摘要

 軸類零件是機(jī)器中經(jīng)常遇到的典型零件之一。它主要用來(lái)支承傳動(dòng)零部件，傳遞扭矩和承受載荷。軸類零件是旋轉(zhuǎn)體零件，其長(zhǎng)度大于直徑，一般由同心軸的外圓柱面、圓錐面、內(nèi)孔和螺紋及相應(yīng)的端面所組成。 根據(jù)結(jié)構(gòu)形狀的不同，軸類零件可分為光軸、階梯軸、空心軸和曲軸等。
 在軸加工的程序中，鉆孔也是最主要的加工之一。無(wú)論，后續(xù)的加工是搪孔，擴(kuò)孔，以致于研磨，都是把鉆孔當(dāng)作第一工程。因此后續(xù)加工的成敗及順利與否，和鉆孔的結(jié)果是習(xí)習(xí)相關(guān)。鉆孔工作可以在一般的工具機(jī)上進(jìn)行，例如: 鉆孔機(jī)，銑床，中心加工機(jī)。但是，使用一般的工具機(jī)在大量生產(chǎn)的鉆孔工作而言，效率及速度上變的很低。所以現(xiàn)在市場(chǎng)上比較通用的是用鉆孔主軸頭/鉆孔動(dòng)力頭來(lái)鉆孔。
 所以對(duì)軸上孔的鉆夾具設(shè)計(jì)是非常有必要的。

Abstract
Shaft parts of the machine parts are often encountered in a typical one. It is mainly used to support transmission parts, transmission torque and load to bear. Rotating shaft parts is parts, and its length is greater than diameter, generally cylindrical shaft concentric cylindrical, conical surface, and hole and thread the end of the corresponding component. According to the structural shape of different parts can be divided into the optical axis shaft, stepped shaft, hollow shaft and the crankshaft and so on. Processing procedures in the shaft, the drilling process is also one of the most important. No matter, the processing is to keep out the follow-up hole, reaming, grinding so that all the drilling projects as the first. Processing, therefore the success or failure of follow-up and smooth it or not, and the results of drilling is related breeze. Drilling work in the general machine tools, such as: drilling machines, milling machines, machining centers. However, the use of machine tools in general in the mass production of the drilling work, efficiency and speed of change is very low. So now the market is relatively common spindle drill head / drill power drill head. Therefore, the drill hole axis fixture design is necessary. Keywords: Fixture assembly processing
