Description

Technical Field

[0001] The present invention belongs to the technical field of inspection tools, and particularly relates to an inspection tool for the side beam of the rear floor of an automobile. Background Art

[0002] The rear suspension includes longitudinal arms (with brackets, without brackets), subframes, coil springs, shock absorbers, etc. The installation positions and installation methods of the longitudinal arms, coil springs and shock absorbers of different rear suspensions with the vehicle body are not unified. The longitudinal arms of the rear suspension and the subframe of the rear suspension are usually assembled on the side beam of the rear floor. The side beam of the rear floor is successively an upper plane, a middle inclined plane and a lower plane from right to left (with a slight inclination at the right part for transition). The middle inclined plane is inclined downward from right to left, and is provided with a hollow hole and five mounting holes thereon (four of the mounting holes are arranged around the hollow hole and are the same). There is one mounting hole on the upper plane, two mounting holes and four grooves on the lower plane, and there is one mounting hole at the front contour of the side beam of the rear floor (located at the junction of the middle inclined plane and the lower plane). Mounting holes are distributed on the side beam of the rear floor. During later installation, bolts, etc. need to pass through, and accurate positions are required to better carry out the assembly. It is an important component in the production and processing of automobiles. In addition, the shape and contour requirements of the side beam of the rear floor are very high.
