Specific embodiment
Below in conjunction with drawings and examples, the present invention is described in detail.
As depicted in figs. 1 and 2, a kind of constant force feeding device based on hard brittle material processing, including rack 1,2 and of control cabinet
Workbench 3, workbench 3 include pedestal 31 and the operation panel 32 above pedestal 31, are uniformly arranged at outer rim on pedestal 31
Have at least three vertical 3 points of gag lever post 311(compositions, one plane), it offers on operation panel 32 several with 311 phase of gag lever post
The limit hole 321 mutually cooperated has abutted several pressure sensors 4, in a specific embodiment between operation panel 32 and pedestal 31
In, 311 quantity of gag lever post is four, is located on four angles of pedestal 31, in the actual processing process, because workpiece is put
Position centripetal force may fall in operation panel 32 and deviate at center, by mutually matched gag lever post 311 and limit hole 321,
Tilting or shaking can occur in cutting to avoid operation panel 32, be transferred to power uniformly on the pressure sensor 4 of lower section, make
Detection data is relatively reliable；Each pressure sensor 4 is electrically connected with control cabinet 2, and control cabinet 2 is electrically connected with hydraulic cylinder (in figure
Do not show), the hydraulic stem of hydraulic cylinder is fixed with the slide 5 for sliding connection vertically with rack 1, cutting apparatus 6 is installed on slide 5,
The size of centripetal force and control cabinet 2 is outputed signal to when the pressure sensor 4 abutted with operation panel 32 detects cutting, works as feeding
When power is more than threshold value, control cabinet 2 makes 6 rollback certain altitude of cutting apparatus by hydraulic cylinder, then proceedes to process by former stroke
Workpiece；When processing in place, cutting apparatus 6 can also be retracted automatically；Specifically, cutting apparatus 6 includes motor, main shaft and knife
Tool, wherein main shaft is preferably ultrasonic wave electro spindle, and motor is rotated by main shaft drives cutter, and applies the vibration of certain hertz
Energy realizes cutting by abrasive suspension indirectly.
As shown in Figure 2, Figure 3 and Figure 4,32 upper surface of operation panel offers downwards article putting groove 322, fixes in article putting groove 322
Have a mounting plate 323, the side of mounting plate 323 offer it is several completely through dovetail groove 324, workpiece during installation, in dovetail
The two sides of slot 324 are corresponding to place a workpiece, is sliding combined with link block 7 in dovetail groove 324, by link block 7 from dovetail groove 324
Side slides into, and is moved at workpiece, and the top of link block 7 upwardly extends to form screw rod 71, and screw rod 71 is threaded with briquetting
8, it is tightened after briquetting 8 is threadedly coupled with screw rod 71 and by nut, workpiece is firmly pushed down into fixation；Pass through link block 7, pressure
The fixtures such as block 8 can preferably position workpiece, and when cutting better ensures that the machining accuracy and processing integrality of hard brittle material.
In a specific embodiment, as shown in Fig. 2, the quantity of pressure sensor 4 is three, and in equilateral triangle point
Stability can be improved in cloth, makes to be more uniformly stressed.
In addition, as shown in Figure 1, control cabinet 2 is also electrically connected with alarm (not shown) and display panel 9, pressure sensing
Device 4 detects the size of centripetal force, and transmits analog signal to display panel 9, it can be converted into counting by display panel 9 immediately
Word signal is simultaneously shown, also can be set as needed different threshold values, and when centripetal force is more than threshold value, alarm is warned
It reports and exports control signal to control cabinet 2.
As depicted in figs. 1 and 2, sliding rail is horizontally fixed in rack 1, the bottom end of pedestal 31 is fixed with sliding block 312, passes through phase
The sliding rail and sliding block 312 mutually cooperated may be implemented workbench 3 and move in the X-axis direction.
A kind of constant force feeding processing method based on hard brittle material processing of the present invention, comprising the following steps:
(a) size of centripetal force is detected by pressure sensor 4, transmitting analog signal to display panel 9, display panel 9 by its
Immediately be converted into digital signal and show, when centripetal force be more than threshold value when, alarm occur alarm and export control signal to
Control cabinet 2, control system call back out routine to make 6 rollback certain altitude (may specify) of cutting apparatus automatically, continue later by
Former stroke workpieces processing；When processing in place, tool can also be retracted automatically；
(b) it retracts every time, the sum of the gravity of workpiece and abrasive suspension gravity on operation panel 32 is set to standard value again.
Since in process, workpiece material is constantly removed, abrasive suspension is also circulation supply, therefore G1 and G2
It is not steady state value；Centripetal force detection process is as follows:
The sum of the gravity G1 of workpiece and abrasive suspension gravity G2 are set to standard value, i.e., " zero-bit ".
Centripetal force can be obtained by following formula: f=F-G1-G2；
In formula, f-centripetal force；
4 detected value of F-pressure sensor.
In this way, every rollback, i.e., again set the sum of gravity G1 of workpiece on operation panel 32 and abrasive suspension gravity G2
For standard value, it can reflect the size of centripetal force f in real time.
When centripetal force f is more than safety value f 0 (by testing), the normally opened contact conducting that display panel 9 controls, output
DC24V voltage signal retracts to control cabinet 2, control cabinet 2 and then calling back out routine control main shaft, and control interface is such as
Shown in Fig. 5.
As shown in Figure 5, when S1 and S4 is closed, motor rotates forward at full speed；When S2 and S3 is closed, motor reversion.
Assuming that first singlechip 10(model 8952) PI mouth be delivery outlet, make control bit with P1.1 and P1.0, work as P1
When mouth output 02H, motor is rotated forward；When exporting 01H, motor reversion: when output 03H, motor brake；When exporting 00H, electricity
Motivation slides.
It, cannot be with general when control cabinet 2 had not only required the steering of control motor, but also required the revolving speed of control motor
Relay is when switch；Because general relay response frequency is lower, shake, the work in pwm speed control system are generated when closure
It is unreliable to make；It is changed to transistor switch thus, schematic diagram is as indicated with 6.
It will be appreciated from fig. 6 that working as second singlechip 11(model 8031) the output of P1 mouth for 02H (P1.1=1, P1.0-0)
When, four bus buffer 12(model 74LS125) 4# tri-state gate open, be closed S4, similarly 2# tri-state gate output is
" 0 ", making the control terminal of 1# tri-state gate is also " O " level, opens 1# tri-state gate also, so (i.e. S1 is connected in transistor switch S1
Closure)；Transistor switch S1 and S4 respectively drive two Darlington power tubes (one is positive-negative-positive, another is NPN type), make
Motor rotates forward；Conversely, as P1 mouthfuls of output 01H, S2 and S3 closure, motor reversion；The reason of control connection of buffer 12
It is to guarantee not make power supply short circuit when error code.
The foregoing is only a preferred embodiment of the present invention, is not intended to restrict the invention, for the skill of this field
For art personnel, the invention may be variously modified and varied.All within the spirits and principles of the present invention, made any to repair
Change, equivalent replacement, improvement etc., should all be included in the protection scope of the present invention.
