Incorporating the hammer tip spring insertion device to hammer tip cutting machine dedicated machine

摘要

PROBLEM TO BE SOLVED: To stably feed a hammer without making a spring bend or fall and without dispersing ball flying so as to enable control with the program of an NC turn table in a device for pressing a spring into the top of the hammer.;SOLUTION: This dedicated working machine integrating hammer top spring inserting device in hammer top cutting machine has functions for attaching a hammer top spring press-in portion cutter for PACHINKO ball shooting and a spring holder on the cutlery stand of the NC turn table, matching the center of the spring holder with the spring inserting part of the worked hammer by moving the cutlery stand after cutting the top of the hammer, linearly inserting a spring to a point where the outer diameter of a hammer top pin and the inner diameter of the spring are matched, and afterwards fastening the spring with a specified rotation with the relative movement of the hammer top pin and the spring by the element wire diameter pitch of the spring, and pulling the spring holder out of the spring by backward-rotating the relative movement of the hammer top pin and the spring holder after the end of fastening.;COPYRIGHT: (C)2002,JPO
