Accompanying drawing explanation
Below, understand the present invention further by reading detailed description considered in conjunction with the accompanying drawings, accompanying drawing comprises:
Fig. 1 is the schematic block diagram of the control fitting for annular saw according to an embodiment of the invention; And
Fig. 2 is the flow chart of the operation of control fitting.
Detailed description of the invention
Below, annular saw according to a preferred embodiment of the present invention will be described referring to Fig. 1.
Annular saw of the present invention comprises the control fitting of various cutting parameters, such as current Cutting Length for setting, measuring, show and control annular saw and total Cutting Length, cutting speed etc.
As shown in Figure 1, control fitting comprises:
CPU1; With
The start stop apparatus 2 be all connected with CPU1, range sensor 3, display 4, electric energy supply control unit 5, keyboard 6, siren 7 etc.
CPU1 be for from other components receive information/to other components send order single-chip element.CPU1 has timer or timer sum counter.
Start stop apparatus 2 can be mechanical type start stop apparatus or electric start stop apparatus, and can by user start come saw blade cutting movement and simultaneously start range sensor 1.
Range sensor 3 can be touch sensor or the noncontacting proximity sensor of Cutting Length for measuring saw, and pulse signal is sent to CPU1.This range sensor can use the sensor of any type commonly known in the art, such as, and photo-electric range sensor, ultrasonic distance sensor, laser distance sensor etc.
Display 4 can show input and output data and the operating parameter of saw.
Electric energy supply control unit 5 is connected between the power supply of the motor of CPU1 and saw, to cut off electric energy supply according to the order from CPU1.
Keyboard 6 is man-machine interfaces, inputs predetermined operating parameter and load the operating parameter before being stored in CPU1 to allow user.
Siren 7 also can be audio frequency and/or visible alarm, the end of the cutting operation of its report saw or fault.Such as, the beeping sound of the exportable report current operation status of audio frequency siren or voice.Visible alarm can be the colored flashing device etc. of displaying symbol or words.
Below, the operation of annular saw will be described referring to Fig. 2.
As shown in Figure 2, in step sl, the cutting parameter of the predetermined annular saw of user, such as target cut length, cutting speed etc.If next cutting is identical with cutting before, then the cutting parameter before is automatically loaded by CPU1, and does not have new cutting parameter to be transfused to.
Then, in step s 2, saw is unlocked, and start stop apparatus is activated by user, makes saw blade start to cut in workpiece.
Subsequently, in step s3, range sensor sends pulse signal to CPU1.Meanwhile, timer sum counter is started working.
Then, in step s 4 which, CPU1 process pulse signal, to determine current Cutting Length.
Then, in step s 5, related data is presented on the screen of display 4.Relevant data can comprise:
1) always distance is cut;
2) present single Cutting Length;
3) target length;
4) cutting speed; And
5) other expected datas.
Then, in step s 6, CPU1 judges whether current Cutting Length reaches target cut length.If the judged result of step S6 is "No", then operation turns back to step S4.If the judged result of step S6 is "Yes", then operation proceeds to step S7.
In the step s 7, siren 7 is activated, the audio frequency terminated with output report cutting operation and/or visual alarm.
Then, in step s 8, saw and manually turned off by user or automatically turned off by electric energy supply control unit 5 according to the order from CPU1.
According to the present invention, all related datas will be presented on display 4 in real time.
Control fitting is powered by low voltage DC power supplies, and described low voltage DC power supplies is relevant with the power supply of saw or irrelevant.
After the cut has been completed, start stop apparatus will be discharged by user, and the data of present single Cutting Length and cutting speed will be set to zero.But total cutting distance will be added up.When total cutting distance reaches a certain value, saw blade should be replaced.
Alternatively, overheated or super-high-current protected location can be connected to CPU1.The electric current of the temperature of this protected location detection-sensitive motor or supply motor, and when motor temperature higher than threshold temperature or a period of time (such as, 5 or 10 seconds) interior ER effect must higher than threshold current time, the disconnection of this protected location supplies to the electric energy of motor.Therefore, the motor overheating of saw can be prevented or burn.
Alternatively, the device for sensing and control the angle of inclination of saw blade can be connected to CPU1.This angle of inclination can be shown by display 4, and can be conditioned according to the order of CPU1.
Alternatively, the device for the depth of cut sensing and control saw blade incision workpiece can be connected to CPU1.This depth of cut can be shown by display 4, and can be conditioned according to the order of CPU1.
Alternatively, control fitting also comprises for being connected to input with outer computer or upgrading the computer connection interface of program of CPU1.
Be appreciated that other devices also can be added in this control fitting.
And cutting speed or the velocity of rotation of saw blade can be used as protective index.When saw blade to run in workpiece too hard and be difficult to the region of cutting time, the cutting speed of saw blade and/or velocity of rotation may become too low, are even zero.Now, CPU1 can supply by means of electric energy the electric energy supply that control unit 5 disconnects motor, and starts siren 7, to report this situation.
The invention discloses a kind of new method for being realized precise cutting by annular saw.
Be equipped with this annular saw of above-mentioned control fitting that terminal use can be made to understand the state of cutting process and saw more.Have display, this display can show some or all in following parameter:
Total cutting distance of a) sawing;
B) Cutting Length of present single cutting;
C) distance is cut by the target that terminal use is predetermined;
D) current cutting speed;
E) date and time; And
F) any other operating parameter.
Like this, terminal use can perform the cutting with oneself accurately predetermined target range.By the cutting speed of display with always cut distance, terminal use can understand their saw more, makes to take care of better their saw and makes saw have longer service life.
This control fitting can be attached in the annular saw of any type, such as, in miter saw and portable circular saw, and can be used for cutting any material, such as, and timber, plastics, metal, composite etc.
Although described some embodiment, these embodiments have only been given as examples, and are not used in and limit the scope of the invention.Appended claim and their equivalent replacement are intended to cover all modifications fallen in scope and spirit of the present invention, substitute and change.
