Claims

[Scope of utility model registration request]

A gun body consisting of a pair of front and back plates with a pressurizing cylinder attached to the lower end is supported on a machine base so as to be able to rise and fall freely, and a fixed gun arm and an upper side of the fixed gun arm connected to the piston rod of the pressurizing cylinder are attached to the gun body. a movable gun arm, wherein the upper half of the piston rod located between the pair of plates is formed into a chamfered plane on one side and the other side facing each plate;
Between the pair of plates, a stopper arm extending from the machine side and a power supply plate connected to the fixed gun arm are positioned on one side and the other side of the piston rod, and the movable gun arm is opened in a predetermined manner by the upward movement of the piston rod. The upper half of the piston rod is inserted into the pressurizing cylinder so that the upwardly stepped surface of the lower end of one side of the chamfered piston rod comes into contact with the stopper arm when the upper half of the piston rod is opened in the open position. one side of the upper half is chamfered so that a large diameter thickened portion remains at the lower end, and the stepped surface is formed on the upper surface of the remaining thickened portion, A welding gun device characterized in that the other side surface of the upper half is chamfered so that no large diameter thickened portion remains at the lower end thereof.
