Abstract
Description
Technical Field
[0001] This utility model relates to the field of aluminum alloy processing technology, and more specifically, to an aluminum alloy chemical polishing device. Background Technology
[0002] Aluminum alloys are alloys with aluminum as the base and a certain amount of other alloying elements added. They are one of the light metal materials. In addition to the general properties of aluminum, aluminum alloys also have some specific alloy properties due to the different types and amounts of alloying elements added. They have high strength, with a specific strength close to that of high alloy steel and a specific stiffness exceeding that of steel. They also have good casting and plastic processing properties, good electrical and thermal conductivity, good corrosion resistance and weldability, and can be used as structural materials. They are widely used in aerospace, aviation, transportation, construction, electromechanical, light chemical and daily necessities. After the aluminum alloy sheet is processed, its surface needs to be polished, which not only improves the use effect of the aluminum alloy sheet, but also increases its aesthetics.
[0003] Existing aluminum alloy polishing methods often employ chemical polishing. The working principle of chemical polishing of aluminum alloys involves utilizing the selective self-dissolution of aluminum and aluminum alloys in acidic or alkaline electrolyte solutions to smooth and polish the workpiece surface, thereby reducing its surface roughness. However, some existing aluminum alloy polishing devices stack aluminum alloy sheets within a frame containing a chemical solution, relying on the chemical solution to dissolve and polish the aluminum alloy. This can lead to insufficient contact between parts of the aluminum alloy and the solution, thus reducing the polishing effect. Therefore, we propose an aluminum alloy chemical polishing device. Utility Model Content
[0004] To solve the above problems, this utility model provides an aluminum alloy chemical polishing device, which adopts the following technical solution:
[0005] An aluminum alloy chemical polishing device includes a frame, a controller on one side of the frame, columns at the four corners of the bottom of the frame, a placement frame inside the frame, multiple partitions arranged in a linear array inside the placement frame, support frames fixedly installed on both sides of the frame, a lifting plate on the top of the frame, the lifting plate having an inverted "U" shaped cross-section, the two ends of the lifting plate slidingly placed in the support frame on the same side, cylinders on the inner walls of the bottom of the two support frames, the piston shaft ends of the two cylinders fixedly connected to the opposite side of the lifting plate, a swing assembly between the placement frame and the lifting plate, and a wind blowing assembly on the top of the lifting plate.
[0006] The bottom inner wall of the frame has two symmetrically distributed protective frames, each containing a heating tube. A temperature sensor is located on one side of the inner wall of the frame, and a stirring assembly is located inside the frame.
[0007] By adopting the above technical solution, the equipment operates by using two cylinders to drive a lifting plate upwards. The lifting plate, along with the placement frame, rises synchronously, moving the placement frame above the frame body. The placement frame is divided into multiple placement areas by partitions, facilitating the placement of materials by workers and reducing contact points between materials, ensuring uniform contact between the materials and the solution. After the materials are placed, the cylinders drive the placement frame to move into the frame body. The frame body is equipped with heating pipes that generate heat to heat the solution, improving polishing efficiency. Furthermore, the frame body contains a stirring component to agitate the solution, further enhancing uniform contact between the solution and heat, and allowing the solution to impact the materials. This design improves the polishing efficiency of the board and includes a temperature sensor inside the frame to detect the solution temperature, preventing damage to the board from overheating. A swing assembly at the top of the frame drives the frame to move back and forth within the frame, ensuring even contact between the solution and the board. After polishing, a cylinder drives the frame to rise again, and a wind-blowing assembly generates airflow on the board surface, accelerating the dripping of any remaining solution and facilitating subsequent handling. The frame, partitions, and protective frame all have rectangular arrays of through-holes to allow the solution to pass through and contact the board.
[0008] Furthermore, the swing assembly includes two connecting plates fixedly installed at the top of the placement frame. The two connecting plates are symmetrically distributed at the top of the placement frame. A frame is provided below the lifting plate. Movable slots are provided on both sides of the connecting plates. Stabilizing blocks are slidably installed in both movable slots. The opposite ends of the two stabilizing blocks are fixedly connected to the opposite side of the frame. Toothed plates are fixedly installed on the inner walls of both sides of the frame. A first reduction motor is fixedly installed on the inner wall of the top of the lifting plate. An incomplete gear is fixedly sleeved on the output shaft of the first reduction motor. The incomplete gear meshes with the toothed plate.
