[0023] The technical solution of the utility model is further elaborated in detail below in conjunction with the accompanying drawings and specific embodiments of the specification.

[0024] Embodiment 1: The present application provides a micromotor rotor coil shaping device, comprising a base 1; a mounting cavity 101 is provided on the inner side of the base 1, a support plate 2 is fixedly installed on the bottom of the base 1, a rotating mechanism 3 is provided on the inner side of the support plate 2, a placement cavity 4 is provided inside the rotating mechanism 3, and a limiting mechanism 5 is provided at equal intervals on the groove wall of the placement cavity 4;

[0025] The limiting mechanism 5 includes a placement groove 501, an electromagnet 502, a spring 503 and a limiting block 504. The inner wall of the placement groove 501 is fixedly installed with the electromagnet 502, the interior of the placement groove 501 is installed with a spring 503, and the limiting block 504 is slidably installed on one side of the spring 503. The rotating mechanism 3 includes a motor body 301, a hydraulic cylinder 302 and a placement plate 303. The motor body 301 is fixedly installed at the bottom of the support plate 2, the output end of the motor body 301 is fixedly connected to the hydraulic cylinder 302, the top of the hydraulic cylinder 302 is fixedly installed with the placement plate 303, and the placement plate 303 A placement cavity 4 is provided on the inner side, a rotor body 6 is installed inside the placement cavity 4, and fixing grooves 601 are provided on the surface of the rotor body 6 at equal intervals. A shaping mechanism 7 is symmetrically provided on the surface of the base 1, and a support frame 9 is provided on the surface of the base 1. A positioning mechanism 10 is fixedly installed at the bottom of the support frame 9. The positioning mechanism 10 includes an electric push rod 1001, a positioning plate 1002 and a rotating groove 1003. The electric push rod 1001 is fixedly installed below the support frame 9, and a positioning plate 1002 is fixedly installed at the bottom of the electric push rod 1001. A rotating groove 1003 is provided at the central position of the positioning plate 1002;

[0026] Specifically, Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, when winding the rotor body 6, the personnel inserts the rotor body 6 into the placement cavity 4. During the insertion process, the bottom of the rotor body 6 will squeeze the limit block 504, and squeeze the limit block 504 into the placement groove 501. When the limit block 504 corresponds to the fixed groove 601 on the surface of the rotor body 6, the limit block 504 will pop outward under the action of its internal spring 503, and then the limit block 504 can be bounced into the fixed groove 601, so that the rotor body 6 can be fixed in the placement cavity 4, so that the rotor body 6 can be kept stable on the surface of the placement plate 303 to a certain extent. At the same time, the personnel can turn on the electric push rod 1001 through the external controller, and drive the positioning plate 1002 to move downward through the electric push rod 1001, so that the rotor body 6 can be quickly inserted into the rotating groove 1003, and then the upper and lower ends of the rotor body 6 can be limited and fixed. At this time, the motor body 301 is turned on and driven by the motor body 301. The movable placement plate 303 rotates, and the cables inside the rotor body 6 can be quickly wound and arranged. When the device completes winding the rotor body 6, the personnel can energize the electromagnet 502 through the external controller. When the electromagnet 502 is energized, the magnetic force generated will suck the limit block 504 into the placement groove 501, and the limit block 504 will be separated from the fixing groove 601, so that it is convenient for personnel to quickly take out the rotor body 6 from the placement cavity 4. Through the coordinated use of the limit mechanism 5 and the positioning mechanism 10, the rotor body 6 can be quickly fixed and limited, and the deviation and looseness in the process of winding the rotor body 6 can be avoided, thereby improving the working efficiency of the device for winding the rotor body 6 to a certain extent. During the use of the device, through the conductive slip ring set on the motor body 301, the electromagnet 502 and the hydraulic cylinder 302 are electrically connected through the wire, so as to avoid the wire entanglement during the use of the device, thereby further ensuring the normal use of the device.

[0027] Further, the shaping mechanism 7 includes a slide groove 701, an electric slide rail 702 and a shaping plate 703. The slide groove 701 is provided on the surface of the base 1. The electric slide rail 702 is fixedly installed inside the slide groove 701. The shaping plate 703 is slidably installed on the surface of the electric slide rail 702. An elastic mechanism 8 is provided on the inner side of the shaping plate 703. The elastic mechanism 8 includes a second spring 801 and a deformation pad 802. The second spring 801 is installed at equal intervals on the inner side of the shaping plate 703. The deformation pad 802 is slidably installed on one side of the second spring 801.

[0028] Specifically, Figure 1 , Figure 2As shown, after the winding of the rotor body 6 is completed, the personnel can open the electric slide rail 702 through the external controller, and move on the surface of the electric slide rail 702 through the shaping plate 703. Since the shaping plate 703 is an arc-shaped structure, in the process of shaping the wires on the surface of the rotor body 6, the deformation pad 802 inside the shaping plate 703 will be deformed, causing the spring 2 801 to be in a compressed state, so that the deformation pad 802 inside the shaping plate 703 can match the winding shape outside the rotor body 6. Through the setting of the elastic mechanism 8 set on the inner side of the shaping plate 703, the shaping plate 703 can adjust the winding size of the outer side of the rotor body 6, which can not only quickly shape the winding on the surface of the rotor body 6, but also can meet the use of rotor bodies 6 of different sizes and thicknesses, thereby further improving the applicability of the device.

[0029] Working principle: When winding the rotor body 6, the personnel insert the rotor body 6 into the placement cavity 4. During the insertion process, the bottom of the rotor body 6 will squeeze the limit block 504, and squeeze the limit block 504 into the placement groove 501. When the limit block 504 corresponds to the fixed groove 601 on the surface of the rotor body 6, the limit block 504 will pop outward under the action of its internal spring 503, and then the limit block 504 can be bounced into the fixed groove 601, so that the rotor body 6 can be fixed in the placement cavity 4. Thereby, the rotor body 6 can be kept stable on the surface of the placement plate 303 to a certain extent. At the same time, the personnel can turn on the electric push rod 1001 through an external controller, and drive the positioning plate 1002 to move downward through the electric push rod 1001, so that the rotor body 6 can be quickly inserted into the interior of the rotating groove 1003, and then the upper and lower ends of the rotor body 6 can be limited and fixed. At this time, the motor body 301 is turned on, and the placement plate 303 is driven to rotate by the motor body 301, so that the cables inside the rotor body 6 can be quickly wound and arranged.

[0030] Finally, it should be noted that the above specific implementation methods are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model is described in detail with reference to the embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified and replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
