摘要
隨著時(shí)代的發(fā)展,機(jī)加工行業(yè)已經(jīng)非常的普及,但是對于大批量的復(fù)雜零件加工,還是要用專用機(jī)床來進(jìn)行加工。
本文設(shè)計(jì)的機(jī)床為加工大型油輪舵裝置鍵槽的機(jī)床,也可用于大型結(jié)構(gòu)件鍵槽的加工。舵裝置的鍵槽是內(nèi)孔鍵槽,孔為錐孔、盲孔,而且采用雙鍵聯(lián)接結(jié)構(gòu),尺寸大,加工精度較高。本文研究了該舵裝置鍵槽的加工工藝以及為加工鍵槽而設(shè)計(jì)的專用機(jī)床。
本機(jī)床是一臺(tái)專用的車銑床,其床身和總體結(jié)構(gòu)為一臺(tái)車床,切削功能為銑削,其總原理為將整個(gè)銑頭和傳動(dòng)軸通過大拖板的運(yùn)動(dòng),伸入孔內(nèi),用指狀銑刀來銑削加工內(nèi)孔鍵槽。通過大拖板的橫向運(yùn)動(dòng)來實(shí)現(xiàn)槽長的加工,通過中拖板和立塊的運(yùn)動(dòng)來分別實(shí)現(xiàn)槽寬和槽深的加工,另外通過一個(gè)定位銷及螺栓聯(lián)接實(shí)現(xiàn)主軸架的分度調(diào)節(jié),以實(shí)現(xiàn)水平、垂直四個(gè)正交方向鍵槽的加工。加工進(jìn)給的每一個(gè)往復(fù)運(yùn)動(dòng)中,中拖板的水平運(yùn)動(dòng)及滑塊的上下運(yùn)動(dòng)均由鎖緊機(jī)構(gòu)利用變頻器控制進(jìn)給電機(jī)和切削電機(jī)的轉(zhuǎn)速,實(shí)現(xiàn)進(jìn)給速度和切削速度的調(diào)整。該工裝是在一次裝夾的基礎(chǔ)上實(shí)現(xiàn)多處鍵槽加工,因而不僅能夠保證舵葉錐孔本身的加工精度,而且能夠保證對稱雙鍵槽的形位精度。此設(shè)計(jì)不僅可以減少工人勞動(dòng)強(qiáng)度,而且可以保證加工質(zhì)量,從而可以獲得更好的經(jīng)濟(jì)效益。

Abstract
With the development of the times, machine industry has been very popular, but large parts of the processing, they want to use a special machine for processing.
The processed products for large tankers rudder device keyway,Can also be used for large-scale structure of the processing keyway . The rudder device keyway to hole keyway , Hole of the conical hole, Not run through the holes, Moreover structure of two key connection , Large size , High precision machining. This is a presentation of the keyway installation of the rudder processing and for the processing and design of the keyway dedicated machine.
The machine is a dedicated Milling Machine, Its bed and the overall structure of a lathe, Cutting function of the milling, Principle of its total whole installation box cutter and the drive shaft extension units of a large Worktable movement, Enter the hole, With Finger-shaped cutter Milling to Processing the hole keyway. A large table of horizontal movement to achieve trough direction of the length of processing, And the second stage through the vertical direction of the movement to block the realization of the respective width and depth of processing, Through a marketing and bolts to achieve workstations adjust the angle , Achieve the level of four vertical direction on the cross-slot processing . Feed every one of the reciprocating movement , The second stage of horizontal movement and block movement of the people in campaigns by organizations using fixed frequency electrical machinery control mobiles and the processing speed of motor rotation , Achieving velocity mobile speed and processing speed of adjustment . The Tooling is a fixture on the basis of multiple processing keyway, thus can not only ensure the rudder itself leaves the cone hole machining accuracy, but also to guarantee the keyway symmetric double-precision. This design can not only reduce the labor intensity, but can guarantee the quality of processing, thereby be better economic benefits.
