Title:
HYDRAULIC ACTUATION DEVICE
Document Type and Number:
Japanese Patent JP2018058146
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a hydraulic actuation device that, when performing simple work such as cutting of a power cable, automatically conducts an action for making a processing part return to a standby position according to a first action mode without requiring operation after the work, and that positions the processing part with precision according to a second action mode, in a case that positioning of the processing part is required as during crimping work of a terminal post or the like.SOLUTION: A hydraulic actuation device 10 includes: a slider (for example, a piston rod 72) which is moved from a standby position to a processing position with pressure oil generated by a hydraulic generation part 20; and a changeover part (for example, a spool 58 or a selector valve 96) which changes over an action mode between a first action mode for automatically conducting an action for returning the slider to the standby position when a motor no longer is operated by an operational unit (for example, a switch 27), and a second action mode for stopping the slider when the motor no longer is operated by the operational unit.SELECTED DRAWING: Figure 7
