[0022] When the gear is installed on the shaft body 7, the flat key 13 is retracted into the interior of the shaft body 7. After the gear is sleeved on the shaft body 7, the notch on the gear is aligned with the flat key 13, and the mounting column 14 is rotated through the protrusion 16. Under the action of the thread, the mounting column 14 moves toward the interior of the shaft body 7, thereby causing the conical block 15 to move toward the interior of the shaft body 7. During the movement of the conical block 15, the outer diameter of the contact position between the conical block 15 and the bottom of the flat key 13 gradually increases, thereby pushing the flat key 13 out of the shaft body 7, so that the shaft body 7 cooperates with the flat key 13 to fix the gear. When disassembling, rotate the mounting column 14 in the opposite direction, and then press the flat key 13 to retract the flat key 13 into the shaft body 7. In this way, the installation and disassembly of the gear is convenient. After the gear is installed on the shaft body 7, the displacement assembly drives the pressure plate 5 to move in the direction of the gear, and cooperates with the mounting plate 2 to fix the gear.

[0023] Specifically, Figure 2As shown, the rotating assembly includes a second motor 10, and the second motor 10 is fixedly connected to the right end of the mounting plate 2, the output end of the second motor 10 is fixedly connected to a driving gear 9, the top end of the driving gear 9 is meshingly connected to a driven gear 8, and the left side of the driven gear 8 is fixedly connected to the shaft body 7, the second motor 10 drives the driving gear 9 to rotate, the rotating driving gear 9 rotates the shaft body 7 through the driven gear 8, the gear installed on the shaft body 7 can be changed in position, and the processing of the gear is convenient.

[0024] Specifically, Figure 1 As shown, the displacement assembly includes a first motor 3, and the first motor 3 is fixedly connected to the left end of the base 1, the output end of the first motor 3 is fixedly connected to a threaded rod 4, and the threaded rod 4 is rotatably connected to the inside of the base 1, the outer side of the threaded rod 4 is threadedly connected to the bottom end of the pressure plate 5, and the bottom of the pressure plate 5 is slidably connected to the base 1, the first motor 3 drives the threaded rod 4 to rotate when it works, and the rotating threaded rod 4 drives the pressure plate 5 to move through the thread.

[0025] Specifically, Figure 2 As shown, a pair of mounting pins 11 are fixedly connected to the right end of the mounting plate 2, and a rack 12 is slidably connected to the outer side of the pair of mounting pins 11, and the rack 12 cooperates with the driven gear 8. The length of the mounting pin 11 is greater than the thickness of the driven gear 8. The rack 12 moves along the mounting pin 11 toward the mounting plate 2, so that the rack 12 is meshed with the driven gear 8. The driven gear 8 is fixed by the rack 12, which facilitates the rotation of the mounting column 14 and the fixing of the gear during the gear processing.

[0026] Specifically, Figure 1 and Figure 2 As shown, a pair of guide rails 6 are fixedly connected to the top of the base 1, and the bottom of the pressure plate 5 is slidably connected to the pair of guide rails 6.

[0027] Working principle: After the gear is sleeved on the shaft body 7, the notch on the gear is aligned with the flat key 13, and the mounting column 14 is rotated through the protrusion 16. Under the action of the thread, the mounting column 14 moves toward the inside of the shaft body 7, thereby causing the conical block 15 to move toward the inside of the shaft body 7. During the movement of the conical block 15, the outer diameter of the contact position between the conical block 15 and the bottom of the flat key 13 gradually increases, thereby pushing the flat key 13 out of the shaft body 7 and embedding it into the notch in the gear, so that the shaft body 7 cooperates with the flat key 13 to fix the gear, and the first motor 3 works to drive the threaded rod 4 rotates, the rotating threaded rod 4 drives the pressing plate 5 to move through the thread, and cooperates with the mounting plate 2 to fix the gear. After the gear is fixed, the gear can be processed. When the gear position is changed, the second motor 10 works to drive the driving gear 9 to rotate, and the rotating driving gear 9 rotates the shaft body 7 through the driven gear 8, so that the position of the gear installed on the shaft body 7 can be changed. After the gear processing is completed, the mounting column 14 is rotated in the opposite direction, and then the flat key 13 is pressed to retract the flat key 13 into the shaft body 7, that is, the gear can be removed from the shaft body 7.
