Title:
THRUST EXPANSION DEVICE, EXPANSION UNIT, CONNECTING UNIT, AND THRUST EXPANSION SYSTEM
Document Type and Number:
Japanese Patent JP2020070927
Kind Code:
A
Abstract:
To ensure high expandability with respect to input actuators, other thrust expansion devices, and expansion units.SOLUTION: In a thrust expansion device 1b, an opposite surface that faces an output surface on which an output-side lid 5 where an output rod 72 enters or exits and a stop lid 6 are provided, is sealable by a sealing lid 3T with a plurality of orthogonal surfaces that are orthogonal to the output surface, and hydraulic chambers 8a, 8b and 8c for transmitting thrust to a piston portion 71 are made to communicate with the orthogonal surface side and the opposite surface side. A plurality of various types of actuators such as an air cylinder 100 are attached to the opposite surface or the orthogonal surfaces by way of an input-side lid 3 and a lid adapter 4, such that a hydraulic stroke OS of the output rod 72 is increased in the thrust expansion device 1b in which the sealing lid 3T is attached to seal the hydraulic chamber to the opposite surface or the orthogonal surfaces as needed, thereby ensuring high expandability with respect to the actuators, the thrust expansion devices, and expansion units.SELECTED DRAWING: Figure 10
