Document Type and Number:
Japanese Patent JPS5834210
Kind Code:
A
Abstract:
PURPOSE:To reduce working time when a drive controller is applied for robots or the like, by simultaneously driving hydraulic actuators each of which can be operated in at least two directions by means of a master cylinder which follows at least two cams driven by a same shaft. CONSTITUTION:A master cylinder 69 is connected through lines 85b and 86b to oil chambers 33 and 34 which are divided by a piston 35 of a hydraulic actuator 30. A pinion 38 engaged with a rack 39 which is integrated with a rack actuating shaft 39 of a rack actuator 40 is attached to one end of an actuating shaft 32 which is integrated with the piston 35, while a working arm 48 provided a chuck 49 at the tip thereof is firmly attached to the other end. A master cylinder 68 is connected to the rack actuator 40 through lines 85A and 86A while another master cylinder 70 is connected to a chuck actuator 50 inside the working arm 48 through lines 85c and 86c. Operation of the master cylinders 68 through 70 are controlled by grooved cams 61 through 63 via levers 65 through 67, respectively.
