Description

Technical Field

[0001] This utility model relates to the field of anodizing fixtures, specifically to a novel hard anodizing fixture. Background Technology

[0002] Hard anodizing is an electrochemical treatment technology that forms a thick and hard oxide film on the surface of aluminum and aluminum alloys. The oxide film has the characteristics of high hardness, good wear resistance, corrosion resistance and insulation, and is widely used in aerospace, machinery manufacturing, automotive industry and other fields.

[0003] Hard anodizing is essentially an electrolytic oxidation reaction. It uses aluminum or aluminum alloy as the anode and lead plate or the like as the cathode. In a specific acidic electrolyte (such as sulfuric acid, oxalic acid, chromic acid, etc.), an external direct current is applied to cause an oxidation reaction on the aluminum surface.

[0004] Traditional hangers typically have fixed spacing between their brackets, making it impossible to flexibly adjust according to workpiece dimensions (such as width and shape). This makes it difficult to meet the hanging requirements of irregularly shaped or multi-specification workpieces, resulting in a single hanger only being able to fit a few specific workpieces, which increases the frequency and cost of changing hangers during production.

[0005] Therefore, it is necessary to invent a new type of hard anodizing fixture to solve the above problems. Utility Model Content

[0006] The purpose of this invention is to provide a novel hard anodizing fixture. By setting multiple sets of slots on the inner wall of the adjusting component a and cooperating with the positioning posts on the outer side of the adjusting component b, the distance between the hanger a and the hanger b can be flexibly changed, enabling adaptation to workpieces of different widths and shapes, reducing the frequency of fixture replacement, and lowering production costs. This solves the problem in the prior art where the spacing between the hangers of traditional fixtures is fixed, making it impossible to flexibly adjust according to the workpiece size, and making it difficult to adapt to irregularly shaped and multi-specification workpieces, resulting in high replacement frequency and increased costs.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a novel hard anodized hanger, comprising...

[0008] A main frame is used to support the overall device. A hook is fixedly connected to the upper part of the main frame, and a support rod is fixedly installed on the outside of the hook.

[0009] An adjustment assembly is disposed on the outside of the support rod. The adjustment assembly includes an adjustment component a and an adjustment component b. The adjustment component a and the adjustment component b are sleeved on the outside of the support rod. A bracket a and a bracket b are respectively fixedly installed on the outside of the adjustment component a and the adjustment component b. A slot is opened on the inner wall of the adjustment component a near the adjustment component b. A positioning post is inserted into the inner wall of the slot. The positioning post is fixedly connected to the outside of the adjustment component b.

[0010] Preferably, multiple sets of adjusting member a and adjusting member b are provided. The adjusting member a has a plugging tooth on the side closer to the main frame, and the adjusting member b has a plugging groove on the inner wall of the side away from the main frame. The end of the support rod away from the main frame is fixedly installed with a fixing cap by bolts. The fixing cap is inserted into the outside of the plugging groove of the adjacent set of adjusting members b.

[0011] Preferably, multiple sets of slots are provided, and the multiple sets of slots are evenly provided on the inner wall of the adjusting member a.

[0012] Preferably, multiple sets of hanging brackets a and b are provided, and adjacent sets of hanging brackets a and b are staggered.

[0013] Preferably, the ends of the bracket a and bracket b are bent towards each other.

[0014] Preferably, the inner wall of the fixing cap is provided with a strip-shaped protrusion, which is inserted into the inner wall of the support rod.

[0015] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0016] In this utility model, the adjustment component a and adjustment component b can be adjusted in relative position through the cooperation of slots and positioning posts. Multiple sets of slots allow for flexible changes in the distance between hangers a and b, thus adapting to workpieces of different sizes and shapes. This solves the problem of poor adaptability to workpiece specifications in traditional hangers, reducing usage costs. The insertion teeth of adjustment component a cooperate with the insertion slots of adjacent adjustment component b, and the fixing cap is fixed to the end of the support rod by bolts and inserted into the outside of the insertion slot of adjustment component b. This securely connects multiple sets of adjustment components to the support rod, preventing loosening or displacement of the adjustment components during use. This modular assembly facilitates disassembly and maintenance. Attached Figure Description

[0024] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0025] This utility model provides, for example Figure 1 - Figure 3 The novel hard anodized mounting bracket shown includes a main frame 1 and an adjustment assembly 4;

[0026] The main frame 1 is used to support the overall device. The upper part of the main frame 1 is fixedly connected to the hook 2, which is directly hung on the external power supply or conductive busbar. It is the key component for connecting the hanger to the power supply, ensuring that the current is transmitted to the entire hanger and workpiece through the hook 2. By fixing it to the main frame 1, the suspension position of the hanger in the anodizing tank is determined, ensuring that the workpiece is in a reasonable area in the electrolyte. The outside of the hook 2 is fixedly installed with a support rod 3, which supports multiple sets of adjustment components a41 and b44, and at the same time evenly conducts the current transmitted from the hook 2 to each adjustment component 4 and the hanger.

