Description
Technical field
The present invention relates to cylinder technical field, specifically a kind of scalable series connection cylinder.
Background technology
Serial cylinders, the cylinder of multiple piston of i.e. connecting on a piston rod, is to guide piston to carry out straight line wherein
Reciprocating cylindrical metal parts.The advantage of serial cylinders is to obtain and is directly proportional with multiple piston effective areas
Output.The pulling force of serial cylinders and thrust all big than common cylinder, are generally also used as general reinforcement
Cylinder uses.Application: serial cylinders is used primarily in the fields such as printing, quasiconductor, Automated condtrol, robot.
Summary of the invention
It is an object of the invention to provide a kind of scalable series connection cylinder.
For achieving the above object, present invention employs following technical scheme:
A kind of scalable series connection cylinder, including the first hydraulic cylinder, the second hydraulic cylinder, the upper end of the first hydraulic cylinder and the second hydraulic cylinder

Pipeline is connected by the 3rd pipeline with second pipe, and described 3rd pipeline is provided with valve, and described valve is connected with control unit.
Its operation principle is: when piston upwards in the second hydraulic cylinder, the oil in the second hydraulic cylinder can pass through
Second pipe flows to the lower end of the first hydraulic cylinder, the oil in second pipe can be made to lead to by the unlatching of control unit control valve
Cross the 3rd pipeline flow-direction the first pipeline, because the oil in the second hydraulic cylinder can be controlled by the opening and closing of control unit control valve
Flow to the oil mass of the first hydraulic cylinder, thus realize controlling the rate of climb of the piston in the first hydraulic cylinder, thus realize scalable.
Additionally, the present invention also provides for following attached technical scheme:
Preferably, described control unit includes controlling the motor that valve rotates and the stepping electricity controlling motor
Machine controller.
Preferably, described controllor for step-by-step motor includes that central processing unit is connected by universal serial bus with central processing unit
Step motor drive unit, PC control unit, PLC control unit and alarm message module.
Preferably, described valve and control unit junction are additionally provided with hand-operated valve.
Compared to prior art, present invention have an advantage that
1, a kind of scalable series connection cylinder that the present invention provides, by being provided with valve at the 3rd pipeline, described valve is single with control
Unit connects, and the unlatching of control unit control valve can make the oil in second pipe pass through the 3rd pipeline flow-direction the first pipeline, because of
The oil mass of the first hydraulic cylinder is flowed to for the oil in the second hydraulic cylinder can be controlled by the opening and closing of control unit control valve, thus
Realize controlling the rate of climb of the piston in the first hydraulic cylinder, thus realize scalable.
