摘 要:臥式鏜銑數(shù)控機床是一種加工范圍極廣、自由度很大的機床，主要用來加工形狀復雜、要求精度較高的箱體類零件，銑削平面、鉆削、鏜孔和加工端面等。 盡管傳統(tǒng)的鏜桿伸縮式結(jié)構(gòu)，具有鏜深孔及大功率切削的特點，但近幾年來，隨著為高速運行作技術(shù)支撐的傳動元件電主軸、直線電機、線性導軌等得到廣泛應用，主軸系統(tǒng)設計也由傳統(tǒng)的鏜桿伸縮式結(jié)構(gòu)逐步向現(xiàn)代高速電主軸結(jié)構(gòu)轉(zhuǎn)變。 與國外同類產(chǎn)品相比，國內(nèi)產(chǎn)品結(jié)構(gòu)形式單一，產(chǎn)品運行速度、進給速度等性能與國外產(chǎn)品還有很大差距。 本文以鏜桿伸縮式結(jié)構(gòu)為基礎，在廣泛參考數(shù)控機床設計相關資料和吸收消化的前提下，完成了對機床主傳動系統(tǒng)和主軸進給系統(tǒng)的設計，以及主要傳動件的強度校核。 關鍵詞：臥式鏜銑床 主傳動系統(tǒng) 進給系統(tǒng)
ABSTRACT:NC horizontal boring and milling machine is a machine tool with a very wide range of processing and large degree of freedom. It is mainly used to machine Box Parts those which have complex shapes and high accuracy requirements, to mill plane, drill hole, bore hole and machine face etc. Though the traditional structure of telescopic boring bar has the characteristics of being able to bore deep hole and cut with high-power, recent years, as the elements such as Electric Spindle, Linear Motion Actuator and Linear Guides, etc, those which can provide technical support for the high-speed operation, were widely used, Spindle Designing transform from the traditional structure of telescopic boring bar to a modern high-speed electric spindle gradually. Compared with the similar products abroad, home products has a single form, and there are still a large gap of the product’s operation and feed speed and other properties between product home and abroad. This paper was based on the structure of telescopic boring bar and on the premise of widely referring to related and absorbing data of CNC machine tool design ,I complete designing for main drive of the machine tool, Spindle Feed System and the check of the strength of the main transmission parts. Key Words: horizontal boring and milling machine；main drive of the machine tool; Feed System |
