Description

Technical Field

[0001] The utility model belongs to the technical field of motor winding, and in particular relates to a tension regulating device for winding a motor binding belt. Background Art

[0002] The enameled wire is wound on a winding die and tied with a cable tie, and then the tied enameled wire is placed in the motor stator to form a motor stator assembly. When the enameled wire is wound, a tensioning mechanism needs to be provided at the wire entry end to tension and guide the enameled wire cable to ensure the consistency and tightness of the enameled wire coil.

[0003] Chinese patent CN209562350U discloses a tensioning mechanism of a copper wire winding machine for a motor stator, which belongs to the field of motor stator winding machines. The tensioning mechanism of a copper wire winding machine for a motor stator includes a base plate, a wire support arm and a support plate. The wire support arm is a long rod structure, one end of the wire support arm is arranged on the base plate, and the other end of the wire support arm is inclined upward and is provided with a wire wheel group. A support plate is arranged on the rod body of the wire support arm near the base, and the support plate is supported on the base, and the support plate includes a wire hole.

[0004] When manually controlling the clamping force during manual winding, it is easy to have uneven clamping force or insufficient clamping force.

However, when winding, if multiple sets of winding dies need to be wound at the same time, there is a lack of linkage components between the multiple sets of wire wheel groups, and they need to be adjusted one by one during tension adjustment, which is more troublesome.

[0005] Currently, no effective solution has been proposed for the problems in the related technologies. Utility Model Content
