Description

Technical Field

[0001] This utility model belongs to the field of sheath pre-tightening technology, specifically a sheath pre-tightening device for a high-speed permanent magnet motor with an adjustable structure. Background Technology

[0002] A high-speed permanent magnet motor is a type of motor that uses permanent magnet materials as the excitation source and generates a rotating magnetic field in the stator windings through current. The protective sleeve for a high-speed permanent magnet motor is a key component used to protect the permanent magnets, preventing damage due to centrifugal force during high-speed rotation. Pre-tightening the protective sleeve is crucial for ensuring the safe and efficient operation of the motor. Its purpose is to apply static preload to the permanent magnets through the sleeve to counteract the tensile stress exerted on the permanent magnets by the centrifugal force generated during high-speed rotation. Existing motor protective sleeve pre-tightening devices require manual removal of the protective sleeve from the bottom of the processing equipment before inserting the next protective sleeve to be processed, resulting in low pre-tightening efficiency. Utility Model Content

[0003] To overcome the above-mentioned defects, this utility model provides a high-speed permanent magnet motor sheath pre-tightening device with an adjustable structure, which solves the problem that existing motor sheath pre-tightening devices require manual removal of the motor sheath from the bottom of the processing equipment before inserting the motor sheath to be processed, resulting in low pre-tightening efficiency of the motor sheath.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a pre-tightening device for a sheath of a high-speed permanent magnet motor with an adjustable structure, comprising a mounting platform, a base fixedly connected to the bottom of the mounting platform, a rotating disk rotatably connected to the top of the mounting platform via a bearing, a connecting disk fixedly connected to the bottom of the rotating disk through the mounting platform, a rotating plate rotatably connected to the bottom of the connecting disk via a bearing, a motor fixedly mounted inside the base, and the output end of the motor fixedly connected to the bottom of the rotating plate, connecting blocks fixedly mounted at one end of the rotating plate and the edge of the bottom of the connecting disk, a connecting spring fixedly connected between the two connecting blocks, and the inner wall of the mounting platform, etc. Multiple mounting plates are fixedly installed at an angle. A damping telescopic rod is fixedly installed on one side of the mounting plate inside the mounting platform. A snap-fit ​​block is fixedly connected to the end of the damping telescopic rod away from the mounting plate. A compression spring is sleeved on the surface of the damping telescopic rod between the mounting plate and the snap-fit ​​block. Multiple snap-fit ​​interfaces are provided on the outer circular surface of the connecting plate, and the snap-fit ​​interfaces correspond to the positions of the snap-fit ​​blocks. Several positioning posts are fixedly installed at equal angles on the top of the rotating disk. A processing seat is sleeved on the surface of every four positioning posts. The motor housing body is sleeved inside the processing seat. Six pre-tightening bolts are threadedly connected to the top of the processing seat, and the pre-tightening bolts are threadedly connected to the motor housing body.

[0005] As a further embodiment of this utility model: an electric telescopic frame is fixedly installed on one side of the top of the mounting platform, an mounting plate is fixedly installed on one side of the top of the electric telescopic frame, and an mounting bracket is fixedly installed on the top of the mounting plate.

[0006] As a further embodiment of this utility model: a second motor is fixedly installed at the bottom of the mounting bracket, and a drive gear is fixedly connected to the bottom of the second motor, and the drive gear is rotatably connected to the mounting plate through a bearing.

[0007] As a further embodiment of this utility model: the top of the mounting plate is rotatably connected to six driven gears at equal angles via bearings, and the six driven gears mesh with the driving gear.

[0008] As a further embodiment of this utility model: the bottom of the driven gear is fixedly connected to a rotating rod through the mounting plate, and the six rotating rods are rotatably connected by a connecting ring through a bearing.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This high-speed permanent magnet motor sheath pre-tightening device with an adjustable structure, by setting a rotating plate, a snap-fit ​​block, and a connecting spring, starts the motor to make the rotating plate rotate at low speed. When the rotating plate rotates to contact the snap-fit ​​block inside the snap-fit ​​interface, the rotating plate pushes the snap-fit ​​block to move away from the snap-fit ​​interface. At the same time, the connecting spring pulls the connecting block to make the connecting plate rotate, so that the snap-fit ​​interface corresponds to the position of another snap-fit ​​block. The compression spring rebounds and pushes the snap-fit ​​block into the snap-fit ​​interface, thereby stopping the connecting plate from rotating. The connecting plate drives the rotating plate to complete a fixed angle rotation, so that the processing seat changes position on the top of the rotating plate. The device can continuously pre-tighten the sheath for the motor.

