[0002] A top-loading washing machine is a cleaning appliance that uses electrical energy to generate mechanical action to wash clothes. It mainly consists of a casing, a vertical washing and spin-drying tub, and a pulsator located at the bottom of the washing and spin-drying tub.

[0003] As the core agitator component, the washing machine's impeller may experience instability in its center of gravity after production, leading to significant vibrations during high-speed rotation and affecting the machine's performance. Summary of the Invention

[0004] To facilitate monitoring the quality of a washing machine pulsator, this application provides a rotating base for testing a washing machine pulsator.

[0005] This application provides a rotating base for detecting the impeller of a washing machine, which adopts the following technical solution:

[0006] A rotating base for detecting a washing machine impeller includes a mounting base with a through groove, a rotating shaft and a bearing. The top of the mounting base has a mounting groove for accommodating the bearing. The rotating shaft passes through the through groove and is rotatably mounted on the mounting base via the bearing. The end of the rotating shaft protruding from the mounting base is used for coaxial connection with the impeller.

[0007] By adopting the above technical solution, when it is necessary to test the quality of the washing machine pulsator, the mounting base is placed on the testing table, the pulsator is installed on the end of the rotating shaft that protrudes from the mounting base, and the rotating shaft is rotatably mounted on the mounting base through a bearing. The bearing ensures the smooth rotation of the rotating shaft. A height gauge is set on the testing table, which abuts against the upper surface of the edge of the pulsator. By rotating the pulsator, the operator reads the data on the height gauge to monitor the vibration amplitude when the pulsator rotates, thereby detecting whether the pulsator meets the quality requirements. The quality of the washing machine pulsator can be conveniently monitored through the testing device.

[0008] Optionally, a mounting post is provided at the top of the rotating shaft. The mounting post is used to insert into the impeller shaft. A mounting bolt is threaded to the end of the mounting post, and the impeller shaft is coaxially fixed to the mounting post by the mounting bolt.

[0009] By adopting the above technical solution, the mounting column facilitates the installation and positioning of the impeller, and the mounting bolts ensure the impeller is securely installed.

[0010] Optionally, the top circumferential outer wall of the mounting column is provided with a plurality of toothed grooves, which are provided for the impeller to mesh and adapt.

[0011] By adopting the above technical solution, the impeller rotation is stabilized through the tooth groove, and the impeller is not easy to rotate alone.

[0012] Optionally, it also includes a second bearing, and the bottom of the mounting base is provided with a mounting groove for the second bearing to be accommodated, and the bottom of the rotating shaft is rotatably connected to the mounting base through the second bearing.

[0013] By adopting the above technical solution, the rotational stability of the shaft is further improved by bearing two, thus improving the accuracy of detection.

[0014] Optionally, a limiting ring block is provided on the rotating shaft, and the limiting ring block abuts against a surface of the bearing.

[0015] By adopting the above technical solution, the installation and positioning of the rotating shaft can be facilitated by setting a limiting ring block.

[0016] Optionally, the limiting ring block is integrally formed with the rotating shaft.

[0017] By adopting the above technical solution, the limiting ring block and the rotating shaft are integrally formed, resulting in high structural strength.

[0018] In summary, this application includes at least one of the following beneficial technical effects:

[0019] 1. When it is necessary to test the quality of the washing machine impeller, the impeller is installed on the end of the shaft protruding from the mounting bracket. By rotating the impeller, the shaft is rotated, and the operator reads the data on the height gauge to check whether the impeller meets the quality requirements. The quality of the washing machine impeller can be easily monitored through the testing device.

[0020] 2. The impeller is securely installed using toothed grooves and mounting bolts, ensuring it rotates only with the shaft.

[0021] 3. The limiting ring block facilitates the installation and positioning of the rotating shaft. Attached Figure Description
