Changes the control box components to drill, to twist, attacks the silk drilling machine unit clamp newly to design
摘要
Abstract
本设计为拖拉机转向操纵箱零件钻基准孔工序的机床专用夹具设计并进行了夹具的三维造型。本道工序需要完成工件上的2-Φ14基准孔、1-Φ10孔以及工件侧面Z3/8”油孔的加工,设计中采用翻转钻模,通过夹具体上的分度装置依次到达安装工位,钻三孔工位,钻、攻Z3/8”油孔工位,完成工件的工艺内容。该设计理论依据充分,结构合理,能满足本工序的各项精度要求。
This design changed the control box components for the tractor to drill the datum hole working procedure the engine bed unit clamp to design and to carry on jig's three dimensional modelling. This working procedure needs to complete on the work piece 2- φ14 datum hole, 1- φ10 holes as well as work piece side Z3/8” the oil hole processing, in the design uses the turn over jig, arrives in turn through the jig body's on spacing device installs the location, drills three locations, drills, attacks Z3/8” the oil hole location, completes the work piece the craft content. This design theory basis is full, the structure is reasonable, can satisfy this working procedure each accuracy requirement.
由于拖拉机转箱操纵箱零件的加工批量很大,设计中参考了许多成熟的结构,本设计结构简单、操作方便,使用了大量的标准元件,大大缩短了本工序的辅助时间,一定程度上提高了劳动生产率,减轻了工人的劳动强度。同时具设计中也存在一些缺点,譬如,夹具体重量较大,不便于整体的运送;而且夹具装配后占用较大的面积,有待于进一步的改善。
Because hauls the turning point box control box components the processing batch to be very big, in the design has referred to many mature structures, this design structure is simple, the ease of operation, has used the massive standard components, reduced this working procedure non-cutting time greatly, in the certain extent raised the labor productivity, reduced worker's labor intensity. Simultaneously has in the design also to have some shortcomings, for example, the jig body weight quantity is big, is not advantageous for the whole shipping; Moreover after jig assembly, takes the big area, waits for in the further improvement.
本次设计利用Auto-CAD 、SolidWorks 2007等先进的辅助设计软件进行设计,结构明确,可视化效果很好。
This design using Auto-CAD, SolidWorks 2007 and so on advanced aided design software carries on the design, the structure is clear, the visualization effect is very good.

Living In A Big City
People all want to live in a big city instead of living in a small county or even a village.Why?Maybe city life is attractive with all its advantages and conveniences,for example a lot of supermarkets or shopping malls for us to easily buy what we need in our everyday life.And we can dine out if we don't have enough time to make dinner.With the expansion of the city,more and more people are flowing into the city,which also makes the city more and more crowded.So you could see traffic jams happening almost every day.There are also other aspects of the disavantages.
If you want to live in a big city,you will have to suffer the disadvantages when you benefit from all the advantages and conveniences.
我们的思维就像是照相机,但它所拍下的照片不仅仅是我们看到的,还包括我们感觉,听觉,嗅觉和味觉。我们用真正的相机时,在照片完成之前并向我们的朋友展示之前有许多工作要做。与此类似,我们要在记忆中永久保存一张照片也要做许多准备工作
一个良好的记忆力是大大有利于学习一门语言。当他是个孩子的时候每个人都会通过他所听到的来学会自己的语言,一些小孩子,比如那些在父母在国外生活的男孩和女孩们学习两种语言几乎和学习一种语言一样简单。但在学校里学习第二语言不是那麼容易,因为学生们很少有时间来学习它,他们正忙于其它方面的事情。
我们的意识相当於照相机,但它拍照不仅仅是我们所看到的,还有我们所感觉到的,听到的、闻到和尝到的。当我们用照相机拍摄真实照片的时候,在这张照片洗出来的时候有许多事要去做,还要准备拿给给我们的朋友欣赏。同样的方式,在我们永远记住一张图片的时候,我们有许多事情要做。
好的记忆对于语言的学习有很大的帮助。每个人都是通过记住他小的时候所听到的东西来学习语言的。而对于一些和父母生活在国外的男孩女孩们学习两种语言似乎跟学习一种语言一样简单。在学校学习第二种语言并不容易因为孩子们接触它的时间很少,况且他们还要忙于其他的科目的学习。
我们的大脑像一个照相机,但是它不但拍下我们看到的还会拍下我们感觉到的、闻到的和尝到的。当我们用真正的照相机照相之前,需要做很多准备工作才能去拍我们的好朋友。同理,要永远地在我们的大脑中记住一幅图像也需要做很多的工作。
