Parallel robot capable of being dragged in small range for teaching

Abstract

The invention discloses a parallel robot capable of being dragged in a small range for teaching, and relates to the technical field of parallel robots. The problems that a parallel robot can only move in a designated direction during operation, actual teaching is inconvenient, and the degree of freedom is low are solved. The parallel robot capable of being dragged in the small range for teaching comprises a guide sliding rail, wherein a robot movable top cover is movably arranged on the bottom surface of the guide sliding rail, a robot connecting shell is arranged below the robot movable top cover, a power rod is arranged on the inner side of the end part of the robot connecting shell, adjusting connecting rods are movably installed on the two sides of the bottom end of the power rod, and a telescopic guide rod is arranged in the middle of the bottom surface of the robot connecting shell. According to the parallel robot, a dragging mechanism and an adjusting mechanism are arranged so that the working part of the parallel robot can be dragged in the small range, actual teaching can be carried out conveniently, the local degree of freedom of the parallel robot can be improved, and therefore working and teaching can be more convenient and faster.

Description

technical field [0001] The invention relates to the technical field of parallel robots, in particular to a parallel robot capable of dragging and teaching in a small range. Background technique [0002] With the rapid development of social economy, the parallel robot is referred to as PM, which can be defined as a moving platform and a fixed platform connected by at least two independent kinematic chains, the mechanism has two or more degrees of freedom, and is driven in parallel. A closed-loop mechanism, the parallel robot is characterized by no cumulative error and high precision; the driving device can be placed on or close to the fixed platform, so that the moving part is light in weight, high in speed and good in dynamic response. [0003] However, the existing parallel robot can only move in the specified direction during operation, which is inconvenient for actual teaching and has a low degree of freedom; therefore, it does not meet the existing needs, and we propose ...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a parallel robot that can be dragged and taught in a small range, so as to solve the problem that the existing parallel robot proposed in the background technology can only move in a specified direction during operation, which is inconvenient for practical use. Teaching, low degree of freedom and other issues
