Embodiment

[0021] A processing method for anti-deformation of thin-walled disk parts, (1) design fixture: such as figure 1 As shown, the fixture is a flat piece, and there is a centering boss 201 on the upper surface of the fixture, which can stabilize the part to be processed and facilitate the smooth progress of processing. An "L"-shaped through hole 202 is opened on the side of the fixture. The other end of the hole is opened on the upper surface of the fixture, the orifice on the side is the inlet 204, and the orifice on the upper surface is the outlet 203, to ensure that after the part is loaded into the fixture, the outlet 203 is located inside the cavity of the part, and close to the center of the cavity; (2) Install the fixture: then install the related fixture on the faceplate of the CNC machine tool, and align the fixture; (3) Install the workpiece to be processed: clamp the workpiece to be processed on the fixture, and align it Workpiece to be processed; (4) pouring low-meltin...

Abstract

The invention discloses an anti-deformation machining method for a thin-wall disc-shaped part. A clamp is installed on a faceplate, the clamp is aligned, and a through hole is formed in the clamp; a to-be-machined part is clamped on the clamp, and the to-be-machined part is aligned; low-melting-point metal is poured into the position of an inner cavity between the clamp and the part through the through hole of the clamp, and it is ensured that the inner cavity is filled with the low-melting-point metal; and after the low-melting-point metal is cooled to the room temperature, the to-be-machined part is machined according to a conventional method, and the workpiece is taken down after machining is completed. Due to application of the low-melting-point technology and design of the metal clamp, the problems that the deformation of the thin-wall part is large in the machining process, tool vibration is likely to happen, and the size is hard to ensure are solved finally.

Description

technical field [0001] The invention relates to the technical field of processing thin-walled disk parts, in particular to a deformation-resistant processing method for thin-walled disk parts. Background technique [0002] With the needs of social development, in the manufacturing process of aviation products, the quality requirements of aviation products are getting higher and higher, so the design and manufacturing capabilities need to be improved, and the integration of aero-engine components is also getting higher and higher. It tends to be integrated, lightweight, and precise, and the surface structure is becoming more and more complex, and the requirements for product processing are getting higher and higher. Traditional processing methods are difficult to meet the requirements of new machine development. The wall thickness of disc parts is gradually getting thinner and the shape and position tolerance is getting higher and higher under the condition of satisfying the ...
