Description

Single-drive electric self-adaptive manipulator based on connecting rod differential mechanism
Technical Field
The invention relates to the technical field of machinery, in particular to a single-drive electric self-adaptive manipulator based on a connecting rod differential mechanism.
Background
With the implementation of "industrial 4.0" and "chinese manufacture 2025", personalization and customization became features of today's society that revolutionized existing production patterns and lifestyles. In order to meet the requirement of individuation, a multi-variety and small-batch customized production mode and a non-uniform scene become a production normal state, wherein the key of success lies in the universality and adaptability of mechanical arm grabbing, and parts with different shapes, sizes and materials need to be processed by higher flexibility and adaptability. The self-adaptive manipulator is a special robot end effector, and can automatically eliminate the position error of the part by finishing the grabbing of irregular parts by using a self-adaptive technology, and can automatically adapt to the shape and size of the part and the change of the rigidity and flexibility of materials. In the complex and changeable tasks of the robot, the self-adaptability and the dexterity of the grabbing of the manipulator have great influence on the success or failure of the application of the robot, and are the main problems restricting the high-quality development of the robot industry at present.
Although the research of the adaptive manipulator has been greatly advanced at present, the adaptive manipulator cannot meet the industrial requirements in terms of compactness, cost performance, and the task requirements in complex environments and multi-task scenes. The existing self-adaptive manipulator generally adopts a plurality of motors to coordinate and drive a plurality of fingers to move, so that the cost of the manipulator is very expensive, and the problem of multi-motor coordination control needs to be considered; a few adaptive manipulators employ a single motor drive, which typically utilizes a gear differential or a pulley differential to coordinate multi-fingered motion. However, the former easily results in a heavy and bulky manipulator structure, and the latter can only realize small grabbing force by combining a rope driving mode. In addition, the existing adaptive manipulator focuses more on the design of the finger mechanism, and the research on the single-input multiple-output differential mechanism is less, which is the main reason for the slow development of the existing single-drive adaptive manipulator.
In industrial applications, a plate-shaped part is a common part, usually used for housings of various devices or products, often
The surface of the steel plate needs to be polished and ground. The plate-shaped part to be processed on the surface has high surface roughness, so that the sucking disc cannot be used for sucking and grabbing. The conventional self-adaptive manipulator is difficult to grab the periphery of the plate-shaped part, mainly because the thickness of the plate-shaped part is greatly different from the length and the width of the plate-shaped part, and the plate-shaped part is not beneficial to grabbing by the manipulator.
