Robot direct-connection bypass type hydraulic pump control device

Abstract

The invention discloses a robot direct-connection bypass type hydraulic pump control device, and relates to the technical field of hydraulic control. The robot direct-connection bypass type hydraulicpump control device comprises an execution pipeline, a power system and a hydraulic system. One end of the execution pipeline is connected with an execution component of a robot, and the other end ofthe execution pipeline communicates with the power system. The power system provides drive force for the actions of the execution component. The hydraulic system communicates with the execution pipeline and is used for controlling and adjusting the pressure of the execution pipeline. A bypass system used for stabilizing idling running of the power system is further connected between the executionpipeline and the power system and is a directly-connected sliding valve type assembly. According to the robot direct-connection bypass type hydraulic pump control device, stable idling running of a hydraulic pump under low pressure is achieved through the sliding valve type assembly, the running stability and reliability of the hydraulic pump control device are improved, and the control precisionof the execution component is guaranteed. Meanwhile, the throttling loss and overflow loss of the system can be reduced, the transmission efficiency of the execution component is improved, and the robot direct-connection bypass type hydraulic pump control device is suitable for occasions where the difference between the fast forward speed and the tool feed speed of the execution component is large.

Description

technical field [0001] The invention relates to the technical field of hydraulic control, in particular to a robot direct-connection 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 Intellectua...

AI Technical Summary

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
