閥腔的加工工藝規(guī)程及夾具設(shè)計(jì)【銑上端面夾具、閥腔鏜100孔夾具含兩套夾具】
摘 要
本次設(shè)計(jì)內(nèi)容涉及了機(jī)械制造工藝及機(jī)床夾具設(shè)計(jì)、金屬切削機(jī)床、公差配合與測(cè)量等多方面的知識(shí)。
閥腔零件的工藝規(guī)程及銑工件上端面及鏜100孔夾具設(shè)計(jì)是包括零件加工的工藝設(shè)計(jì)、工序設(shè)計(jì)以及專(zhuān)用夾具的設(shè)計(jì)三部分。在工藝設(shè)計(jì)中要首先對(duì)零件進(jìn)行分析，了解零件的工藝再設(shè)計(jì)出毛坯的結(jié)構(gòu)，并選擇好零件的加工基準(zhǔn)，設(shè)計(jì)出零件的工藝路線；接著對(duì)零件各個(gè)工步的工序進(jìn)行尺寸計(jì)算，關(guān)鍵是決定出各個(gè)工序的工藝裝備及切削用量；然后進(jìn)行專(zhuān)用夾具的設(shè)計(jì)，選擇設(shè)計(jì)出夾具的各個(gè)組成部件，如定位元件、夾緊元件、引導(dǎo)元件、夾具體與機(jī)床的連接部件以及其它部件；計(jì)算出夾具定位時(shí)產(chǎn)生的定位誤差，分析夾具結(jié)構(gòu)的合理性與不足之處，并在以后設(shè)計(jì)中注意改進(jìn)。
關(guān)鍵詞：工藝、工序、切削用量、夾緊、定位、誤差。
The planning process and fixture design
Abstract
The design involves the mechanical manufacturing process and machine tool fixture design, metal cutting machine tools, tolerance, coordination and measurement, and many other aspects of knowledge.
Parts of the valve cavity on the milling process planning and design of 100 hole boring fixture design and end including machiningprocess design process design and fixture three. In the process of design should first understand the analysis of parts, parts of the process to design a blank structure, and choose the good components the processing datum, designs the process routes of the parts; then the parts of each labor step process size calculation, is the key to decide the craft equipment and the cutting process of the various design parameters; then a special fixture, the fixture selection for the various components of the design, such as connecting parts positioning elements and clamping elements, guide element, fixture and machine tool and other components; positioning error is calculated when the fixture, analysis the rationality and shortcoming of fixture structure, improve and design in later.
Key words: process, process, cutting parameters, clamping, positioning, error.
