Description

Technical Field

[0001] This utility model relates to the field of tooling and fixture technology, and in particular to a spring-loaded embossed single-point fixing and limiting hanger contact device. Background Technology

[0002] Existing workpiece electroplating fixtures often use hooks to suspend the workpiece directly. During the electroplating process, the workpiece will shake, making it difficult to ensure stability and easily causing deviations in the electroplating position.

[0003] The existing publication number CN219449924U discloses a spring-loaded hanger contact device, including a fixed rod installed on an electroplating hanger. The top of the fixed rod has a blocking part, and one side of the fixed rod has a spring-loaded part that works in conjunction with the blocking part. The blocking part includes a fixed ball seat installed on the fixed rod. A support rod 1 is installed on each side of the top of the fixed ball seat, and a support rod 2 is installed at the top of the support rod 1. A straight steel needle is installed at the top of the support rod 2. The spring-loaded part includes a spring-loaded connecting rod fixedly installed on one side of the fixed rod. The workpiece is fixed by the bending parts on the straight steel needle and the spring-loaded steel needle. The elasticity of the spring-loaded connecting rod drives the spring-loaded steel needle to engage with the bending part, pressing the workpiece against the straight steel needle. This improves the stability of the workpiece suspension, reduces the possibility of the workpiece falling off during suspension, and results in excellent electroplating performance, which is beneficial for the widespread adoption of the equipment.

[0004] However, although the aforementioned spring-loaded hanger contact device can grip the workpiece and conduct electricity to it, the lack of roughening treatment on the surface of the steel needle makes it prone to intermittent conductivity on the large surface of the round steel needle. Consequently, during the electroplating process, poor conductivity often leads to batch defects in the workpiece, causing some unnecessary losses to production. Utility Model Content

[0005] The purpose of this utility model is to provide a spring-loaded embossed single-point fixed limit hanger contact device, which solves the problem that the existing electroplating hanger steel needles often cause batch defects in the workpiece due to poor conductivity during the electroplating process, resulting in some unnecessary losses in production.

[0006] To achieve the above objectives, this utility model provides a spring-loaded embossed single-point fixing and limiting hanger contact device, comprising a first steel wire and a second steel wire;

[0007] The first steel wire and the second steel wire are clamped together, and the contact portion of the first steel wire and the second steel wire is flat and has a rough texture.

[0008] The first steel wire has a fixed limiting point, which is located on the side of the first steel wire closer to the second steel wire.

[0009] The first steel wire also has a movable limiting point, which is located on the side of the first steel wire near the second steel wire.

[0010] Both the first steel wire and the second steel wire are U-shaped steel wires.

[0011] Both the first and second steel wires are made of 316L steel wire.

[0012] This utility model discloses a spring-loaded embossed single-point fixing and limiting hanger contact device. In use, after pushing open the second steel wire, the product's pin is placed in the fixed limiting position of the first steel wire. After releasing the second steel wire, the first and second steel wires close together, clamping the workpiece. The contact portion of the first and second steel wires is flattened and hemp-patterned, resulting in a flat shape with the aforementioned rough texture. This transforms the large-area conductivity of the original round steel needle into multi-point small-area contact conductivity, fundamentally solving the problem of workpiece scrapping due to intermittent conductivity caused by large-area conductivity. With multi-point small-area contact conductivity, regardless of how the workpiece moves on the hanger contact, there will always be a contact point conducting electricity, effectively ensuring continuous conductivity during the electroplating process. Furthermore, the product is completely unaffected by force on the hanger contact, preventing deformation. Therefore, this spring-loaded embossed single-point fixing and limiting hanger contact device is simple to operate, provides effective conductivity, ensures a high product qualification rate after electroplating, and avoids production losses.

[0017] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0018] The first embodiment of this application is as follows:

[0019] Please see Figure 1 and Figure 2 ,in, Figure 1 This is a schematic diagram of the structure of the spring-loaded embossed single-point fixing and limiting hanger contact device according to the first embodiment of this utility model. Figure 2 This is a schematic diagram showing the positions of the fixed limiting point 104 and the movable limiting point 105 in the first embodiment of this utility model. This utility model provides a spring-loaded embossed single-point fixed limiting hanger contact device: including a first steel wire 101 and a second steel wire 102, wherein the first steel wire 101 has a fixed limiting point 104 and a movable limiting point 105.

[0020] In this specific embodiment, the first steel wire 101 and the second steel wire 102 are clamped together. The contact portions of the first steel wire 101 and the second steel wire 102 are flat and both have rough patterns 103. A special stamping die is used to flatten and emboss the contact portions of the first steel wire 101 and the second steel wire 102, making them flat and having the rough patterns 103. Because the surface of the steel needle is roughened, the conductivity changes from the large surface area of ​​the original round steel needle to multi-point small-surface contact conductivity. This fundamentally solves the problem of workpiece scrapping due to intermittent conductivity caused by large surface area conductivity. Multi-point small-surface contact conductivity ensures that there are always contact points conducting electricity regardless of how the workpiece moves on the hanger contact points, effectively guaranteeing continuous conductivity during the electroplating process.

[0021] The fixed limiting point 104 is located on the side of the first steel wire 101 closest to the second steel wire 102. The movable limiting point 105 is located on the side of the first steel wire 101 closest to the second steel wire 102. With a set of single-point limiting points and a set of movable limiting points 105 added to the first steel wire 101 at a fixed position, after the second steel wire 102 is pushed open, the product's pins are placed in the fixed limiting position of the first steel wire 101. The single-point limiting points and the movable limiting points 105 limit the product, ensuring that the product is completely unaffected by force at the hanger contact point and preventing deformation.

[0022] Secondly, both the first steel wire 101 and the second steel wire 102 are U-shaped steel wires. Both the first steel wire 101 and the second steel wire 102 are made of 316L grade steel wire. The second steel wire 102 can also be a straight steel wire, maintaining a straight state in the mechanical structure without additional limiting or adjusting mechanisms. Its main function is to provide a stable clamping force, cooperating with the first steel wire 101 to clamp the workpiece.

[0023] Using the spring-loaded embossed single-point fixed limiting hanger contact device of this embodiment, when in use, push open the second steel wire 102, place the product's pins at the fixed limiting position of the first steel wire 101, release the second steel wire 102, and the first steel wire 101 and the second steel wire 102 close together, clamping the workpiece. The contact portion of the first steel wire 101 and the second steel wire 102 is flattened and hemp-patterned, flattened with the rough texture 103. This changes the large-area conductivity of the original round steel needle to multi-point small-area contact conductivity, fundamentally solving the problem of workpiece scrapping due to intermittent conductivity caused by large-area conductivity. With multi-point small-area contact conductivity, no matter how the workpiece shakes on the hanger contact, there will always be contact points conducting electricity, effectively ensuring continuous conductivity during the electroplating process. Furthermore, the fixed limiting point 104 and the movable limiting point 105 limit the product, ensuring that it is completely free from force on the hanger contact and will not deform. Thus, the described elastic embossed single-point fixing and limiting hanger contact device is simple to operate, effectively conducts electricity, ensures the pass rate of electroplated products, and avoids production losses. Its working principle is simple, it is easy to manufacture, and product quality is guaranteed.

[0024] The above-disclosed embodiments are merely one or more preferred embodiments of this application and should not be construed as limiting the scope of this application. Those skilled in the art can understand that all or part of the processes for implementing the above embodiments and equivalent changes made in accordance with the claims of this application still fall within the scope of this application.
