Description

Technical Field

[0001] This utility model relates to the field of grinding technology, and in particular to a grinding device for iron core production. Background Technology

[0002] The stator core is a crucial component of the stator and a major part of the motor's magnetic circuit. It consists of parts such as fan-shaped plates, ventilation slots, positioning ribs, upper and lower toothed pressure plates, tension bolts, and support plates. Chinese utility model patent, authorized publication number "CN218964945U", discloses a stator core grinding device for motor production. This utility model improves upon existing technology, preventing the scattering of debris and dust, and effectively collecting these impurities for convenient later cleaning and maintenance. It also avoids the risk of hot metal debris damaging workers' skin and clothing. Furthermore, this utility model allows for quick and easy replacement of grinding components, enabling faster changes to grinding components for different stator core models, greatly improving practicality.

[0003] When using the above-mentioned technical solution, although the existing device can drive the clamped iron core to rotate and achieve multi-directional grinding of the outer surface, the two sides of the iron core also need to be ground. Currently, after the outer surface of the iron core is ground, additional grinding work is required on the two sides of the iron core. When grinding is required on the sides or other parts of the iron core, the position of the iron core needs to be adjusted manually multiple times, which seriously affects the overall grinding efficiency of the iron core and makes it difficult to meet the needs of high-efficiency production. Therefore, we propose a grinding device for iron core production. Utility Model Content

[0027] Please see Figure 1-5 This utility model provides a technical solution: a grinding device for iron core production, comprising:

[0028] Iron core grinding box 1, with a collection box slidably connected inside the iron core grinding box 1, and two box doors hinged on one side of the iron core grinding box 1;

[0029] The core adjustment structure is located inside the core grinding box 1.

[0030] The core adjustment structure includes two fixed plates 14, a rotating plate 16, a second motor 13, and a rotating disk 21. The two fixed plates 14 are fixedly connected inside the core grinding box 1. The rotating plate 16 is rotatably connected to the opposite surfaces of the two fixed plates 14. The second motor 13 is fixedly installed on the corresponding fixed plate 14. The output end of the second motor 13 rotates through the corresponding fixed plate 14 and is fixedly connected to the rotating plate 16. The rotating disk 21 is rotatably connected inside the rotating plate 16. The top of the rotating disk 21 has three sliding grooves 20. The inside of the rotating disk 21 has a transmission groove 22. The rotating motor 2 is fixedly installed inside the rotating disk 21. The output end of the rotating motor 2 rotates into the inside of the transmission groove 22 and is fixedly connected to the main bevel gear 23.

[0031] The core adjustment structure also includes three secondary bevel gears 24, three second threaded rods 25, and three clamping plates 19. The three second threaded rods 25 are rotatably connected to the interior of the corresponding sliding groove 20. One end of each of the three second threaded rods 25 extends rotatably into the interior of the transmission groove 22 and is fixedly connected to the corresponding secondary bevel gear 24. The three secondary bevel gears 24 are meshed with the main bevel gear 23. The three clamping plates 19 are threaded onto the outer surface of the corresponding second threaded rod 25. The bottom ends of the three clamping plates 19 are slidably connected to the interior of the corresponding sliding groove 20.

[0032] A gear ring 17 is fixedly sleeved on the outer surface of the rotating disk 21, and a third motor 15 is fixedly installed on the outer surface of the rotating plate 16. A gear 18 is fixedly connected to the output end of the third motor 15, and the gear 18 meshes with the gear ring 17.

[0033] Two electric push rods 3 are fixedly installed on the top of the iron core grinding box 1. The telescopic ends of the two electric push rods 3 slide into the interior of the iron core grinding box 1 and are fixedly connected to the lifting frame 6. The lifting frame 6 is rotatably connected to the first threaded rod 8. The first motor 7 is fixedly installed on one side of the lifting frame 6. The output end of the first motor 7 rotatably extends into the interior of the lifting frame 6 and is fixedly connected to the first threaded rod 8. Two limit rods 10 are fixedly connected inside the lifting frame 6. A moving plate 9 is threadedly sleeved on the outer surface of the first threaded rod 8. The moving plate 9 is slidably connected to the outer surfaces of the two limit rods 10. A grinding mechanism 11 is fixedly installed at the bottom of the moving plate 9.

[0034] A dust collection box 5 is fixedly connected to the side of the iron core grinding box 1 away from the box door. An exhaust fan 4 is fixedly installed on the side of the dust collection box 5 away from the iron core grinding box 1. The exhaust end of the exhaust fan 4 is connected to the inside of the dust collection box 5. A sealing cover is provided on the exhaust end of the exhaust fan 4. A dust collection box 12 is fixedly connected to the inside of the iron core grinding box 1. Multiple dust collection ports are opened on one side of the dust collection box 12. The dust collection box 12 is connected to the inside of the dust collection box 5 through a pipe.

[0035] Furthermore, when using this device, the rotating motor 2 is started by connecting an external power source. The rotating motor 2 drives the main bevel gear 23 to rotate. The rotation of the main bevel gear 23 drives the three secondary bevel gears 24 to rotate synchronously. The rotation of the three secondary bevel gears 24 drives the corresponding second threaded rods 25 to rotate. The rotation of the three second threaded rods 25 drives the corresponding clamping plates 19 to move horizontally under the guidance inside the corresponding sliding grooves 20, so that the iron core is placed on the top of the rotating disk 21, which facilitates the three clamping plates 19 to abut against the inner wall of the iron core, thereby facilitating the fixing of the iron core.

[0036] Furthermore, when using this device, by connecting an external power source to start two electric push rods 3 and a first motor 7, the two electric push rods 3 will drive the lifting frame 6 to move downward, thereby facilitating the grinding mechanism 11 to approach the iron core for grinding. The first motor 7 can drive the first threaded rod 8 to rotate. The rotation of the first threaded rod 8 will drive the moving plate 9 to move horizontally under the guidance of the two limit rods 10, thereby facilitating adjustment according to the position of the iron core, so that the grinding mechanism 11 can start to grind the top of the iron core.

[0037] Furthermore, when using this device, after the top of the iron core has been polished, when it is necessary to polish the outer surface of the iron core, the second motor 13 and the third motor 15 are started by connecting an external power source. The second motor 13 can drive the rotating plate 16 to rotate, so that the rotating plate 16 drives the iron core to rotate to a horizontal state. The third motor 15 can drive the gear 18 to rotate, and the rotation of the gear 18 will drive the gear ring 17 to rotate the rotating disk 21, so that the iron core can rotate, thereby facilitating the polishing mechanism 11 to polish the outer surface of the iron core.

[0038] Furthermore, when using this device, after the outer surface of the iron core is polished, it is only necessary to flip and clamp the unpolished bottom of the iron core so that the three clamping plates 19 can clamp the outer surface of the iron core, thereby facilitating the replacement of the polishing disc on the polishing mechanism 11. The replaced polishing disc can then polish the unpolished side and inner wall of the iron core. Since the iron core is produced in batches, the outer surface of the iron core needs to be polished before its inner wall is polished, so that the outer surface, inner wall and both sides of the iron core only need to be positioned and clamped twice.

[0039] With the cooperation of the rotating plate 16, the fixed plate 14, the rotating disk 21, the gear ring 17 and the gear 18, the three clamping plates 19 can clamp and fix the outer surface and inner wall of the iron core respectively, which facilitates the grinding of the outer surface and inner wall of the iron core. When grinding the outer surface and inner wall of the iron core, one side of the iron core can be ground at the same time, thereby reducing the operation steps when grinding other parts of the iron core and further improving the grinding efficiency of the iron core.
