[0007] The utility model with the above-mentioned characteristics: the end cover is placed on the end cover placing plate, and after the shell moved to the riveting station is placed on the end cover, the driving device drives the pressing head to rivet the shell and the end cover. At this time, the end cover placing plate moves downward in the movable groove with the end cover and the shell, and the annular positioning convex edge enters the annular groove of the end cover to position the end cover. After the pressing is completed, the resetting device pushes the end cover placing plate upward to reset it, and then the annular positioning convex edge is disengaged from the annular groove of the end cover, so that the end cover and the shell after pressing are convenient to be separated from the riveting station.

[0008] A further configuration of the utility model is that the reset device includes a plug-in block provided below the end cover placement plate, the base is provided with a plug-in hole at the bottom of the movable groove corresponding to the plug-in block and coaxially penetrates through the mounting seat, the plug-in block is movably plugged into the plug-in hole, a movable cavity is provided between the end cover placement plate and the bottom of the movable groove, and the plug-in block is provided with a spring in the plug-in hole.

[0009] The utility model is further configured as follows: a first placement groove is provided at one end of the plug-in block relative to the end cover placement plate, a second placement groove is coaxially opened on the mounting seat corresponding to the first placement groove, and two ends of the spring are respectively inserted into the first placement groove and the second placement groove.

[0010] The utility model with the above characteristics: when the end cover placement plate moves downward in the movable groove, the spring is compressed, and after the pressing is completed, the spring returns to drive the end cover placement plate to move upward so that the annular positioning convex edge escapes from the end cover annular groove.

[0011] A further configuration of the utility model is that a guide device is provided between the plug-in block and the mounting seat.

[0012] A further arrangement of the utility model is: the guiding device includes a guide rod provided at one end of the plug-in block relative to the end cover placement plate, the mounting seat is coaxially provided with a guide hole corresponding to the guide rod, the guide rod is movably inserted in the guide hole, and a limit block is provided at one end of the guide rod relative to the plug-in block, the diameter of the limit block is larger than the diameter of the guide hole, and the limit block is located on the side of the mounting seat relative to the mounting groove.

[0013] The utility model with the above characteristics: the guide rod cooperates with the plug-in block for guidance, and the end cover placement plate is stuck when it moves downward.

[0014] The beneficial effect of the utility model is that the end cover placement plate is provided with a reset device, which is convenient for escaping from the riveting station after the riveting is completed.

[0015] The utility model is further described in detail below with reference to the accompanying drawings and embodiments. BRIEF DESCRIPTION OF THE DRAWINGS
