Description
Technical field
The utility model relates to a kind of anchor clamps, especially for the online weld jig of automobile roll-in near closed hollow ring bumper laser, belongs to the Machining Technology field.
Background technology
Roll-in processing is one of main method of making at present by bumper, and the online welding of roll-in bumper laser is a kind of advanced person's a solder technology, and laser weld requires soldered workpiece solder side smooth, and spacing is suitable evenly.For the online welding of bumper laser with near closed hollow ring, it is just very difficult to satisfy top said specification requirement.Its reason is as follows: 1,, processes front bumper when generally adopting high-strength steel sheet, and difficult forming, wave often appears in solder side in the actual roll-in production process; 2,, thereby make the phenomenon that not prison welding is solid even do not weld because die cavity is a sealing hollow, and two soldered limits are easy to occur the staggered phenomenon of height.Existing Laser Welding anchor clamps generally adopt the method in roller parcel cross section, promptly with one or more groups roller the roll-in bar shaped are wrapped up, and make it that the gap, commissure can stable and uniform when welding.But this method then can't satisfy welding requirements for the bumper of enclosed cavity, its reason is: it is that the thin cavity of wall is big that this bumper cuts the type characteristics, if support cavity anchor clamps then can not occur and can't filter out the wave that roll-in produces, cause the laser instrument tracking accuracy to descend; In addition, weld the staggered phenomenon of height on two limits occurs and can not eliminate by adjusting anchor clamps, and welding quality is difficult for guaranteeing.
The utility model content
The utility model is used to solve the defective of above-mentioned prior art and a kind of online weld jig of roll-in near closed hollow ring bumper laser that guarantees that the weld slit is uniform and stable, welding quality is good is provided.
The alleged problem of the utility model solves by the following technical programs:
The online weld jig of a kind of roll-in near closed hollow ring bumper laser, comprise in the formation that adjacent and structure is provided with identical trace bit and welding position two parts, special feature is: comprise bottom roller in the formation of described trace bit or welding position part, the side wheel, top board, the pressing plate mount pad, fuse and pull bar, described bottom roller is positioned at the processed bumper bottom, support processed bumper, described side wheel is symmetricly set on the processed bumper both sides, side is taken turns circumferential profile and processed bumper dual-side outline, described fuse is positioned at the enclosed shape chamber of processed bumper, described top board presses on processed bumper top, the affixed pressing plate mount pad of top board, top board is consistent with gap and processed bumper wall thickness dimension between the fuse upper surface, and the top board middle part is provided with welding hole.
The online weld jig of above-mentioned roll-in near closed hollow ring bumper laser, both sides cincture wheel shaft is passed in described pressing plate mount pad both sides, is provided with two positioning nuts on the wheel shaft of each side wheel, and the positioning nut lays respectively at the upper and lower part of pressing plate holder.
The online weld jig of above-mentioned roll-in near closed hollow ring bumper laser, described fuse middle part is symmetrical arranged tie rod hole, and two pull bars are by passing in this hole, and nut is fixed fuse and pull bar, and pull bar one end is fixed by the pull bar holder.
The utility model improves at the bumper processing problems that the existing online weld jig of automobile roll-in bumper laser is unsuitable near closed hollow ring, the structure that described anchor clamps adopt four sides parcel, inner chamber to fill makes gap, soldered bumper commissure keep uniform and stable, and on bumper, adopt wear-resisting pressing plate to replace habitual roller, promptly replace the line contact with the face contact, increase the constraint area greatly, thereby can effectively filter out the wave that the front roll-in produces.Through above-mentioned improvement, the utility model has successfully solved the online welding of roll-in near closed hollow ring bumper laser, be prone to the difficult problem that not prison welding is solid, the roll extrusion wave is difficult for filtration, have characteristics such as simple and compact for structure, that the weld slit is uniform and stable, and welding quality is good.
Description of drawings
Fig. 1 is the utility model structural representation;
Fig. 2 is that the A of Fig. 1 is to view.
Label is expressed as follows in the accompanying drawing: 1. pull bar holder; 2. pull bar; 3. processed bumper; 4. top board; 4-1. welding hole; 5. fuse; 6. pressing plate mount pad; 7. nut; 8. bottom roller; 9. side is taken turns; 10. positioning nut; 11 trace bits; 12. welding position; 13 sides wheel wheel shaft; 14. roll extrusion wheels.
The specific embodiment
Referring to Fig. 1, during constituting, the utility model comprises roll extrusion wheels 14 and trace bit 11, welding position 12, described trace bit, welding position is adjacent and structure is provided with identical.
Referring to Fig. 1, Fig. 2, comprise bottom roller 8, side wheel 9, top board 4, pressing plate mount pad 6, fuse 5 and pull bar 2 in the formation of trace bit or welding position.As seen from Figure 2, side wheel 9, bottom roller 8, top board 4 is with the periphery parcel of processed bumper 3, and fuse 5 is supported in the cavity of processed bumper.The effect of above-mentioned each parts is as follows: both sides cincture 9 circumferential profile and processed bumper dual-side outline, to prevent the processed bumper opening; Bottom roller 8 supports processed bumper; The gap just is that the material of processed bumper is thick between fuse 5 and the top board 4.This structure makes the left and right directions of processed bumper by 9 constraints of side wheel, above-below direction is by top board and fuse 5 constraints, and is whole by bottom roller 8 supports, like this, phenomenons such as the wave that processed bumper produces in earlier stage, opening are revised under constraint, thereby have guaranteed welding quality.
Still referring to Fig. 1, Fig. 2, the utility model substitutes original roller with the top board 4 of high-abrasive material preparation, the benefit of doing like this is the line contact that has replaced roller with the face contact, with fuse 5 actings in conjunction of inner chamber under, the constraint area increases, make that the wave that produces before the processed bumper welding is effectively filtered out, solder side is played the effect of a shaping, the top board middle part is provided with welding hole 4-1.The fuse 5 usefulness pull bars 2 that are positioned at the processed bumper inner chamber wear, and fix the position with nut 7, make it corresponding tracing positional and welding position respectively, and pull bar one end is fixing by pull bar holder 1.After in the cavity of processed bumper fuse being set, the inner chamber of hollow is tamped by fuse on above-below direction, the top phenomenon that indent can not occur of welding.Top board 4 is affixed by screw and pressing plate mount pad 6, both sides cincture wheel shaft 13 is passed in pressing plate mount pad 6 both sides, on the wheel shaft of each side wheel, be provided with two positioning nuts 10, the positioning nut lays respectively at the upper and lower part of pressing plate holder, turn positioning nut promptly can be adjusted the upper-lower position of pressing plate mount pad 6, thereby guarantees that the gap between top board and the fuse 5 is the wall thickness of processed bumper.
