The spindle of the axial synchronous feed servo motor 301 rotates, and the axial feed screw 306 is driven to move up and down by an axial synchronous feed decelerator 302 mounted on an axial synchronous feed decelerator mounting plate 303 and a screw lifter 304 mounted on a screw lifter mounting plate 305. The middle part of the axial feed screw 306 is connected with the middle plate side link 311 through the axial feed screw and the lifting link bearing 308, the middle plate side link 311 is fixed on the middle lifting plate 101 through the middle plate side link connecting shaft 312 and the middle plate side link connecting shaft nut 313, so that the axial movement of the lifting screw drives the axial movement of the middle lifting plate 101 on the upright post 310, and the axial feeding of the special-shaped external spinning wheel is realized.
The axial feed screw 306 is secured to the inner race of the axial feed screw mounting bearing 315 by a first axial feed screw mounting bearing end cap 316 and a first axial feed screw mounting bearing securing bolt 317, the axial feed screw mounting bearing 315 is secured to the screw three-way linkage outer disc 204 by a second axial feed screw mounting bearing end cap 318, a second axial feed screw mounting bearing securing bolt 319, and the screw three-way linkage outer disc 204 is secured to the intermediate plate link 311 by an inner wheel mount 314, as shown in fig. 12. Thereby, when the first axial feed screw mounting bearing fixing bolt 317 moves axially, the outer disc 204 of the spiral three-way linkage mechanism is driven to move axially, and further axial movement of the special-shaped inner rotary wheel is realized.
Through the two hard connections, the lifting screw axially feeds and synchronously drives the middle lifting plate 101 and the outer disc 204 of the spiral three-way linkage mechanism to axially move, so that synchronous radial feeding of the inner rotating wheel and the outer rotating wheel is realized.
