Description

Technical Field

[0001] The utility model relates to the field of automobile parts detection, in particular to a rear inspection tool for the bent tube of a hinge of an automobile trunk cover. Background Art

[0002] Since the manufacturing process of the square tube car trunk hinge assembly involves multiple bending and forming, connection with the hinge base plate, and welding and installing nuts on the base, this series of steps requires extremely high precision. If the precision is not up to standard, the trunk lid will be offset after installation. In order to ensure product quality, the hinge needs to be strictly inspected after production. However, there are some problems with the existing hinge bending inspection fixture when fixing the bent pipe: first, the fixing structure is relatively complex, which affects the inspection efficiency; second, when fixing the bent pipe, it is easy to make it bear excessive pressure, which causes the bent pipe to deform, thereby increasing the defective rate and the risk of quality loss.

[0003] The existing authorized Chinese utility model announcement number is: CN217083540U, and the publication date is: 2022-07-29, which discloses a rear inspection fixture for bending a hinged pipe of a car trunk. The bent pipe body is placed in the head clamp, the inspection fixture clamp A, the inspection fixture clamp B and the tail clamp, and then the hand pressure push rod is pressed down. The output shaft of the hand pressure push rod drives the clamping mechanism to move toward the bent pipe body to achieve the effect of fixing the bent pipe body. The operator then locks the bent pipe body through the fixed pressure frame to prevent the bent pipe body from moving during the inspection process. The utility model can facilitate the operator to quickly fix the bent pipe body through this structural design, which improves the bending speed. The detection rate of the pipe body; by setting the scale A in the inspection fixture card A and the scale B in the inspection fixture card B, the operator can detect the bent pipe body more quickly and accurately; the bent pipe body is fixed by adopting a clamping mechanism; when in use, the output shaft of the hand-pressed push rod drives the connecting column in the clamping mechanism to move toward the bent pipe body, so that the fixing frame is connected to the bent pipe body and the bent pipe body is clamped to fix the bent pipe body. In this process, the spring frame on the inner side of the fixing frame is deformed due to pressure to reduce the pressure on the bent pipe body, thereby preventing the bent pipe body from being deformed due to pressure.

[0004] In the above scheme, the connecting column is pushed toward the bent pipe by a hand-pressed push rod, and the bent pipe is squeezed by a fixed frame on one side of the connecting column to achieve the effect of fixing the bent pipe. At the same time, a spring is arranged in the fixed frame to reduce the pressure on the bent pipe and prevent the bent pipe from deforming. However, the fixed frame is still in rigid contact with the bent pipe, and wear will still occur during the extrusion fixation, which requires further improvement and optimization.
