As a so-called dual type spot welding gun that performs spot welding at two points at the same time, those shown in FIGS. 1 and 2 are known.
As shown in the figure, a pair of C-shaped spot welding guns 2A, 2 are attached to one common mounting bracket 1.
B is installed in parallel. It goes without saying that the spot welding guns 2A and 2B are each equipped with a gun arm 3, welding tips 4a and 4b, and a pressure cylinder 5.

きず、汎用性に欠けるという不具合がある。 However, according to the above conventional spot welding gun, the distance between the guns 2A and 2B, in other words, the dot pitch remains fixed, so spot welding can only be performed under one limited dot pitch. The problem is that it lacks versatility.
この考案は以上のような点に鑑みて、一対のス

る。 3 to 5 are diagrams showing an embodiment of this invention. As shown in the figure, the aforementioned mounting bracket 1 is divided into a fixed bracket 10 and a movable bracket 11, and a pressure cylinder 5 is held in each of the fixed bracket 10 and the movable bracket 11. The fixed bracket 10 is fixed to the base body 12, and the fixed bracket 10 is
A holder plate 13 is fixed to the upper surface of the holder.

し得る構成となつている。 Guide blocks 14 are provided on the upper surface of the base 12 and the lower surface of the holder plate 13, respectively.
a, 14b are provided protrudingly, and the movable bracket 1
1 is configured to be able to slide in a direction perpendicular to the axis of the pressurizing cylinder 5 while being guided by these guides 14a and 14b.

動ブラケツト１１に連結してある。 Further, a cylinder 15 as an actuator is disposed on the lower surface of the holder plate 13, and a piston rod 15a of the cylinder 15 is connected to the movable bracket 11.
尚、１６および１７は可動ブラケツト１１のス
ライド限位置を規制するストツパーである。 Incidentally, reference numerals 16 and 17 are stoppers for regulating the sliding limit position of the movable bracket 11.

る。 First, when performing spot welding with a narrow dot pitch, the electromagnetic valve 18 is switched to position B in FIG. 4. As a result, the cylinder 15 is actuated, one spot welding gun 2B moves together with the movable bracket 11 toward the fixed bracket 10, and the spacer 19
It stops at the position where it hits the fixed bracket 10 via. By operating the pressurizing cylinder 5 under pressure in this state, spot welding is performed at two points at the same time.

同時にスポツト溶接が施される。 On the other hand, if the dot pitch P is to be widened, the electromagnetic valve 18 is switched to position A in FIG. 4. As a result, the cylinder 15 is extended and the spot welding gun 2B is slid (shifted) together with the movable bracket 11 until it hits the stoppers 16 and 17. In this state, by pressurizing the pressure cylinder 5 in the same manner as above, the spot welding gun 2B
Spot welding is performed at two points simultaneously under a dot pitch that has been widened by the amount of movement.

なる。 In this way, by making it possible to switch the dot pitch into two stages, wide and narrow, it is possible to weld continuously at a certain dot pitch, for example in the welding process of automobile bodies (for example, when the number of panels is locally increased). Conventionally, if the number of dots is large or there is a change in shape, it would be necessary to perform additional dots, but according to the above embodiment, this can be handled by simply changing the dot pitch.
以上の説明から明らかなようにこの考案によれ
ば、適宜打点ピツチを変えてスポツト溶接を行な
えることから、汎用性にすぐれるものである。
As is clear from the above description, this invention has excellent versatility because spot welding can be performed by changing the dot pitch as appropriate.
