Problems solved by technology
[0005] (1) There are large throttling losses and overflow losses in the hydraulic system, resulting in low hydraulic efficiency, which in turn affects the transmission efficiency of the robotic arm of the robot;
[0006] (2) When the hydraulic system is working under high load, the hydraulic pump needs to run idling under high pressure load. If things go on like this, the inside of the hydraulic pump will be damaged, which will affect the normal operation of the hydraulic pump and lead to changes in the stability and reliability of the hydraulic system. Poor, which in turn affects the control accuracy of the robotic arm

Embodiment 1
[0043] refer to figure 1 , is a direct-connection bypass hydraulic pump control device for a robot disclosed in the present invention, comprising an execution pipeline 1, a power system and a hydraulic system, one end of the execution pipeline 1 is connected to the robot's execution component, and the other end is connected to the power system. The power system includes a hydraulic pump 2. The hydraulic pump 2 is a variable displacement pump. The outlet of the hydraulic pump 2 is connected to the execution pipeline 1. The execution pipeline 1 is provided with a check valve 3 near the outlet of the hydraulic pump 2. The inlet side of the check valve 3 faces At the outlet of hydraulic pump 2. The fluid discharged from the hydraulic pump 2 flows into the execution pipeline 1 through the check valve 3, thereby providing driving force for the action of the execution components. When the fluid of the execution pipeline 1 flows in the reverse direction or reaches the maximum rated w...

The invention discloses a direct-connection bypass hydraulic pump control device for a robot, which relates to the technical field of hydraulic control and includes an execution pipeline, a power system and a hydraulic system. , the power system provides the driving force for the actions of the executive components. The hydraulic system is communicated with the executive pipeline for controlling and regulating the pressure of the executive pipeline. A bypass system for stabilizing the idling operation of the power system is also connected between the execution pipeline and the power system, and the bypass system is a spool valve type component directly connected. The invention realizes the stable idling operation of the hydraulic pump under low pressure through the sliding valve assembly, improves the stability and reliability of the operation of the hydraulic control device, and ensures the control precision of the execution components. At the same time, it can reduce the throttling loss and overflow loss of the system, improve the transmission efficiency of the execution part, and is suitable for the occasions where the speed of the execution part is greatly different from that of the work advance.
Description
technical field [0001] The invention relates to the technical field of hydraulic control, in particular to a control device for a direct-connected bypass hydraulic pump of a robot. Background technique [0002] With the development of high-tech in my country, the application of robots in daily production is becoming more and more important, and it is widely used in industrial manufacturing, warehousing and logistics, ports and other industries. The hydraulic pump is the power component of the hydraulic system. It is driven by an engine or an electric motor to inhale oil from the hydraulic oil tank, form pressure oil and discharge it, and send it to the actuator. At present, most robots use hydraulic pumps and set up corresponding hydraulic control pipelines to independently control each execution component of the robot to realize the action of the robot. The present invention uses the patent retrieval system of the official website of the State Intellectual Property Office ...
