Embodiment Construction

[0035] In the embodiments of the drawn arc stud welding torch of the present invention shown in FIGS. 1 to 18 , the drawn arc stud welding torch is mainly composed of two parts: a fixed assembly and a movable assembly.

[0036] The fixing assembly includes a body group, an electromagnet 20 and an anti-splash set. The body group includes a casing 21 , a sliding sleeve 4 fixed in the casing 21 with screws 9 and an end cover 23 fixed at the rear end of the casing 21 . The electromagnet 20 is installed at the rear of the inner cavity of the casing 21 and fixed on the end cover 23 by screws and nuts 22 . The anti-splash cover set comprises an anti-splash cover 91, a locking nut 92, a support frame 93, and a guide rod 94. Anti-splash cover 91 is fixed on the front end of support frame 93 by lock nut 92, and support frame 93 is connected with the front end of sliding sleeve 4 by 2 guide rods 94, and 2 guide rods 94 are parallel with the axis of movable assembly, press plate 30 and ...

Abstract

The invention discloses a drawn-arc type stud welding gun, which comprises a fixed component and a movable component. A stud receiver component and a cylinder piston component are arranged at the middle part of the movable component; the stud receiver component is mounted at the front end of the cylinder piston component, and an arc-shaped screw transporting slide is formed therein; a conducting clamping head of the receiver component is mounted in front of the stud receiver component, the penetrating inner hole thereof is communicated with a screw outlet port of the arc-shaped screw transporting slide and a screw inlet port of the arc-shaped screw transporting slide of the receiver component is communicated with the outside of the welding gun; and a piston rod of the cylinder piston component is coaxial with the inner hole of the conducting clamping head; and when the piston of the cylinder piston component moves forward, the piston rod thereof enters the inner hole of the conducting clamping head through the arc-shaped screw transporting slide of the stud receiver component, and the air passage of the cylinder piston component is communicated with the outside of the welding gun. The drawn-arc type stud welding gun can realize the automatic feeding and loading of the stud welding screws after the automatic feeding device is connected with the stud welding power source, thereby greatly improving the welding speed of the stud welding screws and reducing the labor intensity of workers at the same time.

Description

[technical field] [0001] The invention relates to welding equipment, in particular to a drawn arc stud welding torch. [Background technique] [0002] Stud welding guns are widely used in automobile, shipbuilding, aviation, locomotive and other sheet metal industries. The stud welding gun uses the current output by the welding machine to form an arc between the welding sheet metal parts and the welding studs through the lifting of the electromagnet, so that the welding studs and the sheet metal parts melt at the same time, and then through the control of the controller, the electromagnet is turned off. Current, the conductive end part drives the welding nail to press into the molten pool of the sheet metal part under the pressure of the spring, and the welding is completed at one time. The whole welding process only takes tens of milliseconds. Therefore, the working characteristics of the welding torch are: short time, high frequency, vertical positioning, and good repetiti...
