Description

Prevent nut of electrophoresis pocket liquid and pocket gas

Technical Field

The utility model relates to a nut structure of suspension support among car sub vehicle frame assembly, especially a prevent nut of electrophoresis pocket liquid and pocket gas.

Background

The prior art is a common hexagonal flange nut, which usually adopts a cold heading process, and is used as a sub-part of an auxiliary frame assembly or other welding part assemblies and connected with the assembly through welding. FIG. 1 is a schematic view of an auxiliary frame assembly, which employs a stamping and welding process, wherein a suspension bracket 2 is vertically suspended during electrophoresis, and the arrow direction is upward; fig. 3 is a partial enlarged view of the suspension bracket, and fig. 2 shows that the nut 1' is a common hexagonal flange nut, the lower surface is a plane, and the nut is completely attached to the suspension bracket after welding. Another design may be adopted, as shown in fig. 4, the hexagonal flange nut is welded to another hole site of the suspension bracket.

During the electrophoresis of current scheme sub vehicle frame assembly, can take place pocket liquid or pocket gas around the hexagonal flange face nut. If the scheme of fig. 3 is adopted, electrophoretic fluid (shown in fig. 5) can be accumulated in the concave part around the nut, so that the quality of a paint film is poor; if the scheme of fig. 4 is adopted, air can be accumulated in the concave part on the periphery of the nut (shown in fig. 6), so that the area cannot be contacted with the electrophoretic liquid, and no paint film exists at the position after electrophoresis. And because near hexagonal flange face nut, the suspension support does not have big enough plane, can't avoid this problem through opening weeping hole or exhaust hole.

Disclosure of Invention

The utility model discloses solve above-mentioned prior art's shortcoming, provide a structure more optimizes, the better nut of preventing electrophoresis pocket liquid and pocket gas of result of use.

The utility model provides a technical scheme that its technical problem adopted: the electrophoresis pocket liquid and pocket gas prevention nut comprises a body, wherein the body of the nut is fixed on a suspension support, the lower surface of the body is a nut end surface, the nut end surface and the suspension support are welded and fixed, a long and thin groove is formed in the nut end surface, and two ends of the groove extend to the center and the outer edge of the nut end surface to form a discharge channel.

The end face of the nut is provided with a plurality of grooves which are uniformly distributed in a fan shape.

And a welding form of gas shielded welding is adopted between the end face of the nut and the suspension bracket.

And the welding position between the end face of the nut and the suspension bracket forms two sections of symmetrical welding seams along the outer edge of the end face of the nut.

The utility model discloses profitable effect is: the utility model discloses set up the long and thin recess of a plurality of at the nut end face, avoided welding back nut end face and support laminating completely sealed, can have the passageway of exhaust and weeping, under the prerequisite that does not change product technology and performance, pocket liquid or pocket gas when having avoided the electrophoresis, guaranteed the paint film quality.

Detailed Description

The present invention will be further explained with reference to the accompanying drawings:

as shown in figures 7 and 8, the electrophoresis pocket liquid and pocket gas preventing nut comprises a body 1, the body 1 of the nut is fixed on a suspension support 2, the lower surface of the body 1 is a nut end surface 4, the nut end surface 4 is welded and fixed with the suspension support 2, a slender groove 3 is arranged on the nut end surface 4, and two ends of the groove 3 extend to the center and the outer edge of the nut end surface 4 to form a discharge channel. The nut end face 4 is provided with a plurality of grooves 3, the grooves 3 are uniformly distributed in a fan shape, and the body 1 adopts a cold heading process. And a welding form of gas shielded welding is adopted between the nut end face 4 and the suspension bracket 2. The welding position between the nut end face 4 and the suspension bracket 2 forms two sections of symmetrical welding seams 5 along the outer edge of the nut end face 4, and because a plurality of grooves 3 are uniformly distributed on the nut end face 4, the end parts of the grooves 3 at the parts which are not welded are exposed and used for liquid leakage or air exhaust. As shown in fig. 7, 11, 12, the number of grooves 3 may be 4, or 5, or 6.

As shown in fig. 9 and 10, during electrophoresis, since the rest of the suspension bracket 1 of the body 1 is completely attached, the electrophoresis liquid is discharged along the channel formed by the groove 3; the air also can be discharged from this passageway, the utility model discloses a structural innovation, under the prerequisite that does not change product technology and performance, pocket liquid or pocket gas when having avoided the electrophoresis, guaranteed the paint film quality.

In addition to the above embodiments, the present invention may have other embodiments. All technical solutions formed by adopting equivalent replacement or equivalent transformation fall within the protection scope required by the utility model.
