[0017] Below by embodiment, and in conjunction with the accompanying Figure 1-Figure 5 The structure is shown in the figure, and the technical solution of the utility model is further described in detail.

[0018] First embodiment: A large-scale winding machine core mold centering device includes a base 1, a head assembly 2 is fixedly provided on one end of the base 1, a slide rail 14 is installed on the other end of the base 1, a tailstock assembly 3 is slidably provided on the slide rail 14, a support assembly 4 is fixedly provided on the base 1 adjacent to the head assembly 2, a core mold assembly 5 is provided between the support assembly 4 and the tailstock assembly 3, and the core mold assembly 5 is fixed to the head assembly 2 by clamping.

[0019] Specifically, such as Figure 2 As shown, a head assembly 2 for driving the core mold assembly 5 to rotate is fixed on one end of the base 1, a slide rail 14 is installed on the other end of the base 1, and a tail stock assembly 3 for tightening the core mold assembly 5 is slidably installed on the slide rail 14. A support assembly 4 is fixed on the base 1 adjacent to the head assembly 2. The support assembly 4 adopts a V-shaped structure to locate the rotation center, so as to ensure the positioning accuracy of the core mold assembly 5 during installation.

[0020] The support assembly 4 includes a support frame 6, a V-shaped seat 7 and a universal ball 8. The support frame 6 is fixed on the base 1, the V-shaped seat 7 is fixed on the support frame 6, and the universal ball 8 is installed in the V-shaped seat 7.

[0021] Specifically, the bottom of the support frame 6 is fixedly connected to the base 1 by bolts, such as Figure 3 As shown, the V-shaped seat 7 fixes the top of the support frame 6, and universal balls 8 are installed on the two inclined inner walls and the inner bottom wall of the V-shaped seat 7. When the core mold 9 is replaced, the V-shaped seat 7 can play a supporting and positioning role. When the head assembly 2 drives the core mold assembly 5 to rotate, the universal balls 8 in the V-shaped seat 7 can reduce the resistance of the core mold assembly 5 during rotation.

[0022] The core mold assembly 5 includes a mold core 9, a transmission shaft 10, an auxiliary shaft 11 and a slot 12. The slot 12 is threadedly connected to one end of the mold core 9. A protrusion 13 matching the slot 12 is provided on one end of the transmission shaft 10. The transmission shaft 10 is engaged with the slot 12 through the protrusion 13. The other end of the transmission shaft 10 is fixedly connected to the head assembly 2 and the transmission shaft 10 is located in the V-shaped seat 7.
