Bed internal spindle and bearing etc. precise part are damaged；There is portions of client that cutter is removed, workpiece is dismantled, after scene is cleaned out
Do not recognize to collide, it is desirable to which lathe producer is undertaken because of the maintenance cost produced by client's maloperation, can be brought very to lathe producer
More unnecessary maintenance cost.On the other hand, just in case genuine clash into because of equipment fault or human error in operation,
If equipment does not have the lock out action of next step, it is likely that result in greater loss.
Therefore, it is necessary to be protected to the Digit Control Machine Tool scene of colliding.
The content of the invention
The purpose of the present invention：To solve because of the responsibility decision problem that client's maloperation is produced, it is to avoid lathe producer is unnecessary
Maintenance cost, also for avoiding after clashing into bigger loss, it is necessary to invent a kind of control of the scene protection that collided for Digit Control Machine Tool
System and method processed, judges that the lathe that collides and lock immediately occurs in machine in time, reaches the purpose of the loss that keeps the scene intact, avoids.
To reach above-mentioned purpose, technical scheme is as follows：
A kind of control system of the scene protection that collided for Digit Control Machine Tool, including it is stored in the master inside Digit Control Machine Tool PLC
Spindle motor current detecting subprogram 1, current break judges subprogram 2 and machine tool action locking subprogram 3,
The current of spindle motor detects subprogram 1, for the monitor in real time main shaft during Digit Control Machine Tool reality processing
The current value of motor；
The current break judge subprogram 2 for pre-set current break threshold values and in real time with the electric current of spindle motor
Value is compared and judges, and locks subprogram (3) output lock control signal to the machine tool action；
The machine tool action locks the locking control that subprogram (3) judges subprogram (2) for receiving the current break
Signal simultaneously locks the everything of lathe.
This method also discloses a kind of control method of the scene protection that collided for Digit Control Machine Tool simultaneously, and its step includes：
(a) described the current of spindle motor detection subprogram 1, during Digit Control Machine Tool reality processing, monitor in real time main shaft
The current value of spindle motor is simultaneously sent to the current break and judges subprogram 2 by the current value of motor in real time；
B () described current break judges subprogram 2 by the current value of spindle motor and the internal current break for pre-setting
Threshold values is compared and judges in real time,
If b1. the electric current moment increment value of spindle motor is not above the current break threshold values for setting, lathe is normally transported
Turn；
If b2. the electric current moment increment value of spindle motor exceedes the current break threshold values for setting, into step (c)；
C () described current break judges that lock control signal is sent to the machine tool action locking subprogram by subprogram 2
3, the machine tool action locking subprogram 3 enters state of activation, locks the everything of lathe, keeps current state；
D () lathe institute is functional to be in the lock state and is provided with cryptoguard, it is necessary to by machine tool plant authorized person by close
Code unblock simultaneously could close the state of activation that the machine tool action locks subprogram 3.
Beneficial effects of the present invention：The change of this control system and method according to the current of electric for clashing into main shaft in generating process
Change characteristic to determine whether the generation that collides, if it is determined that the current of electric change of main shaft meets the feature that collides and judges that lathe goes out
Now collide, and starter motor bed action locking subprogram locks lathe everything immediately, has reached the purpose for keeping the scene intact, energy
It is prevented effectively from after clashing into bigger loss and avoids the unnecessary maintenance cost of lathe producer.
Brief description of the drawings
Fig. 1 is the schematic flow sheet of the control method of scene protection that collided for Digit Control Machine Tool described in this method.
Corresponding component title in figure represented by numeral：
1. the current of spindle motor detection current break of subprogram 2. judges that the machine tool action of subprogram 3. locks subprogram.
Specific embodiment
The invention provides a kind of control system and method for the scene protection that collided for Digit Control Machine Tool, machine is used in client
During bed, the current value of monitor in real time spindle motor, and instantaneous variation amount and the hair that collides according to the current of spindle motor
The current of spindle motor variation characteristic during life determines whether the generation that collides, if it is judged that to collide, then directly
Locking lathe reaches the purpose at the protection scene of colliding.
This control method is described in further detail with reference to embodiment and accompanying drawing.
