AI Technical Summary

Technical Problem

The tension adjustment mechanism of existing torque motor winding equipment cannot achieve real-time synchronous linkage with the stator rotation, resulting in a sudden increase in tension of the enameled wire at the corner of the slot, causing enamel film wear and insulation performance failure.

Method used

By employing the synchronous linkage between the clamping swing motion and the transmission unit, and through the coordination of the adjusting slider and the tension spring, the tension of the enameled wire is precisely adjusted. Combined with the dry cleaning unit and the adaptive wire laying mechanism, synchronous tension adjustment and online cleaning of the stator winding are achieved.

Benefits of technology

It effectively reduces the normal positive pressure of the enameled wire at the corner of the slot, improves the insulation reliability and winding tightness of the motor, reduces the wear rate of the winding, and improves the slot fill factor and winding quality of the winding.

Abstract

This invention relates to the field of motor manufacturing equipment technology, specifically a coil winding machine for a torque motor. The invention includes a base, with a horizontal mounting frame and a vertical mounting frame fixedly connected to the top of the base. A damped unwinding roller is rotatably connected to the horizontal mounting frame, and a clamp for fixing the workpiece is rotatably connected to the vertical mounting frame. A pair of fixed tensioning wheels are rotatably connected to the horizontal mounting frame, and a movable tensioning wheel is positioned between the two fixed tensioning wheels. This invention, through the synchronous linkage of the clamp's swing motion and the transmission unit, can precisely drive the adjustment slider displacement to change the effective stroke of the tension spring when the stator swings past the corner of the slot. The transmission slider and transmission rod synchronously reduce the downward tension force of the movable tensioning wheel on the enameled wire, directly counteracting the instantaneous tension peak of the enameled wire at the corner, reducing the normal positive pressure of the enameled wire on the slot corner, thereby effectively mitigating the problem of enamel film damage due to high-pressure friction and improving the insulation reliability of the motor.
