Description

Technical Field

[0001] This invention relates to the field of casting grinding and polishing technology, specifically to a grinding device for stainless steel metal castings used in building processing. Background Technology

[0002] Stainless steel drain covers are grid-shaped or perforated covers made of stainless steel that are installed at the inlets of various drainage ditches and drains on construction sites. Their core functions are drainage, filtering of impurities, load-bearing passage, and ensuring construction safety and site cleanliness.

[0003] Existing stainless steel metal casting grinding equipment has significant limitations in practical use. Currently, existing equipment only relies on grinding blocks to grind the two outer surfaces of stainless steel drain covers. However, this single grinding method cannot effectively remove surface burrs. This is because, during the production process of stainless steel drain covers, several holes are formed on the surface through a stamping process to enable drainage and filtration. When the punch penetrates the material, the metal near the fracture surface is subjected to tensile stress and will uncontrollably turn outward or tear towards the edge of the hole, thus forming burrs. These burrs are not only distributed on the outer surface of the drain cover, but also widely present in areas such as the edges of the holes. Therefore, grinding only the outer surface of the drain cover can only remove some of the burrs, while it is difficult to deal with the burrs at the edges of the holes and inside the holes, resulting in incomplete deburring and ultimately affecting the quality of the product and its subsequent use. Summary of the Invention

[0019] Second, by linking the clamping and rotating component with the support plate, the stainless steel drain cover automatically flips 180° after the first outer surface grinding and hole edge grinding are completed, preparing for the next second outer surface grinding. This integrates the original manual flipping process into an automated process, avoiding intermittent waiting time and improving production efficiency.

[0020] Third, this invention uses a high-speed rotating grinding belt to precisely penetrate the edges and inside the holes of stainless steel drain covers, effectively removing internal stamping burrs that are difficult to reach with traditional single-surface grinding, improving grinding quality, ensuring the precision and smoothness of the punched parts of the stainless steel drain cover, and improving the overall quality of the product.

[0034] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0035] Example 1, please refer to Figures 1 to 12 This invention provides a grinding device for stainless steel metal castings in building processing.

[0036] More specifically, in this embodiment: it includes a processing table 1 and a mounting cavity 2. A rack 3 is slidably connected to the inner wall of the mounting cavity 2. A hinge 44 is rotatably connected to the surface of the rack 3. A movable plate 4 is rotatably connected to the end of the hinge 44. The movable plate 4 is slidably connected to the inner wall of the mounting cavity 2. A movable plate 5 is fixedly connected to one side of the rack 3 through a transmission rod assembly. A blocking block 6 and a flipping toothed plate 7 are provided inside the mounting cavity 2. A support plate 8 is slidably connected inside the processing table 1. A clamping frame 9 is rotatably connected to the support plate 8. Several grinding belts 10 are provided inside the processing table 1. Grinding components are provided inside the processing table 1.

[0037] The grinding components include:

[0038] The process interlocking component, by moving the support plate 8, presses the moving plate 4, causing the rack 3 to move and push out the blocking block 6, thus preventing the grinding part from not completing the grinding process.

[0039] The clamping and rotating component is pressed against the moving plate 5 by the horizontal movement of the support plate 8, causing the rack 3 to move in another direction and push out the flipping toothed plate 7, driving the clamping frame 9 to hold the grinding part and flip it 180°.

[0040] The finishing parts are cleaned by the high-speed rotation of the grinding belt 10 to remove burrs from the edges of the holes in the grinding parts;

[0041] The process interlocking components include a sliding frame 11, two push blocks 12, and two slots. The sliding frame 11 is fixedly installed on the top of the inner wall of the mounting cavity 2. A slider 13 is slidably connected inside the sliding frame 11, and a spring 14 is fixedly connected inside the slider 13. A blocking block 6 is fixedly connected to the other end of the spring 14, and a pulling rod 15 is fixedly connected to the other end of the slider 13. A fixing groove 16 is provided on the slider 13, and a fixing component is provided in the fixing groove 16. The two push blocks 12 are fixedly installed on the back of the rack 3, and the two slots are respectively opened at the top and bottom of the mounting cavity 2. The pull rod 15 is slidably inserted between the two slots 1. The fixing assembly includes a threaded cylinder 17 and two slots 2. The threaded cylinder 17 is rotatably installed in the mounting cavity 2. The threaded cylinder 17 is internally threaded with a threaded rod 18. One end of the threaded rod 18 is fixedly connected to a fixing block 19. A limit rod 20 is fixedly connected to the fixing block 19. A gear 21 is fixedly sleeved on the outer surface of the threaded cylinder 17. The gear 21 meshes with the rack 3. The two slots 2 are respectively opened at the top and bottom of the inner wall of the mounting cavity. The limit rod 20 is slidably inserted between the two slots 2.

