1、外文原文：Drill model and clampIntroduce That work piece must be located in going ahead opposite to safe location of cutter. Must score and then on work piece, clamp and on moving the location processing to need, before treating in this location. Think that a lot of peculiar work piece carries out the se

2、tting-out processing front, needing to be in progress to every part by drill model and the clamp, if but being casting or including forging, in order to ensure that work piece can be processed out, must be used for out a lineation, to ensure that deformation or appositions happened in sharpening rib

3、, the core to work piece. Drill model and the clamp need to ensure that work piece is correct combining with ability fixing，position and clamping. Drill model is such imply the diversity; clamp processing the process middle knife track. In reality, being only a cutter is a bore bit; drift and simila

4、r cutter ability carry out guiding. Therefore, drill model has used drill treating, furniture has been used for possessions other processes operation middle. The clamp is used for cutter device relative to localized union. Drill model and the clamp merit can divide into several aspect of the followi

5、ng： 1. Have cut down and have removed a little measurement and the working procedure assembling.2. The layman also may accurately fast grasp the cutting tool installment.3. The work piece assembling a part is gone to the lavatory especially, all work pieces are dismounted also seldom, and the delica

6、te job of crescent-shaped knife with long handle is removed.4. The part will realize mutual exchange, if work piece is unitary-relation fix to coming true in a fields words, the part.The bolt hole often has 1.5 mms to may possibly doubt that using drill model to process its accuracy to homogeneous 3

7、 mms pitches of score, reader. Must remember drill model is a fabrication but is accomplished, that being used for a lot of component creating drill model cost accurately is too big, to make propel surprised besides dextrally, is that the little mistake gathers moment assembling in it. Think that sc

8、rewing the body is beneficial to go and observing when, peculiar, it allows the careless setting-out and machine to touch it.1. Work piece location. Have indicated the object liberty degree in space, having three liberty degree to part for is that XX , YY , ZZ object are able to carry out axial disp

9、lacement along these axes; Still having three liberty degree is angle directions. They can go round a coordinate axis rotating. Liberty degree number is six. Think that work piece fixes the queen, its liberty degree must be eliminated, need with guarantee work piece rightness operation. Be as far as

10、 possible than make use of clamp guarantee work piece treating location. Apply it to possessions processing location, come to other clamp to ensure that processing location is to change it just now unless must use. If having necessary words, the new location clamp, must be processed to the previousl

11、y only row processing location.2. Work piece is clamped. Clamp location must be able to fight against cutting a force, clamp the strenuously necessary greater than work piece deformation force or destructive power. Grip taboo must can bear below work piece, in order to ensuring that this force is dr

12、illed a model or gripping the concrete frame on the machine tool. Think that drill touches a sum when the clamp is designed, clamp a device being designed that or can accurate provide the fastening motion force, and clamp a device being able to rapidly safe operationDrill model definitionDrill model

13、 is a location being able to ensure that the hole is drilled in work piece, expanding, mincing. Location clamping work piece in clamp device, the following being located in quenching steel axle bearing in drill model. If work piece structure is similar, drill model may be clamped on work piece. In m

14、ost of the cases, work piece passes drill model fastening motion, makes use of drill model to be to be intervened in and to be moved away rapidly for realizing work piece in the process of treating by the fleetness.Drill model may be to realize drill, expand for the quickest speed, the hole, comes t

15、rue and comparatively than the manpower treating hole is more accurate. Another merit is to use drill model to be able to not make a worker bring about hurt， Localized accuracy of hole. Not ensuring that depending on handling person, but come ensure that being to depend on drill model.Drill model ou

16、ght to be only rising being used to hide in, expand. It may possibly be winding drill machine displacement if being able to not fix on the machine, but the drill model spurring men at the lower levels on directly covers with. Drill model restricts and controls the cutter route directly.If processing

17、 middle include operations words such as bright metal, forming treating, vehicle，Ought to use a clamp. In the process of treating, the clamp not including peculiar guiding adjustments words uses drill model to be also OK.Representative drill model and clampProcess four holes in representative drill

18、model, in already one processing outside. Have an accurate treating centre on this work piece, be located in and the centre hole and the ultimate surface. Do not certainly need the circumference location going to control the encompassment hole cavity axis. Because of until it all is symmetrical rela

19、tive to that axle centre when every hole is processed. That this four bushes are used to control drill model being clamped in drill model plate, uses hand movement nut to go to clamp work piece, uses whose applets on the clamp.The representative clamp is a simple bright metal operation processing a

