[0002] The motor rotor is assembled by an iron core and a rotor shaft. The inner wall of the iron core and the outer surface of the rotor shaft are in interference fit and need to be connected by a riveting machine.

[0003] The Chinese patent discloses a one-piece riveting and locking device for a generator rotor, with the publication number CN115995928A, which includes an upper riveting mechanism, a lower riveting mechanism, and a tooling plate. Among them: the upper riveting mechanism is arranged above the lower riveting mechanism, the tooling plate is arranged between the upper riveting mechanism and the lower riveting mechanism, and the generator rotor is placed on the tooling plate. The upper and lower claw poles of the generator rotor are simultaneously riveted by the upper riveting mechanism and the lower riveting mechanism respectively. The present invention can simultaneously rivet the upper and lower claw poles of the generator rotor, and there will be no riveting grooves inside the claw poles, making the assembly between the upper and lower claw poles and the rotor coil tighter. It can realize the one-piece riveting and locking of the generator rotor, increase the contact area between the rotor coil and the upper and lower claw poles, increase the magnetic flux, and improve the power generation efficiency; there is no need to rivet inside the claw poles, reducing the riveting process, which is beneficial to reducing production costs and improving actual production efficiency.

[0004] However, it still has the following disadvantages: The device uses the upper pressing head to press down the rotor shaft to connect the rotor shaft and the iron core, but the device does not position the rotor shaft. When installing the rotor shaft, manual feeding is required, and the operator needs to hold the rotor shaft vertically, resulting in low safety. For this reason, we propose a tooling device suitable for rotor riveting to solve this problem. Content of the Utility Model
