Description

Technical Field

[0001] This utility model relates to the technical field of motor lamination manufacturing equipment, specifically to a motor lamination manufacturing equipment. Background Technology

[0002] During the processing of laminations used in motors, a punching process is required. After punching, burrs may be generated on the surface of the lamination at the edge of the punched hole. These burrs need to be removed and polished, otherwise the quality of the lamination will be affected.

[0003] The Chinese Patent Network discloses a device for deburring motor laminations, publication number CN211992198U. Although the device inserts the motor lamination into the mounting space formed by two slots on the mounting base (i.e., the two ends of the motor lamination are respectively engaged in the two slots, and the punched holes on the motor lamination are located directly below the grinding wheels), and the two sliding seats are driven by a drive mechanism to move relative to each other, allowing the two grinding wheels to simultaneously grind the edges of the punched holes on both sides of the lamination, reducing the labor intensity of workers and improving work efficiency, and significantly improving grinding efficiency because the two grinding wheels grind the burrs on both sides of the lamination simultaneously, the drive mechanism, consisting of a rotating shaft and a lead screw and nut, has a simple structure, low manufacturing cost, and convenient operation. However, the size of the mounting base in this patent is not easily adjustable, resulting in the patent only being suitable for motor laminations of a single size and not for different sizes, which is a significant drawback.

[0004] Therefore, a motor lamination manufacturing equipment is proposed. Utility Model Content

A drive rod 11 is fixedly inserted through the mounting base 9; a connecting sleeve 12 is fixed to one end of the drive rod 11, and a grinding part is connected inside the connecting sleeve 12; a mounting strip 26 is fixed to the front end of the mounting plate 2, and a mounting groove 27 is opened at the front end of the mounting strip 26; a third motor 28 is installed at the right end of the mounting strip 26; the output end of the third motor 28 is connected to a second bidirectional lead screw 29 that passes through the mounting strip 26 and extends into the mounting groove 27 through a coupling; a second lead screw nut 30 is threadedly connected to two different threaded areas of the second bidirectional lead screw 29; a fixing strip 31 is fixed to the outer wall of each of the two second lead screw nuts 30; and a fixing groove is opened at the opposite end of each of the two fixing strips 31.

[0030] Specifically, this invention activates a third motor 28, which drives a second bidirectional lead screw 29. Under the drive of the second bidirectional lead screw 29, two second lead screw nuts 30 move two fixing bars 31 closer together or further apart, thereby adjusting the distance between the two fixing bars 31. Compared with existing technologies, this invention can adjust the distance between the two fixing bars 31, allowing it to fix motor laminations of different sizes and to grind them. It has wider applicability and solves the defects existing in the prior art. Example 2

[0031] Please see Figure 1 , 34. This utility model provides a technical solution: a motor lamination manufacturing equipment, the grinding part includes a connecting block 13 and a grinding disc 14 fixedly connected to each other, the connecting block 13 is sleeved inside the connecting sleeve 12, the outer wall of the connecting sleeve 12 is fixed with a rectangular block 15, the rectangular block 15 has a movable cavity 16 inside, the movable cavity 16 has a movable block 17 movably arranged inside, one side inner wall of the movable cavity 16 has a movable hole 32, the outer wall of the connecting sleeve 12 has a through hole 18, the outer wall of the connecting block 13 has a locking hole 19, the outer wall of the movable block 17 is fixed with a locking post 20 movably arranged inside the movable hole 32, the through hole 18, and the locking hole 19, the other side inner wall of the movable cavity 16 has a threaded hole 21, the threaded hole 21 is threadedly connected with a threaded rod 22, one end of the threaded rod 22 is fixed with a knob 23, the outer wall of the movable block 17 has a movable groove 24, the movable groove 24 has a movable cam 25 movably arranged inside, the movable cam 25 is fixed with the end of the threaded rod 22 away from the knob 23.

[0032] Specifically, first, the knob 23 is used to drive the threaded rod 22 to move within the threaded hole 21. As the threaded rod 22 moves, it causes the movable cam 25 to rotate within the movable groove 24. Simultaneously, the threaded rod 22 drives the movable block 17 to move within the movable cavity 16 of the rectangular block 15. As the movable block 17 moves, it causes the locking pin 20 to move within the movable hole 32, through hole 18, and locking hole 19. Once one end of the locking pin 20 disengages from the locking hole 19, the grinding part can be disassembled. Then, a new grinding part (connecting block 13) is placed inside the connecting sleeve 12. Finally, the knob 23 is used to drive the threaded rod 22 within the threaded hole 21. The threaded rod 22 moves within the hole 21, and when it moves, it drives the movable cam 25 to rotate within the movable groove 24. At the same time, the threaded rod 22 drives the movable block 17 to move within the movable cavity 16 of the rectangular block 15. When the movable block 17 moves, it drives the locking pin 20 to move within the movable hole 32, the through hole 18, and the locking hole 19. When one end of the locking pin 20 is inside the locking hole 19, the new grinding part can be fixed. Therefore, this utility model facilitates the disassembly and replacement of grinding parts. By replacing grinding parts of different specifications, the purpose of grinding motor laminations of different sizes can be achieved, making it widely applicable.

[0033] Working principle:

[0034] First, install the base 1 and mounting plate 2 into the designated positions, and adjust the specifications of the grinding parts according to the size of the motor lamination. During adjustment, first use the knob 23 to drive the threaded rod 22 to move within the threaded hole 21. When the threaded rod 22 moves, it will drive the movable cam 25 to rotate within the movable groove 24. At the same time, the threaded rod 22 will drive the movable block 17 to move within the movable cavity 16 of the rectangular block 15. When the movable block 17 moves, it will drive the locking pin 20 to move within the movable hole 32, through hole 18, and locking hole 19. When one end of the locking pin 20 disengages from the locking hole 19, that is... The grinding part can be disassembled, and a new grinding part (connecting block 13) can be placed inside the connecting sleeve 12. Then, the knob 23 is used to drive the threaded rod 22 to move in the threaded hole 21. When the threaded rod 22 moves, it will drive the movable cam 25 to rotate in the movable groove 24. At the same time, the threaded rod 22 will drive the movable block 17 to move in the movable cavity 16 of the rectangular block 15. When the movable block 17 moves, it will drive the locking pin 20 to move in the movable hole 32, the through hole 18, and the locking hole 19. When one end of the locking pin 20 is inside the locking hole 19, the new grinding part can be fixed.

[0035] Next, place the motor lamination between the two fixing bars 31 and start the third motor 28. The third motor 28 will drive the second double-acting screw 29 to work. Under the drive of the second double-acting screw 29, the two second screw nuts 30 will move closer to each other in the mounting groove 27 of the mounting bar 26. At this time, the two fixing bars 31 will move closer to each other. When the two fixing bars 31 and the two fixing grooves abut against the motor lamination, the motor lamination can be fixed.

[0036] Then start the second motor 10, which uses the drive rod 11 to drive the grinding disc 14 to work;

[0037] Then start the first motor 4 at the bottom of the connecting seat 3. The first motor 4 will drive the first double-acting lead screw 5 to work. Under the drive of the first double-acting lead screw 5, the two first lead screw nuts 6 will move closer to each other on the second double-acting lead screw 29. At this time, the two sets of receiving strips 7, support strips 8, and mounting seat 9 will drive the two grinding discs 14 to move closer to each other. When the two grinding discs 14 come into contact with the motor punch, the motor punch can be ground.
