摘 要 本設(shè)計(jì)是車(chē)床撥叉零件的加工工藝及專(zhuān)用夾具設(shè)計(jì)。從零件的結(jié)構(gòu)外型分析,它的外型復(fù)雜,且不易加工,因此該零件選用鑄造件。它的主要加工面是孔、撥叉叉口兩端面和槽,在設(shè)計(jì)中采用先面后孔的原則,先以一個(gè)面加工出一個(gè)基準(zhǔn)面,然后,再以該基準(zhǔn)面加工相應(yīng)的孔。在后面的工序中,均以該孔為定位基準(zhǔn),加工其他部位,在整個(gè)加工過(guò)程中,分別采用了銑床、鉆床和鏜床。按要求設(shè)計(jì)了鏜孔專(zhuān)用夾具,采用一面兩銷(xiāo)定位。由于該零件的尺寸不大,所需的夾緊力不大。因此,夾緊方式都采用手動(dòng)夾緊,它的夾緊簡(jiǎn)單,機(jī)構(gòu)的設(shè)計(jì)更為方便,滿(mǎn)足夾緊要求。 關(guān)鍵詞: 撥叉,加工工藝,專(zhuān)用夾具,定位 The plectrum parts processing and special fixture Designs to the lathe of CA 6140 Abstract This design is a lather plectrum parts processing and special fixture designs. Appearance from the analysis of the structure of parts, it looks complicated and difficult process, the choice of casting parts. Its main processing side holes at both ends of fork surface and groove, used in the design after the first hole of the principle of surface, first with a surface of a base-level processing, and then base-level processing of the corresponding hole. Behind the processes, are the base of the hole for positioning, processing other parts of the body, in the whole process, namely the use of a milling machine, drilling and boring machine Required to design a special jig boring, using a two-pin position. Due to the size of the parts do not, the clamping force is not required. Therefore, the clamping means are manually clamping, clamping it simple, more convenient for the design of institutions to meet the requirements clamping.
