Coil compacting mechanism used during transformer coil winding

Abstract

The invention provides a coil compacting mechanism used during transformer coil winding. A rotating shaft forming a radial compacting mechanism of the coil compacting mechanism is arranged on a longitudinal bearing block through a bearing, and the lower end of the rotating shaft is fixedly connected with a mounting seat; a hollow double-screw bolt is arranged in the mounting seat and connected with the mounting seat through a left-hand thread, and the hollow double-screw bolt and the mounting seat are tightly locked together through a bolt; a left-hand thread at the upper end of a left-right-hand thread sleeve is connected with the lower end of the hollow double-screw bolt, and a right-hand thread at the lower end of the left-right-hand thread sleeve is connected with an inner screw rod; the outer diameter of the inner screw rod is smaller than the inner diameter of the hollow double-screw bolt, and the inner screw rod is coaxially arranged with the hollow double-screw bolt; a guidance key is arranged in the left-right-hand thread sleeve to provide guidance for the inner screw rod; the left end of a transverse roll shaft is connected with the lower end of the inner screw rod; a transverse roll is arranged at the right end of the transverse roll shaft; and an axial compacting mechanism comprises a compacting plate bearing block arranged on the right side of the mounting seat, and a compacting plate arranged at the right end of the compacting plate bearing block. The coil compacting mechanism ensures the contact with a cable surface, and performs secondary compaction on a lower-layer cable; and the height adjustment of the transverse roll is convenient.

Description

technical field [0001] The invention belongs to the field of special equipment for electricians, and is used for compressing the coil in the axial and radial directions when winding a transformer coil, and compressing and leveling the coil during the winding process. Coil pressing mechanism for transformer coil winding. Background technique [0002] At present, there are mainly two types of compacting devices equipped on transformer coil winding equipment with a compacting mechanism at home and abroad: one is to use two vertical rollers and one horizontal roller for compaction, and the other is to use a fixed tilting roller. Angled tapered vertical rollers and a horizontal roller for compaction. The two methods are suitable for different winding processes, and both have different pressing effects. [0003] Among them, a compacting device with two vertical rollers and one horizontal roller is used, the two vertical rollers perform axial compression on the wire, and the hori...

AI Technical Summary

Problems solved by technology

[0006] The purpose of the present invention is to provide a coil pressing mechanism for winding transformer coils, so as to solve the problems of the pressing device described in the background art, such as easy slipping of the lower cables and inconvenient height adjustment during the pressing operation. And the problem of poor linearity of cable winding caused by point contact
