【正文】 ure with the continuous, slow movement of the rotary feed, no parking will be loading and unloading the workpiece. According to the processing requirements of the two cutter head can also be rough at the same time, finishing Milling is a flat, keyway, gear and a variety of forming surface processing methods monly used. Processing the workpiece in the milling machine, the general adoption of the following types of clamping methods: (1) directly in the milling machine table clamping a large workpiece clamping often directly in the table, with stud, plate pactor, which need to dial indicator methods, tools such as zoned to find the needle surface and the cutter is processing relative position. (2) vice flat tool used for clamping the workpiece in the shape of a simple, small parts, general machine tools can be used in clamping vice in the mouth, the need to ensure that when used in machine vice the correct position. (3) dividing head with the workpiece clamping, the need for indexing of the workpiece, the general direct clamping head in the subdegrees. In addition, indexing of the workpiece without dividing head with clamping processing is also very convenient.(4) with Vshaped frame workpiece clamping method is generally applicable to shaft parts, in addition to having a better than neutral, but also to bear a greater cutting force. 銑床夾具設(shè)計特點 一、銑床夾具的主要類型及結(jié)構(gòu)形式銑床夾具主要用于加工零件上的平面、凹槽、鍵槽、花鍵、缺口及各種成形面。根據(jù)工件質(zhì)量、結(jié)構(gòu)及生產(chǎn)批量，將夾具設(shè)計成單件多點、多件平行和多件連續(xù)依次夾緊的聯(lián)動方式，有時還要采用分度機(jī)構(gòu)，均為了提高生產(chǎn)效率?？磕５淖饔檬鞘构ぜ@得輔助運(yùn)動，形成仿形運(yùn)動。定向鍵通過與銑床工作臺上的形槽配合確定夾具在機(jī)床上的正確位置；還能承受部分切削扭矩，減輕夾緊螺栓的負(fù)荷，增加夾具的穩(wěn)定性，因此平面夾具及有些專用鉆鏜床夾具也常使用。對刀裝置的結(jié)構(gòu)形式取決于加工表面的形狀。對刀塊和塞尺均已標(biāo)準(zhǔn)化（設(shè)計時可查閱相關(guān)手冊），使用時，夾具總圖上應(yīng)標(biāo)明塞尺尺寸及對刀塊工作表面與定位元件之間的位置。 若夾具體較寬，可在同一側(cè)設(shè)置兩個與銑床工作臺T形槽間等距的耳座；對重型銑床夾具，夾具體兩端還應(yīng)設(shè)置吊裝孔或吊環(huán)等以便搬運(yùn)。根據(jù)工件的進(jìn)給方式，一般可將銑床夾具分為下列二種類型：在銑削加工時，往往把夾具安裝在銑床工作臺上，工件連同夾具隨工作臺作進(jìn)給運(yùn)動。根據(jù)加工要求，也可用兩個銑刀頭同時進(jìn)行粗、精加工銑削加工是平面、鍵槽、齒輪以及各種成形面的常用加工方法。另外，不需分度的工件用分度頭裝夾加工也很方便
