Description
[technical field]
The present invention relates to a kind of spindle nose of machining center machine, particularly relate to a kind of can be along the spindle nose of the machining center machine of Z-direction lifting.
[background technology]
Consult Fig. 1, Fig. 2 and Fig. 3, the spindle nose 1 of general machining center machine consists predominantly of a headstock 11, an axle bed 12, two pairs of line rails 13, a plurality of slide block 14, a driver element 15 and machining cells 16.
This headstock 11 has and is formed on the rail groove 112 that extend along a Z-direction in a front.This axle bed 12 is to pass this rail groove 112, and has the relative two side faces 121 and a back side 122 towards these rail groove 112 cell walls.Aforementioned line rail 13 is to be installed on these axle bed 12 two side faces 121.Aforementioned slide block 14 be installed in respectively these rail groove 112 2 relative cell walls and with aforementioned line rail 13 sliding closing.This driver element 15 has a plurality of swivel nuts 151 and a screw rod 152.Aforementioned swivel nut 151 is to be installed in this rail groove 112 another cell walls, but this screw rod 142 be turn be positioned at the back side 122 of this axle bed 12, driven by a power source (figure does not show) and rotate.This machining cell 16 is arranged in the axle bed 12, and has clamping one cutter 161 and be arranged on a spindle nose 162 of these axle bed 12 1 lower ends.
When this screw rod 152 during along aforementioned swivel nut 151 turns, can drive this axle bed 12 with aforementioned line rail 13 along aforementioned slide block 14 upper and lower lifting displacements, whereby, make this spindle nose 162 relative workpiece 8 displacements, and the action of processing with 161 pairs of these workpiece 8 of cutter.
Yet, since aforementioned line rail 13 and this screw rod 152 fixing with the location after, be outstanding respectively these axle bed 12 two side faces 121 and the back side 122, therefore, if the shape of this workpiece 8 or highly different, though this cutter 161 can be processed the machined surface of this workpiece 8 smoothly, but, this workpiece 8 is along the outstanding position of Z-direction, but be easy to the situation of the aforementioned line rail 13 of bump or this screw rod 152, cause aforementioned line rail 13 or this screw rod 152 to damage, not only can influence the processing precise degree of this workpiece 8, and can form a processing restricted area, make workpiece 8 in this restricted area, all can't finish processing.
Consult Fig. 4, Fig. 5, Fig. 6, when this axle bed 12 during respectively along an X-axis or along a Y direction displacement and processing work, this axle bed 12 can bear directed force F X, the FY from X-direction or Y direction respectively, and make aforementioned slide block 14 bear the torsional moment of a MA direction respectively, and this line rail 13 floats with the direction around X-axis relatively, or bear the torsional moment of a MB direction, and relatively this line rail 13 with direction turn around Y-axis, or bear the torsional moment of a MC direction, and relatively this line rail 13 with direction turn around the Z axle.
Consult Fig. 5, because aforementioned line rail 13 is to be separately positioned on this axle bed 12 two sides 121 with aforementioned slide block 14, therefore, when this axle bed 12 when directed force F X is born in this X-direction displacement, aforementioned line rail 13 can be because the direction of directed force F X, make aforementioned slide block 14 can only bear the moment of MB, MC direction respectively, and can't bear the moment of MA direction.Consult Fig. 6, when this axle bed 12 when directed force F Y is born in this Y direction displacement, aforementioned line rail 13 can be because the direction of directed force F Y makes aforementioned slide block 14 can only bear the moment of MA, MC direction respectively, and can't bear the moment of MB direction.So these axle bed 12 work in-processes are easy to generate vibration, and cutting rigidity deficiency, make the machined surface of this workpiece smooth inadequately, have a strong impact on the processing precise degree of this workpiece.

[specific embodiment]
Consult Fig. 7, Fig. 8, reach Fig. 9, the preferred embodiment of the spindle nose of machining center machine of the present invention comprises: a headstock 2, an axle bed 3, a line rail group 4, a slide block group 5, a driver element 6 and a machining cell 7.
