Embodiment Construction

[0032] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further elaborated below.

[0033] like figure 1 and figure 2 As shown, a laser cladding repair method for the wear and tear of the cam arc surface of the aircraft control system, the specific steps are as follows:

[0034] S1: Inspection of damage distribution: measure the size, distribution and manifestation of defects in the damaged part, determine the damaged material that needs to be removed by grinding, mark the repair area, and mark the amount of wear at the same time;

[0035] S2: Repair design: The main failure mode of parts is wear, which is mainly caused by normal wear and tear during use. Since the damage area is small and relatively scattered, the incremental size of the repair is relatively thin. Laser cladding technology is planned to be used for parts. carry out partial repairs;

[0036] S3: Pr...

Abstract

The invention relates to the field of airplane part repairing, in particular to a laser cladding repairing method for abrasion of a circular arc curved surface of a cam of an airplane control system.The laser cladding repairing method comprises the following specific steps of S1, damage distribution inspection; S2, repairing design; S3, process material analysis; S4, repairing through laser cladding; S5, polishing and finishing after repairing; S6, inspection after polishing; S7, assembly inspection; and S8, motion inspection. According to the laser cladding repairing method, the repairing problem of the nonlinear relation of the circular arc curved surface is solved, the technical blank of circular arc curved surface repairing based on the nonlinear relation is filled up, and compared with the traditional technology, the laser cladding repairing method has the remarkable technical progress; and by tracking the using condition of the repaired cam, it is verified that the adopted repairing method and process are safe and reliable, and the remarkable effects of improving the cam quality and reducing the cost are achieved.

Description

technical field [0001] The invention relates to the field of repairing aircraft parts, in particular to a laser cladding repairing method for the wear and tear of a cam arc surface of an aircraft control system. Background technique [0002] The cam of the aircraft control system is installed above the front landing gear, and is used to transmit the action of the pedals to the oil distribution device of the hydraulic mechanism when the front landing gear is lowered, so as to obtain the best wheel deflection angle, so that the aircraft can take off during take-off. Maintain direction during the landing and roll, and have good maneuverability during the slide. Disconnect the hydraulic system from the rudder control system with the nose gear up and lock it in the neutral position. With the prolongation of the service time of the aircraft, the arc surface of the cam is subjected to different degrees of wear tolerance during the long-term working process, and in the corrosive en...
