[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] like Figure 1-10 As shown, a stator torsional power mechanism includes a base plate 1, four end-to-end fixed plates 2 are installed on the upper side of the base plate 1 by bolts, and bearing support plates 3 are installed on the upper side of the four fixed plates 2 by bolts. An outer support assembly 6 located on the inner side of the four fixed plates 2 is arranged in the bearing support plate 3, and the fixed plate 2 is provided with two sets of upper and lower power assemblies 5 for driving the outer support assembly 6 to rotate. A torsional cylinder assembly 4 for twisting the stator end is provided on the upper side of the outer support assembly 6, and the torsional cylinder assembly 4 can rotate synchronously with the outer support assembly 6.

[0026] During use, the staff places the stator to be twisted on the twisting cylinder assembly 4, and inserts the end of the stator into the twisting cylinder assembly 4. Then the staff starts the power assembly 5 to drive the outer support assembly 6 to rotate, and the outer support assembly 6 drives the twisting cylinder assembly 4 to rotate, thereby achieving twisting of the stator end.

[0027] In this embodiment, the outer support assembly 6 includes a first multi-disc bearing 603 installed on the bearing support plate 3 through a bearing and a support cylinder 601 arranged on the lower side of the first multi-disc bearing 603. The first multi-disc bearing 603 includes a first fixed disk 604 installed on the bearing support plate 3 through bolts and a plurality of first bearing disks 605 arranged radially from the outside to the inside along the first fixed disk 604. The outer diameters of the plurality of first bearing disks 605 increase from the inside to the outside. The support cylinder 601 includes a plurality of outer support cylinders 602 stacked from the outside to the inside. The inner diameter of the outer support cylinder 602 decreases from the outside to the inside, and the length increases. The number of outer support cylinders 602 is the same as that of the first bearing disk 605. A plurality of positioning holes 606 are opened through the upper side of the outer support cylinder 602. A plurality of threaded holes matching the positioning holes 606 are opened on the first bearing disk 605. The upper side of the first multi-disc bearing 603 is connected to the torsion cylinder assembly 603 and 605, and the first bearing disk 605 is connected to the outer support cylinder 602 through the threaded hole, so that the outer support cylinder 602 and the first bearing disk 605 are connected one by one during installation. The annular side surface of each outer support cylinder 602 is connected and fixed to one of the power components 5, so that the power component 5 can drive multiple outer support cylinders 602 to rotate, and multiple outer support cylinders 602 rotate independently. When in use, each group of power components 5 drives one of the outer support cylinders 602 to rotate, so that multiple outer support cylinders 602 rotate independently. When the outer support cylinder 602 rotates, it drives the first bearing disk 605 to rotate, so that the first bearing disk 605 drives the torsional cylinder assembly 4 to rotate, thereby realizing the torsion of the copper wire at the stator end.

[0028] In this embodiment, the power assembly 5 includes a support block 501, a fixed block 505, a mounting block 506, a lead screw 502 rotatably connected to the fixed block 505 and the support block 501 on opposite sides through a bearing, and a motor 507 mounted on the mounting block 506 away from the fixed block 505 by a bolt. The support block 501, the fixed block 505, and the mounting block 506 are linearly arranged on the outer side of the fixed plate 2 in sequence by bolts. One end of the lead screw 502 passes through the fixed block 505 and is connected to the output shaft of the motor 507. The lead screw 502 is threadedly connected to the nut slide 504. A rectangular hole corresponding to the lead screw 502 is opened on the fixed plate 2. A linkage assembly 7 is provided at one end of the nut slide 504 through a rectangular groove. The linkage assembly 7 can drive the outer support cylinder 602 to rotate. A sensing part 503 for controlling the movement of the nut slide 504 is provided on the nut slide 504 and the fixed plate 2. The sensing part 503 is electrically connected to the motor 507 through a cable.

[0029] During use, the staff controls the motor 507 to drive the screw 502 to rotate. Under the action of the thread, the nut slide 504 moves along the screw 502 between the two sensing parts 503. When the nut slide 504 moves to one of the sensing parts 503, the sensing part 503 transmits a signal to the motor 507 to make the motor 507 rotate in the opposite direction, thereby realizing the reciprocating movement of the nut slide 504 on the screw 502. When the nut slide 504 moves, the nut slide 504 passes through one end of the rectangular hole and pushes the outer support tube 602 to rotate through the linkage assembly 7, thereby realizing the reciprocating rotation of the outer support tube 602.

