Description

Technical Field

[0001] This invention relates to the field of surface grinding technology, and in particular to a linear air gap surface grinding machine for magnetic materials. Background Technology

[0002] In the production process of magnetic materials, surface grinders are usually used to process the workpieces. The two surfaces of the sintered material need to be ground. When manufacturing magnetic core parts made of a soft magnetic oxide material, the processing steps include grinding both sides and opening the air gap. As a type of grinder, the surface grinder mainly uses a linear motor module to load the workpiece and move it back and forth to cooperate with the rotation of the grinding wheel to grind the workpiece to achieve the required flatness.

[0003] Existing surface grinders for processing magnetic materials mostly use clamps to fix the workpiece on the processing table surface. After grinding one surface, the clamps are powered off, and the workpiece is then manually flipped over to grind the other side. However, in the case of high-speed continuous operation of the grinding machine, the workload of the operator is significantly increased, making it easy to feel fatigued during long-term repetitive processing, and also posing safety hazards to production. Therefore, this application provides a linear through-type air gap surface grinder for magnetic materials to meet the requirements. Summary of the Invention

[0015] In summary, the technical effects and advantages of this invention are as follows:

[0016] 1. This invention has a reasonable structure. By setting a fixing mechanism, the third motor operates to drive the bidirectional threaded rod to rotate, driving two sets of clamping plates to approach each other and contact the outer wall of the workpiece to clamp and fix the workpiece, so as to facilitate grinding operations. After the grinding operation on the upper surface of the workpiece is completed, the second motor operates to drive the grinding wheel to move upward, and simultaneously drives two sets of second cylinders to operate to push the two sets of connecting blocks to move upward. The movement of the connecting blocks drives the connecting frame to move upward as a whole. The movement of the connecting frame drives the connecting shaft and the workpiece fixed by the two sets of clamping plates to move upward as a whole. During the continuous movement of the connecting shaft, the plane of the toothed ring on the outer wall of the connecting shaft gradually contacts the clamping block. Under the action of the clamping block, the toothed ring rotates. The rotation of the toothed ring drives the clamping plate to rotate. The rotation of the clamping plate drives the workpiece to flip over, avoiding the need for manual workpiece flipping, significantly reducing the workload of workers, reducing the number of operation steps where workers directly contact the processing equipment and workpiece, thereby reducing and avoiding safety hazards.

[0017] 2. By setting up an auxiliary mechanism, this invention increases the reciprocating distance of the linear motor module-driven slider when processing large workpieces. Simultaneously, the reciprocating movement of the two sets of sliders drives the processing table to reciprocate for workpiece grinding. The increased movement distance of one set of sliders causes the protrusions on its outer wall to contact the nozzles. During the continuous operation of the linear motor module, the two sets of protrusions, through the arched structure on their outer surfaces, push the two sets of nozzles to reciprocate around the connecting plate. The oscillation of the two sets of nozzles causes the connecting plate to rotate reciprocally. This rotation, via a push rod, drives the mounting sleeve and the nozzles inside the mounting sleeve to reciprocate, thereby increasing the spray area of ​​the nozzles. This improves the cooling and cleaning effect on the workpiece surface, preventing high temperatures and debris from affecting the workpiece's processing yield and thus saving production costs.

[0029] Example: Reference Figure 1-8The illustrated magnetic material linear through-type air gap surface grinder includes a worktable 1 and a linear motor module 2 fixedly mounted on one side of the top of the worktable 1. Two sets of slide rails 201 are symmetrically fixedly mounted on the top of the linear motor module 2, and two sets of sliders 202 are movably disposed on the top of the two sets of slide rails 201. A second connecting component 11 extending into the interior of the linear motor module 2 is fixedly connected to the other side of the top of the worktable 1.

