Description

Technical Field

[0001] This utility model relates to the field of aluminum alloy casting grinding technology, specifically to an efficient grinding device for aluminum alloy castings. Background Technology

[0002] Aluminum alloy castings are aluminum alloy products manufactured through a casting process. They are characterized by low density, high specific strength, good corrosion resistance, and excellent casting processability, and are widely used in various fields such as automobiles, machinery, and electronics. After production, aluminum alloy castings often require polishing to achieve a smooth and aesthetically pleasing surface.

[0003] For example, a Chinese patent, CN220660316U, describes a grinding device for aluminum alloy castings, which includes: "an operating table, an L-shaped plate fixedly connected to the top of the operating table, a driven wheel rotatably connected to the bottom of the L-shaped plate, a rotating rod rotatably connected between the bottom surface of the L-shaped plate and the top surface of the operating table, a driving wheel fixedly connected to the outer side of the rotating rod, and the driven wheel and the driving wheel connected by a belt drive; through the cooperation of a servo motor, a rotating rod, a crankshaft, and a connecting rod, a moving block is pushed to slide laterally back and forth along the outer side of a slide rail, so that a relative displacement is formed between the aluminum alloy casting and the grinding disc, and the surface of the aluminum alloy casting is uniformly ground back and forth; at the same time, through the cooperation of the driving wheel, the driven wheel, the mounting base, and the cylinder, the grinding disc is driven to rotate, and through the extension of the cylinder piston rod, the bottom surface of the grinding disc comes into contact with the surface of the aluminum alloy casting, thereby achieving rotary grinding with good grinding effect."

[0004] Through a search of the aforementioned patented technologies, we found that this solution still has the following shortcomings in practical operation:

[0005] On the one hand, the existing technology can only grind one aluminum alloy casting at a time. The next casting can only be installed and ground after the current casting has been ground and removed. The grinding efficiency of the casting is relatively low. Furthermore, during grinding, the casting can only move in one direction on the moving block, meaning that only the position in the direction of the casting's movement can be ground, making it difficult to grind other positions of the casting.

[0006] On the other hand, when the aforementioned prior art grinds castings, the grinding station is exposed to the outside, and the dust generated during grinding is easily blown around in the workshop, thus affecting the workshop environment and the health of the workers.

[0007] Therefore, in response to the technical problems mentioned above in the existing technology, we have designed a high-efficiency grinding device for aluminum alloy castings. Utility Model Content

[0013] As a further embodiment of this utility model: the top of the grinding box is fixed with a top cover by bolts, an electric push rod is installed on the top cover, the power output shaft of the electric push rod passes through the interior of the grinding box and is fixed with a fixing plate, a grinding motor is installed at the bottom of the fixing plate, a grinding disc is installed on the power output shaft of the grinding motor, and limit rods are fixed at the four corners of the top of the fixing plate, the top of the limit rods all movably pass through to the top of the top cover.

[0014] As a further embodiment of this utility model: the end of the second suction pipe away from the filter box extends into the interior of the grinding box and is connected to a suction hood, the position of which corresponds to the position of the grinding disc.

[0015] As a further embodiment of this utility model: one side of the filter box is an open structure, and a sealing plate is fixed to the opening by bolts.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Example 1, please refer to Figure 1-5 A high-efficiency grinding device for aluminum alloy castings includes a grinding box 1, a support plate 3, and an aluminum alloy casting 20. Movable openings 2 are provided on both the front and rear sides of the grinding box 1. A movable plate 6, driven by a servo motor 5 and moving longitudinally, is slidably connected between the inner bottom wall of the grinding box 1 and the top of the support plate 3. A clamping assembly 7, driven by a servo motor 10 and moving laterally, is slidably connected to the top of the movable plate 6. The clamping assembly 7 includes a movable plate 701 and a clamping block 704 disposed on the top of the movable plate 701 for clamping the aluminum alloy casting 20. A vacuum cleaner 14 is installed at the bottom of the grinding box 1. A filter box 15 is fixed on one side of the grinding box 1. The bottom of the filter box 15 is connected to the vacuum cleaner 14 through a first suction pipe 1401. The top of the filter box 15 is connected to the inside of the grinding box 1 through a second suction pipe 1501. The end of the second suction pipe 1501 away from the filter box 15 passes through the inside of the grinding box 1 and is connected to a dust hood 1502. The position of the dust hood 1502 corresponds to the position of the grinding disc 13. The dust hood 1502 is close to the grinding position and can immediately extract the dust generated during grinding.