[0042] A drive motor 2 36 is fixedly installed on the processing table 1. The output end of the drive motor 2 36 is fixedly connected to a threaded rod 37. A horizontal plate 38 is fixedly connected to the outer surface of the threaded rod 37. A threaded rod 4 39 is threadedly connected to the horizontal plate 38. Rotating wheels 5 are fixedly fitted on the outer surfaces of both the threaded rod 4 39 and the threaded rod 37. The two rotating wheels 5 are connected by a belt 3. A drive motor 3 40 is fixedly connected to the horizontal plate 38. The output end of the drive motor 3 40 is fixedly connected to a threaded rod 5 48. A support block 41 is threadedly connected to the outer surface of the threaded rod 5 48. The top of the support block 41 is fixedly connected to the support plate 8. The support block 41 is slidably connected to the surface of the horizontal plate 38. The threaded rod 49 is rotatably connected to the horizontal plate 38. An installation cavity 2 42 is opened inside the processing table 1. The horizontal plate 38 is slidably connected to the installation cavity 2 42. Two moving slots 43 are opened inside the processing table 1. The support plate 8 moves through the two moving slots 43. A grinding machine body 45 is set inside the processing table 1.

[0043] In the initial state, the moving plate 4 is under pressure, and the fixing block 19 is inserted into the fixing groove 16, making the slider 13 fixed. When using this stainless steel metal casting grinding device for building processing, the operator first inserts the stainless steel drain cover to be ground into the clamping frame 9 and tightens the bolts on the frame, driving the clamping plate to move down to fix the workpiece. After fixing, the workpiece is transported to the bottom of the grinding machine body 45. By starting the drive motor 40, its output end drives the threaded rod 48 to rotate, thereby pushing the support block 41, support plate 8, clamping frame 9 and workpiece together to move down the grinding machine body 45. The middle support block 41 slides along the surface of the horizontal plate 38, and when the support plate 8 moves to contact the blocking block 6, it will press the blocking block 6 into the slider 13 along its guide surface. At the same time, the spring 14 is compressed to store energy until the workpiece reaches the bottom of the grinding machine body 45. At this time, the support plate 8 and the blocking block 6 are completely separated, and the spring 14 releases energy and pushes out the blocking block 6. Since the contact surface between the blocking block 6 and the support plate 8 changes from an inclined surface to a plane at this time, if the workpiece tries to return after grinding, it will be blocked by the blocking block 6. In this way, the blocking block 6 forms a forced barrier to remind the operator that the overall processing process is not yet complete.

[0044] After the outer surface grinding is completed, the drive motor 2 36 can be started again. Its output end drives the threaded rod 37 and the threaded rod 4 39 to rotate synchronously, so that the horizontal plate 38 moves the support block 41, the support plate 8 and the workpiece to the bottom of the grinding belt 10. During this process, the end of the movement path of the support plate 8 will push the moving plate 2 5, and through the transmission rod group, the rack 3 will move away from the blocking block 6, and then the hinge 44 will pull the moving plate 1 4 to reset.

[0045] During the movement of rack 3, drive gear 21 will rotate. The rotation of gear 21 will drive threaded cylinder 17, causing threaded rod 18 to move under the limit of slot 2. As a result, fixed block 19 will disengage from fixed slot 16, releasing the lock on slider 13. As rack 3 continues to move, push block 12 on it, away from hinge 44, will contact pull rod 15 and push it to move. Under the limit of slot 1, pull rod 15 will pull slider 13 and blocking block 6 back into sliding frame 11. At this time, blocking block 6 will be removed from the original path to make way for the return of the polished workpiece.

[0046] After the workpiece is processed at the station below the grinding belt 10, the second drive motor 36 can be rotated in the opposite direction to send the workpiece back to the previous process. Then the third drive motor 40 is started to flip the workpiece so that it moves from below the grinding machine body 45 to the initial position and completes the reset. In this reset path, since the blocking block 6 has been removed from the original path, it will no longer obstruct the reset process of the workpiece.

