The invention relates to a
machine head clamp for an automatic threading
machine for producing a magnetic iron core coil of a network
transformer. The
machine head clamp comprises a transverse frame,a top seat, a base and guide assemblies, wherein the top seat is installed at the top of one side of the transverse frame, the base is installed at the top of one side of the transverse frame, an airpressure rod is installed in the middle of the top side of the top seat, and a lifting seat is installed at the telescopic end of the air pressure rod and located below the top seat. According to theinvention, one end of a
copper wire is placed between two movable clamping blocks,
copper wires with different wire diameters are clamped and fixed through the work of a second
servo motor, at the moment, a first
servo motor drives a first
threaded rod in a first sliding groove to rotate, a sliding seat is driven to move along the first
threaded rod, the
copper wire penetrates through the space between the top seat and the base, then the air pressure rod on the top seat extends to drive the lifting seat to descend, and the
copper wire is limited between the guide assemblies of the top seat andthe base, so that the
copper wire can be guided in the subsequent
magnet core coil
machining process, and it is guaranteed that the
copper wire is regularly wound on the
magnet core coil.
