Description

Technical Field

[0001] This utility model belongs to the field of material surface treatment technology, and more specifically, it relates to an oxidation device for aluminum alloy parts. Background Technology

[0002] An aluminum alloy oxidation device is a specialized equipment for treating the surface of aluminum alloys. Its main purpose is to form a dense oxide film on the surface of the aluminum alloy. This oxide film can significantly improve the corrosion resistance, wear resistance, and decorative properties of aluminum alloy products. Existing aluminum alloy oxidation devices typically use anodizing methods. In this process, the aluminum alloy part is fixed on a special rack as the anode, then immersed in a solution containing a specific electrolyte, and a direct current is applied. The current passes through the electrolyte, triggering a chemical reaction on the aluminum alloy surface to generate a protective aluminum oxide film.

[0003] Based on the above, in the existing aluminum alloy anodizing equipment, due to the long-term standing of the electrolyte, the effective components are prone to sink to the bottom, resulting in uneven distribution of electrolyte components. Uneven electrolyte will directly affect the surface oxidation effect of aluminum alloy parts, making the formation speed and quality of oxide film unstable, and may lead to local insufficient or excessive oxidation. Utility Model Content

[0004] To address the aforementioned technical problems, this utility model provides an aluminum alloy parts oxidation device to solve the problem that in existing aluminum alloy parts oxidation devices, prolonged static storage of the electrolyte during the anodizing process leads to the sedimentation of effective components, resulting in uneven electrolyte distribution and thus affecting the oxidation effect of the aluminum alloy parts.

[0005] The purpose and effect of this utility model's aluminum alloy oxidation device are achieved through the following specific technical means:

[0014] An aluminum alloy component hanger, wherein the aluminum alloy component hanger is a strip structure and is installed below the cantilever of the hanger;

[0015] The bracket support column is a square tube structure, and the bracket support column is set at the front and rear below the aluminum alloy bracket.

[0016] Hanging fastening rod, wherein the hanging fastening rod is fixedly installed between the crossbeams of the hanging bracket;

[0017] A reciprocating rotary assembly, wherein the reciprocating rotary assembly is disposed inside the gear set housing;

[0018] A mounting bracket fixing assembly is disposed at the mounting bracket.

[0019] Furthermore, the reciprocating rotary assembly includes:

[0020] The first worm gear is concentrically fixedly connected to the output end of the reciprocating drive motor;

[0021] The second worm gear meshes above the first worm, and the first worm and the second worm gear together constitute a worm gear transmission mechanism.

[0022] Furthermore, the reciprocating rotary assembly also includes:

[0023] A reciprocating incomplete gear, wherein the reciprocating incomplete gear is an incomplete gear structure, and the reciprocating incomplete gear is concentrically fixedly connected to the rear of the second worm gear;

[0024] The reciprocating double rack is a ring-shaped structure with teeth on its inner wall. The teeth on the left and right inner walls of the reciprocating double rack mesh with the teeth of the reciprocating incomplete gear. The reciprocating incomplete gear and the reciprocating double rack together constitute a gear and rack reciprocating mechanism.

[0025] Furthermore, the reciprocating rotary assembly also includes:

[0026] A rotary drive screw, wherein the rotary drive screw is a screw structure, and the lower end of the rotary drive screw is fixedly installed at the bottom of the electrolyte tank;

[0027] A rotary driven sleeve is a cylindrical structure with threads on its inner wall. The rotary driven sleeve is rotatably connected to the lower end of the cantilever arm of the bracket. The rotary drive screw and the rotary driven sleeve together form a screw-nut transmission mechanism, and the thread engagement between the rotary drive screw and the rotary driven sleeve does not constitute a self-locking mechanism.

[0028] Furthermore, the bracket fixing assembly includes:

[0029] The hanging pin holes are block-shaped structures with rectangular through holes, and there are four of them. The four hanging pin holes are set in pairs on the two crossbeams of the hanging bracket.

Once the hand is released, the built-in spring will automatically return the pin hole and pin to the locking position to lock the bracket, ensuring the stability and convenience of operation. Even if the bracket is in reciprocating motion, it will not easily come off the lock, reducing the risk of the bracket falling off.

[0036] Then, thanks to the reciprocating rotation and hanging bracket fixing components mentioned above, the position of the aluminum alloy parts remains very stable throughout the oxidation process. This means that each part will undergo the same processing conditions, ultimately achieving a consistent oxidation effect. This not only enhances the product's appearance, such as the consistency of color and gloss, but also ensures the corrosion resistance and hardness of the aluminum alloy parts.

