Abstract
The invention discloses a one-piece hydraulic linear driving device, which includes an oil cylinder, an expansion link, a cylinder piston, an oil cylinder piston, an oil-conveying pipe, an oil pump, an electric motor, an electromagnetic valve, an oil cylinder front base, an oil cylinder rear base, an oil cavity and a gas cavity. The one-piece hydraulic linear driving device has the advantages of compact structure, large thrust, convenience for installation and control, and the like.
Description
Technical field
The present invention relates to a kind of integrated type hydraulic linear drive unit, the integrated type hydraulic linear drive unit of particularly using on a kind of automatic assembly line.
Background technique
The configuration of early stage numerical control machine tool, technical specification, mode of operation, technological requirement etc. all follow traditional machine tool, just utilize the rotation of computer-controlled servo motor, replace rotatablely moving of handwheel or motor, basic variation does not occur in the lathe driving mode.Yet because traditional screw pair is sliding friction pair, transmission efficiency is low, exist the shortcoming such as gap just to come out significantly when changing moving direction, becomes the bottleneck that numerical control machine tool further develops.Therefore, need to create a new generation, efficient and high-precision hydraulic linear drive unit satisfies numerical control machine tool to the requirement of machining accuracy and efficient.
Summary of the invention
The object of the present invention is to provide a kind of integrated type hydraulic linear drive unit.
The technological scheme that realizes above-mentioned purpose is: a kind of integrated type hydraulic linear drive unit, it is characterized in that, comprising: base, oil cylinder rear base, oil pocket and air cavity before oil cylinder, flexible rod, cylinder piston, oil cylinder piston, transport pipe, oil pump, motor, solenoid valve, the oil cylinder.
Be full of hydraulic oil in the described oil cylinder, be full of air in the described cylinder, described oil pump makes hydraulic oil flow by the diagram direction of arrow when described motor forward rotation, and described flexible rod extends forward, when described motor backward rotation, hydraulic oil flows toward opposite direction, described flexible rod is the described oil cylinder of indentation gradually, and described solenoid valve is when described operation of oil pump, described solenoid valve is opened, and hydraulic oil can flow.When described oil pump quits work, described solenoid closure.Hydraulic oil cannot flow.The invention has the beneficial effects as follows: the present invention have compact structure, thrust large, be convenient to install, the advantages such as control is convenient.
Description of drawings
Fig. 1 is structural representation of the present invention.
Embodiment
Below in conjunction with description of drawings preferred implementation strategy of the present invention.
Please refer to Fig. 1, provide a kind of integrated type hydraulic linear drive unit among the figure, comprised oil cylinder 1, flexible rod 2, cylinder piston 3, oil cylinder piston 4, transport pipe 5, oil pump 6, motor 7, solenoid valve 8, the front base 9 of oil cylinder, oil cylinder rear base 10, oil pocket 11 and air cavity 12.
Be full of hydraulic oil in the oil cylinder 1, be full of air in the cylinder, oil pump 6 makes hydraulic oil flow by the diagram direction of arrow when motor 7 forward rotation.Flexible rod 2 is extended forward.On the contrary, when motor 7 backward rotation, hydraulic oil flows toward opposite direction.2 of flexible rods are the indentation oil cylinder gradually.When the telescopic pipe fore and aft motion, in-oil cylinder oil chamber volume is changing.The effect of solenoid valve 8 is that solenoid valve is opened when operation of oil pump in addition, and surveying hydraulic oil can flow.When pump quits work, solenoid valve 8 closures.Can avoid like this because the micro-leakage of oil pump causes the change in location of flexible rod 2.
Principle of the present invention is: drive the directional flow of hydraulic oil in the oil hydraulic cylinder when utilizing common electric machine to rotate, as driving power, replaced the effect of linear electric motor, reached integrated hydraulic linear and driven effect.
Below embodiment has been described in detail the present invention by reference to the accompanying drawings, and those skilled in the art can make the many variations example to the present invention according to the above description.Thereby some details among the embodiment should not consist of limitation of the invention, and the scope that the present invention will define with appended claims is as protection scope of the present invention.
