Description

Technical Field

[0001] This utility model belongs to the field of anodizing tooling fixtures for titanium alloy parts, specifically, it relates to an anodizing tooling for titanium alloy parts. Background Technology

[0002] During the anodizing process of titanium alloy parts, it is crucial to ensure effective and stable electrical conduction between the parts and the conductive anode rod, between the parts and the bath solution, and between the parts themselves. For complex-shaped titanium alloy parts, inappropriate mounting methods can lead to stacking, scratches on the film layer, and uneven film formation. Therefore, specialized tooling needs to be designed for titanium alloy parts with unique shapes. Currently, there is a type of anodized titanium alloy part, formed into a three-opening cylindrical shape through machining and welding. The current mounting method involves individually bundling titanium wires and suspending them from conductive copper rods. This method is inefficient, prone to poor conductivity, and makes it difficult to guarantee the surface condition of the parts. Utility Model Content

[0003] In view of the above-mentioned prior art, the purpose of this utility model is to overcome the shortcomings of the prior art, adapt to the needs of reality, and thus provide a titanium alloy parts anodizing assembly that effectively improves the conductivity between parts, effectively improves the clamping efficiency of workers, avoids uneven surface film and parts scratches caused by parts stacking, helps to improve parts production and delivery efficiency, reduce labor intensity, and can ensure the surface condition of the anodized film layer on the parts.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: an anodizing fixture for titanium alloy parts, including a hook, a support rod, and a clamp. One end of the hook is connected to the anode conductive copper rod, and the other end is connected to the top of the support rod. Multiple sets of clamps are provided, each set having two clamps. The multiple sets of clamps are equally spaced on the support rod, with the two clamps in the same set arranged symmetrically. The clamps are elastic and are supported on the inner wall of the part through their open ends.

[0005] Furthermore, the hook is welded to the support rod.

[0006] Furthermore, when welding the clamps to the support rod, multiple sets of clamps should maintain the same spacing, and the clamps should be set at an angle upward relative to the support rod during welding to prevent parts from falling due to gravity.

[0007] Furthermore, the hooks, supports, and clips are all made of TA2 titanium alloy.

[0008] Furthermore, the support rod is a slender, square rod, and its length is directly proportional to the effective liquid level height of the tank.

[0009] Furthermore, the clamp has a "V" shaped structure, and the clamp is welded to the support rod at the bottom and inserted into the inner cavity of the part through the two openings at the top.

[0010] Furthermore, the clamp is shaped like a scissor blade, wide at one end and gradually tapering to a point at the other. The clamp is welded to the support rod through the wide end and inserted into the inner cavity of the part through the pointed end.

[0011] Furthermore, the contact surface between the clamp and the inner wall of the part is an arc surface.

[0012] In this invention, to ensure the conductivity of the parts and prevent the introduction of foreign impurities into the anodizing bath, the entire tooling is made of TA2 titanium alloy. To prevent the parts from colliding with each other, the clamps are welded to the support rod at equal intervals according to the size of the parts. To prevent the parts from falling off, the clamps and support rod are at a certain upward angle during welding.

[0013] To ensure the structural strength and stability of the tooling, hooks, supports, and clamps are connected by welding. To prevent the tooling from scratching parts or injuring operators, there must be no burrs or other protrusions at the weld joints, the clamp tips must have smooth transitions, and the contact surface between the clamp and the inner wall of the part must be an arc. To facilitate part mounting, the clamps are shaped like the letter "V," and also resemble the blade of scissors, being wider at one end and gradually tapering to a point at the other. The hook dimensions are designed based on the diameter of the conductive copper rod.

[0014] This utility model is designed based on the shape and size characteristics of the parts, as well as the shape and size of the anodizing tank.

[0015] The beneficial effects of this utility model are as follows: The entire tooling is made of TA2 titanium alloy, and the hooks, support rods, and clamps are connected by welding to ensure the stability of the tooling. The hooks can be directly hung on the anode conductive copper rod to ensure the stability of conductivity. A large number of clamps are welded onto the support rod. The clamps are retracted and placed inside the part cavity. Relying on the outward elasticity of the titanium alloy clamps, the part is supported on the clamps, avoiding mutual contact between parts, improving the clamping efficiency of parts and the surface quality of parts after oxidation.

Example

[0022] like Figure 1As shown, this utility model provides an anodizing fixture for titanium alloy parts, including a hook 1, a support rod 2, and clamps 3. One end of the hook 1 is connected to the conductive copper rod, and the other end is welded to the top of the support rod 2. The size of the hook 1 is designed according to the diameter of the conductive copper rod. Multiple sets of clamps 3 are provided, with two clamps 3 in each set. The multiple sets of clamps 3 are welded around the support rod 2. To prevent the parts from contacting each other, a fixed distance is maintained between each set of clamps 3. During welding, the clamps 3 are set at a certain upward angle to the support rod 2 to prevent the parts from falling due to gravity. The two clamps 3 in the same set are symmetrically arranged. The clamps 3 are elastic and are supported on the inner wall of the part through their open ends, making contact with the part. For conductivity, hook 1, support rod 2, and clamp 3 are all made of TA2 titanium alloy. Support rod 2 is a slender quadrilateral rod. The length of support rod 2 is designed according to the effective liquid level of the tank. The higher the effective liquid level of the tank, the longer the support rod 2 is designed. The lower the effective liquid level of the tank, the shorter the support rod 2 is designed. Clamp 3 is shaped like the letter "V". Clamp 3 is welded to support rod 2 through the bottom of the "V" shape. It is inserted into the inner cavity of the part through the two openings at the top of the "V" shape. The contact surface between clamp 3 and the inner wall of the part is an arc surface. When clamp 3 is retracted into the inner cavity of the part, the part is supported on clamp 3 by the outward elasticity of titanium alloy clamp 3.

[0023] Preferably, the clip 3 is shaped like the blade of scissors, with one end wide and the other end gradually tapering to a point, which facilitates insertion into the inner cavity of the part. The clip 3 is welded to the support rod 2 through the wide end and inserted into the inner cavity of the part through the pointed end, with the end face of the pointed end rounded.

[0024] The working principle of this utility model is as follows: the hook 1 is connected to the conductive copper rod, and the clamp 3 is retracted and placed in the inner cavity of the part by external force. Relying on the outward elasticity of the titanium alloy clamp 3, the part is supported on the clamp 3. The clamp 3 and the support rod 2 are at a certain upward angle, so the part cannot fall out of the tank. During production, the current passes through the copper rod, hook 1, support rod 2, and clamp 3, and finally enters the part for anodizing treatment.

[0025] The manufacturing process of this utility model is as follows: ① Draw an anodizing drawing of a titanium alloy part to be manufactured; ② Process the material according to the shape and size drawn in the drawing; ③ After the material processing is completed, perform overall welding and local grinding.

[0026] The specific embodiments of this utility model have been described above. It should be understood that this utility model is not limited to the specific embodiments described above, and those skilled in the art can make various changes or modifications within the scope of the claims, which do not affect the substantive content of this utility model. Unless otherwise specified, the embodiments and features described in this application can be arbitrarily combined with each other.
