Method for setting manipulator rotating mechanism of hydraulic system

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 [0001] The invention relates to the technical field of hydraulics, in particular to a method for setting a rotating structure of a manipulator of a hydraulic system. Background technique [0002] Hydraulic technology is one of the key technologies to realize modern transmission and control. Due to light weight and small size, various components of hydraulic transmission can be conveniently and flexibly arranged according to needs. Combining with the latest technology, it has a high degree of automation and is easy to operate and control. It is easy to realize linear motion and a wide range of stepless speed regulation. To achieve overload protection, mineral oil is used as the working medium, which can be self-lubricated relative to the moving surface and has a long service life. In recent years, hydraulic pneumatic technology is facing competition with mechanical transmission and electric transmission. For example, CNC machine tools and small and medium-siz...

Problems solved by technology

In recent years, hydraulic pneumatic technology is facing competition with mechanical transmission and electric transmission. For example, CNC machine tools and small and medium-sized plastic machines have replaced or partially replaced hydraulic transmission with electronically controlled servo systems; the main reason is that hydraulic technology has leakage and poor maintainability. Disadvantages; for this reason, efforts must be made to give full play to the advantages of hydraulic pneumatic technology, pay attention to the combination with electronic technology, and continuously expand the application field, while reducing energy consumption, improving efficiency, adapting to environmental protection needs, and improving reliability. These are the continued efforts of hydraulic pneumatic technology The goal is also the key to the success of hydraulic and pneumatic products in market competition

However, the existing hydraulic system components of this product have many problems from different perspectives such as operation methods, working methods, and complicated structures, which lead to inefficient work, heavy equipment weight, and high costs
