Description
Technical Field
The utility model relates to a U-shaped leg joint nut welding is with location frock.
Background
A plurality of U-shaped supports are arranged in the automobile support part, and the supports can be assembled only by welding mounting nuts at mounting holes of the supports. When the mounting nut is welded on the U-shaped bracket of the automobile, due to the particularity of the shape of the U-shaped bracket, the positioning stability of the existing fixture device on the U-shaped bracket and the mounting nut is poor, and in addition, the welding precision is often low due to micro-deformation factors caused by welding, and the coaxiality of a screw hole of the mounting nut and two coaxial mounting holes of the U-shaped bracket is poor; in addition, welding slag is easy to splash into the screw hole of the mounting nut during welding to cause damage to the screw hole. These conditions all lead to a reduction in the processing yield of the product and an increase in the processing cost.
SUMMERY OF THE UTILITY MODEL
The to-be-solved technical problem of the utility model is: aim at provides a U-shaped support mounting nut welding is with location frock for improve the welding precision and prevent that the welding slag from destroying the nut hole, thereby improve product welding process qualification rate and product quality.
The utility model provides a technical scheme that its technical problem adopted is: the utility model provides a U-shaped leg-mounting nut welding is with location frock, which comprises a base, vertical division has the screw and is equipped with positioning bolt in the screw in the base, positioning bolt's upper and lower both ends all stretch out the base, and positioning bolt's lower bandeau has the head of screwing, the fixed clamp lamella bolt that has worn of level in the base, clamp lamella and lock nut all wear to be equipped with at the both ends of clamp lamella bolt, the clamp lamella comprises clamping piece and bolt cover an organic whole, the lower surface of clamping piece is flat to the upper surface of base, bolt cover is on clamp lamella bolt, lock nut has the swing handle, positioning bolt's upper end is furnished with the nut cap.
When the positioning tool for welding the U-shaped support mounting nut is used, the upper mounting hole and the lower mounting hole of the U-shaped support are sleeved into the positioning bolt, the U-shaped support is arranged on the base, the locking nuts at the two ends of the clamping flap bolt are screwed to enable the clamping piece of the clamping flap to clamp the lower part of the U-shaped support, so that the U-shaped support is positioned on the base, the mounting nut is screwed in from the upper end of the positioning bolt to the upper part of the mounting nut attached to the U-shaped support, and the nut protective cap is sleeved at the upper end of the positioning bolt to shield the inner hole of the mounting nut, so that welding can be carried out. And after welding, screwing the screwing head of the lower head of the positioning bolt so as to separate the mounting nut from the positioning bolt, then unscrewing the locking nut, and removing the nut protective cap, so that the U-shaped support welded with the mounting nut can be taken down.
The utility model has the advantages that: this U-shaped leg mount nut welding is with location frock simple structure, easy manufacturing, operation convenient to use, it can effectively guarantee the axiality of welding back mounting nut and U-shaped leg mount hole, ensures the welding precision, can prevent again simultaneously that the welding slag from getting into mounting nut's screw and causing the destruction during welding to make product welding processing qualification rate and welding quality improve greatly.
