Embodiment 1

[0035] as attached Figure 1-6 As shown, the manufacturing method of the stator coil of the AC traction motor specifically includes the following steps:

[0036] S1: Wind the electromagnetic wire into a circular coil; use the circular winding core tooling on the shuttle winding machine. The core diameter of the circular winding core tooling is set according to the total length of the forming coil of different types, specifically: , according to the total length of different types of forming coils under specific working conditions, the winding diameter of the corresponding circular coil, that is, the diameter of the winding core, is derived, and then the electromagnetic wire is wound into a circular shape using the corresponding winding model tooling coil. In order to reduce the manufacturing cost of the winding mold core, those skilled in the art can design the wire winding mold core tooling as a general-purpose tooling with adjustable diameter. The circular coil after the e...

Embodiment 2

[0048] The difference between this embodiment and Embodiment 1 is that in step S1: when the electromagnetic wire is wound into a circular coil, the winding work is carried out on the winding machine of the cylindrical coil, and according to the total length of the required forming coil Size to adjust the diameter of the winding tooling to make a circular coil of the corresponding size.

Embodiment 3

[0050] The difference between this embodiment and Embodiment 1 is that in step S3: in the insulation wrapping of the circular coil, the position of the lead head of the insulation tape is manually adjusted on the workbench and the lead end is wrapped, and then the glue is automatically dispensed by the robot. The method is to carry out the beginning work of the insulation tape on the machine, and then the machine performs the whole machine insulation tape wrapping on the circular coil, and then the robot automatically dispenses glue and automatically cuts the insulation tape to carry out the finishing work of the insulation tape. The automatic dispensing of the robot is specifically as follows: the insulating tape is pulled by the finger of the robot simulator, and after the liquid glue is dipped on the insulating tape, the insulating tape is fixed on the circular coil. The robot automatically cuts the insulating tape specifically as follows: after the robot dispenses glue at t...

Abstract

The invention relates to the technical field of traction motor part manufacturing, in particular to a manufacturing method of a stator coil of an alternating current traction motor, which realizes the full-machine binding function of the stator coil through a method of firstly wrapping and then expanding, reduces the manufacturing process steps of the stator coil and the transfer times of the coil, and improves the production efficiency. The problem that nose parts at two ends of a stator coil cannot be bound by machines is solved. The manufacturing of the stator coil specifically comprises the following steps: winding an electromagnetic wire into a circular coil, removing insulation of a lead, binding the insulation of the circular coil, stretching the circular coil, expanding the coil after stretching, and discharging the finished coil.

Description

technical field [0001] The invention relates to a method for manufacturing a stator coil of an AC traction motor, and belongs to the technical field of traction motor component manufacturing. Background technique [0002] AC traction motors are used as the power of high-speed EMUs, locomotives, urban rail vehicles and other rail vehicles. They have been widely used because of their simple and firm structure, reliable operation, high power and high speed. In the AC traction motor, the stator coil is the core component of its power. With the increase of the production capacity of the current traction motor, the pressure on the production of the stator coil is further increased, especially the bottleneck process of high work intensity - the insulation wrapping process. under great production pressure. [0003] The production process of the stator coil in the prior art is: winding the shuttle wire → wrapping the protective tape → removing the insulation of the lead wire → expan...
