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
It controls before lathe saddle, and is electrically connected with controller, the driving motor is fixedly connected with the tailstock of numerically controlled lathe, and with
Controller 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 canine tooth
Wheel intermeshing;The cylinder is the adjustable finger-like cylinder of stroke, and the solenoid directional control valve control cylinder stretches.
The screw tap component includes screw tap and the fixture for clamping screw tap, and the fixture is mounted on numerically controlled lathe tailstock set
In cylinder.
When tapping, numerically controlled lathe saddle shifts to tailstock along Z-direction, and the sensor of the connecting pole shaft end and tailstock side is connected
When, controller sends out signal, and the movement of numerically controlled lathe saddle Z-direction is made to stop, and at the same time, work is entered on the left of solenoid directional control valve
Position makes the cylinder piston rod stretch out, and pushes rack to move forward, to drive bull gear drive, the cursor is made to be caught in
In the annular groove of connecting pole, saddle links into an integrated entity with tailstock at this time, and numerically controlled lathe carries out tapping operation by program;Tapping completion waits for
Screw tap exits completely, and after tailstock is moved to appropriate location, and controller sends out instruction, and controller sends out instruction, electromagnetic switch
Enter working position on the right side of valve, make cylinders retract, drives gear wheel reversion, to make cursor leave the annular groove of connecting pole, to
Complete disengagement action;When an unexpected situation occurs, the reset switch is pressed, controller resets.
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, to can realize float tapping;It utilizes
Cylinder realizes that saddle is engaged or disengaged with the automatic of tailstock, at low cost, and further improves the degree of automation of numerically controlled lathe,
Extend the function of numerically controlled lathe.

Specific implementation mode
It is a kind of to be used with the numerically controlled lathe tailstock auto-feed control method of float tapping with what cylinder drove
It is a kind of by cylinder realize numerically controlled lathe saddle and tailstock engagement with disengage attachment device, including connecting pole 1, rotation arm component,
The middle part of drive component and screw tap component, the connecting pole 1 is provided with an annular groove 3, and connecting pole 1 is fixed with numerically controlled lathe saddle to be connected
It connects, 1 shaft end of connecting pole and tailstock side are provided with a pair of sensors 13, and 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
