镗Φ60孔夹具装配图
摘要
本文是对泵体零件加工应用及加工的工艺性分析，此外还对镗Φ60孔工序的加工设计了镗床夹具。
在机床上加工工件时，为了保证加工精度，必须正确安装工件，使其相对机床切削成形运动和刀具占有正确的位置，这一过程称为“定位”。为了不因受切削力、惯性力、重力等外力作用而破坏工件已定的正确位置，还必须对其施加一定的夹紧力，这一过程称为“夹紧”。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，但广泛用于批量生产，专为某工件加工工序服务的专用夹具，需要各制造厂根据工件加工工艺自行设计制造。因此，专用夹具的设计是一项重要生产准备工作，每一个从事加工工艺的工装设计人员，都应该掌握有关夹具设计的基础知识。

Abstract
In this paper, the application of pump parts processing and processing technology analysis, in addition to boring_60 hole process design boring fixture.
In order to ensure the machining accuracy, the workpiece must be installed correctly so that it occupies the correct position relative to the cutting forming movement and the cutting tool. This process is called "positioning". In order not to be subjected to cutting force, inertia force, gravity and other external forces to destroy the correct position of the workpiece has been set, but also must be applied to a certain clamping force, this process is called "clamping". The whole process of positioning and clamping is called "installation". The important process equipment used to complete the task of workpiece installation on the machine tool is the most widely used "machine tool fixture".
There are many kinds of jigs, but they are widely used in mass production. Special jigs are designed and manufactured according to the workpiece processing technology. Therefore, the design of special fixture is an important preparation for production. Every Tooling Designer engaged in processing technology should master the basic knowledge of fixture design.
