Description

Technical Field

[0001] This utility model belongs to the field of machining and relates to a flexible, non-marking fixture for anodizing flat parts, and more particularly to a non-marking clamping fixture for anodizing flat parts of various sizes. Background Technology

[0002] Currently, the aircraft manufacturing industry requires a large number of flat parts to undergo anodizing. Anodizing processes all require an anodizing bath. To ensure the stability of the anodizing bath solution and meet specifications, a series of performance tests, such as pitting corrosion, corrosion rate, corrosion resistance, and film weight, must be performed on the anodizing bath solution periodically / periodically. These performance tests all require test pieces. However, different projects and different performance tests have different requirements for the size of the test pieces. Currently, the clamping of flat parts and test pieces generally involves using aluminum clamps to hold one corner of the test piece, and then placing the clamp and test piece together into the bath solution. In reality, the test piece held by the clamp is being treated in a boiling, turbulent electrolyte solution. This clamping method leads to the following problems:

[0003] (1) Clamping one corner of the test piece will produce clamp marks on the surface of the test piece. The presence of clamp marks will reduce the quality of the film layer of the test piece, affect the accuracy of the test piece performance test, and thus affect the judgment of the bath performance results.

[0004] (2) The clamp marks produced on one corner of the test piece need to be repaired, which consumes a lot of operation time, seriously restricts production efficiency, and increases labor and material costs.

[0005] (3) When clamping one corner of the test piece, the current may be overheated due to poor contact, resulting in the test piece being scrapped and the anodizing experiment failing.

[0006] (4) Using paper clips to clamp flat parts or test pieces cannot guarantee that their surface orientation is uniform. As the parts or test pieces act as anodes during the anodizing process, they react with the cathode plate under the action of the electrolyte. Because the orientation of the parts or test pieces is not uniform, it cannot be guaranteed that their surface is parallel to the cathode plate, resulting in unstable product quality. Utility Model Content

[0007] This invention provides a flexible, non-marking fixture for anodizing flat parts. Through simple operation, the fixture can clamp the end face of the part or test piece, avoiding fixture marks on the surface and ensuring film quality. The fixture is suitable for both anodizing and chemical oxidation processes, meeting the clamping requirements of test pieces of various shapes and sizes. Operation is simple, reducing clamping and disassembly time and improving production efficiency.

[0008] The technical solution of this utility model:

[0009] A flexible, non-marking anodizing fixture for flat parts includes a hook 1, a frame 2, and a C-clamp 3.

[0010] The hook 1 is a U-shaped structure used to hook onto the conductive bar. To ensure good conductivity, the width of the U-shaped opening is the same as the width of the conductive bar.

[0011] The frame 2 includes columns and several crossbeams. The top of the column is fixedly connected to the hook 1. The column has a sliding track along its central axis. Each crossbeam has a sliding track along its central axis. The middle part of the crossbeam contacts the sliding track of the column and can slide up and down to adjust its position. The two are fixedly connected by bolts to achieve surface contact, which can ensure the full conductivity of the frame 2.

[0012] The C-clamp 3 is made of elastic metal material. The two ends of the C-clamp 3 are bent towards the middle, forming a triangular shape. A groove is made at the opening to clamp and fix the flat part, making the flat part parallel to the base plate of the C-clamp 3. The C-clamp 3 uses its own elasticity to adjust the size of the opening to accommodate flat parts of different sizes, and a certain distance is left between the opening of the C-clamp 3 and its base plate. An opening is made in the center of the base plate of the C-clamp 3, and a bolt is used to achieve surface contact and fixed connection with the crossbeam of the frame 2. Several C-clamps 3 are fixed on each crossbeam as needed, and the C-clamp 3 can slide left and right along the sliding track on the crossbeam to adjust its position.

[0013] Furthermore, the hook 1 is made of copper.

[0014] Furthermore, the frame 2 is made of aluminum alloy.

[0015] Furthermore, the C-shaped clip 3 is made of aluminum plate.

[0016] The beneficial effects of this utility model are:

[0017] ① Make full use of the characteristics of C-clamp T-material aluminum alloy. Due to the high plasticity of aluminum alloy, the opening angle on both sides of the C-clamp can be adjusted manually, so that the angle of the C-clamp can be quickly adjusted according to the size of the test piece, which can meet the clamping of test pieces of various specifications and sizes.

