Locomotive capacitor square shell Welding device for centre joint
Technical field
The present invention relates to a kind of locomotive capacitor manufacturing equipment, specifically a kind of locomotive capacitor square shell Welding device for centre joint.
Background technology
In the production process of oil-immersed water-cooled high-power locomotive capacitor, square electric container shell adopts the moulding of aluminium sheet fabrication conventionally, therefore, and the middle seam welding operation that is absolutely necessary.The shell gap of this operation welding at present adopts artificial welding conventionally, because the factors such as technology, experience there will be soldered solder joint non-uniform phenomenon unavoidably, causes product quality influenced, even occurs substandard products.The disclosed locomotive capacitor shell seam welding machine of CN102407407A is not suitable for middle seam welding.
Summary of the invention
The object of the invention is for the deficiencies in the prior art, a kind of locomotive capacitor square shell Welding device for centre joint is provided, can be used for welding easily in locomotive capacitor square shell and stitch, and solder joint is even, welding quality is good.
For foregoing invention object, the technical solution used in the present invention is:
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.

the specific embodiment
Shown in structure knot Fig. 1, Fig. 2 of the present invention and Fig. 3:
Jig 1 lower end is plane, is provided with the strip welding groove 11 passing through for welding gun in the middle of jig 1, and the length of welding groove 11 is not less than the length of square electric container shell middle seam to be welded.
Support 2 is connected in jig 1 lower end, has two side stands that be arranged in parallel with welding groove 11 21,22 to form with the horizontal support 23 of welding groove 11 with vertical.Horizontal support 23 and two side stand 21,22 one end are connected, and make support 2 form the framework with an openend 7, and capacitor case can be by openend 7 turnover jig 1 belows.Support 2 bottoms are provided with feet 24.
Overarm 6 is arranged on jig 1 below, hangs oneself from a beam 6 parallel with welding groove and be positioned at two side stands, 21,22 centres, and hanging oneself from a beam 6, to be positioned at carrier openings end 7 unsettled, and the other end is fixed on the horizontal support 23 being connected with two side stands 21,22.
In overarm 6, along welding groove 11 length directions, be fixed with several vertically disposed jacking cylinders 31, raising plate 3 is fixed on the piston rod part of jacking cylinder 31, the stroke of jacking cylinder 31 is enough to make raising plate 3 to rise to jig 1 lower end, raising plate 3 is not less than the length of square electric container shell middle seam to be welded along the length of welding groove 11 directions, the width of raising plate 3 is less than the width on limit, square electric container shell middle seam place to be welded, and capacitor case can be sleeved on raising plate 3 by overarm 6 one end.Raising plate has the groove parallel with welding groove 11 32 in the middle of 3 upper ends.In raising plate 3, have cooling water channel, raising plate 3 belows, two ends are provided with water-in and water-out interface 33,34.
Location-plate 4 is the section bar that a cross section is square frame-shaped, is arranged on raising plate 3 one sides, and is fixed on side stand 21 by a pair of horizontal displacement adjusting device.Each displacement adjustment device is comprised of handwheel 42, screw mandrel 41 and feed screw nut 43, feed screw nut 42 is fixed on side stand 21, screw mandrel 41 with feed screw nut 42 to be threaded, screw mandrel 41 one end extend in side stand 21 and are connected with location-plate 4, and handwheel 42 is fixed on screw mandrel 41 other ends in side stand 21 outsides.Rotation hand wheel 41 can regulate location-plate 4 with respect to the horizontal level of side stand 21.
Clamping plate 5 is arranged on raising plate 3 opposite sides, and side stand 22 outsides are fixed with several horizontally disposed jacking cylinders 51, and the piston rod of jacking cylinder 51 extends in side stand 22, and clamping plate 5 is fixed on the piston rod part of jacking cylinder 51.
Operation principle is as follows:
As shown in Figure 4, in square electric container shell 8, stitching position is upwards sleeved on raising plate 3 by the openend 7 of support 2; Start jacking cylinder 31, capacitor case 8 is risen to jig 1 lower end; Then rotation hand wheel 42, by screw mandrel 41 running fix plates 4, make the middle seam of capacitor case 8 be positioned at welding groove 11 under; Restart horizontal jacking cylinder 51, by mobile clamping plate 5, capacitor case 8 is held out against on location-plate 4.In 11 pairs of capacitor cases 8 of strip welding groove that operating personnel's hand torch 9 passes through, seam carries out welding operation.In welding simultaneously, by entery and delivery port 33,34 to the interior conveying cooling water of raising plate 3.
