Technical Field

[0001] This utility model relates to the technical field of alloy coating devices, specifically a coating device for aluminum alloy surfaces. Background Technology

[0002] A coating apparatus for aluminum alloy surfaces typically includes key components such as a coating tank, a drive mechanism, and a clamping mechanism. This apparatus can automatically coat aluminum alloy surfaces, ensuring uniform coating without altering the inner diameter or shape of the aluminum alloy. Specific designs may vary depending on the manufacturer and application requirements, but the core function is to improve coating efficiency and coating quality.

[0003] For example, a surface coating device for aluminum alloy products, disclosed in publication number CN112981295B, specifically includes a base plate, a coating tank fixedly connected to the upper end of the base plate, a push plate slidably connected inside the coating tank, a drive mechanism for driving the push plate on the coating tank, two vertical plates fixedly connected to the upper end of the base plate, a horizontal plate between the two vertical plates, an adjustment mechanism for adjusting the horizontal plate on the two vertical plates, a lifting plate below the horizontal plate, a lifting mechanism for raising and lowering the lifting plate on the horizontal plate, two sliding plates slidably connected below the lifting plate, a moving mechanism for moving the two sliding plates on the horizontal plate, and a clamping mechanism for clamping aluminum alloy tubes between the two sliding plates.

[0004] Existing coating equipment for aluminum alloy surfaces cannot process workpieces of different sizes during use. The inability to process workpieces of different sizes means that frequent equipment changes or process adjustments are required, which reduces production efficiency. Therefore, we propose a coating equipment for aluminum alloy surfaces. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a coating device for aluminum alloy surfaces.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0007] This utility model discloses a coating device for aluminum alloy surfaces, including a coating chamber. The coating chamber is provided with two sets of mirror-distributed fixing mechanisms, which are installed on the inner side of the coating chamber and are used to fix the aluminum alloy workpiece in the coating chamber.

[0008] The fixing mechanism includes a bracket disposed within a coating chamber. A connecting shaft is fixedly installed on one side of the bracket and rotatably mounted inside the coating chamber. A frame is provided on one side of the bracket, and an adjustment component is provided on the bracket. The adjustment component is connected to the frame and used to adjust the position of the frame. Two spaced movable rods pass through the upper and lower sides of the frame. Anti-slip plates are fixedly installed at the ends of the movable rods, and circular plates are fixedly installed at the other ends of the movable rods. A first spring is sleeved on each movable rod, and the two ends of the first spring are fixedly connected to the frame and the circular plate, respectively. A rotating mechanism is provided outside the coating chamber and is connected to the connecting shaft on one side. The rotating mechanism is used to adjust the angle of the aluminum alloy workpiece inside the coating chamber.

[0009] As a preferred embodiment of this utility model, the adjustment assembly includes two guide rods, one end of which is fixedly connected to the frame and the other end of which passes through the bracket. A rack is fixedly installed on the frame, one end of which extends into the bracket.

[0010] As a preferred technical solution of this utility model, the adjustment component further includes a disc, which is fixedly connected to the end of the first rotating shaft. The disc has a plurality of through holes arranged in a circumferential array. The disc is provided with a rod, which passes through the through holes and is threaded to the bracket at the other end.

[0011] As a preferred embodiment of this utility model, the rotating mechanism includes a protective cover, which is fixedly connected to the outside of the coating chamber. A second rotating shaft is provided inside the protective cover. The second rotating shaft is rotatably mounted on the coating chamber and fixedly connected to a connecting shaft. A driven wheel is fixedly mounted at one end of the second rotating shaft. A motor is fixedly mounted on the coating chamber inside the protective cover.

[0014] The beneficial effects of this utility model are:

[0015] 1. This coating device for aluminum alloy surfaces involves removing a probe through a through-hole. A rotating disc drives a first rotating shaft and gears to rotate, causing the frames on both sides to move closer or further apart. The distance between the frames can be adjusted according to the size of the workpiece. The device can hold workpieces of different sizes for coating processing. It can handle workpieces of different sizes without frequent equipment changes or process parameter adjustments, thus improving production flexibility and adaptability.

