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
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.
When numerically controlled lathe saddle needs to engage with tailstock, numerically controlled lathe saddle shifts to tailstock along Z-direction, described to axis axis
When the sensor at end and tailstock side is connected, controller sends out signal, and the movement of numerically controlled lathe saddle Z-direction is made to stop, at the same time,
Enter working position on the left of solenoid directional control valve, the cylinder piston rod is made to stretch out, pushes rack to move forward, to drive gear wheel
Rotation, makes the cursor be caught in the annular groove to axis, and 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 to axis, to complete disengagement action.
The present invention is by using the technique effect of said program, using between saddle and tailstock to axis and V-block
It realizes centering between the two, judges whether front-rear direction position is correct between the two;Judge phase between the two using sensor
To position, no matter automatic connection between the two wherein can be achieved in tailstock, improves the flexibility connected between the two;Turn
The front end hook portion of swing arm realizes the synchronizing moving of saddle and tailstock with to the mutual clamping of the annular groove of axis, makes tailstock movement essence
Degree is consistent with the Z-direction kinematic accuracy of numerically controlled lathe, the dimensional accuracy of length direction when so as to accurately control hole class processing;Profit
It realizes that saddle is engaged or disengaged with the automatic of tailstock with cylinder, further improves the degree of automation of numerically controlled lathe, extend
The function of numerically controlled lathe.

Specific implementation mode
A kind of numerically controlled lathe tailstock control method with V-block centering uses a kind of cylinder to realize numerically controlled lathe
The attachment device of saddle and tailstock engagement and disengagement, including centering component, rotation arm component and drive component, the centering component
It is V-shaped close to the axial end portion setting of tailstock to axis 1 including to axis 1 and V-block 16, to axis and numerically controlled lathe saddle
It is fixedly connected, V-block 16 is horizontally mounted and is fixedly connected with numerically controlled lathe tailstock, to the front end V-type part of axis 1 and is caught in institute
It states V-block 16 and realizes lathe front-rear direction centering, a pair is provided with close to the end face of tailstock side and 16 bottom of V-block to axis 1
Sensor 13, the sensor 13 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 driving motor and numerically controlled lathe
Tailstock is fixedly connected, and is electrically connected with controller 15, and the rack 2 is fixed on the front end of the cylinder 8, and rack 2 is mounted on

When numerically controlled lathe saddle needs to engage with tailstock, numerically controlled lathe saddle shifts to tailstock along Z-direction, described to axis 1
When the sensor 13 of shaft end and tailstock side is connected, controller 15 sends out signal, and the movement of numerically controlled lathe saddle Z-direction is made to stop, with
This enters working position simultaneously on the left of solenoid directional control valve 9,8 piston rod of the cylinder is made to stretch out, and rack 2 is pushed to move forward, thus
It drives gear wheel 7 to rotate, the cursor 4 is made to be caught in the annular groove to axis 1, joint action is completed;When numerically controlled lathe saddle
When needing to disengage with tailstock, the reset switch 14 is pressed, controller 15 sends out instruction, and 9 right side of solenoid directional control valve enters work
Position makes cylinder 8 retract, and gear wheel 7 is driven to invert, dynamic to complete to disengage to make cursor 4 leave the annular groove to axis 1
