Description
[technical field]
The utility model is about a kind of welding anchor clamps, and You Zhike obtains a kind of welding anchor clamps of tight splicing welding joint.
[background technology]
The welding plate can be formed through laser weld along straight line or curve by the weldment of identical or different thickness, unlike material, different coating more than two or two.In laser weld, material butt joint rather than overlap joint, the weld seam that obtains like this has good characteristic.The appearance of welding plate technology has solved by traditional single thickness material unappeasable ultra width weldment of institute and the material different parts has been had the technological problems that different performance requires, and the panel construction of processing like this can reach the most rational metallic combination.At present; Like extensive use laser assembly solder plate on each position of body of a motor car, like luggage case stiffener, luggage case inner panel, vibration damping mounting, rear wheel cover, side-wall inner-plate, door inner panel, preceding floor, front longitudinal, bumper, crossbeam, wheel cover, B post connector, central post etc.Laser assembly solder plate has obtained widespread usage in the car load manufacturing of each big automobile factory of states such as Europe, U.S.A, day, the automaker has more than 100 welding board assembly line at present and is distributed in all over the world the production that the demand of welding plate has promoted to weld plate greatly.
Automobile weldment great majority are thickness automobile structures at 0.8mm-2.6mm; Like outer covering piece, interior plate, reinforcement etc.; Because characteristics such as its material is very thin, yielding make in the practical laser welding; The welding difficulty is big, and the welding fastness diminishes, and expect the weld seam that the continuous nothing of a smooth is burnt; Except factors such as key process parameter control, protective gas, material processed, monitoring such as beam focus position, laser power, speed of welding, the quality control of welding anchor clamps butt welded seam has important role equally.Usually do not adopt the filling scolder during laser assembly solder, again because the laser beam focal diameter is very little, the splicing welding joint that weldment is spliced to form mutually to the influence of laser weld just greatly stitches more for a short time, and outward appearance is good more, and intensity is big more; Stitch when big, more serious groove shape weld seam occurs, intensity is also little, and the quality of therefore welding anchor clamps and laser weld just is closely related.

[specific embodiment]
Please join accompanying drawing 1 to Fig. 3, this embodiment discloses a kind of welding anchor clamps 100, is used for two or more than two weldment of clamping (not shown) to weld, and weldment is spliced to form splicing welding joint mutually.Weld jig 100 comprises the weld seam aligning parts 4 of supporting positioning element 1, the true edge parts 2 that are arranged at supporting positioning element 1 one sides and tack welding fitting of accepting weldment, the compacting part 3 that compresses weldment and adjustment splicing welding joint.Weld seam aligning parts 4 comprises locating shaft 41, rotates and promote the cylinder 42 of weldment and drive locating shaft 41 towards the straight-line actuator of weldment around locating shaft 41.
In a concrete embodiment, actuator is a cylinder 43, and cylinder is provided with two guide rods 431.Extend perpendicular to locating shaft 41 straight-line directions on locating shaft 41 edges, and cylinder 42 is sheathed on the locating shaft 41, makes that cylinder 42 and contacting of weldment are the line contact.The contact point of cylinder 42 and weldment is arranged on the weldment center line partially on the point of the certain distance in the outside.Weld seam aligning parts 4 also comprises the cover plate 44 of fixing locating shaft 41 and the connecting plate 45 of fixing cover plate 44, and connecting plate 45 is immobilizated in two guide rods 431.All with two guide rod 431 motions, cylinder 42 can rotate around locating shaft 41 simultaneously for cylinder 42, locating shaft 41, cover plate 44 and connecting plate 45.Cylinder 43 is provided with and limits two guide rod 431 strokes to set the fine setting block 46 of splicing welding joint standard clearance.
In a concrete embodiment; Weldment is a steel plate; Existing is that example is described whole welding anchor clamps 100 course of action with clamping two block plates, first steel plate and second steel plate: first, second steel plate all defines the toe that needs welding, the opposite side relative with toe and is positioned at the side of toe both sides: at first artificial toe with first steel plate (also be the benchmark steel plate) is near loose pin parts 7 and place and support on the positioning element 1, and another side that a side of pusher parts 6 promotions first steel plate makes first steel plate is near true edge parts 2; Adjustment component 8 promotes toe that the opposite side of first steel plate makes first steel plate accurately near loose pin parts 7, to guarantee the linearity of toe then; Compress first steel plate with compacting part 3 again, at this moment have good positioning fully as first steel plate of benchmark steel plate; Loose pin parts 7 are sunk, and a kind of concrete embodiment sinks loose pin parts 7 for utilizing the cylinder (not shown) that is connected with loose pin parts 7.Then second steel plate is positioned on the supporting positioning element 1, and makes the toe of the toe of second steel plate near first steel plate, another side that the side that pusher parts 6 promote second steel plate makes second steel plate is near true edge parts 2.
Then, use the connect splicing welding joint of formation of the toe of toe that weld seam aligning parts 4 adjusts first steel plate and second steel plate.Weld seam aligning parts 4 uses the cylinder rotatable 42 that is enclosed within on the locating shaft 41 cleverly, is connected on two guide rods 431 of cylinder 43 through cover plate 44 and connecting plate 45.After second steel plate was put supporting positioning element 1, the toe of first steel plate at this moment was in the reference position, but the toe of second steel plate has a segment distance or certain angle not on the reference position and with the reference position; The effect of cylinder 43 can make the toe of second steel plate near the reference position, but the motion of cylinder 43 has only rectilinear motion, can't carry out the adjustment of angle.When cylinder 42 touched the opposite side of second steel plate along with the motion of cylinder 43, contacting of opposite side and cylinder 42 was the line contact, and contact wire is their tangent line; If there is certain angle the toe of second steel plate and reference position, because contact point is arranged on the second steel plate center line partially on the point of the certain distance in the outside, and toe also is that a kind of line contacts with the reference position; And this contact wire position is not movable; Then along with the further motion of cylinder 43, under force couple role, cylinder 42 can and make the opposite side of second steel plate and the contact wire of cylinder 42 produce mobile around locating shaft 41 rotations; Make whole second steel plate rotate; Gradually rotate towards angled direction, be reduced into zero until angle, the toe of second steel plate approaches the reference position.Last under cylinder 43 straight-line effects and the gap of first steel plate be reduced to the minimum sandards gap that sets, second steel plate moves to the final position.The setting of this standard clearance and final position is to set the reasonable size of the fine setting block 46 of cylinder 43 (fine-tuning in case of necessity) through calculating first, second steel plate theoretical position.Final first, second steel plate gap reaches the gap that laser weld allows, and compresses second steel plate with compacting part 3 again, has promptly realized splicing welding joint closely this moment.Weld seam position naked eyes just can be observed splicing closely, and the postwelding weld seam is smoothly attractive in appearance, stretch through postwelding and test with bending that to detect intensity qualified.
Above-mentioned listed concrete implementation is nonrestrictive, and for a person skilled in the art, in not departing from the utility model scope, various improvement and the variation carried out all belong to the protection domain of the utility model.
