摘要
本設(shè)計(jì)主要是根據(jù)設(shè)計(jì)要求，依據(jù)機(jī)械設(shè)計(jì)和機(jī)械制圖的基本原理對一臺重型數(shù)控龍門銑床的側(cè)銑頭進(jìn)行結(jié)構(gòu)設(shè)計(jì)，該側(cè)銑頭能夠在X 方向和Z方向兩個方向上進(jìn)行銑削運(yùn)動。本設(shè)計(jì)主要分三部分：
第一部分是根據(jù)設(shè)計(jì)要求對側(cè)銑頭的結(jié)構(gòu)進(jìn)行總體方案的設(shè)計(jì)，主要包括伺服進(jìn)給運(yùn)動和主運(yùn)動方式的確定。
第二部分是利用機(jī)械設(shè)計(jì)基本原理對設(shè)計(jì)中伺服進(jìn)給運(yùn)動和主運(yùn)動系統(tǒng)的機(jī)械部分的設(shè)計(jì)計(jì)算，主要包括進(jìn)給電動機(jī)、主軸電動機(jī)、滾珠絲杠副的選則、計(jì)算和校核以及對同步帶和帶輪進(jìn)行設(shè)計(jì)。
第三部分是根據(jù)所選擇設(shè)計(jì)的主要零件，先進(jìn)行大體結(jié)構(gòu)設(shè)計(jì)，之后在此基礎(chǔ)之上，利用機(jī)械制圖的基本原理，應(yīng)用CAXA電子圖版對側(cè)銑頭的結(jié)構(gòu)進(jìn)行二維設(shè)計(jì)，并生成三張二維裝配圖紙和一張二維零件圖紙。

Abstract
The design is mainly to design the profile cutter head structural of a heavy numerically controlled plan miller according as the rationale of mechanism design and theory of machines on the bases of design specification. The design is mainly divided into three parts:
The first part is a content of total project design of the profile cutter head Structure according as design specification, including confirming the manner of servo feed motion and the main motion.
The second part is design of calculations of machine parts of servo feed motion system and the main motion system according as the rationale of mechanism design. Its mainly including chooses the type, the calculation and the verification of the feed electromotor, the principal axis electromotor and the ball screw, and the design of hold-in range and synchronous pulley.
The third part is to design the mainly structure firstly on the bases of main parts choosed and designed in the second part, then to design two dimensional drawings, and create three assembly drawings and one detail drawings using CAXA software according to the rationale of theory of machines.
Keywords: Heavy numerically controlled plan miller, The profile cutter head, Structural design, total project design, two dimensional design。
