Technical Field

[0001] The utility model belongs to the technical field of inspection tool manufacturing, in particular to an inspection tool for a front auxiliary frame of an automobile. Background Art

[0002] As competition in the automotive industry becomes increasingly fierce, in order to reduce development costs, the number of modified parts on the basis of the original car models is gradually increasing, and each car part needs to be tested before subsequent installation. Take the front subframe as an example. The front subframe is an important load-bearing component of the front axle of the car. It is connected to the body and bears the load of the vehicle's front axle. It is connected to the suspension and wheels at the bottom and fixes the steering gear. Its geometric size, precision and strength have a great impact on the safety, reliability and performance of the entire vehicle.

[0003] The existing Chinese utility model patent, CN 210141826 U, discloses a front subframe assembly inspection fixture for automobiles. The fixture features a simple structure, rational design, easy operation, and high inspection efficiency, and is suitable for inspecting the position of various mounting holes, locating holes, and through-holes on the front subframe. However, the fixture lacks a storage box for the inspection posts after inspecting the mounting and locating holes. This can easily lead to the loss of inspection posts due to operator error, hindering subsequent inspections and limiting its practicality.

[0004] Therefore, in order to solve the above problems, an automobile front subframe inspection fixture is proposed. Utility Model Content
