Coil winding tool

Abstract

The coil winding tool can stretch out and draw back and machine various special shapes and comprises a bottom plate, splice plates and a pointer, the bottom plate is provided with regularly-arranged bottom plate screw holes, each splice plate is provided with splice plate screw holes, the splice plates are spliced into a whole plate according to the circumference to be installed on the bottom plate, and the pointer is arranged on the bottom plate. A linear sliding groove is formed in the position, on the outer side of the whole plate, of the top face of the bottom plate, a scaleplate with scales is arranged on the outer side of the linear sliding groove, a pointer capable of sliding along the sliding groove is installed in the sliding groove, a plurality of grooves are formed in each splicing plate, and after the grooves are spliced into the whole plate, each groove forms a complete whole-circle winding track. By means of the scheme, the problems that in the prior art, trial manufacturing of coils in the research and development stage is inconvenient, the performance reliability is affected, and the workload of tool designers is increased are solved, and the technical effects that use is convenient, the winding requirements of coils of different shapes and sizes are met, and the product tool manufacturing cost is saved are achieved.
