Abstract

The invention discloses an auxiliary measuring device for automatic machining of lugs, and belongs to the technical field of aviation structural part machining. The auxiliary measuring device comprises a base, an elastic supporting device and a locking device; the elastic supporting device comprises a top disc, a knuckle bearing, a supporting rod and a spring, the top disc is connected with the supporting rod through the bearing, and the supporting rod is provided with an inner cavity for containing the spring; the locking device comprises a clamping pin I, a clamping pin II and a screw, and the screw penetrates through the clamping pin I and then is detachably connected with the clamping pin II; and a through hole for penetrating through the locking device is formed in the base in the horizontal direction, a blind hole for installing the elastic supporting device is formed in the base in the vertical direction, and the through hole and the blind hole are eccentrically arranged in a penetrating mode. Meanwhile, the invention discloses a using method of the device. The problem that in the prior art, the thickness of lugs on large frame and beam parts cannot be accurately measured is solved.

Description

technical field [0001] The invention relates to the technical field of mechanical processing of aviation structural parts, in particular to an auxiliary measuring device for automatic processing of lugs and a method for using the same, especially suitable for automatic processing of lugs on large frame and beam parts. Background technique [0002] As the most typical feature of the connection between aeronautical structural parts, lugs play an important role in coordination and positioning in the assembly process of aircraft parts. They usually appear on fatigue-critical parts such as large frames, beams, and complex joints. The processing quality has an important impact on the safety performance and service life of the aircraft. Therefore, the upper and lower surfaces of such features are usually flat, the thickness and dimensional accuracy requirements are above IT9 level, and the surface roughness requirements are also Ra1.6 and above. For such characteristics, a stable ...
