Description

Technical Field

[0001] This utility model relates to the field of automobile manufacturing equipment technology, and more specifically, to a fixing device for vehicle mounting test of a deflector. Background Technology

[0002] In vehicle deflector installation tests, the main focus is on simulating the fixed installation state to check surface accuracy, straightness, dimensional deviations, etc., for assembly verification. Currently, bolt-fastening installation is commonly used, which typically suffers from complex operation and poor adaptability. Especially when dealing with different deflector models, frequent tooling changes are required, making operation inconvenient. Some improved solutions achieve dimensional adjustment by adding a sliding rail structure, but lack an effective dynamic stabilization mechanism. In high-speed tests, vibration can easily cause displacement, leading to distorted test data. Furthermore, traditional rigid connection methods cannot simulate the flexible deformation during actual driving, affecting the effectiveness of deflector optimization design. Therefore, in view of this, this paper studies and improves the existing structure to provide a fixing device for deflector installation tests, aiming to achieve a more practical purpose. Utility Model Content

It can use fastening mechanism one and fastening mechanism two in conjunction with the support seat to fix the workpiece with the inner side facing outward, and use fastening mechanism three and fastening mechanism four in conjunction with the support seat to fix the workpiece with the outer side facing outward. This realizes the rapid installation and fixing of guide vanes of different models, improves the overall stability of the fixing, and solves the problems of complex operation and poor adaptability of traditional bolt fastening installation, as well as the easy displacement of the slide rail structure due to vibration during high-speed testing, which leads to the distortion of test data.

[0018] 3. Beneficial effects

[0019] Compared with existing technologies, the advantages of this utility model are:

[0020] This solution uses fastening mechanisms one and two in conjunction with a support base to fix workpieces with the inner side facing outwards, while fastening mechanisms three and four in conjunction with a support base can fix workpieces with the outer side facing outwards.
