[0001] The utility model belongs to the technical field of automobile manufacturing, and relates to a fixture for installing and limiting the rear wheel steering assembly of an automobile. Background Art

[0002] In the field of automobile manufacturing, the installation accuracy and quality of automobile assemblies are crucial for the performance and safety of the whole vehicle. The traditional installation method of automobile assemblies often relies on the experience of workers and simple measuring tools for measurement and positioning.

[0003] Manual operation is easily affected by subjective factors, resulting in large errors in measurement and positioning. Secondly, the accuracy of simple measuring tools is limited and it is difficult to meet the high-precision requirements of modern automobile manufacturing. Moreover, the traditional installation method lacks systematicness and standardization, and the operation methods of different workers may vary, thus affecting the consistency of products. In addition, due to the lack of special fixture for installation and inspection, during the process of installing and assembling the assembly parts, the length, angle and position of the assembly parts cannot be effectively controlled and detected, which may lead to unsatisfactory cooperation between the assembly parts and other components after installation, increasing the subsequent adjustment time and maintenance cost. Moreover, in the absence of accurate installation and positioning tools, installation errors are likely to occur, affecting production efficiency and product quality.

[0004] To solve the above technical problems, we have designed a fixture for installing and limiting the rear wheel steering assembly of an automobile. Summary of the Invention
