    • In its preferred embodiment this jig is a rigid foam plastic casting specific to a particular type of workpiece. It enables accurate fastening of workpiece to external structure with flathead screws. Each such workpiece has a plurality of countersunk orifices of identical size and distribution pattern. Jig and workpiece are of general rectangular plan, the jig thick enough to allow for integral functional guide holes. Jig is fitted to workpiece and the associated two held against an external structure while pilot holes are drilled into the structure through the jig guide holes centered with respect to the workpiece orifices. Proper orientation of jig to workpiece is obtained and maintained by a plurality of truncated conical protuberances on the jig extending from one of its two major parallel surfaces. These protuberances are complementary in shape and distribution pattern to the countersunk orifices of the workpiece. When protuberances are severally and simultaneously fitted into orifices, that surface of the jig from which the protuberances extend will be juxtaposed and common to that surface of the workpiece exhibiting contersunk recesses. This insures proper orientation and inherent stability during drilling of pilot holes. Where the jig substance permits, grooves are provided to allow breaking cleanly into several parts, if desired, each part constituting one jig with one protuberance.
    • 在其优选实施例中,该夹具是特定于特定类型的工件的刚性泡沫塑料铸件。 它可以使用平头螺钉将工件精确地紧固到外部结构。 每个这样的工件具有多个相同尺寸和分布图案的沉头孔。 夹具和工件具有一般矩形平面图,夹具厚度足以允许整体功能导向孔。 夹具安装在工件上,相关的两个固定在一个外部结构上,而导向孔通过相对于工件孔中心的夹具导向孔钻进结构中。 通过夹具从其两个主平行表面之一延伸的夹具上的多个截锥形突起获得并维持夹具对工件的正确取向。 这些突起在形状和分布方式上与工件的沉孔相互补充。 当突起分别同时装配到孔中时,突起延伸的夹具的表面将并列并且表现为表现出锥形凹槽的工件的表面。 这样可确保钻孔过程中导向孔的正确定位和固有的稳定性。 在夹具物质允许的情况下,设置槽以允许破碎成几个部分,如果需要,每个部件构成一个具有一个突起的夹具。
