Detailed description of the invention
By describe in detail the present invention technology contents, structural feature, reached object and effect, below hereby exemplify embodiment and coordinate accompanying drawing to be explained in detail.
Refer to Fig. 1, and in conjunction with consulting shown in Fig. 2, the invention provides a kind of numerical control chuck 10 with automatic key locking device, comprise chuck 10, lowering or hoisting gear 20, locking device 30, wherein, chuck 10 is provided with keyhole 11, and this chuck 10 comprises the claw 12 for clamping work pieces; Locking device 30 is arranged on lowering or hoisting gear 20, can under the driving of lowering or hoisting gear 20, move up and down by relative chuck 10; Locking device 30 comprise match with keyhole 11 determine moment of torsion key 31, drive motors 32, the output shaft of drive motors 32 is determined moment of torsion key 31 with this and is connected, and inserts keyhole 11 when interior when determining moment of torsion key 31.Drive motors 32 can drive determines moment of torsion key 31 in the interior rotation of keyhole 11, to drive claw 12 tensionings of locking device 30 or to unclamp.
In the time of chuck 10 normal work, determining moment of torsion key 31 separates with keyhole 11, chuck 10 clamping work pieces High Rotation Speeds, in the time that needs are changed on chuck 10 clamping work pieces, lowering or hoisting gear 20 drive installations locking device 30 thereon moves upward, when locking device 30 determine moment of torsion key 31 insert keyhole 11 interior after, drive motors 32 drivings are determined moment of torsion key 31 and are rotated, drive claw 12 to unclamp and unload workpiece or tension clips clamping of workpieces by determining the motion of moment of torsion key 31, realize the mechanization tensioning of claw 12 and unclamp, adopt and manually twist keyhole 11 by spanner with tradition, drive clamps tensioning and compares with unclamping, it is more time saving and energy saving, and there is good control to determining the degree of tightness dynamics that moment of torsion key 31 turns, can effectively prevent excessive tightening or unscrew, cause the excessive meshing wear of its internal mechanical parts, affect its service life.
Shown in Fig. 2, lowering or hoisting gear 20 of the present invention comprises fixed head 21, installing plate 22, driving cylinder 23, driving cylinder 23 is fixed on installing plate 22, the expansion link of this driving cylinder 23 is connected with fixed head 21, in the time that expansion link shrinks, can drive the relatively described fixed head 21 of driving cylinder 23 to move up and down, preferred, this driving cylinder 23, for driving cylinder, drives expansion link and the fixed head 21 of cylinder to be fixedly linked; Locking device 30 also comprises an adapter sleeve 33, and the periphery of this adapter sleeve 33 is provided with two chutes 34 that are relatively waist-shaped hole shape, the output shaft of drive motors 32 is connected with these adapter sleeve 33 one end by two bolts through chute 34, and these adapter sleeve 33 other ends with determine moment of torsion key 31 and be fixedly linked, drive motors 32 is fixedly installed on installing plate 22.
When work, driving cylinder 23 orders about expansion link and shrinks, because the external part of expansion link is fixed on fixed head 21, therefore, force the relative fixed head 21 of installing plate 22 to move upward, thereby drive the drive motors 32 being arranged on installing plate 22 to move upward, in drive motors 32 motion processes, the output shaft of drive motors 32 is at the interior relative sliding of chute 34 of adapter sleeve 33, in the time that the output shaft of drive motors 32 moves to the peak of chute 34, ordering about adapter sleeve 33 drives and determines moment of torsion key 31 and move upward, stretch in keyhole 11, drive motors 32 drives are determined moment of torsion key 31 and are rotated, thereby realize the control of claw 12, otherwise, when claw 12 reaches work and meets the requirements, driving cylinder to order about expansion link extends, force the relative fixed head 21 of installing plate 22 to move downward, move downward thereby drive to be arranged on the drive motors 32 on installing plate 22 and to determine moment of torsion key 31, exit keyhole 11.
Shown in Fig. 2, if a kind of numerical control chuck 10 with automatic locking device 30 of the present invention, on this fixed head 21, be also provided with a buffer 25, buffer 25 is arranged on fixed head 21 near installing plate 22 one end, and a guide cylinder 24 is also housed on this fixed head 21, this guide cylinder 24 is symmetrical arranged with driving cylinder, and the expansion link of guide cylinder 24 stretches out and passes this fixed head 21.The flexible relative fixed head 21 of installing plate 22 that drives of expansion link at driving cylinder 23 moves up and down in process, due to the expansion link effect of guide cylinder, force in its motion process and do not produce and rock, anti-fastening moment of torsion key 31 departs from keyhole 11, affect its use, simultaneously, under the effect of buffer 25, make the relative motion between installing plate 22 and fixed head 21 comparatively slow, thereby making to determine moment of torsion key 31 enters in the process in keyhole 11, can not bump, anti-fastening moment of torsion key 31 collides impaired.
Keep corresponding in order to ensure keyhole 11 with the relative position of determining moment of torsion key 31, on chuck 10, be provided with the inductive switch 13 of determining moment of torsion key 31 relative positions for calibrating keyhole 11 and this; Further on this installing plate 22, be provided with for detection of installing plate 22 approach switch 27 with fixed head 21 relative positions, fixed head 21 is provided with the inductor 26 interacting with approach switch 27.
As preferred version of the present invention, in order further to realize automation of the present invention, numerical control chuck 10 of the present invention also comprises a controller, this driving cylinder 23, drive motors 32, inductor 26, inductive switch 13 are connected with this controller respectively, and user can control by controller automated programming or manually the automatically working of realizing numerical control chuck 10.
In sum, be only the present invention's preferred embodiment, do not limit protection scope of the present invention with this, all equivalences of doing according to the scope of the claims of the present invention and description change and modify, within being all the scope that patent of the present invention contains.
