Description

Technical Field

[0001] The invention relates to the technical field of grinding devices, and in particular to a grinding device for casting thin-wall box parts. Background Art

[0002] Cast thin-walled box parts refer to box-shaped parts with thin walls manufactured through a casting process. They are widely used in machinery, automobiles, aviation, electronics, home appliances and other industries. The main function of thin-walled box parts is to serve as a supporting structure or shell, bearing certain loads, protecting internal components or realizing specific functions. Cast thin-walled box parts are prone to burrs at their edges and corners during production, which require personnel to handle.

[0003] During the casting process, if the mold fails to close completely or the molten metal does not flow smoothly, burrs or flash may be generated. These excess parts need to be removed by grinding. For irregularly shaped castings, personnel are required to use manual tools such as files and sandpaper for trimming. Cast thin-walled parts are usually made of fragile materials, and excessively high temperatures can cause deformation or cracks. Therefore, it is particularly important to control the temperature during grinding. At the same time, in order to ensure the grinding effect, personnel are required to use tools alternately to grind the box parts. The grinding of personnel is affected by various factors, resulting in differences in the grinding accuracy between the boxes. Therefore, a grinding device for casting thin-walled box parts is urgently needed to solve the above problems. Summary of the invention

[0044] Before grinding the box body, the box body 6 is placed on the turntable 5 on the receiving platform 10. Starting the electric push rod 3 can drive the push plate 4 to push the box body 6 on the turntable 5 to the placement table 9 to wait for the grinding work to be carried out.

[0045] It also includes a plurality of vertical rods 16, which are fixedly mounted on the operating table 1, and two sliding racks 14 are slidably mounted between every two vertical rods 16. A grinding belt 39 is installed between every two sliding racks 14 on the same horizontal line through a grinding structure. The grinding belt 39 has a certain elasticity, which can make the corners of the box body 6 in the same state after grinding, and will not be damaged by the burrs on the box body 6; the grinding structure is used to grind the burrs at the upper and lower corners of the box body 6 at the same time; the grinding structure includes a fixed arrangement on one of the sliding racks The driving motor 15 on the sliding frame 14 has an incomplete gear 40 fixedly mounted on the driving end of the driving motor 15. The short shaft 1, the short shaft 2 and the short shaft 3 are rotatably mounted on the sliding frame 14. The first gear 41 is fixedly mounted on one end of the short shaft 1, and the second gear 42 is fixedly mounted on one end of the short shaft 2. The first gear 41 is meshed with the incomplete gear 40 and the second gear 42 for use. The third gear 46 is fixedly mounted on one end of the short shaft 3. When the incomplete gear 40 rotates, it is alternately meshed with the first gear 41 and the third gear 46. A connecting shaft 43 is rotatably mounted on the vertical plate. A one-way bearing 50 is installed on the short shaft three, and a belt transmission mechanism is installed between the short shaft two and the one-way bearing 50 and the connecting shaft 43. The belt transmission mechanism includes two pulleys and a belt. It is an existing basic transmission structure and will not be described in detail here. A reverse rotation mechanism is installed between the two sliding frames 14.

A driving shaft 48, a plurality of fixed shafts 52 are fixedly installed on the sliding frame 14, and each fixed shaft 52 is rotatably set in the corresponding driving shaft 48, each fixed shaft 52 and the end close to each rotating shaft are fixedly installed with a limiting rod 49, the end surface shape of the limiting rod 49 is rectangular, and a roller 44 is slidably installed between every two limiting rods 49, one end of the fixed shaft 52 rotatably passes through the corresponding limiting rod 49 and is fixedly installed with a threaded shaft 51, and the roller 44 is threadedly sleeved on the outside of the threaded shaft 51, and the grinding belt 39 is rotatably sleeved between the plurality of rollers 44.

