夹具中的夹紧构造应满足哪些要求!常用夹紧机构有几件大类

法兰盘只是一个统称,通常是指在一个类似盘状的金属体色的周边开上几个固定用的孔用于连接其它东西.它的作用是连接及传动.
这东西在机械上应用很广泛,所以样子也千奇百怪的,只要像就是叫法兰盘.
还有,名字是来源于英文flange~~~~~~

基础要求：
1、3轴定位,固定牢固；
2、定位基准安全、可靠、方便装夹；
3、夹具结构简单、易于安装与拆卸；
4、夹具坚固、安全；
5、一次装夹可以尽可能完成多个面的连续加工；
6、夹具精度高,强度好；

1.根据产品形状设计夹持,考虑快速装卸及夹持力
2.根据加工方法避开刀具,轨迹避免干涉,
先想到这里

是这样：零件加工欠定位决不允许,但过定位在一些场合下是允许的.
具体到你的问题：需要限制的3个自由度你已经明确,如果你增加限定的自由度和前述没有重复,则是允许的.举个例子：加工需要限定X转、Y转、Z平,你如果又限定了Z平,不允许；若限定了Z转,没问题.

最好先车外形,这样所有的圆都能有很好的同轴度,然后上铣床,再以fai80来定位夹紧铣两个缺面和钻孔,当然铣面和钻孔的时候,先找正fai108.这种零件的外形很简单,不需要设计夹具,镗一个软爪就可以了. 位置度0.15算是很松 的要求了,现在的稍微好一点的铣床都能达到.通过车保证同轴度来间接保证位置度,一点压力没有.

铸件主要是行腔定位,一次完成两个孔的加工,要用到加工中心的
如果没做过 那关键问题是孔径质量与型位公差了

很高兴能够在这里回答你的问题,应该为：
We will monitor the wear of the fixture,and there is not qualified when * *,repair or replace the fixture

限制是三个.还有X移动、Y移动和一个旋转没限制.

通常来说,电工实验室中的电流表不能改装成电压表,因为这些表所用的表头的灵敏度较低,不适合改装成电压表.
内接法和外接法指的是指同时用电压表、电流表测某一负载的电流和电压的接法 .
内接法指电压表和负载并联,然后再与电流表串联.
优点是电压测量不存在系统误差,但电流表的测量结果存在系统误差.
外接法指电流表先和负载串联,然后再整体与电压表并联.
优点是电路测量不存在系统误差,但电压表的测量存在系统误差.

According to the original material to clamp the mouth parts activities machining process planning and special fixture design. Through the design and study of manufacturing activity, a whole, the panorama of understanding and grasp, to master the basic rules of the metal cutting process, and master the basic knowledge of mechanical processing, can choose processing method and machine tool, cutting tool, fixture and processing parameters, have the ability of making process planning and control of the machine machining precision and surface quality of basic theory and basic knowledge, preliminary analysis and solution of the ability of the process on site. By using UG design parts, learned about the processing parts for the use of equipment, tooling and machine cutting movement for process planning design, including the blank, and determine the selection, the process route, machinery processing etc, and make the process card.

能详细一点吗?
加工中心 单件生产是不用考虑的
数控铣 数控车 数控折弯 都不一样的
你一篇论文全部涵盖?
建议你 从某种加工方式下手 比较普通和数控的差异
加工精度、成本、零件的运用场合 等
比如成本 ——产量达到多少 使用数控 以及专用夹具有优势 反之 应该用普通加工

1) bending operators enhance the quality awareness,strengthen self-control defective production,outflow;
2) pump mounting plate welding fixture has been improved to increase the function of positioning Goggles (pictured),put an end to this bad relapse.

A肯定

个人建议用70系列的铝材好点.硬度高.不容易变形.60系列的一般软一些.

30的圆,用菱形销（削边销）定位,可以避免过定位.菱形销长轴垂直于纸面.还需轴向定位（可以用37大圆的端面,等）

My current work introduction

I am now responsible for clamps,ME and other 191 work center products.These products demanding is getting down,and quality is more stable,so the improvement space of COQ is small,what we improved is the introduction of G product,As the chip test rate is low,and it is still in analysis,but it is the direction for G product to reduce the cost.There are something need pay more attention when transition:
Straight pass rate. Un-qualified rate of Top 3,Chip test rate
To compare with normal product and have some analysis
Compare of COQ
Risk analysis
Checking and revision of test standard
C product:need protect and maintnance of fibre-optical.Glass head fibre optical has been claimed many times,although customers has some unproperly operation,but we still need process mapping to evaluate
Other products need the verify for project change,RMA analysis and customers claims.
Hope the company has a prosperous business this year,and to be the best ones of the industrial.

