Abstract:
The invention concerns a covering for the bed of a machine tool, the covering comprising telescoping boxes, each of which has a first and a second wall and a roof joined to the walls. Mounted on at least one wall is an outwards-projecting entrainment lug designed to engage with an appropriately shaped device on the next-larger box. The entrainment lug is formed on a profile mounted on one of the walls. Fitted to the entrainment lug is a damping element which damps the impact between the entrainment lug and the device with which it engages. Also fitted to the profile is a stop which can be brought in contact with the profile or rear wall of the next-larger box. The stop acts to damp the impact between two boxes.
Abstract:
The proposed covering comprises telescoping boxes, each of which has a first and a second wall and a roof (7) joined to the walls. Fitted to the roof between the walls is a girder (8) with at least one channel (17, 9, 13) which is open at the top.
Abstract:
The aim of the invention is an energy supply line guiding chain made up of articulated interconnected chain links. The energy feed chain has a channel (6) extending in the longitudinal direction of the feed chain (6) to accommodate energy supply lines. The channel (6) is defined by the chain links (2, 3, 4 and 5). Each chain link has an opening (7, 8, 9, 10) leading into the channel (6). The opening (7, 8, 9 and 10) is defined by at least one bar (11, 12a, 12b; 13a, 14a, 14b). Each bar (11, 12a, 12b; 13a, 13b; 14a, 14b) is rigid. The openings (7, 8, 9 and 10) of the neighbouring chain links (2, 3, 4, 5) are disaligned, perpendicular to the longitudinal axis of the chain (1). Preferably, the energy supply line chain (1) includes a self-repeating link sequence (16) comprising at leas two neighbouring chain links (2, 3, 4, 5) with disaligned openings (7, 8, 9, 10).
Abstract:
The invention relates to a chain link (2) for a power transmission chain (1) serving to accommodate cables, hoses and the like, with elongated side walls (3) and transverse bridges (4) connecting said side walls. Each side wall has sliding surfaces (7) to allow mobile connection to a side part of a neighbouring chain link. The respective sliding surfaces (7) of adjacent chain links (2) are made from different materials; at least some of the sliding surfaces (7) are made in such a way that an additional element (5; 6) is joined to at least one side wall (3) before the chain (1) is assembled, the additional element being made from a different material from that of the side wall. Fitting the additional element to a chain link before, rather than during, assembly of the chain simplifies assembly of the chain links and facilitates automated assembly procedures.
Abstract:
The invention relates to a fastening arrangement with a chain link (1). The chain link (1) has two remote link plates lying opposite each other (2, 3) with edge faces and side faces (4, 5, 6) and at least one crossbar (7) connecting the link plates (2, 3). Included in the invention is a fixing unit (8) with spaced rods (9, 10) extending in the longitudinal direction of the link plates (2, 3). The fixing unit (8), the crossbar (7) and/or at least one link plate (2, 3) have interacting joints and fastenings (13, 20), whereby the fixing unit (8) can be joined to the crossbar (7) and/or at least one link plate (2, 3) with rods (9, 10) which are directed into or into and out of the chain link (1).
Abstract:
A process is disclosed for creating a non-detachable connection between two plastic parts (1, 2), the connection allowing a degree of movement between the plastic parts (1, 2). The connection is made by forming at least one tab (3, 4) on one of the plastic parts. The tab (3, 4) is then deformed until it encloses a region of the second plastic part in such a way as to be non-detachable. Finally, the shape of the tab (3, 4) thus obtained is set. A connection of this type can be used advantageously to connect the sections of a power conducting chain.
Abstract:
The invention concerns a chain link for an energy-conveying chain. The chain link comprises two opposite link plates (2) which are at a mutual spacing, and at least one cross beam (5). The cross beam (5) comprises at both ends a detachable hinge (10) which can be connected to the link plate (2). The cross beam (5) can be locked to the link plate (2). In order to lock the cross beam (5) to the link plate (2), the hinge (10) comprises a hinge pin (7) and a recess (15) which co-operates with the latter and has undercuts (14). The hinge pin (7) comprises a locking projection (9) which engages in a cut-out (16) extending over part of the periphery of the recess (15).
Abstract:
A tie-bar (16) is proposed for connection at its face with the lateral sections (2a', 2b') of a chain link. The tie-bar (16) is provided with a securing groove (10) which is open to the middle of the chain link, the groove being bounded by two parallel ridges connected by a base plate (11). The securing groove (10) can accommodate elements such as strain relief units (5) for power lines. At least one connection hole can be provided in the base plate and the tie-bar with the chain link creates a possible connection for a power conducting chain at a fixed or moveable point.
Abstract:
A connection piece (1) for a power conducting chain is disclosed. A chain link (2) for such a power conducting chain is basically U-shaped with two lateral sections (4a, 4b) and a connecting stay (3) which connects the lateral sections. The lateral sections each have articulating sections by which the chain link is connected to the next link. The connecting stay of the connection piece (1) takes the form of a connecting plate (6). The articulating sections are those of a normal chain link. At least two holes (7a, 7b) can be drilled in the connecting plate (6) in a line along the longitudinal axis of the chain. The connection piece (1) can be used at either end of the power conducting chain in either one of two configurations.
