Angle pressure device on outer rotor winding machine

Abstract

The invention discloses an angle pressure device on an outer rotor winding machine, which is characterized by comprising a pair of angle pressure mechanisms oppositely arranged up and down, wherein each angle pressure mechanism consists of a forward linear motion pair, a lifting linear motion pair and an angle pressure structure arranged on the lifting linear motion pair; each forward linear motion pair comprises a forward stepping motor, a forward ball screw connected with the forward stepping motor, a forward screw connecting block in threaded connection with the forward ball screw and a forward guide rail which is arranged perpendicular to the rotating axis of a winding machine rotor indexing; each lifting linear motion pair comprises a lifting stepping motor, a lifting guide rail and a gear transmission mechanism connected between the lifting stepping motor and the corresponding angle pressure structure; and operating surfaces of the upper and the lower angle pressure mechanisms correspond to the position of a stator cable channel on the winding machine rotor indexing. According to the invention, due to the arrangement of the pair of angle pressure mechanisms which are symmetrical up and down, the winding displacement and the compression of a stator coil are implemented and the performance of the finished product coil is improved.

Description

technical field [0001] The invention relates to a winding machine for an induction coil, in particular to a pressure angle device on an outer rotor winding machine. Background technique [0002] When producing the motor rotor, there is a process of winding the enameled wire into the groove of the rotor. At present, the rotor with fewer grooves in the production line is produced by an ordinary motor rotor winding machine. However, there are more grooves in the production line. When the rotor is used, such as the outer rotor of the battery car (the rotating part (rotor) of the motor is the outer shell of the motor, and the shaft end of the motor is fixed, it is used to fix the motor.), due to the small gap in the line groove, so , the existing ordinary motor stator winding machine can not meet the production requirements, and must also be produced by manual winding, the production efficiency is low, generally a stator takes 15 to 20 minutes, and the product consistency is poor...

), due to the small gap in the line groove, the existing ordinary motor stator winding machine cannot meet the production requirements, and must also be produced by manual winding, and the production efficiency is low. Generally, it takes 15 to 20 minutes for a stator , and the consistency of the product is poor, the quality cannot be guaranteed

[0003] In order to increase the speed of winding, special outer rotor winding machines are also used for winding, and a servo motor is used to drive the cam transmission pair to complete the winding. On the outer edge of the stator, adjacent line grooves need to be wound crosswise when winding, that is, circular winding in the first and second line grooves, then circular wi
