They are only for the convenience of describing this patent and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, they should not be understood as limitations on this patent.

[0019] In the description of this patent, it should be noted that, unless otherwise expressly specified or limited, the terms "installed," "connected," "connected," and "set" should be understood in a broad sense. For example, they can refer to fixed connection or set, detachable connection or set, or integral connection or set. Those skilled in the art will understand the specific meanings of the above terms in this patent based on the specific circumstances.

[0020] The present embodiment describes a bearing outer ring punching and positioning device, which includes a base 1, an upper cover 3, a pressing cover 4, and a fixing bolt 5, wherein the base 1 is cylindrical, one end of the base 1 is sealed to form an end plate, a raised connecting column 2 is provided on the outer side of the end plate, a first sleeve ring 6 is extended from the edge of the end plate, and a positioning column 7 is extended from the inner center of the end plate; the bearing outer ring 8 is sleeved on the base 1, one end of the bearing outer ring 8 after sleeved is in contact with the first sleeve ring 6, and the other end is provided with an upper cover 3, a pressing cover 4 is provided on the outer side of the upper cover 3, and the fixing bolt 5 passes through the upper cover 3 and the pressing cover 4 and is connected to the positioning column 7.
