In the process of machining a workpiece by a numerical control heavy horizontal lathe, the tailstock sleeve is mainly used for propping up and supporting the workpiece, and the mandrel of the tailstock sleeve rotates along with the workpiece. The load operation performance of the tailstock sleeve part directly influences workpiece processing, and the tailstock sleeve part can only be installed in the tailstock due to no driving force and loading device, so that load operation is carried out in the whole machine debugging and processing process. If the tailstock sleeve part is problematic, the tailstock sleeve part needs to be detached from the tailstock for maintenance, the assembly period of the machine tool is affected, and great waste is caused to time and cost.
