Description

Technical Field

[0001] The utility model relates to the field of motor production equipment, and more specifically, to a motor stator testing device. Background Art

[0002] After the stator is produced and processed, it is necessary to conduct a series of tests such as leakage on the stator before the motor assembly operation can be carried out. At present, the leakage detection of the motor stator is generally carried out manually through equipment such as leakage detectors and voltage testers, and its detection efficiency is relatively slow. In order to improve the efficiency of motor stator leakage detection, for example, the utility model patent with authorization announcement number CN220552956U discloses a motor stator testing device for motor stator leakage, which is installed on the base through the stator mounting seat through the turntable rotation, so that the stator can be flexibly adjusted after installation. The adjustment seat can be close to or away from the stator mounting seat to control the distance between the test needle and the stator product to be measured. The lifting seat is used to adjust the height of the test needle, and the translation seat is used to adjust the horizontal position of the test needle. However, when the above-mentioned motor stator testing device is in use, it is necessary to install and disassemble the motor stator on the motor stator testing device before and after each test. The interval between the two tests is too long, and the single test time is too long, which will also affect the motor stator detection efficiency. Utility Model Content

[0003] The purpose of the utility model is to provide a motor stator testing device, which can effectively shorten the detection time and thus improve the detection efficiency of the motor stator.

When the first rotating disc rotates, it can drive any of the second rotating discs to rotate until it is transmission-connected to the second driving mechanism.

[0007] A leakage test unit is arranged on the workbench and is transmission-connected to the moving mechanism.

[0025] The present invention will be described in further detail below in conjunction with the accompanying drawings so that those skilled in the art can implement the invention with reference to the description.

[0026] It should be noted that, in the description of the present invention, the terms "horizontal", "longitudinal", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description. They do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0027] Figure 1-Figure 3 An embodiment of the present invention provides a motor stator testing device, comprising:

[0028] The workbench 1 has a first drive mechanism 2 and a second drive mechanism 3 at its upper end; the first drive mechanism 2 can be an existing electric rotation device;

[0029] A first rotating disc 4 is transmission-connected to the first driving mechanism 2. A plurality of second rotating discs 5 are uniformly distributed along the circumference of the first rotating disc 4 and rotationally connected thereto. The second rotating discs 5 are provided with a positioning assembly for fixing the stator. When the first rotating disc 4 rotates, it can drive any of the second rotating discs 5 to rotate until it is transmission-connected to the second driving mechanism 3.

[0030] The leakage test unit 6 is disposed on the workbench 1 and is in transmission connection with the moving mechanism. The driving mechanism drives the leakage test unit 6 to move horizontally or vertically. The leakage test unit 6 can be made of existing technology, such as the test needle disclosed in the utility model patent with authorization announcement number CN220552956U.

[0031] In this embodiment, when the motor stator test device is working, the location of the leakage test unit 6 is used as the detection position. The motor stator 16 is horizontally fixed on the second rotating disc 5 by the positioning assembly. When the second rotating disc 5 rotates to the detection position, it is connected to the second driving mechanism 3. The driving mechanism drives the leakage test unit 6 to move horizontally until it contacts the outer side of the motor stator 16, and then starts the detection. During the detection process, the second driving mechanism 3 drives the motor stator 16 to rotate, and the driving mechanism drives the leakage test unit 6 to move up and down. The first driving mechanism 2 drives the first rotating disc 4 in a stepping manner, for example Figure 1 In the motor stator testing device shown in FIG, six second rotating discs 5 are provided. The first driving mechanism 2 drives the first rotating disc 4 to rotate 60 degrees each time, so that each second rotating disc 5 moves to the leakage test unit 6 in sequence. At this time, the moving mechanism drives the leakage test unit 6 to move to the outer wall of the motor stator 16 on the second rotating disc 5 to contact the outer wall of the motor stator 16, so that the motor stator 16 can be tested for leakage. After the test is completed, the driving mechanism drives the leakage test unit 6 away from the motor stator 16 without affecting the rotation of the first rotating disc 4. When the motor stator testing device is working, two other positions on the workbench 1 are selected as the loading position and the unloading position, so that during the rotation process, three second rotating discs 5 can be rotated to the detection position, the loading position and the unloading position respectively, and then the stator leakage test, the loading of the motor stator 16 to be tested and the unloading of the motor stator 16 to be tested are respectively performed, thereby avoiding the loading and unloading of the motor stator 16 causing the single test time to be too long, shortening the single test time, and thus improving the detection efficiency of the motor stator 16.

