Date of release:2017-08-31 Author: Click:

　　As special vehicles and special engineering vehicles to small batch production, diversification direction, in the development of new models and manufacture process, use of flexible, modular three-dimensional combination equipment replace traditional special tooling, can not only shorten the time required for the design, manufacture, and can be repeatedly used, cost savings, it is very economic and practical choice.

　　1, economy

　　Three dimensional flexible combination fixture is a kind of universal fixture can free combination, can adapt to different workpiece shape, several sets of fixture system can replace a large number of the high cost of special tooling, after using the tooling, can save due to product changes into the specialized equipment and tooling cost and time. In many varieties, personalized car production, its economical efficiency is especially obvious.

　　Foreign data have shown that the cost of more than 9 sets of special welding jig (5 ~ 6 sets) in our country has more than a set of flexible fixture. At present, China's automobile manufacturing enterprises increase each year dozens of sets of special welding jig is very common, selects the flexible fixture economy is obvious.

　　2, flexible

　　Three dimensional flexible tooling platform can be combined in three-dimensional space. Modular system in the installation, adjustment and clamping workpiece perfectly reflected its general function, on the welding of large workpieces, the more prominent characteristics. The other side of the flexibility in easy operation. On the bench and module, all with 12.5 mm and 25 mm as multiple dimensions can be found directly, coupled with a small amount of adjustment, can be convenient accurate positioning.

　　3, accuracy

　　所有模块加工精度均较高，工作平台上任意两个孔的公差在±0.1mm以内，完全可以满足焊接加工的需要。在装配或焊接过程中，使用定位块、连接块、夹紧器和支撑块，能够对工件精确定位，需要焊接的工件可以被稳定地固定在各个定位点或定位面上。如果工件本身的几何尺寸不准确，也可以很快被检测出来，在初加工工序中便被消除。

　　4、重复性

　　使用CAD及Pro/E设计系统，可以非常简便地对样件进行模拟装配，精确的模块尺寸能保证装配精度。

　　5、耐用性

　　在工作平台和模块结构设计中，充分考虑了使用刚性和强度的要求，每个标准2000mm×1000mm的工作平台载重量可达10t，并能保证其重复定位和夹紧的精度。工作平台和模块的表面经过特殊处理，使焊接时产生的飞溅不容易粘在其工作表面。定位和夹紧销栓表面经过淬火处理，使其不易磨损、经久耐用。

　　当中国从“中国制造”走向“中国创造”后，会有更多的中国自主的柔性组合夹具品牌为世界所认知。柔性组合工装夹具产业作为支撑汽车发展的劲旅，生机盎然，怀揣民族工业精神的这支产业必将走向世界，迈向辉煌！
