The upper end of the press-fitting support 19 is provided with an annular mounting chamber 22, and the outer circle of the mounting chamber 22 penetrates the outer peripheral wall of the press-fitting support. The lower end of the press-fitting support 19 is provided with a connecting rod member 23, the lower end of the connecting rod member 23 extends in the vertical downward direction, and the outer side of the connecting rod member 23 is provided with a spiral guide groove 24.

The inner hole wall of the connecting hole 25 is provided with a semispherical guide protrusion 26, and the guide protrusion 26 is slidingly arranged in the spiral guide groove 24. When the spinning disc 20 slides up and down along the axial direction of the connecting rod member 23, the guide protrusion 26 and the spiral guide groove 24 can drive the spinning disc 20 to rotate in the circumferential direction.

[0079] The lower end of the spinning disc 20 is provided with a circular buffer ring groove 27, the longitudinal section shape of the buffer ring groove 27 is T-shaped, and the central axis of the buffer ring groove 27 coincides with the central axis of the connecting hole 25. An active pressure ring 28 is arranged in the buffer ring groove 27, the shape of the active pressure ring 28 is matched with the shape of the buffer ring groove 27, and the active pressure ring 28 can slide up and down along the axial direction of the buffer ring groove 27. A positioning groove 29 is arranged on the inner wall of the buffer ring groove 27 in the axial direction, and a positioning protrusion 30 is arranged on the outer peripheral wall of the active pressure ring 28, the positioning protrusion 30 extends into the positioning groove 29, so as to limit the circumferential rotation of the active pressure ring 28 in the buffer ring groove 27. A ring-shaped buffer gas bag 31 filled with inert gas is also arranged in the buffer ring groove 27, the upper end of the buffer gas bag 31 abuts against the inner groove wall of the upper end of the buffer ring groove 27, and the lower end of the buffer gas bag 31 is provided with a smooth metal abutting piece 32, which abuts against the upper end of the active pressure ring 28, so as to reduce the friction between the buffer gas bag 31 and the active pressure ring 28. The buffer gas bag 31 drives the lower end of the active pressure ring 28 to protrude from the slot of the buffer ring groove 27 and keep this state by pressure. The lower end of the active pressure ring 28 is provided with a rubber pressure ring 33, which abuts against the fan blade to be pressed and drives the fan blade to rotate circumferentially with the active pressure ring 28.

[0080] A connecting ring groove 34 in the shape of a circular ring is coaxially arranged on the outer peripheral wall of the spinning disc 20. The spinning drive mechanism 21 includes two spinning drive cylinders 211, which are symmetrically distributed around the connecting rod 23.

When the piston rod of the spinning drive cylinder 211 extends or retracts, the spinning drive cylinder 211 drives the spinning disc 20 to move axially by the cooperation of the connecting piece 212 and the connecting ring groove 34.

[0081] In order to ensure that the transmission shaft located inside the air compressor head can effectively drive the fan blade to rotate circumferentially when the air compressor head is running, a limiting plane is usually arranged on the outer peripheral wall of the transmission shaft, and an abutting plane is arranged on the inner hole wall of the fan blade to match with the limiting plane. Therefore, when the fan blade is directly placed above the transmission shaft inside the air compressor head by the pneumatic clamp 108, the fan blade cannot be fitted to the outside of the transmission shaft due to the fact that the limiting plane cannot be directly opposite to the abutting plane.

[0082] When the above-mentioned situation occurs, the first step is to drive the press-fitting seat 109 to move along the horizontal direction by the fan blade installation horizontal moving mechanism 107, so that the press-fitting seat 109 moves to the upper side of the air compressor head, the second step is to drive the press-fitting seat 109 to move downward by the fan blade feeding lifting mechanism 105, so that the connecting rod 23 on the press-fitting seat 109 passes through the inner hole of the fan blade and abuts against the upper end of the transmission shaft, at this time, the connecting rod 23 passing through the inner hole of the fan blade can be used to support and limit the fan blade, so that the fan blade is not easy to shake in the subsequent installation process, at the same time, the rubber compression ring 33 at the lower end of the spinning disc 20 will abut against the upper end of the fan blade, so as to further support and limit the fan blade, so that the fan blade is not easy to shake in the subsequent installation process, in addition, the rubber compression ring 33 is made of rubber material, which is soft in texture and is not easy to extrude the upper end of the fan blade to deformation, the third step is to control the piston rod of the spinning drive air cylinder 211 to extend downward, the piston rod of the spinning drive air cylinder 211 will drive the spinning disc 20 to move downward along the axial direction through the cooperation of the connecting plate 212 and the connecting ring groove 34, at the same time, the spinning disc 20 will rotate along the circumferential direction under the cooperation of the guide protrusion 26 and the spiral guide groove 24, and the spinning disc 20 will drive the fan blade to rotate along the circumferential direction through the rubber compression ring 33, when the limiting plane is not opposite to the abutting plane, the fan blade and the transmission shaft will keep the relative fixation of the axial position, so that in the process of moving the spinning disc 20 downward, the fan blade will be extruded into the buffer groove through the rubber compression ring 33, the buffer air bag 31 can provide space for the axial movement of the movable compression ring 28 through deformation in this process, the rubber compression ring 33 can also provide space for the axial movement of the movable compression ring 28 through deformation, when the limiting plane is turned to be opposite to the abutting plane, the buffer air bag 31 will drive the movable compression ring 28 and the rubber compression ring 33 to move downward through the pressure, and then the fan blade is sleeved to the outside of the transmission shaft, the fourth step is to control the piston rod of the spinning drive air cylinder 211 to retract upward, the piston rod of the spinning drive air cylinder 211 will drive the spinning disc 20 to move upward along the axial direction through the cooperation of the connecting plate 212 and the connecting ring groove 34, so as to complete the resetting of the spinning disc 20, the fifth step is to drive the press-fitting seat 109 to move by the fan blade installation horizontal moving mechanism 107 and the fan blade feeding lifting mechanism 105, so as to complete the resetting of the press-fitting seat 109.

[0083] Of course, the above is only a typical example of the present application, in addition to this, the present application can have other various specific embodiments, any technical solution formed by equivalent replacement or equivalent transformation falls within the scope of the present application.
