As a further improvement on the present invention, the tailstock main shaft often rotates a circle, and rotating monitoring switch sends a master
Axle rotating signal.
As a further improvement on the present invention, the PLC module is S7-300PLC modules.
The beneficial effects of the present invention are：
The present invention is being switched and is being opened on tailstock main shaft by the rotating monitoring on the end cap of barrel of tail stock
Detection hole, in equipment process, can detect the rotation of main shaft, and main shaft rotating signal is delivered into PLC module, write
PLC program makes PLC module control spindle motor to rotate by digital control system, and when occurring abnormal, energy automatic stopping, is avoided great
The generation of accident；Meanwhile after main shaft rotating signal delivers to PLC module, with PLC program PLC module can be made to pass through numerical control
System control display screen display alarm information, add the warning function to position protection；In addition, the present invention can be combined with
The workpiece pre-tightening force signal of tailstock pressure display device, judges whether workpiece holds out against, when main shaft is dallied because debugging, repairing
Do not influenceed by apparatus of the present invention, and the present invention can play automatic monitoring, the effect of protection parking after clamping workpiece.
Brief description of the drawings
In order that the purpose of the present invention, technical scheme and beneficial effect are clearer, the present invention provides drawings described below and carried out

Embodiment
Below in conjunction with accompanying drawing, the preferred embodiments of the present invention are described in detail.
Fig. 1 is that the lathe centre of the present invention rotates the structural representation of real time monitoring apparatus, as illustrated, a kind of lathe top
Point rotation real time monitoring apparatus, including rotating monitoring switch on the end cap 2 of barrel of tail stock 13 and are opened in tailstock master
Detection hole 5 on axle 4, the face rotating monitoring of detection hole 5 switch 3, the rotating monitoring switch 3 send main shaft rotating signal
To PLC module 6, PLC module 6 controls spindle motor 8 to rotate by digital control system 7（9 be tailstock body in figure, and 10 be top）.
In equipment process, after PLC module 6 detects main shaft rotating signal exception, PLC module 6 is controlled by digital control system 7 and led
Spindle motor 8 is shut down, and avoids the generation of major accident.
In order to increase the warning function to position protection, main shaft rotating signal is delivered to PLC by the rotating monitoring switch 3
Module 6, PLC module 6 pass through the display alarm information of 7 control display screen of digital control system 11.In equipment process, PLC module 6
After detecting main shaft rotating signal exception, PLC module 6 is alarmed by the control display screen 11 of digital control system 7, reminds operator immediately
Shut down, if information is ignored, spindle motor 8 is shut down in reminder time after.
Tailstock pressure display device 12 is also equipped with tailstock body 9, be provided with barrel of tail stock 1 displacement transducer or
Workpiece pre-tightening force signal is delivered to tailstock pressure display device 12, tail by pressure sensor, displacement transducer or pressure sensor
Workpiece pre-tightening force signal is delivered to PLC module 6 by seat pressure display device 12, and PLC module 6 combines workpiece pre-tightening force signal, sentenced
Whether disconnected workpiece holds out against, and is not influenceed when main shaft is dallied because debugging, repairing by apparatus of the present invention, and after clamping workpiece originally
Invention can play automatic monitoring, the effect of protection parking.
