[0019] like Figure 1 As shown, this utility model discloses a machine tool testing device, including a connector for connecting to a machine tool and a testing circuit connected to the connector. The connector has at least 16 pins, namely pins I1, I2, I3, ..., I16, wherein the fifth pin, the ninth pin, and the eighth pin are electrically connected. The detection circuit includes a first digital voltmeter PV1 connected between the first and second pins, a second digital voltmeter PV2 connected between the second and third pins, a third digital voltmeter PV3 connected between the first and third pins, a first detection button SB1 connected between the fifth and fifteenth pins, a second detection button SB2 connected between the fifth and sixteenth pins, a third detection button SB3 connected between the fifth and seventh pins, a fourth detection button SB4 connected between the fifth and sixth pins, a first indicator light L1 connected between the fourth and tenth pins, a second indicator light L2 connected between the fourth and eleventh pins, a third indicator light L3 connected between the fourth and twelfth pins, a fourth indicator light L4 connected between the fourth and thirteenth pins, and a fifth indicator light L5 connected between the fourth and fourteenth pins.

[0020] Using the aforementioned machine tool testing device, during testing, the connector is directly plugged into the machine tool's interface, which is the interface connected to the multi-bar automatic feeder. After the testing device's connector and the machine tool interface are connected, their connection relationship is as follows: Figure 1 As shown. The detection principle is as follows:

[0021] Power supply section detection principle:

[0022] Turn on the machine tool power. The first digital display voltmeter PV1, the second digital display voltmeter PV2, and the third digital display voltmeter PV3 will display the three-phase voltage values ​​of the power supply (R, S, T) respectively. If the voltage values ​​displayed by the three digital display voltmeters are not the target voltage, turn off the machine tool power and check the wiring. If the voltage values ​​displayed by the three digital display voltmeters are not the same, it means that a phase is missing, and the wiring also needs to be checked.

[0023] The input terminal, i.e., the signal checking principle of the automatic bar feeder for machine tools, is as follows:

[0024] The first indicator light L1, the second indicator light L2, the third indicator light L3, the fourth indicator light L4, and the fifth indicator light L5 represent five signals: machine tool emergency stop, chuck open, material change allowed, manual mode, and thrust pause, respectively.

[0025] 1. Machine tool side action - chuck opening, second indicator light L2 illuminates; machine tool side action - chuck closing, second indicator light L2 goes out. This indicates a normal signal and correct wiring. Otherwise, it's abnormal; check the PLC program and wiring.

[0026] 2. Machine tool side action - Execute M90 ​​code, the third indicator light L3 will light up. Press the third detection button SB3, and the third indicator light L3 will turn off, indicating a normal signal and correct wiring. Otherwise, it is abnormal, check the PLC program and wiring.

[0027] 3. Machine tool side action - switch to manual mode, the fourth indicator light L4 will light up; machine tool side action - switch to non-manual mode, the fourth indicator light L4 will turn off, indicating a normal signal and correct wiring. Otherwise, it is abnormal, check the PLC program and wiring.

[0028] 4. Machine tool side action - executing M88 code, the fifth indicator light L5 will light up; machine tool side action - executing M89 code, the fifth indicator light L5 will turn off. This indicates a normal signal and correct wiring. Otherwise, it is abnormal; check the PLC program and wiring.

[0029] 5. Machine-side action - Press the emergency stop button, the first indicator light L1 will light up; Machine-side action - Reset the emergency stop button, the first indicator light L1 will turn off, indicating a normal signal and correct wiring. Otherwise, it is abnormal, check the socket wiring.

[0030] The principle of signal checking at the output end of the multi-bar automatic feeder to the machine tool:

[0031] The detection device has four buttons: the first detection button SB1, the second detection button SB2, the third detection button SB3, and the fourth detection button SB4, which represent four signals: material shortage, material machine alarm, material change completed, and material machine automatic mode, respectively.

[0032] 1. Material shortage signal check

[0033] Testing device side operation: Briefly press the first testing button SB1 and check that the machine tool's BDT indicator light remains constantly on. Press the first testing button SB1 again; if the machine tool's BDT indicator light goes out, the signal is normal and the wiring is correct. Otherwise, it is abnormal, and the PLC program and wiring should be checked.

[0034] 2. Check the alarm signal of the feeder.

[0035] Detection device operation: Press and hold the second detection button SB2. The machine tool CNC display will show a "Material Machine Abnormal Alarm" screen. The machine tool cannot reset the alarm at this time. Release the second detection button SB2 and then press the reset button on the machine tool CNC display. The "Material Machine Abnormal Alarm" will be cleared, indicating a normal signal and correct wiring. Otherwise, if an abnormality occurs, check the PLC program and wiring.

[0036] 3. Check the material change completion signal.

[0037] Machine tool side action: Executing code M90 ​​will illuminate the third indicator light L3. Pressing the second detection button SB2 will extinguish the third indicator light L3, indicating a normal signal and correct wiring. Otherwise, an abnormality exists, and the PLC program and wiring should be checked.

[0038] 4. Automatic signal check of the feeder

[0039] Detection device operation: Press and hold the fourth detection button SB4. The machine tool CNC display will show a "Material feeder in non-automatic mode alarm" message. The machine tool cannot reset this alarm at this time. Release the fourth detection button SB4 and then press the reset button on the machine tool CNC display. The "Material feeder in non-automatic mode alarm" will be cleared, indicating a normal signal and correct wiring. Otherwise, if an abnormality occurs, check the PLC program and wiring.

[0040] Using the above method, all critical signal interfaces of the machine tool can be tested, ensuring that the machine tool is compatible with all types of multi-bar automatic feeders from the factory. If only testing of all critical signal interfaces of the machine tool is required, only 16 pins are needed on the connector.

[0041] To facilitate operation and enable protection of the detection circuit, the detection device also includes an insulating junction box. The first digital display voltmeter, the second digital display voltmeter, the third digital display voltmeter, the first detection button, the second detection button, the third detection button, the fourth detection button, the first indicator light, the second indicator light, the third indicator light, the fourth indicator light, and the fifth indicator light are all located on the insulating junction box.

[0042] To facilitate observation during the testing process, the first, second, and third digital voltmeters are arranged sequentially and in the same row; the first, second, third, and fourth test buttons are arranged sequentially and in the same row; and the first, second, third, fourth, and fifth indicator lights are arranged sequentially.

[0043] For ease of operation, information prompts are provided on the insulated junction box corresponding to the first, second, third, and fourth detection buttons, as well as the first, second, third, fourth, and fifth indicator lights. For example, the prompt message "Chuck Open Indicator" can be set on the first indicator light L1, "Chuck Open Indicator" on the second indicator light L2, "M90 Material Change Indicator" on the third indicator light L3, "Machine Tool Manual Indicator" on the fourth indicator light L4, and "Machine Tool Emergency Stop Indicator" on the fifth indicator light L5.

[0044] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