[0032] Please see Figure 1 , Figure 2 and Figure 3 Furthermore, the support plate 3 is fixed to the bottom of one side of the grinding box 1. A limiting groove 4 is provided between the top of the support plate 3 and the inner bottom wall of the grinding box 1. A limiting slider 601 is provided at the bottom of the movable plate 6, and the limiting slider 601 is slidably connected in the limiting groove 4. The servo motor 5 is installed on the side of the support plate 3. The power output shaft of the servo motor 5 moves through the limiting groove 4 and is connected to the lead screw 501. The end of the lead screw 501 away from the servo motor 5 is threaded through the limiting slider 601 and rotatably connected to the inner wall of the other side of the limiting groove 4.

[0033] Specifically, after the servo motor 5 starts, the rotation of the lead screw 501 drives the limiting slider 601, which is threaded onto it, to slide in the limiting groove 4. Since the support plate 3 and the grinding box 1 share a limiting groove 4, the limiting slider 601 can move easily on the support plate 3 or the inner bottom wall of the grinding box 1, thereby synchronously driving the movable plate 6 to move on the support plate 3 or inside the grinding box 1, thereby driving the aluminum alloy casting 20 on the top of the movable plate 6 to move in the longitudinal direction.

[0034] Please see Figure 2 , Figure 3 and Figure 4 Furthermore, the clamping assembly 7 also includes two fixing blocks 702. Each fixing block 702 has an adjusting screw 703 threadedly connected to the middle of its side. One end of each adjusting screw 703 is rotatably connected to a clamping block 704. A rubber sheet is glued to the side of the clamping block 704 away from the adjusting screw 703.

[0035] Specifically, when the aluminum alloy casting 20 to be ground is placed on the movable plate 2 701, the clamping blocks 704 can be pushed by turning the two adjusting screws 703 on the movable plate 2 701, so that the two clamping blocks 704 can clamp the two sides of the aluminum alloy casting 20 and fix it. The clamping blocks 704 have rubber sheets, which can improve the stability after clamping and avoid damage to the aluminum alloy casting 20.

[0036] Please see Figure 2 , Figure 3 and Figure 4 Furthermore, a limiting groove 602 is provided at the top of the movable plate 6 and at the bottom of the movable plate 701. A limiting slider 7011 is fixed at the bottom of the movable plate 701, and the limiting slider 7011 is slidably connected in the limiting groove 602. A servo motor 10 is installed on one side of the movable plate 6, and the power output shaft of the servo motor 10 moves through the limiting groove 602 and is connected to a lead screw 1001. The end of the lead screw 1001 away from the servo motor 10 passes through the limiting slider 7011 and is rotatably connected to the inner wall of one side of the limiting groove 602.

[0037] Specifically, by starting the servo motor 10, the lead screw 1001 can be rotated. The rotation of the lead screw 1001 causes the limiting slider 7011, which is threaded onto it, to slide in the limiting groove 602. When the limiting slider 7011 slides, it can cause the movable plate 701, which is fixed to it, to move laterally at the top of the movable plate 6. This causes the aluminum alloy casting 20 at the top of the movable plate 701 to move laterally, thus achieving the grinding of the aluminum alloy casting 20 in the lateral direction.

[0038] Please see Figure 1 , Figure 2 and Figure 3 Furthermore, the top of the grinding box 1 is fixed with a top cover 8 by bolts. An electric push rod 9 is installed on the top cover 8. The power output shaft of the electric push rod 9 passes through the interior of the grinding box 1 and is fixed with a fixing plate 11. A grinding motor 12 is installed at the bottom of the fixing plate 11. A grinding disc 13 is installed on the power output shaft of the grinding motor 12. Limiting rods 1101 are fixed at the four corners of the top of the fixing plate 11. The top of the limiting rods 1101 can be moved through to the top of the top cover 8.

[0039] Specifically, the top cover 8 is fixed to the top of the grinding box 1 with bolts, which facilitates subsequent disassembly and allows for easy maintenance or cleaning of the interior of the grinding box 1. The activation of the electric push rod 9 can drive the fixed plate 11 to move up and down, thereby adjusting the height of the grinding motor 12 and the grinding disc 13. This allows for easy grinding of aluminum alloy castings 20 of different thicknesses. When the fixed plate 11 is in motion, it is limited and guided by the limit rod 1101, which helps to improve the stability of the fixed plate 11 during movement, thereby ensuring the stability of the grinding motor 12.

