<P>PROBLEM TO BE SOLVED: To provide a changer that can appropriately insert and hold a contact tip and correct the relative position between a torch and socket and the displacement of rotational center. <P>SOLUTION: The changer 1 includes: a socket 10; a socket rotating means; a pallet 30 in which a socket guide 34 having a guide hole 34a to which the socket 10 is inserted is formed; and an elastic member 37 provided between the socket 10 and the bottom of the guide hole 34a. The changer 1 turns a contact tip together with the socket 10 in normal and reverse directions, and attaches/detaches the contact tip to/from the torch. A tip holding hole 11 is formed at the rotational center of the socket 10, and a positioning section is formed on the bottom of the tip holding hole 11. Furthermore, a slot-like part is formed in an opening of the tip holding hole 11 to be engaged with the contact tip, and the outside diameter of the socket 10 is formed to be smaller than the inside diameter of the guide hole 34a, so that the socket 10 may be freely rotated and tilted to the socket guide 34. <P>COPYRIGHT: (C)2012,JPO&INPIT |
