The modular fixture is developed on the base of standardization, specification, catenation of the component of the fixture. Using the fixture, it can save time and material on designing, shorten the produce periods, assured the product quality.

组合夹具是在夹具零部件高度标准化、规格化、系列化的基础上发展起来的，使用组合夹具可节约夹具设计制造工时和材料、缩短生产准备周期、保证产品质量。

The tongs all passes in the machine the gearing on the bed what tongs the gearing on realizes with superficial contact in the cowgirl on the bed in machine or matches.when the tongs installs in the machine bed work on the stage,the center of gravity of the tongs should be as far as possible low,center of gravity the more high an accepts should the dint is more big,the tongs bottom four directions should bulge,make its contact good,or the bottom establishes four a feets.when the tongs installs on the machine bed principal axis,the tongs install the to should have the enough match accuracy with principal axis cowgirl surface,and guarantee the gearing the stability dependable.

夹具体在机床上的安装都是通过夹具体上的安装基面与机床上的相应表面的接触或配合实现的。当物流设备需要的公司体在机床工作台上安装时，夹具的服装厂应尽量低，重心越高则支承面应力越大，夹具底面四边应凸出，使其接触良好，或底部设置四个支脚。当夹具体在机床主轴上安装时，夹具安装基面与主轴相应表面应有足够的配合精度，并保证安装稳定可靠。

Is living start examines that among this Bu Gongxu to examine the substance that the clamping apparatus will be examineed is consising of of many-sides :Contactor distance turningon、Super range、Synchronousness ,Besides produce exterior examination 、Movement property、Jie's electric strength also is living , and this one-step workman completees in the sequence