[0009] By adopting the above technical solution, the incomplete gear is driven to rotate by the first reduction motor. The incomplete gear meshes with one of the toothed plates, thereby driving the frame to move the placement frame inside the frame. When the incomplete gear disengages from one of the toothed plates, it meshes with the other toothed plate, thereby causing the frame to move the placement frame to the other side. Through the cooperation of the incomplete gear and the two toothed plates, the placement frame moves back and forth inside the frame, which facilitates uniform contact between the plate and the solution and helps to improve the polishing efficiency of the plate.
[0010] Furthermore, each of the two stabilizing blocks has a plug fixedly installed at one end opposite to it, and slots matching the plugs on the same side are provided on both sides of the frame.
[0011] By adopting the above technical solution, when installing the stabilizing block, the worker passes the stabilizing block through the moving slot opened on the side wall of the lifting plate and contacts the side opposite to the frame. There is an insert on one side of the stabilizing block, which engages with the slot opened on the opposite side of the frame to position the stabilizing block, making it easier to assemble the stabilizing block and the frame with fasteners of existing technology.
[0012] Furthermore, the air blowing assembly includes a mounting box fixedly installed on the top of the lifting plate, a second geared motor fixedly installed inside the mounting box, fan blades fixedly sleeved on the side wall of the output shaft of the second geared motor, and multiple through holes distributed in a linear array on the top of the lifting plate.
[0013] By adopting the above technical solution, after the board is polished, the placement frame is driven by the cylinder to lift the board, and then the fan blades are driven by the second reduction motor to generate wind. The wind acts on the placement frame and the surface of the board, which helps to increase the dripping speed of residual solution on the surface of the board, thereby cleaning the board and facilitating subsequent transportation and cleaning by the staff.
[0014] Furthermore, the stirring assembly includes a rotating rod rotatably mounted on the inner wall of the bottom end of the frame. A collar is fitted on the upper side wall of the rotating rod, and the collar and the rotating rod are fixed together by bolts. Multiple stirring plates arranged in a ring array are fixedly installed on the side wall of the collar. A protective box is fixedly installed at the bottom end of the frame, and a third geared motor is fixedly installed inside the protective box. The bottom end of the rotating rod passes through the frame and extends into the protective box. One end of the rotating rod passing through the protective box is fixedly connected to the end of the output shaft of the third geared motor.
[0015] By adopting the above technical solution, when the solution is heated by the heat generated by the heating tube, the rotating rod is driven to rotate by the third reduction motor. The rotating rod drives the collar and the stirring plate to rotate synchronously, which plays the role of stirring the solution. This is beneficial to improving the mixing efficiency of the solution and heat. Moreover, the solution shakes and impacts the plate inside the frame, which facilitates uniform contact between the solution and the plate and is beneficial to improving the polishing efficiency of the plate.
[0016] Furthermore, two symmetrically distributed first positioning blocks are fixedly installed on the inner wall of the collar, and a first positioning groove matching the first positioning blocks is opened on the upper side wall of the rotating rod.
[0017] By adopting the above technical solution, the collar and the rotating rod are fixed together by bolts, which facilitates subsequent disassembly. When the collar is provided with a first positioning block, the first positioning block and the first positioning groove opened on the side wall of the rotating rod are engaged to fix the collar in place, which facilitates subsequent fixing.
[0018] Furthermore, two symmetrically distributed second positioning blocks are fixedly installed at the bottom of both protective frames, and a second positioning groove matching the second positioning block is opened on the inner wall of the bottom of the frame.
[0019] By adopting the above technical solution, a second positioning block is provided at the bottom of the protective frame. The second positioning block engages with the second positioning groove opened on the inner wall of the bottom of the frame, which plays the role of positioning and stabilizing the protective frame, and facilitates subsequent fastening with existing fasteners.
[0020] In summary, this utility model has the following beneficial technical effects:
[0021] (1) In this utility model, the placement frame is divided into multiple placement areas by partitions, which facilitates the placement of aluminum alloy plates separately, reduces the contact points between plates, and thus increases the contact area between the plates and the solution, thereby improving the polishing effect of the plates.
