Abstract

Abstract In producing spherical and polyhedral connectors for space frameworks from blanks a tapped through hole is first formed through the center of the blank. The blank is then engaged by its through hole in a clamping device that is rotatable along the axis of the through hole, the clamping device being mounted on an element that is rotatable on an axis at right angles to the axis of the through hole and which intersects the axis of the through hole at right angles. Tool means positioned adjacent the clamp to work on the blank engaged thereby operate along an axis disposed perpendicular to the first two mentioned axes, the tool means being operative to machine the blank at fixed spatial positions to which the blank is adjusted by movement about the first two axes, the tool means boring holes in the blank, machining flats around said holes at right angles to the holes and tapping the holes. Between these machining operations the tool means are moved relative to the clamping device and the connector blank about a further axis common to the tool means and the clamping device. The connector blank is then positioned to a new predetermined spatial position by the clamping device and the tool means produce another hole while the blank is maintained in the original clamping device by its through hole whereby a plurality of accurate spaced holes are produced in the connector blank.

Claims Analysis

Total Claims: 2
Claim 1
Independent Claim 108 words
A process as set forth in claim 1, characterized by securing several connector blanks laterally at a spacing from one another in a clamping device along the axes (I) of their through holes, in such a manner that their axes (I) intersect the axis of rotation (II) of the clamping device; rotating the connector blanks together about their through hole axes (I) and about the axis of rotation (II) of the clamping device commonly associated with the connector blanks to alternatingly adjust the connector blanks to the various spatial positions; and simultaneously machining the connector blanks in the fixed spatial positions along the axes (III) of several tools.
Claim 2
Dependent Claim 49 words
A process as set forth in claim 1 in which said machining step (g) includes drilling and tapping individual holes in the connector blank of a length derived from the length of the through hole (axis I) in the connector blank produced by the truncating or countersinking step (b).
