Multi-joint manipulator and mechanical arm

Abstract

The invention belongs to the technical field of manipulators, and particularly relates to a multi-joint manipulator and a mechanical arm. The multi-joint manipulator comprises a workbench, a supporting arm is installed on the workbench, a moving arm is connected on the supporting arm through a mobile regulating mechanism, rotating arms are symmetrically connected on a cavity connecting wall, mechanical clamping claws are installed on the rotating arms through guide air cylinders, a guide sliding rod is installed in the supporting arm, the guide sliding rod is slidably sleeved with a guide slide block, a movable arm is arranged on the side face of the guide sliding block; a first bevel gear is connected on another output end of a two-way motor through a coupling, the first bevel gear is symmetrically meshed with second bevel gears; an outer gear is located at the outer end of a cavity connecting arm, the outer gear is meshed with an inner toothed disc in a rotating manner; and the rotating arms are installed on the side wall of the inner toothed disc. According to the multi-joint manipulator and the mechanical arm, through the mutual cooperation of the symmetrically-arranged mechanical clamping claws, the rotating arms and the moving arm, not only the multi-directional and multi-angle opposite grasping operation for objects is realized, but also various object clamping operationis realized.

Description

technical field [0001] The invention belongs to the technical field of manipulators, in particular to a multi-joint manipulator and a manipulator. Background technique [0002] Manipulator refers to an automatic operating device that can imitate certain movement functions of human hands and arms to grab, carry objects or operate tools according to a fixed program. Manipulators can replace human heavy labor to realize mechanization and automation of production, and can operate in harmful environments to protect personal safety, so they are widely used in machinery manufacturing, metallurgy, electronics, light industry and atomic energy and other departments. [0003] Most of the manipulators are of multi-joint structure, that is, they include multiple manipulator arms, and two adjacent manipulator arms are movably connected, so that the manipulator can walk among multiple stations. [0004] However, most of the existing multi-joint manipulators drive multiple manipulators to...

Problems solved by technology

[0004] However, most of the existing multi-joint manipulators drive multiple manipulators to operate at multiple angles through a single power drive device. This kind of manipulator driven by multiple power sources is difficult to achieve fast or individual gripping operations on different objects, which in turn affects multi-joints. The manipulator works efficiently and stably; at the same time, when the multi-joint manipulator grips irregular pipes, due to the poor regularity of the object, the gripping force of the manipulator on the object is too small, which affects the safe grasping effect of the manipulator
