Abstract
The utility model discloses a pliers spot welding head, including two upper and lower electrode connecting rods, the interlude of two upper and lower electrode connecting rods is equipped with two upper and lower connecting plates respectively, it is together articulated mutually between the two upper and lower connecting plates, the afterbody of two upper and lower electrode connecting rods is equipped with upper and lower hinge hole respectively, be connected with the cylinder between the two upper and lower hinge hole, be equipped with the hinge pedestal on the up end of cylinder, it has the swing arm to articulate on the hinge pedestal, the tip of swing arm has the stopper, be equipped with semicircle tube -shape curved surface on the lateral wall of stopper, the swing arm can be with the stopper laminating on the outer wall of piston rod through the rotation. The utility model discloses can the upper and lower activity interval of adjust the cylinder piston rod, cylinder operating pressure is effectively alleviated to the protection cylinder.
Description
Technical field
The utility model relates to a kind of pliers spot welding head.
Background technology
At present, domestic and international most of automaker all adopts resistance spot welding to automobile body welding.Adopt manual welding mode, cost is low but welding quality unstable, and adopts Robot Welding Cell, once have high input, production cost and maintenance cost high.In prior art, simplification welding equipment exist, the inconvenient operation of mash welder, and between upper and lower electrode spacing adjustment inaccurate, easily make mistakes, and the own temperature of electric welding machine easily raises, service life is short.
Utility model content
The utility model object there is provided one can the upper and lower movable space of adjusting cylinders piston rod, and protection cylinder, effectively alleviates the pliers spot welding head of cylinder operation pressure.
The utility model technical solution problem provides following scheme:
A kind of pliers spot welding head, comprise, lower two Electrode connection bars, it is characterized in that: on described, the interlude of lower two Electrode connection bars is respectively equipped with, lower two connecting plates, on described, together mutually hinged between lower two connecting plates, on described, the afterbody of lower two Electrode connection bars is respectively equipped with, lower pan, on described, cylinder is connected with between lower two pans, the upper surface of described cylinder is provided with articulated column, described articulated column is hinged with swing arm, the end of described swing arm has limited block, the sidewall of described limited block is provided with semi-circular cylindrical curved surface, limited block can be fitted on the outer wall of piston rod by rotating by described swing arm.
The intermediate ends of described upper and lower two Electrode connection bars is installed with hanger bar.
The utility model establishes connecting plate between upper and lower two Electrode connection bars, together mutually hinged by connecting plate, and be provided with adjusting cylinders at the afterbody of upper and lower two Electrode connection bars, articulated column is provided with in the upper surface of cylinder, articulated column is hinged with swing arm, swing arm is provided with limited block, the movement of limited block is controlled by the left and right swing of swing arm, when cylinder piston rod stretches out, and when meeting welding needs, by limited block clamping on the piston rod, prevent piston rod from shrinking, reduce the jacking force of cylinder piston rod, alleviate the operating pressure of cylinder.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
See accompanying drawing, a kind of pliers spot welding head, comprise, lower two Electrode connection bars 1, 2, on described, lower two Electrode connection bars 1, the interlude of 2 is respectively equipped with, lower two connecting plates 3, 4, on described, lower two connecting plates 3, together mutually hinged between 4, on described, lower two Electrode connection bars 1, the afterbody of 2 is respectively equipped with, lower pan 5, 6, on described, lower two pans 5, cylinder 7 is connected with between 6, the upper surface of described cylinder 7 is provided with articulated column 8, described articulated column 8 is hinged with swing arm 9, the end of described swing arm 9 has limited block 10, the sidewall of described limited block 10 is provided with semi-circular cylindrical curved surface 11, limited block can be fitted on the outer wall of piston rod 12 by rotating by described swing arm 9.
The intermediate ends of described upper and lower two Electrode connection bars 1,2 is installed with hanger bar 13.
