Description
Technical field
A kind of power-off protection method of the present invention for CNC toolroom machine and the circuit breaking protective system using it, more particularly to
The system of automatic withdrawal decision when CNC toolroom machine powers unstable.
Background technique
As shown in Figure 1, frequently thundering or the unstable area that power is easy to happen jump electricity, the generation that makes to power is asked
Topic, if CNC toolroom machine 1 stops power supply being worked into half suddenly, the cutter 11 on rotary tool axis 10 can be because suddenly
Power-off, brake also do not clamp before just fall, not only result in the table that cutter 11 directly impinges workpieces processing 12 in this way
Face makes 11 service life reduction of cutter, even damages, and processing lines can be also left in workpieces processing 12, and then make workpieces processing
12 surface smoothness reduction, or even become waste product, and multi-step process perhaps performed in this way is all by all that has been achieved is spoiled.At present
The solution proposed in response to the above problem is that when power is off, CNC toolroom machine just directly executes power-off cutter lifting.
However, in the actual processing process, the knife tower of CNC toolroom machine often has much knives perhaps, the kenel of some cutters
It is suitble to power-off cutter lifting (outer circle tool for cutting machining as shown in Figure 2) during processing, some cutters are not appropriate for power-off lift
Knife (molding cutter shown in tapping cutter as shown in Figure 3, Fig. 4 and another molding cutter shown in Fig. 5).If being used when processing
Cutter be tapping knife or forming cutter, CNC toolroom machine but but carries out cutter lifting when power is off, it would be possible to can damage rotary tool axis,
Cutter or workpiece.
Summary of the invention

Among the remote server of first 24 lines.In this way, which user can update directly on CNC toolroom machine or modify storage element
Data in 23, or CNC toolroom machine is uploaded to after the data of update or modification storage element 23 in remote server.It is worth
It is noted that being suitble to or being not suitable for executing the cutter of cutter lifting when user in storage element 23 in addition to that can establish power supply shakiness
Kenel and the processing program table of comparisons and cutter lifting distance are outer.On the other hand, user can also set machine in storage element 23
Structure parameter (such as mechanism coupled pattern and screw rod pitch) and trajectory parameters (such as gravity direction, highest momentum and highest acceleration),
With sharp CNC control unit 24 planning cutter lifting speed and cutter lifting direction.
In one embodiment, CNC control unit 24 includes the processing on real-time state of record CNC toolroom machine in storage element
23, and in CNC toolroom machine telegram in reply, continue to process in the instantly unfinished Working position of power-off.For example, work as CNC
Control unit 24 obtain power-off warning signal 251 after, can by the machining state of CNC toolroom machine instantly (such as work pieces process situation or
Tool position) it is recorded in storage element 23, it, can be according to the record information in storage element 23 after subsequent CNC toolroom machine telegram in reply
Connect processing flow.In another embodiment, CNC control unit 24 can also be periodically (as often without acquirement power-off warning signal 251
Interval 3 seconds) or not timing (as interval 1 second, 5 seconds with 7 seconds) in CNC tool machining process record machining state in storage
Unit 23 can adjust at any time the record time according to user's demand.
(equally please refer to Fig. 6, Fig. 7 or Fig. 8) in one embodiment, the circuit breaking protective system 2 of the CNC toolroom machine further includes
One power quality monitoring unit 25 is to couple with the CNC control unit 24, to monitor the power supply of the CNC toolroom machine in real time
Quality, and lower than a preset value, (electric power of generally supply CNC toolroom machine drops to nothing in the power supply quality of the CNC toolroom machine
Faville holds the numerical value of proper operation, and only the preset value does not set logic with this and is limited) below when, issue the power-off warning signal
251.The power supply quality of the CNC toolroom machine includes any factor for extrapolating power supply content in aforementioned, such as power instantly
Voltage value or the current value powered instantly.In one embodiment, it is single can be mounted to CNC control for power quality monitoring unit 25
The power quality monitoring programme of (as shown in Figure 6) in first 24 (as shown in Figure 7) or driver 21；In another embodiment, electric power
Quality monitoring unit 25 is also possible to be external in the hardware device (as shown in Figure 8) of CNC control unit 24 or driver 21, this hair
It is bright without restriction to this.
In one embodiment, which judges that the circuit breaking protective system 2 of the CNC toolroom machine instantly is suitble to hold
The condition of row cutter lifting protective program includes to meet following to begin to set up: 1. obtain the institute instantly of the power-off warning signal 251 into
The cutter kenel of the capable processing program be suitably executed cutter lifting protective program, 2. obtain the power-off warning signal 251 instantly into
The capable processing program be suitably executed cutter lifting protective program and 3. obtain the power-off warning signal Working position instantly should
Cutter lifting distance does not exceed the extreme limit of travel of the board, and detailed description are as follows.
For example, when the power supply quality of CNC toolroom machine is unstable, CNC control unit 24 can obtain power-off warning news
Numbers 251, if CNC toolroom machine uses external cutting process tool to the judgement of CNC control unit 24 instantly, represent above-mentioned 1st
Condition is set up；If CNC control unit 24 judges that execute instantly is external cutting processing program, represent above-mentioned 2nd condition at
It is vertical；If the judgement of CNC control unit 24 does not instantly exceed the cutter lifting distance that external cutting process tool lifts preset
Board extreme limit of travel represents above-mentioned 3rd condition and sets up.CNC control unit 24 is the case where above-mentioned 1~3 condition is all set up
Under, judge that the circuit breaking protective system 2 of CNC toolroom machine is suitably executed cutter lifting protective program, CNC control unit 24 can issue cutter lifting life
It enables and gives rotary tool axis motor driver.
In one embodiment, which judges that the circuit breaking protective system 2 of the CNC toolroom machine instantly is suitble to hold
The condition of the row brake program includes to meet any one of following to set up: 1. obtain the power-off warning signal 251 instantly into
The cutter kenel of the capable processing program is not suitable for executing cutter lifting protective program, 2. obtains the progress instantly of the power-off warning signal
The processing program be not suitable for execute cutter lifting protective program or 3. obtain the power-off warning signal Working position instantly lift
Knife distance is more than the extreme limit of travel of the board, and detailed description are as follows.
For example, when the power supply quality of CNC toolroom machine is unstable, CNC control unit 24 can obtain power-off warning news
Numbers 251, if CNC toolroom machine uses the cutters such as molding, tapping or drilling to the judgement of CNC control unit 24 instantly, represent above-mentioned
1st condition is set up；If what CNC control unit 24 judged to execute instantly is the processing programs such as molding, tapping, drilling or fishing side,
Above-mentioned 2nd condition is represented to set up；If CNC control unit 24 judges the lift for instantly lifting the cutters such as molding, tapping or drilling
Knife distance can be more than preset board extreme limit of travel, represent above-mentioned 3rd condition and set up.CNC control unit 24 is above-mentioned 1
In the case that any one of~3 conditions are set up, judge that the circuit breaking protective system 2 of CNC toolroom machine is suitably executed brake program, CNC
Control unit 24 can issue the driver 21 ceased and desisted order to rotary tool axis motor.
During the circuit breaking protective system of the CNC toolroom machine of the preceding description present invention, also illustrate the present invention's simultaneously
