Description

Technical Field

[0001] The utility model relates to the field of rotor punching processing, in particular to a deburring device for rotor punching of a large torque motor. Background Art

[0002] The current motor is mainly composed of a stator and a rotor, in which the rotor is formed by stacking rotor stampings. In the manufacturing process of rotor stampings, stamping is usually used to obtain rotor stampings. However, the outer edges of the rotor stampings after stamping often have burrs. Therefore, we need a device that can remove the burrs of the rotor stampings. The existing rotor stamping deburring equipment generally performs single-piece deburring, which means that the deburring process needs to be processed piece by piece, which is more cumbersome.

[0003] After searching, Chinese patent announcement number: CN219704530U discloses a rotor punching deburring device, including a workbench and a rotor punching, a deburring device for deburring the rotor punching is installed on the workbench, a base is installed below the workbench, a longitudinal slide rail is installed on the base, a longitudinal slider is connected to the longitudinal slide rail for longitudinal sliding, a connecting seat is fixed above the longitudinal slider, a fixed turntable for fixing the rotor punching is rotatably connected above the connecting seat, a longitudinal moving opening is opened on the workbench, the deburring device is located at the rear end of the longitudinal moving opening, the fixed turntable is located in the longitudinal moving opening, a plurality of vertical screws are connected above the fixed turntable, and the rotor punching is inserted into the plurality of vertical screws and locked by nuts. In the fixing of the rotor punching, the utility model inserts multiple rotor punchings into the vertical screws and locks them by nuts, then moves the fixed rotor punching longitudinally to the side of the deburring device, and removes burrs from it by the deburring device, which has high working efficiency.

In addition, the rotor punchings at the bottom layer are fitted with the movable seat, which is too inconvenient when taking materials. Therefore, a high-torque motor rotor punching deburring device is proposed to solve the above problems. Utility Model Content

[0032] Reference Figure 2 - Figure 4 The lifting assembly includes a rectangular plate 61 that can drive the top plate 63 to move stably. The rear surface of the bottom end of the rectangular plate 61 is slidably connected to the right surface of the base 4. The top of the rear surface of the rectangular plate 61 is fixedly connected with an arc-shaped connecting plate 62. The left end of the base 4 is also provided with a group of rectangular plates 61 and top plates 63 to ensure that the rotor punchings can be stably lifted up, and multiple groups of rectangular plates 61 are connected by the arc-shaped connecting plate 62. The top of the left surface of the rectangular plate 61 is fixedly connected with the top plate 63.
