A winding wire insulation layer ring cutting device and a ring cutting system using the device

Abstract

The invention belongs to the technical field of winding wire quality detection, and in particular relates to a winding wire insulation layer ring cutting device and a ring cutting system using the device. The ring cutting device includes a frame on which a locking assembly and a ring cutting assembly are arranged respectively. The locking assembly includes two sets of claws. The two sets of claws are coaxial with each other so that the winding wire can pass through the axial direction of the claws and Clamped by the claws; two sets of claws are rotatably assembled on the frame; the ring cutting assembly includes a ring cutter, and the cutting edge of the ring cutter points to a section of winding wire between the two sets of claws; The ring cutting assembly also includes an elastic pressing part for applying a load force to the ring cutting knife in the direction of the winding wire so as to cut through the insulation layer; the ring cutting device can improve the working efficiency of the ring cutting operation of the winding wire insulation layer , The quality of the finished product after circumcision can also be effectively guaranteed. The circumcision system also includes a current detection device to further improve the automation of the entire circumcision process and the accuracy of later detection.

Description

technical field [0001] The invention belongs to the technical field of winding wire quality detection, and in particular relates to a winding wire insulation layer loop cutting device and a loop cutting system using the device. Background technique [0002] With the rapid development of high-end electric vehicles, high-speed trains, ships and ships, aerospace, and heavy-duty equipment such as high-power high-speed machine tools and heavy-duty engineering equipment, high-performance motors are proposed with large driving torque, high current density, and high power. New requirements for miniaturization and miniaturization. The high-performance, miniaturized and lightweight motor technology represented by flat wire motors has higher efficiency than traditional permanent magnet synchronous motors, higher power in the same volume, extremely high slot full rate, and lower copper loss, making it more suitable for It is widely used in high-precision technical fields such as drive ...

AI Technical Summary

Problems solved by technology

At present, the traditional ring cutting method is mainly manual cutting, that is, the operator holds a thin blade around the winding flat wire to cut the insulation layer, which is not only inefficient and time-consuming, but also has the following problems: First, the cutting direction Can not guarantee

When the thin blade circles the flat wire, it is often unable to form a perfect closed loop due to the vibration of the wire body or manual cutting errors.

Second, the cutting depth cannot be guaranteed, resulting in scratches on the surface of the conductor with different depths, which greatly affects the accuracy of later experimental data

Third, the thin blades are matched with thin flat wires, and it is easy to scratch your hands if you are not careful during operation, which poses a great safety hazard

Obviously, the above-mentioned manual circumcision method can no longer meet the high-quality and high-precision detection requirements of copper flat wires in the current high-speed development of industrial technology, and it needs to be solved urgently.
