Description
Technical field
The utility model belongs to riveter line group to technical field, relates generally to a kind of positioning tool of bogie curb girder, is applicable to the curb girder secondary assembly welding operation in the bogie production.
Background technology
The bogie curb girder constitutes by upper cover plate, lower cover with at the polylith riser between the cover plate up and down; When manufacturing the bogie curb girder; With the bogie curb girder up and down cover plate and riser through the right mode assembly welding of line group; This traditional work pattern is inefficiency not only; And relative dimensions is difficult to guarantee that can't satisfy the requirement of drawing and technology: the curb girder longitudinal size is 3440mm, tolerance+4mm; The lower cover linearity requires to be 3mm, lower cover two ends plane parallel degree 3mm.If group to the time, cover plate is not accurately located according to drawing requirement with riser up and down, just can have influence on the quality of whole curb girder, assembles thereby have influence on annex nearly all on the framework, influences the quality of final products greatly.
Summary of the invention
The purpose of the utility model is the positioning tool that proposes a kind of bogie curb girder, make its can avoid the line group to the time error that produces, but high efficiency, high-quality riser and upper and lower cover plate are organized together accurately, enhance productivity.
The technical scheme that its invention task of the utility model completion is taked is:
A kind of positioning tool of bogie curb girder, described positioning tool mainly comprises base, portal frame and puller bolt; Described base is middle ship type structure to lower recess; Described base is provided with a plurality of portal frames along the center symmetry; Described portal frame is made up of location-plate, inverted L shape connecting lever and leading screw; Described inverted L shape connecting lever is two; One end of two inverted L shape connecting levers is connected a side of base; The other end of two inverted L shape connecting levers is connected between two inverted L shape connecting levers through the upper end of bearing pin with location-plate, and the lower end that is fixed on the location-plate on the base in order to the lower cover with curb girder is connected the opposite side of base; Described screw mandrel is two, wherein is connected on the transverse arm of inverted L shape connecting lever in order to the screw mandrel I with curb girder upper cover plate location, and the screw mandrel II of locating in order to the curb girder riser is connected on the perpendicular arm of inverted L shape connecting lever; Described puller bolt is two that are positioned on the base, and the spacing between two puller bolts equates with the longitudinal length of bogie curb girder.
Above-mentioned positioning tool is placed on the lower cover of curb girder on the base plane of machined in use, simultaneously with the location-plate location of portal frame; To organize the outside that good riser is placed on the perpendicular arm of inverted L shape connecting lever then, and the lower end of riser will be placed on the lower cover, locate by the screw mandrel II; At last upper cover plate is placed on the riser top, by the screw mandrel I location of inverted L shape connecting lever; With puller bolt fastening after, adopt positioner to carry out spot welding.
The positioning tool of a kind of bogie curb girder that the utility model proposes; Through being fixed on the base, lower cover locatees; Avoided the line group to the time error that produces, but high efficiency, high-quality riser and cover plate are up and down organized together accurately, improved production efficiency greatly; Positioner is used for changing the welding position, realizes changing flat fillet weld into fillet welding in the flat position.
