(Operation) The operation of the present invention will be explained with reference to FIG.
To change the dot position of the welding gun 2 from point A to point B, the cylinder 6 is actuated to swing the upper link 4 counterclockwise about the pivot 4b relative to the support frame 3; According to this, the pivot shaft 4b moves counterclockwise around the pivot shaft 4a of the link 4 relative to the fixed frame 1 along a predetermined arcuate trajectory, and the support frame 3, and therefore the welding gun 2 to which it is fixed, moves in the counterclockwise direction. It is displaced from the lower movement position to the upper movement position while its posture is controlled by the lower link 5. In this case, since the cylinder 6 moves together with the support frame 3, the support frame 3 can be largely displaced by extending and contracting the cylinder 6 with a relatively small stroke corresponding to the swing angle of the upper link 4 with respect to the support frame 3. becomes possible. Also, welding gun 2 is connected by links 4 and 5.
In order to displaceably support the impact point, the position of the impact point can be easily finely adjusted by using one of the links, for example, the stopper bolts 8 1 and 8 2 that abut on the upper link 4 as in the embodiment, which improves work efficiency. improves.
