Abstract

The invention relates to a welding clamp. The welding clamp comprises a pedestal, a support column plate, a bearing plate, lower clamping plates, a fixing and clamping device and upper clamping plates, wherein the upper end of the pedestal is vertically provided with the support column plate; the upper end of the support column plate is provided with the bearing plate; the lower clamping plates are fixed on the bearing plate; and the fixing and clamping device is arranged at one end of the bearing plate and the lower clamping plates and is used for pressing the upper clamping plates and the lower clamping plates. The welding clamp provided by the invention makes that the two welded end faces can be kept on one horizontal plane in the clamp, so that the welding is flat, and a weld joint is formed in the middle of the two upper clamping plates; during welding, the welded upper plane is protected by inert gas, and the inert gas of the welded lower plane reaches the space in the middle of the lower clamping plates passing through the support column plate and the bearing plate through a port path, so that the bottom plane of the weld joint is also in atmosphere of the inert gas; and the two planes after welding keep the original gloss.

Description

A kind of weld jig

Technical field

The present invention relates to a kind of weld jig.

Background technology

The infinitely variable speeds part be one (about 195 ㎜ of diameter, wide be 9.8 ㎜, thick be 0.14 ㎜) annulus of the big narrow width thin thickness of diameter; It is the steel alloy that contains more than 10 kind of alloying element with material; The high molybdenum of the nickelic high cobalt of low-carbon (LC) wherein; This material price eighteenth of the twenty is expensive, still need advance article and not have the similar cylindrical material, and then stock utilization is too low as if processing with plate stamping.Earlier thin slice sheet material is welded into cylinder; After through welding, to roll etc. that operation is shaped be a kind of approach of making the electrodeless variable-speed part; When this type of thin type annulus of welding, because the welding precision requirement is very high, so general anchor clamps are can't adapt to the welding of this product.

Summary of the invention

Weld jig provided by the invention is for such special thin type product provides favourable soldering appliance.

The present invention provides following technical scheme:

A kind of weld jig of the present invention comprises base, pillar plate, supporting plate, lower plate, fixed clamping device, train wheel bridge; The pillar plate is vertically arranged in the upper end of said base, and supporting plate is arranged in pillar plate upper end, the last fixedly lower plate of supporting plate; One end of supporting plate and lower plate is arranged fixed clamping device, and fixed clamping device compresses train wheel bridge and lower plate.

Weld jig of the present invention, said fixed clamping device comprises movable part, fixed mount, clip, fixture; Described fixture is the lower plane that is fixedly connected on supporting plate, and movable part becomes " L " shape, and an end of movable part and fixture flexibly connect, and the other end of movable part is arranged fixed mount, and a side of fixed mount connects clip.

Weld jig of the present invention also comprises pad, positive stop strip, reinforcement; Said pad is positioned at the centre of lower plate and train wheel bridge one end, makes the other end of lower plate and train wheel bridge leave the slit; The part of said positive stop strip is arranged in the groove in the middle of the lower plate, and top is positioned at the centre of two train wheel bridges; Said reinforcement is arranged between supporting plate and pillar plate, base and the pillar plate.

Weld jig of the present invention also comprises the inert gas interface, and said inert gas interface arrangement is on the pillar plate, and inert gas gets in the groove in the middle of the lower plate through inert gas interface, pillar plate, supporting plate.

Beneficial effect

Weld jig provided by the invention makes the both ends of the surface that are soldered in anchor clamps, can remain on the horizontal plane, make welding smooth, and weld seam is in the centre of two train wheel bridges; There is inert gas shielding on the last plane that is soldered during welding; The lower plane inert gas that is soldered arrives the space in the middle of the lower plate through interface path pillar plate, supporting plate; Make the baseplane of weld seam that the atmosphere of inert gas also arranged, two planes, welding back all keep original gloss.

The specific embodiment

Below in conjunction with accompanying drawing to further explain of the present invention:

As shown in the figure: a kind of weld jig, comprise base 1, pillar plate 2, supporting plate 3, lower plate 4 is drawn together pad 5, inert gas interface 6, positive stop strip 7, reinforcement 8, fixed clamping device 9, train wheel bridge 10.

Pillar plate 2 is vertically arranged in the upper end of base 1, and supporting plate 3 is arranged in pillar plate 2 upper ends, the last fixedly lower plate 4 of supporting plate 3; Supporting plate 3 is arranged fixed clamping device 9 with an end of lower plate 4.

Fixed clamping device 9 comprises movable part 91, fixed mount 92, clip 93, fixture 94; Fixture 94 is the lower planes that are fixedly connected on supporting plate 3,91 one-tenth " L " shapes of movable part, and an end of movable part 91 and fixture flexibly connect; The other end of movable part 91 is arranged fixed mount 92; One side of fixed mount 92 connects clip 93, and clip 93 compresses train wheel bridge 10, and your fixedly welding work pieces continues.

Pad 5 is positioned at the centre of lower plate 4 and train wheel bridge 10 1 ends, makes the lower plate 4 and the other end of train wheel bridge 10 leave the slit; The part of positive stop strip 7 is arranged in the groove in the middle of the lower plate 4, and top is positioned at the centre of two train wheel bridges 10; Reinforcement 8 is arranged between supporting plate 3 and pillar plate 2, base 1 and the pillar plate 2.Inert gas interface 6 is arranged on the pillar plate 2, and inert gas gets in the groove in the middle of the lower plate through inert gas interface, pillar plate, supporting plate.

Operation principle of the present invention: upper and lower clamping plate leave the slit, and this slit is by the pad decision, is thick 0.02 ~ 0.05 ㎜ that adds of material, through alignment pin, set bolt train wheel bridge, lower plate, pad, supporting plate and pillar plate is fixed; Pillar plate and base plate are fixed; In order to gain in strength, four bosses have been designed; Anchor clamps are through the through hole that leaves on the base plate and the stationary table of bonding machine.

Positive stop strip places the centre of two train wheel bridges, and insert in the slit that an end face of materials to be welded leaves through upper and lower clamping plate, and one that runs into hold down gag behind the positive stop strip is fixed; Take off positive stop strip, insert from the another side slit of upper and lower clamping plate the other end of materials to be welded, and the other end of two solders side contact back hold down gag is solid with it.

Through the inert gas interface, inert gas is charged in the middle groove of lower plate during welding.Welding back hold down gag unloads power, hold down gag is rotated to be lower than solder side then, takes out the end of welding cylinder material well along anchor clamps.
