It is not limited by the electrical or chemical characteristics of the workpiecematerials. Thus it has been proved to be a promising and cost-effective machining methodfor hard and brittle materials, such as engineering ceramic, glass, stone, which has beenwidely used in many fields such as electronics, metallurgy, chemistry industry, machine,energy power, aviation and space flight.Effect of ultrasonic machining process is very significant, domestic and abroad constantly ultrasonic machining processing methods combined with general application and achieved good results. Ultrasonic machining has good surface quality, does not produce surface burns and surface modification layer. We propose to ultrasound processing and integration to process Whirling threads, in general whirlwind milling devices based on the structure of improvement, and ultrasonic devices to form a new compound technology and equipment, and is still supporting the use of ordinary tools ,flexibility of installation and use is also very good. So that, the improved ultrasound equipment can make up ordinary Whirling cold cutting low, particularly suitable for processing hard and brittle materials such as hard processing, significantly improving the quality of thread processing.Keyword：Whirlwind milling Ultrasound Screw threadultrasonic horn 前 言11 緒論31.1本課題來源及研究意義31.2 課題目前研究現(xiàn)狀42 超聲加工及旋風(fēng)銑的基本介紹72.1超聲波及其特性72.2超聲加工基本原理92.3 旋風(fēng)銑加工的基本介紹122.3.2旋風(fēng)銑削加工螺紋的特點142.3.3 旋風(fēng)銑削裝置介紹152.4 典型螺紋類工件的加工情況173 超聲旋風(fēng)銑加工工藝223.1 普通蝸桿方法加工的工藝223.1.1 零件工藝性分析223.1.2 毛坯選擇233.1.3 設(shè)計毛坯圖253.1.4機械工藝路線確定263.1.5 定位基準(zhǔn)的選擇283.1.6 設(shè)備及其工藝裝備確定283.1.7 車切削用量、工時定額確定293.2按旋風(fēng)銑削加工方法進(jìn)行的蝸桿加工324 超聲加工裝置設(shè)計344.1 超聲加工裝置的主要組成344.1.1 超聲波發(fā)生器344.1.2 超聲換能器364.2 超聲振動系統(tǒng)設(shè)計384.3 超聲變幅桿的設(shè)計394.3.1 超聲變幅桿394.3.2變幅桿材料的選擇424.3.3 變幅桿參數(shù)的設(shè)計434 4 1 變幅桿與換能器的連接與固定524.4 2 變幅桿的固定535 裝置的設(shè)計與選用555.1 電動機的選擇555.2 V帶傳動設(shè)計565.3 花鍵軸的設(shè)計585.5 各裝置設(shè)計605.5.1刀體和刀頭設(shè)計605.5.2 超聲加工主軸設(shè)計615.5.3 旋風(fēng)銑裝置整體設(shè)計625.5.4安裝于機床后示意圖63致謝64參考文獻(xiàn)65IV
