Workpiece conveyor and machine tool |
摘要 |
A weight of a movable body is reduced by using two guides, smooth movement of the movable body is ensured, a decrease in life of the guides is prevented, and a workload during installation of the guides is reduced. A workpiece conveyor that conveys a workpiece includes chucks that hold a workpiece, and a movable body that supports the chucks and is movable in an X direction along first and second guides, which are disposed in parallel or substantially parallel spaced apart from each other, and the movable body includes a first structure guided by the first guide, a second structure guided by the second guide, and a joint that is provided between the first structure and the second structure, and allows one of the first structure and the second structure to swing with respect to the other about an axis of a swing shaft set parallel or substantially parallel to the X direction. |

1. A workpiece conveyor comprising:
a chuck that holds a workpiece; first and second guides disposed in parallel or substantially parallel and spaced apart from each other; and a movable body that supports the chuck and is movable in a first direction along the first guide and the second guide; wherein the movable body includes a first structure that is guided by and contacts the first guide, a second structure that is guided by and contacts the second guide, and a joint that is provided between the first structure and the second structure, and allows one of the first structure that contacts the first guide and the second structure that contacts the second guide to swing with respect to the other about an axis of a swing shaft, the axis of the swing shaft being parallel or substantially parallel to the first direction. |
