The designing features of automobile body

welding fixture

Auto body clamp is required for the amorphous body stamping required to locate and clamp, to form the body components, combined parts, sub-assembly and assembly, While taking advantage of suitable welding method to form their own welding pieces of the whole. Welding fixture welding process is a secondary device, but in the process of mass production car body, the device is essential. It not only can improve welding productivity, but also to ensure the dimensional accuracy of welding products and appearance requirements of the important devices. The assembly and welding fixtures there is no uniform specifications and standardization, are non-standard equipment. Design.and manufacturing process according to the structural characteristcs of the specific models, production conditions and the actual demand from the line of design and manufacturing.

Application and development

Of case based reasoning in fixture design

Fixtures are devices that serve as the purpose of holding the workpiece securely and accurately, and maintaining a consistent relationship with respect to the tools while machining. Because the fixture structure depends on the feature of the product and the status of the process planning in the enterprise, its design is the bottleneck during manufacturing, which restrains to improve the efficiency and leadtime. And fixture design is a complicated process, based on experience that needs comprehensive qualitative knowledge about a number of design issues including workpiece configuration, manufacturing processes involved, and machining environment. This is also a very time consuming work when using traditional CAD tools (such as Unigraphics, CATIA or Pro/E), which are good at performing detailed design tasks, but provide few benefits for taking advantage of the previous design experience and resources, which are precisely the key factors in improving the efficiency. The methodology of case based reasoning (CBR) adapts the solution of a previously solved case to build a solution for a new problem with the following four steps: retrieve, reuse, revise, and retain [1]. This is a more useful method than the use of an expert system to simulate human thought because proposing a similar case and applying a few modifications seems to be self explanatory and more intuitive to humans .So various case based design support tools have been developed for numerous areas[2-4], such as in injection molding and design, architectural design, die casting die design, process planning, and also in fixture design. Sun used six digitals to compose the index code that included workpiece shape, machine portion, bushing, the 1st locating device, the 2nd locating device and clamping device[5]. But the system cannot be used for other fixture types except for drill fixtures, and cannot solve the problem of storage of the same index code that needs to be retained, which is very important in CBR[6].

Mechanical Design

Abstract:A machine is a combination of mechanisms and other components which transforms, transmits. Examples are engines, turbines, vehicles, hoists, printing presses, washing machines, and movie cameras. Many of the principles and methods of design that apply to machines also apply to manufactured articles that are not true machines. The term "mechanical design" is used in a broader sense than "machine design" to include their design. the motion and structural aspects and the provisions for retention and enclosure are considerations in mechanical design. Applications occur in the field of mechanical engineering, and in other engineering fields as well, all of which require mechanical devices, such as switches, cams, valves, vessels, and mixers.

缸体机械加工工艺设计

发动机缸体是发动机零件中结构较为复杂的箱体零件，其精度要求高，加工工艺复杂，并且加工加工质量的好坏直接影响发动机整个机构的性能，因此，它成为各个发动机生产厂家所关注的重点零件之一。

1. 发动机缸体的工艺特点

缸体为一整体铸造结构，其上部有4个缸套安装孔；缸体的水平隔板将缸体分成上下两部分；缸体的前端面从到后排列有三个同轴线的凸轮轴安装孔和惰轮轴孔。

缸体的工艺特点是：结构、形状复杂；加工的平面和孔比较多；壁厚不均，刚度低；加工精度要求高，属于典型的箱体类加工零件。缸体的主要加工表面有顶面、主轴承侧面、缸孔、主轴承孔及凸轮轴孔等，它们的加工精度将直接影响发动机的装配精度和工作性能，主要依靠设备进度、工夹具的可靠性和加工工艺的合理性来保证。

Machining fixture locating and clamping position optimization using genetic algorithms

Fixtures are used to locate and constrain a workpiece during a machining operation, minimizing workpiece and fixture tooling deflections due to clamping and cutting forces are critical to ensuring accuracy of the machining operation. Traditionally, machining fixtures are designed and manufactured through trial-and-error, which prove to be both expensive and time-consuming to the manufacturing process. To ensure a workpiece is manufactured according to specified dimensions and tolerances, it must be appropriately located and clamped, making it imperative to develop tools that will eliminate costly and time-consuming trial-and-error designs. Proper workpiece location and fixture design are crucial to product quality in terms of precision, accuracy and finish of the machined part.

