustment and limiting mechanism. The adjustment and limiting mechanism includes a sliding slot formed in the support frame. A vertical sliding frame is slidably connected inside the sliding slot. A connecting ring is fixedly connected to the outer surface of the vertical sliding frame. Connecting holes are formed on both sides of the connecting ring. A rotating column is engaged inside the connecting ring. A limiting bolt is threadedly connected inside the connecting hole, and a limiting nut is threadedly connected to the outer surface of the limiting bolt.

[0010] Furthermore, the adjusting limiting mechanism includes threaded holes evenly spaced on both sides of the support frame, and the vertical sliding frame is threadedly connected to a limiting component through the inner wall of the limiting component. The vertical sliding frame is threadedly connected to the inside of the support frame through the limiting component.

[0011] Furthermore, the threaded holes and sliding slots are symmetrically arranged on both sides of the support frame, and a transverse support plate is fixedly connected to the outer surface of the rotating column. A transverse sliding hole is opened at the top of the transverse support plate, and the transverse support plate is threadedly connected to the inside of the connecting ring by a limiting bolt.

[0012] Furthermore, the electroplating suspension mechanism includes an adjustment hole opened at the top of the transverse support plate, a connector is threaded inside the adjustment hole, a transverse sliding frame is threaded on the outer surface of the connector, the transverse sliding frame is slidably connected inside the transverse sliding hole, and the transverse sliding frame is threaded to the top of the transverse support plate through the connector.

[0013] Furthermore, a connector is fixedly connected to one side of the horizontal sliding frame, a fixing rod is fixedly connected to the outer surface of the connector, and a bidirectional hook is fixedly connected to the outer surface of the fixing rod.

[0014] Furthermore, a clamping plate is fixedly connected to the other side of the horizontal sliding frame, a rotating shaft is rotatably connected inside the clamping plate, and a return spring is rotatably connected to the outer surface of the rotating shaft.

[0015] Furthermore, the adjusting limit mechanism and the electroplating suspension mechanism are symmetrically arranged inside the two support frames, and the bottom of the support frame is fixedly connected to an anti-slip base plate.

[0016] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0017] 1. In this utility model, the vertical sliding frame, horizontal sliding frame, and horizontal support plate enable multi-dimensional flexible adjustment of the hanger in the vertical, horizontal, and angular directions. Operators can quickly and accurately adjust the structure of the hanger according to the specific size and shape of the car trim, making it adaptable to various specifications of trim and significantly improving the hanger's versatility. By adjusting the position of the horizontal sliding frame, the distance between the bidirectional hook and the clamping plate is reduced, achieving a firm fixation. For trim with a certain curvature angle, the placement angle of the trim can be adjusted by rotating the horizontal support plate to ensure a uniform electroplating effect. This multi-dimensional flexible adjustment function reduces the time and cost waste caused by changing the hanger and improves production efficiency.

[0018] 2. In this utility model, the car trim strip is fixed from multiple directions by setting up a two-way hook, a clamping plate, and a return spring, ensuring the stability of the trim strip during the electroplating process. Even in complex environments such as the flow of electroplating solution, the trim strip will not shake or fall off. The two-way hook provides suspension support in two directions, and the clamping plate fits tightly against the surface of the trim strip under the action of the return spring, further enhancing the fixing effect. It can be flexibly adjusted to adapt to various specifications of car trim strips, while providing a convenient and stable fixing method, improving the stability of the electroplating process and product quality.

[0027] Please see Figure 1-6 This utility model provides a technical solution: an electroplating hanger for automotive trim, including a support frame 1, an adjustment limiting mechanism 2, and an electroplating suspension mechanism 3. There are two support frames 1, and a connecting plate 4 is fixedly connected to the top of the two support frames 1. The adjustment limiting mechanism 2 is threadedly connected to the inside of the support frame 1, and the electroplating suspension mechanism 3 is threadedly connected to the outer surface of the adjustment limiting mechanism 2.

[0028] The following section will explain the specific settings and functions of the adjustment limit mechanism 2 and the electroplating suspension mechanism 3.

[0029] In this embodiment: the adjusting limit mechanism 2 includes a sliding hole groove 21 opened in the support frame 1, a vertical sliding frame 22 is slidably connected inside the sliding hole groove 21, a connecting ring 23 is fixedly connected to the outer surface of the vertical sliding frame 22, connecting holes 24 are opened on both sides of the connecting ring 23, a rotating column 25 is snapped inside the connecting ring 23, a limit bolt 26 is threaded inside the connecting hole 24, and a limit nut 27 is threaded on the outer surface of the limit bolt 26.

[0030] The effect achieved by the above components is as follows: the rotating column 25 can rotate within the connecting ring 23, thereby driving the transverse support plate 210, which is fixedly connected to the rotating column 25, to adjust its angle. Tightening the limiting bolt 26 and the limiting nut 27 makes them fit tightly against the surfaces of the connecting ring 23 and the rotating column 25, thereby fixing the angle of the rotating column 25 and ensuring that the transverse support plate 210 will not shift in angle during the electroplating process. This ensures that the automotive trim can be electroplated at the optimal angle, improving the uniformity of the electroplating effect.

[0031] Specifically, the adjusting limit mechanism 2 includes threaded holes 28 evenly spaced on both sides of the support frame 1, and the vertical sliding frame 22 is threadedly connected to the inner wall of the limit member 29, and the vertical sliding frame 22 is threadedly connected to the inside of the support frame 1 through the limit member 29.

