Description

Technical Field

[0001] This utility model relates to the field of aluminum die casting polishing technology, and in particular to an aluminum die casting surface polishing device. Background Technology

[0002] In modern manufacturing, aluminum die castings are widely used in various fields such as automobiles, aerospace, and electronic equipment due to their lightweight, high strength, and excellent mechanical properties. To ensure the surface quality and dimensional accuracy of aluminum die castings, grinding is an essential step. However, in traditional grinding processes, the friction between the high-speed rotating grinding tool and the workpiece surface generates a large amount of heat, which can lead to workpiece overheating, causing material deformation or a decrease in surface quality. Furthermore, if the debris generated during grinding is not removed promptly, it will not only affect the grinding effect but may also further exacerbate localized overheating.

[0003] Many grinding machines on the market lack effective cooling and debris removal systems, leading to increased workpiece surface temperature during prolonged continuous operation, affecting machining accuracy and surface quality. While some existing solutions attempt to reduce temperature through external cooling methods (such as fans), these methods are inefficient and cannot effectively control the temperature distribution across the entire workpiece surface. Simultaneously, debris accumulation causes wear on grinding tools, increases maintenance costs, and may pose safety risks.

[0004] To address the aforementioned issues, this invention proposes a surface grinding device for aluminum die-cast parts. This grinding device integrates a spray cooling system and a debris removal function, which can effectively prevent workpiece overheating and deformation while ensuring high-quality grinding results, thereby improving production efficiency, reducing maintenance costs, and enhancing operational safety. Summary of the Invention

[0005] To overcome the drawbacks of high-speed rotating grinding tools generating excessive heat through friction with the workpiece surface, leading to overheating, material deformation, or decreased surface quality, and the potential for further exacerbation of localized overheating if debris is not removed promptly during grinding, this invention provides a grinding device for aluminum die-cast parts. This device integrates a spray cooling system and a debris removal function, effectively preventing workpiece overheating and deformation while ensuring high-quality grinding results, improving production efficiency, reducing maintenance costs, and enhancing operational safety.

[0007] Optionally, the spray assembly includes a loading frame, which is fixedly connected to the support base. A detachable screening frame is slidably connected to the loading frame. A spray box is fixedly connected to the top of the cover frame. A connecting pipe connects the spray box and the loading frame, and a water pump is fixedly connected to the connecting pipe.

[0008] Optionally, the dust removal assembly includes laterally symmetrical dust collection boxes, which are fixedly connected to a support base.

Detailed Implementation

[0021] References to embodiments herein mean that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of the present invention. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0022] Example 1: A surface grinding device for aluminum die castings, such as Figures 1-7As shown, the system includes a support base 1, a cover frame 2, a conveyor belt 3, a guide plate 4, a sliding frame 5, an elastic element 51, a motor 6, a grinding wheel 7, a support plate 71, a backing plate 8, a wiping wheel 81, a spray assembly, and a chip removal assembly. The cover frame 2 is fixedly connected to the support base 1. Equally spaced baffles are provided on both sides of the cover frame 2 to prevent chip splashing. The front and rear parts of the support base 1 are rotatably connected to the conveyor belt 3 via conveyor rollers. Equally spaced positioning blocks are fixedly connected to the conveyor belt 3. A symmetrically arranged guide plate 4 is fixedly connected to the middle of the support base 1. A sliding frame 5 is slidably connected between the front and rear guide plates 4. The front and rear ends of the sliding frame 5 are connected to the adjacent guide plates 4. The sliding frame 5 has symmetrical elastic elements 51. A motor 6 is fixedly connected to the rear side of the sliding frame 5. A grinding wheel 7 is rotatably connected to the sliding frame 5. The grinding wheel 7 is fixedly connected to the output shaft of the motor 6. A support plate 71 is fixedly connected between the middle of the front and rear guide plates 4. The support plate 71 passes through the interior of the front and rear conveyor belts 3 and is located below the grinding wheel 7. A backing plate 8 is fixedly connected to the right side of the sliding frame 5. The backing plate 8 is inclined and used to press and cooperate with the aluminum die casting. A wiping wheel 81 is rotatably connected to the left side of the backing plate 8. A spray assembly for spraying and cooling the aluminum die casting is provided on the support base 1 and the cover frame 2. A chip cleaning assembly for cleaning the grinding debris on the aluminum die casting is provided on the support base 1.

