Description

Technical Field

[0001] The present invention belongs to the technical field of winding fixtures, and specifically relates to a winding fixture for improving winding efficiency. Background Art

[0002] Hollow coils are generally made by winding a single strand of enameled wire. The winding operation of hollow coils is to make the enameled wire rotate around the core rod of the clamp. The existing winding clamps have the problem of not being able to clamp the enameled wire well. Either the clamping force is too small and the clamp cannot clamp the wire. When the winding shaft rotates, the starting wire is too short, resulting in a bad coil, or even the wire is completely separated from the clamp, causing the machine to run idle, reduce production, and waste electricity; or the clamping force is too large, resulting in a small opening angle of the clamp. When the wire is fed in the next working cycle, the wire cannot be fed between the clamp and the rotating shaft, resulting in the failure of the clamping process.

[0003] At present, hollow coils are usually wound using a mold core with a separation block. The outer side is locked with a clamp during winding. After winding, the coil is fixed with a cable tie and then the baffle is released. The detachable mold core is knocked loose before the coil is taken out, which is inefficient. Utility Model Content

[0008] The outer contour shape of the movable clamp is the same as the outer contour shape of the fixed clamp. A rotating shaft is provided on one side of the movable clamp, and a positioning pin is provided on the other side of the movable clamp. Two positioning pins are provided in parallel, and the positioning pins are plugged into the positioning sockets on the end face of the movable slider.