[0032] The effect achieved by the above components is as follows: the vertical sliding frame 22 can move freely in the vertical direction along the sliding groove 21. When the vertical sliding frame 22 slides to the required height in the sliding groove 21, the limiting member 29 is screwed into the corresponding threaded hole 28. The end of the limiting member 29 is tightly abutted against the inner wall of the support frame 1, thereby providing additional fixed support for the vertical sliding frame 22, preventing it from sliding up and down, and thus ensuring that the car trim installed on it is always in a stable electroplating position, ensuring the electroplating quality.

[0033] Specifically, the threaded hole 28 and the sliding groove 21 are symmetrically arranged on both sides of the support frame 1. A transverse support plate 210 is fixedly connected to the outer surface of the rotating column 25. A transverse sliding hole 211 is opened on the top of the transverse support plate 210. The transverse support plate 210 is threadedly connected to the inside of the connecting ring 23 by a limiting bolt 26.

[0034] The aforementioned components achieve the following effect: ensuring the uniformity of force distribution on the adjusting limit mechanism 2 during operation. During the sliding and fixing process, the supporting force and friction force on both sides of the vertical sliding frame 22 are evenly distributed, making the lifting and lowering of the vertical sliding frame 22 more stable and reliable, reducing problems such as jamming and tilting caused by uneven force distribution.

[0035] Specifically, the electroplating suspension mechanism 3 includes an adjustment hole 31 opened at the top of the transverse support plate 210. A connector 32 is threadedly connected inside the adjustment hole 31. A transverse sliding frame 33 is threadedly connected to the outer surface of the connector 32. The transverse sliding frame 33 is slidably connected inside the transverse sliding hole 211. The transverse sliding frame 33 is threadedly connected to the top of the transverse support plate 210 through the connector 32.

[0036] The effect achieved by the above components is that the electroplating suspension mechanism 3 can be flexibly adjusted in the lateral direction, so as to precisely adjust the position of the lateral sliding frame 33 according to the width and length of the car trim strip and the requirements for the spacing between the trim strips during the electroplating process.

[0037] Specifically, a connector 34 is fixedly connected to one side of the horizontal sliding frame 33, a fixing rod 35 is fixedly connected to the outer surface of the connector 34, and a two-way hook 36 is fixedly connected to the outer surface of the fixing rod 35.

[0038] The effect achieved by the above components is that the two-way hook 36 can suspend and fix the car trim strip from two different directions, which greatly enhances the fixation and ensures that the trim strip can be stably kept in the original position in the electroplating solution, thus ensuring the smooth progress of the electroplating process and the stability of the electroplating quality.

[0039] Specifically, a clamping plate 37 is fixedly connected to the other side of the horizontal sliding frame 33, a rotating shaft 38 is rotatably connected inside the clamping plate 37, and a return spring 39 is rotatably connected to the outer surface of the rotating shaft 38.

[0040] The aforementioned components achieve the following effect: When it is necessary to fix the automotive trim strip, the trim strip is placed between the clamping plate 37 and the bidirectional hook 36. The trim strip pushes the clamping plate 37 to rotate around the rotating shaft 38, compressing the return spring 39. Under the elastic force of the return spring 39, the clamping plate 37 automatically clamps the trim strip, forming a tight clamping and fixing of the trim strip, providing sufficient friction and clamping force to ensure that the trim strip will not slip or fall off during the electroplating process, thus improving the fixing effect and electroplating quality of special trim strips.

[0041] Specifically, the adjusting limit mechanism 2 and the electroplating suspension mechanism 3 are symmetrically arranged inside the two support frames 1, and the bottom of the support frame 1 is fixedly connected to an anti-slip base plate 5.

[0042] The effects achieved by the above components are as follows: the symmetrical structure makes the entire hanger more evenly stressed and more stable and reliable when carrying the car trim for electroplating, reducing shaking or tilting caused by uneven stress, thus providing a more stable electroplating environment for the car trim; the anti-slip base plate 5 can effectively increase the friction between the hanger and the placement surface, preventing the hanger from sliding or shifting during placement or operation, and improving operational safety.

[0043] Working principle: When using this car trim electroplating hanger, firstly, adjust the limiting mechanism 2 according to the size and shape of the car trim. Adjust the vertical sliding frame 22 to a suitable height by sliding it up and down in the sliding hole groove 21. Then, screw the limiting part 29 into the corresponding threaded hole 28 to fix the height position of the vertical sliding frame 22. Next, according to the tilt angle or bending shape of the trim, loosen the limiting bolt 26 and the limiting nut 27, rotate the rotating column 25 to drive the horizontal support plate 210 to adjust to a suitable angle, and then tighten the limiting bolt 26 and the limiting nut 27 again to fix the angle of the horizontal support plate 210.

[0044] After adjusting the limiting mechanism 2, the electroplating suspension mechanism 3 is adjusted. According to the width and length of the car trim, the connector 32 is rotated so that the lateral sliding frame 33 slides to a suitable lateral position in the lateral sliding hole 211 to ensure that the distance between the bidirectional hook 36 and the clamping plate 37 can match the size of the trim. Then, the car trim is placed between the bidirectional hook 36 and the clamping plate 37. The trim pushes the clamping plate 37 to rotate around the rotating shaft 38, and the return spring 39 is compressed. Under the elastic force of the return spring 39, the clamping plate 37 tightly clamps the trim, and at the same time, the bidirectional hook 36 hooks the trim from two directions to achieve a firm fixation of the car trim.

[0045] During the electroplating process, due to the symmetrical arrangement of the adjusting limit mechanism 2 and the electroplating suspension mechanism 3, as well as the function of the anti-slip base plate 5, the hanger can remain stable and avoid shaking or displacement. Even in complex environments such as the flow of electroplating solution, the car trim can be stably fixed on the hanger, ensuring the smooth progress of the electroplating process and allowing metal ions to be uniformly deposited on the surface of the car trim, thereby obtaining a high-quality electroplating effect.
