閥腔工藝規(guī)程制定與夾具設(shè)計
摘 要
本次設(shè)計內(nèi)容涉及了機械制造工藝及機床夾具設(shè)計、金屬切削機床、公差配合與測量等多方面的知識。
閥腔零件的工藝規(guī)程及銑工件上端面夾具設(shè)計是包括零件加工的工藝設(shè)計、工序設(shè)計以及專用夾具的設(shè)計三部分。在工藝設(shè)計中要首先對零件進(jìn)行分析,了解零件的工藝再設(shè)計出毛坯的結(jié)構(gòu),并選擇好零件的加工基準(zhǔn),設(shè)計出零件的工藝路線;接著對零件各個工步的工序進(jìn)行尺寸計算,關(guān)鍵是決定出各個工序的工藝裝備及切削用量;然后進(jìn)行專用夾具的設(shè)計,選擇設(shè)計出夾具的各個組成部件,如定位元件、夾緊元件、引導(dǎo)元件、夾具體與機床的連接部件以及其它部件;計算出夾具定位時產(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 end milling process planning and fixture design is a design 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.