立铣.1压板,2定位板3.4.6螺栓5弯板【与压板平行』.抱歉没有画图工具,整个画面视为弯板立面

将弯板校正固定在工作台上,初装时将2放在工作台3先不要旋紧,4装夹工件不要旋紧,压板将工件固定,旋紧4.2,以后只松4.6装卸工件即可.

在夹具中,用一个平面对工件的平面进行定位,平面内不在一条直线的三个点,是定位点,限制三个自由度.分别是,垂直于平面的移动；除了在平面上转动的其它两个转动,一共3个自由度被限制.

工件是否完全定位,理论上应该限制六个,完全定位,但是实际操作中限制3,4,5,6情况都有.

其依据是需要约束程度.比如车床卡盘其约束程度是百分之一百,不允许有任何与卡具之间的相对运动.以上属于全定位.欠定位,比如台钳,其正反两面定位很好,但是两侧则有移动的可能.过度定位是约束点选择过多的意思.现代卡具基本不会出现过度定位的设计.

原理误差是由于采用了近似的加工的运动轨迹而产生的误差

第二个是菱形销
没有过定位 只限制了x移动自由度 但是和第一个销配合 这个限制 转化为了 对z轴的转动
所以总的来说 菱形销只限制了z的转动

“工装”即工艺装备:指制造过程中所用的各种工具的总称.包括刀具/夹具/模具/量具/检具/辅具/钳工工具/工位器具等.工装为其通用简称.
故工装可意译为work tool.
夹具,可翻译为workholder、fixture、clamp.

1、先确定基准；
2、确定个零件的位置；
3、下笔绘画；
4、标注（尺寸、形位公差）
5、局部视图.
6、剖面线
7、技术要求及标题栏（明细栏）

主要看你加工几个面
加工5个面就是5个自由度不动.其他的差不多,只要不过定位就行.

本机床的使用方法：　　
a、按照被剪材料的厚度,调整刀片的间隙.
b ．根据被剪材料的宽度调整靠模或夹具.
C、机床操作前先作 1 — 3 次空行程,正常后才可实施剪切工作.
【The usage of the machine：】
a Adjust the blade clearance according to the thickness of cut material, .
b Adjust the profile modelling or fixture according to the width of the cut material.
c Before operating the machine tool,please perform noncutting stroke for 1-3 times. The implementation of the shearing work is only feasible when everything goes well.

夹具具有质量,不可忽略,会影响实验量的转动惯量.夹具随着球摆动,大部分在球与质心的连线上,只有少部分在球的一头,因此,转动惯量可以忽略.

Fixture's center of gravity is low,
is steady and reliable,
Don't easy to overset in work.

就用工厂里最常用的万能分度头+尾座+立式铣床（X52、X52K等）就搞定.分度头上四爪,夹住一端方头,另一端用尾座的顶尖顶住.旋转分度头调好45°角度.就OK了.铣好一边后,旋转180°,铣另一边.

Fixed processing object used in the mechanical manufacturing process,so that possession of the correct position to accept the construction or installation,testing,also known as the fixture (Qi ǎ J job).In a broad sense,any step in the process,used to rapidly and conveniently,safely installed device of workpiece,are referred to as the fixture.For example,welding fixture,test fixture,jig,fixture etc..The fixture is the most common,often referred to as the fixture.In the processing machine parts,requirements for the size,shape and surface and other mutual position precision,so that the workpiece surface can meet the provisions of drawings,the workpiece before processing must be installed (location),to (clamp).The fixture is usually composed of positioning element (determine the correct position of a workpiece in the fixture,clamping device),tool guide element (determine the tool and workpiece relative position or direction guiding tool),dividing device (machining,the workpiece can be completed in a number of positions in the installation of a rotary indexing device and linear motion indexing device two class),connected component and fixture (jig base).
