Detailed Description

As shown in fig. 1 to 3, a clamping mechanism for drawing an electromagnetic wire comprises a wire coil 1 for winding the electromagnetic wire, wherein the clamping mechanism is arranged on the top of a wire spool of the wire coil 1 and on one side close to the end part of the wire coil 1, and a coil on the wire coil 1 is clamped and fixed through the clamping mechanism. Specifically, clamping mechanism includes fixed block 2 with 1 tip fixed connection of drum, and fixed block 2 is the arc, connects pinch-off blades 3 through adjustable telescopic machanism on the inner terminal surface of fixed block 2, and pinch-off blades 3 be with 1 spool assorted arc of drum, and be equipped with evenly distributed's clamping protrusion 31 on the inner terminal surface, should press from both sides tight protrusion 31 and adopt rubber materials to make, can prevent the electromagnetic wire scratch. The clamping plate 3 moves downwards to clamp the coil under the action of the adjustable telescopic mechanism, and the clamping protrusions 31 can increase the clamping friction force and ensure the clamping effect.

Concretely, adjustable telescopic machanism is including fixed mounting in the regulating box 4 of terminal surface in fixed block 2, regulating box 4 is inside to be equipped with the driving gear 41 of rotation connection, the gear shaft of driving gear 41 stretches out from regulating box 4 and connects miniature power motor 42, driving gear 41 lateral part is equipped with one end tip and regulating box 4 roof fixed connection's telescopic sleeve 43, the outer pole of telescopic sleeve 43 is close to driving gear 42 one side and is equipped with the opening, the lateral part of the interior pole of telescopic sleeve 43 is equipped with the rack of being connected with driving gear 42 meshing, the interior pole of telescopic sleeve 43 stretches out the outer terminal surface of connecting clamping plate 3 from regulating box 4.
