Hollow coil winding clamp and winding method

Abstract

The invention relates to a hollow coil winding clamp, a cross clamp of the hollow coil winding clamp can achieve power of wire clamping action and clamp loosening action under the action of a clamp pressing air cylinder, the action is simple, and wire clamping is rapid and efficient. The power of the wire clamping action of the cross clamp directly comes from the extension of an air cylinder, an ejector sleeve is a long-strip-shaped cylindrical object, and the arm length can be increased, so that the moment generated under the condition that the spring force is reduced is enough to open the clamp. The hollow coil winding clamp has the advantages of small resistance generated by extension of the pressing and clamping cylinder, large force of the clamp pressing on the enameled wire, good wire clamping effect and the like.

Description

technical field [0001] The invention relates to the technical field of air-core coil winding, in particular to an air-core coil winding fixture and a winding method. Background technique [0002] Hollow coils are generally wound from a single strand of enameled wire. The hollow coil winding operation is to make the enameled wire go around the mandrel of the fixture. The winding fixture of the prior art has the problem of not being able to clamp the enameled wire well, or the clamping force is too small, and the clamp cannot hold the wire. When the spool rotates, the starting thread is too short, resulting in poor coil, or even the thread and the clip are completely separated, causing the machine to run idly, reducing the output, and wasting electricity; or the clamping force is too large and the opening angle of the clip is too small. , the wire cannot be fed between the clip and the rotating shaft, resulting in failure of the wire clamping process. [0003] Therefore, in ...
