Description

A head-twisting device for a flat-wire motor capable of layered head twisting

Technical Field

The invention relates to the technical field of flat wire motor processing, and in particular to a head twisting device of a flat wire motor capable of layered head twisting.

Background Art

The main power source of new energy vehicles is electricity. As people's environmental awareness continues to increase, the demand for new energy vehicles is also increasing. In new energy vehicles, electric motors are mainly used to generate electricity. Therefore, improving the efficiency of motor production is the top priority for the development of new energy.

In the motor manufacturing process of new energy vehicles, it is necessary to produce motor products with different twisting angles according to different needs. In the existing twisting equipment at this stage, 8 servo motors are generally required to twist 8 layers of copper wire, which greatly increases the production cost of the motor, and the twisting mold cannot be replaced at will. Only one type of wire can be twisted, resulting in a significant reduction in work efficiency, which cannot meet the increasing demand for motors in new energy vehicles. For example, the utility model patent with application number 202120694836.1 discloses an expandable flat wire card-issuing motor stator automatic twisting machine and twisting mold and twisting mold, including a workbench, on which a twisting mold mechanism, a workpiece positioning mechanism and a workpiece follower mechanism are installed from left to right in sequence; the twisting mold mechanism includes a shell, and the inner shaft of the shell is connected to a plurality of concentrically arranged twisting molds, and the twisting mold is connected to a rotating power device. The utility model consists of a 6-axis independent servo power mechanism group, which can meet the simultaneous twisting requirements of a 6-layer wire stator at all angles (spans) and in all directions; it can also be expanded as needed to adapt to the twisting process requirements of an 8-layer wire stator with the 5th and 7th layers of the outermost 4 layers having the same angle (span) and direction, and the 6th and 8th layers having the same angle (span) and direction, and a flat wire protection structure is provided to effectively prevent damage to the outlet terminal when the flat wire is twisted.
