[0001] The invention belongs to the technical field of drilling equipment, and in particular relates to a multi-station linkage engine cylinder liner drilling equipment and a drilling method. Background Art

[0002] In the production and manufacturing process of engine cylinder liners, drilling is a key process. Traditional engine cylinder liner drilling equipment often has some problems. First, most equipment is single-station operation, and can only drill one cylinder liner at a time, which has low production efficiency and is difficult to meet the needs of large-scale production. Secondly, when switching between cylinder liners of different specifications, single-station equipment needs to spend a lot of time to adjust equipment parameters and replace tooling, and production flexibility is poor. Furthermore, due to the lack of collaborative operation of multi-station linkage, the overall equipment occupies a large area, and the connection between the various processes is not smooth enough, resulting in extended production cycles and increased costs. For this reason, an improved design of a multi-station linkage engine cylinder liner drilling equipment and drilling method is proposed. Summary of the invention
