Detailed description of the invention

Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is clearly and completely described.

As shown in Figure 1, Fig. 1 is the exploded view of a kind of stud welding gun disclosed in the embodiment of the present invention, comprise: a pikestaff, its lower end have one to pass for power line and the power line sheath 2 and accessing pikestaff inside for control line through the control line sheath 3 also accessing pikestaff inside; Described rifle body 4 is built-in with and conducts electricity the conductive shaft 6 that copper piece 5 contacts, and the front end of this conductive shaft 6 connects a positioning rod seat 7, this location pole socket 7 has three backstays 8, and described backstay 8 is installed on pole socket 7 side face edge edge, location, and surrounds an equilateral triangle;

And being connected to a pressure regulation device of rifle body 4 rear end, this pressure regulation device can promote described conductive shaft 6 and move towards this conductive shaft 6 front end.

Wherein, described pressure regulation device comprise the linear bearing 9 being located at rifle body 4 Internal back end, the spring 10 being installed on this Bearing inner, spring 10 is fixed on adjusting nut in bearing 9 11 and one and this nut 11 with the use of adjusting screw(rod) 12; The sheathed bead centring ring 14 in rear end of this screw rod 12, this centring ring 14 is fastened in a pressure regulator 15; Described pikestaff is fastened by handle one 1a and handle two 1b and forms, and is provided with gauge tap 16 in it; Be provided with a loudspeaker gum cover 18 in the pole socket 7 of location, this gum cover 18 internal fixtion has a clamp nut 19, and the front end of described conductive shaft 6 has the screw thread coordinated with clamp nut 19, and revolves when welding gun works and be located in clamp nut 19; Bead centring ring 14 is provided with bead 13; Two handles are fixed by cableties 20.
