Fixture for automatically machining aero-engine blade

Abstract

The invention discloses a clamp for automatically machining aero-engine blades, which comprises a bottom plate, a base and a tailstock which are respectively arranged at the two ends of the upper side of the bottom plate, a tail ejection piece arranged at the upper end of the tailstock, a 3R base arranged at the upper end of the base, and a 3R positioning piece fixedly connected to one side of the 3R base, the other side of the 3R positioning sheet is sequentially connected with a flat plate, a concave plate, an L-shaped plate, a chuck mounting frame and a chuck mounted on the surface of the chuck mounting frame; the chuck mounting frame rotates around the Z axis, moves along the X axis and the Y axis, is in positioning connection with the L plate through bolts, rotates around the Y axis, moves along the Z axis and the X axis, is in positioning connection with the concave plate through bolts, rotates around the X axis, moves along the Z axis and the Y axis, and is in positioning connection with the flat plate through bolts, so that the adjustment of six degrees of freedom of the chuck is realized; the positions of the chucks can be conveniently adjusted according to the clamping states of the blades, so that the clamping states of all the blades are completely consistent, and stable automatic machining is guaranteed.

Description

technical field [0001] The invention relates to the field of aero-engine blade processing, in particular to a fixture for automatic processing of aero-engine blades. Background technique [0002] Aero-engine is a highly complex and sophisticated thermal machine. As the heart of an aircraft, it is not only the driving force for aircraft flight, but also an important driving force for the development of aviation. Every important change in the history of human aviation is related to the technological progress of aero-engines. It is inseparable, because the aero-engine blade processing equipment is very expensive, and the depreciation of the machine tool is lost every second, so it must be run 24 hours to be fully and effectively used for production, and the night is the human sleep biological clock time, on the one hand, workers do not They are willing to work night shifts. On the other hand, even if workers are willing to work night shifts, they are prone to make mistakes. The...
