[0030] See also Figure 1-4 The utility model provides a technical solution: an automatic assembly device for a three-dimensional transformer core, comprising an iron core 1 and a base plate 2; three translation mechanisms 3 are evenly installed on the top surface of the base plate 2 along the circumferential direction, and a support mounting plate 302 that slides radially is provided on the top of the translation mechanism 3; a rotating mechanism 4 can be horizontally rotatably installed on the top surface of the support mounting plate 302, a fixed support frame 402 is fixed to the top of the side wall of the rotating mechanism 4, and a sliding support frame 403 that can move vertically is provided on the lower side of the fixed support frame 402; a lifting mechanism 5 is arranged at the center position of the three translation mechanisms 3, and the lifting mechanism 5 is provided with a support plate 504 that moves vertically.

[0031] In summary, the iron core 1 is a frame-shaped structure. When assembling the iron core, the rotating mechanism 4 rotates horizontally relative to the translation mechanism 3, so that the fixed support frame 402 and the sliding support frame 403 face outward, so that the iron core 1 can be hung on the fixed support frame 402, and then the sliding support frame 403 moves downward to firmly support the iron core. Then the rotating mechanism 4 rotates horizontally again, so that the iron core 1 faces the center direction of the base plate 2. The three supporting mounting plates 302 carry the rotating mechanism 4 to slide as a whole toward the center direction of the base plate 2, so that the three groups of iron cores 1 can complete the horizontal assembly. Then the support plate 504 of the lifting mechanism 5 moves upward, so that the three groups of iron cores 1 are vertically aligned, and finally the assembled iron core 1 is clamped and transferred by the lifting equipment.

[0032] The translation mechanism 3 includes a frame 301 whose bottom is fixed to the top surface of the bottom plate 2, a sliding module 306 whose guide rail is radially fixed to the top surface of the frame 301 and whose slider is fixed to the bottom surface of the support mounting plate 302, and a power mechanism for driving the support mounting plate 302 to slide under the guidance of the sliding module 306. Specifically, the power mechanism is that a screw rod 305 parallel to the sliding rail of the sliding module 306 is rotatably installed in the inner cavity of the frame 301, a threaded sleeve 304 is threadedly mounted on the screw rod 305, and the threaded sleeve 304 is fixedly connected to the support mounting plate 302, a servo motor 308 is fixed in the middle of the inner cavity of the frame 301, and a synchronous belt 307 is rotatably connected between the power output shaft of the servo motor 308 and one end of the screw rod 305. That is, the servo motor 308 drives the screw rod 305 to rotate through the synchronous belt 307, and the rotating screw rod 305 drives the support mounting plate 302 to slide horizontally through the threaded sleeve 304.

[0033] A slewing bearing 303 is provided on the top surface of the support mounting plate 302.

That is, the servo motor 409 drives the gear 410 to rotate, and since the outer teeth of the slewing bearing 303 are fixed to the supporting mounting plate 302, the rotating mechanism 4 is rotated horizontally as a whole. The extension and contraction of the piston rod of the telescopic cylinder 407 drives the sliding support frame 403 to move vertically.

[0034] The lifting mechanism 5 includes a fixed plate 501 whose outer edge is fixed to the frame 301, a worm gear lift 503 disposed in the middle of the fixed plate 501 and whose top end of the lifting structure is fixed to the center of the bottom surface of the support plate 504, and a servo motor 3 502 fixed to the top surface of the fixed plate 501 and connected to the worm gear lift 503. The servo motor 3 502 drives the worm gear lift 503 to operate, so as to realize the lifting movement of the support plate 504.

[0035] In order to ensure that the support plate 504 can be lifted and lowered smoothly, a plurality of guide shafts 506 are vertically fixed to the outer edge of the bottom surface of the support plate 504 , and a guide sleeve 505 which is slidably sleeved and matched with the guide shaft 506 is fixedly sleeved on the fixed plate 501 .

The frame 301 is covered with a shell 311, and the two sides of the support mounting plate 302 are respectively connected to the shell 311 with an accordion shield 1 312. The main frame 401 is covered with a protective cover 411. A support plate 507 parallel to the fixed plate 501 is fixed to the top of the inner end of the frame 301, and an accordion shield 2 508 is set on the outer periphery of the top of the guide shaft 506. The top and bottom ends of the accordion shield 2 508 are respectively fixed to the bottom surface of the support plate 504 and the top surface of the support plate 507.

[0037] The inner cavity of the frame 301 is vertically provided with a bracket 309 whose top is fixedly connected to the support mounting plate 302, and a drag chain 310 is connected between the bottom end of the bracket 309 and the bottom of the inner cavity of the frame 301. The drag chain 310 is used to pull the energy supply pipeline of the equipment on the rotating mechanism 4 to avoid the pipeline being messy and entangled.
