Abstract: Through research on vehicle maintenance enterprises, it has been found that when automobile maintenance technicians assemble the camshaft and signal plate of the automobile engine, there is a significant assembly error in the position of the signal plate and the automobile engine camshaft, resulting in inaccurate camshaft position signals detected. The ignition time of the automobile engine is delayed or advanced, and there is a problem of significant assembly error. The paper focuses on the assembly problem of the camshaft and signal plate of Shanghai Volkswagen Octavia sedan. In response to the existing practical problems, the paper has consulted a large amount of literature and mapped the parts of the automotive engine camshaft and signal plate, obtaining accurate data and information. Combining with relevant knowledge of fixture design, a set of automobile engine camshaft and signal plate assembly fixtures has been designed, and automotive maintenance technicians use the assembly fixtures, which can quickly and accurately assemble the camshaft and signal plate, improving assembly quality and reducing labor intensity. As an ideal specialized assembly tool for automotive maintenance personnel, assembly fixtures have certain practical value.
