YAG激光加工數(shù)控工作臺(tái)設(shè)計(jì)
摘要：本次畢業(yè)設(shè)計(jì)的課題是YAG激光加工數(shù)控工作臺(tái)的設(shè)計(jì)。其中數(shù)控工作臺(tái)是該YAG激光器的主要組成部分。它決定了激光器的加工精度，它的每個(gè)方向的行程要滿(mǎn)足技術(shù)指標(biāo)，傳動(dòng)系統(tǒng)應(yīng)能滿(mǎn)足在給定使用條件下具有良好的三坐標(biāo)運(yùn)動(dòng)性和自鎖性。傳動(dòng)系統(tǒng)應(yīng)結(jié)構(gòu)簡(jiǎn)單，制造、維修方便?？偝杉傲?、部件的設(shè)計(jì)應(yīng)能滿(mǎn)足零件標(biāo)準(zhǔn)化、部件通用化和產(chǎn)品系列化及機(jī)床變型的要求。在對(duì)數(shù)控傳動(dòng)系統(tǒng)的功能、工作原理進(jìn)行分析后，根據(jù)任務(wù)書(shū)對(duì)該系統(tǒng)的要求及伺服電機(jī)與滾珠絲桿的設(shè)計(jì)，對(duì)傳動(dòng)系統(tǒng)采用何種結(jié)構(gòu)形式進(jìn)行了論證，并進(jìn)行了結(jié)構(gòu)優(yōu)化設(shè)計(jì)和計(jì)算。

YAG laser processing CNC machine design
Abstract：The graduation design topic is YAG laser processing CNC Table design. Numerical control worktable is the main component of YAG laser. It determines the laser machining accuracy, its each direction of travel to meet the technical indicators, the transmission system should be able to meet at a given condition has a good three coordinates movement and self-locking. The transmission system has the advantages of simple structure, convenient manufacture, repair. Assembly and spare parts, the design should meet the standardization of parts, components and serialization of products and machine tool variant requirements. In the numerical control drive system function, working principle is analyzed, according to the task the system requirements and servo motor and ball screw design, the transmission system adopts the structural form of the argument, and the structure design and calculation of optimization.
Keywords: YAG ；numerical control；3coordinate
