Japanese Patent JP2016050621
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a straight actuation machine capable of transferring a load even if the load is not connected to a rod.SOLUTION: This invention relates to a straight actuation machine in which there are provided a driving source connected to one end part of a screw shaft to rotate the screw shaft; a nut engaged in thread with the screw shaft and moved in an axial direction through rotation of the screw shaft; and a rod connected to the nut at the other end of the screw shaft. There are provided the first detecting segment in which the extremity end of the rod is biased toward the extremity end side by a biasing member so as to detect whether or not the rod is moved to the driving source and the extremity end of the rod passes by the first position in an axial direction and the second detecting segment in which the rod moves to an opposite side of the driving source so as to detect whether or not the extremity end of the rod passes by the second position positioned at the driving source side rather than the first position; when it is detected at the second detecting segment that the extremity end of the rod passes by the second position, the driving source is stopped and in turn when it is detected at the first detecting segment that the extremity end of the rod passes by the first position, the driving source is driven.SELECTED DRAWING: Figure 1
