【正文】 畢業(yè)設(shè)計(論文)題 目: 數(shù)控機(jī)床刀庫與換刀裝置設(shè)計 摘 要 隨著機(jī)械加工業(yè)的發(fā)展,制造行業(yè)對于帶有自動換刀系統(tǒng)的高效高性能加工中心的需求量越來越大。換刀機(jī)械手的主要任務(wù)是,完全模擬人手的換刀動作,給機(jī)床主軸與彈簧夾頭提供相對轉(zhuǎn)動實現(xiàn)夾緊、放松刀具的動作。機(jī)械手應(yīng)具備足夠的轉(zhuǎn)矩,該轉(zhuǎn)矩還必須恒定(可調(diào) )。同時還應(yīng)使機(jī)械手具備結(jié)構(gòu)緊湊、占據(jù)空間小的特點,以適應(yīng)不同類型機(jī)床的換刀空間。為了實現(xiàn)數(shù)控加工中心主軸豎直放置,刀架軸線水平,刀庫的刀軸垂直情況下利用機(jī)械手實現(xiàn)自動換刀的動作。其中,機(jī)械手手臂可轉(zhuǎn) 90 。使加工中心功能有所提?升,更能滿足生產(chǎn)加工的需要,進(jìn)一步提高加工的自動化程度,提高生產(chǎn)效率。論文第二部分工作是討論設(shè)計整體及傳動方案,并對方案進(jìn)行分析優(yōu)化;選擇最佳的方案,接下來進(jìn)行相關(guān)的干涉及強(qiáng)度校核計算。自動換刀系統(tǒng)采用單片機(jī)或 PLC 控制,它通過幾條與主控機(jī)的聯(lián)絡(luò)信號線以及系統(tǒng)內(nèi)設(shè)置的自診斷、自適應(yīng)功能實現(xiàn)對換刀系統(tǒng)的全自動控制管理。加工中心具有自動換刀裝置,能做到一次裝夾,多工序加工,把許多相關(guān)的分散工序集中在一起,形成一個以工件為中心的多工序自動加工系統(tǒng),從而大大縮短了機(jī)床上零件的裝卸時間和更換刀具的時間,改變了過去小批量生產(chǎn)中一人、一機(jī)、一刀的局面。關(guān)鍵詞:換刀機(jī)械手,換刀空間,PLC,自適應(yīng)AbstractWith machinery and processing industries developing, the manufacturing industry with an automatic blade system for the efficient growing demand for highperformance processing center bee more and more. Blade mechanical hand main task is plete simulation manpower blade moves to the main axis of machine tools and equipment and provide power for scutlery,movements. Mechanical hand should have sufficient torque, the torque must be constant (scale). At the same time, they should also have the structure to mechanical hand tight, a small space characteristics to meet different types of machine tools condition. To achieve digital processing center axis vertical placement, tool carrier axis level, the knives use mechanical hand vertical axis achieve automatic blade moves. The manipulator arm can turn processing center functions have been enhanced so that it can better meet production processing needs, and further enhance the degree of automation of processing and improve production efficiency. The second part of paper is the discussion overall of the design and the programme of translation. Analysis the programme and choose the best option, followed associated with the calculation accuracy and intensity. PC or PLC system using automatic blade control it through several signal lines and liaison with centre puter system established since diagnosis, adaptive function to achieve the fully automatic control system for blade management. Processing center with automatic changer devices, a place can do more work processing, put many related to decentralization processes together to form a working center for the multiprocessing system automatically processes, thereby greatly reducing the machine tools, spare parts handling time and the replacement of cutlery time, changed the production of a small, one plane, cut situation.