[0046] The upper and lower groups of grinding structures are arranged in a mirror image, and the upper and lower sides of the box body 6 can be polished at the same time. Turning on the driving motor 15 can drive the rotating shaft connected thereto to rotate, and the rotation of the rotating shaft will drive all the rotating shafts to rotate simultaneously through the conveyor belt 45. All the rotating shafts rotate and move at the same time under the action of the threaded shaft 51 and the limiting rods 49 on both sides. The incomplete gear 40 can drive the roller 44 to move from one side to the other side through the rotating shaft and the limiting rod 49 when it is engaged with the third gear 46. Then the incomplete gear 40 is engaged with the first gear 41, and the rotation of the first gear 41 drives the second gear 42 to rotate. The second gear 42 plays a role of reverse rotation, and under the action of the two belt transmission mechanisms, it drives the third gear 46 to rotate in the opposite direction, realizes the rotation of the roller 44, and drives the grinding belt 39 to move left and right while rotating forward and reversely. During this process, one side of the box body 6 can be ground in the forward and reverse directions. Alternating forward grinding and reverse grinding can effectively eliminate scratches left by grinding in a single direction. Grinding along the texture can help refine the surface texture, while reverse grinding can remove small defects, and finally obtain a smoother and brighter effect, simulating the law of manual grinding and improving the grinding effect of the box body 6.

[0047] See also Figure 2 , Figure 4 as well as Figure 5 , and also includes a water tank 8, which is fixedly installed on the operating table 1; and also includes a cooling structure, which is installed between the water tank 8 and the operating table 1, and the high-temperature grinding belt 39 is cooled synchronously under the drive of the grinding structure; the cooling structure includes a water outlet pipe 21 fixedly connected to the water tank 8, and the water outlet pipe 21 cooperates to cool the two grinding belts 39. The water outlet ends of the water outlet pipe 21 are respectively located in the middle position of the upper and lower groups of rollers 44 (each water outlet end is composed of a plurality of water outlet holes), which can cool the inside of the grinding belt 39 (the side opposite to the grinding surface), improve the grinding effect of the grinding belt 39, and prevent the high temperature of grinding from affecting the box body. 6; a plurality of sealing rings 19 are slidingly sleeved on the water outlet pipe 21, a sliding ring 20 is fixedly mounted on each sealing ring 19, and every two sliding rings 20 are rotatably sleeved on the same rotating roller 44, two water receiving trays 17 are fixedly mounted on one side of the operating table 1, and the two water receiving trays 17 are respectively located below the corresponding grinding belts 39, and the two water receiving trays 17 are tilted to receive water flowing out of the water outlet pipe 21, the upper water receiving tray 17 is fixedly connected with two water guide pipes 18, and the lower water receiving tray 17 is fixedly connected with two short pipes, a water collecting tank is opened in the operating table 1, and the lower ends of the two short pipes are connected to the water collecting tank.

[0048] When the grinding belt 39 is grinding the box body 6, the roller 44 drives the sealing ring 19 to move on the water outlet pipe 21 through the sliding ring 20, which can block the corresponding water outlet holes on the water outlet pipe 21 to prevent water from flowing out. While the grinding belt 39 is moving, water is applied synchronously for cooling to improve the cooling effect of the grinding belt 39. The two water receiving trays 17 are arranged at an angle so that the cooled water is directed to be drained under the transition of the water receiving trays 17, the water pipes 18 and the short pipes to lead to the water collection tank; a collection box is arranged in the operating table 1, and the water in the water collection tank is led into the collection box, or a circulating pump is installed on the operating table 1, and the circulating pump is used to suck the water in the water collection tank into the water tank 8 above again, which is convenient for circulating cooling and reduces resource waste.

[0049] See also Figure 1-Figure 4 , Figure 6 , Figure 7 as well as Figure 8 , and also includes a sliding groove, which is opened on the operating table 1, and a sliding plate 22 is slidably installed in the sliding groove, and a back plate 24 is fixedly installed on one side of the sliding plate 22; it also includes a stabilizing structure, which is installed between the back plate 24 and the placement table 9, and is used to limit the relative position of the box 6 during the grinding work to maintain stability during grinding; the stabilizing structure includes connecting plates 13 fixedly installed on both sides of the back plate 24, and a gear rod 12 is fixedly installed on the two connecting plates 13, and two supporting shafts are rotatably installed on the placement table 9, and a gear 11 and two stabilizing bars 7 are fixedly installed on the two supporting shafts, and the gear 11 is respectively meshed with the corresponding gear rod 12, and the same side of multiple stabilizing bars 7 is adapted to the shape of the box 6.

