摘要:夾具是機(jī)械加工不可缺少的部件,在機(jī)床技術(shù)向高速、高效、精密、復(fù)合、智能、環(huán)保方向發(fā)展的帶動(dòng)下,夾具技術(shù)正朝著高精、高效、模塊、組合、通用、經(jīng)濟(jì)方向發(fā)展。
該畢業(yè)設(shè)計(jì)任務(wù)是鉆削汽車前拖鉤φ17mm、φ13mm、Ra3.2粗糙度的兩個(gè)通孔。工件以臺(tái)階面、側(cè)面和圓弧面為定位基準(zhǔn),工件材料45#鋼,數(shù)量為中批量。由于該零件屬于中批量生產(chǎn),鉆孔精度有要求,因此設(shè)計(jì)一個(gè)專用的鉆床夾具,保證零件的加工質(zhì)量,提高加工效率。
本夾具采用移動(dòng)式結(jié)構(gòu)是為了工件在一次安裝中鉆兩較大的孔時(shí),可以極為方便地確定鉆套對(duì)刀具的位置,從而節(jié)省找正夾具的時(shí)間,減少鉆套與刀具的磨損。
完成鉆床夾具的所有設(shè)計(jì)后,用PRO/E進(jìn)行三維圖形的繪制,首先畫裝配圖,然后從裝配圖上拆畫零件圖,標(biāo)注相關(guān)尺寸及技術(shù)要求,最后進(jìn)行論文的撰寫、整理、修改完成該畢業(yè)設(shè)計(jì)。

Title Car ex- design for dragging along hook to drill a hole tongs
Abstract
The tongs is a machine to process an indispensable parts, at tool machine technique to the high speed, efficiently, nicety, compound, intelligence, environmental protection direction development of arouse under, tongs technique just toward the high Jing, efficiently, mold piece, combination, in general use and economic direction development.
The graduation design's task is two bores that drill to drag along to hook φ 17 mms, φ 13 mms and Ra3.2 roughnesses before paring a car.The work piece takes step noodles, on the side and arc noodles as to position basis, the work piece material is 45# steels, amount is medium batch quantity.That spare parts belongs to medium batch quantity production and drills a hole accuracy to contain request, therefore design drilling of an appropriation bed tongs, promise processing of spare parts quality, the exaltation processes an efficiency.
This tongs adoption ambulation type structure for the sake of work piece while drilling two bigger bores in a gearing, can extremely and expediently make sure to drill a set to the position that the knife has, save time of seeking the positive tongs thus, the decrease drills set and knife to have of wear away.
The completion after drilling all designs of bed tongs carries on drawing of two-dimensional sketch with AutoCAD, the painting assembles diagram first, then from assemble the diagram up dismantle painting spare parts diagram and mark related size and technique request, finally carrying on a compose, tidying up of thesis and modifying completion should graduate a design.
