Milling machine feeders have a significant effect on improving machine tool efficiency and reducing the labor intensity of workers.

[0003] At present, feeders with nonlinear DC power supply are usually used, and voltage-regulated thyristor trigger control is applied to make the feeder speed-regulated by voltage. It is easy to reduce the voltage, and the torque of the motor drops significantly, resulting in the feeder being unable to effectively feed the machine tool table due to too small torque, which seriously affects the normal operation of the machine tool. For example, during the process of cutting workpieces, the feed amount of the table is prone to imbalance, which affects the processing accuracy and leads to defective products; the speed regulator is connected in parallel with the same working voltage of the motor, and the speed regulator is under high voltage and high current to generate high temperature, which greatly reduces the service life and causes the feeder to fail to work normally; the forward and reverse switching switch of the feeder control panel is quickly switched, and the armature voltage of the voltage control mode cannot be turned off instantly, resulting in a surge in commutation current, causing a large voltage drop on the machine tool control transformer, affecting other machine tool control electrical appliances that share the same transformer power supply.

By replacing voltage regulation with signal regulation, the service life of the machine is effectively extended and the feeder failure rate is reduced. Through the signal-driven delay mode, the armature 0 voltage state commutation start operation is effectively improved, and the commutation impact current is excessive, and the instantaneous voltage drop of the machine tool transformer is effectively improved. The undervoltage fault of the control system sharing the same machine tool control transformer power supply due to the instantaneous voltage drop is eliminated, and the feeder control stability is improved.

[0072] In one embodiment, Figures 4 to 6 As shown, the first power supply regulating unit includes a transformer T1. The second power supply regulating unit includes: a third diode D3, a fifth diode D5, a fourteenth diode D14, a fifteenth diode D15, a tenth capacitor C10, a varistor ZNR1 and a first capacitor C1. The third power supply regulating unit includes a fourth diode D4, a tenth diode D10, a thirteenth resistor R13, a first voltage regulator diode ZD1, an eleventh diode D11, a fourteenth capacitor C14, a seventh capacitor C7, and an eighteenth diode D18.

[0073] The detection control module includes a processing chip U2, an eighth capacitor C8, a twelfth capacitor C12, a fourth resistor R4, a fifth capacitor C5, a sixth resistor R6, a sixteenth resistor R16, an eleventh resistor R11, a sixth diode D6, and a seventeenth resistor R17.

[0074] The signal acquisition module includes a fifth resistor R5, a first diode D1, a fifteenth resistor R15, a fourteenth resistor R14, a twelfth resistor R12, a twenty-first resistor R21, a sixteenth diode D16, a twenty-first resistor R21, a twelfth resistor R12, a seventh resistor R7, an eighth resistor R8, a ninth resistor R9 and a tenth resistor R10.

[0075] The driving module includes a sixteenth resistor R16, a first switch tube Q1, a seventh capacitor C7, an eleventh capacitor C11, a sixth capacitor C6, a twelfth resistor R12, a twelfth diode D12, a thirteenth diode D13, a second switch tube Q2, a third switch tube Q3, a nineteenth resistor R19, a twentieth resistor R20, an inductor L1, an eighth diode D8, a ninth diode D9 and a seventh diode D7. The motor module includes a first interface P1 and a second interface P2. The first interface P1 is used to plug in the motor stator, and the second interface P2 is used to plug in the motor armature. The control and regulation module may include a first switch K1, a second switch K2 and a third interface P9. The third interface P9 is used to plug in the speed regulator.

[0076] For example, when the user turns on the power switch, the first power supply regulating unit converts the AC220V of the external power supply into AC110V through the transformer T1. The second power supply regulating unit adjusts the AC110V AC power to DC110V through the third diode D3, the fifth diode D5, the fourteenth diode D14, the fifteenth diode D15, the tenth capacitor C10, the varistor ZNR1 and the first capacitor C1 for rectification, filtering and voltage stabilization. After rectification, the DC110V voltage signal is supplied to the motor stator for operation, the drive module for operation, and the third power supply regulating unit for transmission. The DC110V voltage signal is converted to DC and stabilized by the fourth diode D4, the tenth diode D10, the second resistor R2, the first voltage regulator diode ZD1, the eleventh diode D11, and the fourteenth capacitor C14 of the third power supply regulating unit to output a DC22V voltage signal, and the DC22V voltage signal is transmitted to the detection control module and the signal acquisition module for power supply, so that each circuit module is in a standby state after receiving the power supply signal.

