[0056] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0057] like Figure 1 and Figure 2As shown, a first embodiment of the present invention provides a detection method for a rotary worktable, and the detection method for a rotary worktable includes: making the rotary worktable 30 to be detected be in a power-on state; performing a detection operation on the rotary worktable 30 to be detected, and when the result of the detection operation is that there is no abnormality, issuing a qualified signal; when the result of the detection operation is that there is an abnormality, issuing an alarm signal; wherein the detection operation includes: obtaining the radial clearance of the motor bearing of the rotary worktable 30 to be detected, and determining whether the result of the detection operation is an abnormal state or a non-abnormal state according to the size of the radial clearance; and / or, obtaining the running sound of the motor of the rotary worktable 30 to be detected, and determining whether the result of the detection operation is an abnormal state or a non-abnormal state according to the running sound of the motor.

[0058] By using the detection method of the rotary table provided in the first embodiment of the present invention, it is possible to timely detect abnormal radial clearance of the motor bearing and abnormal operating sound of the motor, which is crucial for predicting and preventing equipment failures. Through regular or continuous detection, maintenance or replacement of parts can be carried out in advance before serious problems occur in the equipment, avoiding production interruptions and high maintenance costs caused by sudden failures, thereby improving the reliability and stability of the equipment. By detecting and warning of equipment abnormalities in advance, sudden failures during high-load or high-speed operation can be avoided, reducing the safety risks faced by operators and improving the overall safety of the production environment. Therefore, the detection method of the rotary table provided in this embodiment can solve the technical problem in the prior art that the rotary table is prone to abnormal noise during actual work.

[0059] It should be noted that, when the alarm signal is issued, the staff will inspect the rotary table 30 to be inspected, and re-perform the inspection operation after the inspection. When the qualified signal is issued, the rotary table 30 to be inspected will be used for actual production work. When the inspection operation generates multiple inspection results, the qualified signal will be issued only when the multiple inspection results are all in a normal state.

[0060] Specifically, the radial clearance of the motor bearing of the rotary table 30 to be detected is obtained, and the method for determining whether the result of the detection operation is in an abnormal state or in a non-abnormal state according to the size of the radial clearance includes: determining whether the result of the detection operation is in an abnormal state or in a non-abnormal state through a clearance judgment process; the clearance judgment process includes: obtaining the radial clearance δ of the motor bearing, δ=(Dd) / 2, to obtain a clearance detection value; wherein D is the inner diameter of the outer ring of the motor bearing, and d is the outer diameter of the inner ring of the motor bearing; when the clearance detection value is not within the preset clearance range, determining that the result of the detection operation is in an abnormal state; when the clearance detection value is within the preset clearance range, determining that the result of the detection operation is in a non-abnormal state. With such a setting, the accurate measurement of the radial clearance can help the operator or maintenance personnel quickly locate problems such as improper bearing installation, so as to take corrective measures at an early stage, avoid further mechanical damage, and improve the stability and life of the equipment. By setting the preset range of the radial clearance, the judgment of the bearing state is transformed from qualitative to quantitative, and a standardized fault detection process is realized. This not only reduces misdiagnosis or missed diagnosis caused by differences in human judgment, but also improves the repeatability and reliability of the detection results.

[0061] It should be noted that the preset clearance range is the range of the radial clearance of the motor bearing of the rotary table in normal working condition, and "the rotary table in normal working condition" means that the rotary table will not make abnormal noise during operation.

[0062] It should be noted that the inner diameter of the outer ring of the motor bearing refers to the maximum inner diameter of the outer ring, and the outer diameter of the inner ring of the motor bearing refers to the maximum outer diameter of the inner ring.

[0063] Specifically, the method of obtaining the running sound of the motor of the rotary table 30 to be detected and determining whether the result of the detection operation is an abnormal state or a non-abnormal state according to the running sound of the motor includes: determining the result of the detection operation as an abnormal state or a non-abnormal state through a sound detection process; the sound detection process includes: obtaining the running noise value of the motor; comparing the running noise value with the preset noise value; when the running noise value is greater than the preset noise value, determining that the result of the detection operation is an abnormal state; when the running noise value is less than or equal to the preset noise value, re-entering the sound detection process. With such a setting, by real-time monitoring of the motor running noise value, wear, imbalance or other potential problems inside the motor can be discovered in time. Since abnormal sound is a common early sign of equipment failure, this method can effectively warn, avoid the equipment from continuing to operate under unknown failures, and reduce sudden downtime and maintenance costs. When the running noise value is less than or equal to the preset noise value, the detection process will be restarted, realizing continuous monitoring and self-verification of the motor state, and ensuring the stability of the equipment during long-term operation.

