Description

A dual-purpose electroplating fixture for both socketing and clamping Technical Field

[0001] This utility model relates to the field of electroplating fixture technology, specifically to an electroplating fixture that can be used for both socketing and clamping. Background Technology

[0002] In modern industrial production, electroplating is widely used in the field of metal surface treatment. It involves electrolysis to deposit a metal film onto the surface of metals or other materials, thereby preventing corrosion, improving wear resistance, and enhancing aesthetics. During the electroplating process, the electroplating rack, as a key component supporting the product to be plated, directly affects the electroplating quality and production efficiency through its fixtures.

[0003] Currently, there are two types of electroplating clamps on the market: one type is a clamp that holds and fixes the product on the outer side, which uses external clamping force to firmly fix the product on the hanger; the other type is a clamp that can extend into the product and hold and fix it on the inside, which uses internal support or clamping structure to position the product.

[0004] However, existing electroplating fixtures generally only have a single clamping and fixing method. When electroplating products with different structures and clamping requirements during the production process, it is necessary to frequently change different types of fixtures. This not only increases production preparation time and reduces production efficiency but also increases production costs. Furthermore, due to the lack of fixtures compatible with multiple clamping methods, a single clamping method may not be able to achieve stable fixation when handling products with complex structures, thus affecting the uniformity and quality consistency of the plating layer on the product surface during the electroplating process. Therefore, developing an electroplating fixture that can incorporate multiple clamping and fixing methods to meet diverse production needs has become an urgent technical problem to be solved in this field. Summary of the Invention

[0005] In view of the problems pointed out in the background art, this utility model proposes a dual-purpose electroplating fixture for both socketing and clamping to solve the above-mentioned technical problems.

[0006] The technical solution of this utility model is implemented as follows:

[0007] A dual-purpose electroplating fixture for both socketing and clamping includes an elongated connecting rod, one end of which is connected to a U-shaped elastic clamping part. The elastic clamping part is positioned with its opening facing away from the connecting rod. The elastic clamping part includes a middle connecting part and two side arms on the left and right, with the cross-sections of the two side arms arranged in a figure-eight shape.

[0008] The present invention is further configured such that the connecting rod is fixedly connected to the intermediate connecting part.

[0009] The present invention is further configured such that the elastic clamping part is made of metal wire.

[0010] The present invention is further configured such that the side arm is arranged in a wave-like undulation.

[0011] The present invention is further configured to include an elongated hanging rod, with the connecting rod fixedly connected to the hanging rod.

[0012] The present invention is further configured such that multiple connecting rods are provided and spaced apart along the length of the hanging rod, and connecting rods are provided on both sides of the hanging rod.

[0013] The present invention is further configured such that the length of the connecting rod on the same side gradually decreases from the middle to both ends.

[0014] The present invention is further configured to include an annular fixing frame, wherein the two ends of the hanging rod are respectively fixedly connected to the fixing frame.

[0015] The present invention is further configured to include a square frame-shaped bracket, with the fixing frame fixedly connected to both sides of the bracket.

[0016] By adopting the above technical solution, the beneficial effects of this utility model are as follows:

[0017] The dual-purpose electroplating fixture for both socketing and clamping provided by this utility model has two usage methods:

[0018] Method 1 involves clamping the bolt, with the bolt shank held between two side arms and the bolt head positioned above the two side arms, thus securing and fixing the bolt.

[0019] Method 2 involves fitting the tubular component into a sleeve, with the connecting rod and elastic clamping part extending into the tubular component. The front end of the tubular component is connected to the connecting rod, and the elastic clamping part clamps and fixes the rear end of the tubular component inside the tubular component.

[0029] 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.

[0030] The present invention will be described below with reference to Figures 1-6:

[0031] Example: A dual-purpose electroplating fixture for both socketing and clamping includes an elongated connecting rod 1. One end of the connecting rod 1 is connected to a U-shaped elastic clamping part 2. The elastic clamping part 2 is open facing away from the connecting rod 1 (forming an open structure that facilitates product installation). The elongated connecting rod 1 serves as the basic support component of the fixture, with one end connected to the U-shaped elastic clamping part 2. Its rod-like structure provides a stable connection and support for the entire fixture, ensuring the structural strength and stability of the fixture during the electroplating process.

[0032] The elastic clamping part 2 includes a central connecting part 21 and two side arms 22 on the left and right sides. The cross-section of the two side arms 22 is arranged in a V-shape. The central connecting part 21 is fixedly connected to the connecting rod 1 to realize the transmission of force and the stable combination of the structure. The two side arms 22 are the key components to realize the clamping function. Their cross-sections are arranged in a V-shape. This unique geometric design provides a mechanical basis for different clamping methods.

[0033] The elastic clamping part 2 is made of metal wire. This material has good elasticity and strength, which can meet the requirements of repeated clamping deformation while maintaining the reliability of the structure.

