Background Art

The function of the rail locomotive bogie is to support the rail passenger car body, reduce the vibration of the rail locomotive body, and improve the running stability of the rail locomotive. As the main part of the rail locomotive bogie, the seat is mainly used to connect the locomotive power components and play a role in stable driving and traction during the operation of the locomotive. Therefore, there are very high requirements for the processing accuracy and positioning accuracy of the rail locomotive seat. During the processing, the seat needs to be positioned on the CNC machine tool operating platform to ensure stable and smooth processing.

The traditional sleeve positioning method is: first determine the reference line of the sleeve by manual marking and calibrate it, then use multiple shims to support the sleeve on the CNC machine tool operating table, and finally tighten the bolts on the CNC machine tool operating table so that the pressure plate clamps and fixes the sleeve. However, the positioning operation is complicated, time-consuming and labor-intensive, the clamping positioning is unstable, the processing efficiency is low, and the clamping structure of the sleeve pressed by the pressure plate through the bolts is not firm, resulting in inaccurate sleeve processing and low product qualification rate.

Therefore, providing a vertical machining center tooling for a rail locomotive seat with accurate positioning is an urgent problem to be solved by those skilled in the art.
