As shown in fig. 1 and fig. 2, a constant force feeding device based on processing of hard and brittle materials comprises a frame 1, a control cabinet 2 and a workbench 3, wherein the workbench 3 comprises a base 31 and an operation plate 32 positioned above the base 31, at least three vertical limiting rods 311 (three points form a plane) are uniformly arranged on the outer edge of the base 31, a plurality of limiting holes 321 matched with the limiting rods 311 are formed in the operation plate 32, a plurality of pressure sensors 4 are abutted between the operation plate 32 and the base 31, in a specific embodiment, the number of the limiting rods 311 is four and are respectively positioned on four corners of the base 31, in the actual processing process, feeding force possibly falls on the position of the operation plate 32 deviating from the center due to the placement position of a workpiece, and tilting or shaking of the operation plate 32 during cutting can be avoided through the mutually matched limiting rods 311 and the mutually matched limiting holes 321, so that the force is uniformly transmitted to the pressure sensors 4 below, and detection data is more reliable; each pressure sensor 4 is electrically connected with the control cabinet 2, the control cabinet 2 is electrically connected with a hydraulic cylinder (not shown in the figure), a hydraulic rod of the hydraulic cylinder is fixedly provided with a sliding seat 5 which is in vertical sliding connection with the frame 1, a cutting device 6 is arranged on the sliding seat 5, the pressure sensors 4 which are abutted against the operation plates 32 detect the feeding force during cutting and output signals to the control cabinet 2, and when the feeding force exceeds a threshold value, the control cabinet 2 enables the cutting device 6 to retract by a certain height through the hydraulic cylinder, and then the workpiece is continuously processed according to the original stroke; when the machining is in place, the cutting device 6 automatically withdraws; in particular, the cutting device 6 comprises a motor, preferably an ultrasonic motorized spindle, which drives the tool in rotation via the spindle and applies vibration energy at a certain hertz, and a tool, which is indirectly cut via the abrasive suspension.
As shown in fig. 2, 3 and 4, the upper surface of the operation plate 32 is provided with a storage groove 322 downwards, a mounting plate 323 is fixed in the storage groove 322, a plurality of completely through dovetail grooves 324 are formed in the side surface of the mounting plate 323, when the workpiece is mounted, a workpiece is correspondingly placed on two sides of the dovetail grooves 324, a connecting block 7 is slidably matched in the dovetail grooves 324, the connecting block 7 slides in from the side surface of the dovetail grooves 324 and moves to the workpiece, the top end of the connecting block 7 extends upwards to form a screw 71, a pressing block 8 is connected with the screw 71 in a threaded manner, and the pressing block 8 is screwed with the screw 71 and then tightly pressed by a nut so as to firmly fix the workpiece; the workpiece can be better positioned through the clamps such as the connecting block 7, the pressing block 8 and the like, and the machining precision and the machining integrity of the hard and brittle materials are better ensured during cutting.
In a specific embodiment, as shown in fig. 2, the number of the pressure sensors 4 is three, and the pressure sensors are distributed in a regular triangle, so that stability can be improved, and stress is more uniform.
In addition, as shown in fig. 1, the control cabinet 2 is further electrically connected with an alarm (not shown) and a display panel 9, the pressure sensor 4 detects the feeding force and transmits an analog signal to the display panel 9, the display panel 9 can instantly convert the feeding force into a digital signal and display the digital signal, and different threshold values can be set according to the requirement, and when the feeding force exceeds the threshold value, the alarm generates an alarm and outputs a control signal to the control cabinet 2.
As shown in fig. 1 and 2, a slide rail is horizontally fixed on the frame 1, a slide block 312 is fixed at the bottom end of the base 31, and the table 3 can move in the X-axis direction through the slide rail and the slide block 312 that are matched with each other.
The invention discloses a constant force feeding processing method based on processing of a hard and brittle material, which comprises the following steps:
(a) The magnitude of the feeding force is detected by the pressure sensor 4, an analog signal is transmitted to the display panel 9, the display panel 9 instantly converts the feeding force into a digital signal and displays the digital signal, when the feeding force exceeds a threshold value, an alarm gives an alarm and outputs a control signal to the control cabinet 2, and the control system automatically calls a rollback subroutine to enable the cutting device 6 to rollback for a certain height (specifiable), and then the workpiece is continuously processed according to the original stroke; when the tool is processed in place, the tool automatically withdraws;
(b) The sum of the weight of the work piece and the weight of the abrasive suspension on the operation plate 32 is reset to a standard value every time the work piece is retracted.
Since the workpiece material is continuously removed during processing, the abrasive suspension is also cyclically fed, so that G1 and G2 are not constant values; the feed force detection process is as follows:
the sum of the gravity G1 of the workpiece and the gravity G2 of the abrasive suspension is set as a standard value, i.e., a "null".
The feed force can be derived from f=f-G1-G2;
wherein f-feed force;
f-pressure sensor 4 detects the value.
Thus, the feeding force f can be reflected in real time by resetting the sum of the gravity G1 of the work piece and the gravity G2 of the abrasive suspension on the operation plate 32 to the standard value every time the work piece is retracted.
When the feeding force f exceeds a safety value f 0 (obtained by experiments), the normally open contact controlled by the display panel 9 is conducted, a DC24V voltage signal is output to the control cabinet 2, the control cabinet 2 further calls a rollback subprogram to control the main shaft to rollback, and the control interface circuit is shown in fig. 5.
As can be seen from fig. 5, when S1 and S4 are closed, the motor is rotating at full speed in the forward direction; when S2 and S3 are closed, the motor is reversed.
Assuming a PI port of the first singlechip 10 (model 8952) as an output port, using P1.1 and P1.0 as control positions, and when the P1 port outputs 02H, the motor rotates positively; when outputting 01H, the motor rotates reversely, when outputting 03H, the motor brakes; at output 00H, the motor coasts.
When the control cabinet 2 is required to control the steering of the motor and the rotating speed of the motor, a common relay cannot be used as a switch; because the response frequency of a general relay is low, shake is generated when the relay is closed, and the relay works unreliably in a pulse width speed regulation system; for this purpose, a transistor switch is used, the schematic diagram of which is shown in fig. 6.
As can be seen from fig. 6, when the P1 port output of the second singlechip 11 (model 8031) is 02H (p1.1=1, p1.0-0), the 4# tri-state gate of the four-bus buffer 12 (model 74LS 125) is opened to close S4, and similarly the 2# tri-state gate output is "0", the control terminal of the 1# tri-state gate is also "O" level, and the 1# tri-state gate is also opened, so that the transistor switch S1 is turned on (i.e., S1 is closed); transistor switches S1 and S4 respectively drive two Darlington power amplification tubes (one is PNP type and the other is NPN type) so as to enable the motor to rotate positively; conversely, when the P1 port outputs 01H, S2 and S3 are closed, and the motor is reversed; the reason the buffer 12 controls the connection is to ensure that the power supply is not shorted when errors occur.
The above description is only of the preferred embodiments of the present invention and is not intended to limit the present invention, but various modifications and variations can be made to the present invention by those skilled in the art. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
