Sign is the main shaft output end chuck for installing on the left of lathe bed, and right side is tail platform part, the tail platform component level axle relative with chuck
To there is top, top to have blade carrier component；Tail platform part is fixed on tail stage body, tail stage body be arranged on leading screw on, leading screw parallel to
Main shaft is arranged on lathe bed bottom, and left end is fixed on bearing block, right-hand member and motor cabinet, servomotor connect；Tail platform is electrically set：
Lathe front installation CNC operating desks, by bus EtherCAT connection servo-drivers, servomotor passes through motor encoder electricity
Cable, motor power cable are connected with servo-driver respectively；Servomotor driving tail platform control parameter by CNC operating desks to
Lathe control system PLC inputs are set；Digital control system is communicated in the form of bus with driver, control model have mode position and
Torque mode, leading screw rotation is driven to drive tail platform to move, top tight workpiece or rollback.
Beneficial effects of the present invention：Using said structure and control system, it is possible to achieve hold out against the high low velocity of process certainly
Dynamic to switch, position is verified after top tight workpiece, and retracted position is accurately positioned, the function such as real-time switching control of motor position, moment of torsion, both
The efficiency that is loaded of tail platform can be improved can ensure the safety that is loaded of tail platform again.

Embodiment
The numerical control lathe tailstock platform of this servomotor driving of the present invention, including lathe PLC control system, servomotor, silk
Thick stick, as shown in figure 1, installing matrix of the lathe bed 1 as each part, it is characterised in that in the output end installation card of 1 left side main shaft of lathe bed 2
Disk 5, right side are tail platform parts 3, and tail platform part 3 horizontal axis relative with chuck 5 has top 9, top to have blade carrier component 4；See
Fig. 2, tail platform part 3 is fixed on tail stage body 10, tail stage body 10 is arranged on leading screw 8, and leading screw 8 is arranged on bed parallel to main shaft 2
The bottom of body 1, left end is fixed on bearing block 7, right-hand member and motor cabinet 11, servomotor 12 connect；Reductor 6 will be main by belt
The power of axle 2, which passes to, drives leading screw 8.Tail platform, which is electrically set, sees Fig. 3, lathe front installation CNC operating desks 13, passes through EtherCAT
Bus 14 connects servo-driver 15, and servomotor 12 is by motor encoder cable 17, motor power cable 16 respectively with watching
Take driver 15, servomotor 12 connects.
The control parameter of servomotor driving tail platform is set：Inputted and joined to lathe control system PLC by CNC operating desks 13
Number is set, as shown in Fig. 4 tables：Torque unit 0101N.m rapid traverses speed F1, F2 and to trim speed unit be mm/min,
Hold out against positive and negative unit of error and hold out against position coordinates, speed switching coordinate, rollback coordinate, just spacing coordinate, negative spacing coordinate list
Position is mm.Digital control system is communicated in the form of bus with the driver of servomotor, and control model includes mode position and torsion
Square pattern.Digital control system control lathe servomotor 12 drives tail platform part 3, and servomotor 12 drives leading screw 8 to rotate to drive
Tail platform part 3 advances or retreated, and then holds out against or discharge workpiece.
The tail platform drive control course of work of the present invention is as follows：See flow chart 5,
Tail platform is implemented to hold out against action
System is position control mode, controls servomotor 12 to drive leading screw 8 with the fast speed of setting after reading parameter
F1 is moved to " speed switching coordinate ", and leading screw driving tail stage body 10 is fed back by servomotor built-in encoder to workpiece motion s,
Real-time test position and speed, after moving to default " speed switching coordinate ", system switches to torque control mode, controls servo
Motor 12 drives leading screw 8 to be rotated by the slower speed of setting with closing speed F2, and leading screw 8 drives tail platform 3 to continue to move to workpiece,
Until top 9 top tight workpiece meet obstructions after, lifting moment of torsion is when reaching the torque value of setting, if judging that current location is not being set
In the range of putting, then have and alarm and stop acting, if current location is in the range of setting, servomotor 12 keeps permanent moment of torsion defeated
Go out, tail platform holds out against action and completes and keep.
Motor torque switches in real time：System is under torque mode, and after tail platform top tight workpiece, the output torque of motor can be with
The setting value of system switches in real time.
Tail platform fallback action, is shown in flow chart 6：
Control system judges that tail platform fallback action starts according to parameter is read, and end holds out against dynamic and in-position control mould
Formula, control servomotor 12 drive leading screw 8 to be rotated with the very fast F1 speed of setting, and leading screw driving tail stage body 10 is retreated to " rollback
Coordinate ", fed back by servomotor built-in encoder, real-time test position and speed, if current location is not setting scope
It is interior, send alarm stopping action, after predeterminated position is moved to, motor stop motion and one fixed load of application ensures that motor is quiet
Only, keep rollback state tail platform to hold out against action to complete.
The motor driver 15 of tail platform is controlled by the programmable logic controller (PLC) of system, and tail platform axle can be with Z axis, X
Axle acts simultaneously.