[0030] In this embodiment, the sensing part 503 includes two assembly plates 509 installed on the outer surface of the fixed plate 2 by bolts and a sensing piece 508 installed on the side of the nut slide 504 by bolts. A slot-shaped photoelectric 510 is provided on the assembly plate 509. One end of the sensing piece 508 can move into the slot-shaped photoelectric 510 along with the nut slide 504. The slot-shaped photoelectric 510 is electrically connected to the motor 507 through a cable. The two assembly plates 509 are both located between the support block 501 and the fixed block 505. When in use, the sensing piece 508 moves into the slot-shaped photoelectric 510 along with the nut slide 504, triggering the signal of the slot-shaped photoelectric 510, and transmitting the signal to the motor 507 through the cable, causing the motor 507 to rotate in the opposite direction, thereby realizing the control of the moving range of the nut slide 504 and at the same time, realizing the control of the rotation amplitude of the external support cylinder 602.

[0031] In this embodiment, the linkage assembly 7 includes a connecting slide 701 installed by bolts at one end of the rectangular hole extending out of the nut slide 504, a rotating push block 702 installed by bolts on the side of the connecting slide 701 away from the nut slide 504, a follower 703 installed by bolts at the end of the rotating push block 702 away from the connecting slide 701, and a thrust block 705 integrally formed on the annular side of the outer support tube 602. A "U"-shaped following groove 704 is provided at one end of the thrust block 705 close to the follower 703, and the opening of the following groove 704 faces the fixed plate 2. The follower 703 can slide along the following groove 704. When in use, the follower 703 slides along the following groove 704 under the action of the power assembly 5, thereby pushing the thrust block 702 to move, thereby causing the outer support tube 602 to rotate and drive the torsional tube assembly 4 to rotate to twist the stator end.

[0032] In this embodiment, the torsion cylinder assembly 4 includes a second multi-disc bearing 402 mounted on the upper side of the first multi-disc bearing 603 by bolts and a plurality of torsion cylinders 401. The second multi-disc bearing 402 includes a second fixed disk 403 mounted on the upper side of the first fixed disk 604 by bolts and a plurality of second bearing disks 407 arranged in sequence along the radial direction of the second fixed disk 403. The outer diameters of the plurality of second bearing disks 407 increase from the inside to the outside. The plurality of torsion cylinders 401 are stacked together in sequence, and the inner diameters decrease from the outside to the inside. The upper side of the torsion cylinder 401 is provided with a plurality of wire holes 407 in a circular array. 06. Two second protrusions 408 are symmetrically provided on the lower side of the torsion cylinder 401. Two second grooves 405 that cooperate with the second protrusions 408 are symmetrically provided on the upper side of the second bearing disk 407. The number of second bearing disks 407 is the same as that of the torsion cylinder 401, and there is a one-to-one correspondence between the torsion cylinder 401 and the second bearing disks 407. Two first protrusions 404 are symmetrically provided on the lower side of the second bearing disk 407. First grooves 607 that cooperate with the first protrusions 404 are symmetrically provided on the upper side of the first bearing disk 605. The first bearing disk 605 and the second bearing disk 407 correspond one-to-one.

[0033] When in use, the first protrusion 404 is inserted into the first groove 607 so that the first multi-disc bearing 603 and the second multi-disc bearing 402 are engaged with each other, and the second protrusion 408 is inserted into the second groove 405 so that the second multi-disc bearing 402 and the multiple torsion cylinders 401 are engaged with each other. When twisting, the staff inserts the end of the stator copper wire to be twisted into the wire hole 406 of the torsion cylinder 401, and then the power component 5 drives the outer support cylinder 602 to rotate, thereby driving the first multi-disc bearing 603 to rotate. Under the action of the first protrusion 404 and the first groove 607, The first multi-disc bearing 603 drives the second multi-disc bearing 402 to rotate synchronously. Under the action of the second protrusion 408 and the second groove 405, the second multi-disc bearing 402 drives the torsion cylinder 401 to rotate synchronously, thereby achieving the purpose of twisting the copper wire at the end of the stator. The power transmission between the first multi-disc bearing and the second multi-disc bearing 402 reduces the length of the torsional power transmission, and avoids the excessive torque generated by long-distance power transmission and causing internal damage to the equipment mechanism, thereby extending the service life of the equipment to a certain extent, relatively reducing the processing accuracy of each component, and saving production costs.
