摘要：現(xiàn)代LED封裝技術(shù)的發(fā)展基于數(shù)控技術(shù)，數(shù)控技術(shù)和數(shù)控機(jī)床理所當(dāng)然的成為制造業(yè)關(guān)注的焦點(diǎn)。工作臺作為被控對象，通過伺服電機(jī)實(shí)現(xiàn)精密定位，是數(shù)控機(jī)床不可或缺的部分。
本文以設(shè)計(jì)面向LED封裝的高速、高精密度工作臺為目標(biāo)，以機(jī)械動力學(xué)理論知識為基礎(chǔ)，深入的研究了十字型高速、高精密度定位平臺。完成的工作有伺服電機(jī)的選型和對工作臺機(jī)械部件進(jìn)行選型設(shè)計(jì)，其中機(jī)械部件的選型設(shè)計(jì)主要包括滾珠絲杠的選型、滾動導(dǎo)軌的選型、軸承和聯(lián)軸器的選型及主要主要支撐部件的外形設(shè)計(jì)，確保工作臺的定位精度為，重復(fù)定位精度為0.015mm。

Abstract:The development of modern LED encapsulation technology is based on numerical control technology, the numerical control technology and CNC machine , as a matter of course has become the focus of attention of manufacturing industry. As the controlled object ,Workbench realize precision positioning through servo motoring, which is an integral part of the nc machine tools.
Taking the high-speed and high -precision workable of LED encapsulation as object and mechanical dynamics theory knowledge as basis, this paper researches the cruciformed high-speed, high precision positioning platform thoroughly. The work finished includes the lectotype of servo-actuator and design of mechanical part workbench, in which the type selection of mechanical components includes the selection of ball screw ,rolling guaid ,bearing and coupling , and the configuration design of main propping components to ensure the positioning accuracy of worktable for , repositioning precision for 0.015 mm.
Keywords: workbench ball screw linear rolling guide vice