This headstock 2 has a rail groove 22 that is formed on a front and extends along a Z-direction.
This axle bed 3 is to pass this rail groove 22 along this Z-direction, and have one first conduit 32 and one second conduit 33 that is formed on relative two side faces 31 and extends, and the recess 35 and 2 the 3rd conduits 36 that are formed on another side 34 and extend along this Z-direction along this Z-direction.
This line rail group 4 has one first line rail 41, one second line rail 42 and two three-way rails 43.This first, second line rail 41,42 and aforementioned three-way rail 43 are to be embedded in these axle bed 3 first, second conduits 32,33 and in aforementioned the 3rd conduit 36 along this Z-direction respectively, and outstanding these axle bed 3 sides 31,34.
This slide block group 5 has a plurality of first slide blocks 51, a plurality of second slide block 52 and a plurality of the 3rd slide block 53, aforementioned first, second, third slide block the 51,52, the 53rd is separately fixed at this rail groove 22 relative two cell walls and another cell wall, and place in this first, second, third conduit 32,33,36 and with these first, second, third line rail, 41,42,43 sliding closing.
This driver element 6 has a plurality of swivel nuts 61 and a screw rod 62.Aforementioned swivel nut 61 is to be installed in this rail groove 22 another cell walls.But this screw rod 62 is turn ground to pass this recess 35 and screws togather with this swivel nut 61 along this Z-direction, and the another side 34 of outstanding this axle bed 3 not.
This machining cell 7 is arranged in the axle bed 3, and has clamping one cutter 71 and be arranged on a spindle nose 72 of these axle bed 3 one lower ends.
Whereby, when a power source (figure do not show) drives this screw rod 62 along aforementioned swivel nut 61 turns, can driven in synchronism this axle bed 3 with aforementioned first, second, third line rail 41,42,43 along 51,52, the 53 upper and lower lifting displacements of aforementioned first, second, third slide block, make this spindle nose 72 relative workpiece 8 displacements, reach the action of processing with 71 pairs of these workpiece 8 of this cutter.
What deserves to be mentioned is, because this first, second, third line rail 41,42,43 and this screw rod 62 all are to be embedded in first, second, third conduit 32,33,36 and this recess 35 of this axle bed 3, therefore, can't give prominence to this axle bed 3 sides 31,34, certainly just do not interfere the doubt of this workpiece 8 yet, can reduce the machining interference zone, and protect this first, second, third line rail 41,42,43.
Consult Figure 10, when this axle bed 3 during along an X-direction displacement and processing work, this axle bed 3 can bear the directed force F X from X-direction, at this moment, because this axle bed 3 is limited in three orientations by aforementioned first, second, third slide block 51,52,53 with aforementioned first, second, third line rail 41,42,43, therefore, the moment of MB, MC direction can be born with aforementioned first slide block 51 by the aforementioned first line rail 41 respectively, and the moment of MA, MC direction then can be born by aforementioned second, third line rail 42,43 and aforementioned second, third slide block 52,53 respectively.Whereby, rigidity and processing precise degree are cut in vibration frequency, the raising that can fall to this axle bed 3.
Consult Figure 11, when this axle bed 3 during along a Y direction displacement and processing work, this axle bed 3 can bear the directed force F Y from Y direction, at this moment, because this axle bed 3 is limited in three orientations by aforementioned first, second, third slide block 51,52,53 with aforementioned first, second, third line rail 41,42,43, therefore, the moment of MA, MC direction can be born with aforementioned first slide block 51 by the aforementioned first line rail 41 respectively, and the moment of MB, MC direction then can be born by aforementioned second, third line rail 42,43 and aforementioned second, third slide block 52,53 respectively.Whereby, rigidity and processing precise degree are cut in vibration frequency, the raising that can fall to this axle bed 3.
