The importance of the door hinge, which is the connection mechanism of the door and the vehicle body, is that the safety connection of the door is realized by the hinge. If the hinge quality is good, the car door can still be opened for escape in the accident. At present, in the mounting process of a door hinge, the door hinge cannot be pressed due to the fact that the space is narrow before being fastened, or the door hinge is pressed through a complex mechanical device. If the compression is not arranged, an installation gap exists between the hinge installation surface and the vehicle body, the tightening torque can be lost by 30% -50%, and the reliability is poor; if the complex mechanical device is adopted for compaction, the reliability is reduced due to more tightening force transmission links, and insufficient compaction force or reduced reliability easily occurs. In the prior practice operation, the moment loss of the vehicle door caused by the fact that the hinge of the vehicle door is tightened and is not attached or the once assembly failure rate caused by the change of the gesture reaches about 15-20%, and when the finished vehicle is assembled, adjusted and repaired, the defect is that a hinge screw needs to be loosened, so that the paint of the vehicle is damaged, and the quality of the whole vehicle is affected.
When the hinge of the door is fastened, because the hinge plate of the door hinge has two sheets and can rotate around the hinge shaft, a gap exists between the hinge plate and the car body before the hinge is fastened, and the position deviation of the door is caused during the fastening. The posture of the vehicle door can be kept only when the frame is assembled in the posture of the vehicle door and the hinge surface to be fastened is completely attached to the vehicle body, and the position of the vehicle door reaches high precision after fastening.