[0032] Preferably, as another embodiment of the present invention, the second driving mechanism 3 includes:

[0033] A plurality of first gears 7, a rotating shaft 8 is provided at the lower end of the second rotating disc 5, the rotating shaft 8 passes through the first rotating disc 4 and is rotatably connected thereto, and each of the rotating shafts 8 is coaxially connected to the first gear 7;

[0034] A lifting unit, which is arranged below the workbench 1 through a bracket;

[0035] The drive motor 10 has an output shaft arranged upward, and its casing is connected to the lifting unit. A through hole corresponding to the drive motor 10 is provided on the workbench 1, and the drive motor 10 passes through the through hole; the output shaft of the drive motor 10 is arranged upward and coaxially connected to the second gear 11; the lifting unit is a telescopic cylinder, the cylinder body of the telescopic cylinder is connected to the bracket, and its telescopic rod is arranged vertically upward and connected to the drive motor 10.

[0036] In this embodiment, when the first rotating disc 4 is in operation, the lifting unit drives the drive motor 10 downward to ensure the rotation of the first rotating disc 4. After the first rotating disc 4 stops rotating, the lifting unit drives the drive motor 10 upward, causing the second gear 11 to move upward to engage with the first gear 7 located at the detection position. During this process, if the angle of the first gear 7 is not exactly engaged with the second gear 11, the force exerted by the second gear 11 on the first gear 7 will also cause the rotating shaft 8 on the first gear 7 to rotate slightly, and the first gear 7 to rotate slightly, thereby engaging with the second gear 11. When the drive motor 10 is in operation, it drives the second rotating disc located at the detection position to rotate, thereby causing the stator 16 of the motor to be tested to rotate.

[0037] Preferably, as another embodiment of the present invention, the positioning assembly includes:

[0038] a bottom plate 12 detachably connected to the second rotating disc 5;

[0039] The positioning cylinder 13 is disposed on the upper end of the base plate 12 and is coaxial with the second rotating disk 5 .

[0040] In this embodiment, multiple base plates 12 can be provided, with the radii of the positioning cylinders 13 on the upper ends of different base plates 12 varying to accommodate motor stators 16 having different inner diameters. To achieve a removable connection between the base plate 12 and the second rotating disk 5, a non-cylindrical positioning groove can be provided on the upper end of the second rotating disk 5, and a corresponding positioning block can be provided on the lower end of the base plate 12. The positioning block is embedded in the positioning groove to secure the base plate 12 to the second rotating disk 5. The motor stator 16 can then be placed on the second rotating disk 5, with the outer diameter of the positioning cylinder 13 matching the inner diameter of the motor stator 16, securing the motor stator 16 via the positioning cylinder 13.

[0041] Preferably, as another embodiment of the present invention, the moving mechanism includes:

[0042] A first linear module 14 is horizontally arranged on the workbench 1;

[0043] The second linear module 15 is vertically arranged and connected to the slider of the first linear module 14 . The leakage test unit 6 is connected to the slider of the second linear module 15 .

[0044] In this embodiment, the horizontal movement and the vertical movement of the leakage test unit 6 are respectively achieved by the first linear module 14 and the second linear module 15 .

[0045] Although the embodiments of the present invention have been disclosed above, they are not limited to the applications listed in the description and implementation methods. They can be fully applied to various fields suitable for the present invention. For those familiar with the art, additional modifications can be easily implemented.
