Description
Technical field
The utility model relates to a kind of resistance spot welding solder joint pick-up unit.
Background technology
Large-area thin plate is being carried out welded structure, as baroque bullet train motor train unit ceiling, adopting stainless sheet steel to be welded, if adopt arc welding method, post welding distortion is one of unmanageable problem.For fear of welding deformation, spot-welding technology is adopted in decision.Spot welding is a kind of discontinuous welding method, and the bond strength of materials to be welded depends on the intensity of solder joint fully.And the intensity of solder joint is subjected to the influence of welding condition, environment temperature, material composition and specification.
Therefore, even same individual adopts identical mode to weld identical member and position thereof, welding quality also usually can change.As seen, the quality of welding spot of each member how controlled well is a very crucial problem, and it directly has influence on the performance of member.
Summary of the invention
For guaranteeing the quality of welding spot of member welding, according to the requirement of process program, Joint Strength detects test before must doing weldering before the welding every day, and the utility model provides a kind of resistance spot welding solder joint pick-up unit that satisfies this experiment.
Resistance spot welding solder joint pick-up unit described in the utility model mainly comprises:
Lifting jack, gear frame, chain hook, bench vice, worktable, petroleum pipeline, support and oil pump;
Wherein bench vice is fixed on an end of worktable, gear frame is fixed on the other end of worktable, lifting jack is positioned at falsework inside, the hydraulic cylinder of lifting jack is fixed on the worktable by support, the piston of lifting jack is fixedlyed connected with gear frame one end, the gear frame other end links to each other with chain hook, and oil pump links to each other with lifting jack by petroleum pipeline.
During work, carry out according to following steps:
1. before the weldering, according to the welding parameter of welding process requirement setting;
2. soldering test solder joint on test plate (panel);
3. wherein an end of a test plate (panel) is clamped with bench vice, and another piece test plate (panel) hangs on the chain hook;
4. gently step on oil pump with pin, the test plate (panel) that the lifting jack promotion hangs with chain hook is moved to the left, and draws back until solder joint;
5. observe solder joint amount of contraction, fracture location, section configuration etc., and whether the diameter of measuring solder joint meet the demands, for referencial use for obtaining qualified solder joint.
As nonconforming, readjust welding parameter, test again according to 2 to 4 steps, till qualified.
Resistance spot welding solder joint pick-up unit described in the utility model can detect Joint Strength before welding every day, to guarantee that the welding quality of product still reaches stable, qualified standard under various reference influences.
In order to obtain better effect, resistance spot welding solder joint pick-up unit described in the utility model can adopt following measure:
1. in the resistance spot welding solder joint pick-up unit described in the utility model, described lifting jack is the pushing-type lifting jack.Its advantage is, can overcome the drawback of pull-type lifting jack tonnage not enough (maximum can only arrive 10 tons); And shortened whole device length, increased the stability of device because the stroke that test specimen is broken is certain, pull-type lifting jack can only design the other end at test specimen, the length of whole like this device will increase 300mm.
2. in the resistance spot welding solder joint pick-up unit described in the utility model, described bench vice is the rotating disc type bench vice.Be adjustable to when inclined to one side consistently when test specimen presss from both sides, guarantee stressed maximum with the center line of lifting jack.
3. in the resistance spot welding solder joint pick-up unit described in the utility model, described oil pump is foot-operated oil pump.Its advantage do not need to be other energy, and pin is stronger than hand, in refueling process, does not influence the work of hand simultaneously.
4. in the resistance spot welding solder joint pick-up unit described in the utility model, described lifting jack is 20 tons.This tonnage can satisfy the holding capacity that requires under the Joint Strength standard.

Number description:
1-pushing-type lifting jack; The 2-chain hook; 3-rotating disc type bench vice; The 4-worktable; The 5-petroleum pipeline; The foot-operated oil pump of 6-support: 7-; The 8-gear frame; The 9-test plate (panel); The 10-solder joint.
Embodiment
In conjunction with Fig. 1,, mainly comprise resistance spot welding solder joint pick-up unit described in the utility model:
20 tons pushing-type lifting jack 1, gear frame 8, chain hook 2, rotating disc type bench vice 3, worktable 4, petroleum pipeline 5, support 6 and foot-operated oil pump 7; Wherein rotating disc type bench vice 3 is fixed on an end of worktable 4, gear frame 8 is fixed on the other end of worktable 4, lifting jack 1 is positioned at falsework 4 inside, the hydraulic cylinder of lifting jack 1 is fixed on the worktable 4 by support 6, the piston of lifting jack 1 is fixedlyed connected with gear frame 8 one ends, gear frame 8 other ends link to each other with chain hook 2, and foot-operated oil pump 7 links to each other with lifting jack 1 by petroleum pipeline 5.
Before the weldering, according to the welding parameter of welding process requirement setting; Soldering test solder joint 10 on test plate (panel) 9 then; Wherein an end of a test plate (panel) is clamped with rotating disc type bench vice 3 again, and another piece test plate (panel) hangs on the chain hook 2; Then gently step on foot-operated oil pump 7 with pin, lifting jack 1 promotes gear frame 8, and the test plate (panel) that hangs with chain hook 2 under it drives is moved to the left, and draws back until solder joint; Observe solder joint amount of contraction, fracture location, section configuration etc., and whether the diameter of measuring solder joint meet the demands, for referencial use for obtaining qualified solder joint.Under the effect of 20 tons pushing-type lifting jack 1, if solder joint itself is broken, then Joint Strength is below standard, need readjust welding parameter; If near the test plate (panel) itself the solder joint is destroyed, then Joint Strength is up to standard, can carry out the batch welding job of product on the same day.
