The pre-tightening force is adjusted to ensure that when the roller 7 is placed on the V-shaped iron 6, the pressure of the roller 7 on the V-shaped iron 6 cannot cause the end cover 532 to move downwards.

Then adjusting the axial lead of the roller: placing the roller 7 on the V-shaped iron 6, and carrying out self-centering clamping on the roller 7 by the V-shaped groove 61; the axial lead of the roller 7 is coincided with the axial lead of a bearing positioned in the bearing press-in mechanism through the adjustment of the transverse fine adjustment mechanism and the vertical fine adjustment mechanism, the position of the transverse moving plate is locked through the transverse fine adjustment nut, and the position of the supporting plate is locked through the vertical fine adjustment nut.

If the axial lead of the roller 7 is higher than the axial lead of the bearing due to operation errors in operation, when the bearing presses the roller 7 into the roller 7, the pressure of the roller 7 pressing the V-shaped iron 6 is larger than the pre-tightening force of the spring 54, the V-shaped iron 6 presses the end cover 532 to move downwards and presses the spring 54 to compress, and therefore the roller 7 is prevented from rigidly pressing the V-shaped iron 6. Can make the high elastic tuning of roller 7 in order to adapt to the height of bearing when roller 7 is impressed to the bearing through the elastic buffer portion, and then reduce the rigidity friction, guarantee that the bearing is accurate to impress roller 7.
