In this embodiment, the first sliding grooves 321 are both arc-shaped, and two end portions of the first sliding grooves 321 are located in different circumferences, an end portion of the first sliding groove 321 close to the accommodating cavity 21 is referred to as a first end portion 3211, and an end portion of the first sliding groove 321 away from the accommodating cavity 21 is referred to as a second end portion 3212. When the first sliding block 311 is close to the first end portion 3211, all the pressing blocks are close to each other to lock the stator 7; when the first slider 311 approaches the second end 3212, all the pressing pieces are away from each other, and at this time, the stator 7 is in an unlocked state. Therefore, when the first slider 311 is fitted in the first slide groove 321 to move, all the pressure plates 31 can be driven to synchronously move closer to or away from the accommodating chamber 21. In this embodiment, when the first rotating disk 32 rotates counterclockwise, the first slider 311 moves from the first end portion 3211 to the second end portion 3212, and the entire pressing plate 31 gradually moves away from the stator 7, so as to unlock the stator 7 from the pressing plate 31. Similarly, when the first rotating disk 32 rotates clockwise, the first slider 311 moves from the second end portion 3212 to the first end portion 3211, and all the pressing plates 31 gradually approach and abut against the stator 7, so as to lock the stator 7.

Similarly, when the second rotary disk 42 rotates clockwise, the second sliding block 412 moves from the fourth end 4212 to the third end 4211, and all the protection blocks 41 gradually approach the stator 7, so that the protection teeth 411 can be embedded in the clamping grooves of the stator 7. As shown in fig. 3 and 4, the clockwise and counterclockwise rotation of the second turntable 42 is based on the position of the second turntable 42 in fig. 3, since the positions of the first turntable 32 and the second turntable 42 in fig. 4 are reversed with respect to fig. 3.

In another embodiment, the second driving member may also be a driving member of an air cylinder or a linear motor, and the protection blocks 41 can be synchronously pushed to approach or separate from the stator 7 by the synchronous movement of multiple groups of driving members, so as to realize the clamping and releasing of the protection teeth 411 to the stator 7.

In this embodiment, the first rotary disk 32 and the second rotary disk 42 are connected through the linkage block, and the central axis of the first rotary disk 32 coincides with the central axis of the second rotary disk 42, so that the first rotary disk 32 and the second rotary disk 42 can rotate synchronously, and the rotating speed of the first rotary disk 32 is equal to that of the second rotary disk 42, thereby facilitating the control of the movement of the pressure plate 31 and the protection block 41. In order to facilitate driving the first and second turntables 32 and 42 to rotate, the motor is connected to the linkage block through a link, so that the torque of the motor can be transmitted to the first and second turntables 32 and 42 by the link.

The fixed mold 2 is provided with a first sensor 22, and the first sensor 22 is used for detecting whether the stator 7 is placed in the accommodating cavity 21, in this embodiment, the first sensor 22 may be a photoelectric sensor, but other types of sensors may also be used.

The shaping device comprises an upper die assembly and a lower die assembly, and the embracing device can move between the upper die assembly and the lower die assembly along a straight line to further shape the coil. The primary shaping process of the stator 7 and the coil by using the pressing plate 31 can be completed before the cohesion device moves to the upper die assembly and the lower die assembly, can be completed in the moving process, and can also be completed after the movement.

The upper die assembly and the lower die assembly both comprise a shaping assembly, the shaping assembly comprises a seat body 5, a third driving piece 51, a push rod 52, a pressing piece 54, a resetting piece 531 and at least two push plates 53, wherein the two seat bodies 5 are respectively arranged on the upper die assembly and the lower die assembly. One of the seat bodies 5 is mounted on the upper module, and the other seat body 5 can be mounted on the module, although the other seat body 5 can also be mounted below the fixed module 2. In the embodiment, the base body 5 is arranged below the fixed die 2, and when the embracing device moves between the upper die assembly and the lower die assembly, the base body 5 arranged below the fixed die 2 and the base body 5 arranged on the upper die assembly are symmetrically arranged. At the moment, the two shaping components are respectively positioned at the upper side and the lower side of the stator 7, so that the coil of the stator 7 can be further shaped and processed by utilizing the matching of the two shaping components and the cohesion device.

