Abstract
Description
Technical Field
[0001] This utility model relates to the field of motor component testing technology, specifically to a stator testing device for motor production lines. Background Technology
[0002] Stator testing is a crucial step in motor manufacturing to ensure stator quality and performance. As a core component of the motor, the stator's performance directly impacts the motor's efficiency, stability, and lifespan. Traditional stator testing methods primarily rely on manual inspection or simple electrical performance tests. However, with advancements in motor technology and increased production automation, single testing methods are no longer sufficient to meet the demands for high precision and efficiency. Therefore, stator testing devices have emerged, integrating multiple sensing technologies such as acoustics, vibration, magnetic fields, and temperature. By monitoring the stator's operating status in real time, they can accurately identify problems such as core damage, winding defects, and magnetic asymmetry. The development of these testing devices stems from technological advancements in intelligent manufacturing, sensing technology, and data analysis, particularly the application of spectrum analysis, accelerometers, and acoustic sensor arrays. These advancements have enabled stator testing to achieve higher automation and accuracy, providing vital assurance for motor quality control.
[0003] Most existing stator testing devices are high-precision equipment. Although these devices can improve the accuracy of the test results, there may be some noise in the busy production line environment. If these devices are used to test the stator, especially for acoustic testing, this noise may interfere with the test and cause a decrease in the accuracy of acoustic testing.
[0004] In view of this, we propose a stator testing device for motor production lines. Utility Model Content
[0005] The purpose of this invention is to provide a stator testing device for motor production lines, addressing the problem that in busy production line environments, noise may exist, and using such devices for stator testing, especially acoustic testing, can interfere with the testing process, leading to a decrease in acoustic testing accuracy.
[0006] To achieve the above objectives, a stator testing device for a motor production line is provided, comprising a testing platform. A sound insulation plate is provided on the upper surface of the testing platform. A vertical plate and a testing instrument are installed on the testing platform inside the sound insulation plate, with the vertical plate and the testing instrument located on opposite sides of the upper surface of the testing platform. A mounting column is fixedly connected to the upper outer wall of the vertical plate. Slide grooves are provided on both sides of the testing platform below the mounting column. Support components are installed on both the slide grooves and the testing platform.
[0007] As a further improvement to this technical solution, an air layer is provided inside the sound insulation panel, a slide rail is fixedly connected to the front outer wall of the sound insulation panel, and a door panel is slidably connected to the slide rail.
[0008] As a further improvement to this technical solution, a connecting plate is fixedly connected to the inner wall of the sound insulation board, and sound-absorbing cotton is provided between the connecting plate and the sound insulation board.
[0009] As a further improvement to this technical solution, the support assembly includes a sliding column slidably connected inside the slide groove, a sliding rod fixedly connected to one outer wall of the sliding column, a support column fixedly connected to the top of the sliding column, and a soft pad provided on the outer surface of the support column.
[0010] As a further improvement to this technical solution, a fixing plate is fixedly connected to the surface of the detection platform on one side of the sliding column. The top of the fixing plate has four insertion holes, and the fixing plate below the insertion holes has a reserved opening that communicates with the insertion holes. The reserved opening is slidably connected to the sliding rod.
[0011] As a further improvement to this technical solution, a positioning bolt adapted to its size is installed in the socket, and the positioning bolt passes through the slide rod.
[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0013] In this stator testing device for motor production lines, sound insulation panels isolate noise generated in the production line environment, and sound-absorbing cotton absorbs the noise, thereby reducing the noise transmitted to the inside of the sound insulation panels. This reduces the interference of environmental noise on acoustic testing and ensures the accuracy of stator acoustic testing. At the same time, the use of support components allows for the sliding positioning and adjustment of various motor stators to support them, ensuring that the stator is in a stable state during testing. This reduces the impact of stator instability on testing and ensures the testing accuracy of the device. Attached Figure Description

[0023] Example 1
[0024] Please see Figures 1-4As shown, the purpose of this embodiment is to provide a stator testing device for a motor production line, including a testing platform 1. A sound insulation plate 2 is provided on the upper surface of the testing platform 1. A vertical plate 11 and a testing instrument 13 are installed on the testing platform 1 inside the sound insulation plate 2. The vertical plate 11 and the testing instrument 13 are respectively located on both sides of the upper surface of the testing platform 1. A mounting column 12 is fixedly connected to the upper outer wall of the vertical plate 11. Slide grooves 14 are provided on both sides of the testing platform 1 below the mounting column 12. Support components 3 are installed on both the slide grooves 14 and the testing platform 1. The stator can be installed by the mounting column 12. The testing instrument 13 can be powered on to test the stator. The slide grooves 14 provide a working environment for the support components 3.