[0037] This invention features a reciprocating rotating component, enabling aluminum alloy parts to not only move up and down but also rotate synchronously in the electrolyte. This stirring-like motion ensures that each aluminum alloy part is fully in contact with the electrolyte, significantly accelerating the oxidation process and resulting in a more uniform oxide layer. Simultaneously, the device is equipped with a convenient hanging bracket fixing system; users can quickly lock or release the bracket simply by inserting a pin into the pin hole. Upon release, the built-in spring automatically locks the bracket, maintaining its stability even during dynamic handling and significantly reducing the risk of accidental bracket detachment.

[0045] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0046] Example 1:

[0047] As attached Figure 1 To be continued Figure 5 As shown:

[0048] This utility model provides an aluminum alloy parts oxidation device, comprising:

[0049] Electrolyte tank 10, which has a rectangular box-shaped structure;

[0050] The gear set housing 11 is a block structure with a rectangular through hole, and the gear set housing 11 is fixedly installed on the upper end of the front end face of the electrolyte tank 10.

[0051] A reciprocating drive motor 12 is fixedly mounted on the left end face of the gear set housing 11;

[0052] Hanging bracket 13 is a square tube bracket frame structure with two square tube beams inside the frame. Hanging bracket 13 is set above electrolyte tank 10.

[0053] Spring limiting block 14, there are two spring limiting blocks 14 in a block structure, and the two spring limiting blocks 14 are set on the upper end face of the two crossbeams of the hanging bracket 13.

[0054] Hanger cantilever 15, hanger cantilever 15 is a cross-shaped cylindrical structure;

[0055] Hanger handle 16, hanger handle 16 is located at the upper end of hanger cantilever 15;

[0056] Aluminum alloy bracket 17, which is a strip structure, is located below bracket cantilever 15.

[0057] The bracket support column 18 is a square tube structure, and the bracket support column 18 is set at the front and rear below the aluminum alloy bracket 17.

[0058] Hanger locking rod 19 is fixedly installed between the crossbeams of the hanger bracket 13;

[0059] A reciprocating rotary assembly is disposed inside the gear set housing 11;

[0060] Hanger fixing component, the hanger fixing component is set at the hanger bracket 13.

[0061] The reciprocating rotary component includes:

[0062] The first worm gear 1 is concentrically fixedly connected to the output end of the reciprocating drive motor 12;

[0063] The second worm gear 2 meshes above the first worm 1. The first worm 1 and the second worm gear 2 together constitute a worm gear transmission mechanism. In use, the reciprocating drive motor 12 is started to drive the first worm 1 to rotate. Since the first worm 1 and the second worm gear 2 together constitute a worm gear transmission mechanism, the second worm gear 2 rotates. Its function is to transmit the rotation of the reciprocating drive motor 12 to the rotation of the second worm gear 2, and at the same time, make the component have a self-locking characteristic.

[0064] The reciprocating rotary component also includes:

[0065] The reciprocating incomplete gear 3 is an incomplete gear structure and is concentrically fixedly connected to the rear of the second worm gear 2.

[0066] The reciprocating double rack 4 is an annular structure with teeth on its inner wall. The teeth on the left and right inner walls of the reciprocating double rack 4 mesh with the teeth of the reciprocating incomplete gear 3. The reciprocating incomplete gear 3 and the reciprocating double rack 4 together form a gear and rack reciprocating mechanism. In use, the rotation of the second worm gear 2 drives the rotation of the reciprocating incomplete gear 3. Since the reciprocating incomplete gear 3 and the reciprocating double rack 4 together form a gear and rack reciprocating mechanism, the reciprocating double rack 4 drives the support column 18 and then drives the hanging bracket 13 to move up and down reciprocatingly. Its function is to transmit the rotation of the second worm gear 2 to the up and down reciprocating motion of the hanging bracket 13, so that the aluminum alloy parts can move up and down reciprocatingly in the electrolytic cell, thereby increasing the oxidation efficiency.

[0067] The reciprocating rotary component also includes:

[0068] The rotary drive screw 5 is a screw structure, and its lower end is fixedly installed at the bottom of the electrolyte tank 10.

[0069] The driven sleeve 6 is a cylindrical structure with threads on its inner wall. It is rotatably connected to the lower end of the cantilever arm 15. The driven screw 5 and the driven sleeve 6 together form a screw-nut transmission mechanism, and the thread engagement between the driven screw 5 and the driven sleeve 6 does not constitute a self-locking mechanism. In use, the reciprocating motion of the bracket 13 drives the cantilever arm 15 to move up and down, which in turn drives the driven sleeve 6 to move up and down. Since the driven screw 5 and the driven sleeve 6 together form a screw-nut transmission mechanism and the thread engagement between the driven screw 5 and the driven sleeve 6 does not constitute a self-locking mechanism, the reciprocating motion of the driven sleeve 6 can simultaneously drive the aluminum alloy bracket 17 to reciprocate. Its function is to further transmit the reciprocating motion of the bracket 13 to the aluminum alloy bracket 17, which drives the aluminum alloy parts to reciprocate, thereby further improving the oxidation efficiency.

[0070] The mounting bracket fixing components include:

[0071] The four hanging pin holes 7 are block structures with rectangular through holes. The four hanging pin holes 7 are set in pairs on the two crossbeams of the hanging bracket 13.

[0072] The hanging bracket fixing pin 8 consists of two rectangular columnar structures. The two hanging bracket fixing pins 8 are located at the left and right ends of the hanging bracket locking rod 19. The two hanging bracket fixing pins 8 are respectively inserted into the rectangular through holes 7 formed by two pairs of hanging bracket fixing pin holes 7. In use, pulling the hanging bracket locking rod 19 causes the hanging bracket fixing pins 8 to move in the opposite direction, thereby releasing the locking between the two hanging bracket fixing pin holes 7. Its function is to enable the hanging bracket fixing pins 8 to lock and unlock the hanging bracket cantilever 15.

[0073] The mounting bracket also includes:

[0074] There are two pin return springs 9, which are set between the spring limit block 14 and the hanging part fixing pin block 8. In use, when the aluminum alloy hanging bracket 17 needs to be placed in the electrolyte tank 10, the hanging part locking rod 19 is pulled to move the hanging part fixing pin block 8 to the right, which makes a gap between the two hanging part fixing pin holes 7. The hanging bracket cantilever 15 is placed into the gap. Since the pin return spring 9 is a compression spring with a rebound force, the hanging part locking rod 19 is driven by the rebound force of the pin return spring 9 to reset the hanging part fixing pin block 8 and re-insert it into the rectangular hole of the hanging part fixing pin hole 7. Its function is to enable the hanging bracket cantilever 15 to achieve automatic release and locking function. At the same time, the elasticity of the pin return spring 9 makes the locking more stable.

[0075] The specific usage and function of this first embodiment are as follows:

[0076] In use, the reciprocating drive motor 12 is started, driving the first worm 1 to rotate. Since the first worm 1 and the second worm wheel 2 together form a worm gear transmission mechanism, the second worm wheel 2 rotates. Its function is to transmit the rotation of the reciprocating drive motor 12 to the rotation of the second worm wheel 2, while also giving the assembly a self-locking characteristic. The rotation of the second worm wheel 2 drives the reciprocating incomplete gear 3 to rotate. Since the reciprocating incomplete gear 3 and the reciprocating double rack 4 together form a gear and rack reciprocating mechanism, the reciprocating double rack 4 drives the bracket support column 18, which in turn drives the hanging component support. The bracket 13 reciprocates up and down, its function being to transmit the rotation of the second worm gear 2 to the up and down reciprocating motion of the bracket 13, allowing the aluminum alloy parts to move up and down in the electrolytic cell, increasing oxidation efficiency. The up and down reciprocating motion of the bracket 13 drives the bracket cantilever 15 to move up and down, which in turn drives the rotating driven sleeve 6 to move up and down. Since the rotating drive screw 5 and the rotating driven sleeve 6 share a screw-nut transmission mechanism and the thread engagement between the rotating drive screw 5 and the rotating driven sleeve 6 does not constitute self-locking, this allows the rotating driven sleeve 6 to move up and down... Simultaneously, it can drive the aluminum alloy bracket 17 to reciprocate, which further transmits the up-and-down reciprocating motion of the bracket 13 to the aluminum alloy bracket 17 driving the aluminum alloy parts to reciprocate, thus further improving the oxidation efficiency. Pulling the bracket locking rod 19 drives the bracket fixing pin 8 to move, thereby removing the locking mechanism between the two bracket fixing pin holes 7. This allows the bracket fixing pin 8 to lock and unlock the bracket cantilever 15. When it is necessary to place the aluminum alloy bracket 17 on an electric... When the device is inside the liquid tank 10, pulling the hanging locking lever 19 causes the hanging fixing pin 8 to move to the right, thus creating a gap between the two hanging fixing pin holes 7. The hanging bracket cantilever 15 is then placed into the gap. Since the pin return spring 9 is a compression spring with a rebound force, the hanging locking lever 19 uses the rebound force of the pin return spring 9 to drive the hanging fixing pin 8 to reset and re-insert into the rectangular hole of the hanging fixing pin hole 7. Its function is to enable the hanging bracket cantilever 15 to achieve automatic release and locking function, while the elasticity of the pin return spring 9 makes the locking more stable.
