Valve cylinder integrated element, piston cylinder actuating module and modular fluid driving device

Abstract

The invention discloses a valve cylinder integrated element, a piston cylinder actuating module and a modular fluid driving device. The piston cylinder actuating module comprises a through hole connector element, a piston and a piston rod; the through hole connector element is provided with a piston hole, and a piston rod hole is formed in the front end of the through hole connector element; the piston is arranged in the piston hole and is in sliding sealed fit with the piston hole, and the piston rod penetrates through the piston rod hole and is in sliding fit with the piston rod hole; a holecavity of the piston hole is separated into a rod cavity and a rodless cavity through the piston; and the rear end of the through hole connector element is provided with a fixing through hole connector capable of achieving installation to other fixing components. The piston cylinder actuating module can be loaded on a valve body of a reversing valve to form the valve cylinder integrated element,and can further be fixedly connected with a fixing body of a related machine to form a fluid driving device, multiple piston cylinder actuating modules can be further loaded on the fixing body jointlyto form the modular multi-location linked fluid driving device, modular design is achieved under the condition that the structure is simplified, and the application range is wide.

Description

technical field [0001] The invention relates to the field of cylinders and hydraulic cylinders, and mainly relates to a valve-cylinder integrated component, a piston-cylinder actuation module and a modularized fluid transmission device. Background technique [0002] In order to simplify the external pipeline and shorten the distance between the directional control valve and the hydraulic cylinder of the air cylinder, there has been a trend of integration of control components and actuators in recent times. At present, there is cylinder valve integration, that is, the valve of the directional control valve The body is fixedly connected to the end cover or cylinder body of the cylinder or hydraulic cylinder. This kind of integrated design is not difficult for large and medium-sized cylinders. But, it is absolutely impossible for the miniature cylinder, because the cylinder body of the miniature cylinder is even smaller than the valve body of the directional control valve. Th...

Problems solved by technology

[0007] (1) There is an unnecessary rear end cover 5' and related static sealing ring 16' in the hydraulic cylinder, which not only has redundant functions, but also increases the manufacturing cost in vain, and has a large axial dimension;

[0008] (2) On the fixed body 2' of the relevant machine, the positions of the two threaded adapter holes of the oil pipe joint are fixed, there is no room for maneuver, and the flexibility is poor, which cannot meet the requirements of flexibility and individual customization

Therefore, the threaded cylinder pipe joint thread adapter hole 5" is completely redundant and unnecessary, and the resulting functional redundancy, size increase and waste can be imagined;

[0014] (2) Actually, engineering figure 2 The technical essential requirement of the multi-cylinder linkage pressure equalizing fluid transmission device shown is a multi-position linkage pressure equalization fluid transmission device, while the prior art provides a multi-cylinder linkage pressure equalization fluid transmission device, which results in functional redundancy. caused great waste;
