Abstract
An arrangement for withdrawing particles of material removed by a working tool of a machine tool during a machining process, comprises a working frame adapted to support a machine tool, casing forming an at least partially closed chamber adapted to surround the working tool so as to accommodate the particles of material removed during machining process, port elements communicating with the chamber and adapted to be connected to a suction source so as to aspirate the particles from the chamber, and mounting elements for mounting the casing on the working frame so that the chamber surrounds the working tool when the machine tool is supported by the working frame.
Claims19
An arrangement for withdrawing of material removed by a working tool of a machine tool during a machining process, comprising a working frame adapted to support a machine tool;
- casing means forming an at least partially closed chamber adapted to surround the working tool so as to accommodate the particles of material removed during the machining process, said casing means including two sleeves movable one within another has been inserted;
- port means communicating with said chamber and adapted to be connected to a suction source so as to aspirate the particles from said chamber;
- connecting means for connecting said port means to the suction source, said connecting means being mounted on said working frame, said working frame having a hollow portion forming a suction box which communicates with the suction source, on the one hand, and with said chamber of said casing means on the other hand, so as to form said connecting means;
- and means for mounting said casing means on said working frame so that said chamber surrounds said working tool when said machine tool is supported by said working frame, said mounting means immovably connecting one of said sleeves to said working frame, whereas the other of said sleeves is movable relative to said one sleeve between a plurality of locations and fixable to said one sleeve in each of said plurality of locations.
An arrangement for withdrawing of material removed by a working tool of a machine tool during a machining process, comprising a working frame adapted to support a machine tool;
- casing means forming an at least partially closed chamber adapted to surround the working tool so as to accommodate the particles of material removed during machining process, said casing means including two sleeves movable one within another, one of said sleeves being immovably connected to said frame, whereas the other of said sleeves is movable relative to said one sleeve between a plurality of locations and fixable to said one sleeve in each of said plurality of locations, said sleeves including an inner sleeve, and an outer sleeve surrounding said inner sleeve and having through-going apertures;
- fixing means for fixing said outer sleeve to said inner sleeve in each of said plurality of locations, and including a spring member surrounding said outer sleeve and partially extending inwardly beyond said outer sleeve so as to frictionally engage said inner sleeve, whereby said outer sleeve is fixed to said inner sleeve;
- port means connected with said other sleeve so as to communicate with said chamber and adapted to be connected to a suction source so as to aspirate the particles from said chamber;
- and means for mounting said casing means on said working frame by immovably connecting said one sleeve to said working frame so that said chamber surrounds said working tool when said machine tool is supported by said working frame.
An arrangement for withdrawing of material removed by a working tool of a machine tool during a machining process, comprising a working frame adapted to support a machine tool, said working frame having a portion which receives the working tool therein which portion is a separate collar connected to said working frame;
- casing means forming an at least partially closed chamber adapted to surround the working tool so as to accommodate the particles of material removed during machining process, said casing means including two sleeves movable one within another, one of said sleeves having an upper section facing forward said collar;
- port means communicating with said chamber and adapted to be connected to a suction source so as to aspirate the particles from said chamber;
- and means for mounting said casing means on said working frame so that said chamber surrounds said working tool when said machine tool is supported by said working frame, said mounting means immovably connecting said one sleeve to said working frame, whereas the other of said sleeves is movable relative to said one sleeve between a plurality of locations and fixable to said one sleeve in each of said plurality of locations, said mounting means fixing said upper section of said one sleeve to said collar of said working frame and including an endless helical spring surrounding said one sleeve and biasing the latter into fixing engagement with said collar of said working frame.
