Abstract

The present invention relates to a cowl cross bar inspection tool, and a support bar coupled to a coupling bracket of a center floor panel at the center of a rod-type main pipe is installed to protrude downward, and is coupled to a dash panel at both left and right ends of the main pipe. Welding brackets, and between the bracket and the support bar, a setting jig arm having a tooling hole is set at the distal end, and the cowl cross bar checker is coupled to the dash panel to check the assembly position and the seating surface of the vehicle body. At the same time, the left and right intervals of the dash panel are different so that an error can be corrected even when an error occurs in the assembly position and the seat surface.

Description

Cowl cross bar gumball {Cowl cross bar}

The present invention relates to a cowl cross bar inspection tool, and more particularly, combines the cowl cross bar inspection tool with the dash panel to check the assembly position and the seating surface of the vehicle body, and at the same time, the left and right intervals of the dash panel are different from the assembly position and the seating surface. It is related to cowl cross bar inspection that allows to correct the error even if a.

In general, even if a frontal collision occurs while the vehicle is running between the engine room and the dashboard, a cowl that improves the safety of the occupants by preventing the dash panels forming the various electrical equipment and body installed in the engine room from entering the cabin. A cross bar is mounted on the dash panel.

On the other hand, before assembling the cowl cross bar on the dash panel, the assembly position formed on the car body by mounting the cowl cross bar inspection tool at the cowl cross bar installation position in order to check whether the cowl cross bar mounting position is accurately reproduced on the dash panel. And assembly seats are checked.

However, in the related art, when the cowl cross bar inspection tool is mounted on the dash panel to check the mounting position and the assembling seats of the cowl cross bar, when the mounting position and the assembling seats formed on the vehicle body are moved to the same from side to side, it is not properly checked. As a result, when the actual cowl cross bar is mounted on the vehicle body, a simple left and right difference occurs, and thus, the vehicle cannot be properly installed.

On the other hand, if the above simple car occurs in the car body, it is not possible to find the bad parts of the car body using the cowl cross bar inspection tool, so in order to correct the bad parts of the car body, it is necessary to correct the car body using many corrective tools. there was.

An object of the present invention is to solve the problem as described above, the lower end portion in the center of the rod-type main pipe is installed to protrude to the lower support bar coupled to the coupling bracket of the center floor panel, the left and right both ends of the main pipe A bracket coupled to the dash panel is welded, and between the bracket and the support bar, a setting jig arm having a tooling hole is set at the distal end. In addition, it is possible to check and at the same time the left and right intervals of the dash panel is to provide a cowl cross bar inspection tool that can correct the error even when an error occurs in the assembly position and the seat surface.

Hereinafter, the technical configuration of the present invention with reference to the accompanying drawings in detail as follows.

The cowl cross bar gum ball of the present invention, as shown in Figures 1 and 2 and 3, the lower end in the center of the rod-type main pipe 10 is supported by the coupling bracket 21 of the center floor panel 20 The bar 11 is installed to protrude downward, and the bracket 12 coupled to the dash panel 30 is welded to both left and right ends of the main pipe 10, and the bracket 12 and the support bar 11 are welded. It is characterized by the technical configuration that the setting jig arm 13, in which the tooling hole 13a is set, is installed at the front end.

On the other hand, the tooling hole 13a formed in the setting jig arm 13 reveals that the center and the inner diameter of the assembly hole 31 formed in the dash panel 30 are formed to have the same size.

The present invention configured as described above checks whether the mounting position of the cowl cross bar is accurately reproduced on the dash panel 30 and at the same time checks the assembly position and the assembly seats formed on the dash panel 30, the center floor panel ( After coupling the lower end of the support bar 11 installed at the center of the main pipe 10 to the coupling bracket 21 of 20), the bracket 12 welded to both left and right ends of the main pipe 10 is dashed. Coupled to both ends of the panel 30 to determine the left and right spacing.

At this time, when the coupling bracket 21 is biased in one of the left and right directions on the center floor panel 20 and an error occurs based on the drawing, the setting jig arm 13 installed on the main pipe 10 is mounted. By using the tooling hole 13a formed in the setting jig arm 13 and the assembly hole 31 formed in the dash panel 30, and checking the assembly hole 31 and the tooling hole 13a. The amount of error formed in between is measured.

After measuring the error amount as described above, the cowl cross bar is separated from the dash panel 30, and the coupling bracket 21 installed on the center floor panel 20 by the error amount measured by the setting jig arm 13. Modify the installation location of.

On the other hand, after correcting the coupling bracket 21 by the amount of error, re-combining the cowl number bar checker 100 to the dash panel 30, and finally confirms the assembly position and seat surface of the dash panel () of course. , Simple left and right difference will be checked.

Therefore, in the present invention, by combining the cowl cross bar checker 100 with the dash panel 30, the assembly position and the seating surface of the vehicle body are checked and the left and right intervals of the dash panel 30 are different, so that an error in the assembly position and the seating surface is different. There is an effect to correct the error even if it occurs.

Claims (2)
