[0027] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0028] According to the attached Figures 1-5 As shown, the embodiment of the present utility model provides an adjustable positioning device for processing the outer shell of metal products, including a base 1. A rotating mechanism 2 is arranged on the upper surface of the base 1, and the rotating mechanism 2 is used to drive the metal shell to rotate. A fixing mechanism 3 is arranged on the upper surface of the base 1, and the fixing mechanism 3 is used to fix the metal shell.

[0029] The fixing mechanism 3 includes a mounting post 301. Four mounting grooves are arranged in a circumferential array on the surface of the mounting post 301. A transmission cavity 302 corresponding to the positions of the four mounting grooves is arranged inside the mounting post 301. A rotating opening penetrating into the interior of the transmission cavity 302 is arranged on the inner wall of the mounting groove. A threaded rod 303 is rotatably connected to the inner wall of the rotating opening. A threaded cylinder 304 is threadedly connected to the surface of one end of the threaded rod 303 located inside the mounting groove. A pressing plate 305 is fixedly connected to the end of the threaded cylinder 304 away from the threaded rod 303. A motor 306 and a controller 307 are respectively embedded in the interior of the mounting post 301. The output shaft of the motor 306 extends into the interior of the transmission cavity 302 and is fixedly connected to a driving bevel gear 308. A driven bevel gear 309 is fixedly connected to one end of the threaded rod 303 located inside the transmission cavity 302.

[0030] The driving bevel gear 308 and the driven bevel gear 309 are meshed with each other. The output shaft of the motor 306 is respectively in transmission connection with the four threaded rods 303 through the driving bevel gear 308 and the driven bevel gear 309. Guide sliders are arranged on both the upper surface and the lower surface of the threaded cylinder 304. Guide chutes for the guide sliders to slide are arranged on both the inner top wall and the inner bottom wall of the mounting groove. Under the guiding action of the guide sliders, the threaded cylinder 304 can drive the pressing plate 305 to move directionally through the rotation of the threaded rod 303.

[0031] It should be noted that through the setting of the fixing mechanism 3, the metal outer shell is sleeved on the mounting column 301. Under the operation of the motor 306, the active bevel gear 308 and the driven bevel gear 309 can drive the four threaded rods 303 to rotate simultaneously. The four threaded barrels 304 drive the four pressing plates 305 to be pressed against the inner wall of the metal outer shell in an outward expanding form under the rotation of the four threaded rods 303, so that the metal outer shells of different sizes can be fixed quickly, and there will be no processing dead corners on the outer side of the metal outer shell.

When the pressure reaches the value required to fix the metal outer shell, the pressure sensor 5 controls the motor 306 to stop running through the controller 307, avoiding damage to the metal outer shell caused by excessive pressure.

[0035] The bevel gear 205 meshes with the bevel gear ring 203, and the operation crank 204 is drivingly connected to the connecting plate 201 through the bevel gear 205 and the bevel gear ring 203.

[0036] It should be noted that through the setting of the rotating mechanism 2, the operation crank 204 can be rotated to drive the connecting plate 201 to rotate through the bevel gear 205 and the bevel gear ring 203, so as to adjust the processing angle of the metal outer shell thereon.

[0037] Thread grooves are formed on the surface of the operation crank 204, and a fixing nut 6 is threadedly connected to the surface of the operation crank 204 through the thread grooves.

[0038] It should be noted that through the setting of the fixing nut 6, the fixing nut 6 is rotated through the thread groove to move on the surface of the operating crank 204 until the fixing nut 6 abuts against the surface of the base 1, so as to fix the operating crank 204 and prevent it from rotating independently.
