Description

Technical Field

[0001] This utility model relates to the field of clamping technology, and in particular to a spring clamp made of hard anodized aluminum alloy. Background Technology

[0002] Hard anodizing of aluminum alloys is an electrochemical surface treatment technology widely used in the production of aluminum alloy products. This is because the oxide film obtained by hard anodizing has superior performance compared to that obtained by general electrochemical anodizing methods. The main purpose of hard anodizing of aluminum alloys is to improve various properties of aluminum and aluminum alloys, including corrosion resistance, wear resistance, insulation, and adsorption properties. It is suitable for both wrought aluminum alloys and die-cast aluminum alloy parts.

[0003] During the anodizing process, aluminum alloy parts must withstand high voltage and current. Hard anodizing fixtures and other similar clamps and devices must maintain a firm and reliable contact with the parts and be able to withstand strong agitation of the solution to dissipate the large amount of heat generated during hard anodizing. While ensuring sufficient conductivity, the contact area should be minimized to ensure excellent contact between the fixture and the parts, preventing poor contact that could lead to excessive localized current, breakdown, or burning of the parts. Since the clamped area cannot form an oxide film, clamping marks will remain after oxidation. Therefore, it is crucial to ensure good conductivity while minimizing clamping marks.

[0004] like Figure 1 As shown, existing spring clamps use cylindrical helical springs to hold aluminum alloy parts. Because the spring spirals upward, it cannot guarantee the contact area of ​​the parts well, the conductivity is unstable, and it is easy to cause the parts to burn. Utility Model Content

[0005] To address the problems mentioned in the background section, this invention provides a spring clamp made of hard anodized aluminum alloy.

[0006] This utility model discloses the following technical solution: a spring clamp made of hard anodized aluminum alloy, including a bracket, a hook and a clamping plate. The bracket has a triangular structure, including a vertical rod and a horizontal rod. The vertical rod is set perpendicular to the horizontal rod. Diagonal rods are symmetrically arranged between the vertical rod and the horizontal rod. The vertical rod, the horizontal rod and the diagonal rods are welded together. The hook is welded to the end of the vertical rod away from the horizontal rod. The clamping plate is welded to both sides of the horizontal rod. The clamping plate has cylindrical rods at both ends. The clamping plate is made by stamping and bending and has elasticity.

[0007] Furthermore, there are several clips.

[0008] Furthermore, the cylindrical rods are arranged perpendicular to the length direction of the clamping piece, and the two cylindrical rods are parallel.

[0009] Furthermore, the hook shown is made of copper.

[0010] Furthermore, the cylindrical rod is made of copper and is welded to both ends of the clamp.

[0011] Beneficial effects: Compared with the prior art, the aluminum alloy hard anodized spring clamp of this utility model clamps the parts by setting clamping plates on the bracket. The bracket has a triangular structure, which has high stability. The clamping plates have cylindrical rods at both ends for clamping. When clamping, the cylindrical rods extend into the holes in the parts that do not need to be anodized, which can avoid leaving marks after anodizing and has good electrical conductivity.

[0017] like Figures 2 to 4 As shown, a spring clamp made of hard anodized aluminum alloy includes a bracket, a hook 1, and a clamping plate 2. The bracket has a triangular structure, including a vertical rod 3 and a horizontal rod 4. The vertical rod 3 is set perpendicular to the horizontal rod 4. Diagonal rods 5 are symmetrically arranged between the vertical rod 3 and the horizontal rod 4. The vertical rod 3, the horizontal rod 4, and the diagonal rods 5 are welded together as a whole, which is stable and reliable. The hook 1 is welded to the end of the vertical rod 3 away from the horizontal rod 4 and is used to hang the clamp and connect current. The clamping plate 2 is welded to both sides of the horizontal rod 4. The clamping plate 2 has cylindrical rods 6 at both ends for clamping aluminum alloy parts. The clamping plate 2 is made by stamping and bending, which has elasticity and can ensure clamping stability.

[0018] The clamping plates 2 are numerous and can simultaneously clamp multiple parts for oxidation treatment. The attached diagram shows six clamping plates 2, which can clamp six parts at the same time. The cylindrical rods 6 are arranged perpendicular to the length direction of the clamping plates 2, and the two cylindrical rods 6 are parallel. When clamping, the cylindrical rods 6 extend into the holes inside the parts that do not need to be oxidized. The axial distance between the two cylindrical rods 6 is greater than the distance between the two holes on the parts used for clamping. The elasticity of the clamping plates 2 is used to stably clamp the parts, and no marks are left on the surface of the parts after oxidation treatment. The hook 1 shown is made of copper and has good conductivity, which can ensure the stability of the current connected during oxidation treatment. The cylindrical rods 6 are made of copper and are welded to both ends of the clamping plates 2, ensuring stable clamping and stable current.

[0019] In use, the cylindrical rods 6 at both ends of the clamp 2 are inserted into the holes on the aluminum alloy parts. Because the clamp 2 is elastic, it can ensure that the parts are clamped stably. Several clamps 2 are set on the bracket to clamp multiple parts at the same time. After the parts are clamped, the hook 1 is used to hang the fixture and the parts into the anodized container. Then, the fixture is connected to the current. Since the hook 1 and the cylindrical rod 6 are both made of copper, they have good conductivity, which allows the parts to be connected to a stable current, effectively preventing damage to the parts and leaving no clamping marks.

[0020] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
