The specific embodiment
Structural representation of the present utility model such as Fig. 1, a kind of Machine Tool Main Drive central water outlet structure, comprise gearbox 1, swivel joint 2, transition axis 1, splined shaft 1, spline housing 1, transition axis 26, splined shaft 27, spline housing 28, transition axis 39, pine cutter pull bar 10, main shaft 11, transition axis 4 12, loose knife oil cylinder piston 13, O type circle 1, O type circle 2 15, O type circle 3 16 and O type circle 4 17, be provided with swivel joint 2 at gearbox 1 inferoanterior, swivel joint 2 adopts left hand thread, swivel joint 2 rears are provided with transition axis 1, transition axis one 3 rears are provided with splined shaft 1, splined shaft one 4 rears are provided with splined shaft 27, splined shaft 1 is connected by spline housing 1 with splined shaft 27, splined shaft 1 and the splined shaft 27 junctions transition axis 26 of packing into, splined shaft 27 rears are provided with main shaft 11, splined shaft 27 is connected by spline housing 28 with main shaft 11, splined shaft 27 and the junction of main shaft 11 transition axis 39 of packing into, transition axis 39 rears are provided with loose cutter pull bar 10, transition axis 39 is provided with transition axis 4 12 with loose cutter pull bar 10 junctions, and transition axis 4 12 outsides are provided with loose knife oil cylinder piston 13.Wherein also be provided with O type circle four between splined shaft 1 and the transition axis 26, also be provided with O type circle 3 16 between splined shaft 27 and the transition axis 26, also be provided with O type circle one between transition axis 39 and the transition axis 4 12, also be provided with O type circle two between splined shaft 27 and the transition axis 39.
The utility model is when work, and main motor transfers torque on the splined shaft 1 through gearbox 1, and splined shaft 1 connects by spline housing 1 with splined shaft 27, and splined shaft 27 connects with main shaft 11 by spline housing 28.By above-mentioned splined shaft 1, splined shaft 27 and spline housing 1 and spline housing 28, moment of torsion is delivered on the main shaft 11.The loose cutter of main shaft is realized by loose cutter pull bar 10, transition axis 4 12, oil cylinder piston 13.During the pine cutter, oil cylinder piston 13 moves right, and by the flat key on the transition axis 4 12, promotion transition axis 4 12, loose cutter pull bar 10 move right together, thereby back down the spring-loaded pawl of loose cutter pull bar 10 right-hand members, finish loose cutter.The tension of cutter is to realize by butterfly spring.
