Abstract
The utility model discloses a digital hydraulic power pack. The digital hydraulic power pack comprises an oil tank, wherein a bidirectional oil pump is arranged inside one end of the oil tank and is fixed on the end cover at the end of the oil tank, the bidirectional oil pump is provided with an oil inlet pipe and an oil outlet pipe, the oil inlet pipe and the oil outlet pipe stretch out of the oil tank and are connected with a hydraulic executive component, and the bidirectional oil pump is externally connected with a coupler, a servo motor, a driving device and a PLC in sequence. According to the digital hydraulic power pack, the PLC outputs a signal to the stepping driving device through a program, the signal is then transmitted to the stepping servo motor and is converted into angular displacement, and pressure energy is generated by the rotation of a bidirectional gear pump to drive any hydraulic actuator; the stepping motor can rotate in the positive direction and in the negative direction through the PLC, the switching between an oil inlet and an oil outlet can be achieved by the bidirectional gear pump under the driving of the stepping motor, and the reversing of the hydraulic actuators when the hydraulic actuators move back and forth is achieved. The digital hydraulic power pack has the advantages that the number of various control valves used in a traditional hydraulic transmission process is reduced, the reliability is improved, digitization of a traditional hydraulic cylinder is achieved, and the improvement of the traditional hydraulic technique is promoted.
Description
Technical field
The utility model relates to a kind of digital hydraulic power bag, belongs to the hydraulic equipment technical field.
Background technique
In traditional hydraulic transmission, hydraulic equipment is moving direction, speed and the position of controlling common oil cylinder by various hydrovalves.In order to satisfy various requirement, hydraulic pressure projector model utility the hydraulic element of hundreds of specification, and in order to obtain accurate control, again model utility servovalve and Proportional valve, but the machining accuracy of these two kinds of hydrovalves has become insoluble problem in the domestic industry, and these two kinds of valves are very harsh again to the requirement of each side such as fluid and environment in use, if a valve has gone wrong, whole system has just been paralysed so.Along with developing by leaps and bounds of modern science and technology, automation, be digitized into the direction into mechanical technique development, and then traditional mechanical automation, digitized quick growth have also been driven, hydraulics is as the part of traditional mechanical technique, and oil hydraulic cylinder is combined togather as the executive component of hydraulic system also increasing and electronic technology.
The model utility content
The purpose of this utility model is to provide a kind of digital hydraulic power bag, reduces the use amount of various control valves in the conventional hydraulic transmission, improves reliability, and then realizes the digitizing of conventional cylinder promoting the conventional hydraulic development of technology.
To achieve these goals, the technical solution of the utility model is: a kind of digital hydraulic power bag, comprise fuel tank, and in described fuel tank one end two-way oil pump is set, be fixed on the end cap of this end of fuel tank, two-way oil pump is provided with the turnover oil pipe, stretches out the fuel tank outside, is connected with hydraulic actuator, two-way oil pump connects coupling outward, described coupling is connected with actuating motor, and described actuating motor is connected with driver, and driver can be compiled controller with PLC and be connected.
Further, described fuel tank is leakproof fuel cell, and the other end of fuel tank arranges flange, can fixedly connected hydraulic actuator.
Further, described two-way oil pump connects the repairing pipe, communicates with fuel tank internal.
Further, described coupling arranges coupling guard outward, is fixedly connected on the end cap outside of fuel tank.
Further, described two-way oil pump is double-direction gearpump.
Further, described actuating motor is step-servo motor.
Further, described driver is step actuator.
Digital hydraulic power bag of the present utility model, PLC can compile controller and output signal to step actuator by programming, step actuator is passed to step-servo motor after the output signal of PLC is transformed, step-servo motor is converted into angular displacement to the electrical pulsing signal that receives, step-servo motor rotates together by coupling, double-direction gearpump like this, double-direction gearpump rotates and produces the pressure energy, and pressure can drive any hydraulic actuator by the turnover oil pipe.Step-servo motor can be compiled controller by PLC and can realize rotating and reverse, and double-direction gearpump can realize also that under the drive of step-servo motor oil inlet and outlet exchanges, and so just can realize the function that hydraulic actuator commutates back and forth.The repairing mouth act as the fluid that replenishes and leak the turnover oil pipe, fuel tank is a Seal cage, guarantees that fluid does not leak.Fuel tank rear flange place can link hydraulic actuator, and it is compact that entire equipment is installed, and monnolithic case is attractive in appearance.But also can change out different electrical pulsing signal by the different operation programming of PLC, thereby realize the different rate request of hydraulic actuator.Digital hydraulic power bag of the present utility model, the use amount of various control valves improves reliability in the transmission of minimizing conventional hydraulic, and then realizes the digitizing of conventional cylinder promoting the conventional hydraulic development of technology.
