[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0022] Depend on Figures 1 to 4This invention discloses a snap-fit ​​motor rotor silicon steel sheet constraint structure with preload monitoring, comprising a support frame 1, a combined constraint mechanism 2 inside the support frame 1, and a controller 3 fixedly installed at the middle position on one side of the support frame 1. The combined constraint mechanism 2 consists of a silicon steel sheet support and positioning assembly 4 and a silicon steel sheet preload assembly 5. The silicon steel sheet support and positioning assembly 4 is fixedly installed at the bottom end inside the support frame 1, and the silicon steel sheet preload assembly 5 passes through the top end of the support frame 1 and is fixedly connected to the support frame 1. The silicon steel sheet preload assembly 5 is located directly above the silicon steel sheet support and positioning assembly 4. The silicon steel sheet support and positioning assembly 4 consists of a support base plate 6, two hydraulic rods 7, a lifting support platform 8, a center hole positioning rod 9, and several side slot positioning rods 10. The two hydraulic rods 7 are respectively fixedly connected to the two sides of the top end of the support base plate 6, and the lifting support platform 8 is fixedly connected to the two sides of the support base plate 6. The top of each hydraulic rod 7, the center hole positioning rod 9 and the side groove positioning rod 10 are all fixedly connected to the middle position of the top of the support base plate 6. The center hole positioning rod 9 and the side groove positioning rod 10 are slidably inserted into the lifting support platform 8. The silicon steel sheet pre-tightening assembly 5 consists of two hydraulic rods 11, a hanging plate 12, a pressure plate 13, several pressure sensors 14 and a pressure plate 15. The hydraulic rods 11 pass through the support frame 1 and are fixedly connected to the support frame 1. The hanging plate 12 is fixedly connected to the bottom end of the two hydraulic rods 11. The pressure plate 13 is fixedly connected to the middle position of the bottom end of the hanging plate 12. The pressure sensor 14 is fixedly connected to the bottom end of the pressure plate 13. The pressure plate 15 is fixedly connected to the bottom end of the pressure sensor 14. The hanging plate 12, the pressure plate 13 and the pressure plate 15 are all slidably sleeved on the center hole positioning rod 9 and the side groove positioning rod 10. The pressure sensor 14 is a circular array arrangement structure.

[0023] In use, hydraulic rod 11 moves the lifting plate 12, pressure plate 13, pressure sensor 14, and pressure plate 15 upwards as a whole, causing pressure plate 15 to separate from the center hole positioning rod 9 and the side groove positioning rod 10. The silicon steel sheet is then fitted onto the center hole positioning rod 9 and the side groove positioning rod 10. The center hole positioning rod 9 is inserted into the center hole of the silicon steel sheet, and the side groove positioning rod 10 positions the side groove of the silicon steel sheet, ensuring precise alignment of each silicon steel sheet and preventing misalignment. One silicon steel sheet is stacked at a time, and then hydraulic rod 11 moves the lifting plate 12, pressure plate 13, pressure sensor 14, and pressure plate 15 upwards. The entire assembly moves downward, causing the pressure plate 15 to contact and apply pressure to the top silicon steel sheet, thus creating a snap-fit. At this time, pressure sensor 14 monitors pressure at multiple locations. If the pressure of one of the pressure sensors 14 is too high, it indicates that the silicon steel sheet at that location is not fully snapped in place. This can then be checked by the staff. Once the silicon steel sheet is fully assembled to form the rotor, the hydraulic rod 7 drives the lifting support platform 8 to move upward. The lifting support platform 8 then drives the assembled rotor upward, separating the rotor from the center hole positioning rod 9 and the side groove positioning rod 10, making it easier for the staff to remove it.

[0024] The middle positions of the lifting support platform 8, the hanging plate 12, the pressure plate 13 and the pressure plate 2 are all provided with a central hole 16 that matches the central hole positioning rod 9 and several side holes 17 that match the side groove positioning rod 10. They can match the central hole positioning rod 9 and the side groove positioning rod 10 to form a limiting function.

[0025] The support frame 1 has several bolt mounting holes 18 at its bottom, which can be used to fix the support frame 1 in place with bolts. The support base plate 6 is fixedly connected to the support frame 1 with several bolts 19, which can improve the stability of the installation.

[0026] An alarm 20 is fixedly installed on the top of the controller 3, and a display screen 21 is installed on the top of the front of the controller 3. The display screen 21 can display the pressure during pre-tightening, and the alarm 20 can sound an alarm when the pressure is abnormal.

[0027] During operation, a silicon steel sheet support and positioning assembly consisting of a support base plate, two hydraulic rods (first type), a lifting support platform, a center hole positioning rod, and several side groove positioning rods can be used to limit the movement of the silicon steel sheets, improving the accuracy of the silicon steel sheet connection and preventing misalignment. A silicon steel sheet pre-tightening assembly consisting of two hydraulic rods (second type), a hanging plate, a pressure plate (first type), several pressure sensors, and a pressure plate (second type), along with a controller, can individually tighten the silicon steel sheets and monitor the tightening force, ensuring the silicon steel sheets are properly engaged and improving assembly stability. Center holes and side holes on the lifting support platform, hanging plate, pressure plate (first type), and pressure plate (second type) provide limiting functions with the center hole positioning rod and side groove positioning rods. An alarm and display screen can display the pre-tightening pressure in real time, and an alarm can be triggered when the pre-tightening force is abnormal.
