Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

Referring to fig. 1 to 4, the composite riveting device for the upper cover of the gas meter mainly comprises a pressure cylinder 1 which is vertically arranged downwards, the pressure cylinder 1 is usually an air cylinder or a hydraulic cylinder and is mainly used for improving riveting pressure, a first template 2 is fixedly arranged at the telescopic end of the pressure cylinder 1, a second template 3 is arranged under the first template 2, as shown in the figure, the second template 3 is connected with the first template 2 through an elastic connecting piece 4, a bottom plate riveting head 5 which is vertically arranged downwards is arranged at the bottom of the second template 3, the bottom plate riveting head 5 is used for riveting the bottom plate of the gas meter with the upper cover, a shaft sleeve riveting assembly 6 which is vertically arranged downwards is arranged on the first template 2, a through hole 30 through which the shaft sleeve riveting assembly 6 passes is arranged on the second template 3, and the shaft sleeve riveting assembly 6 is used for riveting the shaft sleeve of the gas meter with the upper cover.

Referring to fig. 5 and 6, in the present application, the upper cover riveting specifically refers to riveting between the bottom plate 80 and the upper cover 8, and riveting between the shaft sleeve 81 and the upper cover 8, because there is a height difference between the two types of riveting, in order to adapt to the height difference, the elastic connecting member 4 is adopted for connection, and the height difference between the bottom plate riveting head 5 and the end of the shaft sleeve riveting component 6 needs to be designed in cooperation with the elastic connecting member 4 to ensure that the riveting depth and the riveting pressure are adapted to the required value of the riveting object, in addition, the number of the bottom plate riveting heads 5 is adapted to the point positions of the bottom plate 80 that need to be riveted, in this embodiment, there are three bottom plate riveting heads 5, and the shaft sleeve riveting component 6 is of a single-head structure.
