The automatic volute tongue installation device 30 presses the volute tongue 1 to be assembled downwards, and assembles the buckle of the volute tongue 1 to be assembled with the hook of the bottom shell 2 to be assembled.

Specifically, during assembly, the automatic volute tongue installation device 30, driven by the robot 40, assembles the assembly surface of the volute tongue 1 with the hook and the assembly surface of the bottom shell 2 with the buckle, so that the hook is firmly hung on an assembly surface of the bottom shell 2 to be assembled. Then, with the edge of the assembly surface of the bottom shell 2 to be assembled as the axis, the automatic installation device 30 of the volute tongue to be assembled pushes the volute tongue 1 to be assembled upward and/or forward under the action of the robot 40. At this time, the elastic structure of the second clamp 303 realizes the flexible conversion of the distance between the first clamp 302 and the second clamp 303 (that is, the distance between the first clamp 302 and the second clamp 303 increases and/or decreases), so that the L-shaped assembly surface of the volute tongue 1 to be assembled expands upward and/or forward. At this time, the automatic installation device 30 of the volute tongue presses the volute tongue 1 to be assembled downward, so that the assembly surface of the volute tongue 1 to be assembled with the buckle can be accurately assembled with the other assembly surface of the bottom shell 2 to be assembled, so that the buckle of the volute tongue 1 to be assembled is firmly stuck on the hook of the bottom shell 2 to be assembled, thereby completing the assembly between the volute tongue 1 to be assembled and the bottom shell 2 to be assembled.
