PCT No. PCT/DE93/00261 Sec. 371 Date Sep. 27, 1994 Sec. 102(e) Date Sep. 27, 1994 PCT Filed Mar. 23, 1993 PCT Pub. No. WO93/19893 PCT Pub. Date Oct. 14, 1993.The invention concerns a chain magazine designed to hold the machining tools for machining devices, in particular tooling machines. The magazine comprises a continuous chain fitted with holder devices for the machining tools and driven by at least two sprockets and guided by guide elements up to the point of contact with the pitch diameter of the drive or guide sprocket wheel. The chain magazine further comprises chain links consisting of a connecting bar and, joined to the bar, two tubular sleeve elements of different diameter which form the flexible couplings between the links. Holder devices for machining tools are disposed coaxially to the hinge axes in the mutually encircling tubular sleeves under a small motion clearance. Shaft-like cutouts are furnished in each of the tubular sleeves and exhibiting parallel faces disposed spaced apart and directed toward the center axes of the holder devices. Said cutouts form an open insertion channel or, respectively, removal channel in the respective insertion position or, respectively, removal position of the chain hinge. The respective (outer) tubular sleeve, which surrounds the (inner) tubular sleeve of a smaller diameter, exhibits in a sector of its circumference a recess of the thickness of the connecting bar. |
