ある。<Prior art> The conventional swinging device of the spot welding gun 1 is
As shown in the figure, a pair of gun arms 2a and 2b are attached to a support member 3 with a pivot 4 as a fulcrum and can be opened and closed by a pressurizing cylinder 5. A pivoting lever 9, which is rotatably supported by the support member 3 and integrally connected to the support member 3 in the right angle direction, and an end of the piston rod 11 of the pivoting cylinder 10, which is pivotally supported to the bracket 7, are connected by a pin 12. It has a pivoted structure.

決め停止も困難性があつた。 In this case, the center of rotation of the spot welding gun 1 is centered around the pivot 8 of the bracket 7, so the spot welding gun 1 has a large overhang and its turning radius R1 is large. . Therefore, a large rotation space is required for the spot welding gun 1, and since the supporting weight is also large, the output of the rotation cylinder 10 is also required to be large, making the rotation cylinder 10 large and expensive. Due to rotational inertia, it was also difficult to position and stop at a predetermined angle.

In the present invention, a bracket 7 at the tip of a support arm 6 is rotatably supported around a pivot 4, which is a fulcrum for opening and closing the gun arms 2a and 2b. Furthermore, a rotating lever 13 is provided which extends on a line 0 connecting the contact point of the chip when pressurizing the spot welding gun 1 and the center point of the pivot shaft 4, and has one end fixed to the pivot shaft 4. The other end of the piston rod 13 and the end of the piston rod 11 of the rotating cylinder 10 which is pivotally supported on the bracket 7 are pivotally connected by a pin 14.

なる。 Since the present invention has the above-mentioned structure, the opening/closing fulcrum of the gun arms 2a, 2b by the pressurizing cylinder 5 and the piston rod 11 of the rotating cylinder 10 are
The support arm 6 is also the fulcrum for swinging the spot welding gun 1 by moving the rotation lever 13.
This is common to the pivot 4 which is pivotally supported on the bracket 7 at the tip of the . Therefore, the radius of rotation of the spot welding gun 1 becomes as small as radius R 2 around the pivot 4.

いる。<Effect> As described above, according to the present invention, by making the opening/closing fulcrum of the gun arm and the swinging fulcrum of the entire spot welding gun common, the overhang from this fulcrum is reduced, and the supported weight is reduced. Accordingly, the output of the rotary cylinder can also be small, so the size and cost of the rotary cylinder can be reduced. Further, since the rotational inertia is also reduced, stopping at a predetermined position can be achieved with high precision.
Furthermore, the radius of rotation of the spot welding gun is also reduced, which is advantageous in terms of space.
