码垛机械手设计

摘要

在现代工业中，生产过程中的自动化已成为突出的主题。各行各业的自动化水平越来越高，现代化加工车间，常配有机械手，以提高生产效率，完成工人难以完成的或者危险的工作

随着工业自动化发展的需要，机械手在工业应用中越来越重要。用于再现人手的的功能的技术装置称为机械手。机械手是模仿着人手的部分动作，按给定程序、轨迹和要求实现自动抓取、搬运或操作的自动机械装置。在工业生产中应用的机械手被称为工业机械手。文章主要叙述了机械手的设计计算过程。

首先，本文介绍码垛机械手的作用，码垛机械手的组成和分类，说明了自由度和机械手整体座标的形式。同时，本文给出了这台机械手的主要性能规格参量。

文章中介绍了码垛机械手的设计理论与方法。全面详尽的讨论了码垛机械手的手部、腕部、手臂以及机身等主要部件的结构设计。

最后用PLC对码垛机械手进行控制

ABSTRACT

In modern industry, the automation of the production process has become a prominent theme.Increasingly high level of automation in all walks of life, modern processing plant, often with a mechanical hand in order to improve production efficiency, to complete it hard for workers to complete the work or risk

With the development needs of industrial automation, mechanical hand more and more important in industrial ed to reproduce the function of the technical staff of the device is called robot.Robot is modeled on the part of staffing action, according to a given program, automatically track and requirements capture, handling or operation of the automatic mechanical devices.Application in industrial production is known as industrial robot manipulator.This paper mainly describes the design of the manipulator calculation.

First, the article describes the role of robot palletizing, robotic palletizing composition and classification, indicating the degree of freedom and the coordinates in the form of the whole manipulator.Meanwhile, this paper, the machinery of the main performance specifications of hand parameters.

Article describes the robot palletizer design theory and prehensive and detailed discussion of the palletizing robot's hand, wrist, arm and body and other major components of the structural design.

Finally, PLC control for robotic palletizer

Key words: Palletizer robot, hydraulic transmission, hydraulic cylinder, PLC control
