[0022] The features and advantages of the present application will become more apparent from the following description with reference to the accompanying drawings, which are not drawn to scale and in which some features can be exaggerated or minimized for the sake of clarity, in which:

[0023] Figure 1 is the appearance assembly view of the debugging device of the present application;

[0024] Figure 2 is the circuit diagram of the debugging device of the present application. DETAILED DESCRIPTION

[0025] The present application will be described in detail below with reference to the accompanying drawings by means of exemplary embodiments of the present application. It should be noted that the following detailed description of the present application is for illustrative purposes only and is not limiting to the present application.

[0026] The present application provides a debugging device and a debugging method for matching the speed of a single-tube product launch control system driver and a motor, which is designed according to the control principle of the driver. The driver control circuit mainly consists of a speed loop and a current loop. The speed loop receives an external speed given value and compares it with the speed feedback value of the servo motor. The difference is amplified by proportional integral and then sent to the input end of the current loop as a current given value. The current given value and the current feedback value are compared and amplified. The analog voltage output by the current loop is sent to the pulse width modulator to convert into a pulse signal with a corresponding amplitude. Finally, the corresponding alternating voltage is output by the power component to drive the servo motor.

[0027] As shown in Figure 1 , the debugging device for matching the speed of a launch control system driver and a motor provided by the present application comprises a socket XS, a box body, and a debugging assembly arranged on the box body. The socket XS is used to connect the driver through a cable. The driver is connected with the servo motor through an armature cable and a feedback cable.

[0028] As shown in Figure 2 , the debugging assembly comprises a speed given switch K1, a driving enable switch K2, a pulse enable switch K3, a double-pole double-throw switch K4, a speed adjustment potentiometer RP1, a first speed given voltage test interface K5, and a second speed given voltage test interface K6. These components can be arranged on a panel of the box body to facilitate the operation of the operator. Markers, such as Chinese characters, can also be marked on the corresponding positions of the panel to facilitate the identification of the purposes of the components.

[0029] The connection relationship of the debugging assembly is as follows: the input end of the speed given switch K1 is the positive electrode interface of the power supply of the debugging device, and the output end is connected with the first fixed end of the speed adjustment potentiometer RP1. The second fixed end and the sliding end of the speed adjustment potentiometer RP1 are respectively connected with the two input ends of the double-pole double-throw switch K4. The two output ends of the double-pole double-throw switch K4 are respectively connected with the input ends of the first speed given voltage test interface K5 and the second speed given voltage test interface K6. The second fixed end of the speed adjustment potentiometer RP1 is the negative electrode interface of the power supply of the debugging device.

[0030] The speed setting switch K1 controls the on / off state of the input voltage of the debugging device's power supply, cutting off the input driver's set voltage in abnormal situations. The speed adjustment potentiometer RP1 changes its internal resistance value by adjusting the position of its sliding end, thereby altering the current or voltage passing through it. This causes the voltage between the first speed set voltage test interface K5 and the second speed set voltage test interface K6 to vary between 0V and 10V. The voltage between these two interfaces is measured and displayed using a digital multimeter, allowing operators to adjust the set voltage promptly to ensure accuracy. One output terminal of the double-pole double-throw switch K4 is connected to the sliding end of the speed adjustment potentiometer RP1, and the other output terminal is connected to the second fixed terminal of RP1. The double-pole double-throw switch K4 controls the positive and negative terminals of the set voltage output, thus controlling the forward and reverse rotation of the servo motor.

[0031] The socket XS has a first pin, a second pin, a third pin, a fourth pin, and a fifth pin. The first pin is connected to the 24V voltage of the driver. The second pin is the output of the driver enable switch K2. The third pin is the output of the pulse enable switch K3. The fourth pin is the output of the first speed set voltage test interface K5. The fifth pin is the output of the second speed set voltage test interface K6. The inputs of the driver enable switch K2 and the pulse enable switch K3 are both connected to the first pin.

[0032] The XS socket connects the debugging component to the driver via the aforementioned five pins using a tooling cable. The driver's 24V voltage enters the debugging device through the first pin, and is then sent back to the driver via the driver enable switch K2 and pulse enable switch K3 to control the driver to power the servo motor. The driver enable switch K2 and pulse enable switch K3 control the driver's internal circuitry to enable the driver.

[0033] The debugging device designed in this invention simulates the corresponding control signals of the host computer, namely the given voltage in this invention, to match the speed of the driver and servo motor before the driver and servo motor are assembled into the equipment. The debugging device designed in this invention uses a tooling cable to connect to the controlled driver, controls the driver to power on and run through the driver enable switch K2 and the pulse enable switch K3, matches the speed of the servo motor by adjusting the given voltage, and controls the forward and reverse rotation of the servo motor through the double-pole double-throw switch K4.

