Description

Stern shaft internal field machining tool Technical Field The utility model relates to the technical field of stern shaft machining, in particular to a stern shaft internal field machining tool. Background The stern shaft is a key component in a ship propulsion system, and the processing precision of the stern shaft has a crucial influence on the sailing performance and stability of a ship. In the processing process of the stern shaft, the inner wall and the outer wall of the stern shaft are required to be processed finely respectively so as to meet the design requirement. However, the existing processing tools have a plurality of inconveniences when processing the inner and outer walls of the stern shaft. For example, when processing inner wall and outer wall, often need to shift the stern shaft from one frock to another frock, not only increased complexity and intensity of labour of operation, but also easily cause the damage to the stern shaft in the transfer process, influence machining precision and product quality. In addition, the existing fixture is not flexible and stable enough to fix the stern shaft, and is difficult to meet the stern shaft processing requirements of different specifications and sizes. Therefore, a novel tool for processing the inner field of the stern shaft is urgently needed, the problems can be effectively solved, and the processing efficiency and quality of the stern shaft are improved. Disclosure of utility model The utility model mainly aims to provide a tool for processing the inner field of a stern shaft, which realizes efficient and accurate processing of the inner wall and the outer wall of the stern shaft and simultaneously improves the adaptability of the tool to the stern shafts with different specifications and the stability of the stern shaft in the processing process. In order to achieve the above purpose, the tool for processing the inner field of the stern shaft provided by the utility model comprises a base, a supporting structure and two supporting frames, wherein the two supporting frames and the supporting structure are arranged on the base, the supporting structure is positioned between the two supporting frames, a cross column is arranged on the supporting frames and is used for placing the stern shaft, a pushing piece is arranged in the cross column, an abutting piece is arranged at the output end of the pushing piece, and the abutting piece can extend out of the outer surface of the cross column to abut against the inner wall of the stern shaft, so that the outer wall of the stern shaft can be processed; When the cross columns at two sides are completely separated from the stern shaft, the stern shaft can fall on the supporting structure, and the supporting structure is used for fixing the stern shaft and processing the inner wall of the stern shaft.
