Rotary swinging mechanical arm

Abstract

The invention discloses a rotary swinging mechanical arm which comprises a bracket panel, a servo motor, a rotation shaft, a first connection rod, a second connection rod and a mechanical arm, wherein the rotation shaft is movably fixed on the bracket panel; the servo motor is just capable of driving the rotation shaft to rotate along the axis relative to the bracket panel; one end of the first connection rod is fixedly connected with the rotation shaft and the other end of the first connection rod is rotatably and movably connected with one end of the mechanical arm; one end of the second connection rod is in sliding positioning connection with the other end of the mechanical arm and the other end of the second connection rod is in rotatable positioning connection with the bracket panel; a U-shaped groove is arranged on the bracket panel around the rotation shaft; and the rotatable and movable connection point between the other end of the first connection rod and one end of the mechanical arm just can be limited in the U-shaped groove. The mechanical arm is simple in structure and convenient to use, and has the effect of realizing the stop of the mechanical arm at any place in a motion trail.

Description

technical field [0001] The invention relates to a rotary swing mechanical arm. Background technique [0002] The rotating and swinging mechanical arms currently used are generally driven by cylinders, so that the mechanical arms can only reciprocate between certain two points, which is very inconvenient to use. Contents of the invention [0003] In order to overcome the above-mentioned defects, the present invention provides a rotating and swinging mechanical arm, which has a simple structure and can stop at any point in the motion track of the mechanical arm, and is very convenient to use. [0004] The technical solution adopted by the present invention in order to solve its technical problems is: a rotating and swinging mechanical arm, including a bracket panel, a servo motor, a rotating shaft, a first connecting rod, a second connecting rod and a mechanical arm, and the rotating shaft is movable and fixed on the on the bracket panel, and the servo motor can just drive ...
