【正文】 xibility and fixture can be divided into : special fixture, the fixture binations, the standard fixture, high flexible fixture. Flexible fixture on different parts of their high adaptability and the few lowcost replacement for the characteristic. Forms can transform the structure of the flexible fixture can be installed with the change of structure ponents (such as needle cheek plate, Multichip ponents and flake cheek plate), a nonstandard work piece gripper or clamping elements (for example : mencement standard with a clamping fixture and mobile ponents fixture supporting documents), or with ceramic or hardening of the intermediary substances (such as : Mobile particle bed fixture and heat 13 fixture tight fixture). To production, the parts were secured fixture, the need to generate clamping function, its fixture with a few unrelated to the sexual submissive steps: According to the processing was part of that foundation and working characteristics to determine the work piece fixture in the required position, then need to select some stability flat bination, These constitute a stable plane was fixed in the work piece fixture set position on the clampprofile structure, all balanced and torque, it has also ensured that the work features close to the work piece. Finally, it must be calculated and adjusted, assembly or disassembly be standard fixture ponents required for the position, so that the work piece firmly by clamping fixture in China. In accordance with this procedure, the outline fixture structure and equipped with the planning and recording process can be automated control. Structural modeling task is to produce some stable flat bination, Thus, these plane of the work pieces clamping force and will fixture stability. According to usual practice, this task can be humanmachine dialogue that is almost pletely automated way to pletion. A manmachine dialogue that is automated fixture structure modeling to determine the merits can be conducted in an anized and planning fixture design, reduce the amount of the design, shortening the study period and better distribution of work conditions. In short, can be successfully achieved significantly improve fixture efficiency and effectiveness. Fully prepared to structure programs and the number of material circumstances, the pletion of the first successful assembly can save up to 60% of the time. Therefore fixture process modeling agencies is the purpose of the program have appropriate documents. 。依據(jù)這樣的程序,夾具的輪廓結(jié)構(gòu)和裝合的規(guī)劃和記錄過程可以進行自動化控制。這種情形正迫使許多公司更多地致力于廣泛的合理化改革和前面提到過情況那樣裝配自動化。 8 五 自動夾具設(shè)計 用做裝配設(shè)備的傳統(tǒng)同步夾 具把零件移動到夾具中心上,以確保零件從傳送機上或從設(shè)備盤上取出后置于已定位置上。這是因為局部效應(yīng),這像未加工表面上的已硬化層,這效應(yīng)是由前面的切削引起的工件硬化造成的。 由于刀具表面上的應(yīng)力分布不均勻,切屑和前刀面之間滑動接觸區(qū)應(yīng)力,在滑動接觸區(qū)的起始處最大,而在接觸區(qū)的尾部為零,這樣磨蝕性磨損在這個區(qū)域發(fā)生了。當要加工廣泛的工件材料時,Trent 已經(jīng)論述過測定高速鋼刀具的切削溫度及溫度分布的方法。然而切削速度的增加,傳導到工件上的熱 的數(shù)量減少而這又增加主變形區(qū)中的切屑溫升。 6 三 切削參數(shù)的改變對切削溫度的影響 金屬切削操作中,熱是在主變形區(qū)和副變形區(qū)發(fā)生的。一般來說,工件材料越硬,速度越低。另方面,許多零件靠較粗的生產(chǎn)加工工藝提高其一般表面形狀,而僅僅是在需要高精度的且選擇過的表面才進行機械加工。 機械加工在知道過程中具備兩方面。 4 第 4 章 致謝 四年的時光,彈指一揮間,恍若白駒過隙,從出來到銅陵的完全陌生到四年后的漸漸熟悉喜歡并愛上這座城市,銅陵很小但很溫馨像家一樣能給人溫暖,但一切像夢一樣被畢業(yè)驚醒。在破碎之后還需要進行篩分處理,將破碎后的銅基 粉倒入篩分機篩分出不同目數(shù)的銅基粉,在篩分之后按廠家提供的發(fā)貨要求對篩分后的銅粉進行合批處理,知道合批后的檢測數(shù)據(jù)達到廠家出廠的發(fā)貨要求為止。 銅粉廠的實習經(jīng)歷 在剛進公司的時候,我被安排到了銅粉廠的生產(chǎn)車間 1 號線去進行操作員實習,主要熟悉銅粉加工工序及設(shè)備的操作,了解 1 號線的銅粉生產(chǎn)全過程。 公司的規(guī)劃和前景 公司的口號是“卓之為專,成之為信”,喻意卓成,設(shè)有技術(shù)部、營銷部、資產(chǎn)綜合管理部、電子商務(wù)部、品質(zhì)部、檢測部等。 學 號 0910111040 畢業(yè)設(shè)計(前期材料) 學生姓名 李開兵 院 別 機械工程學院 專業(yè)班級 09 機械設(shè)計制造及其自動化 2 班 指導教師 吳強 林 云志 二 0 一 三 年 六 月 目錄 第一部分(實習報告) 第 1 章 公司簡介 ………………………………………………………………… ..………… ...1 第 2 章 經(jīng)過實習 ……………………………………………………………………… ..…… ...1 第 3 章 實習總結(jié) ……………………………………………………………………………… .4 第 4 章 致謝 ………………………………………………………………………… .................5 第二部分(中文翻譯) 一 緒言 ……………………………………………… ………………… ..…………………… ...6 二 基本機械加工 參數(shù) ……………………………………………………………………… .....6 三 切削參數(shù)的改變對切削溫度的影響 ……………………………………………………… .7 四 刀具磨損 …………………………………………………………………………………… .8 五 自動夾具設(shè)計 ……………………………………………………………………………… .9 第三部分(外文原文) I.
