加工中心側(cè)銑頭結(jié)構(gòu)設(shè)計
摘要 本設(shè)計主要是根據(jù)設(shè)計要求,依據(jù)機械設(shè)計和機械制圖的基本原理對一臺重型數(shù)控龍門銑床的側(cè)銑頭進行結(jié)構(gòu)設(shè)計,該側(cè)銑頭能夠在X 方向和Z方向兩個方向上進行銑削運動。本設(shè)計主要分四部分:
第一部分是根據(jù)設(shè)計要求對側(cè)銑頭的結(jié)構(gòu)進行總體方案的設(shè)計,主要包括伺服進給運動和主運動方式的確定。
第二部分是利用機械設(shè)計基本原理對設(shè)計中伺服進給運動和主運動系統(tǒng)的機械部分的設(shè)計計算,主要包括進給電動機、主軸電動機、滾珠絲杠副的選則、計算和校核以及對同步帶和帶輪進行設(shè)計。
第三部分是根據(jù)所選擇設(shè)計的主要零件,先進行大體結(jié)構(gòu)設(shè)計,之后在此基礎(chǔ)之上,利用機械制圖的基本原理,應(yīng)用CAXA電子圖版對側(cè)銑頭的結(jié)構(gòu)進行二維設(shè)計,并生成三張二維裝配圖紙和一張二維零件圖紙。
最后一部分是依據(jù)所設(shè)計的二維圖,利用SOLIDWORKS軟件對側(cè)銑頭結(jié)構(gòu)中零件進行三維建模,并將所有建模零件進行裝配,生成三維裝配體;在此基礎(chǔ)上,利用該軟件做一個三維動畫,顯示裝配體內(nèi)部結(jié)構(gòu)及運動方式。

Structural Design of the Profile Cutter Head of
a Machining Centre
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 four 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.
The finally part is to model the parts of the profile cutter head, and create three dimensional drawings using SOLIDWORKS software according to two dimensional drawings designed in the third part;The following is to create a three-dimensional animation to show the inside structure of the three-dimensional assembly drawing and the motion manner using the software on the bases of the three-dimensional assembly drawing.
Keywords: Heavy numerically controlled plan miller, The profile cutter head, Structural design, total project design, two dimensional design, three dimensional modeling,three-dimensional animation。
