[0016] In order to enable those skilled in the art to better understand the technical solution of the utility model, the preferred implementation scheme of the utility model is described below in conjunction with specific embodiments, but it should be understood that these descriptions are only for further illustrating the features and advantages of the utility model, rather than limiting the patent requirements of the utility model. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the utility model.

[0017] The utility model is further described below in conjunction with the accompanying drawings and preferred embodiments.

[0018] Example 1

[0019] See also Figures 1 to 4 As shown, a cylinder positioning ring riveting device involved in this embodiment includes a bottom plate 1 and a top plate 2 arranged above the bottom plate, a side plate 3 is connected between the top plate 2 and the bottom plate 1, a servo pole 4 is provided on the top plate 2, the servo pole 4 has a pressure rod that moves vertically up and down, a positioning column 5 erected on the bottom plate 1 is provided directly below the pressure rod, and a closed ring-shaped flared portion 6 is provided at the connection between the positioning column 5 and the bottom plate 1; an ejection element 7 for lifting the workpiece is provided on the bottom plate 1.

[0020] Furthermore, the ejection element 7 is an elastic ring with a portion buried in the bottom plate 1 and another portion protruding from the upper end surface of the bottom plate 1 , and the elastic ring is a rubber elastic ring.

[0021] Furthermore, the elastic ring and the positioning column 5 are arranged coaxially.

[0022] Furthermore, the positioning column 5 and the pressure rod are coaxially arranged.

[0023] In this embodiment, the cylinder body 100 and the positioning ring 200 are first mounted on the positioning column 5, and the connecting ring piece 101 is inserted into the flared opening 201. Then, the servo rod 4 is operated to move the upper pressure rod downward to press the cylinder body 100 and the positioning ring 200. Due to the obstruction of the flared opening 6, the connecting ring piece 101 is deformed and expanded outward, so that the positioning ring 200 is connected to the cylinder body 100. During this period, the ejection element 7 is deformed and compressed, but when the pressure rod is reset, the ejection element 7 recovers its deformation and appropriately lifts the press-fitted cylinder body 100 and the positioning ring 200 upward, which is convenient for material removal.
