中 文 摘 要

随着社会的发展，液压系统有其独特的优点，因此被广泛地应用在各种场合。液压泵是液压系统不可缺少的组成部分，因此需要大批量生产，然而在大批量的生产过程中效率问题是一个急待解决的问题。通用机床加工适应性强但效率低，因此需要设计一种专用机床来解决效率问题。本次毕业设计就是要解决这一问题，设计一卧式双面镗床，其中进给系统我用液压滑台来支撑并提供动力，由于液压滑台尤其独特的优势，这样就可保证加工的质量。我们采用液压工作台和液压驱动的专用夹具，一次装夹可以同时加工四个工件，然后工作台移位进行下一工步，这样一次性加工出四个零件。这样既保证了加工效率又保证了加工质量 。
在设计中，为了降低成本我们尽量选用标准零部件，比如：床身、动力头…。根据零件的尺寸特点和工步安排，应该设计一专用的滑台和工作台、夹具。
这样，把各零部件按照一定的装配精度和装配要求装配好，效率问题就随之而解了。

Title  Combination machine tool design for processing the gear-pump holes                                                   
Abstract
With the development of society, the hydraulic system has its unique advantages, so it is widely used in various occasions. Hydraulic pump of the hydraulic system is an important part, but in large quantities , the efficiency of the production process is a pressing issue. Universal machine tool is adaptable ,but it has low efficiency. we need to design a special machine to solve the problem of efficiency. The graduation project is to solve this problem, the design of a two-sided horizontal boring machine, which feed system I use hydraulic slider to support and provide the impetus, as hydraulic slider particularly unique advantages, such assurances can be processed .The quality of our use of hydraulic table and hydraulic-driven special fixture, the fixture can be processed in four parts at the same time, and then shift to the next table step, this one-time processing four parts. This will ensure that the processing efficiency of the processing and quality assurance.
In the design, in order to reduce the costs as much as possible we have chosen the standard components, such as: Bed, dynamic head…and so on. According to parts of the size and characteristics of the further arrangements,I should be a design for the slider and workstations, fixture.
In this way, the various parts of the assembly in accordance with certain requirements of assembly and assembly accuracy, and efficiency problems is not a really problem.
