The blocking buckle 13 is connected to the surface of the rolling assembly sleeve 12 through threads. When tightened, the surface of the blocking buckle 13 contacts the surface of the outer plate 14 to prevent the rolling assembly from falling out of the rolling assembly sleeve 12.

[0024] Preferably, the rolling assembly includes an outer plate 14, a gear plate 27, and a fixed ring 23, wherein the outer plate 14 and the fixed ring 23 are fixedly connected, three fixed rods 24 are fixedly installed on the surface of the fixed ring 23, a bearing shaft 25 is fixedly installed at the end of each fixed rod 24, a bearing 26 is fixedly installed on the surface of each bearing shaft 25, the gear plate 27 is rollingly connected to each bearing 26, three arc-shaped openings 18 are opened on the gear plate 27, and the gear plate 27 is limited in rotation position by three bearings 26.

[0025] Preferably, three roller rails 15 are fixedly installed on the surface of the outer plate 14, and a rail sleeve 30 is slidably connected to the surface of each roller rail 15. A roller shaft 17 is fixedly connected to the outer surface of the rail sleeve 30, and a roller 16 is rotatably connected to the roller shaft 17. A sleeve fixing shaft 31 is fixedly installed on the surface of the rail sleeve 30, and the sleeve fixing shaft 31 is slidably connected to the corresponding arc-shaped opening 18. When the gear plate 27 rotates, the multiple arc-shaped openings 18 opened by the gear plate 27 also rotate accordingly, and at the same time drive the sleeve fixing shaft 31 to slide on the surface of the arc-shaped opening 18, and the rail sleeve 30 begins to slide on the surface of the roller rail 15 due to the movement of the sleeve fixing shaft 31, thereby changing the distance of the rail sleeve 30 from the center of the circle, and driving the roller shaft 17 and the roller 16 to move on the roller rail 15, so that the distance between the three rollers 16 and the center of the gear plate 27 can be adjusted at the same time.

When the adjustment gear 22 is rotated, the gear plate 27 meshing with the adjustment gear 22 will also rotate, thereby adjusting the distance between the roller 16 and the center of the circle. After the distance between the roller 16 and the center of the circle is adjusted, the two blocks 29 are rotated so that one end of the block 29 is stuck between the serrations of the adjustment gear 22, so that the adjustment gear 22 can be stuck and cannot be rotated.

[0028] Preferably, an anti-slip strip is provided at the bottom end of the base plate 1. The material of the anti-slip strip is rubber. The friction between the anti-slip strip and the ground is relatively large, which can effectively prevent the base plate 1 from moving randomly, so as to improve the stability during the spline shaft processing.

[0029] In the utility model, when in use, first clamp the spline shaft to be processed in the three-jaw chuck 10, then place the other end of the spline shaft to be processed in the center of the rolling assembly, rotate the adjustment gear 22, and the gear plate 27 meshing with the adjustment gear 22 will also rotate, the arc-shaped opening 18 on the gear plate 27 drives the sleeve fixed shaft 31 and the sleeve 30 to move, and the sleeve 30 drives the roller shaft 17 to slide on the surface of the roller slide rail 15, so as to adjust the distance between the multiple rollers 16 and the center of the circle. When the requirements are met, the two clamping blocks 29 can be rotated to make the adjustment gear 22 clamp. The clamping block 29 is fixed so that it cannot rotate, and the clamping rod 21 is used to fix the clamping block 29 so that the clamping block 29 cannot rotate, and the distance between each roller 16 in the rolling assembly and the center of the circle is determined, and the adjusted rolling assembly is placed in the rolling assembly sleeve 12, and the motor 7 is turned on to rotate the three-jaw chuck 10, and then the slide plate 4 is pushed to make the spline shaft to be processed penetrate into the rolling assembly, and the spline shaft is rolled by the roller 16.
