Abstract

The utility model discloses a nut block positioning device of a nut plate of an automobile rear seat, which comprises a T-shaped fixing plate, a positioning pin arranged on a vertical arm of the fixing plate, and a positioning block arranged on a cross arm of the fixing plate and positioned outside a square plate of a nut block. The positioning block is used for limiting the position of the square plate of the nut block, so that the possibility of rotation of the nut block is reduced. According to the utility model, through the arrangement of the T-shaped fixing plate and the square positioning block, the rejection rate is 0, the problem of mounting the square hole of the rotary folding buckle of the nut block is thoroughly solved, the product quality and the production efficiency are ensured, and the production cost is reduced.

Description

Nut block positioning device of automobile rear seat nut plate

Technical Field

The utility model relates to a nut block positioning device of a nut plate of an automobile rear seat, and belongs to the technical field of automobile machining.

Background

In the processing of car back seat nut plate, it has a set of three holes on it, two of them are square holes, and one is the round hole, and finished product font distributes, and two square holes are used for the later stage to be connected with the buckle. The nut block is provided with a bottom plate and a hollow cylinder installed on the bottom plate, the hollow cylinder hole corresponds to a through hole formed in the bottom plate, the through hole corresponds to a round hole in the nut plate, the bottom plate is provided with a square plate, a protruding plate is arranged in the middle of one side of the square plate, and the protruding plate is located between two square holes after the nut block is welded and connected with the automobile nut plate. Nut plate and nut piece's welding is, passes cavity cylinder hole, through-hole and nut plate round hole through a locating pin earlier and later extrudees the nut piece, then carries out spot welding to the both sides of the square board of nut piece, and this technology is in the implementation process, exists because personnel place reasons such as not in place, causes the nut piece can be rotatory around the locating pin, leads to protruding board to shelter from one in two square holes, causes the unable installation buckle in later stage and scrap. And the rejection rate is about 10%, which seriously affects the production quality and greatly increases the production cost.

SUMMERY OF THE UTILITY MODEL

The utility model aims to overcome the defects in the prior art and provides a nut block positioning device of a nut plate of an automobile rear seat.

In order to achieve the purpose, the technical means adopted by the utility model is as follows: the utility model provides a nut piece positioner of seat nut board behind car, includes T shape fixed plate, installs the locating pin on the fixed plate erects the arm, installs on the fixed plate xarm, and is located the locating piece in the nut piece quadrangle board outside, the locating piece is the quadrangle piece.

The positioning block is used for limiting the position of the square plate of the nut block, so that the possibility of rotation of the nut block is reduced.

Furthermore, the number of the positioning blocks is two, and the positioning blocks are arranged in a shape of a Chinese character 'ji' with the finished positioning pin.

Through improvement, two round pin bodies are installed as positioning blocks, and the result shows that the nut block can be prevented from rotating to a certain degree at the moment, but the rejection rate is still about 4%; finally, a square positioning block is formed, and the rejection rate is 0.

The utility model has the beneficial effects that: through the setting of T shape fixed plate and square locating piece, thoroughly solved the rotatory folding buckle installation square hole's of nut piece problem, guaranteed product quality and production efficiency, reduced manufacturing cost.

Drawings

The utility model is further illustrated with reference to the following figures and examples.

FIG. 1 is a schematic structural view of the present invention;

fig. 2 is a schematic view of the assembly structure of the present invention.

In the figure: 1. the automobile nut plate comprises a fixing plate, 2, a positioning pin, 3, a positioning block, 4, an automobile nut plate, 5, a buckle mounting hole, 6, a nut block, 7 and a protruding plate.

Detailed Description

The nut block positioning device of the nut plate of the automobile rear seat shown in fig. 1 comprises a T-shaped fixing plate 1, a positioning pin 2 arranged on a vertical arm of the fixing plate, and a positioning block 3 arranged on a cross arm of the fixing plate and positioned outside a square plate of a nut block; the positioning block 3 is a square block.

As shown in fig. 2, the automobile nut plate 4 is provided with a group of three holes, two of the three holes are square holes and are buckle mounting holes 5, one hole is a round hole, the finished product is distributed in a shape like a Chinese character 'ji', the nut block 6 is provided with a bottom plate and a hollow cylinder mounted on the bottom plate, the hollow cylinder hole corresponds to a through hole arranged on the bottom plate, the hollow cylinder hole, the through hole corresponds to the round hole on the nut plate, the bottom plate is provided with a square plate, the middle part of one side of the square plate is provided with a convex plate 7, and after the nut block 6 is welded with the automobile nut plate 4, the convex plate 7 is positioned between the two square holes. The positioning block 3 is used for limiting the position of the square plate of the nut block 6, so that the possibility of rotation of the square plate is reduced.

The two positioning blocks 3 are arranged and arrayed in a shape like the Chinese character 'tu' with the finished positioning pin 2.

According to the utility model, through the arrangement of the T-shaped fixing plate and the square positioning block, the problem of mounting the square hole by the rotary folding buckle of the nut block is thoroughly solved, the product quality and the production efficiency are ensured, and the production cost is reduced.

Although particular embodiments of the utility model have been described and illustrated in detail, it should be understood that various equivalent changes and modifications could be made to the above-described embodiments in accordance with the spirit of the utility model, and the resulting functional effects would still fall within the scope of the utility model.