[0077] When the user operates the first switch K1 of the control and adjustment module to work, the operation command signal is collected by the signal acquisition module and transmitted to the detection control module. The detection control module receives the operation command signal. When the speed regulator of the control and adjustment module sends a speed regulation signal, the speed regulation signal is transmitted to the processing chip U2 after passing through the seventeenth resistor R17, the sixth diode D6, the eighth capacitor C8, and the fifth resistor R5. The processing chip U2 processes the received signal. When the detection control module evaluates that the signal is correct, U2 outputs a control signal to the drive module.

[0078] The first switch tube Q1 of the driving module is turned on after receiving the control signal, and drives the inductor L1 to start oscillating. The inductor L1 generates a driving pulse voltage signal. It should be noted that the primary-to-secondary turns ratio of the driving coil can be 1 or 0, depending on the power supply voltage to induce the secondary. Then, after the secondary of the driving coil obtains the pulse voltage signal, it drives the third switch tube Q3 and the second switch tube Q2 through the thirteenth diode D13, the fourteenth diode D14, the twentieth resistor R20, and the nineteenth resistor R19. At this time, the voltage of the secondary of the driving inductor L1 changes with the pulse width ratio of the third switch tube Q3. The secondary pulse of the driving coil further linearly adjusts the voltage of the output voltage ratio of the first switch tube Q1 and the second switch tube Q2. After that, it is rectified by the seventh diode D7, the eighth diode D8, and the ninth diode D9 and sent to the motor armature for speed regulation, so that the motor module can operate. The real-time operation signal after the motor runs is fed back to the signal acquisition module through the sixteenth diode D16 and the twenty-first resistor R21. The operation signal is transmitted to the processing chip U2 of the detection control module through the signal acquisition module, and then the processing chip U2 of the detection control module is adjusted in real time according to the operating status of the motor.

[0079] Exemplarily, the processing chip U2 can determine the speed and torque of the feeder according to the voltage of the motor operation. When the user wants to reverse the motor, the armature current of the motor is too large. In order to avoid large current sparking and lowering the device voltage, the detection control module controls the time of capacitor charging and discharging, and the pulse width ratio of the first switch tube Q1 is used to adjust the on-off delay of the third switch tube Q3 and the second switch tube Q2, thereby controlling the conversion current of the motor armature to make the device more stable, and the linear speed regulation does not produce excessive current sparks. The voltage at the motor armature is 0V, so that the feeder is accelerated; when the third switch tube Q3 is fully opened linearly, the voltage generated by the driving inductor coil is the largest, and the voltage generated by the driving inductor coil induction pulse is the largest, then the first switch tube Q1 and the second switch tube Q2 output the highest voltage to provide the motor for acceleration. It should be noted that when the power supply is lower than 98V, the acceleration function is stopped because the power supply voltage is lower than the set value of the processing chip U2, and the speed can only be adjusted by the speed regulator of the control and regulation module to ensure that the feeder can continue to be used in a low-voltage environment.

[0080] In the above embodiment, the feeder motor speed is adjusted by adjusting the pulse duty cycle to achieve the feed amount adjustment of the milling machine table; the PWM pulse converter is adjusted by the temperature compensation output level sensed inside the motor to make the motor system feedback working state run smoothly, and the motor continuously adjusts the output pulse width modulation control mode under the effect of preventing current mutation due to the inductance to improve the acceleration torque in the high and low speed dynamic performance of the motor, thereby automatically adjusting the high and low speed feed running torque of the milling machine feeder and improving the smooth control of the milling machine table feed amount; a voltage comparator is used to compare the speed adjustment potentiometer and the fast forward button voltage, and the speed regulator and the fast forward switch are reasonably distributed. For example, the voltage allocated to the speed regulator is 90% of the output voltage, and the feeder is 90% of the full speed feed speed. The voltage assigned to the fast forward button is 100% of the output voltage, and the feeder feed speed is 100% of the maximum speed, so that the maximum speed of the feeder speed regulator is lower than the maximum speed of pressing the fast forward button switch. The milling machine table needs to move the feeder quickly. When the speed regulator is in the highest speed state, by pressing the acceleration switch, the milling machine table obtains the fastest feed speed. When the acceleration switch is released, the table restores the corresponding feed speed of the speed regulator, effectively reducing the number of speed regulator adjustments and increasing the service life of the speed regulator; the feeder rapid reversing generates several times the working current, and through the signal drive delay mode, the armature 0 voltage state time is extended to achieve reversing start-up at a lower speed, effectively improving the instantaneous voltage drop of the machine tool control transformer due to excessive reversing current, and effectively improving the operation stability of the control system that shares the same transformer output power supply. The pulse width modulation control method is adopted to completely replace the milling machine feeder voltage trigger pulse transformer control switch tube adjustment method.
