[0001] The utility model relates to the field of deep groove ball bearing processing, in particular to an auxiliary device for butting and installing the inner ring of a deep groove ball bearing. Background Art

[0002] Deep groove ball bearings, formerly known as radial ball bearings, are the most widely used rolling bearings. They are characterized by low friction resistance and high speed. They can be used on parts that bear radial loads or combined loads of radial and axial forces. They can also be used on parts that bear axial loads, such as small power motors, automobile and tractor gearboxes, machine tool gearboxes, general machines, tools, etc.

[0003] At present, after processing, the inner ring and outer ring of the deep groove ball bearing need to be butt-jointed and installed. Most of the existing methods clamp the inner ring with a clip and then butt-jointly install it with the outer ring. This makes it easy for the clip to rub against the inner wall of the outer ring during installation, causing certain damage to it. Utility Model Content

[0006] A spreading mechanism is provided on one side of the mounting plate, and the spreading mechanism includes a cylindrical barrel, a bearing inner ring, a motor, a rotating shaft, a movable plate, a fixed shaft and a rotating plate. A cylindrical barrel is fixedly mounted on one side of the mounting plate, a motor is fixedly mounted on one side of the inner wall of the cylindrical barrel, a rotating shaft is fixedly mounted on the output shaft of the motor, two movable plates are fixedly mounted on the outer ring of the rotating shaft, two fixed shafts are rotatably mounted on the inner wall of the cylindrical barrel, a rotating plate is fixedly mounted on one end of the two fixed shafts, the two rotating plates are respectively connected with the movable plate and the inner ring, and the rotating plate is used to spread and fix the installed bearing inner ring.

[0007] In one example, a sliding groove is provided on one side of the fixing plate, and a sliding block is slidably connected to one side of the inner wall of the sliding groove.

[0008] In one example, an arc-shaped pressure plate is fixedly mounted on one side of the slider, and the arc-shaped pressure plate fits against the outer ring of the bearing.
