Problems solved by technology

[0002] The existing automobile tailgate hinge bolts are mostly fixed on the bracket by welding or knurling. Due to the change of resistance and current, the connection is not firm enough, and the bolts often fall off. Under the impact, there is a phenomenon of falling off and spinning, and the way of welding and knurling is easy to make rainwater leak into the car box from the gap between the bracket and the bolt

Embodiment 1

[0027] Figure 1 to Figure 6 A waterproof and anti-rotation tailgate hinge according to an embodiment of the present invention is schematically shown.

[0028] refer to Figure 1 ~ Figure 3 , The anti-rotation bolt 1 includes a nut 11 , an assembly section 12 , a threaded rod 13 and a nut guide rod 15 formed integrally. The assembly section 12, the threaded rod 13 and the nut guide rod 15 jointly form the screw rod of the anti-rotation bolt. One end of the assembly section 12 is connected with the nut 11 , the other end of the assembly section 12 is connected with one end of the threaded rod 13 , and the nut guide rod 15 is connected with the other end of the threaded rod 13 .

[0029] An anti-rotation 121 is provided on the peripheral surface of the assembly section 12 . The anti-rotation position 121 can be processed into a planar structure, and the planar anti-rotation position can be processed easily. The anti-rotation position 121 can also be processed into other shap...

Embodiment 2

[0037] A method for riveting a waterproof and anti-rotation tailgate hinge, assembling the anti-rotation bolt 1 and bracket 2 in Embodiment 1, comprising the following steps:

[0038] 1) The through hole 21 of the anti-rotation bolt 1 and the bracket 2 is made into a flat shape or other non-circular shape to prevent rotation;

[0039] 2) The assembly section 12 of the anti-rotation bolt 1 is processed to be 0.4-0.6mm longer than the length of the through hole 21 of the bracket 2, preferably 0.5mm. And make the anti-rotation bolt 1 and the through hole 21 of the bracket 2 form a clearance fit of about 0.1mm;

[0040] 3) Set a chamfer 16 at the connection between the nut 11 and the assembly section 12, and set a section of threadless nut guide rod 15 whose diameter is smaller than the inner diameter of the nut at the tail of the bolt. The diameter of the nut guide rod 15 is 0.2mm smaller than the inner diameter of the nut , play a guiding role during assembly to prevent teeth s...

Abstract

The invention discloses a waterproof and anti-rotation tail door hinge and a riveting method. The waterproof and anti-rotation tail door hinge comprises an anti-rotation bolt. The anti-rotation bolt comprises a nut, an assembling section and a threaded rod. One end of the assembling section is connected with the nut, the other end of the assembling section is connected with one end of the threaded rod, and the assembling section is provided with an anti-rotation position. The tail door hinge riveting method comprises the steps that firstly, the anti-rotation bolt and a through hole of a support are made into a flat shape or other non-circle shapes so that rotation can be prevented; secondly, the length of the assembling section of the anti-rotation bolt is larger than that of the through hole of the support, and the anti-rotation bolt and the through hole of the support are in clearance fit; thirdly, a chamfer is arranged at the connecting position of the nut and the assembling section, and a section of toothless nut guiding rod with the diameter smaller than the inner diameter of the nut is arranged at the tail of the bolt; and fourthly, the assembling section of the anti-rotation bolt is compressed in a punching manner, the assembling section of the anti-rotation bolt becomes thick to fill in the through hole of the support, and an inverted buckle protruding position is formed on the end face. The effects of leakage prevention, rotation prevention, disengaging prevention and tooth sweeping prevention can be achieved.

Description

technical field [0001] The invention relates to the field of automobile hinge manufacturing, in particular to a waterproof and anti-rotation tailgate hinge and a riveting method. Background technique [0002] The existing automobile tailgate hinge bolts are mostly fixed on the bracket by welding or knurling. Due to the change of resistance and current, the connection is not firm enough, and the bolts often fall off. Under the impact, there are many phenomena of falling off and spinning, and the way of butt welding and knurling is easy to make rainwater leak into the car box from the gap between the bracket and the bolt. Contents of the invention [0003] The invention provides a waterproof and anti-rotation tailgate hinge and a riveting method, which can make the automobile door hinge firmly connected with the vehicle body, and has the advantages of anti-leakage, anti-rotation, anti-falling, anti-sweeping and the like. [0004] According to one aspect of the present inven...