[0018] ②Use the grooves on both sides of the C-clamp to clamp the end face of the test piece, which effectively avoids clamp marks on the surface of the test piece, improves the quality of the test piece film, and reduces the rework operation for clamp marks on the surface of the test piece.

[0019] ③ The fixture is connected by bolts, with surface-to-surface contact. The C-clamp groove utilizes the height of the C-clamp to achieve a large contact area with the test piece, ensuring the overall conductivity of the fixture and the test piece. After clamping, the flat plate or test piece is oriented in a uniform manner, with its surface parallel to the cathode plate on the side wall of the tank, ensuring the quality of the surface film.

[0020] ④ This fixture utilizes the adjustable position of the crossbeam on the column, the adjustable position of the C-clamp on the crossbeam, and the easily adjustable opening size of the C-clamp to achieve flexible and adjustable clamping. It is suitable for clamping parts and test pieces of various sizes and has a wide range of applications. This fixture is simple to operate and reduces the labor intensity of workers.

[0021] ⑤ This fixture has a simple structure, is easy to manufacture, and is mostly made of aluminum alloy, resulting in low production and manufacturing costs. Attached Figure Description

[0030] The specific embodiments of this utility model are further described below with reference to the accompanying drawings and technical solutions. Example

[0031] A flexible, non-marking anodizing fixture for flat parts includes a hook 1, a frame 2, and a C-clamp 3.

[0032] like Figure 2 The hook 1 has a U-shaped structure and is made of copper. To ensure good conductivity, the width of the U-shaped opening is the same as the width of the conductive bar. The front end of the hook 1 is bent upward to facilitate the installation of the clamp on the conductive bar.

[0033] like Figure 1 and Figure 3The frame 2 is made of aluminum alloy and includes uprights and several crossbeams. The uprights are made of aluminum profiles to ensure the overall structural stability of the frame 2. Their tops are fixedly connected to hooks 1, and the uprights have sliding tracks along their central axis. The crossbeams are made of thick aluminum plates, and each crossbeam has a sliding track along its central axis. The middle of the crossbeam contacts the sliding track of the upright and can slide up and down to adjust its position. The two are fixedly connected by bolts to ensure sufficient electrical conductivity of the frame.

[0034] like Figures 4 to 6 The C-clamp 3 is made of T-material aluminum plate. The thickness of the aluminum plate ensures that the C-clamp 3 has a certain degree of elasticity and plasticity. The two ends of the C-clamp 3 are bent towards the middle, forming a triangular shape. A groove is made at the opening to clamp and fix the flat part, making the flat part parallel to the bottom plate of the C-clamp 3. The elasticity of the aluminum plate material allows the opening size to be adjusted to accommodate flat parts of different sizes. A certain distance is left between the opening of the C-clamp 3 and its bottom plate. An opening is made in the center of the bottom plate of the C-clamp 3, which is fixed to the crossbeam of the frame 2 by bolts to achieve surface contact. Several C-clamps 3 are fixed on each crossbeam as needed, and the C-clamp 3 can slide left and right along the sliding track on the crossbeam to adjust its position.

[0035] In use, the entire clamp is mounted on the conductive bar using hook 1, ensuring the uprights of frame 2 are vertical and parallel to the cathode plate 5 on the other side of the tank 4. Manually adjust the opening size of the C-clamp 3 according to the dimensions of the flat part being clamped, ensuring the maximum distance between the end grooves is slightly less than the width of the flat part. Utilizing the elasticity of the C-clamp 3 material, the flat part is held within the grooves, maintaining its parallelism to the cathode plate 5. This allows for clamping and fixing via the end face, effectively preventing clamp marks from forming on the surface of the flat part (see...). Figure 6 According to the actual size of the clamped parts, the position of the crossbeam on the column is adjusted by the sliding rail on the frame 2 column, and the position of the C-clamp 3 is adjusted by the sliding rail on the crossbeam. Alternatively, two or more C-clamps 3 can be used to clamp and fix the same flat part to ensure that the flat part is parallel to the cathode plate 5. The orientation of the clamped flat parts is uniform, ensuring that their surface is always parallel to the cathode plate on the side wall of the tank, and ensuring sufficient conductivity of the surface of the flat parts during the anodizing process (see...). Figure 7 ).

[0036] The above-described embodiments are merely illustrative of the implementation of this utility model, but should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
