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 middle include operations words such as bright metal, forming treating, vehicle，Ought to use a clamp. In the process of treating, the
