Device and method for large-diameter ring opening end face profile machining

The invention provides a device and method for large-diameter ring opening end face profile machining. The device comprises a moving/fixing mechanism used for carrying the whole device to move or be fixed at the top end of a to-be-machined seat ring. A leveling mechanism capable of leveling is mounted at the top of the moving/fixing mechanism in a supporting manner; the top of the leveling mechanism is provided with a double-shaft linear module mechanism used for radial and axial feeding adjustment in a carrying mode. A milling mechanism used for machining the seat ring to be machined is installed at the output end of the double-shaft linear module mechanism. Through the miniaturization design, the three-axis milling function is integrated on light-weight equipment, so that the large-diameter ring opening end face profile machining is more convenient and faster, and the machining period and cost are reduced while the machining precision is guaranteed. 本发明提供了一种用于大口径环口端面面型加工的装置及方法，包括用于搭载整个装置在待加工座环顶端进行移动或者固定的移动/
