[0011] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.
[0012] Example 1:
[0013] like Figures 1-3As shown, this utility model discloses a device for grinding burrs on the sidewall of aluminum die-casting parts, including a grinding box 3 and a frame 1. The frame 1 is disposed on the side of the grinding box 3. A grinding roller 4 is disposed inside the grinding box 3. A drive motor 22 is disposed on the sidewall of the grinding box 3, and the drive motor 22 is connected to the grinding roller 4. An opening is provided on the sidewall of the grinding box 3 at the grinding roller 4, and the opening exposes the grinding roller 4 to the outside. The frame 1 is disposed on the side of the grinding box 3 on the side of the opening. The upper end of the frame 1 is a processing platform 2. Several recesses 5 are arranged at intervals on the processing platform 2 near the grinding box 3. Guide rollers 6 are arranged in the recesses 5. The highest end of the guide rollers 6 is flush with or slightly higher than the surface of the processing platform 2. A clamping mechanism is arranged on the processing platform 2 away from the grinding box 3. The clamping mechanism is used to clamp the aluminum die casting 19 and move it on the guide rollers 6. A dust removal pipe 20 is arranged at the lower end of the grinding box 3. A vacuum cleaner 21 is arranged on the dust removal pipe 20.
[0014] The frame 1 can be selected as a frame with a lifting function, which can adjust the relative height of the processing platform 2 and the grinding box 3. The lifting function of the frame 1 is a known existing technology and structure, and this application does not specifically limit it. For example, the processing platform 2 and the frame 1 can be slidably connected and supported by a hydraulic cylinder to adjust the height, or the relative position of the processing platform 2 on the frame 1 can be adjusted by a screw and nut structure. Since the aluminum die-casting part 19 is formed by a mold during actual die casting, burrs are generated at the mold joint, and the burr positions of a batch of similar products are the same. Before deburring, the positions of the processing platform 2 and the grinding roller 4 can be adjusted according to the burr positions on the aluminum die-casting part 19, so that the burrs on the aluminum die-casting part 19 placed on the processing platform 2 correspond to the positions of the grinding roller 4. To improve safety, a clamping mechanism can be used to clamp the aluminum die-casting part 19, and the clamping mechanism drives the movement of the aluminum die-casting part 19 on the processing platform 2. A cavity 5 is provided on the processing platform 2, and a guide roller 6 is arranged inside the cavity 5. The guide roller 6 can rotate freely, and the highest end of the guide roller 6 is flush with the surface of the processing platform 2. Preferably, the highest end of the guide roller 6 is slightly higher than the surface of the processing platform 2, that is, the highest end of the guide roller 6 is 2-3mm higher than the processing platform 2. Of course, the circumferential direction of the guide roller 6 is horizontal. In this way, the aluminum die-cast part 19 placed on the guide roller 6 can slide easily and smoothly on the guide roller 6. Since the guide roller 6 is perpendicular to the grinding roller 4, the aluminum die-cast part 19 can move along the axial direction of the grinding roller 4.
[0015] Of course, if only one aluminum die-cast part 19 is being processed and the location of the burrs is fixed, a fixed frame 1 can be selected, thus determining the relative position of the processing platform 2 and the grinding box 3. If the frame 1 is adjustable, its height can be adjusted before processing a batch of aluminum die-cast parts 19.
[0016] During normal processing, the aluminum die-cast part 19 is placed on the guide roller 6 of the processing platform 2. At this time, the burrs on the aluminum die-cast part 19 correspond to the height position of the grinding roller 4. Then, the two ends of the aluminum die-cast part 19 are clamped using a clamping tool and pushed towards the grinding roller 4, so that the grinding roller 4 contacts the burr part of the aluminum die-cast part 19. The grinding roller 4 is then activated to grind the burrs on the aluminum die-cast part 19. At the same time, the clamping mechanism drives the aluminum die-cast part 19 to move back and forth along the circumference of the grinding roller 4, so as to achieve more stable and uniform grinding of the surface of the aluminum die-cast part 19 and a good burr removal effect. Simultaneously, the vacuum cleaner 21 is activated. After the grinding roller 4 grinds the burrs on the aluminum die-cast part 19 and produces aluminum powder, the vacuum cleaner 21 draws the airflow out of the grinding box 3, resulting in a negative pressure in the grinding box 3. This allows the generated aluminum powder to quickly and directly enter the grinding box 3 and be transported to the vacuum cleaner 21 through the dust removal pipe 20 for collection and reuse.
