Description

Technical Field

[0001] The utility model relates to the technical field of aluminum alloy processing equipment, in particular to a polishing and grinding device for aluminum alloy. Background Technique

[0002] Aluminum alloy is an alloy based on aluminum with a certain amount of other alloying elements added, and it is one of the light metal materials. Aluminum alloy is one of the most widely used non-ferrous metal structural materials in industry and has been widely used in aviation, aerospace, automotive, machinery manufacturing, shipbuilding, and chemical industries. During the production and processing of aluminum alloy, it usually needs to be polished, so a special polishing and grinding device is required.

[0003] In the Chinese utility model patent with the publication number of CN218874999U, a surface polishing machine is disclosed. The device inputs water into the sprayer through a water tank, and then the water is sprayed out by the sprayer. While spraying, it can cool the aluminum alloy being polished, and at the same time, it also avoids scratches caused by waste chips on the surface of aluminum alloy die-casting being polished by the polishing disc, resulting in more serious damage, thereby improving the processing quality of aluminum alloy. For the above related technologies, the inventor believes there are the following defects:

[0004] During the actual use of this device, since the protective oxide film on the surface of the aluminum alloy will be weakened during the grinding process, coupled with the attachment of water and the lack of an integrated structure that can automatically remove the moisture on the surface of the aluminum alloy, the rusting of the grinding surface of the aluminum alloy will be accelerated under the combined action of water and air, thereby reducing the processing quality of the aluminum alloy. Therefore, we provide a polishing and grinding device for aluminum alloy. Content of the Utility Model

[0005] To solve the problem in the above background technique that it is difficult to automatically remove the moisture on the grinding surface, which leads to the acceleration of the rusting of the grinding surface of the aluminum alloy, the utility model provides a polishing and grinding device for aluminum alloy.

[0006] The utility model is realized by adopting the following technical solutions: A polishing and grinding device for aluminum alloy, comprising:

[0007] A base, the top of the base is movably connected with a grinding table, the top of the base is symmetrically and fixedly connected with electric push rods, and the telescopic ends of the electric push rods are fixedly connected with the grinding table. The top of the base is fixedly connected with a bracket, the top of the bracket is fixedly connected with a water tank, the inner side of the bracket is provided with a nozzle and is communicated with the water tank, one side of the bracket is rotatably connected with a grinding roller, and one side of the grinding roller is coaxially and fixedly connected with a motor;

[0008] Wiping assembly, the wiping assembly includes two groups of slide bars symmetrically and fixedly connected to the top of the base. A same slide plate is slidably connected to the outside of the two groups of slide bars. A first toothed plate is fixedly connected to the top of the slide plate. A connecting frame is fixedly connected to the top of the base. A second toothed plate is movably connected to the bottom of the connecting frame. One end of the second toothed plate is fixedly connected to a sponge block through a connecting seat. A rotating shaft is rotatably connected to the connecting frame. A gear is fixedly sleeved on the outer side of the middle of the rotating shaft and is meshed with the first toothed plate and the second toothed plate at the same time. A spring is sleeved on the outside of the slide bar.

[0009] As a further improvement of the above solution, one side of the connecting seat is fixedly connected to a fixing plate and is in contact with the sponge block. An extrusion plate is fixedly connected to the connecting frame through a connecting rod and is on the same horizontal line as the fixing plate.

[0010] As a further improvement of the above solution, a strip-shaped groove is opened at the top of the grinding table. A bidirectional lead screw is rotatably connected to the inside of the strip-shaped groove. Moving blocks are threadedly connected to the outer sides of both sides of the bidirectional lead screw. A clamping plate is fixedly connected to the top of the moving block.

[0011] As a further improvement of the above solution, limiting grooves are symmetrically opened at the top of the grinding table. Limiting blocks are symmetrically and fixedly connected to the bottom of the clamping plate and are slidably connected to the limiting grooves.

[0012] As a further improvement of the above solution, a submersible pump is fixedly connected to the inside of the water tank. The water outlet end of the submersible pump is communicated with the spray head through a connecting pipe.

[0013] As a further improvement of the above solution, rollers are rotatably connected to the four corners of the bottom of the grinding table.

[0014] As a further improvement of the above solution, a limiting chute is opened at the bottom of the connecting frame. A limiting slide bar is fixedly connected to the top of the second toothed plate and is slidably connected to the limiting chute.

[0015] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0016] 1. In the present utility model, the grinding table is pushed to move by the electric push rod. The grinding table will then push the slide plate to slide on the slide bar and compress the spring. The movement of the slide plate drives the first toothed plate to move together. Under the meshing action of the first toothed plate and the gear, the gear can be driven to rotate. By using the meshing action of the gear and the second toothed plate, the second toothed plate can be driven to move, so that the sponge block can be driven to move. Since the moving directions of the grinding table and the sponge block are moving towards each other, the sponge block can automatically wipe and remove the water on the surface of the aluminum alloy, effectively avoiding the problem that the corrosion of the grinding surface of the aluminum alloy is accelerated due to the difficulty of automatically removing the water on the grinding surface.

