During the production process of the brushless motor, the motor shaft and the casing generally need to be press-fitted and fixed through a sleeve to complete the molding of the brushless motor casing. After the press-fitting production of the brushless casing is completed, the casing needs to be subjected to corresponding concentricity testing. However, conventional testing generally involves removing the casing from the press-fitting equipment and moving it to the required testing device for installation. This method of manually moving and installing the casing for testing is not only time-consuming and labor-intensive, and reduces the production efficiency of the casing, but also requires workers to always pay attention to the production of the casing and move and install it, greatly increasing the labor intensity required for workers' production, reducing production and processing efficiency, and increasing the time cost of workers' processing and production.