The third driving member 51 is fixedly disposed on the seat body 5, and a driving shaft of the third driving member 51 is fixedly connected with the push rod 52, in this embodiment, the third driving member 51 is preferably an air cylinder. All push plates 53 all encircle the circumference setting of push rod 52 to all push plates 53 all are located same circumference, and for make push plates 53 can laminate with stator 7 and coil, push plates 53 all are the arc setting in this embodiment.

The push rod 52 comprises a push section 521 and a contraction section 522, wherein the cross-sectional area of the push section 521 is larger than that of the contraction section 522, i.e. the orthographic projection of the contraction section 522 is located inside the orthographic projection of the push section 521. In the initial state, the contracting section 522 is attached to the push plate 53 or is spaced from the push plate 53 by a certain distance, at this time, the push plates 53 are close to or attached to each other, and the outer wall of the push plate 53 is spaced from the inner wall of the stator 7 by a certain distance, so that the push plate 53 can be inserted into the stator 7. The push rod 52 is then pushed by the third driving element 51 to move axially, so that the pushing section 521 is in contact with the push plate 53, and thus the push plate 53 is pushed to move radially by the radial dimension difference between the contracting section 522 and the pushing section 521, at which time the push plates 53 move away from each other and gradually approach the inner wall of the stator 7 until abutting against the inner side wall of the stator 7. At this time, the pressing plate 31 is pressed on the outside of the stator 7, and the push plate 53 is inserted into the stator 7, so that the coil between the pressing plate 31 and the push plate 53 is pressed by the force of the pressing plate 31 and the push plate 53, thereby shaping the coil.

The pressing member 54 is connected to the push rod 52 and is located at an upper end portion of the push rod 52. When the contracting section 522 is matched with the push plate 53, the pressing part 54 is away from the coil by a certain distance; and when the push plate 53 is engaged when the push rod 52 is moved downward so that the push section 521 is engaged with the push plate 53, the pressing member 54 moves in the axial direction of the push rod 52 and is finally pressed against the upper end of the coil. Since the coil is pressed by the push plate 53 and the pressing plate 31, the coil is elongated in the radial direction of the stator 7, and the coil is pressed by the pressing member 54 in the radial direction of the stator 7, so that the shaping effect can be improved.

All the push plates 53 are connected by the restoring member 531 to assist the restoration of the push plates 53 by the restoring member 531, and the restoring member 531 is preferably an elastic ring in this embodiment. The reset piece 531 is arranged on the push plate 53, when the pushing section 521 applies pushing force to the push plate 53, the push plate 53 is far away along the radial direction of the push rod 52, and at this time, the reset piece 531 is elastically deformed; when the shaping is finished and the push rod 52 retracts in the radial direction, the contraction section 522 is matched with the push plate 53, the thrust exerted on the push plate 53 by the push rod 52 is gradually reduced until the thrust disappears, and meanwhile, the reset piece 531 can convert the self elastic force into the thrust for pushing the push plate 53 to move, so that the push plate 53 is assisted to move towards the center of the push rod 52.

The pressing member 54 is connected to the base through the elastic member 541, so that the pressing member 54 can be restored by the elastic member 541.

The free end of the push rod 52 can penetrate through the positioning plate 55, and the pressing member 54 is also fixedly disposed on the positioning plate 55. After the push plate 53 is inserted into the stator 7, the push rod 52 is pushed by the third driving member 51 until the pressing member 54 contacts the upper end of the coil. Then, the third driving member 51 continues to drive the push rod 52 to move, and at this time, the elastic member 541 located between the positioning plate 55 and the seat 5 is continuously compressed, so that the pressing member 54 applies pressure to the coil under the pressure of the positioning plate 55, and the coil is pressed by the pressing member 54, thereby completing the shaping of the coil. After the shaping is finished, when the pushing force applied to the positioning plate 55 disappears, the elastic member 541 can convert its own elastic force into a pushing force, thereby assisting the pressing member 54 to return.

The upper die assembly and the lower die assembly are connected with a fourth driving part 6, the fourth driving part 6 can drive the upper die assembly and the lower die assembly to move oppositely, and a screw rod is preferred as the fourth driving part 6 in the embodiment.
