Abstract

The utility model relates to a lower plate overlap joint structure on sub vehicle frame, including sub vehicle frame upper plate and sub vehicle frame hypoplastron, mutual lock is connected between sub vehicle frame upper plate and the sub vehicle frame hypoplastron to fixed mutually through the welding, the biggest department in two R angles of symmetry is equipped with the groove of outside salient on the sub vehicle frame hypoplastron. The utility model discloses profitable effect is: the utility model has the advantages of simple and reasonable structure, the cost does not increase, and punching press sideline department face profile degree size obtains promoting, and welding process promotes the beat, and product welding deformation reduces, has effectively solved the problem of lower plate overlap joint difficulty.

Description

Lower plate overlap joint structure on sub vehicle frame

Technical Field

The utility model relates to a sub vehicle frame spare part structure, especially a lower plate overlap joint structure on sub vehicle frame.

Background

The lap joint structure of the upper plate and the lower plate of the existing auxiliary frame has the advantages that due to the long lap joint edge line of the upper plate and the lower plate, if the inner size of a certain length of the edge line of the upper plate and the lower plate fluctuates, the upper plate and the lower plate are easily dislocated, the difficulty in proper buckling the upper plate and the lower plate is large, and the upper plate and the lower plate are frequently required to be knocked on a clamp to be completely buckled in the welding process. And the welding seam length of the upper plate and the lower plate of the auxiliary frame is longer, so that the integral thermal deformation is large.

Disclosure of Invention

The utility model discloses solve above-mentioned prior art's shortcoming, provide a hypoplastron overlap joint structure on simple structure, the better sub vehicle frame of effect.

The utility model provides a technical scheme that its technical problem adopted: this kind of hypoplastron overlap joint structure on sub vehicle frame, including sub vehicle frame upper plate and sub vehicle frame hypoplastron, mutual lock is connected between sub vehicle frame upper plate and the sub vehicle frame hypoplastron to through welded fastening connection, the biggest department in two last symmetrical R angles of sub vehicle frame hypoplastron is equipped with the groove of outside salient.

The outward convex surface of the groove is rectangular.

The maximum R angle is positioned at the tangency position of different arc lines of the side edge of the lower plate of the auxiliary frame.

The height of the outward bulge of the groove is larger than the thickness of the side edge of the lower plate of the auxiliary frame, and the height is an outflow port of electrophoresis liquid during electrophoresis.

The utility model discloses profitable effect is: the utility model has the advantages of simple and reasonable structure, the cost does not increase, and punching press sideline department face profile degree size obtains promoting, reduces the workman and strikes the time that the hypoplastron made its lock complete, and welding process promotes the beat, reduces product welding deformation, has effectively solved the problem of upper and lower plate overlap joint difficulty for welding quality is more stable, and the product size is more stable.

FIG. 2 is a partial enlarged structural view of the maximum R angle;

fig. 3 is a schematic view of the structure of the subframe lower plate.

Description of reference numerals: the auxiliary frame upper plate 1, the auxiliary frame hypoplastron 2, the groove 3, the biggest department 4 in R angle.

Detailed Description

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

as shown in the figure, this kind of hypoplastron overlap joint structure on sub vehicle frame, including sub vehicle frame upper plate 1 and sub vehicle frame hypoplastron 2, mutual lock connection between sub vehicle frame upper plate 1 and the sub vehicle frame hypoplastron 2, and through welded fastening connection, the biggest department 4 in two symmetrical R angles on sub vehicle frame hypoplastron 2 is equipped with outside outstanding groove 3, the biggest department 4 in R angle is located the tangent department of the different pitch arcs of sub vehicle frame hypoplastron 2 side, the most easy dislocation department when going up the lower plate lock promptly, the rectangle is personally submitted to the outside arch in groove 3. Carry out configuration optimization, the outside protruding height in groove 3 is greater than the thickness of sub vehicle frame hypoplastron 2 sides for the step depth deepens, and therefore the lower plate should be located to match the clearance great, both makes stamping process avoid springback here as far as possible, and the problem of lower plate overlap joint difficulty is gone up in reasonable solution again, can release welding deformation stress moreover. Meanwhile, the groove 3 is also used as an outflow port of the electrophoresis liquid during electrophoresis, and the electrophoresis liquid can smoothly flow out from the groove during electrophoresis, so that the electrophoresis defect of electrophoresis such as electrophoresis non-electrophoresis caused by liquid pocket can be prevented.

The utility model discloses to go up lower plate overlap joint region at the biggest department in the R angle (the punching press is kick-backed, the most easy dislocation department when going up lower plate lock) carry out configuration optimization, at 2 grooving in sub vehicle frame hypoplastron, the step depth deepens, because the sideline overlength when having solved the lower plate overlap joint, the lock installation that leads to because of local size is undulant is more difficult, long sideline, long welding seam leads to the installation face, the big scheduling problem of locating surface welding deformation, make it is more convenient to go up the hypoplastron lock, the sub vehicle frame hypoplastron 2 avoids the resilience as far as possible when the biggest 4 punching presses in the R angle, the size is more stable.

In addition to the above embodiments, the present invention may have other embodiments. All the technical solutions formed by adopting equivalent substitutions or equivalent transformations fall within the protection scope claimed by the present invention.
