摘要

随着我国工业生产的飞速发展，自动化程度迅速提高，在自动化生产领域中，工业机械手是近几十年发展起来的。工业机械手的是从工业机器人中分支出来的。其特点是可通过编程来完成各种预期的作业任务，在构造和性能上兼有人和机器各自的优点，尤其体现了人的智能和适应性。机械手作业具有准确性和各种环境中完成作业的能力。机械手是一种能自动化定位控制并可重新编程序以变动的多功能机器，它有多个自由度，可用来搬运物体以完成在各个不同环境中工作。

在有机械手换刀的过程中，使用一个机械手将加工完毕的刀具从主轴中拔出，与此同时，另一机械手将在刀库中待命的刀具从刀库拔出，然后两者交换位置．完成换刀过程．无机械手换刀时，刀库中刀具存放方向与主轴平行，刀具放在主轴可到达位置换刀时，主轴箱移到刀库换刀位置上方，利用主轴Z向运动将加工用毕刀具插人刀库中要求的空位处，然后刀库中待换刀具转到待命位置．主轴Z 向运动将待用刀具从刀库中取出，并将刀具插人主轴。

Abstract

With the rapid development of industrial production, rapidly improve the degree of automation in the field of automated production, the industrial robot are developed in recent decades. Industrial machinery hands are from the industrial robot in the branch out. Its characteristics are available through a variety of programming to complete the tasks expected in the structure and performance on both machines and their respective advantages, in particular, reflects the people's intelligence and adaptability. Manipulator operations with accuracy and variety of the environment's ability to complete the operation. Manipulator is a position control can be automated and re-programmed to change the multi-functional machine, which has multiple degrees of freedom that can be used to move objects in order to complete in different environment.

In a mechanical hand exchange cutlery，those will be completed using a mechanical hand, the cutlery out from the main axis.At the same time, another mechanical hand take cutlery from tools storehouse, and then the two exchange locations. The whole process is completed。If the mechanical hand blade do not join in the process, cutlery storage direction with the main axis parallel. when cutlery arrive at the location which the the main axis can reach, the main axis of the knife blade box to the location above。Z axis movement will be used to complete the processing by cutlery inserted in the space required by department, and then for cutlery knife to be transferred to the standby database location. Z axis movement will return to remove the cutlery from tools storehouse and inserted into the main axis.
