Embodiment Construction

[0025] The processing method of the present invention will be described in detail below by taking the vibration damping ring as an example.

[0026] A processing method for cutting the circumferential surface of a sleeve-like part, comprising the following steps:

[0027] Step 1: Use the lathe to turn the outer diameter, inner diameter and thickness of the part;

[0028] Choose the casting surface that is not processed, that is, use the positioning scheme of the outer circle and end face of the large end as the rough reference for clamping, rough machine one end, and then use the processed end face and outer circle as the clamping reference (craft table) to rough machine the other end For the inner and outer circles and end faces, the outer diameter of the parts after processing reaches the outer diameter size required by the drawing, and a machining allowance of +0.7~+1mm is left;

[0029] Step 2: Use a drill press and a special fixture to drill the angular positioning holes...

Abstract

The invention discloses a machining method for cutting circumference sleeve parts, belonging to the technical field of rotor parts used for aircraft engines and airspace engines. The invention provides a machining method for cutting circumference sleeve parts, which can guarantee the technical requirement of precise parts. The machining method comprises the following steps of: turning the outer diameter, the inner diameter and the thickness of a machine tool part; positioning holes by the angle direction of a drilling machine and a special fixture and drill part; semifinishing an inner circleand an excircle by an inner-circle grinding machine and an outer-circle grinding machine; carrying out heat treatment; carrying out finish machining the inner circle and the excircle of the part by the inner-circle grinding machine and the outer-circle grinding machine; grinding and machining the outer boss of the part by an excircle grinding machine; grinding and machining the inter boss of the part by an inner circle grinding machine; removing a technical table; grinding an end surface; deburring, grinding a boss seamed edge fillet, and stably processing; carrying out magnetic powder flaw detection; carrying out final detection; and carrying out chemical passivation.

Description

technical field [0001] The invention belongs to the technical field of machining rotor components for aviation and aerospace engines, and in particular relates to a machining method for cutting the circumferential surface of sleeve-like parts. Background technique [0002] The inner and outer circumferential surfaces of sleeve parts are processed with equal multi-bosses, usually by wire cutting or milling. This processing method has low processing dimensional accuracy and surface roughness, and it is extremely difficult to meet the technical requirements of precision parts. Contents of the invention [0003] Aiming at the problems existing in the prior art, the present invention provides a machining method for cutting the circumferential surface of sleeve-like parts that can meet the technical requirements of precision parts. [0004] In order to achieve the above object, the present invention adopts the following technical scheme, a processing method for cutting the circ...