数控机床夹具的发展趋势

1.国内外研究历史和现状

1.2 国内机床夹具发展历史

我国国内的夹具始于20世纪60年代，当时建立了面向机械行业的天津组合夹具厂，和面向航空工业的保定向阳机械厂，以后又建立了数个生产组合夹具元件的工厂。在当时曾达到全国年产组合夹具元件800万件的水平。20世纪80年代以后，两厂又各自独立开发了适合NC机床、加工中心的孔系组合夹具系统，不仅满足了我国国内的需求，还出口到美国等国家。当前我国每年尚需进口不少NC机床、加工中心，而由国外配套孔系夹具，价格非常昂贵，现大都由国内配套，节约了大量外汇。

1.2国外机床夹具发展历史

从国际上看俄国、德国和美国是组合夹具的主要生产国。当前国际上的夹具企业均为中小企业，专用夹具、可调整夹具主要接受本地区和国内订货，而通用性强的组合夹具已逐步成熟为国际贸易中的一个品种。有关夹具和组合夹具的产值和贸易额尚缺乏统计资料，但欧美市场上一套用于加工中心的夹具，通常为机床价格的1110﹩到1115﹩，而组合夹具的大型基础件尤其昂贵。由于我国在组合夹具技术上有历史的积累和性能价格比的优势，随着我国加入WTO和制造业全球一体化的趋势，特别是电子商务的日益发展，其中蕴藏着很大的商机，具有进一步扩大出口良好前景。

1.3 国内外机床夹具发展现状

国际生产研究协会的统计表明，目前中、小批多品种生产的工件品种已占工件种类总数的85％左右。现代生产要求企业所制造的产品品种经常更新换代，以适应市场的需求与竞争。然而，一般企业都仍习惯于大量采用传统的专用夹具，一般在具有中等生产能力的工厂，里约拥有数千甚至近万套专用夹具；另一方面，

如何延长轴承寿命

摘要：自然界苛刻的工作条件会导致轴承的失效，但是如果遵循一些简单的规则，轴承正常运转的机会是能够被提高的。在轴承的使用过程当中，过分的忽视会导致轴承的过热现象，也可能使轴承不能够再被使用，甚至完全的破坏。但是一个被损坏的轴承，会留下它为什么被损坏的线索。通过一些细致的侦察工作，我们可以采取行动来避免轴承的再次失效。

关键词：轴承失效寿命

导致轴承失效的原因很多，但常见的是不正确的使用、污染、润滑剂使用不当、装卸或搬运时的损伤及安装误差等。诊断失效的原因并不困难，因为根据轴承上留下的痕迹可以确定轴承失效的原因。

然而，当事后的调查分析提供出宝贵的信息时，最好首先通过正确地选定轴承来完全避免失效的发生。为了做到这一点，再考察一下制造厂商的尺寸定位指南和所选轴承的使用特点是非常重要的。

1 轴承失效的原因

在球轴承的失效中约有40%是由灰尘、脏物、碎屑的污染以及腐蚀造成的。污染通常是由不正确的使用和不良的使用环境造成的，它还会引起扭矩和噪声的问题。由环境和污染所产生的轴承失效是可以预防的，而且通过简单的肉眼观察是可以确定产生这类失效的原因。

通过失效后的分析可以得知对已经失效的或将要失效的轴承应该在哪些方面进行查看。弄清诸如剥蚀和疲劳破坏一类失效的机理，有助于消除问题的根源。

只要使用和安装合理，轴承的剥蚀是容易避免的。剥蚀的特征是在轴承圈滚道上留有由冲击载荷或不正确的安装产生的压痕。剥蚀通常是在载荷超过材料屈服极限时发生的。如果安装不正确从而使某一载荷横穿轴承圈也会产生剥蚀。轴承圈上的压坑还会产生噪声、振动和附加扭矩。
