[0031] It should be noted that the features in the embodiments of the present utility model may be combined with each other without conflict.

[0032] In modern industrial production, the service life of various mechanical equipment is an important performance indicator, which directly affects the reliability of the equipment and the maintenance cost. Among them, as a common mechanical component, the self-rotation life of the handle is very important. The traditional handle life test usually requires manual operation, which is not only time-consuming and laborious, but also difficult to ensure the accuracy and repeatability of the test results. At present, some existing technical solutions adopt an automated test system to test the handle fixed with a customized fixture by controlling the motor and the motor-driven mechanical structure through a PLC control system. This method can realize the automatic test of the self-rotation life of the handle, greatly improving the test efficiency and the accuracy of the test results.

[0033] The handle self-rotation life test device in the related art has technical problems of inaccurate test results and low test efficiency.

[0034] Please refer to Figure 1 - Figure 2 , this embodiment provides a fully automatic handle self-rotation life test device 100 based on a PLC system, which can effectively improve the above-mentioned technical problems, can automatically detect the handle, ensure the accuracy of the detection results, and improve the test efficiency.

[0035] The fully automatic handle self-rotation life test device 100 based on the PLC system includes a fixture 10, a driving member 20, a movable sensor 30 and a detection module. The fixture 10 is used to clamp the handle to be tested. The driving member 20 is movably arranged relative to the fixture 10. The driving member 20 is used to drive the handle to be tested to rotate self. The movable sensor 30 is movably arranged relative to the fixture 10. The movable sensor 30 is used to detect the state of the handle to be tested. The detection module is connected to the movable sensor 30 and the driving member 20. The detection module is used to start and stop the driving member 20 according to the detection information of the movable sensor 30.

[0036] Specifically, when the handle self-rotation life test device in the prior art is in use, it is unable to record the test data of each test of the handle, and it is unable to analyze the use law and life law of the handle in detail. To solve this technical problem, the detection module of the fully automatic handle self-rotation life test device 100 based on the PLC system in this embodiment can receive each test information of the movable sensor 30 and store and record it, which helps to analyze the use law and life law of the handle in detail, makes the information obtained by the test more comprehensive, and ensures that the test results are more accurate.

[0037] Moreover, the handle self-rotation life test device in the prior art generally uses a contact sensor to detect the state of the handle. Since the handle needs to rotate continuously during the test, it will cause wear of the sensor after long-term use, thus affecting the accuracy of the test results. To solve this technical problem, the movable sensor 30 of the fully automatic handle self-rotation life test device 100 provided in this embodiment is arranged at an interval from the handle to be detected, and the movable sensor 30 and the handle to be detected are non-contact, avoiding the wear problem of the contact sensor in the prior art.

[0038] In this embodiment, the detection module sets different driving parameters, so that the driving member 20 drives the handle to be detected to be tested under different test conditions. At the same time, the detection module can automatically record each test data, including test time, test times, handle status and other information, which is convenient for later data sorting and analysis.

[0039] It should be noted that the driving member 20 includes a first driving member 21 and a second driving member 22. The first driving member 21 and the second driving member 22 are connected. The second driving member 22 is used to drive the first driving member 21 to move up and down, so that the position of the first driving member 21 corresponds to the position of the handle to be tested. The first driving member 21 is used to drive the handle to be tested to rotate self - sufficiently.

[0040] Specifically, the second driving member 22 includes a driving motor 221 and a lifting lead screw 222. One end of the driving motor 221 is connected to the lifting lead screw 222, and the other end of the lifting lead screw 222 is connected to the first driving member 21. The lifting lead screw 222 is used to drive the first driving member 21 to move up and down under the drive of the driving motor 221. Among them, the lifting lead screw 222 is arranged in the vertical direction, the driving motor 221 is arranged at the top of the lifting lead screw 222, and the first driving member 21 is arranged at the bottom of the lifting lead screw 222, so as to approach or move away from the handle to be detected in the fixture 10.

[0041] In this embodiment, the second driving member 22 is a self - rotating motor. The second driving member 22 drives the handle to be detected to rotate self - sufficiently.

[0042] It should also be noted that the movable sensor 30 includes a movable support rod 31 and a non - contact sensor 32. The non - contact sensor 32 is installed on the movable support rod 31, and the movable support rod 31 is used to drive the non - contact sensor 32 to move. Among them, the movable support rod 31 is a multi - axis connecting rod. The operator moves the multi - axis connecting rod, so that the multi - axis connecting rod drives the non - contact sensor 32 to move along the X - axis, Y - axis and Z - axis respectively, so as to move the non - contact sensor 32 to the optimal detection position and detect the state of the handle to be detected in real time.

[0043] In this embodiment, the non - contact sensor 32 is an optical fiber sensor.

[0044] In addition, the full - automatic handle self - rotation life test device 100 based on the PLC system further includes an alarm module. The alarm module is connected to the movable sensor 30. The alarm module is used to give an alarm after not receiving the alarm signal from the movable sensor 30. Among them, after the handle to be detected is damaged, the non - contact sensor 32 sends out an alarm signal, the detection module controls the driving member 20 to stop working, and the alarm module gives an alarm.

[0045] Specifically, the alarm module is an alarm horn.

[0046] Furthermore, the full - automatic handle self - rotation life test device 100 based on the PLC system further includes a test bench. The fixture 10, the driving member 20 and the movable sensor 30 are all installed on the test bench.

[0047] In this embodiment, the control module adopts a PLC controller. The control module sets the test parameters.

[0048] The full-automatic handle self-rotation life test device 100 based on the PLC system provided in this embodiment has at least the following advantages:

[0049] The detection module of the full-automatic handle self-rotation life test device 100 based on the PLC system can receive each test information of the movable sensor 30 and store and record it, which helps to analyze in detail the usage law and life law of the handle, makes the information obtained by the test more comprehensive, and ensures that the test result is more accurate.

The driving member 20 is used to drive the handle to be tested to rotate self. The movable sensor 30 is movably arranged relative to the fixture 10. The movable sensor 30 is used to detect the state of the handle to be tested. The detection module is connected to the movable sensor 30 and the driving member 20. The detection module is used to start and stop the driving member 20 according to the detection information of the movable sensor 30. When the full-automatic handle self-rotation life test device 100 based on the PLC system is in use, the handle can fixedly clamp the handle to be detected, so as to ensure the stability of the handle to be detected during the test. The driving member 20 can drive the handle to be detected to rotate self, so as to simulate the actual use state of the handle to be detected. The movable sensor 30 is movably arranged relative to the fixture 10, which can avoid the wear problem of the contact-type sensor in the prior art. At the same time, the movable sensor 30 can move relative to the handle to be detected before detection until it moves to the best detection position, so as to detect the state of the handle to be detected. After the movable sensor 30 detects that the handle to be detected is damaged, it can transmit a signal to the detection module, and the detection module controls the driving member 20 to stop moving, so as to stop the test.
