Abstract

Usage: technological equipment for the manufacture of electric coils. SUMMARY OF THE INVENTION: The clamp 17 acts on the turns of the coil both axially and radially relative to the frame due to the fact that it is self-adjusting. The clamp is coupled to a folding mechanism by a spring-loaded spatial linkage. 4.il.

Description

The invention relates to the field of equipment for the manufacture of electric coils, and is used to wind a wire onto a coil frame. A winding device of this type is used for winding cylindrical coils with conventional, mesh, wave and the like types of laying wires on coil frames used in superconducting magnetic systems of tomographs, charged particle accelerators, inductive energy storage devices and other electrophysical installations .

The aim of the invention is to expand technological capabilities by winding coils of various configurations.

Figure 1 shows a block diagram of a winding device; Fig. 2 is a kinematic diagram of a self-aligning axial clamp of a wound wire; on figs - section aa in fig, 1; figure 4 is a section bB in Fig.Z.

The winding device comprises a mechanism for fastening the frame 1 of the coil, consisting of a spindle 2 with a cone or

faceplate 3 and cone 4 of the tailstock 5, a frame rotation drive that has an electric motor 6, a belt drive 7 and a front headstock 8 with a gearbox, a superconducting wire tensioning mechanism 9, on the output shaft of which a reel 10 with a wound superconducting is mounted wire 11 and a mechanism 12 for laying out the wire, on the shaft of which the guide wire roller 13 is mounted and in the bearings 14 of the housing 15 of which a vertical shaft 16 of the axial clamp 17 of the wire is mounted. At the end of the vertical shaft T6, by means of the hinge 18, the clamping lever 19 is fixed, to the other end of which also by means of the hinge 20 an intermediate fork 21 is connected, with eyes of which on the axis 22 a clamping fork 23 is mounted, in which the axial clamp 17 of the wound wires 11, the Axial clamp 17 is pressed against the surface 25, on which the wire 11 is wound, due to the impact on the clamp lever 19 of the spring 26 with one end attached to the clamp lever 19, and the other end to the bracket 27

the vertical shaft 16. The coiling of the winding wire 11 to the previous wound coil by force P is carried out by a spring 28, one end of the folding mechanism fixed to the bracket 29 of the housing 15 and acting on the bracket 307 with the other end, rigidly connected to the vertical shaft 16, as a result of which the force of the spring 28 is transmitted through the vertical shaft 16, the clamp lever 19, the intermediate fork 21, the clamp fork 23, the clamp 17 on the winding wire 11.

The operation of the winding device is as follows. After installing the frame 1 of the winding coil in the cones 3, 4 and securing the wire 11 on the winding surface 25 of the frame 1, lower the axial clamp 17 onto the surface 25 and bring it along the above surface 25 to the winding wire 11, due to this force P developed by the spring 28, transferred to the wire 11 tightly pressing it to the previous turn. Then, a frame rotation drive is included, which is kinematically connected to the reciprocating system of the wire-folding mechanism 12 to which the wire clamp system is fixed. Thanks to the rotation of the frame 1 and the movement of the mechanism 12 of the wire layout

the windings of the wire 11 on the frame 1 are winded with the winding winding constantly pressed to the previous winded winding.

When using the proposed winding device in the manufacture of superconducting coils of various configurations, a tight winding of wire is provided without inter-turn gaps,
