Rotary pressing device for spinning shaft end cover

The invention provides a rotary pressing device for a spinning shaft end cover, and belongs to the technical field of spinning machinery. The rotary pressing device for the spinning shaft end cover comprises a swinging air cylinder, a main shaft, a bolt-action air cylinder and a rotary pressing tool, wherein a first gear is coaxially connected with the swinging air cylinder; a second gear and a third gear are coaxially arranged on a gear shaft; the first gear and the second gear are engaged; the main shaft is rotationally arranged on a supporting shaft guide sleeve, and a needle bearing is arranged between the main shaft and the supporting shaft guide sleeve; the third gear and a fourth gear are engaged; a cylinder body of the bolt-action air cylinder is fixed to the upper end of a supporting seat; the lower end of a piston rod is provided with a connecting support, and the connecting support is rotationally connected with the upper end of the main shaft; the rotary pressing tool is installed at the lower end of the main shaft through fastening screws; a hollow shaft body is clamped through a shaft body clamp. The end cover is rotationally pressed on the hollow shaft body, labor intensity of workers is greatly relieved, and the production efficiency of a spinning shaft is improved.