[0064] It should be noted that the preset noise value is the operating noise value of the motor of the rotary table in normal working state. The operating noise value of the motor refers to the current operating noise value of the motor or the maximum operating noise value of the motor within a preset time period.

[0065] Specifically, the method of obtaining the operating sound of the motor of the rotary worktable 30 to be detected and determining whether the result of the detection operation is an abnormal state or no abnormal state according to the operating sound of the motor includes: determining the result of the detection operation as an abnormal state or no abnormal state through a sound detection process; the sound detection process includes: obtaining the operating sound waveform of the motor; comparing the operating sound waveform with the operating standard waveform; when the operating sound waveform does not conform to the operating standard waveform, determining that the result of the detection operation is an abnormal state; when the operating sound waveform conforms to the operating standard waveform, re-entering the sound detection process. With such a setting, by comparing the motor operating sound waveform with the standard waveform, it is possible to accurately identify abnormal sounds in the operation of the motor, including subtle frequency changes or waveform distortions in the noise. This method can more accurately identify early signs of wear or failure of the motor.

[0066] It should be noted that the standard operating waveform is the operating sound waveform of the motor of the rotary table in a normal working state. The operating sound waveform of the motor refers to the operating sound waveform of the motor within a preset time period.

[0067] Specifically, the method of obtaining the operating sound condition of the motor of the rotary worktable 30 to be detected and determining whether the result of the detection operation is an abnormal state or a non-abnormal state according to the operating sound condition of the motor also includes: repeating the sound detection process n times, and when the operating noise value of each of the n sound detection processes is less than or equal to the preset noise value, determining that the result of the detection operation is a non-abnormal state; when the operating noise value of any one of the n sound detection processes is greater than the preset noise value, determining that the result of the detection operation is an abnormal state. In this way, repeating the sound detection process n times and making a comprehensive judgment based on the n results can improve the accuracy and reliability of fault judgment. This method reduces the accidental errors that may be caused by a single detection and ensures the robustness of equipment status assessment.

[0068] Specifically, the method of obtaining the operating sound condition of the motor of the rotary worktable 30 to be detected and determining whether the result of the detection operation is an abnormal state or a non-abnormal state according to the operating sound condition of the motor also includes: repeating the sound detection process n times, and when the operating sound waveform of each of the n sound detection processes is consistent with the operating standard waveform, determining that the result of the detection operation is a non-abnormal state; when the operating sound waveform of any one of the n sound detection processes does not conform to the operating standard waveform, determining that the result of the detection operation is an abnormal state. In this way, repeating the sound detection process n times and making a comprehensive judgment based on the n results can improve the accuracy and reliability of fault judgment. This method reduces the accidental errors that may be caused by a single detection and ensures the robustness of equipment status assessment.

[0069] Specifically, n≥3.

[0070] In this embodiment, after determining that the result of the detection operation is an abnormal state, the detection method of the rotary table also includes: acquiring an internal structure image of the motor to obtain an actual image of the motor; comparing the actual image of the motor with the standard image of the motor, and determining the position of the structural abnormality of the motor according to the comparison result; wherein the standard image of the motor refers to the internal structure image corresponding to the motor in a normal state. With such a setting, by acquiring the internal structure image of the motor and comparing it with the standard image, structural abnormalities inside the motor, such as wear, cracks, or component misalignment, can be accurately identified, thereby accurately locating the fault and reducing the troubleshooting time. Visualizing the internal structure of the motor helps maintenance personnel to intuitively understand the motor status, avoids misdiagnosis that may be caused by relying on experience or indirect signal judgment, and improves the accuracy of diagnosis.

[0071] It should be noted that the actual image of the motor is the internal structure image of the motor of the rotary worktable 30 to be inspected in the current state, and the standard image of the motor is the internal structure image of the motor of the rotary worktable that can work normally in the current state. The current state can be an operating state in which the drive part of the motor is in a driving state or a non-operating state in which the drive part of the motor is in a stationary state.

[0072] Specifically, the method for performing a detection operation on the rotary table 30 to be detected includes: obtaining the voltage of the motor of the rotary table 30 to be detected; when the voltage of the motor is greater than or equal to the preset motor voltage value, performing a detection operation on the rotary table 30 to be detected; when the voltage of the motor is less than the preset motor voltage value, issuing an alarm signal. With such a structural setting, by detecting whether the motor voltage reaches the preset value, it is ensured that the detection can be performed at a safe voltage, avoiding detection abnormalities caused by insufficient voltage, thereby ensuring the stability and safety of the equipment.

