A large aerospace shell sawing equipment and its sawing method

Abstract

The invention discloses large aerospace shell sawing equipment and a sawing method thereof. The sawing angles for large aerospace shells are not simplex, so that a multiple-angle sawing function of asawing machine is needed. The large aerospace shell sawing equipment comprises a gantry, band saw wheels, a sawing frame, a saw band, a base, a workbench, guide chip-breaking assemblies, feeding driving assemblies, cutting direction adjusting driving assemblies, a two-axis workbench driving mechanism and a pulsation generating assembly. Each guide chip-breaking assembly comprises an oscillating guide bottom plate, an oscillating guide block, an oscillating spring, an oscillating coil and a hollow iron core, wherein the oscillating coil is wound on the hollow iron core, a suction block is arranged at the top end of the oscillating guide block, the oscillating guide block and the hollow iron core form a sliding pair, and the oscillating guide block is sleeved with the oscillating spring. Thepulsation generating assembly comprises a worm speed reducer and a pulsation generating motor. According to the large aerospace shell sawing equipment and the sawing method thereof, automatic adjusting devices enabling the sawing frame to be inclinable are designed, and the inclination angle of the sawing frame can be adjusted automatically according to sawing requirements.

Description

technical field [0001] The invention belongs to the technical field of intelligent manufacturing, and in particular relates to sawing equipment and a sawing method for large aerospace shells.