[0034] A protective resistor R1 is connected between the speed setting switch K1 and the speed adjustment potentiometer RP1. This protects the circuitry of the testing device from damage by adjusting the current or voltage. The appropriate power rating of the protective resistor R1 needs to be selected based on the current magnitude and power consumption.

[0035] The speed regulating potentiometer RP1 selects a potentiometer with a resistance of 10KΩ, which can facilitate the use in the installation normal temperature state. The first speed given voltage test interface K5 and the second speed given voltage test interface K6 are connected with a digital multimeter, which is used for detecting the voltage value between the first speed given voltage test interface K5 and the second speed given voltage test interface K6. The debugging device further comprises a tachometer, which is used for measuring the rotating speed of the output shaft of the servo motor, and the speed matching of the driver and the servo motor is carried out based on the rotating speed of the output shaft of the servo motor.

[0036] The driver and the servo motor belong to the controlled units in the electrical system of the equipment, which are actuator devices. The driver controls the steering and rotating speed of the servo motor after corresponding response to the control signal of the host computer, so as to drive the mechanical components to move.

[0040] Step 3: According to the first rotating speed, adjust the rotating speed adjusting potentiometer of the driver to control the output voltage of the driver, so that the driver and the servo motor reach the required matching speed;

[0041] Step 4: Turn the double-pole double-throw switch K4 to the reverse position, measure the voltage between the first speed given voltage test interface K5 and the second speed given voltage test interface K6, and adjust the speed regulating potentiometer RP1 so that the measured voltage is within the given voltage range, then drive the output shaft of the servo motor to rotate reversely by the potential energy of the driver, and measure the second rotating speed of the output shaft of the servo motor;

[0042] Step 5: According to the second rotating speed, adjust the rotating speed adjusting potentiometer of the driver to control the output voltage of the driver, so that the driver and the servo motor reach the required matching speed.

[0043] Next, each step will be described in detail.

[0045] In step 2, the specific steps are as follows: first, the double-pole double-throw switch K4 is turned to the forward position, at this time, the speed of the driver and the forward servo motor is matched, then the speed adjusting potentiometer RP1 is adjusted to the minimum speed position, the speed given switch K1 is turned on, the voltage output is connected to the driver, the first voltage value between the first speed given voltage test interface K5 and the second speed given voltage test interface K6 is measured by using a multimeter, which is 0V, ensuring that the output shaft of the servo motor does not rotate after power-on, then the driving enable switch K2 and the pulse enable switch K3 are turned on, then the speed adjusting potentiometer RP1 is slowly adjusted to the required position of the given voltage, the speed of the servo motor changes smoothly, the second voltage value between the first speed given voltage test interface K5 and the second speed given voltage test interface K6 is measured by using a multimeter, which gradually approaches and reaches 10V, the output shaft of the servo motor is driven by the potential energy of the driver to rotate forward, and finally the first speed of the output shaft of the servo motor is measured by using a tachometer.

[0046] In step 3, the first speed measured at the second voltage value is 6000±30r / min, and the speed adjusting potentiometer of the driver is adjusted at this speed, so that the speed of the driver also reaches 6000±30r / min.

[0047] In step 4, the specific steps are as follows: first, the double-pole double-throw switch K4 is turned to the reverse position, at this time, the speed of the driver and the reverse servo motor is matched, then the speed adjusting potentiometer RP1 is adjusted to the minimum speed position, the speed given switch K1 is turned on, the first voltage value between the first speed given voltage test interface K5 and the second speed given voltage test interface K6 is measured by using a multimeter, which is 0V, then the driving enable switch K2 and the pulse enable switch K3 are turned on, then the speed adjusting potentiometer RP1 is slowly adjusted to the required position of the given voltage, the second voltage value between the first speed given voltage test interface K5 and the second speed given voltage test interface K6 is measured by using a multimeter, which gradually approaches and reaches 10V, the output shaft of the servo motor is driven by the potential energy of the driver to rotate reversely, and finally the second speed of the output shaft of the servo motor is measured by using a tachometer.

[0048] In step 5, the second speed measured at the second voltage value is the actual measured speed of the servo motor, and the speed adjusting potentiometer of the driver is adjusted at the speed requirement index of 6000±30r / min, so that the matching speed of the driver and the servo motor also reaches 6000±30r / min.

[0049] The speed matching of the positive rotation of the output shaft of the servo motor and the reverse rotation of the output shaft of the servo motor is carried out by adjusting the drive and the speed regulation potentiometer of the drive when the given voltage reaches 10V, so that the matching speed of the drive and the servo motor reaches 6000±30r / min. The use of the debugging device designed by the application for speed matching debugging of the drive and the servo motor meets the use requirements and ensures the reliability of the product in subsequent debugging.
