Device.
The rotation arm component includes cursor, rotation axis, axle sleeve and gear wheel, and the axle sleeve is fixed on numerical control lathe tailstock
On the leading flank of seat, the rotation axis passes through axle sleeve, rotation axis front end to be fixedly connected with cursor, the other end and the gear wheel
It is fixedly connected, the front end of cursor, which is provided with one, can be caught in the hook portion of annular groove.
The driving component includes rack, cylinder, solenoid directional control valve, rack guide groove, reset switch and controller, described
Controller is mounted in lathe power distribution cabinet and is electrical connected with digital control system and solenoid directional control valve, and the reset switch is mounted on number
Control before lathe saddle, and be electrically connected with controller, driving motor is fixedly connected with the tailstock of numerically controlled lathe, and with control
Device is electrically connected, and the rack is fixed on the front end of the cylinder, and rack is mounted in guide groove, the rack and gear wheel phase
Mutually engagement;The cylinder is the adjustable finger-like cylinder of stroke, and the solenoid directional control valve control cylinder stretches.
When numerically controlled lathe saddle needs to engage with tailstock, numerically controlled lathe saddle shifts to tailstock, the connecting pole along Z-direction
When the sensor of shaft end and tailstock side is connected, controller sends out signal, and numerical controlled lathe Z is made to stop to mobile, at the same time, electricity
Enter working position on the left of magnetic reversal valve, the cylinder piston rod is made to stretch out, pushes rack to move forward, to drive canine tooth to rotate
It is dynamic, so that the cursor is caught in the annular groove of connecting pole, joint action is completed;When numerically controlled lathe saddle needs to disengage with tailstock
When, the reset switch is pressed, controller sends out instruction, enters working position on the right side of solenoid directional control valve, make cylinders retract, drives big
Gear inverts, to make cursor leave the annular groove of connecting pole, to complete disengagement action.
The present invention is by using the technique effect of said program, using between the connecting pole and tailstock being fixedly connected with saddle
Sensor judge relative position between the two, no matter automatic connection between the two wherein can be achieved in tailstock, improves
The flexibility connected between the two;The mutual clamping of annular groove of the front end hook portion and connecting pole of cursor, realizes saddle and tailstock
Synchronizing moving, keep tailstock kinematic accuracy consistent with the Z-direction kinematic accuracy of numerically controlled lathe, add so as to accurately control hole class
The dimensional accuracy of working hour length direction;It realizes that saddle is engaged or disengaged with the automatic of tailstock using cylinder, further improves number
The degree of automation for controlling lathe, extends the function of numerically controlled lathe.

Specific implementation mode
A kind of numerically controlled lathe tailstock feed control method uses a kind of cylinder to realize numerically controlled lathe saddle and tailstock
Engagement and the attachment device disengaged, including connecting pole 1, rotation arm component and drive component, the middle part of the connecting pole 1 are provided with
One annular groove 3, connecting pole 1 are fixedly connected with numerically controlled lathe saddle, and 1 shaft end of connecting pole and tailstock side are provided with a pair of sensors
13, the sensor can be magnetic effect sensor or hall effect sensor, can also be photoelectric sensor.
The rotation arm component includes cursor 4, rotation axis 5, axle sleeve 6 and gear wheel 7, and the axle sleeve 6 is fixed on numerical control
On the leading flank of tail stock, the rotation axis 5 passes through axle sleeve 6, and 5 front end of rotation axis is fixedly connected with cursor 4, the other end and
The gear wheel 7 is fixedly connected, and the front end of cursor 4, which is provided with one, can be caught in the hook portion of annular groove 3.
The driving component includes rack 2, cylinder 8, solenoid directional control valve 9, rack guide groove 10, reset switch 14 and control
Device 15, the controller 15 are mounted in lathe power distribution cabinet and are electrical connected with digital control system and solenoid directional control valve 9, the reset
Switch 14 is mounted on before numerically controlled lathe saddle, and is electrically connected with controller 15, the tailstock of driving motor and numerically controlled lathe
