ABSTRACT:
A modular tooling system having two or more base plates joined by elongated extender members and having a tubular member with opposite ends which are closed by cover members, each of which has an inner portion dimensioned to fit within the interior of the tubular member. The cover members are formed with through-holes with one of the cover members formed with threaded through-holes while the through-holes of the other cover member are non-threaded. An access opening, positioned in the side of the tubular member and proximate to the non-threaded through holes, permits the removal and insertion of fasteners into the non-threaded through holes for engagement with the threaded through-holes of the cover member attached to another tubular member or to threaded through-holes formed in one of the base plates. Alternatively, a double threaded, dowel fastener may be used to join the cover members each having threaded through-holes, of two tubular members. The dowel fastener includes a first threaded portion and a smaller threaded portion separated by a dowel section. The first threaded portion threadably engages the threaded through-holes of one of the cover members while the smaller threaded portion is dimensioned to pass through the through-holes of the abutting cover member and receive a rotating fastener. Each tubular member is preferably a quadrilateral with opposing sidewall pairs, each pair having matching through-holes defined in said sidewall pairs. The matching through-holes receive an insert formed with an enlarged head and elongated body with an matching axial opening running therethrough. The axial opening of the insert may be threaded to enable attachment of components to the sides of the tubular member. Alternatively, the axial opening of the insert is non-threaded, permitting attachment of a workpiece to one side of the tubular member.
