The outer shape of the turntable 25 is a hollow T-shape, and the left part of the turntable 25 is provided with three slide grooves 26 in a circular array.

[0027] By starting the motor 1 21, the rotating rod 22 is driven to rotate, the rotating rod 22 drives the worm 23 to rotate, so that the worm 23 is engaged with the worm wheel 24, the worm wheel 24 drives the rotating disk 25 to rotate, and the rotating disk 25 drives the chute 26 to rotate synchronously.

[0028] like Figure 2 、 Figure 3 As shown, the inner wall of the sliding groove 26 is slidably connected to a slider 28 , the left end of the slider 28 is fixedly connected to a claw 27 , and the outer wall of the claw 27 is slidably connected to the inner wall of the fixing seat 1 .

[0029] When the turntable 25 drives the slide 26 to rotate, since the slide 26 has an inclination, when the slide 26 rotates, it drives the slider 28 to slide on the outer wall of the slide 26, and the slider 28 drives the claw 27 to slide on the inner wall of the fixed seat 1 synchronously, so that the claw 27 approaches the outer wall of the coupling 4 and clamps the outer wall of the coupling 4, thereby completing the fixation of the coupling 4 and achieving a fixing effect.

[0030] like Figure 2 、 Figure 5 As shown, the inner cavity of the mounting box 31 is fixedly connected to the motor 2 32, the output end of the motor 2 32 is fixedly connected to the threaded rod 33, the outer wall of the threaded rod 33 is rotatably connected to the inner wall of the mounting box 31, the outer wall of the threaded rod 33 is rotatably connected to the fixing column 34, and the right end of the fixing column 34 is fixedly connected to the left end of the fixing seat 1.

[0031] By starting the second motor 32 , the second motor 32 drives the threaded rod 33 to rotate, so that the movable block 37 moves on the threaded portion of the outer wall of the threaded rod 33 .

[0032] like Figure 2 、 Figure 5 As shown, the right part of the inner cavity of the fixed column 34 is fixedly connected to a fixed block 1 35, the inner wall of the fixed block 1 35 is rotatably connected to the outer wall of the threaded rod 33, the outer wall of the fixed block 1 35 is rotatably connected to a movable rod 1 351, one end of the movable rod 1 351 is rotatably connected to an anti-slip pad 38, the outer wall of the anti-slip pad 38 overlaps the inner wall of the coupling 4, the left part of the inner cavity of the fixed column 34 is fixedly connected to a fixed block 2 36, the inner wall of the fixed block 2 36 is rotatably connected to the outer wall of the threaded rod 33, the outer wall of the fixed block 2 36 is rotatably connected to a movable rod 2 361, one end of the movable rod 2 361 is rotatably connected to the outer wall of the anti-slip pad 38, the left part of the threaded rod 33 is threadedly connected to a movable block 37, the outer wall of the movable block 37 is slidably connected to the inner cavity of the fixed column 34, the outer wall of the movable block 37 is rotatably connected to a movable rod 3 371, one end of the movable rod 3 371 is rotatably connected to the outer wall of the anti-slip pad 38.

[0033] When the movable block 37 moves, it drives the movable rod three 371 to rotate synchronously, and the movable rod three 371 drives the anti-slip pad 38 to rise upward. During the upward rising process of the anti-slip pad 38, it drives the movable rod two 361 to rotate. At the same time, the anti-slip pad 38 drives the movable rod one 351 to rotate, so that the outer wall of the anti-slip pad 38 is pressed against the axial hole of the coupling 4, and the coupling 4 is preliminarily fixed, which facilitates the subsequent fixation of the outer wall of the coupling 4 and has the effect of auxiliary fixation.

[0034] The working principle of the present utility model is as follows: when in use, the coupling 4 to be processed is fixed on the fixed seat 1, and the axial hole of the coupling 4 is sleeved on the anti-slip pad 38, and then the motor 2 32 is started, and the motor 2 32 drives the threaded rod 33 to rotate, so that the movable block 37 moves on the threaded part of the outer wall of the threaded rod 33, and the movable block 37 drives the movable rod 3 371 to rotate synchronously, and the movable rod 3 371 drives the anti-slip pad 38 to rise upward. During the upward rising process of the anti-slip pad 38, the movable rod 2 361 is driven to rotate, and at the same time, the anti-slip pad 38 drives the movable rod 1 351 to rotate, so that the outer wall of the anti-slip pad 38 is tightly pressed against the axial hole of the coupling 4, and the coupling 4 is preliminarily fixed, which is convenient for the subsequent fixation of the outer wall of the coupling 4, and has the effect of auxiliary fixation. , then start the motor 21, drive the rotating rod 22 to rotate, the rotating rod 22 drives the worm 23 to rotate, so that the worm 23 is meshed with the worm gear 24, and the worm gear 24 drives the turntable 25 to rotate, and the turntable 25 drives the slide 26 to rotate synchronously. Because the slide 26 has an inclination, when the slide 26 rotates, it drives the slider 28 to slide on the outer wall of the slide 26, and the slider 28 drives the claw 27 to slide synchronously on the inner wall of the fixed seat 1, so that the claw 27 is close to the outer wall of the coupling 4 and clamps the outer wall of the coupling 4, thereby completing the fixation of the coupling 4 and achieving a fixing effect. During subsequent processing, since the outer wall and the shaft hole of the coupling 4 are fixed at the same time, the stability during processing is ensured, and the shaking phenomenon of the coupling 4 during processing is avoided, thereby greatly improving the user experience.
