Design of replaceable simple-joint robot flexible hand

Abstract

The invention belongs to the field of mechanical manufacturing and provides a design of adopting replaceable simple-joint finger to clamp a series of workpieces of different shapes aiming at the defects that the hands of a common robot palletizer and a transfer robot are single in finger structure and have less possibility of reliably clamping the workpieces of different shapes and different sizes at present. The mechanism adopts a hydraulic system for driving; by virtue of controlling the stroke of the piston rod of a hydraulic cylinder and controlling the folding and unfolding states of the finger according to the clamping force requirements of workpieces of different shapes, corresponding clamping forces can be provided for satisfying the workpiece clamping requirements; the strokes of the designed piston rod are consistent; the fingers of the robot hand are connected with a connecting rod through dovetail grooves; the size of each dovetail groove on the connecting rod is fixed, the fingers of different shapes and sizes can be conveniently replaced only if matched dovetail groove interfaces are arranged, so as to meet the clamping requirements of different workpieces. The mechanism can be used for saving materials, saving the replacement time, increasing the working efficiency, rapidly designing and manufacturing corresponding replaceable fingers according to the shape and size requirements of different workpieces and meeting the high-efficiency production requirement.

Description

1. Technical field [0001] The invention relates to the design of a flexible hand of a robot, which belongs to the field of mechanical manufacturing. 2. Background technology [0002] Through the observation and analysis of the existing palletizing robot hands and handling robot hands, it is found that most of the existing robot hands are special-purpose manipulators designed for a specific job, so it mainly has the following problems: [0003] (1) The design is relatively simple. Generally, once a set of manipulators is designed and put into production and operation, its shape, structure, and size are fixed, which means that a set of manipulators can only perform a single job repeatedly. [0004] (2) Material waste is serious. When a specific job corresponding to the manipulator is completed, the manipulator is in an idle or abandoned state, which brings great losses to the production of the enterprise. [0005] (3) The scope of application is narrow. Because most roboti...

Problems solved by technology

[0008] (1) To solve the problem that the structure design of the existing robot hand is single and can only complete one or some specific tasks, design more sets of robot fingers to meet the requirements of completing more production tasks

[0009] (2) To solve the problem of waste of robot hand materials, design the robot hand drive equipment, fixed bracket and connecting rod into a uniform size model to increase the utilization rate of materials