[0022] (2) In this utility model, the heating tube is controlled by the controller to generate heat, which plays the role of heating the solution, which is beneficial to improving the polishing efficiency of the equipment. The frame is equipped with a stirring component, which plays the role of stirring the solution, which is beneficial to improving the heating efficiency of the solution.
[0023] (3) In this utility model, the incomplete gear is driven to rotate by the first reduction motor. The incomplete gear meshes with one of the toothed blocks, thereby driving the frame to move with the placement frame inside the frame. When the incomplete gear disengages from one of the toothed blocks, the incomplete gear meshes with the other toothed block, thereby causing the frame to move with the placement frame to the other side. Through the cooperation of the incomplete gear and the two toothed blocks, the placement frame moves back and forth inside the frame, which facilitates uniform contact between the plate and the solution and helps to improve the polishing efficiency of the plate.

[0036] The following is in conjunction with the appendix Figure 1-7 The present invention will be described in further detail below.
[0037] Please see Figure 1-7An aluminum alloy chemical polishing device includes a frame 1, a controller on one side of the frame 1, columns at the four corners of the bottom of the frame 1, a placement frame 2 inside the frame 1, a plurality of partitions arranged in a linear array inside the placement frame 2, support frames 4 fixedly installed on both sides of the frame 1, and a lifting plate 5 above the frame 1. The lifting plate 5 has an inverted "U" shaped cross section, and the two sections of the lifting plate 5 are slidably placed in the support frames 4 on the same side. Cylinders 12 are provided on the inner walls of the bottom of the two support frames 4, and the piston shaft ends of the two cylinders 12 are fixedly connected to the side opposite to the lifting plate 5.
[0038] A swing assembly is provided between the placement frame 2 and the lifting plate 5. The swing assembly includes two connecting plates 3 fixedly installed at the top of the placement frame 2.

Movable slots 24 are provided on both sides of the connecting plates 3. Stabilizing blocks 6 are slidably installed in both movable slots 24. The opposite ends of the two stabilizing blocks 6 are fixedly connected to the opposite side of the frame 7. Toothed plates 11 are fixedly installed on the inner walls of both sides of the frame 7. A first reduction motor 9 is fixedly installed on the inner wall at the top of the lifting plate 5. An incomplete gear 10 is fixedly sleeved on the output shaft of the first reduction motor 9. The incomplete gear 10 meshes with the toothed plate 11.
[0039] When in use, the device is driven by two cylinders 12 to lift the lifting plate 5, which in turn lifts the placement frame 2, moving it above the frame 1. The placement frame 2 is divided into multiple placement areas by partitions, facilitating the placement of the boards by the staff, reducing the contact points between the boards, and ensuring uniform contact between the boards and the solution. After the boards are placed, the cylinders 12 drive the placement frame 2 to move into the frame 1. The first reduction motor 9 drives the incomplete gear 10 to rotate, which meshes with one of the toothed plates 11, thereby driving the frame 7 to move the placement frame 2 within the frame 1. When the incomplete gear 10 disengages from one of the toothed plates 11, it meshes with the other toothed plate 11, causing the frame 7 to move the placement frame 2 to the other side. Through the cooperation of the incomplete gear 10 and the two toothed plates 11, the placement frame 2 moves back and forth within the frame 1, ensuring uniform contact between the boards and the solution and improving the polishing efficiency of the boards.
[0040] Two stabilizing blocks 6 are fixedly installed with inserts 23 at opposite ends. The frame 7 has slots on both sides that match the inserts 23 on the same side. When installing the stabilizing blocks 6, the workers pass the stabilizing blocks 6 through the moving slots 24 opened on the side wall of the lifting plate 5 and make contact with the side opposite to the frame 7. The stabilizing blocks 6 have inserts 23 on one side. The inserts 23 engage with the slots opened on the side opposite to the frame 7, which serves to position the stabilizing blocks 6 and facilitate the subsequent assembly of the stabilizing blocks 6 and the frame 7 using fasteners of existing technology.
