Abstract
The invention discloses a method for setting a manipulator rotating mechanism of a hydraulic system. The method comprises the following steps that firstly, a section of valve control circuit is additionally arranged between a variable pump and a hydraulic cylinder, a hydraulic control reversing valve is arranged in the valve control circuit, and a swinging motor is arranged in a manipulator rotating hydraulic system; then, a one-way valve and an overflow valve are additionally arranged in a hydraulic circuit connected with the periphery of the motor, and when an electromagnetic valve returns to the middle position, because the pressures at both ends of the cycloidal motor are unbalanced, if the pressure at the left end of the cycloidal motor is larger, the hydraulic fluid flows to a hydraulic tank through the one-way valve and the overflow valve; a three-position and four-way one-way valve is adopted as the one-way valve, and the locking of the hydraulic motor and the buffering of the hydraulic fluid are realized by the additional one-way valve and the overflow valve. The method has the beneficial effects that the stability and the easy speed adjustment in the linear movement are realized, the running precision of the machine is favorably improved, and the service life of the machine is prolonged; and meanwhile, the convenient and flexible arrangement is favorably realized according to requirements, the operation controllability is improved, and the labor strength is reduced.
Description
Technical field
The present invention relates to the hydraulics field, relate in particular to a kind of mechanism hand rotational structure setting method of hydraulic system.
Background technique
Hydraulics is one of key technology that realizes modernized transmission and control.Hydraulicdriven various element because lightweight, volume is little, can arrange easily and flexibly as required; realize conveniently, easily straight line motion, can realize large-scale stepless speed regulation, automatically realize overload protection in conjunction with state-of-the-art technology automaticity height and manipulation control, but adopt mineral oil as working medium relative movement face lubricating by oneself, long service life.In recent years, hydropneumatics faces the competition with mechanical transmission and Electrified Transmission, has adopted automatically controlled servo-system replacement or part to replace hydraulic transmission such as numerical control machine tool, middle-size and small-size molding machine; Its main cause is that hydraulics exists the shortcomings such as seepage, maintainability be poor; For this reason, must give full play to the advantage of hydropneumatics, attention and electronic technology combine, constantly enlarge application, reduce simultaneously energy consumption, raise the efficiency, adapt to the environmental protection demand, improve reliability, these all are the targets that hydropneumatics keeps punching, and also are the keys whether the hydropneumatic product is participated in market competition and won victory.But the hydraulic system assembly of existing this product exists a lot of problems from operating method, working method, numerous and diverse different amount such as structure, and this causes work poor efficiency, heavier, the high expensive of weight of equipment.
Summary of the invention
The purpose of this invention is to provide and a kind ofly be conducive to convenient processing and manufacture, can make the steadily easily speed governing of its straight line motion, can enhance productivity, be convenient to safeguard, possess the auxiliary mechanism hand rotational structure setting method that improves the hydraulic system of equipment operation ability, to solve many deficiencies of prior art.
Purpose of the present invention is come specific implementation by the following technical programs:
A kind of mechanism hand rotational structure setting method of hydraulic system mainly is comprised of following:
⑴ at first set up one section valve control loop between variable displacement pump and oil hydraulic cylinder, be provided with a pilot operated directional control valve in this loop, in mechanism hand rotating hydraulic internal system rotary actuator is installed;
⑵ set up an one-way valve and a relief valve in the peripheral oil circuit that connects of motor then, when solenoid directional control valve is got back to meta, because the gerotor motor pressure at two ends is uneven, can get back to fuel tank by one-way valve and relief valve when left end pressure is large;
⑶ one-way valve is wherein selected the 3-position 4-way one-way valve, cooperates extra one-way valve and relief valve can reach oil hydraulic motor locking and fluid buffering again.
The beneficial effect of the mechanism hand rotational structure setting method of hydraulic system of the present invention is: be conducive to convenient processing and manufacture, can make steadily easily speed governing of straight line motion, be conducive to improve the machine movement precision, can increase the service life; Simultaneously, be conducive to arrange easily and flexibly as required, can improve the operation controllability, reduce labor intensity.
Embodiment
The mechanism hand rotational structure setting method of the described hydraulic system of the embodiment of the invention, its key step comprises:
⑴ at first set up one section valve control loop between variable displacement pump and oil hydraulic cylinder, be provided with a pilot operated directional control valve in this loop, in mechanism hand rotating hydraulic internal system rotary actuator is installed;
⑵ set up an one-way valve and a relief valve in the peripheral oil circuit that connects of motor then, when solenoid directional control valve is got back to meta, because the gerotor motor pressure at two ends is uneven, can get back to fuel tank by one-way valve and relief valve when left end pressure is large;
⑶ one-way valve is wherein selected the 3-position 4-way one-way valve, cooperates extra one-way valve and relief valve can reach oil hydraulic motor locking and fluid buffering again.
