Description

Technical Field

[0001] This utility model relates to the field of click detection technology, specifically a sound detection device for medium and large servo motors. Background Technology

[0002] As a core actuator in precision control systems, the operating status of servo motors directly affects the performance and reliability of the entire equipment. Sound signal detection, as a non-invasive, low-cost, and information-rich monitoring method, is gradually becoming an important technological direction for servo motor condition monitoring and fault diagnosis. From a fundamental perspective, the sound generated during motor operation contains various components such as mechanical vibration, electromagnetic noise, and aerodynamic noise. These acoustic characteristics are strongly correlated with the internal state of the motor. When a motor experiences faults such as bearing wear, rotor eccentricity, poor component assembly, or winding insulation damage, its acoustic characteristics undergo regular changes, providing a physical basis for sound-based fault diagnosis. Currently, sound analysis relies heavily on sound analysis technicians for manual online listening, and multiple professionals are needed to simultaneously listen and determine the cause of anomalies. Furthermore, the weight and size of the tested motors make them difficult to handle easily with existing testing equipment. Utility Model Content

[0024] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0025] See Figures 1-3This embodiment provides a sound detection device for medium and large servo motors, including a detection platform 10. A sealed chamber 11 is set on the detection platform. The sealed chamber 11 is an openable structure, as shown in the figure. It has a flip cover. The flip cover is rotated by a cylinder or hydraulic rod to open or close the sealed chamber. In order to further improve the sealing effect, sound insulation cotton and sealing gaskets can be set inside the sealed chamber to improve the sound insulation effect and improve the detection accuracy.

[0026] The sealed chamber 11 is equipped with a positioning component 12 for positioning the motor to be tested. The positioning component 12 includes a mounting base plate 121, two sets of tension rails 122 are provided on the mounting base plate 121, a positioning plate 123 is provided on the tension rails 122, a movable plate 124 is movably provided on the positioning plate 123, and two sets of support blocks 125 are provided on the movable plate 124. The support blocks 125 have support grooves adapted to the shape of the motor to be tested for placing the motor to be tested.

[0027] More specifically, two rows of rollers 126 are provided below the movable plate 124, and two sets of guide grooves 127 are provided on the positioning plate 123. The two rows of rollers 126 can move within the range of the guide grooves 127, thereby enabling the positioning plate 123 and the movable plate 124 to be pulled out from the sealed chamber.

[0028] In addition, a first limiting plate 17 is provided on the mounting base plate to limit the movement of the positioning plate 123. A first position sensor 18 is provided on the first limiting plate 17 to detect whether the positioning plate is in position. At the same time, a second limiting plate 19 is provided on the positioning plate 123 to limit the movement of the moving plate 124. A second position sensor 20 is provided on the second limiting plate 19 to detect whether the moving plate is in position.

[0029] To further secure the motor to be tested, a cylinder mounting bracket 128 is also provided on the mounting base plate 121. A clamping cylinder 129 is provided on the cylinder mounting bracket 128, and a pressure plate is provided at the output end of the clamping cylinder 129 for clamping the motor to be tested from above.

[0030] To facilitate the loading and unloading of the motor, a transfer conveyor is set at the entrance of the sealed chamber. The transfer conveyor includes a base plate 13 set on the inspection platform. Multiple circular holes 131 are arranged in an array on the base plate 13. Ball bearings 132 are installed in the circular holes 131 to facilitate the movement of the moving plate on the base plate 13. Baffles 133 are set on both sides of the base plate 13. Of course, there is a gap in the baffle on the side closer to the sealed chamber for the moving plate to enter and exit.

[0031] In addition, to facilitate manual transfer of the movable plate equipped with the motor, handles are provided in different directions on the movable plate 124. Similarly, handles are also provided on the positioning plate 123. The height of the base plate 13 is basically the same as the height of the positioning plate 123 inside the cabin, so as to facilitate the transfer of the movable plate between the inside and outside of the cabin. A wire hanging plate 14 is also provided inside the sealed cabin for organizing the wire harness inside the cabin.

[0032] To achieve the sound detection function, a sensor mounting bracket 15 is set on the mounting base plate 121. An adjustment device is set on the sensor mounting bracket 15. First, the adjustment device can move up and down along the mounting bracket. It is composed of multiple rotatable adjustment rods, which can then be freely rotated in the horizontal and vertical directions. A sound sensor is set on the adjustment rod. In order to improve the detection accuracy, a microphone is also set on the adjustment rod.

[0033] Due to the heavy weight of medium and large motors, two sets of I-shaped support plates 16 are set below the mounting base plate 121. A buffer structure, such as a buffer spring, is set on the support plate 16. The mounting base plate 121 is connected to the buffer structure through multiple columns, thereby achieving a buffering effect when the motor is placed.

[0034] Working principle: The motor to be tested is placed on the carrier on the transfer line. The operator scans the product code and records the product serial number. The sealed door is automatically opened, the carrier on the line is pulled to the door, the positioning plate inside the sealed chamber is pulled outward, and the moving plate outside the chamber is pushed onto the positioning plate inside the chamber. The second position sensor detects this. The operator pushes the positioning plate inside the chamber into the equipment, and the first position sensor detects this. Pressing the start button closes the sealed door, the clamping cylinder presses down, and the sound sensor and microphone simultaneously collect sound signals and upload the test results. After the test is completed, the sealed door automatically opens, the operator pulls out the positioning plate inside the chamber, pulls out the moving plate, and then unloads the material.

[0035] 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.
