A kind of license support weld jigTechnical field
The utility model relates to fixture field.
Background technology
Along with the development of Chinese automobile cause, car exportation has become the grand strategy of Automobile Enterprises development, and the difference of Foreign Automobile laws and regulations and Chinese automobile rules causes outlet vehicle certain structures must change to meet external laws and regulations requirement.For example must there be a license support at Brazilian laws and regulations requirement back in-support carriage licence plate place, very large with domestic car difference, and car load, when outlet, weld license support at home, but license support structure is less, only has 52mm*12mm, welds more difficult on the basis of vehicle.
Present technology is the grip unit of license support 100 to be placed on to outside plate 200 bottoms then weld, due to the license support 100 less difficult location of structure, and back in-support carriage outside plate 200 blocks operator's sight line, cannot guarantee that solder joint is in the tram of license support 100.As shown in Figure 1, the solder joint of desirable license support 100 is positioned at a and b place.And in practical operation, easily there is riding side weld (being the c position that solder joint is arranged in Fig. 2), solder joint distortion, and to splash, the Welding Problems such as burr, solder joint mistake (being the d position that solder joint is arranged in Fig. 2), have a strong impact on welding quality.
Utility model content
The purpose of this utility model is to provide a kind of fixture that guarantees the correct welding of license support, and embodiment of the present utility model provides following technical scheme for this reason:
A license support weld jig, comprising: cylinder; Template; Pressure arm; Described pressure arm one end is provided with briquetting, the other end is connected with described cylinder pivotable, has the point being connected with described template pivotable between two ends, on described template, is provided with alignment pin, on described briquetting, be provided with magnet, described briquetting coordinates with described template the compression of carrying out license support
Preferably, on described template, be provided with the cushion block coordinating with described briquetting, on described cushion block, be provided with welding gun gathering sill.
Preferably, on described briquetting, be also provided with copper backing.
Preferably, described copper backing stretches out and extends to described welding gun gathering sill top from described briquetting below.
Preferably, on described template, be also provided with locating piece.
While utilizing fixture of the present utility model, the locating hole that utilizes alignment pin to pass on outside plate is realized location, then utilizes the magnet on briquetting to hold license support, cylinder promotes pressure arm action, license support is pressed on outside plate, thereby has avoided license support location inaccurate, guarantee that bond pad locations is correct.
Further, the welding gun gathering sill on cushion block can limit the movement locus of welding gun, has avoided welding gun to be welded to licence plate outside or edge because of motion.
Further; copper backing on briquetting can be protected license support; and the in the situation that of above copper backing extends to welding gun gathering sill; while utilizing electrode welding; one utmost point contacts with the outer intralamellar part of back in-support carriage by welding gun gathering sill guiding is rear; another utmost point contacts with copper backing, has avoided, in welding process, license support is produced to impression.
Accompanying drawing explanation
Next in connection with accompanying drawing, embodiment of the present utility model is described in further detail, wherein:
Fig. 1 is the desirable welding position schematic diagram of license support and outside plate;
Fig. 2 is the actual welding position view that prior art has been welded rear license stand and outside plate;
Fig. 3 is the license support weld jig stereogram of embodiment of the present utility model;
Fig. 4 is the license support weld jig front view of embodiment of the present utility model.
Description of symbols in upper figure: license support 100, back in-support carriage outside plate 200, cylinder 1, template 2, pressure arm 3, copper backing 4, welding gun gathering sill 5, alignment pin 6, briquetting 7, locating piece 8, the first pivotable tie point 9, the second pivotable tie point 10, cushion block 11.
The specific embodiment
With reference to figure 3, license support weld jig of the present utility model comprises cylinder 1, template 2 and pressure arm 3.Pressure arm 3 one end are provided with briquetting 7, and the other end relies on the first pivotable tie point 9 to be connected with cylinder 1 pivotable, between two ends, at the second pivotable tie point 10 places, is connected with template 2 pivotables.On template 2, be provided with cushion block 11 and alignment pin 6.On briquetting 7, be provided with magnet.When cylinder 1 piston rod shrinks, pressure arm 3 opens, and briquetting 7 is separated with cushion block 11, now back in-support carriage outside plate 200 is placed on fixture to the locating hole that alignment pin 6 passes on back in-support carriage outside plate 200, simultaneously locating piece 8 auxiliary positioning on template 2.Then license support 100 is adsorbed on briquetting 7, cylinder 1 piston rod stretches out, and pressure arm 3 presses down, and briquetting 7 compresses back in-support carriage outside plate 200 with cushion block 11, and license support 100 is pressed on back in-support carriage outside plate 200 simultaneously, has guaranteed that like this welding position is accurate.Or briquetting 7 directly coordinates compression license support 100 and does not need cushion block 11 with template 2.Simultaneously, for handled easily personnel still can weld in the situation that cannot seeing license support 100, on cushion block 11, be also provided with welding gun gathering sill 5.
With reference to figure 4; on briquetting 7, be also provided with copper backing 4; and copper backing 4 stretches out and extends to welding gun gathering sill 5 tops from briquetting 7 belows; copper backing 4 can be protected license support 100 so on the one hand; on the other hand when utilizing electrode welding; the arc welding gun head of one utmost point reaches the inner contact of back in-support carriage outside plate 200 by welding gun gathering sill 5 guiding, and the arc welding gun head of another utmost point contacts with copper backing 4, has avoided producing impression on license support 100.
Although the utility model is described in conjunction with above embodiment, but the utility model is not limited to above-described embodiment, and be only subject to the restriction of claim, those of ordinary skills can easily modify to it and change, but do not leave essence design of the present utility model and scope.
