Definitions
- the present invention relates to a machine tool, in particular for Machining of workpieces.
- Such a machine tool is for example by DE 199 07 617 A1 known.
- the known from DE 199 07 617 A1 machine tool has an im Machine frame pivotally mounted about a horizontal axis Double swivel table, whose one swivel table as a processing page and its another swivel table is provided as component side.
- the editing and Placement pages are separated by a splash guard and can be reversed by pivoting the double swivel table. Since the Double swivel table also equipped during the processing phase is the person who performs this assembly, the processing noise in full volume of up to about 90 dB exposed.
- the volume of the Machine tool to reduce outgoing machining noise.
- the goal is to eliminate all processing noise in the At least partially eliminate environment of the machine tool.
- a machine tool with at least one microphone for detecting processing noises of Machine tool, a phase shifter, which detected the amplitudes of Processing noises phase shifted by about 180 °, and at least one Speaker for outputting the phase-shifted processing noise.
- the processing noise of the machine tool corresponding noises whose amplitudes are phase-shifted by 180 °, superimposed, whereby the processing noise by interference with the phase-shifted processing sounds largely, ideally completely, be eliminated.
- This active noise reduction is both horizontal and used in vertical machine tools.
- each speaker is at such a distance from the place of origin Processing noise arranged that the processing noise and the phase-shifted machining noise in the environment of the machine tool at least partially eliminated.
- each is Speakers at such a distance to the place of origin Processing noise arranged that the processing noise and the phase-shifted machining noise at least at one Operating workstation of the machine tool, in particular on Placement workstation, at least partially eliminated.
- these are at least a microphone and the at least one speaker in the immediate vicinity of the Place of origin of the processing noise arranged.
- the machine tool is preferably in a processing side and a Component side, with at least one microphone and at least one Loudspeakers are arranged on the processing side.
- that can at least one microphone on or in the headstock of a work spindle of Machine tool to be arranged.
- the Machine tool mounted on an axis double swivel table, one swivel table as the processing side and the other swivel table as assembly side by pivoting the double swing table interchangeable are.
- a double pivoting table (double pivoting bar) 4 is pivotally mounted about a horizontal axis 3, one of its pivoting tables 4a (in FIG Machining page 5 and the other pivot table 4 b is provided on the component side 6 .
- the two pivoting tables 4a, 4b are mounted pivotably about a horizontal pivot axis 9 between and on two pivoting disks 8 , which are mounted laterally on the machine frame 2 about the horizontal axis 3.
- the swivel table 4b is equipped with open front door 10 with new workpieces, which are then edited by swapping the swivel tables 4a, 4b on the tool side 5 by means of recorded in the vertical work spindle 11 tool.
- both swiveling tables 4a, 4b are swiveled around their swivel axes 9 in the swiveling direction 12 as well as the swiveling swiveling table 4 in the swiveling direction 7 by 180.degree., Whereby the swivel tables 4a, 4b are replaced by those shown in FIG Arrangement results.
- a fixed splash guard wall 13 (eg, a thin sheet) is fixed, which in the illustrated in Fig. 1 Schwenkendposition of the double swivel table 4, the machining and assembly sides 5, 6 from each other.
- This splash guard wall 13 extends in a radial plane of the horizontal axis 3 between the two pivoting tables 4a, 4b and has on both sides of the horizontal axis 3 in the radially outer region in each case a wall opening 14 which is closable with a sliding door 15 .
- the two sliding doors 15 are each to be operated alternately in one of the two pivot end positions of the double swivel table 4.
- the swivel tables 4a, 4b are mounted on the swash plates 8 via their side walls 16 and on the vertical side walls 17 of the machine frame 2. On the two side walls 17 also loads the two-spindle work spindle 11 supporting cross member 18th
- a microphone 20 On the machining side 5, more precisely, on the headstock of the work spindle 11, a microphone 20 is arranged, which detects the machining noise of the machine tool 1 on the machining side 5. The detected processing noises are supplied to a phase shifter 21 , which phase-shifts the amplitudes of the detected processing noises by 180 °.
- two speakers 22 are further arranged, which deliver the phase shifter 21 supplied phase-shifted processing noise.
- the loudspeakers 22 are arranged at such a distance from the place of origin of the processing noises, ie to the machined workpiece or to the work spindle 11, that the processing noises and the phase-shifted processing noises cancel each other out as completely as possible due to interference in the environment of the machine tool 1.
- the microphone 20 is arranged centrally between the two speakers 22. As indicated by dashed lines in Fig. 1, the microphone 20 may be arranged on the processing side 5 alternatively or additionally also far from the place of origin of the processing noise.
- a machine tool 1 ' with horizontal work spindle 11' is shown at the headstock - as in the vertical machine tool 1 - a microphone 20 and two speakers 22 are arranged, which deliver the phase shifter 21 supplied phase-shifted processing noise.
