It should be noted that, in the process of winding the core wire onto the motor stator, after the core wire is wound to a certain number of turns, the driving piece 51 drives the clamping mechanism 52 to descend, so that the clamping mechanism 52 contacts with the core wire wound onto the motor stator, the core wire is pushed by the clamping mechanism 52 to move continuously along the winding direction of the core wire, so as to improve the tightness of winding the core wire onto the motor stator, and each core wire wound onto the motor stator with different numbers of turns can be driven to move synchronously along the winding direction by the pushing of the clamping mechanism 52, so that the integral tightness is adjusted, rather than the tightness is adjusted by dragging the end part of the core wire, and the core wire wound onto the motor stator is ensured to be stressed relatively uniformly.
As shown in fig. 1-5 and 8, the clamping mechanism 52 comprises a position control mechanism 525, at least one clamping block 521, a plurality of spacing bars 522 and an anti-slip member 523, wherein the at least one clamping block 521 is connected with the output end of the driving member 51, the spacing bars 522 are arranged on the clamping block 521 at intervals, the distance between every two adjacent spacing bars 522 is equal to the distance between every two adjacent core wires wound on the motor stator, the anti-slip member 523 is arranged between every two adjacent spacing bars 522, the position control mechanism 525 is used for adjusting the distance between the clamping block 521 and the core wire wound on the motor stator on the radial section of the motor stator, the spacing bars 522 comprise mounting bars, deformation parts and first compression springs, the mounting bars are inserted into the clamping block 521, the first compression springs are arranged between the mounting bars and the clamping block 521, the deformation parts are connected with the mounting bars, when the deformation parts are extruded by the core wires, the deformation parts and the mounting bars can be pushed to move towards the clamping block 521, and when the deformation parts are separated from the core wires, the mounting bars are used for driving the mounting bars to reset automatically.
When the tightness of the core wire needs to be adjusted, the clamping block 521 is pushed to approach the core wire wound on the motor stator by the position control mechanism 525, so that the clamping mechanism 52 moves to the adjacent position of each circle of core wire, the spacer 522 can push the core wire to be regularly arranged, and the core wire can be accurately aligned with the anti-skid member 523;
At this time, the driving element 51 drives the clamping mechanism 52 to descend, so that the spacer 522 and the anti-slip element 523 move downwards, and the core wire is pulled by the friction force between the spacer 522 and the anti-slip element 523 and the core wire, so that the core wire continues to move along the winding direction of the core wire, thereby achieving the purpose of improving the tightness of the core wire wound on the motor stator, namely, the plurality of anti-slip elements 523 and 523 are arranged, so that the spacer 522 and the anti-slip element 523 can apply a pulling force to the core wire wound on each circle of the motor stator, the stress of the core wire is uniform, and the tightening effect of the core wire is ensured.
As shown in fig. 7-8 and 10, the anti-slip member 523 includes a plurality of sets of anti-slip wheels 5231 and torsion springs 5232, wherein the plurality of sets of anti-slip wheels 5231 are rotatably connected to the clamping block 521, one end of the torsion springs 5232 is disposed at an end of the clamping block 521, and the other end of the torsion springs 5232 is connected to the clamping block 521.
It should be noted that, in order to prevent the grip block 521 from excessively pulling the core wire, the tightening force of the core wire is excessively large, and as the friction force applied to the anti-slip wheel 5231 is increased, the torsion spring 5232 is compressed, and the anti-slip wheel 5231 is allowed to rotate to a certain extent, so that the grip block 521 can be continuously lowered.
As shown in fig. 10, a stopper 5233 is disposed at an end of the torsion spring 5232 away from the anti-slip wheel 5231, a plurality of limiting grooves 5234 are disposed on the clamping block 521 (as shown in fig. 7) at intervals along the circumference, and the center of a circle formed by the plurality of limiting grooves 5234 coincides with the axis of the stopper 5233, and the stopper 5233 is inserted into one of the limiting grooves 5234.
It should be noted that, to further prevent the force of pulling the core wire from being too large, when the torsion spring 5232 is stressed too large, the limiting block 5233 is separated from one of the limiting grooves 5234, and at this time, the compressed torsion spring 5232 is twisted to a certain extent, and the elasticity is reduced until the limiting block 5233 is inserted into the other limiting groove 5234, that is, each time the torsion spring 5232 is stressed too large, the limiting block 5233 is separated from the limiting groove 5234, so that the torsion spring 5232 releases the rotation limitation on the anti-skid wheel 5231 to a certain extent, and excessive pulling of the core wire is prevented.

It should be noted that, when the driving member 51 (as shown in fig. 3) drives the clamping mechanism 52 to move towards the motor stator, the second compression spring 5242 is compressed under force until the second compression spring 5242 is compressed to a certain extent, so that the clamping mechanism 52 is driven to push the core wire to move along the winding direction thereof to tighten, thereby forming a force buffering structure, and preventing the core wire from being damaged due to overlarge force in a short time due to too fast driving of the driving member 51.
As shown in fig. 5-7, the clamping mechanism 52 comprises an adjusting mechanism 526 and two clamping blocks 521, a position control mechanism 525 for adjusting the distance between the two clamping blocks 521, and the adjusting mechanism 526 for driving the two clamping blocks 521 to move in opposite directions so as to push the core wire wound on the motor stator to tighten.
