According to the utility model discloses a further embodiment, further include, the supporting station outside extends and is equipped with the portion of bending. The bending part and the inner wall of the rotary drum simultaneously position the shifting fork body, and the shifting fork body is more stably installed.
According to the utility model discloses a further embodiment, further include, it is equipped with the constant head tank to lead electrical pillar below middle part, just the head profile phase-match of constant head tank and bottom electrode. When the rotary drum rotates, the cutting-in and cutting-out of the lower electrode are smoother, the contact surface is more attached, and the conductivity is better.
According to another embodiment of the present invention, further comprising, the supporting table has at least six, and the uniform distribution is distributed on the upper end of the drum. The plurality of shifting forks can be conveniently installed or detached by operators at the same time, and the working efficiency is improved.
The beneficial effects of the utility model are that, air chamber shift fork spot welding device fixes on nut spot welder workstation lateral wall, and the axis of leading electrical pillar aligns with the axis of bottom electrode, upper electrode, and the dress can conveniently be hung with the shift fork body to the bottom electrode on the supporting station, and hexagonal weld nut also can be fixed a position by the position sleeve, and hexagonal weld nut is accurate, firm with the relative position of the shift fork body is fixed, and a plurality of shift forks are unloaded to easy to assemble simultaneously, improve shift fork weldment work efficiency.
