PURPOSE:To make a transfer device simpler and lower in cost by transferring the work with driving devices for the purpose of working. CONSTITUTION:The back and forth movements in the vertical directions of a welding gun 10 are transmitted to a shift cam member 32, and the member 32 is moved back and forth along a pawl rack 34 in synchronization with the movement of the gun 10. In this way, while a work table 5 is positioned to prescribed positions by a positioning mechanism 44, it is fed intermittently in the direction of an arrow 3 in synchronization with the movement of the gun 10, and stud bolts, etc. are welded automatically in the predetermined positions of the work. When the table 5 is fed in the direction of the arrow 3, a releasing mechanism 56 is operated to release the detent engagement of an engaging pawl part 31 and a detent pawl part 35 as well as the detent engagement of an engaging pawl part 41 and a detent pawl 40, and the table 5 and the work 6 placed thereon are slided on rollers 2 by own weight and are returned quickly. |