[0016] 2. This coating device for aluminum alloy surfaces uses a motor to drive an incomplete gear, causing the connecting shaft, support, and frame to rotate synchronously. This causes the workpiece between the two side frames to rotate intermittently around the connecting shaft, allowing the workpiece to adjust its coating position. When the incomplete gear separates from the driven gear, the electromagnet is energized and applies a repulsive force to the magnetic plate, causing one end of the limiting rod to insert into the limiting hole. The workpiece remains stable and undergoes coating processing. The workpiece can rotate during processing, allowing for uniform coating from all directions. Attached Figure Description

[0024] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0025] Example: Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, this utility model discloses a coating device for aluminum alloy surfaces, including a coating chamber 1. Two sets of mirror-distributed fixing mechanisms are installed inside the coating chamber 1, and these fixing mechanisms are used to fix the aluminum alloy workpieces inside the coating chamber 1. Each fixing mechanism includes a bracket 2, which is located inside the coating chamber 1. A connecting shaft 3 is fixedly installed on one side of the bracket 2, and the connecting shaft 3 is rotatably installed inside the coating chamber 1. A frame 4 is provided on one side of the bracket 2, and an adjustment component is provided on the bracket 2. The adjustment component is connected to the frame 4 and used to adjust the position of the frame 4. Two spaced movable rods 5 pass through the upper and lower sides of the frame 4. Anti-slip plates 6 are fixedly installed at the ends of the movable rods 5, and circular plates 7 are fixedly installed at the other ends of the movable rods 5. A first spring 8 is sleeved on each movable rod 5, and the two ends of the first spring 8 are fixedly connected to the frame 4 and the circular plates 7, respectively. A rotating mechanism is provided outside the coating chamber 1, and the rotating mechanism is connected to the connecting shaft 3 on one side. The rotating mechanism is used to adjust the angle of the aluminum alloy workpieces inside the coating chamber 1.

[0026] The adjustment assembly includes two guide rods 9, one end of which is fixed to the frame 4 and the other end of which passes through the bracket 2. A rack 10 is fixedly installed on the frame 4, with one end of the rack 10 extending into the bracket 2. A first rotating shaft 11 is rotatably installed inside the bracket 2, and a gear 12 is fixedly installed on the first rotating shaft 11, meshing with the rack 10. The adjustment assembly also includes a disc 13, which is fixedly connected to the end of the first rotating shaft 11. The disc 13 has multiple perforations 14 arranged in a circumferential array, and a rod 15 is provided on the disc 13. The rod 15 passes through the perforations 14 and its other end is threaded to the bracket 2. By placing the workpiece in the coating chamber 1, with both ends of the workpiece located in the frames 4 on both sides, and the workpiece being in a stretched state by the first spring 8, and the anti-slip plate 6 pressing on the workpiece and applying compressive force, the workpiece can be fixed in the coating chamber 1. When the size of the workpiece changes, the insert rod 15 is removed from the through hole 14, allowing the rotating disc 13 to drive the first rotating shaft 11 and gear 12 to rotate. The gear 12 drives the rack 10 to move, and the rack 10 and frame 4 rotate synchronously, thereby causing the frames 4 on both sides to move closer or further apart. The distance between the frames 4 on both sides can be adjusted according to the size of the workpiece. The insert rod 15 then passes through the through hole 14 and is threaded to the bracket 2 at the other end, which can fix the gear 12 and thus fix the position of the frame 4.

