The turning tool mechanism solves the dimensional deviation problem, and the milling cutter mechanism repairs the keyway; one end of the spindle body 1 is fixed on the three-jaw chuck 4.

[0030] Specifically, the motor-assisted support mechanism includes a base plate 51, a drive component 52, a support rod 53, a sleeve 54, a second elastic element 55, and a rotating column 56. The drive component 52 is a conventional hydraulic push rod. The base plate 51 is fixed on the output end of the drive component 52, located directly below the shaft 1. The sleeves 54 are fixed at the four corners of the base plate 51. The second elastic element 55 is a spring, with one end fixed inside the sleeve 54 and the other end fixed to the bottom of the support rod 53.

The rotating column 56 is rotatably connected to the support rods 53 at both ends and can fit against the outer wall of the shaft 1. The motor drives the reducer to rotate the spindle of the three-jaw chuck. The drive component of the auxiliary support mechanism adjusts the height of the base plate. The support rods contact the shaft through the rotating column, providing stable support. The repair mechanism processes the surface of the shaft. The support mechanism can adapt to shafts of different diameters, ensuring shaft stability during the repair process, avoiding processing errors caused by vibration, and improving repair accuracy and efficiency.

The surface of the shaft is cleaned by a cleaning brush that automatically adheres to the shaft surface to remove machining debris and oil stains, preventing impurities from affecting the support of the rotating column for the shaft. This connecting assembly includes a slide rod 66, a first elastic element 67, a baffle 68, and a fixing plate 69. The slide rod 66 is symmetrically fixed on the connecting rod 62. The first elastic element 67 is a spring, which is sleeved on the slide rod 66, with one end fixed to the baffle 68 and the other end fixed to the fixing plate 69.
