ACTUATOR, PARALLEL LINK MECHANISM USING THE SAME, AND LONG MATERIAL BENDING DEVICE |
摘要 |
The dimensions of the fitting part of an actuator are to be dramatically reduced while enabling control items such as a driving motor and a position sensor of standard designs to be fitted around outside the actuator. To achieve this purpose, the actuator is provided with a trunnion type universal joint including: a fitting shaft, holding members and a rotary block having a nut arranged in it; a ball screw that is screwed into the nut of the universal joint and, being operationally linked to a driving power source, can move the nut back and forth; and a ball screw guide that is provided on the universal joint and guides the back-and-forth moving direction of the ball screw.
