Abstract
Description
Technical Field
[0001] This utility model relates to the field of servo motor testing technology, specifically a small servo motor sound detection device. 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 will change systematically, 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 wide variety of small motor sizes and frame dimensions makes manual operation cumbersome due to frequent fixture changes. Utility Model Content

[0022] 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.
[0023] See Figure 1This embodiment provides a small servo motor sound detection device, including a detection platform 10, on which a sealed chamber 11 is set. The sealed chamber 11 is an openable structure, as shown in the figure. It has a flip cover, which is driven to rotate 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. A positioning base plate 12 is set inside the sealed chamber 11. The edge of the positioning base plate 12 is provided with three first positioning side plates 13 and one second positioning side plate 14. A mounting bracket 15 is set on one side of the positioning base plate. A sound sensor (not shown in the figure) and a microphone 17 are set on the mounting bracket 15. A pressing device 16 is also set on one side of the positioning base plate. The pressing device 16 is used to press the motor to be tested towards the first positioning side plate 13.
[0024] Specifically, a mounting plate 18 is also provided at the bottom of the sealed chamber 11. The mounting plate 18 has a buffer structure, such as a spring. The positioning base plate 12 is set on the mounting plate with the buffer structure by multiple support columns. By setting the buffered base plate, it plays a buffering and protection role when placing the motor to be tested.
[0025] like Figure 2 As shown, the clamping device 16 includes a slide rail 161 mounted on the mounting plate, a movable plate 162 mounted on the slide rail 161, a buffer plate 163 mounted on the movable plate 162, and an elastic pressure head mounted on the buffer plate 163. The elastic pressure head can be made of rubber. A quick clamp 164 is mounted on the mounting plate. The output end of the quick clamp 164 is connected to the movable plate 162 and is used to drive the movable plate to move and clamp towards the first positioning side plate 14.
[0026] In addition, in order to detect whether the motor to be tested on the positioning base plate 12 is placed in place, a position sensor 165 is also installed on the buffer pressure plate 163, and a wire hanging plate 19 is also installed in the sealed chamber to organize the wire harness in the chamber.
[0027] To facilitate the adjustment of the position of the sound sensor, an adjustment device is provided on the mounting bracket 15. First, the adjustment device can move up and down along the mounting bracket. It is composed of multiple rotatable adjustment rods, thereby achieving free rotation in the horizontal and vertical directions. Then, the sound sensor and microphone 17 are installed on the adjustment rods.
[0028] Working principle: First, the operator scans the code of the motor 20 to be tested and records the product SN number. Then, the sealed door is opened, and the operator places the motor on the positioning base plate and positions it using the positioning side plates on both sides. Then, the operator pushes the quick clamp to drive the buffer plate to press the motor. The start button is pressed, the door is closed, the sound sensor and microphone collect sound signals at the same time, and the test results are uploaded. Then, the door is automatically opened, and the operator unloads the motor.
[0029] 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.
