摘 要 數(shù)控平面磨床已經(jīng)向著精密化智能化復(fù)合化方向發(fā)展，精密平面磨床是重要的制造裝備，對(duì)于國(guó)家的制造業(yè)發(fā)展具有十分重要的意義。本畢業(yè)設(shè)計(jì)課題是設(shè)計(jì)一臺(tái)精密數(shù)控平面磨床，能用砂輪周邊磨削各類平面，可以加工各種難加工材料平面。 首先通過(guò)對(duì)國(guó)內(nèi)外平面磨床的發(fā)展現(xiàn)狀進(jìn)行論述，指出我國(guó)與國(guó)外在平面磨床發(fā)展水平的差距，突顯平面磨床研究的意義，引出課題。然后對(duì)當(dāng)前磨床布局的介紹，確定設(shè)計(jì)中磨床的總體布局。第三章從計(jì)算磨削力開始進(jìn)行磨床砂輪架的設(shè)計(jì)計(jì)算。接著進(jìn)行垂直進(jìn)給機(jī)構(gòu)的設(shè)計(jì)計(jì)算，完成之后設(shè)計(jì)立柱并選用合適的磨床數(shù)控系統(tǒng)。最后對(duì)設(shè)計(jì)結(jié)論進(jìn)行總結(jié)，并列出了本次設(shè)計(jì)中參考的文獻(xiàn)資料，末尾是對(duì)在設(shè)計(jì)中提供幫助的人的致謝。 關(guān)鍵詞：數(shù)控平面磨床；橫向進(jìn)給機(jī)構(gòu)；垂直進(jìn)給機(jī)構(gòu)；數(shù)控系統(tǒng)；床身 Abstract NC plane grinder has towards precision intelligent composite development,precision surface grinder is an important equipment manufacturing for manufacture industry. The graduation design topic is the design of a precision NC grinding machine, the periphery of the grinding wheel can use all kinds of plane, can process all kinds of difficult to machining materials. Firstly, the development situation of domestic and foreign plane grinder is discussed, pointed out that China and abroad on surface grinding machinedevelopment gap, highlighting the surface grinder research significance, present the topic. And then the current layout of the grinder, determine the overall layoutdesign of grinder. The third chapter is calculated from the design calculation togrinding wheel grinding force. Then the design and calculation of vertical feed mechanism, after the completion of design of column and select the appropriatenumerical control system of grinder. The design result are summarized, and listed the reference design,thanks to people who gave help at the end of the essay. Keywords: NC plane grinder; grinding wheel; the vertical feed mechanism; numerical control system
