Description

Technical Field

[0001] The utility model relates to the field of inspection tools for automobile parts, in particular to an inspection tool used for inspecting the deformation of a front upper control arm blank of a front suspension. Background Art

[0002] In the automotive industry, the front upper control arm is a crucial component of the front suspension system, directly impacting the vehicle's handling and ride comfort. The manufacturing quality of the control arm has a crucial impact on its performance, making accurate measurement of the deformation of the control arm blank essential during production. Existing methods for measuring control arm blank deformation primarily rely on three-dimensional coordinate measuring machines (CMMs) or 3D scanners. CMMs use a high-precision CMM to scan the blank to obtain its precise dimensions and shape. While this method offers high accuracy, it is expensive and requires a long testing cycle, making it unsuitable for the rapid testing requirements of high-volume production lines. 3D scanners capture the blank's three-dimensional contour and compare it to a theoretical model on the design drawing to determine the deformation. While this method can provide detailed deformation data, the scanning process is time-consuming and requires high operator skill. Therefore, a testing fixture for measuring the deformation of front upper control arm blanks was designed to meet current testing requirements. Utility Model Content
