Abstract

The invention discloses an inner hole electroplating fixture for an airplane outer barrel part, and relates to the electroplating field of airplane parts. The inner hole electroplating fixture for the airplane outer barrel part comprises a cathode protection ring (1), an upper anode locating plate (2), a lower anode locating plate (3) and a conformal anode (4), wherein the cathode protection ring (1) is fixed at the upper end of the airplane outer barrel part; the upper anode locating plate (2) is fixed on the cathode protection ring (1); the lower anode locating plate (3) is fixed at the bottom of the airplane outer barrel part; and the conformal anode (4) is fixed between the upper anode locating plate (2) and the lower anode locating plate (3). The inner hole electroplating fixture disclosed by the concrete embodiment solves the problems that an anode and an inner hole are not easily arranged in a concentric way, and the conformal anode easily deforms when being heated. Therefore, the problems that a plating layer is unilateral-shaped or ellipse and is not even can be solved, and the inner hole size plating requirement on the part can be met.

Description

technical field [0001] The invention relates to the field of electroplating of aircraft parts, in particular to an electroplating fixture for inner holes of outer cylinder parts of aircraft. Background technique [0002] The outer cylinder parts of the aircraft require chrome plating on the size of the inner hole. The traditional mounting method: the parts are insulated with iron sheets, and the inner holes are made of lead sheets as pictographic anodes and fixed with iron wires. This method is likely to cause pictographic anodes to not be well fixed in the center. The position of the anode and the inner hole cannot be concentric and coaxial, and the lead skin (δ=1mm) is easily deformed due to overheating during the electroplating process, making the coating unilateral, uneven, the inner hole is elliptical, and the port is easy to produce Chromium tumors and other phenomena cannot meet the requirements for inner hole size plating.