[0047] It is worth noting that after the reset is completed, the support plate 8 will press the moving plate 4. At this time, the movement of the moving plate 4 will pull the hinge 44 to move synchronously. Since the hinge 44 is in an inclined state, the movement of the hinge 44 will pull the rack 3 to move closer to the blocking block 6. The rack 3 drives the gear 21 and the gear 26 to rotate. At the same time, the rack 3 drives the moving plate 5 to move towards the blocking block 6 through the transmission rod group. Meanwhile, the gear 21 drives the threaded cylinder 17 to rotate. As the rack 3 moves, the other pushing block 12 close to the hinge 44 abuts against the pulling rod 15 and pushes it to move synchronously. Under the limit of the slot 1, the pulling rod 15 drives the slider 13 and the blocking block 6 to extend the sliding frame 11. Under the limit of the slot 2, the threaded rod 18 drives the fixing block 19 and the limiting rod 20 to approach the fixing slot 16 to fix the slider 13, so that the blocking block 6 returns to the blocking position. Similarly, the movement of the rack 3 also drives the moving plate 5 to reset.

[0048] The above method ensures that during the processing of castings, when only one side of the grinding is completed, normal resetting and removal are not possible. The castings must be moved under the grinding belt 10 and processed by the grinding belt 10 before normal resetting and completion of the grinding work. This measure can fundamentally avoid the situation where the grinding process is reduced due to operator negligence, and the product is removed before the process is fully completed, thus preventing defective castings from entering the market due to operator negligence.

[0049] Example 2, based on the above examples:

[0050] Please see Figures 7 to 9 The clamping and rotating component includes a mounting plate 22, a first rotating shaft 23, a second rotating shaft 24, and a third rotating wheel. The mounting plate 22 is fixedly installed inside the mounting cavity 2. A second threaded cylinder 25 is rotatably connected to the mounting plate 22. A second gear 26 is fixedly sleeved on the outer surface of the second threaded cylinder 25. A second threaded rod 27 is threadedly connected inside the second threaded cylinder 25. Two second limiting rods 28 are fixedly connected to the back of the mounting plate 22. The first rotating shaft 23 and the second rotating shaft 24 are both rotatably installed on the support plate 8. A flipping wheel 29 is fixedly sleeved on the outer surface of the first rotating shaft 23. The first rotating shaft 23 and the second rotating shaft 24 are connected by a pulley assembly 1. The second rotating shaft 24 is connected by a pulley assembly 2 to a rotating shaft on the clamping frame 9. The second gear 26 meshes with the rack 3. The flipping gear plate 7 is fixedly connected to the back of the second threaded rod 27. The flipping gear plate 7 is slidably connected to the two second limiting rods 28.

[0051] More specifically, in this embodiment: during the above process, when the support plate 8 pushes the moving plate 2 5 to move, the rack 3 not only drives the gear 1 21 to rotate, but also drives the gear 2 26 to rotate. The rotation of the gear 2 26 drives the threaded cylinder 2 25 to rotate, so that the threaded rod 2 27 pushes the flipping toothed plate 7 to move forward to the slide rail 47 under the guidance of the limiting rod 2 28, in preparation for the subsequent flipping action of the clamping frame 9.

[0052] During the process of the casting being processed by the grinding belt 10 and returning to its original position, the flipping wheel 29 on the clamping frame 9 will engage with the already positioned flipping toothed plate 7 during its movement. This causes the flipping wheel 29 to drive the clamping frame 9 and the workpiece inside it to rotate 180° during the resetting process via the rotating shaft on the clamping frame 9, so that the other unpolished outer surface faces upward and towards the grinding machine body 45. This allows the casting to be polished when it is reset to below the grinding machine body 45, thus completing the double-sided polishing process of the casting. During the process of the casting being reset to its initial position, i.e., during the pressing of the moving plate 4, the flipping toothed plate 7 resets synchronously.

[0053] Example 3, based on the above examples:

[0054] Please see Figures 10 to 11 The finishing component includes a hydraulic telescopic rod 30 fixedly installed on the top of the processing table 1. The telescopic end of the hydraulic telescopic rod 30 is fixedly connected to a lifting plate 31. A drive motor 32 is fixedly connected to one side of the lifting plate 31. The output end of the drive motor 32 is fixedly connected to a worm gear 33. Several rotating shafts 34 and 45 are rotatably connected to the bottom of the lifting plate 31. Worm wheels 46 are fixedly sleeved on the outer surface of each of the rotating shafts 34 and 45. Rotating wheels 4 are fixedly sleeved on the outer surface of each of the rotating shafts 34 and 45. Two rotating wheels 4 are connected by a grinding belt 10. The worm gear 33 is rotatably connected to the lifting plate 31, and the worm gear 33 meshes with the worm wheel 46.

