Robot leg extending-retracting mechanism

Abstract

The invention discloses a robot leg extending-retracting mechanism. The robot leg extending-retracting mechanism comprises a fixing chassis and a connecting rod; a connecting wire and a demonstrator are disposed on the side surface of the fixing chassis; the demonstrator is connected with the fixing chassis through the connecting wire; the connecting rod is partially embedded into the fixing chassis; and a power wire is disposed on the side surface of the fixing chassis and electrically connected with the demonstrator. According to the robot leg extending-retracting mechanism, a hydraulic pumpand a lifting rod are disposed and achieve adjustment of extending and retracting through the demonstrator, a rotary disc cooperates to rotate, then a robot can conveniently extend and retract, and the flexibility is improved; rolling wheels can be driven to move through a small arm shaft, so that the robot conveniently rotates for 360 degrees to write on a needed workpiece; position limiting isperformed through a position limiting plate during extending and retracting, so that extending and retracting of the lifting rod are limited to a certain degree; and position limiting can be performedthrough a dividing ruler during operation, and accurate measurement is achieved.

Description

technical field [0001] The invention relates to the technical field of telescopic mechanisms, in particular to a telescopic mechanism for robot legs. Background technique [0002] Generally, the robot arm has three degrees of freedom, that is, the stretching of the arm, the left and right rotation, and the lifting (or pitching) movement. The rotation and lifting movement of the arm are realized through the column of the machine base. The various movements of the arm are usually realized by the drive mechanism and various transmission mechanisms. The three degrees of freedom of the arm can have different combinations of movements (degrees of freedom). The Chinese patent "Scalable spherical robot mechanism" with the publication number CN103317512B includes external A ball frame, a ball telescoping mechanism, a rolling mechanism, the outer ball frame is composed of connecting blocks and connecting rods connected through hinges, forming three mutually perpendicular circular fram...

AI Technical Summary

Problems solved by technology

[0003] The existing robot legs are quite inconvenient to stretch and stretch. There are a large number of connecting lines in the robot, which is inconvenient to rotate and lift. We need further improvement
