管道相贯线自动切割机器人支撑定位系统
摘要:相贯线切割机器人是用于管道相贯线切割的自动化工业机器人。它以加工精度高,自动化程度强以及效率出众等优点,将取代一直以来的手工作业。相对于现有的相贯线加工设备,一种低成本的相贯线切割机器人具有十分重要的研究意义及工程应用前景。本篇中将提出一种全新的切割机器人结构和独特的驱动分配原理,使得设计的机器人控制简单,加工效果好。并尽量控制其制作成本。该机器人已经在申请专利过程中。
本文着重于设计机器人的支撑定位系统。对其整个支撑定位系统进行结构设计。还包括工作状态下工作台的轴向位移和定位时自动升降两种传动方案,并对其校核。设计适合管道加工的专用夹具。设计过程中全部采用三维建模,直观的展示装配效果。另外,对其控制和切割原理进行简述。
