For the locking signal supervisory instrument of numerically-controlled slide
Technical field
The present invention relates to a kind of locking signal supervisory instrument for numerically-controlled slide, belong to lathe saddle technical field.
Background technology
At present, the lathe saddle of prior art, in the time that locking gear ring engages with ring gear and external toothing, control system cannot know that whether it locks, and often occurs the phenomenon of maloperation.
Summary of the invention
Technical problem to be solved by this invention is the defect that overcomes prior art, and a kind of locking signal supervisory instrument for numerically-controlled slide is provided, and it can respond to lathe saddle in time whether in locking state, to improve the accuracy of lathe saddle transposition.
In order to solve the problems of the technologies described above, technical scheme of the present invention is: a kind of locking signal supervisory instrument for numerically-controlled slide, lathe saddle has locking gear ring, the external toothing being fixedly connected with upper knife body and the ring gear being fixedly connected with lower knife body, it comprises motor, deceleration device, tie down screw, locking signal screw, locking signal roundel and locking approach switch, motor is flexibly connected with the power shaft of deceleration device, the output shaft of deceleration device is flexibly connected with tie down screw by arrangement of clutch to drive tie down screw rotation, tie down screw is fixedly connected with locking gear ring, described locking signal screw is arranged on tie down screw, described locking signal roundel is arranged on tie down screw, and locking signal roundel matches with box lunch locking signal roundel and the induction of locking approach switch during with locking approach switch, locking gear ring and ring gear and external toothing is separated, lathe saddle is not in locking state, in the time that locking signal roundel and locking approach switch are non-inductive, lock gear ring and be meshed with ring gear and external toothing, lathe saddle is in locking state simultaneously.
Adopt after technique scheme, in the time of electric machine rotation, locking gear ring is because screw thread rotation moves up, locking gear ring and tie down screw are fixed together, locking signal screw also synchronously rises along with tie down screw rises, produce induced signal with locking approach switch, induced signal sends to system, in the time that blade holder turns arrives desired location, knife rest sends the signal that puts in place, motor reverse rotation, tie down screw moves down with locking gear ring simultaneously, with ring gear and external toothing locking, at this moment lock signal screw and be also moved down into the position that locking approach switch is not responded to, the system signal that loses induction, it is exactly knife rest locking state, at this moment system control knife rest motor stops operating, lathe is carried out next program.
Brief description of the drawings
Fig. 1 is the structural representation of the locking signal supervisory instrument for numerically-controlled slide of the present invention.
Detailed description of the invention
For content of the present invention is more easily expressly understood, according to specific embodiment also by reference to the accompanying drawings, the present invention is further detailed explanation below.
As shown in Figure 1, a kind of locking signal supervisory instrument for numerically-controlled slide, lathe saddle has locking gear ring 6, the external toothing 4 being fixedly connected with upper knife body 2 and the ring gear 3 being fixedly connected with lower knife body 1, it comprises motor 24, deceleration device 12, tie down screw 11, locking signal screw 13, locking signal roundel 14 and locking approach switch 18, motor 24 is flexibly connected with the power shaft of deceleration device 12, the output shaft of deceleration device 12 is flexibly connected with tie down screw 11 by arrangement of clutch 10 to drive tie down screw 11 to rotate, tie down screw 11 is fixedly connected with locking gear ring 6, locking signal screw 13 is arranged on tie down screw 11, locking signal roundel 14 is arranged on tie down screw 11, and locking signal roundel 14 matches with locking approach switch 18 and while responding to locking approach switch 18 with box lunch locking signal roundel 14, locks gear ring 6 and ring gear 3 and external toothing 4 and be separated, lathe saddle is not in locking state, in the time that locking signal roundel 14 and locking approach switch 18 are non-inductive, lock gear ring 6 and be meshed with ring gear 3 and external toothing 4, lathe saddle is in locking state simultaneously.
Operation principle of the present invention is as follows:
In the time that motor 24 rotates, locking gear ring 6 is because screw thread rotation moves up, locking gear ring 6 is fixed together with tie down screw 11, locking signal screw 13 also synchronously rises along with tie down screw 11 rises, produce induced signal with locking approach switch 18, induced signal sends to system, in the time that blade holder turns arrives desired location, knife rest sends the signal that puts in place, motor 24 counter-rotates, tie down screw 11 moves down with locking gear ring 6 simultaneously, lock with ring gear 3 and external toothing 4, at this moment lock signal screw 13 be also moved down into locking approach switch 18 not have respond to position, the system signal that loses induction, it is exactly knife rest locking state, at this moment system control knife rest motor stops operating, lathe is carried out next program.
Above-described specific embodiment; technical problem, technical scheme and beneficial effect that the present invention is solved further describe; institute is understood that; the foregoing is only specific embodiments of the invention; be not limited to the present invention; within the spirit and principles in the present invention all, any amendment of making, be equal to replacement, improvement etc., within all should being included in protection scope of the present invention.
