[0002] With the development of industrial automation technology, reducing manual intervention and improving production efficiency have become important issues in various manufacturing processes. As a key component in the mechanical transmission system, the assembly of the end cover of the reducer is an important link in improving the reliability and precision of the entire mechanical product.
[0003] The traditional method of assembling the reducer end cover mainly relies on slow manual assembly, which not only has low production efficiency, but also easily causes damage or deformation of the end cover during manual handling, thus affecting the assembly accuracy. Secondly, the existing technology lacks cleaning of the end cover and the reducer assembly area before assembly. The contaminated dust will affect the press-fit effect between the end cover and the reducer, resulting in unstable product performance. Furthermore, the end cover is not properly heated, that is, the end cover is not expanded before being assembled with the reducer.
