摘 要
本次毕业设计是围绕着CA6140机床方刀架的工艺工装来展开的。内容主要包括以下几个方面：设计零件的加工工艺（包括切削用量工时等计算）设计两套专用夹具，对其中一套进行拆画。作出一万八千字的说明书。
方刀架的主要功用就是通过装在刀架上的其它零件夹紧刀具，换刀时，在手柄转动下，带动方刀架回转，以达到换刀的目的。
因为工件属于大批量生产，宜采用专用夹紧装置。所以为了适应生产需要，采用组合钻床，设计专用的钻模板，在回转工作台上进行多工位加工。
机床夹具的确定是一次十分重要的设计程序，方案的设计优劣往往直接决定夹具设计的可行性。所以，方案的确定需经充分的研究和讨论来确定最佳方案。

由于 液压传动具有许多优点，如结构紧凑，体积小，重量轻，反应快，承载能力大；较易实现无级调速，调速比大；运动平稳；易于实现自动化；并能实现较复杂的自动化工作循环；具有自润滑能力；磨损小，寿命长；液压元件易于实现通用化、标准化，便于大批量生产。所以，本次所设计的夹紧方式就采用液压压紧。

Abstract
This graduate design is around the square knife in bed in machine in CA6140 craft work packs to launch of.The contents includes primarily below a few aspects:Designing the spare parts processes the craft( include to slice 削 dosage man-hour etc. calculation) designs two sets of appropriations tongs, as to it's inside a set of proceedings dismantles the painting.Make a manual for 18,000th words.
The square knife an other spare parts for of main effect is passing packing on the knife clips the tight knife has, changing the knife, the in hand handle turns to move the bottom, arousing the square knife a purpose for turning round, then attaining changing the knife.
Because the work piece belongs to the large quantity measures production, the proper adoption appropriation clips the tight device.So produce the demand for the sake of the orientation, adoption combination drill the bed, design to drill the template appropriatively, at turn round the work on the stage proceed many the work processes.
It is design good and bad that machine bed tongs really settle that once very important design procedure that possibility, the project usually decides directly the tongs design.So, the project really settles to need through the sufficient research with discussion to certain the best project.

Because the liquid presses to spread to move to have many advantages, such as construction tightly packed, the physical volume is small, the weight is light, responding quick, load the ability is big;Than realizes to have no easily the class adjust soon, adjust to compare soon big;The sport is steady;Apt to realize automation;Combining can realize complicated automation work circulation;Have from the lubrication ability;Wear away small, the life span is long;The liquid presses a piece apts to realize in general use turn, standardizing, the easy to large quantity measures production.So, this designs of clip the tight way and then adopt the liquid press.

Key phrase:The square knife in bed in machine in CA6140; liquid presses to clip tight,;the craft work packs the design