[0034] The side arms 22 are designed with a wave-like undulation.

[0035] The dual-purpose electroplating fixture for both socketing and clamping provided by this utility model has two usage methods:

[0036] In the first method of use, when clamping the bolt, the bolt shank is held by two side arms 22, with the bolt head located on the upper side of the two side arms 22. The side arms 22 are designed with a wavy, undulating shape, which significantly increases the contact area and friction with the bolt surface. From a mechanical perspective, the wavy structure forms multiple contact points, which can disperse the clamping force and avoid bolt surface damage caused by stress concentration at a single point. At the same time, the friction generated by multiple contact points works synergistically to effectively prevent the bolt from sliding or rotating during the electroplating process, thereby achieving stable clamping and fixing of the bolt and ensuring the positional accuracy and electroplating quality of the bolt during the electroplating process.

[0037] In the second method of use, when the tubular component is fitted, the connecting rod 1 and the elastic clamping part 2 extend into the interior of the tubular component. At this time, the front end of the tubular component abuts against the connecting rod 1, which provides axial positioning and support for the tubular component. The two side arms 22 of the elastic clamping part 2, with their V-shaped cross-section structure, form four contact points with the inner wall of the tubular component. These four contact points are evenly distributed, forming a stable four-point support structure. According to the principle of mechanical balance, this effectively limits the radial displacement and swaying of the tubular component. Simultaneously, the elastic clamping part 2, made of metal wire, has a certain deformation capacity, adapting to tubular components of different inner diameters. While ensuring clamping force, it avoids deformation of the tubular component due to over-clamping, thereby achieving stable clamping and fixing of the tubular component and ensuring the positional stability and plating uniformity of the tubular component during electroplating.

[0038] Through the aforementioned structural design and operating method, this electroplating fixture successfully combines both socketing and clamping clamping methods. In actual production, this dual-function feature effectively overcomes the limitations of traditional fixtures with only a single clamping method. Operators no longer need to frequently change different types of fixtures and can flexibly select the appropriate clamping method according to the structural characteristics of the product to be plated, significantly improving production efficiency and reducing production costs. Simultaneously, the diverse clamping methods can adapt to products of different shapes and structures, expanding the fixture's applicability and ensuring stable fixation and high-quality plating results for different types of products during the electroplating process. This demonstrates high practical value and market potential.

[0039] It also includes a long hanging rod 3, whose main function is to provide support and positioning for multiple connecting rods 1. The connecting rods 1 and the hanging rod 3 are fixedly connected. This ensures that there is no relative displacement between them during the electroplating process, thereby maintaining the stability of the entire fixture structure.

[0040] Multiple connecting rods 1 are provided and spaced apart along the length of the hanging rod 3, with connecting rods 1 on both sides of the hanging rod 3. This symmetrical distribution design effectively balances the overall force on the clamp and avoids structural tilting or deformation caused by excessive load on one side.

[0041] The length of connecting rod 1 on the same side gradually decreases from the middle to both ends. The different lengths of connecting rod 1 create a staggered distribution of products connected to the fixture. During the electroplating process, this staggered arrangement creates sufficient space between adjacent products, effectively avoiding problems such as poor flow of electroplating solution and mutual interference of plating layers caused by insufficient spacing between products. This ensures that the surface of each product can be evenly contacted with the electroplating solution, thereby improving the electroplating quality and the consistency of the plating layer.

[0042] It also includes a ring-shaped fixing frame 4, which is horizontally set, and the two ends of the hanging rod 3 are fixedly connected to the fixing frame 4 respectively.

[0043] It also includes a rectangular bracket 5, which is vertically positioned, and a fixing frame 4 is fixedly connected to both sides of the bracket 5. Multiple fixing frames 4 are provided and spaced apart vertically. This further increases the three-dimensional load-bearing capacity of the clamp.

[0044] The rectangular bracket 5 serves as the connection hub between the fixture system and the electroplating equipment, playing a crucial role in supporting the weight of the entire fixture system and transmitting electroplating process parameters. The bracket 5 is vertically positioned and fixedly connected to the horizontal fixed frame 4. This combination of vertical and horizontal structures forms a stable three-dimensional frame, providing reliable support for the entire fixture system.

[0045] Multiple fixed frames 4 are fixedly connected to both sides of the hanger 5 and are spaced apart in the vertical direction, allowing the hanger 5 to integrate the clamping unit composed of multiple fixed frames 4 and hanging rods 3 into a whole. In practical applications, the hanger 5 can be directly connected to the hoisting device of the electroplating equipment, suspending the entire clamping system in the electroplating tank. Its square frame structure not only facilitates connection and operation with the electroplating equipment but also enhances the structural strength of the hanger 5 itself to a certain extent, ensuring that it will not deform or be damaged during hoisting and electroplating, thereby guaranteeing the smooth progress of the entire electroplating operation.

[0046] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. 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.
