<p>PROBLEM TO BE SOLVED: To provide a work moving device which is enabled in high-accuracy position, high-speed transfer, and space saving by using a single-shaft actuator, and is high in rigidity against a radial load.SOLUTION: This work moving device has a single-shaft actuator 10 having a first slider 2, a second slider 3 and one piece of screw shaft 4. A work installation member 81 having a work installation face is fixed to either of the first slider 2 and the second slider 3, and the other is used by being fixed to a fixing face 93. Rail guide members 5 to 7 for guiding the movement of a guide rail 1 to the fixing face 93 are fixed to a plurality of points of the guide rail 1 in a longitudinal direction. The screw shaft 4 has one end part in an axial direction and the other end part in the axial direction which are formed with a first spiral groove 41 and a second spiral groove 42, respectively, which are in a mutually-inverted screw relationship. A nut of the first slider 2 has a spiral groove corresponding to the first spiral groove 41, and a nut of the second slider 3 has a spiral groove corresponding to the second spiral groove 42.</p> |