[0073] Specifically, the detection operation also includes: obtaining the operating condition of the encoder of the rotary table 30 to be detected, wherein the operating condition of the encoder includes the resolution, accuracy and response time of the encoder; judging whether the operating condition of the encoder meets the preset qualified operating condition; when the operating condition of the encoder meets the preset qualified operating condition, determining that the result of the detection operation is a non-abnormal state; when the operating condition of the encoder does not meet the preset qualified operating condition, determining that the result of the detection operation is an abnormal state; wherein the operating condition of the encoder meets the preset qualified operating condition, including: the resolution of the encoder is within the preset qualified resolution range, the accuracy of the encoder is within the preset qualified accuracy range, and the response time of the encoder is within the preset qualified response time range. With such a setting, the encoder is a key component for realizing high-precision rotation of the rotary table. By detecting its resolution, accuracy and response time, it can be ensured that the equipment obtains accurate position information during operation, thereby improving the processing accuracy. Ensuring that the operation of the encoder meets the preset standard reduces equipment abnormalities caused by encoder failure, improves the operating reliability of the equipment, and ensures the continuity and quality consistency of the production process.

[0074] In this embodiment, the radial clearance of the motor bearing of the rotary table 30 to be detected is obtained, and the result of the detection operation is determined to be an abnormal state or no abnormal state according to the size of the radial clearance as the first detection step; the operating sound of the motor of the rotary table 30 to be detected is obtained, and the result of the detection operation is determined to be an abnormal state or no abnormal state according to the operating sound of the motor as the second detection step; the operating condition of the encoder is obtained, and the result of the detection operation is determined to be an abnormal state or no abnormal state according to whether the operating condition of the encoder meets the preset qualified operating condition as the third detection step. The method for performing a detection operation on the rotary table 30 to be detected includes: setting the detection interval duration; after completing the first detection step, performing the second detection step after the interval detection interval duration; after completing the second detection step, performing the third detection step after the interval detection interval duration. With such a setting, by setting the detection interval duration, multiple detection steps are carried out in an orderly manner, forming a systematic troubleshooting process, and ensuring a comprehensive inspection of the rotary table. Based on the test results, the maintenance plan can be adjusted intelligently, and the inspection and maintenance of equipment can be arranged reasonably to avoid excessive or insufficient maintenance and optimize the maintenance cost.

[0075] like Figure 2 As shown, Figure 2The method of obtaining the running sound of the motor of the rotary table 30 to be detected in the detection method of the rotary table in this scheme, and determining whether the result of the detection operation is abnormal or not according to the running sound of the motor, is illustrated in FIG. The control chip initialization is the first step of the detection, which is mainly to initialize the control chip to ensure that it is ready for subsequent detection operations. The chip reads the collected data. The chip is a low-power, high-speed processor that can process 12 channels of data at the same time and has a memory storage function. Initialization may include steps such as setting the working mode, calibrating the sensor, and clearing historical data. Starting the timing T1 refers to setting a timer, which is used to control the time interval in the detection process, that is, the detection interval duration, to ensure the continuity of the detection operation. Transmitting ultrasonic waves is one of the key steps in the detection process. The structural state of the motor of the rotary table is detected by transmitting ultrasonic waves, such as detecting the vibration of the motor bearing or other components. Ultrasonic detection technology can provide non-contact internal structure information, which is very effective for early detection of potential mechanical failures. Receiving data refers to receiving the reflected ultrasonic signal after transmitting the ultrasonic wave, and judging whether there is an abnormality inside the motor of the rotary table through data analysis. This step may involve signal processing, filtering and analysis to accurately obtain data reflecting the status of the workbench. Judging whether the "wave sound is returned" is used to detect whether the reflected wave is successfully received. If the ultrasonic signal is not received (no), it returns to the "receive data" step and continues to wait for the signal to return; if the signal is successfully returned (yes), the process continues to the next step. When the set timing time is over, it means that this round of detection operation has been completed, and enter the next step for data processing and result judgment. The completion of data reading indicates that all necessary data has been collected and is ready to enter the result analysis and judgment stage. After the detection operation is completed, a corresponding signal is issued according to the test result, such as a qualified signal or an alarm signal.

[0076] like Figure 3 and Figure 4As shown, the second embodiment of the present invention provides a detection device for a rotary table, and the detection device for the rotary table is used to execute the detection method for the rotary table provided in the first embodiment, and the detection device for the rotary table includes a power connection unit and a detection unit. The power connection unit is used to make the rotary table 30 to be detected in a power-on state. The detection unit is used to perform a detection operation on the rotary table 30 to be detected, and send out a qualified signal when the result of the detection operation is that there is no abnormal state; and send out an alarm signal when the result of the detection operation is that there is an abnormal state; wherein the detection operation includes: obtaining the radial clearance of the motor bearing of the rotary table 30 to be detected, and determining whether the result of the detection operation is an abnormal state or a non-abnormal state according to the size of the radial clearance; and / or, obtaining the running sound of the motor of the rotary table 30 to be detected, and determining whether the result of the detection operation is an abnormal state or a non-abnormal state according to the running sound of the motor.