[0050] It also includes a moving structure, which is installed on the operating table 1 and cooperates with the sliding plate 22 to push and pull the two sliding frames 14 in the upper and lower positions, so that the two groups of grinding structures are adjusted to a suitable position of the box 6; the moving structure includes two fixed blocks fixedly installed on the operating table 1, and a rotating rod 47 is installed between the two fixed blocks for common rotation, and a gear 2 36 is fixedly installed on the rotating rod 47, and a gear rod 3 is fixedly provided on the lower surface of the sliding plate 22, and the gear rod 3 is meshed with the gear 2 36 for use. Gears 3 37 are fixedly installed at both ends of the rotating rod 47, and a gear rod 2 38 is fixedly installed on each sliding frame 14, and the two gear rods 2 38 on the same side are meshed with the corresponding gear 3 37 for use.

[0051] The locking structure is also included, which is installed between the sliding plate 22 and the sliding groove to maintain the relative locking of the grinding structure and the stabilizing structure. The locking structure includes two springs 1 23 arranged between the sliding plate 22 and the sliding groove. Two fixing rods 30 are fixedly installed on the side of the sliding plate 22 away from the abutment plate 24. Slide rods are slidably installed on the two fixing rods 30. Wedge-shaped guide blocks 29 are fixedly installed on the ends of the two slide rods close to each other. Springs 28 are installed between the two wedge guide blocks 29 and the corresponding fixing rods 30. A spherical crown body 1 25 is fixedly installed in the sliding groove. A guide rod is fixedly installed on the spherical crown body 1 25. A spherical crown body 26 is fixedly installed on one end of the guide rod. A synthetic spherical crown body 27 is slidably installed on the guide rod. A spring 3 is fixedly installed between the synthetic spherical crown body 27 and the spherical crown body 1 25. The spherical crown body 26 The outer shape of the spherical crown body 1 25 is the same as that of the spherical crown body 25. The side of the spherical crown body 26 close to the synthetic spherical crown body 27 is a hollow setting with the same shape as that of the synthetic spherical crown body 27. When the wedge guide block 29 contacts the spherical crown body 26, the two wedge guide blocks 29 are stuck between the spherical crown body 26 and the synthetic spherical crown body 27 under the action of the spring 28. When the wedge guide block 29 continues to move, it will drive the synthetic spherical crown body 27 to slide in the direction of the spherical crown body 1 25 until it contacts the spherical crown body 1 25. At this time, the two wedge guide blocks 29 are stuck between the spherical crown body 1 25 and the synthetic spherical crown body 27. At this time, the two springs 1 23 drive the two wedge guide blocks 29 to squeeze the synthetic spherical crown body 27 until it fits with the spherical crown body 26, so that the two wedge guide blocks 29 move away from the spherical crown body 26 and the synthetic spherical crown body 27.

[0052] In the initial state (when the box body 6 is not polished), the multiple stabilizing rods 7 and the connecting plate 13 are kept in the same straight line. At this time, the two springs 23 are in a normal state, and the two sets of polishing structures are away from each other. When the box body 6 is polished, the box body 6 is placed on the receiving platform 10, and the electric push rod 3 is started to push the box body 6 onto the placement platform 9. During this process, the box body 6 will be pressed against the abutment plate 24, and the two springs 23 are squeezed by the abutment plate 24 and the sliding plate 22. The movement of the sliding plate 22 drives the two wedge-shaped guide blocks 29 to move in the direction of the spherical crown body 26 until the two wedge-shaped guide blocks 29 are pushed to the gap between the spherical crown body 26 and the synthetic spherical crown body 27. When the abutment plate 24 moves, the two gears 11 are driven to rotate through the two connecting plates 13 and the two gear rods 12. The rotation of the gear 11 drives the stabilizing rod 7 and the two connecting plates 13 to form a vertical angle through the support shaft. , can cooperate with the abutment plate 24 to relatively fix the box body 6 to prevent the box body 6 from shaking during grinding. The side of the multiple stabilizing bars 7 that fits the box body 6 is made of rubber or elastic material (the side of the abutment plate 24 close to the box body 6 is also made of the same material) to prevent damage to the box body 6 when it is relatively fixed, maintaining the stability of the box body 6 while ensuring its integrity; the abutment plate 24 and the sliding plate 22 move while driving the gear rod three to move, and the movement of the gear rod three drives the gear two 36 to rotate, and the rotation of the gear two 36 drives the two gear threes 37 to rotate through the rotating rod 47, and the rotation of the gear three 37 drives the corresponding two gear rods two 38 to approach each other, and drives the two grinding belts 39 to approach the upper and lower edges of the box body 6 through the corresponding two sliding frames 14 until they are tightly attached. At this time, the placement of the box body 6 before grinding is completed, and then the drive motor 15 is turned on to drive the two grinding belts 39 to synchronously grind the box body 6.

