Thus, the yield rate is higher and unnecessary losses during the production process are reduced.

[0016] The beneficial effects of the present invention are as follows:

[0017] By providing the rotating column, the bearing body, the rotor body and the main body of the mounting shaft are respectively installed in the moving box, the fixed box and the storage box, so that the bearing body, the rotor body and the main body of the mounting shaft respectively enter the press-fitting groove. Among them, the motor II drives the lead screw I to rotate, and the lead screw I drives the lifting plate and the connecting frame to move. The lifting plate and the connecting frame drive the lifting baffle to move, and the lifting baffle drives the bearing body to move into the press-fitting groove. The main body of the mounting shaft falls on the moving block and the placement block. Start the hydraulic press body, the hydraulic press body drives the hydraulic column to move, the hydraulic column drives the moving block to move, so that the main body of the mounting shaft is clamped into the moving block, and the moving block drives the main body of the mounting shaft to be pressed into the rotor body and the bearing body in sequence. Reset the hydraulic column, the spring II drives the slider to move, the slider drives the moving block to move, the moving block drives the main body of the mounting shaft to move, and the main body of the mounting shaft drives the rotor body and the bearing body to move, so that the bearing body is separated from the lifting baffle. Start the motor II to drive the lifting baffle to rise and separate from the rotating column, and the lifting baffle drives the bearing body in the moving box to be received into the moving box, which is beneficial to the device to control that only one rotating shaft body is in the press-fitting groove each time the bearing body is press-fitted on the main body of the mounting shaft, preventing multiple rotating shaft bodies from falling into the press-fitting groove for press-fitting, resulting in collision damage between multiple components. Rotate the lead screw II, the lead screw II drives the moving box to move, the moving box drives the lifting baffle to move, and the lifting baffle drives the bearing body to move along the press-fitting groove, which is beneficial to the device to change the installation position of the bearing body on the main body of the mounting shaft according to actual needs and expand the applicability of the device. When the rotor body moves to one end of the press-fitting groove and stops, the spring II pushes the moving block to separate from the main body of the mounting shaft. Start the motor I, the motor I drives the rotating shaft to rotate back and forth, the rotating shaft drives the rotating column to rotate, the rotating column drives the press-fitting groove to rotate, the press-fitting groove drives the press-fitted components to rotate to the lower part of the device and makes the components separate from the rotating column, and at the same time, the press-fitting groove rotating to the upper part of the rotating column presses the components again, which is beneficial to preventing the device from needing to stop production first during the disassembly of components, resulting in the device being unable to disassemble the press-fitted components while carrying out the press-fitting production of components, affecting the production and manufacturing efficiency of the device.

[0018] Through the provided card holder, after a component is successfully press-fitted in the press-fitting groove, the second motor is started. The second motor drives the first lead screw to rotate. The first lead screw drives the lifting plate to move. The lifting plate drives the connecting frame to move. The connecting frame drives the extrusion block to move. The extrusion block drives the inclined plate to move. The inclined plate drives the connecting rod to move. The connecting rod drives the card holder to move, causing the card holder to disengage from the rotor body. The rotor body then falls into the press-fitting groove. After the lifting plate resets, the first spring drives the moving plate to move. The moving plate drives the card holder to reset and hold the subsequent rotor body. This is beneficial for the device to control the frequency of the rotor body entering the press-fitting groove in accordance with the press-fitting frequency of the device, preventing the rotor body from getting stuck in the rotating column when it falls into the press-fitting groove, which could damage the device and its components, and improving the production fluency and safety of the device.

[0019] Through the provided movable plate, the first motor drives the rotating column to rotate back and forth. The rotating column drives the rotating plate to rotate back and forth. The rotating plate squeezes the movable plate to move. The movable plate drives the discharge groove to move. When the discharge groove passes by the storage groove, the mounting shaft body falls into the discharge groove. The movable plate drives the mounting shaft body to fall into the press-fitting groove. This helps prevent the mounting shaft body with multiple surface steps from tilting and overlapping with the mounting shaft bodies at different vertical positions in the storage box, causing two mounting shaft bodies to fall into the press-fitting groove simultaneously, which would prevent the device from accurately pressing the mounting shaft body into the rotor body and the bearing body, affecting the precision of the device's press-fitting operation.
