[0011] Beneficial Effects

[0012] The utility model provides a cylindrical blank grinding device, which has the following beneficial effects:

[0013] The cylindrical blank grinding device is provided with a friction wheel, a friction plate, a torsion spring and an arc-shaped tilting block, and the threaded shaft is rotated to engage with the rib rod so that the grinding plate is located at the top, and the motor is started to drive the hollow disk to rotate through the transverse shaft and the torsion spring to rotate the blank.

When the surface smoothness of the blank increases, the torsion force applied to the torsion spring increases, so that the friction plate can contact the friction wheel again, and the grinding plate can grind the blank layer by layer, thus solving the problem that the initial contact force of the grinding plate on the blank is large, which easily causes damage to the blank when the blank rotates.

[0014] The cylindrical blank grinding device is provided with a threaded rod. According to the minimum diameter requirement of the blank to be ground, the threaded rod is rotated to engage with the edge rod, and the distance between the threaded rod and the top plate is adjusted, thereby changing the maximum downward movement distance of the edge rod and the grinding plate.