[0023] When using this device, the operator places the aluminum die-casting part to be polished on the front and rear conveyor belts 3 and positions it using positioning blocks. Then, the conveyor belts 3 move the aluminum die-casting part to the left. When the aluminum die-casting part moves to the left and contacts the abutment plate 8, it will squeeze the abutment plate 8 upward. The upward movement of the abutment plate 8 causes the sliding frame 5 to slide upward, and the elastic element 51 deforms. The upward movement of the sliding frame 5 causes the motor 6 and the grinding wheel 7 to move upward, so that the grinding wheel 7 adapts to the height of the aluminum die-casting part and maintains contact with the surface of the aluminum die-casting part. The motor 6 drives the grinding wheel 7 to rotate and polish the surface of the aluminum die-casting part. Before the aluminum die-casting part moves and contacts the grinding wheel 7, the wiping wheel 81 can first clean the surface of the aluminum die-casting part. During the polishing process, the spray assembly can spray the grinding wheel 7 and the aluminum die-casting part to cool them down, while the chip removal assembly can remove the chips generated by the grinding wheel 7, so as to avoid affecting the polishing effect and further prevent overheating.

[0024] Example 2: Based on Example 1, such as Figure 1 , Figure 4 and Figure 5As shown, the spray assembly includes a loading frame 9, a screening frame 10, a connecting pipe 11, a water pump 12, and a spray box 13. The loading frame 9 is fixedly connected inside the support base 1. The detachable screening frame 10 is slidably connected to the upper side of the loading frame 9. The spray box 13 is fixedly connected to the middle of the upper side of the cover frame 2. The front side of the spray box 13 is connected to the front side of the loading frame 9 by a connecting pipe 11. The lower part of the connecting pipe 11 is fixedly connected to the water pump 12.

[0025] When using this device, water in the spray box 13 sprays out from the bottom to cool the grinding wheel 7 and the aluminum die casting. The sprayed water flows downward into the loading frame 9, where it is filtered by the screening frame 10 to intercept and filter the entrained debris. The water pump 12 operates to pump the water in the loading frame 9 back into the spray box 13 through the connecting pipe 11 for spraying. In this way, the grinding wheel 7 and the aluminum die casting can be cooled by spraying, preventing the grinding wheel 7 and the aluminum die casting from overheating, which could lead to material deformation or a decrease in surface quality.

[0026] like Figure 6 and Figure 7 As shown, the dust removal assembly includes a dust collection box 14, a dust pump 141, a suction frame 142, and a drying wheel 15. The dust collection boxes 14 are fixedly connected to the middle of the upper side of the support base 1. The dust collection box 14 is connected to the dust pump 141, and the suction frame 142 is connected to the dust pump 141. The drying wheel 15 is rotatably connected to the dust collection box 14 on the left side.

[0027] When using this device, the dust pump 141 operates to control the suction frame 142 to suck up dust and debris from both sides of the grinding wheel 7, preventing debris from accumulating on the aluminum die casting, which would cause unevenness or scratches on the surface of the aluminum die casting, affecting the quality of grinding. In addition, debris accumulation will also cause heat to accumulate, increasing the temperature of the aluminum die casting and the grinding wheel 7, affecting material properties, and even causing deformation or burns. The sucked debris enters the dust collection box 14 for collection. After the aluminum die casting is ground, the aluminum die casting continues to move to the left and will be wiped by the drying wheel 15, thereby drying the water stains on the surface of the aluminum die casting.

[0028] The above embodiments are only for illustrating the technical concept and features of this utility model, and are intended to enable those skilled in the art to understand the content of this utility model and implement it accordingly. They should not be construed as limiting the scope of protection of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be included within the scope of protection of this utility model.
