摘 要
制造業(yè)中尤其是機(jī)械制造業(yè)，在產(chǎn)品生產(chǎn)過程中按照特定工藝，不論其生產(chǎn)規(guī)模如何，都需要種類繁多的工藝裝備，而制造業(yè)產(chǎn)品的質(zhì)量、生產(chǎn)率、成本無不與工藝裝備有關(guān)。隨著不規(guī)則形狀零件在現(xiàn)代制造業(yè)中的廣泛應(yīng)用，如何保證這類零件的加工精度就顯得尤為重要。本文通過分析注油器油閥座零件的結(jié)構(gòu)特點(diǎn)和加工要求，制定了一套較合理的夾具設(shè)計，從而為保證該零件的加工精度將提供一種經(jīng)濟(jì)實(shí)用的工藝裝備，具有一定的實(shí)用價值。對于夾具設(shè)計來說，最重要的就是定位、夾緊方案的確定。通過對各種定位夾緊裝置的分析比較，選擇并組合了一套既能夠滿足加工要求的，又比較簡潔的裝置。同時，通過對一系列定位誤差和夾緊力的計算，驗(yàn)證了該零件的加工是可以保證其要求的精度的，它的加工誤差在規(guī)定的范圍內(nèi)。通過夾緊力的計算，也驗(yàn)證了零件在被夾緊的前提下，它受到的夾緊力也并不大，滿足夾具設(shè)計所要求的既要保證一定的夾緊力不使工件在加工過程中發(fā)生位移，但同時又不能過大致使工件發(fā)生變形。

Abstract
In the manufacturing sector in particular, mechanical manufacturing, products in the production process in accordance with the specific process, regardless of their scale of production, requires a wide range of process equipment, manufacturing and product quality, productivity, cost and process all the relevant equipment. With the irregular shape of the parts in the modern manufacturing industry in a wide range of applications, how to ensure that this type of precision machining of parts is particularly important. Through analysis of the oil-seat oiling parts of the structure and characteristics of the processing requirements of the development of a more reasonable fixture design, so as to guarantee the precision machining of parts will provide an economical and practical technology equipment, has some practical value. The fixture design, the most important thing is positioning, clamping identification program. By targeting a variety of clamping devices analyzed and compared, and choose a combination of both to meet the demands of processing, and the relatively simple device. At the same time, through a series of clamping force and positioning errors of calculation, parts of the verification process is required to ensure its accuracy, its error in the processing requirements. Clamping force through the calculation, but also to verify the parts in the clamp on the premise of it by the clamping force is not large, the fixture design to meet the required not only to ensure a certain degree of clamping force not to work during processing Shifted, but at the same time, not too much work led to deformation occurred.
Key words: technology equipment, fixture design, positioning, clamping
