Summary of the invention
The purpose of this utility model is the deficiency existing for prior art, provides a kind of general assembly type automobile front upper member positioning fixture, and it is registration not only, and can also reuse, cost-saving.
The technical solution of the utility model is as follows:
Upper member positioning fixture before a kind of general assembly type automobile, comprises the first backstay, the second backstay being connected with the first backstay, wherein, described the first backstay is down " U " shape, by one short vertical section a, flat segments and one long vertical section connect and compose successively; Described the second backstay is " ┓ " shape, is connected and composed by a horizontal segment and a vertical section, and the end of described the second backstay horizontal segment is fixedly connected with the long vertically middle part of section of the first backstay.The first backstay and the second backstay pass through CO
2protection weldering is welded together, and angle and vehicle headlight bracket locating hole line are consistent.
Further, the length of described the first backstay vertically lower end of section is provided with chamfering, as the first alignment pin, to facilitate the dismounting of positioning fixture; The lower end of short vertical section of described the first backstay is provided with chamfering, as the second alignment pin, to facilitate the dismounting of positioning fixture; The lower end of vertical section of described the second backstay is provided with chamfering, as the 3rd alignment pin, to facilitate the dismounting of positioning fixture.
Further, the length of described the first backstay vertically bottom of section is provided with the first magnetic locating piece, and the bottom of vertical section of described the second backstay is provided with the second magnetic locating piece.
Further, below described the first magnetic locating piece with described the second magnetic locating piece below in same level.
Further, the angle α that the center line of the center line of described the first backstay flat segments and described the second backstay horizontal segment is handed at horizontal plane upslide shade is an obtuse angle.
Further, described obtuse angle alpha is 124 °.
Further, described the first backstay and described the second backstay are round steel member, and material can be selected 45 steel.
Further, described the first backstay and described the second backstay are round steel member, and material can be selected 45 steel.
Compared to the prior art the utility model has the following advantages: the utility model not only can be reused, and easy to operate, and registration has been saved cost; Also prevent that alignment pin welding is rear exposed in the outside of front upper member simultaneously, ensured the attractive in appearance of vehicle body.

Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail:
Referring to upper member positioning fixture before a kind of general assembly type automobile shown in Fig. 1 to Fig. 3, comprise the first backstay 11, the second backstay 12 being connected with the first backstay, described the first backstay 11 is down " U " shape, is connected and composed successively by one short vertical section a, flat segments and a long vertically section; Described the second backstay 12 is " ┓ " shape, is connected and composed by a horizontal segment and a vertical section, and the end of described the second backstay 12 horizontal segments is fixedly connected with the first long vertically middle part of section of backstay 11.
The length of described the first backstay 11 vertically lower end of section is provided with chamfering, as the first alignment pin 15; The lower end of short vertical section of described the first backstay 11 is provided with chamfering, as the second alignment pin 16; The lower end of vertical section of described the second backstay 12 is provided with chamfering, as the 3rd alignment pin 17.
The length of described the first backstay 11 vertically bottom of section is provided with the first magnetic locating piece 13, and the bottom of vertical section of described the second backstay 12 is provided with the second magnetic locating piece 14.
