The technical scheme that its technical problem that solves the utility model adopts is: a kind of arc weldment locating piece, locating piece is provided with hyperboloid and some fastening screw keyholes, described locating piece is provided with at least three bi-curved locating holes of processing, locating hole and hyperboloid be arranged in parallel, the axis antarafacial of locating hole.Locating piece can be fixed on the weld jig by the fastening screw keyhole, then the arc weldment be supported the location; At least three locating holes, and the axis antarafacial of locating hole, such setting are to the machining benchmark that provides of hyperboloid processing on the locating piece, and locating hole also can be used as the adjustment benchmark of locating piece when the arc weldment of location simultaneously.
As a kind of preferred version of such scheme, the fastening screw keyhole laterally or vertically runs through locating piece, and such being provided with conveniently is fixed in locating piece on the weld jig.
As a kind of preferred version of such scheme, locating piece is that square, square locating piece is simple in structure, be convenient to processing, simultaneously also be convenient to locating piece is fixed on the soldering cramping apparatus, locating piece also can be polygonal shapes such as pentagon, hexagon, and this can process more hyperboloid on locating piece.
As a kind of preferred version of such scheme, fastening screw keyhole one end is positioned on the hyperboloid, is arranged so that like this when locating piece is fixed on the soldering cramping apparatus, and the hyperboloid on the locating piece can better be fitted and be supported the arc weldment.
As a kind of preferred version of such scheme, the locating piece surface at fastening screw keyhole other end place is provided with some dowel holes, and dowel hole is parallel to the setting of fastening screw keyhole.Dowel hole can make locating piece fixing more firm on soldering cramping apparatus, guarantees positioning accuracy, and preferably two of dowel holes are symmetricly set on the both sides of fastening screw keyhole.
A kind of preferred version as such scheme, the locating piece surface at fastening screw keyhole other end place is provided with rectangular recess, rectangular recess can replace the effect of dowel hole, make locating piece fixing more firm on soldering cramping apparatus, the width of rectangular recess preferably with soldering cramping apparatus on the position of installation locating piece match.
As a kind of preferred version of such scheme, hyperboloid has one or several.The a plurality of hyperboloids of processing on locating piece, each hyperboloid is set to different radians, improved the applicability of locating piece like this, in the face of different arc weldment the time, can select for use suitable hyperboloid to position support, reduce the setting of different model locating piece, saved cost, the fastening screw keyhole of the different fixing direction that matches with a plurality of hyperboloids need be set simultaneously, to satisfy different location requirement.
The beneficial effects of the utility model are: by locating hole is set on the locating piece, can on locating piece, accurately process hyperboloid, simultaneously when locating piece supports the location, position by the detection and location hole, just can judge that whether locating piece is to having the accurate support location of arcwall face bodywork parts, the location benchmark is provided for bodywork parts, has improved the precision and the quality of body in white welding with arcwall face.
