A kind of flexibility utilizing Laser Welding to weld always spells system
Technical field
The utility model relates to welding production line field, particularly relates to a kind of flexibility utilizing Laser Welding to weld and always spells system.
Background technology
Vehicle body as one of the large main body of automobile two is more and more subject to the attention of automobile manufacturing company and user.Body of a motor car accounts for 1/5 of whole car fare value.The later stage nineties 20th century, the U.S. proposed body quality " 2mm engineering " and " submillimeter punching press "." submillimeter punching press " research project completes, and this reaches the standard grade for Laser Welding and provides condition, and adopts Laser Welding Welder artistic skill significantly to improve vehicle body shock resistance and fatigue performance, and this is that the enforcement of " 2mm engineering " provides strong guarantee." 2mm engineering " completes in the U.S. at present, but it is less always to spell the application of station Laser Welding for body in white.
At present, domestic and international car manufactures always spells station for automobile body-in-white, main employing spot welding robot welds, adopt spot-welding technology due to the impact by robot body structure and soldering cramping apparatus and erection unit thereof, its welding spatial dimension has certain limitation, cause always spelling station solder joint Limited Number, and spot-welded deflection is large simultaneously, weld seam is coarse.
Application domestic automobile manufacturer for laser welding techniques mainly concentrates on each assembly welding on automobile top-cap, door inner panel, gusset and floor, welding quality can be ensured to a certain extent, but adopt Laser Welding welding procedure at total station of spelling, do not obtain yet applying more widely.
Utility model content
For solving the problem, the utility model provides a kind of automobile body welding that reduces to be out of shape and the flexibility utilizing Laser Welding to weld increasing solder joint number always spells system.
The utility model solves the technical scheme that its technical problem adopts:
A kind of flexibility utilizing Laser Welding to weld always spells system, comprise the total spelling station substrate placing body in white, the both sides of total spelling station substrate are equipped with portal frame, each portal frame is equipped with the laser engine hand of four-degree-of-freedom, each portal frame is provided with at least one laser engine hand, each laser engine hand comprises can along portal frame at the Y-direction slide unit of X to slip, Y-direction slide unit is provided with the Z-direction slide unit that can slide along Y-direction slide unit in Y-direction, Z-direction slide unit is provided with the Z-direction slide block that can slide along Z-direction slide unit in Z-direction, Z-direction slide block is provided with spill spin block and is arranged on the laser welding system on each spill spin block.
Be further used as the improvement of technical solutions of the utility model, total station substrate of spelling is provided with the automobile body clamp being positioned at body in white both sides.
Be further used as the improvement of technical solutions of the utility model, laser welding system is scanning galvanometer or fixed focal length.
Be further used as the improvement of technical solutions of the utility model, each portal frame being positioned at body in white both sides is equipped with two Y-direction slide units.
The beneficial effects of the utility model: this flexibility utilizing Laser Welding to weld always is spelled system and led by arranging three-dimensional moving mechanism on body in white two side portal frame, each laser welding system portal frame being arranged on body in white four orientation can be carried out laser weld by any point moved on body in white, make the welding precision of body in white, weld strength significantly improves, can spell total the welding that station carries out more locus simultaneously, overcome prior welding mode and always spell the less limitation of station solder joint number, which reduce follow-up repair welding, improve production efficiency.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is described in further detail:
Fig. 1 is the utility model embodiment overall structure schematic diagram.
Detailed description of the invention
With reference to Fig. 1, the utility model is that a kind of flexibility utilizing Laser Welding to weld always spells system, comprise the total spelling station substrate 9 placing body in white 8, the both sides of total spelling station substrate 9 are equipped with portal frame 1, each portal frame 1 is equipped with the laser engine hand of four-degree-of-freedom, each portal frame 1 is provided with at least one laser engine hand, each laser engine hand comprises can along portal frame 1 at the Y-direction slide unit 2 of X to slip, Y-direction slide unit 2 is provided with the Z-direction slide unit 3 that can slide along Y-direction slide unit 2 in Y-direction, Z-direction slide unit 3 is provided with the Z-direction slide block 4 that can slide along Z-direction slide unit 3 in Z-direction, Z-direction slide block 4 is provided with spill spin block 5 and is arranged on the laser welding system 6 on each spill spin block 5.
This flexibility utilizing Laser Welding to weld always is spelled system and is led by arranging three-dimensional moving mechanism on body in white 8 liang of side portal frames 1, the each laser welding system 6 portal frame 1 being arranged on body in white 8 four orientation can be carried out laser weld by any point moved on body in white 8, make the welding precision of body in white 8, weld strength significantly improves, can spell total the welding that station carries out more locus simultaneously, overcome prior welding mode and always spell the less limitation of station solder joint number, which reduce follow-up repair welding, improve production efficiency.
As the utility model preferred embodiment, total station substrate 9 of spelling is provided with the automobile body clamp 7 being positioned at body in white 8 both sides.
As the utility model preferred embodiment, laser welding system 6 is scanning galvanometer or fixed focal length.
As the utility model preferred embodiment, each portal frame 1 being positioned at body in white 8 both sides is equipped with two Y-direction slide units 2.
Laser welding system 6 in the total spelling system of this flexibility has four frees degree, comprises three linear degrees of freedom and a rotary freedom.Laser welding system 6 is distributed in portal frame 1 two ends, and such clamp mechanism both also can vertically be delivered to position to be welded in the air by horizontal feed.
Laser welding system 6, by the motion at X-axis, Y-axis and Z axle, can set operating range with in the scope being intended to be applicable to, more can solder joint to reach.
Certainly, the utility model is created and is not limited to above-mentioned embodiment, those of ordinary skill in the art also can make equivalent variations or replacement under the prerequisite without prejudice to the utility model spirit, and these equivalent modification or replacement are all included in the application's claim limited range.
