Description
Technical field
The invention belongs to the positioning weldings of be welded body panel positioning field more particularly to a kind of sheet metal component and connection auxiliary
Structure.
Background technique
Connect auxiliary on generally by way of projection welding welding projection welding nut, then again by the connection auxiliary containing project-welding nut
It is welded on Metal Sheets for Body-manufacturing, the multiple connection auxiliaries of installation, therefore these connection auxiliary welding is generally required on Metal Sheets for Body-manufacturing
Position precision and Joint Strength all seem most important.In the prior art, as depicted in figs. 1 and 2, it is offered on sheet metal component A
Two spaced apart positioning round orifice 1,2, connect auxiliary B on two location holes in one be welded nut nut bore, separately
One be welded nut side positioning round orifice 4, due to the limitation of its plate face profile and size for connecting auxiliary B, connection
Spacing between nut bore 3 on auxiliary B and nut bore side positioning round orifice 4 is restricted, and is tightly connected in fixture locating clip auxiliary
After part B, the soldering turret space between two positioning pins can be made to become narrower, cause soldering turret into suitable weldering can not be adjusted after rifle
The problem of connecing posture perhaps soldering turret at all can not be into rifle to occur, which connects auxiliary and position well, difficult weld or can not weld at all
The common problem that is welded.
Summary of the invention
The sheet metal component and company that the object of the present invention is to provide a kind of to facilitate welding to operate in the case where ensuring accurate positioning
Connect the positioning welding structure of auxiliary.
To achieve the goals above, present invention employs following technical solutions:
A kind of sheet metal component and the positioning welding structure for connecting auxiliary, including the hole opened up respectively on connection auxiliary and sheet metal component
The first and third identical location hole of diameter, first and third location hole and master positioning pin implement location fit, offer on sheet metal component
4th location hole connects and offers the second location hole of nick shaped on auxiliary, the 4th location hole and second location hole indentation, there
Profile overlapping region and auxiliary positioning pin constitute location fit.
Beneficial effects of the present invention: in above-mentioned technical proposal, specifically when positioning, first by the first and third location hole and master positioning
Finger setting cooperates, then auxiliary positioning pin is placed in the profile overlapping region of the 4th location hole and second location hole indentation, there, connects in this way
The relative position connect between auxiliary and sheet metal component is just determined.The notch geometry of second location hole, it is ensured that main at this time,
Spacing between auxiliary positioning pin is greater than the spacing between two positioning pin in the prior art, thus seeks position and posture to welding gun
Adjustment leaves enough spaces, is difficult to reach the difficulty of position to be welded or posture of welding torch adjustment to realize welding gun.

Specific embodiment
Below with reference to Fig. 3 to Fig. 7, the present invention is described in further detail.
It is opened up respectively in a kind of sheet metal component and the positioning welding structure for connecting auxiliary, including connection auxiliary 10 and sheet metal component 30
Identical the first and third location hole 12,32 in aperture, in the actual operation process, first and third location hole 12,32 with it is main fixed
After position pin 22 implements location fit, the 4th location hole 31 is offered on sheet metal component 30, is connected and is offered nick shaped on auxiliary 10
Second location hole 11 is constituted with the profile overlapping region of 11 indentation, there of the 4th location hole 31 and second location hole and auxiliary positioning pin 21
Then auxiliary positioning pin 21 is placed in second to determine sheet metal component 30 and connect the relative position of auxiliary 10 by the mode of location fit
The indentation, there of location hole 11, the distance between such two positioning pin significantly increase, and it is straight that soldering turret distance can at least increase positioning pin
The half of diameter still has enough spaces to seek position and posture tune for welding gun after clamp sheet metal component 30 and connection auxiliary 10
It is whole, and do not change connection 10 size of auxiliary and matched 30 type face of sheet metal component.
The first positioning hole 12 of connection auxiliary 10 is overlapped with the threaded hole 131 of welded nut 13, first positioning hole 12 and spiral shell
The aperture of pit 131 coincide, and cooperates both in welding with master positioning pin 22 and realizes positioning, and connection auxiliary 10 and sheet metal component 30 weld
The first and third location hole 12,32 is overlapped to form through-hole with threaded hole 131 after connecing, and is with bolt or screw and its convenient for vehicle assembly
It is cooperatively connected.
There are three types of preferred schemes, as U-shaped breach, V-notch, arc to lack for the shape of second location hole 11 in the present invention
Mouthful.
There are two types of the preferred embodiments of 4th location hole 31, and one is circular hole, the second is strip-shaped hole and hole length direction
The extended line of center line is overlapped with the 32 hole heart of third location hole.
Any one of three kinds of schemes of above-mentioned second location hole 11 can in the two schemes of four location holes 31
Any one combination.
Need specification that auxiliary positioning pin 21 is first inserted in the 4th location hole 31 when the 4th location hole 31 is strip-shaped hole
In, when adjusting auxiliary positioning pin 21 makes it close to second location hole 11, as long as the shaft of auxiliary positioning pin 21 touches second location hole
11 edge profile simultaneously can limit connection auxiliary 10 and can not arbitrarily rotate, at this point, auxiliary positioning pin 21 and master positioning pin 22 it
Between spacing be just enough to ensure that the welding of welding gun operates.
In addition, in the structure that attached drawing 7b, 7c of the present invention provide two kinds of second location holes 11, meet auxiliary positioning pin 21 with
Under the premise of reserved welding spacing between master positioning pin 22, the size that can also reduce connection auxiliary 10 uses material to reduce
Amount, is conducive to save the cost and can reduce car body weight.
