Description
Technical Field
The utility model relates to a car U-shaped support spare 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.
Disclosure of Invention
The to-be-solved technical problem of the utility model is: aim at provides a car U-shaped support spare 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, reduce cost.
The utility model provides a technical scheme that its technical problem adopted is: the utility model provides a car U-shaped support spare nut welding is with location frock, including base and positioning bolt, positioning bolt's bottom have with positioning bolt vertically plane backing plate, the plane backing plate is fixed to be set up on the base, the positioning bolt lower extreme is opened has the wedge to lead to the groove and is furnished with the wedge inserted block that corresponds, positioning bolt and two coaxial mounting hole clearance fit of required welding process's U-shaped support spare to with required welded mounting nut phase-match.
When the positioning tool for welding the automobile U-shaped bracket part nut is used, the positioning bolt is sleeved in the upper mounting hole and the lower mounting hole of the U-shaped bracket part, then the wedge-shaped inserting block is inserted into the wedge-shaped through groove of the positioning bolt and is pushed tightly, and the wedge-shaped inserting block generates downward pressure on the lower part of the U-shaped bracket part, so that the lower part of the U-shaped bracket part is clamped by the wedge-shaped inserting block and the plane base plate, and the positioning of the U-shaped bracket part is kept; then the mounting nut is screwed in from the head end of the positioning bolt until the mounting nut is attached to the U-shaped bracket part, and welding can be carried out. After welding, the wedge-shaped insert block is pulled out to release the clamping of the U-shaped support part, the mounting nut is screwed in the opposite direction or the U-shaped support part is rotated (the mounting nut and the U-shaped support part are welded into a whole at the moment), and the U-shaped support part can be taken down from the positioning bolt when the mounting nut is separated from the positioning bolt.
In order to prevent welding slag from splashing on the bolt head or the upper surface of the mounting nut during welding, the positioning tool for welding the automobile U-shaped bracket part nut is also provided with a bolt protective cap matched with the head end of the positioning bolt. And during welding, covering a bolt protective cap at the head end of the positioning bolt.
In order to facilitate the operation of workers on the wedge-shaped insertion block, the tail part of the wedge-shaped insertion block is provided with a handle.
The utility model has the advantages that: this location frock is used in welding of car U-shaped support spare and mounting nut, and it can effectively guarantee the axiality of welding back mounting nut and U-shaped support spare mounting hole to ensure welding precision, the screw that can prevent welding slag entering mounting nut when welding simultaneously again from causing the destruction, therefore makes product welding process qualification rate and welding quality improve greatly, has reduced the processing cost. The positioning tool for welding the U-shaped bracket part nut of the automobile is simple in structure, easy to manufacture and convenient to operate and use.
Drawings
The present invention will be further explained with reference to the drawings and examples.
FIG. 1 is a schematic structural view of the present invention (including the U-shaped bracket member to be welded and the mounting nut; with parts shown in cross-section); fig. 2 is a front view structural diagram (dotted line represents perspective) of the positioning bolt of the present invention; fig. 3 is a left side view structure diagram of the positioning bolt of the present invention.
In the figure: 1. the base 2, the positioning bolt 2-1, the wedge-shaped through groove 3, the plane backing plate 4, the wedge-shaped inserting block 4-1, the handle 5, the U-shaped support part 6, the mounting nut 7 and the bolt protective cap.
Detailed Description
The utility model provides a car U-shaped support spare nut welding is with location frock, as shown in figure 1, figure 2 and figure 3, it includes base 1 and positioning bolt 2, positioning bolt 2's bottom has with positioning bolt 2 vertically plane backing plate 3, plane backing plate 3 is fixed to be set up on base 1, positioning bolt 2 lower extreme is opened has wedge to lead to groove 2-1 and is furnished with corresponding wedge inserted block 4, positioning bolt 2 and two coaxial mounting hole clearance fit of the U-shaped support spare 5 of required welding process, and with required welded mounting nut 6 phase-match. In addition, a bolt protective cap 7 matched with the head end of the positioning bolt 2 is also arranged to prevent welding slag from splashing on the bolt head or the upper surface of the mounting nut during welding. The tail part of the wedge-shaped insertion block 4 is provided with a handle 4-1 so as to facilitate the operation of workers on the wedge-shaped insertion block.
When the positioning tool for welding the automobile U-shaped bracket part nut is used, the positioning bolt 2 is sleeved in the upper mounting hole and the lower mounting hole of the U-shaped bracket part 5, then the wedge-shaped inserting block 4 is inserted into the wedge-shaped through groove 2-1 of the positioning bolt 2 and is pushed tightly, and the wedge-shaped inserting block 4 generates downward pressure on the lower part of the U-shaped bracket part 5, so that the lower part of the U-shaped bracket part 5 is clamped by the wedge-shaped inserting block 4 and the plane base plate 3, and the positioning of the U-shaped bracket part 5 is kept; then, the mounting nut 6 is screwed in from the head end of the positioning bolt 2 until the mounting nut 6 is attached to the U-shaped bracket part 5, and after the bolt protective cap 7 is covered, welding can be carried out. After welding, the wedge-shaped insert block 4 is pulled out to release the clamping of the U-shaped support part 5, the bolt protective cap 7 is taken down, the mounting nut 6 is screwed in the opposite direction or the U-shaped support part 5 is rotated (at the moment, the mounting nut 6 and the U-shaped support part 5 are welded into a whole), and the U-shaped support part 5 can be taken down from the positioning bolt 2 when the mounting nut 6 is separated from the positioning bolt 2.
