摘要
錫林結(jié)合體是梳棉機(jī)上的一個(gè)關(guān)鍵零部件，它的加工質(zhì)量直接影響到梳棉機(jī)的工作穩(wěn)定性，使用壽命等性能。因此其加工精度要求較高，尤其是軸承蓋與軸承座的結(jié)合面及軸承孔的精度有很高的要求，這些精度的保證是本工藝規(guī)程的難點(diǎn)，同時(shí)也是重點(diǎn)。本次設(shè)計(jì)針對(duì)錫林結(jié)合體的自身特點(diǎn)及生產(chǎn)廠家現(xiàn)有的設(shè)備來編制工藝規(guī)程及相關(guān)專用夾具的設(shè)計(jì)。內(nèi)容主要包括：毛坯的確定、定位基準(zhǔn)的選擇、工序余量確定等。

關(guān)鍵詞：軸承結(jié)合體  工藝規(guī)程  專用夾具

Abstract
The Xilin bearing combine is an important part of the card . Its machining quantity affects the working stability and the service life of the card. So it machining accuracy have higher request. Particularly the combine face of the bearings cover and the bearing body andthe bearings bore have the very high request. The assurance of these accuracies is the keytechnique and difference of this process rules. To preferring the characteristics of he connecting rod of the United States races car and the condition of the machining etc, this craft rules are well designed. The contents mainly includes: the semi-finished product really settles, the choice of the fixed position basis, the part preface remaining measure assurance etc..

Key words:  bearing combine    machining rules    clamp
