Abstract
Description
Technical Field
[0001] The present application relates to the field of surface treatment, and in particular to an anodizing fixture for hole-shaped parts. Background Art
[0002] Dental implants (also known as artificial tooth roots) are surgically implanted into the alveolar bone of the toothless area. After they are combined with the alveolar bone, a device for repairing dentures is installed on top of them. After dental implants are implanted in the human body, long-term service in the body fluid environment will cause metal surface corrosion, and even allow metal ions to enter the body tissue and deteriorate the body tissue. In order to improve the biological cleanliness of medical titanium metal and promote its combination with human bone tissue, pure titanium implants need to be subjected to certain surface treatments after machining to change their biological properties; anodizing is a commonly used metal surface treatment technology used to improve the corrosion resistance, hardness and wear resistance of metals. It can clean the implant surface and significantly improve the bonding strength between dental implants and bones. During the anodizing process, a conductive bracket is required to support the metal parts to be processed and ensure that the current is evenly distributed.
[0003] The existing brackets and clamps are cast through the whole body, which is costly and not conducive to disassembly, maintenance and inspection. At the same time, the dental implant is very small and has holes on its parts, which makes it difficult to clamp it in conventional clamps. There may be some water stains or wear of the oxide film during disassembly, which seriously affects the oxidation efficiency. Utility Model Content
[0004] In order to improve the oxidation efficiency of parts, the present application provides an anodizing fixture for hole-shaped parts.
[0005] The present application provides an anodizing fixture for hole-shaped parts using the following technical solution:
[0006] An anodizing fixture for a hole-shaped component, comprising:
[0007] A clamp body, wherein the clamp body is provided with a raised mounting column, and a mounting hole is provided in the middle of the mounting column for mounting the clamp body on a bracket rod;
[0008] The clamp arm is fixedly connected to the clamp body, and comprises a first clamp arm and a second clamp arm symmetrically arranged with the first clamp arm. The first clamp arm and the second clamp arm clamp the part with a hole by penetrating into the hole of the dental implant.
[0009] By adopting the above technical solution, the clamp body is installed on the bracket through the mounting hole opened on the mounting column. The clamp body and the bracket are firmly nested, and it is convenient to maintain the height when multiple clamps are nested together to prevent collision of parts. The dental implant is clamped by inserting two symmetrically arranged clamp arms into the hole of the part with a hole, which facilitates the oxidation of the part with a hole, thereby improving the oxidation efficiency of the parts.
[0010] Preferably, a fixing hole is provided on the side of the mounting column, the fixing hole is a threaded hole, the fixing hole is perpendicular to the mounting hole, and the bracket rod is fixedly connected by a screw passing through the fixing hole.
[0011] By adopting the above technical solution, a fixing hole is opened on the side of the mounting column, and the bracket rod is connected by screws. The clamp can be stably connected to bracket rods of different models, and the clamp can be easily disassembled, inspected and replaced, thereby improving the oxidation efficiency of parts.
[0012] Preferably, the clamp body is configured as a disc structure, and a plurality of clamp arms are provided and are evenly arranged along the circumference of the clamp body.
[0013] By adopting the above technical solution, the clamp body is set to a disc structure, which is more conducive to the extension of the clamp arm, and can arrange as many clamp arms as possible to effectively utilize the space and improve the oxidation efficiency. The clamp arms are evenly arranged in the circumferential position of the clamp body to avoid the overall deviation of the clamp after the parts are placed. The surface treatment effect is more uniform, further improving the oxidation efficiency.
[0014] Preferably, a plurality of water flow openings are provided on the clamp body along the surface of the disc, and the water flow openings run through both ends of the clamp body.
[0015] By adopting the above technical solution, the fixture needs to be removed from the electrolyte after the anodizing of the dental implant is completed. By opening multiple water flow ports along the surface of the disc on the fixture body, the strength of the fixture body is maintained while facilitating the passage of liquid, which makes it easier for the operator to use.
[0016] Preferably, the length of the clamp arm is set to 0.8-1.2 times the diameter of the clamp body.
[0017] By adopting the above technical solution, the length of the clamp arm is set to 0.8-1.2 times the diameter of the clamp body. After the clamp arm is evenly fixed in the circumferential position of the clamp body, there is a certain distance between the ends of adjacent clamp arms, which can maintain the distance between adjacent components after installation and avoid collision between adjacent components. At the same time, the length of the clamp arm will not be too long to connect with the cathode plate or cathode grid, causing a short circuit.
[0018] Preferably, the first clamp arm and the second clamp arm can be divided into an arc segment and a straight segment, the arc segment is located at one end of the clamp arm close to the clamp body, and the straight segment is located at one end of the clamp arm away from the clamp body.
[0019] By adopting the above technical solution, the first clamp arm and the second clamp arm are divided into an arc segment close to the clamp body and a straight segment far away from the clamp body. When in use, the straight segments of the first clamp arm and the second clamp arm are inserted into the holes of the hole-shaped component. The arc segment is conducive to the uniform conduction of current between the clamp arm and the clamp body, and the straight segment is more conducive to the stable conduction of current, which makes it convenient for the clamp to conduct current to the dental implant, and can more evenly oxidize the surface of the dental implant, thereby improving the oxidation effect of the dental implant and further improving the oxidation efficiency.