[0017] The clamping mechanism includes a first guide rod 7 and a first lead screw 8 mounted on the processing platform 2. Both the first guide rod 7 and the first lead screw 8 are parallel to the grinding roller 4. A first sliding plate 10 is mounted on the processing platform 2, slidably connected to the first guide rod 7 and threadedly connected to the first lead screw 8. A first motor 9 is mounted on the side of the frame 1, drivingly connected to the first lead screw 8. A set of guide rails 11 is mounted on the first sliding plate 10, perpendicular to the grinding roller 4. A second sliding plate 13 is mounted on the guide rails 11. An electric push rod 12 is mounted on the first sliding plate 10, connected to the second sliding plate 13, and drives the second sliding plate 13. The slide plate 13 reciprocates on the guide rail 11. Upward protrusions 14 are provided at both ends of the second slide plate 13. A second guide rod 15 and a second lead screw 16 are provided between the two protrusions 14. Both the second guide rod 15 and the second lead screw 16 are parallel to the grinding roller 4. The threads at both ends of the second lead screw 16 are in opposite directions. Clamping arms 17 are provided at both ends of the second guide rod 15 and the second lead screw 16, respectively. The clamping arms 17 are slidably connected to the second guide rod 15 and threadedly connected to the second lead screw 16. The clamping arms 17 extend above the guide roller 6 near the grinding box 3. A second motor 23 is provided on one of the protrusions 14, and the second motor 23 is connected to the second lead screw 16 via a transmission connection.
[0018] The main function of the clamping mechanism is to clamp the aluminum die casting 19 and drive the aluminum die casting 19 closer to the grinding roller 4. At the same time, it can drive the aluminum die casting 19 to move back and forth on the guide roller 6.
[0019] A first lead screw 8 and a first guide rod 7 are installed on the processing platform 2. There can be two first guide rods 7. The first lead screw 8 and the first guide rod 7 are parallel to each other and both are parallel to the grinding roller 4. A first sliding plate 10 is installed on the processing platform 2. To increase installation space, a hollow area can be created on the processing platform 2, and the first guide rod 7 and the first lead screw 8 can be placed within this hollow area. The first sliding plate 10 is slidably connected to the first guide rod 7 and threadedly connected to the first lead screw 8. Therefore, when the first motor 9 drives the first lead screw 8 to rotate, it can drive the first sliding plate 10 to move on the first guide rod 7. A guide rail 11 is installed on the first sliding plate 10, perpendicular to the grinding roller 4. Thus, the electric push rod 12 on the first sliding plate 10 can drive the second sliding plate 13 on the guide rail 11 to slide, thereby pushing the clamping arm 17 and the aluminum die-casting part 19 closer to the grinding roller 4 and maintaining a certain pressure. Simultaneously, in conjunction with the rotation of the first lead screw 8, the second slide plate 13, clamping arm 17, and aluminum die casting 19 can reciprocate together with the first slide plate 10, thereby enabling the aluminum die casting 19 to be deburred at different parts of the grinding roller 4, resulting in a more uniform and stable process.
[0020] A second guide rail 11 and a second lead screw 16 are provided between the protrusions 14 at both ends of the second slide plate 13. The threads at both ends of the second lead screw 16 are opposite. Clamping arms 17 are provided at both ends of the second lead screw 16. When the second motor 23 drives the second lead screw 16 to rotate, the two clamping arms 17 will move closer to each other or further away from each other, thereby enabling the aluminum die casting 19 to be clamped or released.
[0021] Clamping blocks 18 are provided at the inner ends of the two clamping arms 17 facing each other. The clamping blocks 18 are made of rubber.
[0022] To prevent the clamping arm 17 from damaging the surface of the aluminum die casting 19, a clamping block 18, i.e. a rubber block, is provided on the inner side of the clamping arm 17. The rubber block is used to hold the aluminum die casting 19 against it to maintain a stable connection between the aluminum die casting 19 and the clamping arm 17 without causing damage.
[0023] The above solution can remove burrs from the surface of the aluminum die casting 19, and the grinding process can drive the aluminum die casting 19 to move back and forth to improve the stability and uniformity of grinding. The operation process is safe and reliable, and the aluminum powder generated during grinding is removed in time to protect the health of the operators.