[0030] like Figures 1-8As shown, the fixing mechanism includes a clamping assembly and a flipping assembly. The clamping assembly includes a processing table 12 fixedly connected to the top of the two sets of sliders 202. The top of the processing table 12 is provided with a connecting frame 19 extending to both sides of the outer wall of the processing table 12. A third motor 15 is fixedly connected to one end of the connecting frame 19. A bidirectional threaded rod 17 is rotatably connected to the inside of one side of the connecting frame 19. A limit rod 20 is fixedly connected to the other side of the connecting frame 19. Mounting plates 22 are provided at both ends of the inner wall of the connecting frame 19. Clamping plates 16 are provided at the ends of the two sets of mounting plates 22 that are close to each other. The third motor 15 is electrically connected to the PLC controller through wires. The flipping assembly includes two sets of mounting rods 21 that are threadedly connected to both sides of the processing table 12 and extend to the top of the processing table 12. Multiple sets of movable grooves extending to the outer surface of the mounting rod 21 are equally spaced inside the mounting rod 21. Each set of movable grooves contains a locking block 32 extending to the outside of the mounting rod 21. A telescopic spring 33 is fixedly connected inside each set of movable grooves, with the other end of the telescopic spring 33 fixedly connected to the locking block 32. Two sets of second cylinders 13 are fixedly connected to the worktable 1 on both sides of the outer wall of the linear motor module 2. The output ends of both sets of second cylinders 13 are fixedly connected to connecting blocks 14 that are slidably connected to the lower end of the connecting frame 19. Connecting shafts 31 are rotatably connected to the interior of both ends of the connecting frame 19. Gear rings 18 are fixedly connected to the outer walls of the ends of the two sets of connecting shafts 31 that are far apart from each other. Through connecting shafts are fixedly connected to the ends of the two sets of clamping plates 16 that are far apart from each other. The rectangular rod 31 has a rectangular groove inside the connecting shaft 31 that matches the rectangular rod. The connecting shaft 31 is slidably sleeved with the rectangular rod through the rectangular groove. The outer wall of the connecting shaft 31 is provided with a protective pad. The two sets of mounting plates 22 are respectively provided with internal threads that match the outer wall of the bidirectional threaded rod 17. The two sets of mounting plates 22 are sleeved on the outer wall of the bidirectional threaded rod 17 through the internal threads. The other end of the two sets of mounting plates 22 is also provided with a through hole that matches the limit rod 20. The mounting plate 22 is slidably connected to the limit rod 20 through the through hole. Before processing the workpiece, the workpiece is placed on the top of the processing table 12. Then, the third motor 15 is operated by the PLC controller. The operation of the third motor 15 drives the bidirectional threaded rod 17 to rotate. The rotation of the grinding rod 17 drives the two sets of mounting plates 22 to move closer to each other. This movement of the mounting plates 22 pushes the two sets of clamping plates 16 closer together, contacting the outer wall of the workpiece. Each side of the clamping plates 16 that is close to each other is equipped with a rough-surface friction pad. The rough-surface friction pad improves the clamping stability of the workpiece, facilitating grinding operations. The outer wall teeth of the toothed ring 18 are designed with a semi-circular structure. The two sets of second cylinders 13 are electrically connected to the PLC controller via wires. After the grinding operation on the upper surface of the workpiece is completed, the second motor 7 drives the grinding wheel 10 to move upwards, simultaneously driving the two sets of second cylinders 13 to push the two sets of connecting blocks 14 upwards. The movement of the connecting blocks 14 causes the connecting frame 19 to move upwards as a whole.The movement of the connecting frame 19 drives the connecting shaft 31 and the workpiece fixed by the two sets of clamping plates 16 to move upwards. During the continuous movement of the connecting shaft 31, the plane of the teeth on the outer wall of the gear ring 18 gradually contacts the clamping block 32. Under the action of the clamping block 32, the gear ring 18 rotates. The rotation of the gear ring 18 drives the clamping plates 16 to rotate, causing the workpiece to flip. Then, when the second cylinder 13 is driven to move in the opposite direction, the arc-shaped surface of the teeth on the outer wall of the gear ring 18 contacts the clamping block 32. At this time, the clamping block 32 will retract into the moving groove under the push of the arc-shaped surface, preventing the gear ring 18 from rotating and deflecting. Through the cooperation of the above parts, the workpiece flipping operation can be completed, thus avoiding the need for manual workpiece flipping, significantly reducing the workload of workers, and reducing the number of steps where workers directly contact the processing equipment and workpiece, thereby reducing and avoiding safety hazards.

