摘要
此次毕业设计任务是对3L-10/8空气压缩机曲轴零件的机械加工工艺、夹具的设计,在曲轴零件的加工工艺过程中轴与轴中心线之间要有位置要求, 以毛坯轴两端定位先加工两中心孔,以两端中心孔定位再粗、精加工各轴的表面,然后以粗、精后的两轴径定位钻螺纹、铣键槽和铣曲拐端面,采用专用夹具加工两斜油孔,最后粗、精磨各轴。
在夹具的设计过程中,主要以V形块和支承板来定位,靠直压板和弹簧来夹紧,钻拐径两孔应采用长型快换钻套,在钻拐径倾斜的孔时采用平面倾斜的夹具体,在钻拐径倾斜的孔时使用的是卧式钻床,铣面时2个V形块与铣刀不能干涉,因此V形块高度要降低,夹具设计要方便、简单。
关键词曲轴,加工工艺,夹具设计。
ABSTRACT
This graduation project duty is to the 3L-10/8 pressor ponents machine-finishing craft, the jig design, between the ponents processing technological process middle axle and the axle must have the position request ,processes two center bores first by the semifinished materials axis both sides localization ,by both sides center bore localization again thick, precision work various axes after thick, the essence two axle diameter localization drills the thread, the keyseat and the mill crank end surface.,uses the unit clamp to process two slanting oil holes, finally thick, correct grinding various axes.
In the jig design process, mainly locates by V shape block and the support plate, depends on the straight clamp and the spring clamps, drills turns diameter two to be supposed to use long trades quickly drills the wrap, when drills turns the diameter incline hole uses the plane incline the jig body, when drills turns the di
