Manipulator mechanical arm structure

Abstract

The invention discloses a manipulator mechanical arm structure. The structure comprises a clamping arm, a fixed base plate, an electric push rod, a connecting rod, a rubber air cushion, a movable seatand a placement seat, wherein the upper end of the clamping arm is rotationally connected with the fixed base plate through a hinge seat, the fixed base plate is fixedly connected to the electric push rod, the upper end of the electric push rod is fixedly connected to the movable seat, the lower end of the electric push rod is fixedly connected with the connecting rod through a connecting piece,the end, away from the electric push rod, of the connecting rod is rotationally connected with the clamping arm, the clamping arm is fixedly connected with the rubber air cushion, the rubber air cushion communicates with an inflation pump through an inflation pipe, the movable seat is arranged on a threaded lead screw and a sliding rail in a sleeving mode, and the threaded lead screw and the sliding rail are fixedly connected into a containing cavity formed in the placement seat. Through the arrangement of the clamping arm, the electric push rod, the connecting rod, the rubber air cushion andthe movable seat, the problems that when objects are grabbed, the grabbing force is inconvenient to control, the objects are prone to being damaged, most mechanical arms are complex in structure, anduse and operation are complex are solved.

Description

technical field [0001] The invention relates to the technical field of manipulator-related manipulator structures, in particular to a manipulator manipulator structure. Background technique [0002] With the continuous advancement of science and technology, manipulators are widely used in industry, life, and medical treatment. To take items that are far away, and in the medical industry, some disabled people need manipulators to assist in grabbing the required items. The manipulators in the above scenarios basically preset corresponding programs, and the manipulators are driven by program instructions. Completing the corresponding grabbing work, this technology is relatively common and mature, but this method also has certain limitations. These specialized manipulators are inconvenient to control the strength of grasping when grabbing objects, and are easy to damage the objects, and most of the mechanical arms have complex structures and complicated operations.
