For example, as shown in FIGS. 2 and 3, the door assembly of the vehicle 10 is sectioned along the AA and BB lines at the top and bottom of the front door 10a of the vehicle 10 as shown in FIG. 1. It comprises upper and lower door hinges (11, 12), which are fixed with bolts (13) for mounting them to the body (21).

The upper and lower door hinges 11 and 12 are mounted on the body 21 so that the best quality is achieved, and the upper and lower door hinges 11 and 12 are installed at the "L" of the body 21 to minimize the quality distribution. Good quality can only be achieved by "zero" matching on the face.

That is, when the upper and lower door hinges 11 and 12 are fastened to the body 21, the "L" is formed between the body 21 and the upper and lower door hinges 11 and 12 in order to minimize errors. "0" matching on the face should be made. The reason is that the gap and the step of the outer appearance of the body 21 change depending on the degree of "L" plane matching.

In order to smoothly fasten each part of the door assembly to the body 21, a fastening error may be reduced only when the contact between the body 21 and the upper and lower door hinges 11 and 12 is perfect.

For the same reason as above, the "L" plane is aligned by the door hinge setting system as shown in FIG.

As shown, the vehicle model is transmitted by the PLC device 30, receives the vehicle model and moves it to the cylinder 31 up to the unit 32 of the vehicle model. Here, the unit 32, which is a fixing device for aligning the upper and lower door hinges 11 and 12, aligns the upper and lower door hinges 11 and 12 with the door assembly in the selected vehicle type.

However, in the conventional door hinge setting system configured as described above, as described above in order to align the upper and lower door hinges 11 and 12, it is difficult to cope with multiple models by installing and arranging the individual units 32 for each vehicle type. The investment cost rises, and the jig structure becomes complicated.

In addition, it is difficult to secure high quality due to the complicated jig, and the time required for recovery of line failure is long due to the complexity of piping and wiring in case of line failure.

In addition, after aligning the upper and lower door hinges 11 and 12 in the jig, flow is generated in the upper and lower door hinges 11 and 12 when the robot moves to seat the door assembly on the body 21, thereby degrading the quality. Let's do it.

After setting the upper and lower door hinges 11 and 12 on the body 21, in order to calculate data values of "L" plane matching between the upper and lower door hinges 11 and 12 and the body 21. It takes a lot of work time. That is, the teaching time is excessive because the data value is calculated repeatedly.

In addition, "L" surface matching between the body 21 and the upper and lower door hinges 11 and 12, and the eccentricity of the upper and lower door hinges 11 and 12 holes and the body 21 holes are checked to improve the quality by robot teaching. Since it must be secured, the teaching time is excessive during line operation.

The present invention has been created to solve the above problems, the quality is improved, the teaching time is shortened, there is no need for a jig for setting the door hinge, the equipment is simple, so that the vehicle can cope with multiple models It is an object of the present invention to provide a door hinge setting system.