[0020] Preferably, the straight sections of the first clamp arm and the second clamp arm extend away from each other.
[0021] By adopting the above technical solution, the straight sections of the first clamp arm and the second clamp arm extend in a direction away from each other, and there is a certain distance between the ends of the two clamp arms away from the clamp body. When the dental implant is assembled on the clamp arm, the ends of the two clamp arms are pressed hard, and the ends of the two clamp arms are inserted into the hole-shaped parts of the parts. Through the elastic properties between the two straight sections, the ends of the clamp arms and the part holes can be tightly combined in a small area to obtain a stable conductive current. After the parts are removed, they can be restored to their original state and reused, thereby further improving the oxidation efficiency of the parts.
[0022] Preferably, the length of the line connecting the two ends of the arc segment is equal to the length of the straight line segment.
[0023] By adopting the above technical solution, one end of the arc segment of the first clamp arm and the second clamp arm is fixed on the clamp body, and there is a distance between the other end points. When the parts are fixedly oxidized, the end of the straight segment is inserted into the part hole, and the length of the line connecting the two ends of the arc segment and the straight segment is set to be equal, which is convenient for relative pressing adjustment of the straight segment, and then convenient for installing the parts with holes on the clamp arms, further improving the oxidation efficiency of the parts.

[0031] The following is combined with Figure 1-2 This application is described in further detail.
[0032] The present application embodiment discloses an anodizing fixture for hole-shaped parts. Figure 1 The anodizing fixture for hole-shaped parts includes a fixture body 1 and a fixture arm 2. The fixture body 1 and the fixture arm 2 are both made of pure titanium material and have good electrical conductivity.
[0033] Reference Figure 1 The clamp body 1 is set in a disc shape, and a protruding installation column 11 is set on one side of the middle position. Specifically, a mounting hole 111 is opened in the center of the mounting column 11, and the clamp body 1 is sleeved on the bracket through the mounting hole 111.
[0034] A fixing hole 112 is provided on the side of the mounting column 11. The fixing hole 112 is perpendicular to the axis of the mounting hole 111 and penetrates from the outer side of the mounting column 11 and the inner wall of the mounting hole 111. The fixing hole 112 is a threaded hole. When the clamp body 1 and the bracket are installed, the bracket is first installed in the mounting hole 111, and then fastened and fixed by the screws set on the fixing hole 112. The clamp can be stably connected to bracket rods of different models, and the clamp is easy to disassemble, inspect and replace, thereby improving the oxidation efficiency of parts.
[0035] A water flow outlet 12 is provided on the clamp body 1. Specifically, the water flow outlet 12 is a through hole provided on the disc surface of the clamp body 1. Specifically, six water flow holes are provided, respectively, at the edge position of the clamp body 1 and at the mounting column 11 of the clamp body 1. Four of the water flow holes are provided at the circumferential edge position of the disc, and two are provided at the mounting column 11. After the anodizing of the dental implant is completed, the clamp needs to be removed from the electrolyte. By providing a plurality of water flow outlets 12 along the disc surface on the clamp body 1, the liquid can pass through while maintaining the strength of the clamp body 1, which saves the operator more effort when using it.
[0036] Reference Figure 2 The clamp arm 2 is divided into a first clamp arm 21 and a second clamp arm 22. Specifically, the clamp arm 2 is evenly arranged along the circumference of the clamp body 1 and is welded to the clamp body 1. The length of the clamp arm 2 is set to 0.8-1.2 times the diameter of the clamp body 1. In this embodiment, the length is set to be equal to the diameter of the clamp body 1. Multiple clamp arms 2 can be welded on each clamp body 1. In this embodiment, 30 clamp arms 2 are arranged along the circumference of the clamp body 1.
[0037] Specifically, the first clamp arm 21 and the second clamp arm 22 can be divided into an arc segment 211 and a straight segment 212. The arc segment 211 is fixedly connected to the clamp body 1, and the straight segment 212 is away from the clamp body 1, wherein the length of the line connecting the two ends of the arc segment 211 and the length of the straight segment 212 can be set to be equal, the arc surfaces of the arc segments 211 of the first clamp arm 21 and the second clamp arm 22 are arranged opposite to each other, and the two straight segments 212 extend in a direction away from each other, and there is a certain distance between the ends of the two clamp arms 2 away from the clamp body 1. When the dental implant is assembled on the clamp arm 2, the ends of the two clamp arms 2 are inserted into the hole-shaped part of the component by pressing hard. Through the elastic performance between the two straight segments 212, the ends of the clamp arms 2 and the component hole can achieve a small area of tight combination, obtain a stable conductive current, and can be restored to their original state after the component is removed, and can be reused, thereby further improving the oxidation efficiency of the component.
[0038] The implementation principle of the anodizing fixture for hole-shaped parts in the embodiment of the present application is as follows: the fixture body 1 is installed on the bracket through the mounting hole 111 opened on the mounting column 11, the fixture body 1 and the bracket are firmly nested, and it is convenient to maintain the height when multiple fixtures are nested together to prevent parts from colliding, and the dental implant is clamped by inserting two symmetrically arranged fixture arms 2 into the hole of the hole-shaped part, which facilitates the oxidation of the hole-shaped part, thereby improving the oxidation efficiency of the part.
[0039] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
