Claims

[Scope of utility model registration request]

A manipulator that transfers a workpiece to and from a workpiece holding section of a machine tool includes an arm with a workpiece gripping means, a main shaft that supports the arm and is rotatable and movable in the axial direction, and a rotational drive means for the main shaft, In a workpiece transfer device equipped with a cylinder unit that moves the main shaft in the axial direction, a spring is provided that transmits thrust in the workpiece pressing direction from a rod on the cylinder unit side to the main shaft side, and a spring is provided that resists the spring. A work transfer device comprising a switch for detecting relative movement between the main shaft and the rod on the cylinder unit side.
