[0024] Embodiment 3, on the basis of embodiment 2, a self-locking wheel 33 is fixedly mounted on the secondary rotating shaft 23, a self-locking groove 34 is provided on the self-locking wheel 33, a group of self-locking grooves 34 are symmetrically arranged, a primary piston seat 36 is fixedly connected to the base 1 through a primary bracket 35, a primary piston 37 is movably arranged in the inner cavity of the primary piston seat 36, the upper side end of the primary piston 37 is fixedly connected to a force rod 38, and the lower side end of the primary piston 37 is fixedly connected to a support spring 39, and the base 1 is fixed by a secondary bracket 41 A secondary piston seat 42 is installed, and a secondary piston 43 is movably installed in the inner cavity of the secondary piston seat 42.

By installing the self-locking wheel 33 on the secondary rotating shaft 23 and arranging the push rod 40 on the side wall of the power rod 31, when the power rod 31 is pressed down, the push rod 40 will generate a downward pressure on the force-bearing rod 38, so that the primary piston 37 moves downward, thereby increasing the internal cavity pressure of the primary piston seat 36, thereby pushing up the secondary piston 43, so that the end of the engaging rod 44 is embedded in the self-locking groove 34, so that the self-locking wheel 33 is stuck, thereby effectively ensuring the stability of the component 6 to be processed during the processing.

[0026] The end of the engaging rod 44 is hemispherical. When the reset spring 45 is in the reset state, the engaging rod 44 is completely disengaged from the self-locking groove 34 , making it easier for the engaging rod 44 to align and enter the self-locking groove 34 .

10. The punching auxiliary mechanism for motor parts processing according to claim 9, characterized in that: The end of the locking rod (44) is hemispherical, and when the reset spring (45) is in the reset state, the locking rod (44) is completely disengaged from the self-locking groove (34).