[0053] A vertical plate is fixedly installed on one of the sliding frames 14, and a rebound structure used in conjunction with the locking structure is installed between the vertical plate and the abutment plate 24. The rebound structure is used to push the polished box 6 away from the placement table 9. The rebound structure includes a abutment block 31 fixedly installed on the abutment plate 24, and a one-way bearing 2 is rotatably installed on one end of the connecting shaft 43, and the one-way bearing 2 is rotatably set on the vertical plate. A threaded rod 35 is rotatably installed in the one-way bearing 2, and a torsion spring 34 is installed between the threaded rod 35 and the vertical plate. A wedge-shaped slider 32 is threadedly installed on the threaded rod 35, a limit plate 33 is fixedly installed on the vertical plate, and the wedge-shaped slider 32 is slidably set on the limit plate 33.

[0054] When the grinding work on one side of the box body 6 moves in the reverse direction (when the connecting shaft 43 starts to rotate), the connecting shaft 43 drives the threaded rod 35 to rotate, and the rotation of the threaded rod 35 drives the wedge-shaped slider 32 to move until the grinding of one side of the box body 6 is about to be completed, and the wedge-shaped slider 32 reaches the position of the stop block 31, pushing the stop block 31 away from the box body 6. At this time, the stop block 31 drives the sliding plate 22 to squeeze the spring 1 23 through the stop plate 24, so that the two wedge-shaped guide blocks 29 squeeze the synthetic spherical crown 27. When the spring 3 is squeezed to the limit, the two wedge-shaped guide blocks 29 reach the synthetic spherical crown The position between the synthetic spherical crown body 27 and the spherical crown body 1 25, at this time, the single-side grinding of the box body 6 is completed (the connecting shaft 43 no longer rotates), the torsion spring 34 begins to rebound, driving the threaded rod 35 to rotate in the opposite direction, and the rotation of the threaded rod 35 drives the wedge-shaped slider 32 to move back. At this time, under the rebound force of the spring 1 23, the two wedge-shaped guide blocks 29 are driven by the sliding plate 22 and the two fixed rods 30 to squeeze the synthetic spherical crown body 27, so that the synthetic spherical crown body 27 fits in the spherical crown body 26. At this time, the synthetic spherical crown body 27 and the spherical crown body 26 are seamlessly connected, so that the two wedge-shaped guide blocks 29 are separated from the spherical crown body 26. The spring 1 23 is no longer restricted, and the sliding plate 22 drives the plate 24 to push the polished box 6. At the same time, the two connecting plates 13 move with the movement of the plate 24. Under the cooperation of the gear rod 12 and the gear 11, the multiple stabilizing bars 7 are driven to rotate to the initial state (the relationship with the connecting plate 13 is changed from a vertical angle to being on the same straight line). At this time, the box 6 is pushed onto the turntable 5 (the opening time of the electric push rod 3 and the opening time of the rotating motor are set to fixed values. When the electric push rod 3 starts to push the box 6 onto the placement table 9, The time for subsequent work is set at equal intervals. At this time, the polished box 6 arrives on the turntable 5, and the rotating motor is automatically turned on according to the set time, and each time the rotating motor is automatically turned on and off three times, the four sides of the box 6 are automatically polished and paused, which is convenient for personnel to take and place the box 6). At this time, the rotating motor starts, driving the turntable 5 to rotate 90 degrees. At this time, the box 6 rotates 90 degrees, and then the electric push rod 3 is turned on, driving the push plate 4 to push the box 6 to the placement table 9 again, and further polishing of the adjacent sides is carried out. The above cycle completes the uninterrupted automatic polishing of the box 6.
