1. Introduction 介绍
The intent of this standard is to specify Webasto Roof Systems requirements for design, build, certification and approval of gauges and check fixtures. This in not an all inclusive
listing. OEM customer standards will also apply to gauges and check fixtures for end item parts.
此标准意在阐述韦巴斯特关于夹具和检具在设计，制造认可中的系统要求。这个目录并未包含全部的标准。OEM客户的标准同样适用于成品零件的夹具和检具。
Gauges and check fixtures are a vital element to our quality management system. They are used to confirm dimensional conformance of parts and assemblies to facilitate effective process control. Every consideration must be given to assure they meet the following fundamental requirements:
夹具和检具是我们的质量管理系统中的一个重要元素。他们用来确保零件的尺寸和装配一致性以使程控更加有效。为保证符合根本要求,以下每一个要点都需要考虑到。
Accessible features which allow the user to readily check all specified part features in a reasonable amount of time without undue effort.
设计概念应考虑操作者的人机工程学、被测零件的装和拆的容易度，使用户在合理的时间内勿需过度的努力就可以很容易检查到所有指定部份的特征。
Accurate and durable locating points and part holding features to attain maximum repeatability and reproducibility error.
准确和耐久的定位点和部份需要可以获得最大的重复性和再现性误差特性。
Workmanship and construction to a standard that ensures durability and stability for continued use in a plant environment for the life of the part.
工艺和结构要做到可以保证在一个工厂环境内持续使用,零件的耐久性和寿命要有一个稳定的标准.
This WRS standard shall be adhered to for all gauge and check fixtures
所有夹具和检具都将遵守这个WRS 标准
Deviation from this standard requires prior written approval fromWRS.
如与这个标准有偏差, 需要预先从WRS处取得书面同意
Design approval shall not constitute a waiver for guarantee of the responsibility for any gauge purchase by WRS. An approved gauge design does not constitute a certified or approved gauge.
设计认可不会构成WRS放弃购买任何测量仪为责任的保证。检具设计的批核不构成被保证或批准的检具.
It is the sole responsibility of the gauge and check fixture construction source to assure that the revision of specification information provided matches the part number and revision level indicated by the WRS purchase order.
必须确保夹具和检具结构的规格数据版本符合WRS订单上所提供的零件号码及修正标准
Design设计
2. Gauge and fixture design approval is required by WRS Quality prior to Build. This approval will be in the form of signatures on the
WRS 质量需要在建造测量仪和装置前取得设计认同。这认同将在以署名形式签在Fixture Design Sign Off Sheet 表格上
3. All Designs are the property of Webasto Roof Systems. A copy of the design will be provided following design approval.
所有设计是Webasto 的财产。一份设计的付本将附着其设计批核
4. When clamps and/or swing templates are sued, the base must protect and contain them in open position.
当要用到夹钳或者旋转卡板时, 确保每个检具零件在其任何活动位置上都不会超出检具的基座
5. Gauge and Fixture base construction type: Cast aluminum or aluminum plate with supporting feet or legs are required.
6. 夹具和检具底座的可以使用铸铝或铝板材，需要配有支脚或支架。
7. Datum schem e must reflect part specifications. All net surfaces and datum?s are to be made from hardened steel and mounted to a separate base whenever possible. All nets and datum?s must be identified.
基准设计必须反应零件规范。所有网面和基准要由硬化的钢制造出来同时在可能的情况下安在一个单独的基准上。所有网面和基准必须可被辨认出来的.
8. Flush checks are to be machined at maximum and minimum.
Flush checks 是量度平滑/平顺的工具, 须要打磨出最高点及最低点共最小两件. 即flush check max 平碰被量度的物件是没有不平滑平顺, 而同样flush check min 平碰被量度的物件也没有不平滑平顺, (想象三只打麻雀牌放在一起比较平顺度) 用机器制造在最大值和最小值的齐平检查工具
9. Go/No-Go size pins to be put on the opposite end of location pins whenever possible.
通止规在可能的情况下要放在定位针的两边的相反方向末端
10. Hardened and ground pins for whole location checks are to be sized to 100% GD&T. This is to stated on the design drawing. Pins are to be identified at 100% tolerance.

11. Spring loaded coned pins shall be used for two-way and four-way datum holes and slots. Pin locators are to be recessed such that pins do not interfere with part orientation/location. In the event that OEM gauging standards require two-way and for-way locators to be designed at “MMC”, the two-way and four-way locators shall be designed using bushings and stab pins. The stab pins shall be doubled ended. One end of the stab pin
shall be constructed at MMC, the opposite shall be construction at RSF.
配有弹簧的锥形销被使用为双向和四向方式的基准孔和槽孔。定位销要被隐藏起来, 这样,定位销就不干扰到零件的定位取向/位置。如果OEM 测量的标准要求双向和为四向方式定位器设计在"MMC"（最大实体）的基础上, 双向和四向方式的定位器要使用衬套和刺针(Stab pin)。刺针(Stab pin) 要两头的. 一头要建设在MMC 上, 另一头要相反地设立在RSF (独立原则)上
12. All feeler checks are to be nominally 3.0mm. Go/No-Go feeler pins are to be provided for each tolerance range applicable. They will be marked with size, identified, and referenced to the sequence of operation. When more than one feeler is applied to a fixture, feelers will be identified with a color. The color will be recessed into the side of the holder to prevent removal of the I.D. color. The corresponding color must be also identified on the block and recessed. Feeler check clearance for shape should be 3.0 mm in between part and fixture with clearance and tolerances stamped on base and hand gauge. Specific colors will coordinate from tolerances.
所有测隙片在象征性是3.0mm 。Go/No 测隙针要适用于各个公差范围。它们的尺寸要被标记, 可被辨认, 和在操作时将参考数据序列出来。当在一套装置上用多于一种测隙片时, 不同的测隙片要着不同颜色来辨别. 颜色将被凹进支架的边以防止被识别的颜色撤掉, 而对应的颜色必须在座/台凹进处被辨别出来。测隙片用来检查形状的间隙, 而介于零件和装置间的间隙应该是3.0 毫米, 间隙和公差数据应被刻印在装置的底座和手测量仪上。指定的颜色要和公差相应对。以下是一般指定序列的颜色:
