Background
The auxiliary frame of the automobile is an important component part of the chassis of the automobile, and has the main functions of providing installation and support for key parts such as a suspension system and a power assembly of the automobile, and playing an important role in reducing vibration and noise, improving assembly efficiency and improving safety and comfort of the automobile. As shown in fig. 1, the auxiliary frame is generally in a narrow U shape, and a U-shaped opening structure is further arranged in the middle of the auxiliary frame for connecting with other parts of the automobile. Therefore, the assembly accuracy and the product performance of the vehicle are affected by the gear opening size of the auxiliary frame, particularly the distance between the mounting holes on the two side wall surfaces of the gear opening structure.
However, existing measurement techniques have a number of difficulties in detecting subframe shift-out dimensions. On the one hand, the detection tools such as calipers which are commonly used at present have limitations in measuring the open gear size of the auxiliary frame although the operation is simple. Because the auxiliary frame structure is complicated, the influence of factors such as operating personnel technical level, measurement angle and the like is easy to receive when the manual work uses the slide caliper rule to measure, leads to measuring error great. In addition, the caliper measurement requires frequent contact and adjustment of the measurement position, which is not only inefficient, but also prone to damage to the subframe surface.

The detection tool can realize measurement of the U-shaped structure, but is mainly aimed at the outside molded surface, and the detection precision of the space between the inner mounting holes is insufficient.
In summary, when the existing measuring technology and tool are used for detecting the opening size of the auxiliary frame of the automobile, especially the distance between the mounting holes on the two side wall surfaces of the U-shaped opening structure, the problems of low measuring precision, inconvenient operation, easy damage to products and the like exist, and the requirements of modern automobile manufacturing on high-precision and high-efficiency detection are difficult to meet.
