This utility model discloses a cylinder shaft clamping
cutting stabilizing device for milling the outer
diameter of a sleeve, including a frame, a slide, a slide table, a rotary chuck, a
cutting tool, and a through-rod cylinder. The cylinder shaft of the through-rod cylinder runs through the cylinder body, forming two output shafts extending out of the cylinder body. One output shaft is fixed to the slide table, while the other output shaft is in a
free state. A support rod is fixed to the end of the free output shaft of the through-rod cylinder, and a clamping cylinder is fixed to the support rod. A shaft support is provided at the end of the cylinder shaft of the clamping cylinder. This utility model drives the semi-cylindrical shaft support through the clamping cylinder to extend and fit against the free output shaft of the through-rod cylinder. The fit surface between the shaft support and the output shaft forms a constraint, limiting the axial slippage and radial runout of the output shaft, significantly reducing vibration interference during the milling of the outer
diameter of the sleeve, ensuring accurate alignment of the
cutting tool and the rotary chuck, and significantly improving key accuracy indicators such as the roundness and
surface roughness of the outer
diameter of the sleeve.
