摘 要
回轉(zhuǎn)工作臺(tái),即帶有可轉(zhuǎn)動(dòng)的工作臺(tái)面、用以裝夾加工工件并實(shí)現(xiàn)回轉(zhuǎn)和分度的機(jī)械設(shè)備,簡(jiǎn)稱為轉(zhuǎn)臺(tái)或第四軸。隨著現(xiàn)代工業(yè)的迅猛發(fā)展,機(jī)械加工對(duì)加工精度的要求越來(lái)越高,而回轉(zhuǎn)工作臺(tái)作為鏜床、鉆床、銑床等的重要附件,其性能對(duì)加工精度的影響極為顯著。傳統(tǒng)工作臺(tái)由于結(jié)構(gòu)、材質(zhì)等條件的限制,已經(jīng)難以滿足日益提高的技術(shù)需求。動(dòng)靜壓回轉(zhuǎn)工作臺(tái),是在傳統(tǒng)回轉(zhuǎn)工作臺(tái)的結(jié)構(gòu)基礎(chǔ)上,加入一層常轉(zhuǎn)中盤結(jié)構(gòu),并輔以靜壓支承技術(shù),在純液體潤(rùn)滑工作條件下實(shí)現(xiàn)差動(dòng)回轉(zhuǎn),從而克服如爬行等運(yùn)動(dòng)問(wèn)題,提高回轉(zhuǎn)工作臺(tái)的運(yùn)動(dòng)精度和抗震能力,擴(kuò)大工作臺(tái)的速度范圍,提高承載能力,使之具有較高的運(yùn)動(dòng)平穩(wěn)性,以符合更高的生產(chǎn)要求。本課題主要從主體結(jié)構(gòu)、傳動(dòng)方式、動(dòng)靜壓支承等方面探究了動(dòng)靜壓回轉(zhuǎn)工作臺(tái)的工作原理及其實(shí)現(xiàn)方式。

Abstract
Rotating table is a mechanical equipment which is for workpiece clamping fixture. With development of modern industry, the demand for machining precision has greatly increased. As an important accessory for machine tools, rotating table has obvious significance on working accuracy. But the traditional rotating table is limited by lagging design and mechanical structure, this leads to a huge disparity between traditional rotating table and increasing technical requirement. Hybrid rotating table is an improvement based on old-fashioned rotating table. Changes in the mechanical structure and hydrostatic support make performance a big progress. Hybrid rotating table works in the pure liquid lubricant condition, and it helps to cover some motion problems like “crawling”. The new design brings better kinematic accuracy and shock resistance, amplifies the range of speed and carrying capacity. It makes hybrid rotating table high stability. This topic is trying to explore the working principle and implementation about hybrid rotating table by means of designing the major structure, kind of drive, dynamic and static pressure bearing.
Key word hybrid rotating table; hydrostatic support; fuel supply circuit; worm drive; belt drive