20、slot outside in work piece. Work piece is fixed two going to four Kong Hong in cardinal plane. Work piece is clamped on this location, the cutter is mounted quickly by apprises in the installation providing cutter installation or cutter allocation cutting a depth. The clamp must fix position opposit

21、e to the machine work piece, this reaches coming the slotting being to enter machine job stage by two the wedge head of the clamp bottom being made. That the clamp to inspect with the slot processing and processing a centre to T type bolt is safe.中文翻译：钻模与夹具介绍工件必须位于相对与刀具安全的位置上。然后在工件上必须划线，移动到需要加工的位置上，

22、并且在加工前夹紧在这个位置。当许多特殊的工件进行加工前，需要通过钻模和夹具对每部分进行画线，但如果是铸件或包括锻件，为了保证工件能被加工出来，必须对工件做出划线，以保证加强肋、型芯不发生变形或错位。钻模和夹具要结合起来才能保证工件正确的定位和夹紧。钻模是意味着加工过程中刀轨不同，夹具就不是这样。在实际中，只是刀具是钻头、绞刀和类似刀具才能进行导向。因此钻模用了钻加工，家具用于所有其它加工操作中。夹具用于刀具装置相对于定位的结合。钻模和夹具的优点能分成以下几方面：1) 减少和消除了一些测量和安装的工序。2) 非专业人员也可以准确快速地掌握刀具安装。3) 装配部分的工件更加方便，所有工件也很少拆装

23、，镗工的工作被消除。4) 零件将实现互换，如果工件是固定在一个领域的话，零件将实现单一化。螺栓孔经常有1.5mm到3mm的均匀螺距,读者可能会怀疑用钻模加工它的精确性。必须记住钻模是一次制造而成，用于许多元件精确制造钻模的费用是额外大的，此外，令人惊讶的是小小的错误聚集在它装配的时候。当螺距是特殊的时候，有利于去观察，它允许粗心的画线和机器碰它，1) 工件位置。表明了物体在空间的自由度，有三个自由度分别是XX、 YY、 ZZ物体能够沿着这些轴进行轴向移动；还有三个自由度是角度方向的。它们可以绕坐标轴转动。自由度的个数是六个。当工件固定后，它的自由度可能必须被消除，以保证工件正确操作的需要。要尽

24、可能的利用夹具保证工件的加工位置。将它应用到所有加工位置，除非必须用到其它夹具来保证加工位置是才换它。如果有必要的话，新的位置夹具，必须被加工到以前的加工位置才行。2) 工件夹紧。夹紧位置必须能够抵抗切削力，夹紧力必须大于工件变形力或破坏力。夹禁点必须在工件下面，以保证这个力被钻模或夹具体框架在机床上所能承受。当钻摸和夹具被设计时，夹紧装置被设计或能够准确提供夹紧力，并且夹紧装置能够快速安全的操作。钻模的定义钻模是一个能够保证孔在工件被钻、扩、绞的位置。在夹具装置夹紧工件的位置，在钻模中位于淬火钢轴承的下面。如果工件结构相似，钻模可能被夹紧在工件上。在大多数情况下，工件通过钻模夹紧，利用钻模是

25、为了在加工过程中实现工件被快速插入和快速移开。钻模可能是为了最快速度实现钻、扩、较孔，并且实现比人工加工孔更准确。另一个优点是使用钻模不会使工人造成伤害。孔定位的准确。不靠操作者保证，而是靠钻模来保证。钻模应该被只是用来钻、扩、绞孔。它如果在机器上不能固定的话，可能会绕着钻床移动而直接带动下面的钻模套。钻模直接限制和控制刀具的路径。如果加工中包括铣、成形加工、车等操作的话。应该使用夹具。夹具在加工过程中不包括特殊导向校正的话，用钻模也行。典型的钻模和夹具典型的钻模中，在一个已加工表面中加工四个孔。在这个工件上有一个准确的加工中心，并且位于中心孔和最终表面。没有必要去控制围绕孔腔轴线的圆周位置。因为直到各孔被加工时，它都是相对于该轴心对称的。这四个衬套被用于控制钻模被夹紧在钻模盘，用手动螺母去夹紧工件，使其紧贴在夹具上。典型夹具是一个简单的在工件表面加工槽的铣操作。工件被固定在基面下四个孔中的两个。工件被夹紧在这个位置上，刀具被紧贴在提供刀具安装或刀具定位切削深度的安装快上。夹具必须相对与机器的工件定位，这是通过把夹具底部的两个楔头做入机器工作台上的开槽来达到的。夹具对T型螺栓加工和加工中心槽来说是安全的。
