Description

Technical Field

[0001] The utility model relates to the technical field of hairpin insertion and connection, in particular to a hairpin insertion and connection mechanism. Background Art

[0002] The hairpin insertion and guiding mechanism is an auxiliary structure used in flat wire motor stator production equipment. This guiding mechanism can be used to guide the PIN pins of the hairpin before inserting it into the stator. With the continuous development of technology, people have higher and higher requirements for the manufacturing process of the hairpin insertion and guiding mechanism.

[0003] The existing Hairpin insertion and connecting mechanism has certain disadvantages when used. First, the existing Hairpin insertion and connecting mechanism cannot be easily limited, which can easily cause damage to the product and is not conducive to people's use. In addition, there is a risk that the insulating paper may be damaged by the PIN during the insertion process, which brings certain adverse effects to the actual use process. For this reason, we propose a Hairpin insertion and connecting mechanism. Utility Model Content

During the process, the PIN pin is guided by the guide groove in the guiding rod and enters the slot to complete the tightening and positioning. Finally, the Hairpin and the guiding rod enter the iron core synchronously, which helps the Hairpin to be smoothly inserted into the iron core.

[0007] Preferably, the support body and the slide are positioned by a fixed block, the upper and lower movable components are lifted and lowered on the outside of the slide, and the upper and lower movable components drive the bottom plate, the guide rod fixed base and the Hairpin to lift and lower.

The iron core 9 is positioned by the outer circle and the contoured pin, so that the divergent PIN pins can be tightened to the ideal position for control, ensuring accurate insertion positioning without damaging the product. At the same time, the tooling plays a limit control role on the front insertion end of the PIN pin, so that after the entire Hairpin is inserted into the stator, the size of the PIN pin exposed to the iron core end face is stable and controllable. In addition, the risk of the insulating paper being damaged by the PIN is avoided during the insertion process, which can greatly improve the qualified rate of insertion.
