Processing method and steps of transmission shaft hole of base of super-large vertical lathe

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.

Description

technical field [0001] The invention relates to a processing method for a transmission shaft hole of a base of a super-large vertical lathe, which can be applied to machine tools and equipment requiring a large-scale transmission system such as a heavy-duty vertical lathe and a heavy-duty gear hobbing machine. Background technique [0002] The super large vertical lathe base is the key component of the vertical lathe, its main function is to support and position the workbench, and transmit power through the transmission shaft gear on the base and the large ring gear on the workbench. Since the diameter of the ring gear of the heavy-duty vertical lathe can reach ten meters, the distance between the center hole of the ring gear and the gear hole of the transmission shaft can reach more than 5 meters. , in order to ensure the accuracy and life of the movement, the center distance between the two must be strictly controlled. At present, the positioning center hole of the ring g...
