A tubular outer body has an open end and an inner body is threadedly received in the outer body for movement in opposite directions towards and away from the open end. A plurality of jaws are provided in the outer body adjacent the open end and movable between a tool-engaging and a tool-releasing position in response to movement of the inner body in the respective opposite directions. Elastic sealing means in the outer body intermediate the inner body and the jaws protects the inner body against entry of contaminants.

A dust-proof device for machine tool worktable comprises a worktable, a worktable base, a stainless steel dust cover, organ-type dust covers and L-shaped dust-proof plates. The worktable base is installed on a machine tool bridge. The upper portion of the worktable base is provided with a U-shaped through groove. Two ends of the stainless steel dust cover are sealed by the L-shaped dust-proof plates. The upper portion of each L-shaped dust-proof plate is fixed on the lower side of the stainless steel dust cover, and the lower portion of the L-shaped dust-proof plate is fixed on the machine tool bridge. Each organ-type dust cover is disposed under the stainless steel dust cover and has one end connected to the worktable base and the other end connected to the L-shaped dust-proof plate. The worktable covers the stainless steel dust cover and is connected to the worktable base by means of bolts.

A cutting apparatus includes a holding table for holding a workpiece, a feeding unit for moving the holding table in a feeding direction, first and second bellows connected to opposite ends of the holding table in the feeding direction, each of the bellows having an upper wall and opposite side walls adapted to be expanded and contracted for covering the feeding unit, a pair of drain channels provided along the sides of both bellows for receiving cutting water used in cutting the workpiece, and a scrap receptacle provided at the downstream end of the first bellows in the feeding direction for receiving scraps generated from the workpiece in cutting the workpiece. The cutting apparatus further includes a pair of fall prevention plates provided along the pair of drain channels for preventing scraps scattered onto the upper wall of the first bellows from falling into the drain channels.

Machine tool having a bed, a table arranged on the bed, a first saddle provided free to travel back and forth, a second saddle supported on the first saddle and provided free to travel side to side, a spindle head provided free to travel perpendicularly on the second saddle, a main spindle situated above the table and by the spindle head supported free to rotate on its center axis, a front cover provided on the front side of the bed and furnished with doors that open and close sideways, and top covers configured with one end sideways shiftably connected to the front side of the first saddle, and with another end connected extensibly/retractably to the top of the front-cover doors, therein being configured for permitting back-and-forth-directed movement of the first saddle.
摘要:
A multi-sided bellows cover has panel sections formed of extruded plastic panels in which rigid wall sections are connected at the fold lines by flexible web sections. The web sections are integrally molded by extrusion with at least one adjacent wall section, and many serial wall sections alternating with web sections may be integrally co-extruded with one another. Intermittently, a bead of one of the flexible web sections of one of the panel sections is captured in a slot of one of the rigid wall sections of another panel section.
摘要:
A multi-sided bellows cover has panel sections formed of extruded plastic panels that are connected end-to-end by bead-in-slot connections. The panel sections can be made of one or more rigid wall sections that are connected at the fold lines by flexible web sections or by the bead-in-slot connection. The panel sections are integrally molded by extrusion, and many serial wall sections alternating with web sections may be integrally co-extruded with one another.

A connecting device rotatably joins a protective plate to a bellows that covers the guide of an automatic machine, machine tool or robot. The plate is one of a plurality of partially overlapping protective plates that slide and turn relative to each other as the bellows is extended and compressed. The connecting device comprises: a pushing element designed to extend freely through an aperture made in the respective plate and to come into contact with an outside face of the plate itself; a joining element which can be stably connected to the bellows at a respective transversal fold line and which is designed to come into contact with an inside face of the respective plate so as to rotatably support the plate in removable, pivot-like fashion when the plate is pushed by the pushing element; and a pair of helical springs forming a single component with the pushing element and stably connected to the joining element.
