Description

Technical Field

[0001] This utility model relates to the field of electronic rotor housing technology, specifically a motor rotor housing testing platform. Background Technology

[0002] With the advancement of science and technology, electric motors have been widely used in various industries both domestically and internationally. Since motors rotate at high speeds during operation, maintaining their stability is crucial. This improves operating efficiency and extends service life. Currently, the motor rotor housing is a bowl-shaped shell. Whether its overall structure is within the allowable tolerances determines the overall stability of the motor after assembly. The smaller the tolerances, the more stable the motor, resulting in higher stability after assembly and a longer rotor life, thus extending the overall lifespan of the motor. Conversely, larger tolerances lead to a shorter overall lifespan. Therefore, it is necessary to inspect the specifications and quality of the motor rotor housing during manufacturing.

[0003] For example, Chinese utility model patent CN210426318U discloses a motor rotor housing inspection platform, including a base. A positioning rod is fixedly connected to the top center of the base, and a visualization measurement mechanism is installed on the base. The visualization measurement mechanism includes a sleeve, which is vertically positioned above the base and fixed to the base by a lifting rod and a lateral telescopic rod. A vertical rod passes through the sleeve, and the vertical rod is slidably limited to the sleeve. A measurement reading mechanism is installed on the vertical rod. This platform can detect the distance between the side wall of the motor housing cavity and the central axis, providing comprehensive detection, convenient operation, and controllable detection efficiency. The reading visualization magnification mechanism magnifies the small tolerances of the side wall of the housing cavity, facilitating their discovery during the inspection process.

[0004] However, the existing motor rotor housing inspection station is not convenient for inspecting the overall height and width of the motor rotor housing.

[0005] Therefore, we propose a motor rotor housing testing platform to solve the above problems. Utility Model Content

The scale line 16 is set to facilitate the intuitive display of the difference between the value indicated by the moving pointer 14 and the value indicated by the auxiliary reference pointer 17.

[0024] Example 2:

[0025] Please see Figure 1-3 This is the second embodiment of the present invention. Based on the previous embodiment, the positioning rod 3 is fixedly connected to the top surface of the workbench 1. When placing the motor rotor cover, the positioning rod 3 can be inserted to prevent the motor rotor cover from falling off the workbench 1.

[0027] A sliding block 71 is fixedly connected to one side of the movable positioning plate 7, and a sliding groove 21 is opened on one side of the fixed frame 2. The sliding block 71 is slidably connected to the sliding groove 21 to improve the stability of the movement of the movable positioning plate 7.

[0028] The moving pointer 19 is slidably connected to one side of the worktable 1, and the value of the scale line 18 indicated by the moving pointer 19 can be observed.
