Description
Technical field
The present invention relates to welder, particularly relate to a kind of vehicle body automatic soldering device.
Background technology
Automotive vehicle total-assembly welding line is when processing the solder joint that gusset shirt rim connects with lower body, and the mode taked generally is divided into human weld and automatic welding two kinds.Along with the labor productivity of modern plant is more and more higher, to the more and more attention of labour protection, human engineering, traditional human weld's mode gradually replace by the automatic welding mechanism of mechanization.In the middle of this, successively there is the welding manner that fixed single-point automatic welding, sliding multiple spot automatic welding etc. are different again in car skirt automatic welding mechanism.At present, sliding multiple spot automatic welding is applied the most general at shirt rim welding region, its advantage is the solder joint that single device can realize many (utilization rate of equipment improves greatly), equipment cost is relatively low, can by the solder joint of program continuous print welding skirt region, interval time is short, and production efficiency is high.
Fig. 1 is the comparatively general car skirt automatic welding mechanism of wherein a kind of application, comprises base plate 100, bearing 1, transformer 2; Switching copper coin 3, flexible cable 4, soldering turret 5, guide rail 61 and cylinder 71; Its operation principle drives the bearing 1 that soldering turret 5 is housed to carry out straight reciprocating motion with cylinder 71, bearing 1 carries out straight reciprocating motion by slide block along guide rail 61, carry out control cylinder position of rest by travel switch or proximity switch, get ready at the enterprising electricity that works of several position of rests.
Said mechanism has two larger drawbacks:
First drawback is that cylinder 71 drives and may be subject to source of the gas pressure influence, cause the fluctuation of piston rod pace, add in whole stroke and need constantly to start and stop, once there is the sudden change of speed, may be too short due to the inductive switch triggered time, cause and cannot stop cylinder action (this mechanism does not have rigid limit at position of rest) in time, cause solder joint solder skip or dislocation welding.Cause to subsequent work stations and very large reprocess pressure;
Second drawback is transformer 2 is be fixed on base plate 100, and switching copper coin 3 is drawn from transformer 2 and come soldering turret near zone, then connects copper coin and soldering turret 5 by flexible cable 4.This design, nonstandard stud connector design amount is many, processing capacity large, and needs switching repeatedly, once the laminating of copper piece mating surface is not tight, easily causes sparking, ablation; And the space that this mode takies is also large, cause spelling platform fixture layout crowded; In addition, the soldering turret 5 of the copper coin be connected and fixed with flexible cable and motion, in soldering turret 5 motion process, flexible cable 4 sweeping space is large and be difficult to the movement locus controlling it, easily and the interference such as other frock clamps, initial point limit switch, cause fault or damage, maintenance maintenance cost is high.So this mechanism can only be applied in less stroke, under the prerequisite that spot pitch is identical, namely welding is counted and is limited to.
Fig. 2 is the comparatively general car skirt automatic welding mechanism of another kind of application, comprises base plate 100, bearing 1, transformer 2; Switching copper coin 3, flexible cable 4, soldering turret 5, leading screw 62 and servomotor 72; Its operation principle drives the bearing 1 that soldering turret 5 is housed to carry out straight reciprocating motion on guide rail with ball-screw sliding pair, accurate control cylinder position of rest is carried out by the acting in conjunction of servomotor 72 and ball-screw sliding pair, as long as numbering control program, soldering turret 5 just accurately can arrive and get position of rest ready, repetitive positioning accuracy is very high, and stability is also very good.But equally also there is the second point drawback of the first mechanism in this slippage automatic welding mechanism, namely transformer 2 is fixed on base plate 100, switching copper coin 3 needs to extract from transformer 2, then to soldering turret 5 near zone, then connect copper coin and soldering turret 5 by flexible cable 4.This design makes the second mechanism the same with the first mechanism, not only welding is counted and is subject to limiting to (it is too large that stroke cannot do), and soldering turret 5 is when moving, water air pipe wire harness easily and frame for movement interfere (travel switch and the origin switch of especially easily encountering screw mechanism sensitivity), pipeline is easily caused to wear and tear, to leak gas leakage, control fault etc.Especially flexible cable 4 bends repeatedly, very easily causes insulated hull damaged, or even the fracture of copper core, causes great potential safety hazard and cost loss.
