Description of the drawings
Fig. 1 is the flow diagram of apparatus of the present invention.
Specific embodiment
The flow diagram of the present invention is as shown in Figure 1.Referring to Fig. 1, the tool guard for depth drill is served as reasons
The control device that detection module, selection judgment module, execution module and process record module form, whole system can be realized to depth
It is provided protection against during hole drill machine cutter on-line machining.
Data acquisition module can be realized carries out on-line checking to the load of deep hole drilling machine drilling rod rotation (main cutting force), simultaneously
It needs the data of detection be adapted for the standard automatic analog amount input value of DC0~5V, DC0~10V, DC4~20mA, makees
Data acquisition module for whole device.
Selecting module is based on previous stage detection module input signal.By classification, born with the processing for being adapted to different
Lotus (processing object, processing technology)；It is carried out at the same time and compares, select the reference value of corresponding level, as a reference value, with being adopted by data
Collect the input signal of module, by comparing, see if fall out, if exceeding, export to the execution module of rear class.
Execution module selects the output signal of judgment module according to previous stage, performs respective action.If obtaining output signal,
Outputting cutting breaking of rod bar cutting feed signal, while export alarm.Deep hole drilling machine enters emergency stop conditions when necessary.It can also root
All kinds of actions are exported/perform according to customer requirement.
Process record module carries out cycle index to the data of whole system, and can provide the output function of record data,
For off line data analysis.
Specifically：
The data acquisition module of device is detected the load of deep hole drilling machine drilling rod rotation (main cutting force), mainly adopts
Collect the current value of drilling rod rotation (main cutting force).Its practical application is determined according to lathe configuring condition：If general control, it can
To use (installation) current sensing means；According to DC speed regulation/variable frequency regulating speed control, may be used directly from direct current tune
Speed/frequency converter obtains current data.It is real by obtaining simultaneously according to the range of the selection determination module of practical rear stage
When current data be adapted for input signal (type and range) needed for system：Such as DC0~5V, DC0~10V, DC4~
20mA。
The selection judgment module of device is divided into as selection (classification) module and judgment module.It is root to select (classification) module
According to processing features, work hour load will be added to be divided into several grades, to gate corresponding comparison module, realize suitable reference value
Compare；The circuit that judgment module is gated according to selection (classification) module, using preset reference value as comparison value, is sentenced
It is fixed whether abnormal load occur.Simultaneously in practical applications to prevent instantaneous abnormal load caused by accelerating, slow down or interfering, and
Delay filtering module has been installed in caused malfunction additional, to ensure the correct effective of input signal.It can be more for operation/maintenance personnel
Actual loading (electric current) is got information about and grasps, the numerical value of the existing current value of module of selection shows that also column shows (phase
For nominal load/electric current of motor), visualization is preferable.
The execution module of device, mainly according to previous stage selection judgment module as a result, performing action needed for output.One
As be feed-disabling.It can also stop all movements (being rotated including main shaft) according to requiring；Into emergency stop conditions；It is defeated
Go out and keep the various motions such as alarm (sound-light alarm), play a warning role.And execution action/alarm can be kept as needed
Until personnel intervene manually.
The process record module of device can be acquired each type load/current value, it might even be possible to record gear signal
Etc. a variety of real-time status, and cycle storage is carried out, as needed output record data, remotely to carry out off-line analysis,
It can be as the basic data of modified technique.The process record module has the display at a variety of interfaces simultaneously, and visualization is high.
The device can also create conditions to tool life management, provide tool wear --- the master data and pipe scrapped
Manage foundation.
In real case, the boring bar rotation actual current value of acquisition is direct by DC speed regulation/frequency converter
It obtains, i.e., is directly exported by it, while the signal of 0~10V of standard can be directly obtained by suitable parameter regulation, that is,
The signal converted.Data acquisition module is just embedded in original equipment in this way.
Meanwhile in real case, execution module selects the element acted using the original PLC of equipment as execution, leads to
It crosses the function addition to its original program and modification, realizes that photoelectric alarm, feeding stop and other desired perform action.This
Sample execution module is also embedded in original equipment.
In order to provide the output function of record data, for off line data analysis, selection attached process record module.
Actual current value, the signal of converted treated 0~10V of standard and other related datas are rotated by extracting boring bar
Signal, while can be with acquisition and recording some processes signal, such as selection gear signal etc..And it can will be recycled by USB interface
The off-line data of record is preserved and is analyzed.
To sum up, the tool guard takes full advantage of all kinds of electrical modules and component of original equipment, additional component
Few, small investment has been effectively accomplished the purpose for preventing deep hole drilling machine drill bit and drill pipe wear from protecting.With good visualization,
The scrappage of product is reduced, improves production efficiency.
The tool guard also can be according to live physical condition Adjusted Option, and adds or reduce function according to demand
With corresponding module.
The present invention claims protection domain be not limited only to above-described embodiment, should also include that other are obvious to the invention
Transformation and alternative solution.
