Description

Technical Field

[0001] The utility model belongs to the technical field of pneumatic measuring instruments, and more specifically, relates to a device for detecting the inner circle of a motor stator core. Background Art

[0002] The pneumatic measuring instrument can accurately measure the diameter and roundness of the inner circle of the motor stator core, which is of great significance for ensuring the stability and reliability of the motor performance. During the detection process, the pneumatic measuring instrument ejects air through the nozzle, and the airflow changes due to the size of the inner circle of the stator core. The sensor captures the airflow change, converts it into an electrical signal, and calculates and analyzes it through the processing system to obtain information such as the inner circle size and roundness. The existing pneumatic measuring instrument for detecting the inner circle of the motor stator core is generally composed of an operating table, a display console, a connecting seat, and an inner circle probe fixed on the connecting seat.

[0003] Existing application number: CN202321515086.2, the utility model relates to a buoy-type pneumatic measuring instrument, including a buoy-type pneumatic measuring instrument body, a base is fixed on the lower surface of the buoy-type pneumatic measuring instrument body, and a scale tube is fixed on the front of the buoy-type pneumatic measuring instrument body. When the buoy-type pneumatic measuring instrument body is placed on an uneven table, four hand wheels can be rotated by hand respectively, and then the rotation of the four hand wheels drives the four threaded rods to rotate inside the four threaded holes and move downward respectively, and then the anti-slip pads fixed on the lower surfaces of the four support blocks respectively contact the table, and then the four support blocks can stably support the buoy-type pneumatic measuring instrument body on the table, and make the buoy-type pneumatic measuring instrument perpendicular to the horizontal plane, and at the same time, the four support blocks can increase the contact area between the base and the table, thereby improving the stability of the buoy-type pneumatic measuring instrument body when placed on the table.

[0004] Based on the above, when the stator core is placed on the outside of the inner circle probe for inspection, in order to ensure that all parts of the inner circle of the stator core can be fully and accurately measured, the stator core must be rotated completely. However, this process requires the core to be lowered and rotated again multiple times, which is a cumbersome and time-consuming operation. Each lowering and re-rotation may introduce errors, affecting the accuracy of the measurement. Utility Model Content

[0060] The rotating assembly includes:

[0061] Transmission rack 602, which is fixedly connected to the left side of the guide rod 6;

[0062] The transmission gear 7, the bottom of the transmission gear 7 is connected to the inside of the transmission box 3, and the transmission gear 7 is engaged with the transmission rack 602. The effect is to pull the pull ring 601 to the right and drive the guide rod 6 to move synchronously.
