DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the implementation regulations described are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figure 1-6 The utility model provides a motor rotor processing fixture: it includes a fixture base 1 and a central clamping mechanism 3, the outer surface of the fixture base 1 is fixedly connected with a fixture shell 2, the top surface of the fixture base 1 is provided with the central clamping mechanism 3, and the bottom surface of the fixture base 1 is provided with a synchronous control mechanism 4.

[0022] Furthermore, the central clamping mechanism 3 includes a centering cylinder 301, a limiting groove 302, a sliding block 303, a clamping claw tooth 304, a bearing 305 and a screw 306. The outer surface of the centering cylinder 301 is provided with a limiting groove 302, the inner surface of the limiting groove 302 is slidably connected with the sliding block 303, the outer surface of the sliding block 303 is fixedly connected with the clamping claw tooth 304, the bottom surface of the sliding block 303 is fixedly connected with the bearing 305, and the bottom surface of the bearing 305 is rotatably connected with the screw 306. Through the arrangement of the centering cylinder 301, the limiting groove 302, the sliding block 303, the clamping claw teeth 304, the bearing 305 and the screw 306, during use, the electronic rotor is inserted into the centering cylinder 301, and the sliding block 303 can move in the vertical direction on the screw 306. Since the screw 306 is placed at an angle, when the sliding block 303 moves downward, it will extend outward from the centering cylinder 301, and when it moves upward, it will be retracted. The limiting groove 302 is used to limit the moving path of the sliding block 303 to prevent it from rotating.

[0023] Furthermore, the number of the limiting grooves 302 is three and they are distributed in an annular manner, the screw rod 306 is placed at an angle, and the annularly distributed limiting grooves 302 are installed with multiple sets of sliding blocks 303 and clamping claw teeth 304 to increase the clamping stability.

[0024] Furthermore, the inner surface of the bearing 305 is fixedly connected to the screw rod 306 , and the screw rod 306 passes through the fixture base 1 . The bearing 305 allows the screw rod 306 to rotate but does not drive the sliding block 303 to rotate.

[0025] Furthermore, the synchronous control mechanism 4 includes a support frame 401, a limiting hole 402, a driven gear 403, a driving gear 404 and a knob 405. The bottom surface of the clamp base 1 is fixedly connected to the support frame 401, the outer surface of the support frame 401 is provided with a limiting hole 402, the inner surface of the support frame 401 is rotatably connected to the driving gear 404, the bottom surface of the clamp base 1 is rotatably connected to the driving gear 404, and the outer surface of the driving gear 404 is fixedly connected to the knob 405. The gear 404 and the knob 405 are arranged such that during use, the driving gear 404 is rotated by the knob 405, and the driving gear 404 engages with the driven gear 403 to drive the synchronous rotation, and the rotation directions of the three driven gears 403 are the same. The driven gear 403 is supported at the bottom of the clamp base 1 by the support frame 401. When the driven gear 403 rotates, due to the threaded connection between it and the screw rod 306, it can drive the screw rod 306 to move up and down, thereby controlling the central clamping mechanism 3. When the screw rod 306 moves downward, it will pass through the limiting hole 402 on the support frame 401.

[0026] Furthermore, the number of the support frames 401 is three and they are symmetrically distributed, the limiting holes 402 penetrate the support frames 401 , and the multiple groups of support frames 401 are installed with multiple groups of driving gears 404 for controlling the screw rod 306 .

[0027] Furthermore, the driving gear 404 is meshed with the driven gear 403 , and the driven gear 403 is threadedly connected with the screw rod 306 . The driving gear 404 and the driven gear 403 are meshed to drive synchronous rotation, so that the three screw rods 306 move synchronously.

[0028] Working principle: A motor rotor processing fixture. During use, the electronic rotor is inserted into the centering cylinder 301, and the sliding block 303 can move in the vertical direction on the screw rod 306. Since the screw rod 306 is placed at an angle, when the sliding block 303 moves downward, it will extend out of the centering cylinder 301, and when it moves upward, it will be retracted. The limiting groove 302 is used to limit the movement path of the sliding block 303 to prevent it from rotating. The driving gear 404 is rotated by the knob 405, and the driving gear 404 is meshed with the driven gear 403 to drive synchronous rotation, and the rotation directions of the three driven gears 403 are the same. The driven gear 403 is supported at the bottom of the fixture base 1 by the support frame 401. When the driven gear 403 rotates, it can drive the screw rod 306 to move up and down due to its threaded connection with the screw rod 306, thereby controlling the central clamping mechanism 3. When the screw rod 306 moves downward, it will pass through the limiting hole 402 on the support frame 401, thus completing a motor rotor processing fixture.

[0029] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the implementation rules without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
