中 文 摘 要

隨著社會的發(fā)展，液壓系統(tǒng)有其獨特的優(yōu)點，因此被廣泛地應(yīng)用在各種場合。液壓泵是液壓系統(tǒng)不可缺少的組成部分，因此需要大批量生產(chǎn)，然而在大批量的生產(chǎn)過程中效率問題是一個急待解決的問題。通用機床加工適應(yīng)性強但效率低，因此需要設(shè)計一種專用機床來解決效率問題。本次畢業(yè)設(shè)計就是要解決這一問題，設(shè)計一臥式雙面鏜床，其中進給系統(tǒng)我用液壓滑臺來支撐并提供動力，由于液壓滑臺尤其獨特的優(yōu)勢，這樣就可保證加工的質(zhì)量。我們采用液壓工作臺和液壓驅(qū)動的專用夾具，一次裝夾可以同時加工四個工件，然后工作臺移位進行下一工步，這樣一次性加工出四個零件。這樣既保證了加工效率又保證了加工質(zhì)量 。
在設(shè)計中，為了降低成本我們盡量選用標準零部件，比如：床身、動力頭…。根據(jù)零件的尺寸特點和工步安排，應(yīng)該設(shè)計一專用的滑臺和工作臺、夾具。
這樣，把各零部件按照一定的裝配精度和裝配要求裝配好，效率問題就隨之而解了。

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.
