摘要

螺栓拉伸技術(shù)可以對工程用的螺栓進(jìn)行緊固和拆卸，可以拉緊螺栓達(dá)到預(yù)定載荷，廣泛的應(yīng)用與大型設(shè)備的螺栓裝載上。液壓拉伸器是液壓技術(shù)領(lǐng)域新近出現(xiàn)的工程設(shè)備它具有控制好、快速、安全、精確、耐用、維護(hù)少等優(yōu)點(diǎn)，適合嚴(yán)格的檢查和測定標(biāo)準(zhǔn)場合。
參考國內(nèi)外工程師對液壓拉伸器的研究成果，本文根據(jù)拉伸器拉緊原理，對多個(gè)液壓系統(tǒng)方案進(jìn)行比較，選擇并計(jì)算，根據(jù)計(jì)算數(shù)據(jù)選定了適合本次設(shè)計(jì)的液壓系統(tǒng)方案，我繪制了系統(tǒng)的總裝配圖，主要部件圖，并編寫了設(shè)計(jì)說明書。

ABSTRACT

The bolt draws technology can fasten and dismantle the bolt, it can strain the bolt reach the load of booking, and extensively used for fasten and dismantle of the device is the industry equipment of the technological field of the hydraulic pressure which appears recently. It has the advantage of good control, fast, safety, exactitude, wear well, little support etc, which suits the strict check and mean sure the standard situation.
Consult and draw lessons from the research results to the hydraulic pressure drawing device of domestic and international engineer, the foundation drawing device of the this text draws the urgent principle in advance, then compare systematic scheme of a lot of the hydraulic pressure designed this time according to the data of calculating. According to the selected systematic scheme of hydraulic pressure, I was drawn the total installation diagram of the system, the main spare part picture and written the design instruction.
