Detailed Description

The technical solution of the present invention will be described clearly and completely with reference to the accompanying drawings, and obviously, the described embodiments are some, but not all embodiments of the present invention. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

In the description of the present invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description and simplicity of description, but do not indicate or imply that the device or element being referred to must have a particular orientation, be constructed and operated in a particular orientation, and thus, should not be construed as limiting the present invention.

In the description of the present invention, it should be noted that, unless otherwise explicitly specified or limited, the terms "mounted," "connected," and "connected" are to be construed broadly, e.g., as meaning either a fixed connection, a removable connection, or an integral connection; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meanings of the above terms in the present invention can be understood in specific cases to those skilled in the art.

As shown in fig. 1 to 3, the present embodiment provides a quick-change punch device based on the prior art, which includes: the punch base 1, the drive collar 3, the three pawls 4, and the punch 5, and the above-mentioned structures will be described in detail one by one next. Firstly, a punch base 1 is introduced, as shown in fig. 5, a counter bore is arranged at one end of the punch base 1, three through grooves 11 are uniformly arranged on the side surfaces of the punch base 1, and the through grooves 11 are communicated with the counter bore and form an included angle of 17 degrees. One section of the three pawls 4 is respectively installed in the three through grooves 11, as shown in fig. 6, the structure of one of the three pawls 4 is schematically shown, the other section of the three pawls 4 is installed in the counter bore, and the three pawls 4 are provided with external threads 41 on the outer sides of the three through grooves 11. As shown in fig. 4, the driving retainer ring 3 is provided with internal threads 32 on the inner side of the driving retainer ring 3, the driving retainer ring 3 is sleeved on the punch base 1 and is in threaded fit with the three pawls 4 on the outer sides of the three through grooves 11, the punch 5 is inserted into the counterbore, one end of the punch is in contact with the bottom of the counterbore, and the other section of the inner side of the three pawls 4 in the counterbore is in contact with the side surface of the punch 5.
