Abstract
The invention relates to a processing method and steps of a transmission shaft hole in a base of a super-large vertical lathe. The technical scheme adopted by the processing method lies in that during the turning of a base, finish turning is performed at a position which is close to the excircle of the base so as to form a light band, the light band is rigidly guaranteed to be concentric with a gear ring positioning center hole, and the actual diameter of the light band is measured. When fine boring is performed on the base on a floor type boring and milling machine so as to form a transmission shaft hole, a base workpiece is horizontally placed on the fixing platform of the floor type boring and milling machine, a distance tolerance between the transmission shaft hole and the gear ring positioning center hole is controlled by rigidly controlling a distance between the center of the transmission shaft hole and the excircle of the light band. According to the processing method of the transmission shaft hole in the base of the super-large vertical lathe, simple means and steps are adopted, not only the danger of vertically processing the base of which the diameter is more than 10 meters is avoided, but also the difficult technical problem that large-scale tools are needed for positioning is solved, so that the processing cost is greatly reduced, and the precision requirements for the bases of super-large vertical lathes can be satisfied; besides, the processing needs for the bases of larger sizes can also be satisfied.
