设计简介
摘 要
在机床上加工工件时，定位和夹紧的全过程称为“安装”。在机床上用来完成工件安装任务的重要工艺装备，就是各类夹具中应用最为广泛的“机床夹具”。
机床夹具的种类很多，其中，使用范围最广的通用夹具，规格尺寸多已标准化，并且有专业的工厂进行生产。而广泛用于批量生产，专为某工件加工工序服务的专用夹具，则需要各制造厂根据工件加工工艺自行设计制造。本设计的主要内容是设计铣床夹具
零件上往往都有各种不同用途和不同精度的孔需要加工。在机械加工中，孔的加工量所占比例较大，其中钻头、扩孔钻、铰刀等定尺寸刀具加工占相当多数。这时，除了要保证孔的尺寸精度外，还要达到孔的位置精度要求。在单件小批量生产中，用划线后找正孔轴线位置方法加工。在批量生产中一般都采用夹具。

Abstract
In the machine machining, positioning and clamping process called "installation". The machine used to complete the task of workpiece installation of process equipment, is an important fixture in the most widely used "the machine tool's fixture.
There are many kinds of the machine tool's fixture, among them, use the widest range of general fixture, size, and there has been more standardized professional factory production. And widely used in mass production, designed for a workpiece machining processes and special fixture service to the factory according to the workpiece machining process to design and manufacture. The design of the main content is boring and milling machine fixture design jigs, need to pump body Φ 52 holes on the left end fine machining milling.
Pump body parts are usually different purposes and accuracy of the hole machining. In machining, the hole of manufactured, among which the proportion of drilling, reaming, reamer, boring tools for size of such a sizable majority. At this time, except to ensure the accuracy of the size of the hole hole, but also achieve the position precision requirements. In single small batch production, use crossed for positive hole axis position after processing methods. In batch production in general by drilling and boring fixture, drilling fixture and diamond fixture, boring fixture and say, boring, boring set by drilling tools for processing guide can accurately determine tool and the relative position between the workpiece.
