Problems solved by technology
[0007] (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;
[0008] (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
[0049] refer to figure 1 , is a robot bypass hydraulic pump control device disclosed in the present invention, including an execution pipeline 1, a power system and a hydraulic system, one end of the execution pipeline 1 is connected to the execution parts of the robot, and the other end is communicated with 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 communicates with 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 Outlet of hydraulic pump 2. The fluid discharged from the hydraulic pump 2 flows into the execution pipe 1 through the check valve 3 to provide driving force for the action of the actuator. When the fluid in the execution pipeline 1 flows in reverse or reaches the maximum rated working pressure, the check valve 3 is closed to prevent the fl...

The invention discloses a bypass-type hydraulic pump control device for a robot, and relates to the technical field of hydraulic control. The bypass-type hydraulic pump control device comprises an execution pipeline, a power system and a hydraulic system; one end of the execution pipeline is connected with an execution part of the robot, the other end of the execution pipeline communicates with the power system, and the power system provides driving force for the action of an execution part; the hydraulic system communicates with the execution pipeline and is used for controlling and adjustingthe pressure of the execution pipeline; and a bypass system used for stabilizing idling operation of the power system is further connected between the execution pipeline and the power system and is apiston-type assembly. Stable idling operation of a hydraulic pump under low pressure is achieved through the piston-type assembly, the operation stability and reliability of a hydraulic control device are improved, and the control precision of the execution part is guaranteed; and meanwhile the throttling loss and the overflow loss of a system can be reduced, the transmission efficiency of the execution part is improved, and the method is suitable for occasions where the difference between the fast forward speed and the work feed speed of the execution part is large.
Description
technical field [0001] The invention relates to the technical field of hydraulic control, in particular to a robot bypass hydraulic pump control device. Background technique [0002] With the development of high-tech in our country, the application of robots in life and production is becoming more and more important, and they are widely used in industrial manufacturing, warehousing and logistics, ports and terminals and other industries. The hydraulic pump is the power component of the hydraulic system. It is driven by an engine or an electric motor. It sucks oil from the hydraulic oil tank, forms pressure oil and discharges it, and sends it to the actuator. At present, most robots use hydraulic pumps and set up corresponding hydraulic control pipelines to independently control each executive part of the robot to realize the robot's actions. [0003] The present invention utilizes the patent retrieval system of the official website of the State Intellectual Property Office ...
