Abstract

The invention belongs to the technical field of forcing processing equipment and relates to a rolling device and a rolling method for a chromium coating layer on an inner hole wall of the outer barrel end of a damper. The rolling device for the chromium coating layer on the inner hole wall of the outer barrel end of the damper cooperates with a machine tool to finish rolling the surface of the inner wall of a cylindrical work piece. The rolling device for the chromium coating layer on the inner hole wall of the outer barrel end of the damper comprises a work piece locating and clamping mechanism and a rolling cutter. The work piece locating and clamping mechanism comprises a work piece left end locating unit and a bearing arranged on the outer wall of the right end of an outer barrel work piece of the damper, the work piece left end locating unit is arranged on a machine tool chuck, and the bearing is matched with the machine tool and a cutter holder. The rolling cutter is arranged on the machine tool cutter holder. The rolling device for the chromium coating layer on the inner hole wall of the outer barrel end of the damper solves the problem of oil dot seepage at the sealed position of the end of the damper of an air vehicle landing gear and guarantees the work reliability of the damper of the air vehicle landing gear can meet the design requirements.

Description

technical field [0001] The invention relates to a rolling device and a rolling method for a chrome-plated layer on an inner hole wall of an outer cylinder end of an aircraft landing gear shock absorber, and belongs to the technical field of pressure treatment equipment. Background technique [0002] Shock absorbers are all arranged in the landing gear assembly of the aircraft to absorb the impact energy when the aircraft lands, reduce the impact force, and weaken the bumps and jumps when the body lands and slides. as attached figure 1 The shock absorber outer cylinder 1 of a kind of aircraft landing gear shown, its right end inner wall 1-1 place is equipped with sealing structure, the left end place is provided with left connecting hole 1-4, also is provided with on its left side There are a first pin sleeve 1-2 and a second pin sleeve 1-3 installed on the outer wall of the shock absorber through two support frames 1-5. [0003] During the maintenance of the aircraft landi...