[0077] The detection device for the rotary table provided in the second embodiment of the present invention can promptly detect abnormal radial clearance of the motor bearing and abnormal sound during motor operation, which is crucial for predicting and preventing equipment failures. Through regular or continuous detection, maintenance or replacement of parts can be carried out in advance before serious problems occur in the equipment, avoiding production interruptions and high maintenance costs caused by sudden failures, thereby improving the reliability and stability of the equipment. By detecting and warning of equipment abnormalities in advance, sudden failures during high-load or high-speed operation can be avoided, reducing the safety risks faced by operators and improving the overall safety of the production environment. Therefore, the detection device for the rotary table provided in this embodiment can solve the technical problem in the prior art that the rotary table is prone to abnormal noise during actual work.

[0078] Specifically, the detection device of the rotary table includes an electronic detector, which is used to obtain the operating condition of the encoder, and determines whether the result of the detection operation is an abnormal state or a non-abnormal state according to whether the operating condition of the encoder meets the preset qualified operating condition. The detection device of the rotary table also includes an electronic device collector, which is used to obtain the operating sound condition of the motor of the rotary table 30 to be detected, and determines whether the result of the detection operation is an abnormal state or a non-abnormal state according to the operating sound condition of the motor.

[0079] like Figure 3As shown, the detection device of the rotary table includes an operating platform 10 and a mounting platform 20, wherein the mounting platform 20 is used to carry the rotary table 30 to be detected, and the operating platform 10 is located on one side of the mounting platform 20. The operating platform 10 provides an intuitive user interface through which the operator can start, control and stop the detection process. In addition, the operating platform 10 may be equipped with a display screen and an input device (such as a keyboard or a touch screen) for displaying the detection results, prompting information and receiving operation instructions, so that the detection process is more friendly and convenient for the operator. The operating platform 10 can summarize data from different detection devices (such as a recorder 50, a detector 60, etc.), and process and analyze the collected sound, image and signal data through the built-in analysis software, so as to draw a comprehensive conclusion about the health status of the rotary table. In this way, the operator can obtain comprehensive detection results on the operating platform 10 without having to view the data of each device separately. The operating platform 10 can display the detection data and the status of the rotary table in real time. Once the system detects an abnormality (such as the radial clearance of the motor bearing exceeds the preset range, the motor operation sound is abnormal, or the encoder data is inaccurate, etc.), the operating platform 10 will immediately issue an alarm to remind the operator to take corresponding measures. The operating platform 10 also has remote operation and monitoring functions, allowing operators to start and monitor the detection process in a control room far away from the rotary table 30 to be inspected, reducing the risk of operators being exposed to dangerous environments. At the same time, the remote monitoring capability allows the detection status of multiple devices to be centrally managed and analyzed, improving the efficiency of production management.

[0080] like Figure 4As shown, the detection device of the rotary table also includes a radio frequency transmitter 40, a recorder 50, a detector 60, an amplifier 70, a scanning transmitter 80, a scanning coil 90, a receiving coil 100, and a radio frequency coil 110. The radio frequency transmitter 40 is used to transmit radio frequency signals, which will penetrate the key components such as the motor and encoder of the rotary table to detect the internal structure and operating status. The design of the radio frequency transmitter 40 allows the detection process to be carried out under non-invasive conditions, reducing the impact on normal production, while improving the detection efficiency and safety. The radio frequency coil 110 is a key component connecting the radio frequency transmitter 40 and the detector 60, responsible for transmitting radio frequency signals to ensure the continuity and quality of the signal. The radio frequency signal emitted by the radio frequency transmitter 40 can be detected by the detector 60. The detector 60 can analyze the reflection of the signal, which is convenient for subsequent identification of possible abnormalities in the motor or encoder, such as component displacement, wear or cracks. The output end of the scanning transmitter 80 is connected to the input end of the scanning coil 90. The use of the scanning coil 90 improves the signal receiving efficiency and ensures the integrity and accuracy of the detection data. The receiving coil 100 is used to receive signals reflected from the inside of the motor. These signals contain important information about the structure and state of the motor, and the receiving coil 100 ensures that the signals can be accurately captured for subsequent analysis. The recorder 50 is used to record the detection results of the detector 60, including the reflection of the radio frequency signal and the image data of the internal structure of the motor. The detection signal obtained by the recorder 50 is amplified by the amplifier 70 for better identification and analysis.