[0025] In addition, an air layer is provided inside the sound insulation panel 2, and a slide rail 22 is fixedly connected to the front outer wall of the sound insulation panel 2. A door panel 21 is slidably connected to the slide rail 22. The sound insulation effect is improved by setting an air layer, which can further reduce the transmission of noise. The slide rail 22 ensures that the door panel 21 can be slidably used, which is convenient for the use of the device. A connecting plate 24 is fixedly connected to the inner wall of the sound insulation panel 2. Sound-absorbing cotton 23 is provided between the connecting plate 24 and the sound insulation panel 2. The connecting plate 24 provides support for the sound-absorbing cotton 23, which improves the rationality of the structure.
[0026] Furthermore, the support assembly 3 includes a sliding column 31 slidably connected inside the slide groove 14. A slide rod 35 is fixedly connected to one outer wall of the sliding column 31. A support column 32 is fixedly connected to the top of the sliding column 31. A soft pad is provided on the outer surface of the support column 32. By providing the soft pad, the support column 32 can avoid direct contact with the motor stator, reducing the wear of the stator and thus ensuring the service life of the stator. A fixing plate 36 is fixedly connected to the surface of the detection platform 1 on one side of the sliding column 31. The top of the fixing plate 36 has four insertion holes 33. The fixing plate 36 below the insertion hole 33 has a reserved opening 37 that communicates with the positioning bolt 34. The reserved opening 37 and the slide rod 35 are slidably connected. Through the reserved opening 37 and the slide rod 35 being slidably connected, the slide rod 35 can slide on the reserved opening 37, ensuring the adjustment of the sliding function of the slide rod 35. The positioning bolt 34, which is adapted to its size, is installed in the insertion hole 33, and the positioning bolt 34 is inserted through the slide rod 35. With this setting, the positioning bolt 34 can be inserted into different insertion holes 33 and can fix the slide rod 35 after insertion.
[0027] The specific working principle of this solution is as follows: The user can first slide the door panel 21 upwards to place the stator to be tested onto the mounting post 12. The support assembly 3 is adjusted according to the volume of the stator. For small stators, the user can hold the sliding rod 35 and slide it within the reserved opening 37. The sliding rod 35 drives the sliding post 31 to slide within the sliding groove 14, causing the support post 32 to gradually approach the stator. When the support post 32 contacts the stator, the user can insert the positioning bolt 34 into the corresponding insertion hole 33. The positioning bolt 34 restricts and positions the sliding rod 35. After the sliding rod 35 is fixed, the sliding post 31 and the support post 32 are simultaneously positioned. The support posts 32 on both sides simultaneously provide a certain support force to support the stator, thus ensuring the stability of the stator during testing. For large stators, the user can adjust the sliding posts 31 on both sides... The stator is slid backwards to accommodate different volumes of stators, and then the above operation is repeated to support and stabilize the stator. The detector 13 is connected to the motor electronics via an external power cord to test the stator. The user slides the door panel 21 down to cover the sound insulation board 2. When the noise generated in the production line environment encounters the sound insulation board 2, some of the sound waves are reflected back by the material surface, and some of the sound waves penetrate the material and continue to propagate. The sound insulation board 2 reflects more sound waves, thereby reducing the transmission of sound. During the propagation of sound waves, the penetrating sound waves are absorbed into the sound-absorbing cotton 23, and then the energy is dissipated by multiple reflections and scatterings inside the sound-absorbing cotton 23. As a result, most of the sound wave energy is absorbed by the sound-absorbing cotton 23, thereby reducing the propagation of sound and reducing the interference of noise on the detection accuracy.
