[0002] Aluminum alloy plates are industrial building materials and are used in various industries according to different materials. They can be divided into two categories: non-painted products and painted products according to the surface treatment method. The industries using them include aircraft structures, rivets, missile components, truck wheels, packaging and heat-insulating aluminum foils, heat exchangers, frames, ribs, spars, etc.

[0003] During the processing of aluminum alloy plates, it is necessary to polish the aluminum alloy. However, most of the current polishing devices use hand-held angle grinders with polishing wheels to polish aluminum alloy plates. Such a method will first cause a certain working intensity for the staff, and it is inconvenient to polish the middle area of the aluminum alloy plate during the grinding and polishing process. Therefore, this technical solution proposes a polishing mechanism for aluminum alloy plates to solve the above-mentioned problems. Summary of the Utility Model

[0004] The purpose of the utility model is to solve the disadvantages in the prior art that using an angle grinder for grinding and polishing will first cause a certain working intensity for the staff, and it is inconvenient to polish the middle area of the aluminum alloy plate during the grinding and polishing process, and to propose a polishing mechanism for aluminum alloy plates.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0006] A polishing mechanism for aluminum alloy plates includes a bottom box. An outlet hole is opened on the inner wall of the bottom of one side of the bottom box. A waste box is slidably connected in the bottom box, and one side of the waste box extends to the outside of the bottom box. A table board is fixedly installed on the top of the bottom box. A through hole communicating with the bottom box is opened on the table board. Two adjusting holes are symmetrically opened on the table board. The polishing mechanism further includes:

[0007] A pressing mechanism is installed on the top of the table board and is used to limit the height of the aluminum alloy plate.

[0008] A polishing mechanism is installed in the bottom box. The top of the polishing mechanism penetrates through the through hole and extends above the table board, and both sides of the polishing mechanism extend to both sides of the bottom box respectively.

[0009] A limiting mechanism is installed at the bottom of the table board, and the tops of the limiting mechanism respectively penetrate through the two adjusting holes and extend above the table board.

[0010] In a possible design, the pressing mechanism includes a mounting frame fixedly installed on the top of the table board. An adjusting nut is fixedly installed on the top of the mounting frame. An adjusting screw rod is threadedly connected through the adjusting nut. The bottom end of the adjusting screw rod extends into the mounting frame and is rotatably connected to a moving frame. The moving frame is slidably connected to the inner walls on both sides of the mounting frame. A pressing roller is rotatably connected in the moving frame.

[0011] In a possible design, the polishing mechanism includes a support shaft rotatably connected in the bottom box. A polishing roller is fixedly sleeved on the support shaft. The top of the polishing roller penetrates through the perforation and extends into the mounting frame. One end of the support shaft extends to the outside of the bottom box. A power assembly is installed on one side of the bottom box. The power assembly penetrates through the bottom box and is connected to the support shaft.

[0012] In a possible design, the power assembly includes a driving motor fixedly installed on one side of the bottom box. The output shaft of the driving motor penetrates through the bottom box. Second synchronous pulleys are fixedly sleeved on both the bottom box and the support shaft on the outside of the bottom box. And the same second synchronous belt is sleeved on the two second synchronous pulleys.

[0013] In a possible design, the limiting mechanism includes two bidirectional screw rods. The two bidirectional screw rods are symmetrically rotatably connected to the bottom of the table board. Two limiting plates are symmetrically threadedly sleeved on the bidirectional screw rods. The tops of the two limiting plates penetrate through the corresponding adjusting holes and extend above the table board. The two limiting plates are both slidably connected to the inner walls of the adjusting holes. One end of the two bidirectional screw rods is connected to the same transmission assembly.

[0014] In a possible design, the transmission assembly includes two first synchronous pulleys respectively fixedly connected to one end of the two bidirectional screw rods. And the same first synchronous belt is sleeved on the two first synchronous pulleys.

[0015] In this application, first, rotate the bidirectional screw on one side according to the width of the aluminum alloy plate to be polished. Driven by the cooperation of two first synchronous pulleys and a first synchronous belt, the other bidirectional screw can be driven to rotate synchronously. When the bidirectional screw rotates, under the driving action of the threads with opposite thread directions at both ends, the two limit plates move towards each other, so as to adjust the distance between the two limit plates. When the aluminum alloy plate passes through the two limit plates, the two limit plates can be used to limit the aluminum alloy plate. After the aluminum alloy plate passes through the two limit plates on one side and is inserted into the mounting frame, at this time, rotate the adjusting screw. Under the thread driving action with the adjusting nut, the moving frame can be driven to move downward, so that the pressing roller can be used to press and limit the aluminum alloy plate, making the aluminum alloy plate in close contact with the polishing roller. Then, start the driving motor. Driven by the cooperation of two second synchronous pulleys and a second synchronous belt, the support shaft can be driven to rotate, so that the polishing roller can rotate stably to polish the aluminum alloy plate. After that, just manually push the aluminum alloy plate to adjust its position, so as to realize the comprehensive polishing of the aluminum alloy plate.

[0018] In the present utility model, for the aluminum alloy plate polishing mechanism, through the polishing mechanism, when starting the power component to drive the support shaft to rotate, at this time, the polishing roller can be driven to rotate, so as to polish the aluminum alloy plate.

[0019] In the present utility model, for the aluminum alloy plate polishing mechanism, through the limiting mechanism, when rotating one of the bidirectional screws, driven by the transmission component, the other bidirectional screw will also rotate. When the bidirectional screw rotates, under the driving action of the threads with opposite thread directions at both ends, the two limit plates move towards each other, so as to adjust the distance between the two limit plates. When the aluminum alloy plate passes through the two limit plates, the two limit plates can be used to limit the aluminum alloy plate.

[0020] The present utility model can realize the automatic polishing of the aluminum alloy plate. Compared with the method of using a hand-held angle grinder, it can greatly reduce the labor intensity of the staff and can also realize the comprehensive polishing of the aluminum alloy plate, so it has good usability.
