激光快速成型機光頭支撐控制架設計
摘 要
激光是一種經(jīng)受激輻射產(chǎn)生的加強光,它具有高亮度,高方向性,高單色性和高相關性四大綜合性能。激光加工是工件在光熱效應下產(chǎn)生高溫熔融忽然受沖擊波拋出的綜合過程。數(shù)控激光加工是常用的一種加工方法,激光快速成型機的加工對象:有機板、布料、紙、皮革、橡膠、厚紙板、密集版、發(fā)泡棉、美耐皿、玻璃、塑膠,以及其它非金屬。激光快速成型技術已廣泛用于機械工業(yè),電子工業(yè),國防和人民生活等許多領域。
光頭控制架架設計是激光快速成型機設計的主要部分。該部分包括激光路線的設計,導軌系統(tǒng)的設計,同步帶系統(tǒng)的設計三個部分。導軌系統(tǒng)在機架中主要起導向和支撐作用,其主要部件是導軌副。本設計中要求在二維平面內(nèi)實現(xiàn)數(shù)控加工,因此,可用兩組導軌副以及一些附件來滿足要求。第一組導軌副由兩根平行的直線導軌組成,與機床床身相連接。第二組導軌副位于一根矩形橫梁之上,橫梁固定在第一組導軌副的兩個動滑塊上。這兩組導軌副分別由一個步進電動機通過同步帶系統(tǒng)驅(qū)動,從而實現(xiàn)在X軸,Y軸方向的二維加工。

Abstract
Laser radiation is a shock through the strengthening light, it has a high-brightness, high-directional, high monochrome and high coherence of the four properties. Laser processing is part of the light and heat produced by high-temperature melting all of a sudden shock wave threw out the comprehensive process. The number controls the laser machine is in common use a kind of process the method, CNC laser engraving can be used for processing board, cloth, paper, leather, rubber, cardboard, intensive version of the foam, melamine, glass, plastic and other non-metallic materials .CNC laser engraving technology has been widely used in industrial machinery, electronic industry, national defense and people's lives and many other fields.
NC rack design laser engraving machine is a major part of the design. The laser line, including some of the design of the rail system design, the timing belt system designed in three parts. Rail system from the rack in the role of guidance and support, and its main component is the Deputy Guide. The design called for the realization of two-dimensional plane of the NC, therefore, can guide the two groups and some of the annex to meet the requirements. The first group of rails by two parallel linear guide components, machine tools and connected to bed. The second group of rails in a rectangular beams above the fixed beams in the first group of the two rails on the fixed slider. The two rails by a deputy stepper motor through the belt-driven system to achieve X-axis, Y-axis of two-dimensional processing.
Key words: Laser processing, Vice Guide, The timing belt