[0013] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0014] like Figure 1-3 As shown, this utility model provides a technical solution: a pre-tightening device for a sheath of a high-speed permanent magnet motor with an adjustable structure, including a mounting platform 1, a base 2 fixedly connected to the bottom of the mounting platform 1, a rotating disk 3 rotatably connected to the top of the mounting platform 1 via a bearing, a connecting disk 4 fixedly connected to the bottom of the rotating disk 3 through the mounting platform 1, a rotating plate 6 rotatably connected to the bottom of the connecting disk 4 via a bearing, a motor 5 fixedly installed inside the base 2, and the output end of the motor 5 fixedly connected to the bottom of the rotating plate 6, connecting blocks 7 fixedly installed at one end of the rotating plate 6 and the edge of the bottom of the connecting disk 4 respectively, a connecting spring 8 fixedly connected between two connecting blocks 7, and multiple mounting plates 9 fixedly installed at equal angles on the inner wall of the mounting platform 1. With the connecting spring 8, when the rotating plate 6 rotates, the connecting spring 8 is stretched. When the rotating plate 6 pushes the locking block 11 out of the locking interface 13, the connecting spring 8 contracts and pulls the connecting disk 4, so that the locking block 11 is locked into the next locking interface 13, completing the fixed angle rotation.

[0015] A damping telescopic rod 10 is fixedly installed on one side of the mounting plate 9 inside the mounting platform 1. A snap-fit ​​block 11 is fixedly connected to the end of the damping telescopic rod 10 away from the mounting plate 9. A compression spring 12 is sleeved on the surface of the damping telescopic rod 10 between the mounting plate 9 and the snap-fit ​​block 11. The outer circular surface of the connecting plate 4 is provided with multiple snap-fit ​​interfaces 13, and the snap-fit ​​interfaces 13 correspond to the positions of the snap-fit ​​blocks 11. Several positioning posts 26 are fixedly installed at equal angles on the top of the rotating plate 3. A processing seat 14 is sleeved on the surface of every four positioning posts 26. A motor housing body 15 is sleeved inside the processing seat 14. Six pre-tightening bolts 16 are threadedly connected to the top of the processing seat 14, and the pre-tightening bolts 16 are threadedly connected to the motor housing body 15. By providing snap-fit ​​interfaces 13, the snap-fit ​​block 11 is engaged inside the snap-fit ​​interface 13, so that the rotation of the connecting plate 4 stops, thereby making the positions of the processing seat 14 and the six pre-tightening bolts 16 correspond.

[0016] An electric telescopic frame 17 is fixedly installed on one side of the top of the mounting platform 1. An mounting plate 18 is fixedly installed on one side of the top of the electric telescopic frame 17. An mounting bracket 19 is fixedly installed on the top of the mounting plate 18. By using the electric telescopic frame 17, the mounting plate 18 is lowered so that the bolt sleeve 25 is close to the pre-tightening bolt 16 for pre-tightening.

[0017] A second motor 20 is fixedly installed at the bottom of the mounting bracket 19. A drive gear 21 is fixedly connected to the bottom of the second motor 20, and the drive gear 21 is rotatably connected to the mounting plate 18 through a bearing. Six driven gears 22 are rotatably connected at equal angles to the top of the mounting plate 18 through bearings, and the six driven gears 22 mesh with the drive gear 21. With the drive gear 21 and driven gears 22, the rotation of the drive gear 21 drives the driven gears 22 to rotate synchronously, so that the bolt sleeve 25 simultaneously tightens multiple pre-tightening bolts 16, and the multiple pre-tightening bolts 16 on the top of the motor housing body 15 are evenly pre-tightened.

[0018] The driven gear 22 is fixedly connected to the rotating rod 23 through the mounting plate 18 at the bottom. The six rotating rods 23 are rotatably connected by a connecting ring 24 through bearings. The bottom of the rotating rod 23 passes through the connecting ring 24 and is fixedly connected to a bolt sleeve 25. The bolt sleeve 25 corresponds to the position of the pre-tightening bolt 16. With the connecting ring 24, the six rotating rods 23 rotate inside the connecting ring 24, so that the six rotating rods 23 are not prone to deviation when rotating synchronously.

[0019] The working principle of this utility model is as follows: The motor housing 15 is placed inside the machining base 14. The pre-tightening bolt 16 is rotated into the motor housing 15 and the machining base 14. The electric telescopic frame 17 is controlled to lower the mounting plate 18, so that the bolt sleeve 25 covers the surface of the pre-tightening bolt 16. The second motor 20 is started to make the drive gear 21 rotate, which drives the six driven gears 22 to rotate synchronously, so that the rotating rod 23 drives the bolt sleeve 25 to rotate and tighten the pre-tightening bolt 16. The bolt sleeve 25 is pre-tightened evenly. After the machining is completed, the first motor 5 is started to make the rotating plate 6 rotate at the bottom of the connecting plate 4, which pulls the connecting spring 8 to produce deformation. When the rotating plate 6 When the locking block 11 rotates over the surface, the locking block 11 is pushed out of the locking interface 13. At this time, the connecting spring 8 returns to its original position and pulls the connecting block 7 to rotate the connecting disk 4. When the locking interface 13 corresponds to the next locking block 11, the compression spring 12 returns and pushes out the locking block 11 and locks it into the locking interface 13, so that the connecting disk 4 stops rotating and achieves a fixed angle deflection of the connecting disk 4. The connecting disk 4 drives the rotating disk 3 to make the processing seat 14 complete the displacement, so that the equipment can continuously pre-tighten the motor sheath body 15 inside the processing seat 14. At the same time, the motor sheath body 15 that has completed the pre-tightening process is taken out, which improves the working efficiency of the equipment.