[0017] 2. When the grinding table is far away from the slide plate in the present utility model, by using the resilience of the spring, the first tooth plate and the second tooth plate can be driven to reset. At this time, the sponge block will continuously approach and contact the extrusion plate. Through the combined action of the fixing plate and the extrusion plate, the water absorbed by the sponge block can be automatically squeezed out during the reset process of the sponge block, so as to ensure that the sponge block can always maintain good water absorption capacity and has strong practicability.

[0026] Base 1, a polishing table 2 is movably connected to the top of the base 1, electric push rods 3 are symmetrically and fixedly connected to the top of the base 1, and the telescopic ends of the electric push rods 3 are fixedly connected to the polishing table 2. A support is fixedly connected to the top of the base 1, a water tank 4 is fixedly connected to the top of the support, a spray head is arranged on the inner side surface of the support and is communicated with the water tank 4. One side of the support is rotatably connected to a polishing roller 5, and a motor is coaxially and fixedly connected to one side of the polishing roller 5. A strip-shaped groove is opened on the top of the polishing table 2, a bidirectional lead screw 8 is rotatably connected inside the strip-shaped groove, moving blocks are threadedly connected to both outer sides of the bidirectional lead screw 8, and clamping plates 9 are fixedly connected to the tops of the moving blocks, which is convenient for clamping and fixing the aluminum alloy to ensure stability during polishing. Limit grooves are symmetrically opened on the top of the polishing table 2, and limit blocks are symmetrically and fixedly connected to the bottoms of the clamping plates 9 and are slidably connected to the limit grooves, which can play a guiding role in the stable movement of the clamping plates 9. A submersible pump is fixedly connected inside the water tank 4, and the water outlet end of the submersible pump is communicated with the spray head through a connecting pipe. The submersible pump can convey water into the spray head and spray it out to wash the debris on the surface of the aluminum alloy and cool the aluminum alloy. Rollers are rotatably connected to the four corners of the bottom of the polishing table 2, which is convenient for the movement of the polishing table 2;

[0027] A wiping assembly, the wiping assembly includes two groups of slide bars 101 symmetrically and fixedly connected to the top of the base 1. The same slide plate 102 is slidably connected to the outer sides of the two groups of slide bars 101. A first toothed plate 103 is fixedly connected to the top of the slide plate 102. A connecting frame 104 is fixedly connected to the top of the base 1. A second toothed plate 105 is movably connected to the bottom of the connecting frame 104. One end of the second toothed plate 105 is fixedly connected to a sponge block 106 through a connecting seat. A rotating shaft 107 is rotatably connected to the connecting frame 104. A gear 108 is fixedly sleeved on the outer side of the middle part of the rotating shaft 107 and is meshed with both the first toothed plate 103 and the second toothed plate 105 at the same time. A spring 109 is sleeved on the outer side of the slide bar 101. A limit chute is opened at the bottom of the connecting frame 104. A limit slide bar is fixedly connected to the top of the second toothed plate 105 and is slidably connected to the limit chute, which can play a guiding role in the horizontal movement of the second toothed plate 105.

[0028] In the embodiment of the present application, the implementation principle of a polishing and grinding device for aluminum alloy is as follows: First, place the aluminum alloy on the grinding table 2, then rotate the bidirectional lead screw 8. The rotation of the bidirectional lead screw 8 drives the two groups of moving blocks to move towards each other, so as to drive the two groups of clamping plates 9 to move towards each other to clamp the aluminum alloy. Then start the motor, and the motor can drive the grinding roller 5 to rotate. After that, start the electric push rod 3, and the electric push rod 3 can push the grinding table 2 to move, so as to push the aluminum alloy to move. The aluminum alloy will be ground after passing through the grinding roller 5. The submersible pump can transport the water in the water tank 4 into the nozzle and spray it out to wash the debris on the surface of the aluminum alloy and cool the aluminum alloy. As the grinding table 2 continues to move, the grinding table 2 will push the slide plate 102 to slide on the slide rod 101 and compress the spring 109. The movement of the slide plate 102 drives the first toothed plate 103 to move together. Under the meshing action of the first toothed plate 103 and the gear 108, the gear 108 can be driven to rotate. Using the meshing action of the gear 108 and the second toothed plate 105, the second toothed plate 105 can be driven to move, so as to drive the sponge block 106 to move. Since the moving directions of the grinding table 2 and the sponge block 106 are towards each other, the sponge block 106 can automatically wipe and remove the water on the surface of the aluminum alloy. Finally, release the aluminum alloy and take away the aluminum alloy.

[0030] On the basis of Embodiment 1, the further improvement of this embodiment is that one side of the connecting seat is fixedly connected with a fixing plate 6 and is in contact with the sponge block 106. On the connecting frame 104, a pressing plate 7 is fixedly connected through a connecting rod and is on the same horizontal line as the fixing plate 6. When the grinding table 2 moves away from the slide plate 102, due to the elastic return action of the spring 109, the first toothed plate 103 and the second toothed plate 105 can be driven to reset. At this time, the sponge block 106 will continuously approach the pressing plate 7 and contact it. Through the combined action of the fixing plate 6 and the pressing plate 7, the water absorbed by the sponge block 106 can be automatically squeezed out during the reset process of the sponge block 106, so as to ensure that the sponge block 106 can always maintain good water absorption capacity.