[0041] The inner wall of the bottom end of the frame 1 is provided with two symmetrically distributed protective frames 16. Each of the two protective frames 16 is provided with a heating tube 17. A temperature sensor is provided on one side of the inner wall of the frame 1. The frame 1 is provided with a stirring assembly, which includes a rotating rod 20 rotatably mounted on the inner wall of the bottom end of the frame 1. A collar 21 is sleeved on the upper side wall of the rotating rod 20. The collar 21 and the rotating rod 20 are fixed together by bolts. Multiple stirring plates 15 arranged in a ring array are fixedly installed on the side wall of the collar 21. A protective box 18 is fixedly installed at the bottom end of the frame 1. A third reduction motor 19 is fixedly installed inside the protective box 18. The bottom end of the rotating rod 20 passes through the frame 1 and extends into the protective box 18. One end of the rotating rod 20 passing through the protective box 18 is fixedly connected to the end of the output shaft of the third reduction motor 19.
[0042] A heating tube 17 is installed inside the frame 1. Heat is generated by the heating tube 17 to heat the solution, which helps to improve the polishing efficiency of the board. When the solution is heated by the heat generated by the heating tube 17, the rotating rod 20 is driven to rotate by the third reduction motor 19. The rotating rod 20 drives the collar 21 and the stirring plate 15 to rotate synchronously, which plays the role of stirring the solution. This helps to improve the mixing efficiency of the solution and heat. Moreover, the solution shakes and impacts the board inside the frame 1, which facilitates uniform contact between the solution and the board, which helps to improve the polishing efficiency of the board.
[0043] Two symmetrically distributed first positioning blocks 22 are fixedly installed on the inner wall of the collar 21. The upper side wall of the rotating rod 20 is provided with a first positioning groove that matches the first positioning blocks 22. The collar 21 and the rotating rod 20 are fixed together by bolts, which facilitates subsequent disassembly. When the first positioning block 22 is provided on the inner side of the collar 21, the first positioning block 22 and the first positioning groove on the side wall of the rotating rod 20 are engaged to fix the collar 21 in a stable position, which facilitates subsequent fixation.
[0044] The top of the lifting plate 5 is equipped with a wind blowing assembly, which includes a mounting box 8 fixedly installed on the top of the lifting plate 5. A second reduction motor 13 is fixedly installed inside the mounting box 8. A fan blade 14 is fixedly sleeved on the side wall of the output shaft of the second reduction motor 13. The top of the lifting plate 5 has multiple through holes arranged in a linear array. After the plate is polished, the cylinder 12 drives the placement frame 2 to lift the plate. Then, the second reduction motor 13 drives the fan blade 14 to rotate and generate wind. The wind acts on the placement frame 2 and the surface of the plate, which helps to increase the dripping speed of residual solution on the surface of the plate, thereby cleaning the plate and facilitating subsequent transportation and cleaning by the staff.
[0045] Two symmetrically distributed second positioning blocks 25 are fixedly installed at the bottom of each of the two protective frames 16. The inner wall of the bottom of the frame 1 is provided with a second positioning groove that matches the second positioning block 25. The bottom of the protective frame 16 is provided with a second positioning block 25. The second positioning block 25 and the second positioning groove opened at the bottom of the frame 1 engage to fix the protective frame 16 in a stable position, which is convenient for subsequent fastening with existing technology.
[0046] The implementation principle of this utility model embodiment is as follows: When the device is in use, two cylinders 12 drive the lifting plate 5 to rise, and the lifting plate 5 carries the placement frame 2 to rise synchronously, so that the placement frame 2 moves above the frame body 1. The placement frame 2 is divided into multiple placement areas by partitions, which facilitates the placement of the board by the staff, helps to reduce the contact points between the boards, and facilitates uniform contact between the board and the solution. After the board is placed, the cylinders 12 drive the placement frame 2 to move into the frame body 1. The frame body 1 is equipped with a heating tube 17, which generates heat to heat the solution, which helps to improve the polishing efficiency of the board. The frame body 1 is also equipped with a stirring component, which plays a role in stirring the solution, which helps to improve the uniform contact between the solution and the heat, and can make the solution... The liquid impact on the plate improves the polishing efficiency. A temperature sensor inside the frame 1 detects the solution temperature, preventing damage to the plate from overheating. A swing assembly at the top of the placement frame 2 drives it to move back and forth within the frame 1, ensuring even contact between the solution and the plate. After polishing, cylinder 12 drives the placement frame 2 upwards, while a wind-blowing assembly generates airflow that accelerates the dripping of residual solution, facilitating subsequent plate removal. The placement frame 2, partition, and protective frame 16 all have rectangular arrayed through-holes to allow solution to pass through and contact the plate.
[0047] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