[0031] like Figures 1-8As shown, the auxiliary mechanism includes a cooling sprayer 35 fixedly connected to the outer wall of the protective cover 34 near the first cylinder 9. A universal sleeve 27 is fixedly connected to the output end of the cooling sprayer 35, and a nozzle 26 is fixedly connected to the output end of the universal sleeve 27. An mounting sleeve 28 is fitted onto the outer wall of the nozzle 26. The auxiliary mechanism also includes a fixed base plate 23 fixedly connected to the outer wall of the linear motor module 2 near the U-shaped frame 6. A connecting plate 24 is fixedly connected to the top of the fixed base plate 23 on the side away from the linear motor module 2. Two sets of nozzles 26 are fixedly connected to the top and bottom ends respectively. A set of sliders 202 is fixedly connected to a fixing block 29 near the outer wall of the connecting plate 24. Two sets of protrusions 30 are fixedly connected to the top and bottom ends of the fixing block 29 respectively. A top rod 25 fixedly connected to the mounting sleeve 28 is fixedly connected to the top of the connecting plate 24. The two sets of protrusions 30 are both set with an arched structure near the connecting plate 24. When processing a large workpiece, the distance of the reciprocating movement of the sliders 202 driven by the linear motor module 2 will also increase. At this time, the reciprocating movement of the two sets of sliders 202 drives the processing table 12 to reciprocate to perform the workpiece grinding operation. At the same time, the increase in the movement distance of one set of sliders 202 will cause the protrusions 30 on its outer wall to contact the nozzles 26. During the continuous operation of the linear motor module 2, the two sets of protrusions 30 push the two sets of nozzles 26 to reciprocate around the connecting plate 24 through the arched structure of the outer surface. The oscillation of the two sets of nozzles 26 drives the connecting plate 24 to rotate itself. The reciprocating rotation of the disc 24 drives the mounting sleeve 28 and the nozzle 26 inside the mounting sleeve 28 to reciprocate through the push rod 25, thereby increasing the spraying area of ​​the nozzle 26 and improving the cooling and cleaning effect on the workpiece surface. This prevents the workpiece surface from being affected by high temperature and debris, thus saving production costs. The bottom of the protective cover 34 is welded and fixed with a partition between the universal sleeve 27 and the grinding wheel 10, which can prevent the universal sleeve 27 from swinging and contacting the grinding wheel 10 during the operation of the equipment.

[0032] like Figures 1-8A cooling sprayer 35 is fixedly connected to the outer wall of the protective cover 34 near the first cylinder 9. A mounting bracket 37 is fixedly connected to the outer wall of the protective cover 34 away from the cooling sprayer 35. A fourth motor 36 is fixedly connected to the top of the mounting bracket 37. A drill bit 4 is provided at the bottom of the mounting bracket 37. A connector extending into the interior of the mounting bracket 37 is fixedly connected to the top of the drill bit 4 and is rotatably connected to the mounting bracket 37. A transmission assembly is provided inside the mounting bracket 37. The transmission assembly includes a drive gear fixedly connected to the output end of the fourth motor 36 and a driven gear fixedly connected to the other end of the connector. A synchronous belt is sleeved on the outer wall of the drive gear and the driven gear. The fourth motor 36 and the first cylinder 9 are electrically connected to the PLC controller through wires. The connector can be specifically set as a self-locking chuck. After the workpiece clamping operation is completed, the second motor 7 drives the first cylinder 9 and the protective cover 34 to move downward as a whole. Through the gap between the grinding wheel 10 and the drill bit 4, the grinding wheel 10 and the drill bit 4 are moved downward. The processing table 12 is misaligned. When the protective cover 34 continues to move downward, it can drive the mounting bracket 37 and the drill bit 4 to move downward, so that the drill bit 4 contacts the workpiece. At the same time, the fourth motor 36 is operated to operate the transmission assembly, causing the drive gear to rotate. The rotation of the drive gear drives the synchronous belt to rotate, and the rotation of the synchronous belt drives the driven gear to rotate. The rotation of the driven gear drives the connecting piece to rotate, and the rotation of the connecting piece drives the drill bit 4 to rotate, thus completing the drilling and air gap opening operation on the workpiece. Then, when operating in the reverse direction, the second motor 7 drives the protective cover 34, the mounting bracket 37 and the second motor 7 to move upward as a whole to separate them. The operation of the first cylinder 9 pushes the protective cover 34 and the grinding wheel 10 to move laterally, so that the grinding wheel 10 is above the workpiece for grinding. Through the cooperation of the above-mentioned multiple parts, the drilling and grinding operations on the workpiece can be realized, reducing the subsequent processing steps on the workpiece, thereby further saving production costs.

