Abstract

A combined tool for spraying paint protection for a main wheel of a plane is composed of an unthreaded hole protective plug, a protective sleeve, a protective cover, a protective conical sleeve, a threaded hole protective plug and a protective plate. The unthreaded hole protective plug is used for realizing spraying paint protection for a tensioning bolt hole. The protective sleeve is used for realizing spraying paint protection for a transmission block installation part of the main wheel of the plane. The protective cover is used for realizing spraying paint protection for a large end hole and a small end hole of a semi-wheel hub center hub part of the main wheel of the plane. The protective conical sleeve is used for realizing spraying paint protection for a semi-wheel hub bearing cup of the main wheel of the plane. The threaded hole protective plug is used for carrying out spraying paint protection on a pressure relief valve installation threaded hole and a valve rod installation threaded hole of the main wheel of the plane. The protective plate is used for carrying out spraying paint protection on a semi-wheel hub butt joint part of the main wheel of the plane. The combined tool for spraying paint protection for the main wheel of the plane does not damage the completeness of a paint layer and has the characteristics of being convenient to mount and dismount.

Description

technical field [0001] The invention relates to the surface treatment of civil aircraft wheels, and is a tool in the process of spraying paint for the hub of the aircraft. Background technique [0002] During the maintenance of civil aircraft wheels, damage, performance degradation or state deterioration of the wheels due to corrosion often occurs, and the surface of the wheel is painted as a very important means of metal anti-corrosion protection. A good paint protection layer is continuous, intact and well bonded, and can act as a barrier to inhibit the intrusion of corrosive media. The paint layer of the machine wheel is divided into primer and top coat. When painting, some parts do not need to be painted, such as the bearing cup installation hole, the thermal plug installation hole, the transmission block screw installation hole, the air hole, etc.; some parts only need to be sprayed. Primer, such as grease to seal the installation groove, the transmission block install...