[0055] More specifically, in this embodiment: when the stainless steel floor drain moves to the fine grinding station, the drive motor 32 and the hydraulic telescopic rod 30 are started. The output end of the drive motor 32 drives the worm gear 33 to rotate, which in turn drives the worm wheel 46 and the rotating shaft 34 to rotate. The rotating shaft 34 drives the rotating shaft 45 to rotate through the grinding belt 10. The telescopic end of the hydraulic telescopic rod 30 drives the lifting plate 31 and the high-speed rotating grinding belt 10 to approach the workpiece and perform fine grinding on the burrs on the edges of the holes and other key parts.

[0056] Working principle: In the initial state, the moving plate 4 is in a compressed state, and the fixed block 19 has been inserted into the fixed groove 16, so that the slider 13 is in a fixed state.

[0057] When using the stainless steel metal casting grinding device for building processing, the worker first inserts the stainless steel drain cover to be ground into the clamping frame 9, tightens the bolts on the frame, and drives the clamping plate to move down to fix the workpiece.

[0058] After fixing, the workpiece is transported to the bottom of the grinding machine body 45. By starting the drive motor 40, its output end drives the threaded rod 48 to rotate, thereby pushing the support block 41, support plate 8, clamping frame 9 and workpiece together to move towards the grinding machine body 45. During this process, when the support plate 8 moves to contact the blocking block 6, it will press the blocking block 6 into the slider 13 along its guide surface. At the same time, the spring 14 is compressed to store energy. When the workpiece reaches the outer surface grinding station, the support plate 8 and the blocking block 6 are completely separated. The spring 14 then releases energy and pushes out the blocking block 6, thus forming a forced barrier. If the workpiece attempts to return after grinding only one surface, it will be blocked by the blocking block 6, thus effectively reminding the operator that the current process has not been completed.

[0059] Once the outer surface grinding is finished, drive motor 2 36 is started. Its output end drives threaded rod 3 37 to rotate, which in turn drives a pair of rotating wheels 5 and, through belt 3 linkage, makes threaded rod 4 39 rotate synchronously. Finally, the horizontal plate 38 drives the support block 41, support plate 8 and workpiece to the next process.

[0060] When the support plate 8 moves to abut against the moving plate 5, it will push the moving plate 5 and the rack 3 connected by the transmission rod group to move away from the blocking block 6. The rack 3 will then drive the gear 1 21 and the gear 2 26 to start rotating. The rotation of the gear 1 21 will drive the threaded cylinder 17, causing the threaded rod 18 to move under the limit of the slot 2, thereby the fixed block 19 will disengage from the fixed slot 16 and release the lock on the slider 13. At the same time, the gear 2 26 will push the flipping toothed plate 7 to move forward to the slide rail 47 under the guidance of the limit rod 28 through the threaded cylinder 25 and the threaded rod 27, preparing for the subsequent flipping action. In addition, as the rack 3 continues to move, one of its push blocks 12 will contact the pull rod 15 and push it to move, so that the pull rod 15 will pull the slider 13 and the blocking block 6 back into the sliding frame 11 under the limit of the slot 1, making way for the return of the polished workpiece.

[0061] When the workpiece reaches the fine grinding station, the drive motor 32 and the hydraulic telescopic rod 30 are started. The drive motor 32 drives the worm 33, worm wheel 46 and rotating shaft 34 to rotate, thereby making the grinding belt 10 rotate at high speed. At the same time, the hydraulic telescopic rod 30 pushes the lifting plate 31, so that the high-speed rotating grinding belt 10 is close to the workpiece and performs fine grinding on the edge and inside of the hole.

[0062] After fine grinding is completed, drive motor 26 rotates in the reverse direction to send the workpiece back to the previous process. During the return process, when the flipping wheel 29 on the clamping frame 9 meshes with the already positioned flipping toothed plate 7, the flipping wheel 29 starts to rotate. This rotation is transmitted through the rotating shaft 1 23, the pulley assembly 1, the rotating shaft 24 and the pulley assembly 2, and finally through the rotating shaft on the clamping frame 9 to drive the clamping frame 9 and its internal working parts to rotate 180°, so that the other unpolished outer surface faces the grinding machine, preparing for the next surface grinding.

[0063] Finally, after all the polishing processes are completed, the drive motor 340 is restarted in reverse. The support plate 8, along with the finished stainless steel drain cover, is reset. During the reset process, when the support plate 8 comes into contact with the moving plate 4, it pushes the moving plate 4. The moving plate 4 pulls the rack 3 towards the blocking block 6 through the hinge 44. This action simultaneously resets the flipping rack 7 and pushes the blocking block 6 back out of the sliding frame 11. At the same time, the fixing block 19 is also locked back into the slot, so that the slider 13 returns to the fixed state, and the entire device returns to the initial ready state.

[0064] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
