Zusammenfassung:	The utility model discloses a double-medium four-way embedded rotary oil cylinder for a workpiece main shaft, which comprises a main shaft, a mandrel pull rod is coaxially arranged at the center of the main shaft, a rotary sleeve is coaxially sleeved on the outer wall of the mandrel pull rod, a cylinder cover is coaxially sleeved on the outer wall of the rotary sleeve, one end of the main shaft is coaxially sleeved with a worm gear pair, and the other end of the main shaft is connected with a circular truncated cone surface. The circular truncated cone face is connected with the cylinder cover through the cylinder body, and a piston is coaxially arranged in the center of the circular truncated cone face and right faces the mandrel pull rod. The rotary oil cylinder solves the problems that multi-channel double-medium sealing of an existing rotary oil cylinder is difficult, and the occupied space of an external rotary oil cylinder is large. 本实用新型公开了一种工件主轴用双介质四通嵌入式旋转油缸，包括主轴，主轴的中心处同轴设有芯轴拉杆，芯轴拉杆的外壁同轴套接有回转套，回转套的外壁同
