A锁架零件图
摘要
于产品生产而言，夹具用于夹紧，生产之中玩不可少的一种工具。使用夹具之处相当之多，所获经济价值高，不需太多的组成零部件。目前的工件千变万化，很多夹具已经无法再次使用彼时有此，对专用夹具设计成为重要之事。对其开展设计之时，首先要肯定如何对零件予以定位，此后设计夹紧装置，并且给出夹紧方案，接着对夹具剩余部分开展设计。
此次所设计的专用夹具，生产工件为锁架，需钻加工孔Ф8，依据老师所交于的图纸，设计夹具，编写工艺，清楚此工件作何用，分析产品的工艺。按照设计内容，此夹具为机床夹具，生产之时务必确保其精度，效率务必高，另外操作之时需便利。
最开始设计，览阅相当之多和本次设计有关联的资料，可将图纸看明白，清楚工件的构造，另外分析其工艺，予以肯定所用粗基准、精基准，将其生产之时所需余量以及坯料之规格予以肯定，此后方可编写出工件的生产工艺，将每道工序之中切削用量以及工时予以确定，此后设计符合本次要求之夹具。

Abstract
In terms of product production,the fixture is used for clamping and plays an indispensable tool in production.There are quite a lot of places to use the fixture,which has high economicvalue and does not need too manycomponents.At present,theworkpieces are ever-changing,and manyjigs can not be used again,which isveryimportant for the design of special jigs.Whenwe design it,we should first confirm howto locate the parts,then design the clamping device,and give the clamping scheme,then design the rest of the fixture.
The special fixture designed this time,the productionworkpiece is the lock frame,and the machining holeФ8 needs to be drilled.According to the drawing submitted bythe teacher,design the fixture,prepare the process,knowwhat theworkpiece is used for,and analyze the product process.According to the design content,the fixture is a machine tool fixture,which must be ensured to be accurate,efficient and convenient for operation.
At the beginning of the design,you can read a lot of materials related to this design,see the drawings clearly,understand the structure of theworkpiece,analyze its process,confirm the used coarse and fine benchmarks,and confirm the required margin and the specification of the blank at the time of production.Thenyou canwrite out the production process of theworkpiece,and the cutting amount andworking hours in each process Confirm,and then design the fixture that meets the requirements of this time.