[0033] Working principle of this invention:

[0034] Before processing, the workpiece is placed on top of the processing table 12 by setting a fixing mechanism. Then, the third motor 15 is operated by the PLC controller. The operation of the third motor 15 drives the bidirectional threaded rod 17 to rotate. The rotation of the bidirectional threaded rod 17 drives the two sets of mounting plates 22 to move closer to each other. The movement of the two sets of mounting plates 22 pushes the two sets of clamping plates 16 closer to each other and into contact with the outer wall of the workpiece. The rough friction pad is set to improve the clamping stability of the workpiece, so as to facilitate the grinding operation. The teeth on the outer wall of the toothed ring 18 are set with a semi-circular structure. The two sets of second cylinders 13 are electrically connected to the PLC controller through wires. After the grinding operation on the upper surface of the workpiece is completed, the second motor 7 drives the grinding wheel 10 to move upward. Simultaneously drive the two sets of second cylinders 13 to operate, thereby pushing the two sets of connecting blocks 14 upward, through the connecting blocks 14 The movement of the connecting frame 19 causes the entire connecting frame 19 to move upward, and the movement of the connecting frame 19 causes the connecting shaft 31 and the shaft fixed by the two sets of clamps 16 to move upward. As the workpiece moves upward as a whole, and the connecting shaft 31 continues to move, the connecting shaft 31 drives the flat surface of the toothed ring 18 to engage with the toothed outer wall. The surface gradually comes into contact with the locking block 32. Under the action of the locking block 32, the gear ring 18 rotates, and the rotation of the gear ring 18 drives the clamping plate 16 to rotate. move The workpiece is flipped by the rotation of the clamping plate 16. Then, the second cylinder 13 is driven to move the connecting frame 19 and the workpiece in the opposite direction. When the arc-shaped surface of the toothed ring 18 contacts the locking block 32, the locking block 32 will retract into the moving slide under the push of the arc-shaped surface, preventing the toothed ring 18 from rotating and deflecting. Through the cooperation between the above parts, the flipping operation of the workpiece can be completed, thereby avoiding the need for manual flipping of the workpiece, significantly reducing the workload of the workers, reducing the number of operation steps where workers and processing equipment and workpieces come into direct contact, and thus reducing and avoiding safety hazards.

[0035] By setting up an auxiliary mechanism, when processing larger workpieces, the linear motor module 2 drives the slider 202 to reciprocate a greater distance. At this time, the reciprocating movement of the two sets of sliders 202 drives the processing table 12 to reciprocate for workpiece grinding. Simultaneously, the increased movement distance of one set of sliders 202 causes the protrusions 30 on its outer wall to contact the nozzles 26. During the continuous operation of the linear motor module 2, the two sets of protrusions 30, through the arched structure on their outer surfaces, respectively push the two sets of nozzles 26 to reciprocate around the connecting plate 24. Through the two sets of nozzles... The swing of 26 drives the connecting plate 24 to rotate back and forth. The reciprocating rotation of the connecting plate 24 drives the mounting sleeve 28 and the nozzle 26 inside the mounting sleeve 28 to swing back and forth through the push rod 25, thereby increasing the spraying area of ​​the nozzle 26, thereby improving the cooling and cleaning effect on the workpiece surface, and preventing the workpiece surface from being affected by high temperature and debris, thus saving production costs. The bottom of the protective cover 34 is welded and fixed with a partition between the universal sleeve 27 and the grinding wheel 10, which can prevent the universal sleeve 27 from swinging and contacting the grinding wheel 10 during the operation of the equipment.
