Detailed Description

As shown in fig. 1-4, the utility model provides a technical solution: the utility model provides a can realize direction and locate function's T type welded nut mounting structure, includes T type welded nut 7, automobile body panel beating one 5, automobile body panel beating two 6 and preceding bracket 8, passes through T type welded nut 7 fixed connection between automobile body panel beating one 5, automobile body panel beating two 6 and the preceding bracket 8.

T type welded nut 7 includes welded flange 1 and round pin post ectosome 4, the inside cavity setting of round pin post ectosome 4, and inside is provided with the screw thread, welded flange 1 one side and 4 one end welding of round pin post ectosome, V type groove 3 has been seted up to 4 one ends of round pin post ectosome, 4 outer walls of round pin post ectosome are provided with angle location plane 2,

V type groove

3 and 2 parallel arrangement of angle location plane, be provided with spacing plane 9 on the front bracket 8, the quantity of angle location plane 2 is two, 2 symmetric distribution of two angle location planes, angle location plane 2 and spacing plane 9 parallel arrangement.

And the first vehicle body metal plate 5, the second vehicle body metal plate 6 and the front bracket 8 are fastened and connected through a T-shaped welding nut 7. In a welding workshop, the T-shaped welding nut 7 is accurately positioned and welded with the second car body metal plate 6 through the matching of the clamp and the V-shaped groove 3; the first automobile body metal plate 5 and the second automobile body metal plate 6 are welded in sequence, compared with the traditional metal plate welding method through complete fitting, the acceptable range of errors between the first automobile body metal plate 5 and the second automobile body metal plate 6 is enlarged under the matching of the T-shaped welding nut 7, and the spacing distance is designed between the first automobile body metal plate 5 and the second automobile body metal plate 6, so that the relative positions of the first automobile body metal plate 5 and the second automobile body metal plate 6 can be finely adjusted during welding, the welding difficulty is reduced, and the welding precision is improved; the front bracket 8 reaches the attaching state of the limiting plane 9 through the angle positioning plane 2 of the T-shaped welding nut 7, and the accurate positioning between the front bracket 8 and the body in white is realized.
