Coiling machine main shaft mechanism

The utility model provides a coiling machine main shaft mechanism, include: headstock, main shaft and bearing, be equipped with a mounting hole on the headstock, the main shaft wear to locate in the mounting hole of headstock and through the rotatable setting of bearing on the headstock, the bearing sets up respectively at the both ends of the mounting hole of headstock and then end bearing and back end bearing before forming respectively, preceding end bearing is the same with the bearing quantity of back end bearing, and the free end is not limited and then form in the outer lane of the bearing of one end on axial direction at least. So setting up and making the main shaft more even on the atress around, for high -speed operation provides the basis, simultaneously, the outer lane of bearing is free state on axial direction, can effectively eliminate the bearing and produce the spare part expend with heat and contract with cold who generates heat and lead to the fact in high -speed operation, the frequency t
