[0024] A support frame 412 is fixedly connected to the processing machine tool 1; a lifting mechanism 413 is installed on the top of the cross bar of the support frame 412; a lifting rod 414 is installed at the bottom of the lifting mechanism 413; a conical pressing block 415 is installed at the bottom of the lifting rod 414; a pressing rod 416 is fixedly connected to the top of the pressing block 415; the vertical center line of the pressing block 415 coincides with the vertical center line of the ring plate 402; the cross-sectional diameter of the fixing rod 404 is smaller than the width of the limiting hole 406; the movement track of the fixing rod 404 is always located inside the limiting hole 406; a rotating base 407 is installed on the top of the processing machine tool 1; a pressure sensing device is arranged on the top of the rotating base 407, and a control device is installed at the bottom of the pressure sensing device; the cross-sectional dimension diameter of the rotating base 407 is smaller than the cross-sectional dimension diameter of the ring plate 402; when the limiting plate 403 is in a vertical state, the bottom of the limiting plate 403 does not contact the processing machine tool 1; when the spring 405 is not acting, it does not deform, and at this time the limiting plate 403 is in an inclined state; the height of the pressing block 415 is smaller than the height of the support plate 401;

[0025] During operation, in the production and processing of the motor core, a processing mold is required to fix the motor core and perform specified processing operations. When the existing processing mold that is convenient for fixing is in use, the fixed position of the core will shift. Not only does it require repeated adjustment of the fixed position of the core, but it also affects the accuracy of subsequent processing operations. In this application, the auxiliary positioning device is used. The core to be processed is placed within the working range of the annular plate 402. The motor core is placed on the top of the limiting plate 403. The lifting mechanism 413 on the support frame 412 is started, and the lifting rod 414 pushes the pressing block 415 and the pressing rod 416 to move downward. When the pressing block 415 contacts the motor core, it continues to move downward, causing the center line of the motor core to gradually coincide with the center line of the pressing block 415. Moreover, the pressing block 415 exerts a downward pushing force on the motor core, and the limiting plate 403 rotates under the force. With the cooperation of the fixed rod 404 and the limiting hole 406, the springs 405 at the four corners contract and generate a reaction force, making the center line of the motor core completely coincide with the center line of the pressing block 415, achieving precise positioning of the core and eliminating the need for repeated adjustment of the fixed position of the core.

[0027] During operation, when the motor core is on the top of the rotating base 407, with the cooperation of the control device and the pressure sensing device, the telescopic mechanism 409 on the fixed plate 408 operates, and the telescopic rod 410 pushes the clamping block 411 towards the motor core, making the motor core accurately fixed at the center position of the annular plate 402, avoiding the shift of the core during the processing and ensuring the accuracy of subsequent processing operations.

[0028] Working principle: During the production and processing of the motor iron core, it is necessary to use a processing mold to fix the motor iron core and perform specified processing operations; when the existing processing mold that is convenient for fixing is in use, the fixed position of the iron core will shift. Not only does it require repeated adjustment of the fixed position of the iron core, but it also affects the accuracy of subsequent processing operations. This application functions through an auxiliary positioning device. The iron core to be processed is placed within the working range of the annular plate 402, and the motor iron core is placed on the top of the limiting plate 403. The lifting mechanism 413 on the support frame 412 is started, and the lifting rod 414 pushes the pressing block 415 and the pressing rod 416 to move downward. When the pressing block 415 contacts the motor iron core, it continues to move downward, causing the center line of the motor iron core to gradually coincide with the center line of the pressing block 415, and the pressing block 415 applies a downward driving force to the motor iron core. The limiting plate 403 rotates under the force. With the cooperation of the fixed rod 404 and the limiting hole 406, the springs 405 at the four corners contract and generate a reaction force, causing the center line of the motor iron core to completely coincide with the center line of the pressing block 415. When the motor iron core is located on the top of the rotating base 407, with the cooperation of the control device and the pressure sensing device, the telescopic mechanism 409 on the fixed plate 408 operates, and the telescopic rod 410 pushes the clamping block 411 towards the motor iron core, enabling the motor iron core to be accurately fixed at the center position of the annular plate 402. This achieves precise positioning of the iron core, eliminates the need for repeated adjustment of the fixed position of the iron core, avoids the shift of the iron core during the processing process, and ensures the accuracy of subsequent processing operations.