[0027] The rotating mechanism includes a protective cover 16, which is fixedly connected to the outside of the coating chamber 1. A second rotating shaft 17 is provided inside the protective cover 16. The second rotating shaft 17 is rotatably mounted on the coating chamber 1 and fixedly connected to the connecting shaft 3. A driven wheel 18 is fixedly mounted on one end of the second rotating shaft 17. A motor 19 is fixedly mounted on the coating chamber 1 inside the protective cover 16. An incomplete gear 20 is fixedly mounted on the output shaft end of the motor 19. The incomplete gear 20 meshes with the driven wheel 18. A circular block 21 is fixedly installed on the second rotating shaft 17. Multiple limiting holes 22 arranged in a circumferential array are provided on the circular block 21. Multiple support plates 23 arranged in a circumferential array are provided on the outer side of the circular block 21. The support plates 23 are fixedly connected to the coating chamber 1. A limiting rod 24 passes through the support plate 23. One end of the limiting rod 24 is inserted into the limiting hole 22, and the other end of the limiting rod 24 is fixedly connected to a magnetic plate 25. A second spring 26 is sleeved on the limiting rod 24, and both ends of the second spring 26 are fixedly connected to the magnetic plate 25 and the support plate 23, respectively. An arc-shaped plate 27 is fixedly installed inside the protective cover 16 on the coating chamber 1. Multiple electromagnets 28 arranged in a circumferential array are fixedly installed on the inner side of the arc-shaped plate 27, and the electromagnets 28 are respectively positioned facing the magnetic plate 25. During processing, the motor 19 drives the incomplete gear 20 to rotate, which intermittently drives the driven wheel 18 to rotate. The second rotating shaft 17 rotates intermittently, and the connecting shaft 3, bracket 2, and frame 4 rotate synchronously, thereby causing the workpiece between the two frames 4 to rotate intermittently around the connecting shaft 3. The workpiece's coating position can be adjusted. When the incomplete gear 20 separates from the driven wheel 18, the electromagnet 28 is energized and applies a repulsive force to the magnetic sheet 25, causing one end of the limiting rod 24 to insert into the limiting hole 22. The second spring 26 is compressed, which can fix the angle of the circular block 21. At the same time, the angle between the second rotating shaft 17 and the workpiece is fixed. At this time, the workpiece remains stable and undergoes coating processing. After this processing is completed, the angle of the workpiece is adjusted again.

[0028] Working principle: Please refer to the schematic diagram of the device. Figure 2 As shown, by placing the workpiece in the coating chamber 1, with both ends of the workpiece located within the frames 4 on both sides, and the first spring 8 in a stretched state, the anti-slip plate 6 presses against the workpiece and applies compressive force, the workpiece can be fixed in the coating chamber 1. When the size of the workpiece changes, the insert rod 15 is removed from the through hole 14, and the rotating disk 13 drives the first rotating shaft 11 and gear 12 to rotate. The gear 12 drives the rack 10 to move, and the rack 10 and frame 4 rotate synchronously, thereby causing the frames 4 on both sides to move closer or further apart. The distance between the frames 4 on both sides can be adjusted according to the size of the workpiece. The insert rod 15 passes through the through hole 14, and the other end is threaded to the bracket 2, which can fix the gear 12, thereby fixing the position of the frame 4. The device can hold workpieces of different sizes and perform coating processing. This device can handle workpieces of different sizes without frequent equipment changes or process parameter adjustments, thereby improving production flexibility and adaptability.

[0029] During processing, the motor 19 drives the incomplete gear 20 to rotate, which intermittently drives the driven wheel 18 to rotate. The second rotating shaft 17 rotates intermittently, and the connecting shaft 3, bracket 2, and frame 4 rotate synchronously, thereby causing the workpiece between the two frames 4 to rotate intermittently around the connecting shaft 3. The workpiece's coating position can be adjusted. When the incomplete gear 20 separates from the driven wheel 18, the electromagnet 28 is energized and applies a repulsive force to the magnetic sheet 25, causing one end of the limiting rod 24 to insert into the limiting hole 22. The second spring 26 is compressed, which can fix the angle of the round block 21. At the same time, the angle between the second rotating shaft 17 and the workpiece is fixed. At this time, the workpiece remains stable and undergoes coating processing. After this processing is completed, the angle of the workpiece is adjusted again. The electromagnet 28 is de-energized, and the elastic force of the second spring 26 drives the limiting rod 24 to disengage from the limiting hole 22. At this time, the incomplete gear 20 meshes with the driven wheel 18 again and adjusts the angle of the workpiece. The subsequent work cycle repeats until the coating is completed at different positions on the workpiece surface. The workpiece can be rotated during processing, and a uniform coating can be applied to the workpiece from all directions during the coating process.

[0030] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
