A kind of auto pedal weld jig
The invention belongs to the technical field of automobile manufacturing process.Specifically, the present invention relates to a kind of auto pedal weld jig.
In the prior art, the weld jig of auto pedal is can not the structure of mode, and its shortcoming is:
1, to manufacture difficulty large for fixture, fixture manufacture and debugging production efficiency low;
2, corresponding adjustment can not be done according to Site Welding situation, welding production difficult quality guarantee in actual welding.
Summary of the invention
The invention provides a kind of auto pedal weld jig, its objective is quick, the convenient adjustment realizing fixture.
To achieve these goals, the technical scheme that the present invention takes is:
Auto pedal weld jig provided by the present invention, comprises clamp bottom board, and described weld jig is provided with adjustment block and adjustment pad; Described adjustment block is provided with link bolt hole and dowel hole, and described adjustment pad is provided with the slot corresponding with dowel hole position to described link bolt hole.
Described adjustment block is " L " shape.
The quantity of described adjustment block is multiple, and is fixedly connected on described clamp bottom board.
Specifically, the quantity of described adjustment block 3 is three, and three directional spreding of spatially rectangular coordinate system.
Described adjustment block is connected to each other, and by adjustment pad pad between described adjustment block, described adjustment pad is that one or more pieces are superimposed.
The thickness of described adjustment pad is 3mm, and its variation is within ± 3%.
The present invention adopts technique scheme, can according to Site Welding situation, Rapid adjustment fixture; Can standardization be realized, be applicable to the manufacturing of multiple weld jig of the same type; Material consumption is few, and save material cost; Improve the welding quality of product; Be convenient to maintenance, interchangeability is good; Handsome in appearance, make outward appearance more good-looking.

Detailed description of the invention
Contrast accompanying drawing below, by the description to embodiment, the specific embodiment of the present invention is described in further detail, have more complete, accurate and deep understanding to help those skilled in the art to inventive concept of the present invention, technical scheme.
Structure of the present invention as shown in Figure 1, is a kind of auto pedal weld jig, comprises clamp bottom board 1.For carrying out welding processing to auto pedal 2.
In order to solve prior art Problems existing and overcome its defect, realize the goal of the invention of quick, the convenient adjustment of fixture, the technical scheme that the present invention takes is:
As shown in Figures 1 to 4, described weld jig is provided with adjustment block 3 and adjustment pad 4; Described adjustment block 3 is provided with link bolt hole 5 and dowel hole 6, and described adjustment pad 4 is provided with the slot 7 corresponding with dowel hole 6 position to described link bolt hole 5.
The present invention is adjusted by adjustment block 3, or by the mode of adjustment pad 4 between increase and decrease adjustment block 3, realizes the adjustment of fixture in space X, Y, Z tri-directions, thus realizes the convenience, adjustable of fixture.
The structure of described adjustment block 3 is " L " shape.This shape can realize being connected and fixed in a direction, and another direction is connected with other adjustment block, and can regulate its spacing distance by adjustment pad; Or workpiece is positioned.
Adjustment block 3 be connected and fixed mode:
The quantity of described adjustment block 3 is multiple, and is fixedly connected on described clamp bottom board 1.
The quantity of described adjustment block 3 is three, and three directional spreding of spatially rectangular coordinate system.
Described adjustment block 3 is connected to each other, and pads between described adjustment block 3 by adjustment pad 4, and described adjustment pad 4 is that one or more pieces are superimposed.
The technical requirement of adjustment pad 4:
The thickness of described adjustment pad 4 is 3mm, and its variation is within ± 3%.
1, adjusting the design thickness of pad is 3mm, allows thickness tolerance of floating to be 3%p1;
2, fixture regulation block pad is: 2 × 0.5mm+1mm × 2;
Clamp locating pin pad is: 0.2mm × 1+0.3mm × 1+0.5mm × 1+1mm × 2.
Adjustment block 3 can according to the fixed several specification of actual conditions, and adjustment block 3 realizes mutual fixing by two alignment pins and a bolt.
Above by reference to the accompanying drawings to invention has been exemplary description; obvious specific implementation of the present invention is not subject to the restrictions described above; as long as have employed the improvement of the various unsubstantialities that method of the present invention is conceived and technical scheme is carried out; or design of the present invention and technical scheme directly applied to other occasion, all within protection scope of the present invention without to improve.
