Abstract
The utility model relates to coil winding jig technical field, especially a kind of skeletonless air-core coil winding jig, solve the copper line tight skeleton plastic deformation shrinkage in prior art, winding operation is completed and will appear the situation of over-tight winding, again because too tight reason, personnel take down by manual mode have certain difficulty, so it is inconvenient for production application, more inconvenient for personnel to quickly and easily take down the problem of wire package.A kind of skeletonless air-core coil winding jig, including short rod, the side of short rod is provided with long rod, the outer ring of short rod and the outer ring of long rod are all sleeved with baffle, the side of long rod is fixedly connected with screw rod, the one end of short rod is equipped with the through hole compatible with screw rod.The utility model makes personnel can quickly for wire package to be taken down or installation operation, reduces the friction between jig, so that personnel is convenient to take down wire package, saves personnel time, also can give enough tightness between jig.
