The invention provides a method and a clamping device which can be used for surface treatment such as cleaning, passivation, chemical oxidation, etc. in an elongated tubular metal part. The clamping device comprises a left clamping plate, a right clamping plate, a hose, a solution pump and a solution box. When the clamping device works, the solution pump is powered on. By the pumping action of the solution pump, the solution in the solution box flows through a solution control valve, the right clamping plate, the inner wall of the elongated tubular metal part, the left clamping plate in order, and returns to the solution box through the retractable hose after reaching the solution pump, so that the process for treating the surface of the inner wall surface of the elongated tubular metal part is completed.
Description
technical field [0001] The present application relates to the technical field of surface treatment of aircraft parts, in particular to a clamping device for surface treatment of the inner wall of a slender tubular metal part. Background technique [0002] In the design and manufacture of aircraft, slender tubular metal parts such as stainless steel, copper alloy, and aluminum alloy are widely used in critical positions such as oxygen conduits, hydraulic conduits, and exhaust conduits. During the extrusion molding process of this type of part material, accompanied by exothermic phenomenon, the instantaneous temperature of the material surface rises, resulting in relatively serious oxide skin on the inner wall and outer surface of the pipe, and the subsequent stress relief annealing treatment makes the oxide skin Further aggravation and densification. Most of these parts used in aircraft are not only very small in diameter, generally with an inner diameter of 2mm to 5mm, but ...
