The upper side of the driving sliding table 8 is fixed with a rotating motor 9, and the end part of the rotating motor 9 is connected with a drill bit 10.
The vertical distance between the adjacent in-position sensors 7 is 50 mm.
The three feeding devices in different directions are respectively an X-axis feeding device, a Y-axis feeding device and a Z-axis feeding device.
A control circuit of a configuration three-axis processing lathe comprises an MCGS touch screen, a Siemens PLC, a frequency converter, a rotating motor and a feeding motor, wherein the feeding motor comprises an X-axis feeding motor, a Y-axis feeding motor and a Z-axis feeding motor, and the rotating motor, the X-axis feeding motor, the Y-axis feeding motor and the Z-axis feeding motor are respectively connected with the frequency converter.
The communication port of the MCGS touch screen is correspondingly connected with a communication port on a Siemens PLC, ports L and N on the Siemens PLC are respectively connected with a live wire and a zero wire, the input end on the Siemens PLC is respectively connected with the zero wire through coils KM1 and KM2, the communication port 2 of the Siemens PLC is connected with a frequency converter, the output end of the frequency converter is respectively connected with a rotating motor, an X-axis feeding motor, a Y-axis feeding motor and a Z-axis feeding motor, the input end of the frequency converter connected with the rotating motor is connected with a three-phase power supply through a switch KM1, and the input end of the frequency converter connected with the feeding motor is connected with the three-phase power supply through a switch KM 2.
The feeding motor is a three-phase asynchronous motor, and the Siemens PLC is S7-200.
Example 1
The feeding motor 2 drives the transmission screw rod 3 to rotate in the fixed bearing 4 through the rigid coupling 6 under the driving of the frequency converter, and the driving sliding table 8 slides among the plurality of in-place sensors 7. In order to accurately control the feeding distance of the driving sliding table 8, real-time fluctuation data of voltage, current and frequency of the feeding motor 2 is transmitted to the Siemens PLC through a frequency converter protocol, the Siemens PLC calculates the real-time rotating speed and the feeding distance of the motor, and feeds back the actual feeding distance to the PLC to correct errors continuously through the in-place sensor 7. After the feeding is in place, the electromagnetic band-type brake 5 immediately brakes and stops the feeding of the transmission screw rod 3.
Example 2
After setting the rotation speed S of the rotating motor 9, the triple linkage feeding speed V1 (or the linkage speed V2) and the coordinates of the feeding target X, Y, Z on the MCGS type touch screen in the Beijing Kunlun general state, a user can press a start button and a stop button; the touch screen is transmitted to a Siemens S7-200PLC data V area through an RS485 communication line for storage. And S7-200PLC receives the three data of the user, the three data are converted into output voltage U and electric frequency f of the four motors after the frequency converter is started, the frequency converter starts to output according to the voltage U and the electric frequency f to control the feeding motor 2 to rotate, and single-phase current I (frequency conversion parameter R0021), rotating speed n (frequency conversion parameter R0025), torque M (frequency conversion parameter R0029) and rotating speed R31 (frequency conversion parameter R0031) parameters of each frequency conversion are fed back and read to the PLC. And the PLC calculates the feeding speed and the feeding distance of the three shafts according to the parameter feedback and corrects the feeding calculation error through a limit switch connected with a PLC input point.
Example 3
During conversion, the user sets the linkage speed V to convert the feeding speeds Vx, Vy, and Vz for each axis, taking the X axis as an example:
the starting point coordinates are x1, y1, z1, the end point coordinates are x2, y2, z2,
Vx＝V*(x2-x1)/SQRT[(x2-x1)2+(y2-y1)2+(z2-z1)2]
the PLC calculates the feeding rotating speeds Sx, Sy and Sz of the motors to be controlled by the three stations of the frequency converter 1-3 according to the formula; and the speed is transmitted to a frequency converter parameter P1080, and the frequency converter is controlled to start and is controlled by the feedback speed of the frequency converter.
Due to the limitation of the USS communication protocol, signals such as voltage (parameter r24), current (parameter r21), electric frequency (parameter r20), rotating speed (parameter r25) and the like of each variable frequency must be fed back to the PLC once according to a programming period (every 5 ms).
The rotating speed design S fed back by the frequency converter in the PLC is calculated as follows:
S＝R*(380/r24)*(I/r21)*(f/r20)
namely, the actual rotation speed is rated rotation speed (rated current/real-time current) (rated voltage/real-time voltage) (rated electrical frequency/real-time electrical frequency)
Then, the feeding distance is calculated according to the working time and the loading and unloading parameters of different structures
L＝S*t*a
t: PLC calculates motor running time
a: multiplying power of feed converted from rotating speed (related to constant pitch parameters)
Therefore, the parameter feedback is accurate, and the in-place sensor 7 added on the feed shaft corrects the calculation formula, so that the requirements of sawing machines, wood carving and the like can be met.
The above description is only for the preferred embodiment of the present invention, and is not intended to limit the present invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included within the protection scope of the present invention.