[0040] Please see Figure 4 and Figure 5 Furthermore, one side of the filter box 15 has an open structure, and a sealing plate 16 is fixed to the opening by bolts. A sealing film 19 is provided at the connection between the sealing plate 16 and the filter box 15. A filter screen 17 and a filter screen 18 placed inside the filter box 15 are fixed to one side of the sealing plate 16. The mesh size of the filter screen 17 is larger than that of the filter screen 18.

[0041] Specifically, the filter box 15 contains filter screen 17 and filter screen 18, which can achieve stratified filtration of dust particles of different sizes. Filter screen 17 filters larger dust particles, while filter screen 18 filters smaller dust particles, resulting in better dust filtration. Filter screen 17 and filter screen 18 are fixed to the sealing plate 16. One side of the sealing plate 16 is sealed to the filter box 15 by a sealing film 19. This allows for easy disassembly of the sealing plate 16 for cleaning of the two filters and ensures a tight seal after connection using the sealing film 19.

[0042] Please see Figure 1 , Figure 2 and Figure 3 Furthermore, the top of the movable plate 6 is provided with multiple limiting slide grooves 602, and the top of each limiting slide groove 602 is provided with a movable plate 701. The top of each movable plate 701 is provided with a set of clamping components 7, and each movable plate 701 is driven by a servo motor 10.

[0043] Specifically, the top of the movable plate 6 is equipped with multiple sets of clamping components 7, which allows multiple aluminum alloy castings 20 to be loaded on the top of the movable plate 6 at the same time and to be ground one by one at the bottom of the grinding disc 13. This grinding method is more efficient. After multiple aluminum alloy castings 20 are ground, they can be disassembled and assembled at the same time. Compared with the current technology, which can only grind one aluminum alloy casting 20 at a time and requires the current casting to be ground and removed before the next casting can be installed and ground, this method is more efficient.

[0044] Example 2, please refer to Figure 6 Dust curtains 201, composed of multiple transparent plastic strips, are installed at the movable openings 2 on both the front and rear sides of the grinding box 1. The design of the movable openings 2 facilitates the movement of the movable plate 6 within the grinding box 1. The dust curtains 201 at the movable openings 2 provide a certain degree of shielding, reducing the possibility of dust overflowing from inside the grinding box 1. Combined with the cover of the grinding box 1 and the dust extraction hood 1502, the dust generated during grinding can be better handled. The dust curtains 201 are made of soft plastic strips and will not affect the entry and exit of the movable plate 6.

[0045] When in use, the operator can start the servo motor 5, thereby using the lead screw 501 to drive the movable plate 6 to the top of the support plate 3. Then the operator can place the aluminum alloy casting 20 to be polished on the multiple movable plates 6 in sequence, and push the clamping block 704 to clamp the side of the aluminum alloy casting 20 by turning the adjusting screw 703, so as to stabilize the aluminum alloy casting 20 on the movable plate 6.

[0046] Then, servo motor 5 is started, driving one side of movable plate 6 to move (longitudinally) into the grinding box 1, so that the aluminum alloy casting 20 on movable plate 701 comes to the bottom of the grinding disc 13. Through the rotation of the grinding disc 13, the longitudinal position of the surface of the aluminum alloy casting 20 is ground. Then, the corresponding servo motor 10 is started. The power output shaft of servo motor 10 drives the lead screw 1001 to rotate, thereby driving movable plate 701 to move laterally on the top of movable plate 6. When movable plate 6 moves laterally, it can drive the aluminum alloy casting 20 to move laterally, thereby cooperating with the action of grinding disc 13 to grind the lateral position of aluminum alloy casting 20.

[0047] During the polishing process, since the dust hood 1502 is close to the polishing position, the dust generated during polishing can be drawn by the vacuum cleaner 14 and transported to the filter box 15 through the dust hood 1502 and the second suction pipe 1501 for filtration. The air with the dust removed is transported to the vacuum cleaner 14 through the first suction pipe 1401 and discharged. This achieves the purpose of immediate suction of the dust generated during polishing and the purpose of filtering the suctioned dust.

[0048] Since the top of the movable plate 6 has multiple sets of clamping components 7, each set of clamping components 7 can move one by one to the bottom of the grinding disc 13 through the movement of the movable plate 6. The grinding disc 13 can then grind the aluminum alloy castings 20 held by the multiple sets of clamping components 7 one by one. After all the aluminum alloy castings 20 held by the multiple sets of clamping components 7 have been ground, the grinding motor 12 and the vacuum cleaner 14 can be turned off, and the servo motor 5 can be used to drive the movable plate 6 back to the top of the support plate 3, so as to remove the aluminum alloy castings 20 that have been ground on the movable plate 6.

[0049] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
