摘要
　　該課題主要是研究液壓系統(tǒng)及電器控制電路設(shè)計(jì)、相關(guān)液壓元件的選用和圖紙繪制。而液壓系統(tǒng)的工作原理在本課題中主要通過(guò)液壓滑臺(tái)的動(dòng)作循環(huán)來(lái)實(shí)現(xiàn).液壓動(dòng)力滑臺(tái)是液壓動(dòng)力組合機(jī)床最主要的通用部件之一，是完成刀架切削運(yùn)動(dòng)和進(jìn)給運(yùn)動(dòng)的動(dòng)力部件。它的質(zhì)量以及控制原理直接關(guān)系到零件的加工質(zhì)量。液壓動(dòng)力滑臺(tái)由滑臺(tái)、滑座、油缸三部分組成.油缸固定在滑座上，活塞桿則固定在滑臺(tái)的下面?；突_(tái)配置山-矩形導(dǎo)軌?；_(tái)在滑座上的移動(dòng)，借助于液壓站打出的壓力油通入油缸前腔或后腔來(lái)實(shí)現(xiàn)的。滑臺(tái)的工作速度則通過(guò)調(diào)整節(jié)流閥進(jìn)行無(wú)級(jí)調(diào)速?；_(tái)的各種工作循環(huán)由專(zhuān)門(mén)的液壓系統(tǒng)配以相應(yīng)的電氣及液壓擋鐵來(lái)實(shí)現(xiàn)。該課題完成后可為組合機(jī)床提供平穩(wěn)、可靠的進(jìn)給運(yùn)動(dòng)動(dòng)力部件，從而來(lái)保證零件的加工質(zhì)量。

The design of the hydraulic power sliding table

ABSTRACT
　　This theme is mainly study hydraulic system and electric control electrocircuit design, the selection of the hydraulic components and the paper drawing .In this theme, the working principle of the hydraulic system is realized by the operation cycle of the hydraulic power sliding table. Hydraulic power sliding table is one of the most universal components of the modular machine tool. It can finish the cutting movement and feed movement of the tool post . Its quality and control theory have something to do with the working quality of the parts directly. Hydraulic power sliding table is composed of sliding table, saddle and oil cylinder. Oil cylinder is fixed on the saddle and piston rod is fixed under the sliding table. The sliding table and the saddle set up E-rectangular guide way. The removal of the sliding table is depended on which the pressure oil from the hydraulic station flows into the front space or the back space of the oil cylinder. The working speed of the sliding table carries on stepless speed changing through adjusting throttle valve. All kinds of the working circulation of the sliding table is finished by special hydraulic system setting up corre..
