Comprise the jig that a lower end is plane, be provided with the strip welding groove passing through for welding gun in the middle of jig, the length of welding groove is not less than the length of square electric container shell middle seam to be welded;
The fixing support of jig, support is at least provided with in welding groove length direction one end can be for the openend below capacitor case turnover jig;
Be set in parallel in the overarm of jig below with welding groove, it is unsettled that overarm is positioned at carrier openings end, and the other end is fixed on support;
Raising plate, jacking cylinder by can vertical lift is fixed on overarm upper end, the stroke of jacking cylinder is enough to make raising plate to rise to jig lower end, raising plate is not less than the length of square electric container shell middle seam to be welded along the length of welding groove direction, the width of raising plate is less than the width on limit, square electric container shell middle seam place to be welded;
Location-plate, is arranged on raising plate one side, and is fixed on support by horizontal displacement adjusting device;
Clamping plate, is arranged on raising plate opposite side, and jacking cylinder that can horizontal extension is fixed on support.
In square electric container shell, stitch position and upwards by overarm one end, be sleeved on raising plate, by jacking cylinder by its jacking to jig lower end, adjust position to the middle seam of location-plate and aim at welding groove, then by clamping plate, capacitor case is fixed.Operating personnel's hand torch can carry out welding operation by welding groove centering seam.Welding groove Butt welding gun forms guide effect, makes even weld straight, can improve welding quality.
Further, in the middle of raising plate upper end, have the groove parallel with welding groove.This structure facilitates welding slag and chip to fall to discharging.
Further, have cooling water channel in raising plate, below, raising plate two ends is provided with water-in and water-out interface.By cooling water channel is set in raising plate, can be cooling in time by raising plate butt welded seam both sides workpiece component, prevent hot-spot, can eliminate welding stress.
Beneficial effect of the present invention is: capacitor case is installed convenient fixing, and middle seam and welding groove accurate positioning, and even weld is straight, and welding slag can be discharged downwards in time, and welding stress is little, and welding quality is good.
