The length of the support copper billet is greater than the distance between solder joint and support tube end.
The support copper billet include the copper billet ontology of top closure and be arranged in copper billet ontology cooling chamber it is intracorporal
Capillary is connected with cooling water in the capillary, and the return water of export cooling water is equipped between capillary and cooling cavities
Cavity, the section of the return water cavity are annular.
The ratio between the section of the capillary and the sectional area of annular return water cavity are 1:1.
The water outlet of the capillary is inclined-plane water outlet.
The connecting plate is equipped with the limited block to limiting cylinder stroke, and the limited block is L-shaped.
One end of the limited block is fixed by location hole and connecting plate, and can adjusting position, the other end is equipped with
I-shaped cushion block.
Compared with prior art, the utility model has the advantage that
One, improve welding quality: the utility model in fixture base by adding two with retractable supports copper billet
Special tooling, in Tube-sheet Welding, support copper billet is inserted into support tube to be welded, since electric resistance welding can be in welding
Pressure is generated at solder joint, support inside pipe wall to be welded is pushed and is contacted with support copper billet outer wall, and contact rear support copper billet is not only
Play the role of support, also act the effect of additional electrode conduction, increase electric current, improves welding burn-off rate, together
Water cooling inside Shi Peihe effectively prevent copper billet excessive loss, solves too deep weld indentation, burn-through, dry joint and other issues.
Two, reduce process debugging difficulty: relative to direct welding, improved special tooling can obtain bigger weldering
Window is connect, it is more advantageous for welding debugging.
Three, it reduces loss: adding water cooling inside support copper billet, can preferably promote its service life, avoid loss excessively frequency
It is numerous, and inclined-plane water outlet is set by the water outlet of capillary, the flow velocity of water outlet is increased, is effectively reduced at solder joint
Temperature, prevent burn-through and excessive loss.

Specific embodiment
The utility model is described in detail in the following with reference to the drawings and specific embodiments.
Embodiment
As shown in Figs. 1-5, the utility model provides a kind of tooling for body of a motor car Tubesheet Welding, mainly by original folder
Have pedestal 1, clamping unit 3, valve island 4 and newly-increased Tubesheet Welding special tooling 2 to form, Tubesheet Welding special tooling 2 includes pillar
10, cylinder 11, connecting plate 12, support copper billet 13 form, wherein have chilled(cooling) water return (CWR) inside support copper billet 13, inner cavity is equipped with logical
The capillary 15 of cooling water.
The working principle of the utility model is as follows:
After support tube components are placed into clamp, the cylinder of the two sides of tube sheet Coiling Welded Pipe will support copper billet respectively from two sides
It is pushed into support tube cavity, support copper billet plays the role of the transmitting of support and electric current, heat when welding, due to generating when welding
A large amount of heat is passed to support copper billet, will accelerate the loss of copper billet, increases cooling water pipe inside support copper billet and carry out water cooling,
To improve the service life of support copper billet.
As shown in Fig. 2, circled positions are bond pad locations in figure, part A is vehicle window frame, and part B is support tube.
As shown in Figure 3 and Figure 4, after part is put into position, cylinder 11 pushes support copper billet 13 to enter in part B support tube, branch
It supportting 13 length of copper billet to be determined according to bond pad locations, and is just over solder joint, outer diameter is determined according to part B support tube caliber, than
Its caliber is smaller, and when welding, soldering turret keeps certain soldering turret pressure, and passes through high current heating fusing part, supports copper billet 13
Play the role of support, current channel in part B support tube cavity.
As shown in figure 5, leading to cooling water in support copper billet 13, arrow direction is cooling water (flow) direction, and water outlet inclined-plane is upward.
Cooling water is intake from capillary 14, from 14 surrounding aeration backwater of capillary, forms cooling water circulation, carries out water to support copper billet 13
It is cold, avoid overheat cause to be lost it is too fast.
