[0002] During the machining of some rotor shafts, a retaining ring needs to be inserted into the bearing portion of the rotor shaft to retain the bearing. Currently, a single retaining ring is inserted into the groove of the rotor shaft by hand, and the efficiency of the operator in press-fitting the retaining ring is low.

[0003] The application number is CN201420499160.0, which discloses a ring pressing plate, a ring pressing component and a ring pressing machine. A specific implementation of the ring pressing component includes: a ring pressing plate: including two ends, at least one end is provided with a U-shaped groove penetrating the pressing plate surface, the groove edge is provided with a U-shaped groove edge for accommodating the ring, and a magnet is provided near the bottom of the U-shaped groove; a power device, connected to the ring pressing plate, so that the ring pressing plate can move vertically up and down; a guide rail passing through the ring, so that the ring slides into the U-shaped groove edge of the ring pressing plate under the action of gravity; a rotor shaft fixing seat, so that the groove of the rotor shaft is located on the path of the U-shaped groove edge of the ring pressing plate moving downward. This implementation realizes that the ring pressing plate is driven by the power device to move vertically up and down, so that the U-shaped groove edge of the ring pressing plate clamps the adsorbed ring into the groove of the rotor shaft when pressing down, and automatically loads the ring when returning to its original position, thereby improving the efficiency of the operator in pressing the ring.

[0004] The ring pressing plate, retaining ring pressing component and retaining ring pressing machine disclosed in the above document have the following defects: when processing the retaining ring, the retaining ring needs to be fixed and used in conjunction with the pressing machine. When the processing size requirements of the retaining ring are different, different clamps need to be adapted according to the size of the workpiece, which greatly reduces the flexibility of the pressing machine.

[0005] It can be seen from this that the existing ring pressing plates, retaining ring pressing components and retaining ring pressing machines do not have the function of fixed fitting and pressing for retaining rings of different sizes. It is necessary to improve the existing deficiencies and provide a function of fixed fitting and pressing for retaining rings of different sizes. Utility Model Content
