Technical field
The present invention relates to laser weld field, specifically a kind of sheet laser welding mounting and clamping system, belongs to Laser WeldingConnect field.
Background technology
Laser welding technology has that action time is short, efficiency is high, speed is fast, it is little to be out of shape, weldquality is high and welding precisionThe feature such as high, easily to be automated, just progressively replaces biography in fields such as automobile, train, boats and ships, Aero-Space, machine-buildingSystem Arc Welding Process, and be widely used.
Along with the development and popularization of various new materials, the application of thin-plate element is increasingly extensive, particularly in space flight and automobile workIn industry, for the consideration of weight reduction, lifting power, adopt in large quantities thin-slab structure part; While is along with the one-tenth increasingly of laser technologyRipe, the application of laser weld in sheet member more comes approximately wide, has huge application prospect. Laser beam welding is to add fastHot and cold is process but, adds the easy unstability of upper thin sheet, and post welding distortion becomes one of subject matter limiting its application. In addition, in realityIn the application of border, plate sheet welding General Requirements penetration weld, this makes to ensure that laser welding processes full penetration stability is necessary often,The welding of especially long weld seam, this just must consider the clamping problem of sheet member, the quality of clamping tends to Welding StructureProduce serious influence. Especially in the time of welding thin plate (< 1mm), the distortion in its welding process is unavoidable, the dress of weld jigFolder quality is an emphasis always, in welding process, can, because heat input fast and output produce very large deformation force, pass throughThe fixture operating manually tends to because of filling not clamping, and has influence on welding effect. And each test all needs to expendMost time is removed clamping test specimen, expends a large amount of working times, affects operating efficiency.
With 6kw optical fiber laser, welding 0.5mm thick stainless sheet steel is example, before welding by manual operations in the pastFrock clamp clamping work pieces, and from visually observing the gap between workpiece, to guarantee to reach minimum clearance, but by welderingThe same test parameters of rear Quality control also can reach different welding effects, and a weld seam diverse location in exemplarWelding effect sometimes gap can be very large, and welding quality can not get reliable guarantee, and the test of every pair of exemplar all needs to spend greatlyThe time of amount, on clamping, greatly reduces the efficiency of work. Therefore, a kind of new system of exigence solves above-mentioned technologyProblem.
Summary of the invention
The present invention, just for the technical problem existing in prior art, provides a kind of sheet laser welding mounting and clamping system,This entire system is simple in structure, easy to operate, by vacuum suction system, thin plate welded is subject to all the time in welding processUniformly, the mounting and clamping system of larger negative pressure, and by structural design cleverly, guaranteed weldquality, improved workMake efficiency.
To achieve these goals, the technical solution used in the present invention is that a kind of sheet laser welds mounting and clamping system, its spyLevy and be, described mounting and clamping system comprises laser Machining head, fixture cavity base, and be connected with fixture cavity base by pipelineThe vacuum suction system connecing, is also provided with end cap on described fixture cavity base. By vacuum suction system, make thin plate weldedIn welding process, be subject to all the time uniformly, larger negative pressure, prevent due in sheet laser welding process due to too fastThe problem of hot input and output and clamping stability, and the thin plate producing distortion, the vacuum that vacuum suction system produces can reach88KPa, has further guaranteed the stability of the quality of thin plate in welding process.
As a modification of the present invention, described fixture cavity base is high-strength steel material, and inside is set to cavity structure,On its sidewall, have through hole, be connected with vacuum absorption device by pipeline.
As a modification of the present invention, described end cap is high-strength steel material, and wide 2mm is opened in the centre of end cap, thick 5mm left and rightGroove, and drive a certain amount of manhole in the both sides of groove, every side two row through holes are opened corresponding square through hole at its sidewall, and mixCorresponding slidable, controls the break-make of manhole by the slip of catch in corresponding square through hole.
As a modification of the present invention, described end cap and cavity base seal by welding, and weld pitch end capThe about 1-2mm of sidewall square through hole, convenient operation.
As a modification of the present invention, the quantity of described manhole can be determined according to the size of corresponding mounting and clamping system.
With respect to prior art, advantage of the present invention is as follows, and 1) overall structure is simple, easy to operate, cost is lower; 2) originallyThe cavity base of invention is cavity structure, is connected with upper end cover by welding, reaches sealing effectiveness, and assembly structure is simple; 3) originallyInvention adopts vacuum suction system, and intelligent degree improves greatly, by the break-make of vacuum switch control vacuum generator, is easy toManual operation, has reduced a large amount of workloads for clamping, has improved operating efficiency; 4) the present invention opens by the end cap both sides of slottingThe form in hole, makes exemplar test plate (panel) in welding process, the negative pressure homogenising being subject to, and intensity is constant all the time, and control accuracy is high,Improve the stability of welding process.
