THE DESIGN OF THE THREE AXIS LINKAGE LASER CUTTING/ ENCARVING MACHINE
摘要
激光切割和雕刻加工是以数控技术为基础，激光作为加工媒介，使待加工材料在激光的照射下，被照射部位温度瞬间升高，发生熔化和气化，从而达到去除材料的目的。为了提高三轴联动激光切/雕一体机的加工精度并尽可能的降低制造成本，应用现代CAD/CAE技术来设计和分析三轴联动激光切/雕一体机的相关零部件十分必要。
本课题基于既定的性能指标，设计了一种基于同步带和滚柱丝杠传动的三轴联动激光切/雕一体机的机械结构。在整个设计过程中，首先对三轴联动激光切/雕一体机的发展状况进行了调研；其次根据设定好的性能指标，对机器进行整体的设计计算，并对关键零部件进行了校核；然后使用SolidWorks建模软件对三轴联动激光切/雕一体机进行了三维建模、整机装配以及运动仿真工作；最后再利用ANSYS完成对三轴联动激光切/雕一体机关键部件的静力学分析。主要完成工作如下：
1）进行了充分的市场调研，对三轴联动激光切/雕一体机的多种设计方案进行了详细的对比分析之后，确定了三轴联动激光切/雕一体机的总体方案。
2）根据所学知识设计三轴联动激光切/雕一体机，并使之达到设定的性能指标。
3）使用SolidWorks建模软件对三轴联动激光切/雕一体机进行了三维建模、整机装配以及运动仿真工作。
4）利用ANSYS对三轴联动激光切/雕一体机的关键部件进行了静力学分析，校核了方案的可行性和合理性。最后采购相关的零部件，进行了机器的实物装配。

Abstract
Laser cutting and encarving are based on numerical control technology, and laser is used as the processing medium, so that the material to be processed is irradiated by laser, the temperature of the irradiated part rises instantaneously, melting and gasification, so as to achieve the purpose of removing material. In order to improve the machining precision of the three axis linkage laser cutting/ encarving machine and reduce the manufacturing cost as much as possible, it is necessary to apply modern CAD/CAE technology to design and analyze the related parts of the three axis linkage laser cutting/ encarving machine.
Based on the established performance index, this paper designs a mechanical structure of three axis linkage laser cutting/ encarving machine based on synchronous belt and roller screw drive. In thewhole design process, the development of the three axis linkage laser cutting/ encarving machine is investigated. Secondly, according to the set performance index, the machine is designed and calculated as awhole, and the key parts are checked. Then the SolidWorks modeling software is used to carry out the three axis linkage laser cutting/ encarving machine. Three dimensional modeling, assembly and motion simulationwork, and finally the static analysis of the key components of the three axis laser cutting/ carving machine is completed by using ANSYS. The mainwork is as follows:
1) After a full market investigation and a detailed comparison and analysis of thevarious design schemes of the three axis linkage laser cutting/ encarving machine, the overall scheme of the three axis linkage laser cutting/ encarving machine is determined.
2) Design a three axis linkage laser cutting/ engraving machine based on the knowledge, and achieve the set of performance indicators.
3) Using the SolidWorks modeling software, the 3D modeling, assembly and motion simulation of the three axis linkage laser cutting/ encarving machinewere carried out.
4) Using ANSYS to analyze the key components of the three axis linkage laser cutting/ encarving machine, the feasibility and rationality of the schemewere checked. Finally, the relevant partswere purchased, and the physical assembly of the machinewas carried out.