[0027] Adjustment component 4 is located on the outside of support rod 3. Adjustment component 4 includes adjustment element a41 and adjustment element b44. The slot 42 on adjustment element a41 engages with the positioning post 43 of adjustment element b44, enabling detachable connection and angle adjustment, thereby changing the distance between adjacent hangers a5 and b6. Adjustment elements a41 and b44 are sleeved on the outside of support rod 3. Hangers a5 and b6 are fixedly installed on the outside of adjustment elements a41 and b44 respectively. The ends of hangers a5 and b6 are bent towards each other, directly contacting and suspending the workpiece. The bending structure at the ends ensures stable clamping of the workpiece, preventing it from falling off, and transmitting power from support rod 3. The current is transmitted to the workpiece to ensure that a uniform oxide film is formed on the workpiece during the anodizing process. The inner wall of the adjusting component a41 near the adjusting component b44 has a slot 42. Multiple sets of slots 42 are evenly distributed on the inner wall of the adjusting component a41. The multiple sets of evenly distributed slots 42 provide multiple insertion positions for the positioning post 43. It is the core structure for adjusting the spacing of the hangers and can adapt to workpieces of different widths or shapes. The positioning post 43 is inserted into the inner wall of the slot 42. By inserting it into different slots 42, the relative position of the adjusting component a41 and the adjusting component b44 is precisely controlled, so as to realize the flexible adjustment of the spacing between the hanger a5 and the hanger b6. The positioning post 43 is fixedly connected to the outside of the adjusting component b44.

[0028] like Figure 2 - Figure 4 As shown, multiple sets of adjusting components a41 and b44 are provided. Adjusting component a41 has a insertion tooth 45 on the side closer to the main frame 1, and adjusting component b44 has an insertion groove 46 on the inner wall of the side away from the main frame 1. By inserting the insertion groove 46 and the insertion tooth 45, the two adjacent sets of adjusting components a41 and b44 can be positioned. The end of the support rod 3 away from the main frame 1 is fixedly installed with a fixing cap 47 by bolts 48 to seal the end of the support rod 3 and prevent the adjusting components 4 from slipping off the support rod 3. The strip-shaped protrusion on the inner wall is inserted into the inner wall of the support rod 3 to enhance the connection with the support rod 3. At the same time, its outer side is inserted into the insertion groove 46 of the last adjusting component b44 to further fix the overall position of the multiple sets of adjusting components 4. The fixing cap 47 is inserted into the outer side of the insertion groove 46 of the adjacent set of adjusting components b44.

[0029] like Figure 2 and Figure 3 As shown, multiple sets of hangers a5 and hangers b6 are provided, with adjacent sets of hangers a5 and hangers b6 staggered, so that hangers a5 and hangers b6 are provided on both the front and rear sides of the support rod 3, which can clamp more workpieces. The inner wall of the fixing cap 47 is provided with strip-shaped protrusions, which are inserted into the inner wall of the support rod 3.

[0030] The working principle of this practical system is as follows: The main frame 1 serves as the core support structure. It is attached to the conductive busbar of the anodizing tank or an external suspension device via hooks 2 fixed at the top, thus determining the position of the hanger in the electrolyte. Hooks 2 also serve a conductive function, introducing current from the external power source into the hanger system, and achieving initial conduction and dispersion of the current through the support rods 3 fixed on the outside.

[0031] The adjustment assembly 4 is sleeved on the support rod 3 through the adjustment component a41 and the adjustment component b44. The outer brackets a5 and b6 of both directly contact and clamp the workpiece. The structure of the bracket ends bending towards each other can enhance the clamping force on the workpiece and prevent the workpiece from falling off under the impact of the electrolyte.

[0032] According to the workpiece size requirements, the fixing cap 47 is released by loosening the bolt 48. The fixing cap 47 is removed, and multiple sets of adjusting parts a41 and adjusting parts b44 are removed in sequence. Multiple sets of slots 42 on the inner wall of adjusting part a41 are matched with the positioning post 43 on the outer side of adjusting part b44. The angle between the two is adjusted by selecting different slots 42 positions, thereby changing the distance between the hanger a5 and the hanger b6, so as to adapt to workpieces of different widths and shapes.

[0033] Multiple sets of adjusting components a41 and b44 are connected by inserting teeth 45 and inserting slots 46 to form a modular combination. At the same time, it is ensured that the connection between adjacent components is stable and to prevent loosening. Then, the bolts 48 are tightened to fix the fixing cap 47. The strip-shaped protrusion on its inner wall is inserted into the inner wall of the support rod 3, and the outer side is embedded in the inserting slot 46 of the end adjusting component b44, locking the entire adjusting assembly 4 from the end to prevent the components from sliding or falling off during use. The whole device is made of titanium alloy, which has good conductivity and rigidity, ensuring efficient current transmission and structural stability.

[0034] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
