Embodiment Construction

[0030] The present application will be described in further detail below in conjunction with the examples, but the implementation manner of the present application is not limited thereto.

[0031] Refer to the attached figure 1 , the thin-wall special-shaped pipe has the following characteristics: the shape of the pipe fitting is a non-circular structure, the wall thickness of the pipe fitting is thin, there is a through hole in the middle, and there are high-precision step holes at both ends. Therefore, traditional chucks cannot directly clamp thin-walled special-shaped tubes for processing. Therefore, this embodiment discloses a processing method for high-precision inner circular holes of thin-walled special-shaped tubes, which solves the clamping problem of thin-walled special-shaped tubes during processing. The processing and clamping of special-shaped pipes mainly includes aluminum spacer 1, end cap 2, slotted bushing 3 and positioning ring 4. The processing method speci...

Abstract

The invention relates to the technical field of machining, and discloses a machining method of a high-precision inner circular hole of a thin-wall special-shaped pipe. The machining method is suitablefor machining the high-precision inner hole of the thin-wall special-shaped pipe part in a non-circular shape on a lathe and solves the problem that a traditional chuck cannot directly clamp the thin-wall special-shaped pipe for machining. When machining, the coaxiality precision of inner holes in the two ends of the part is high, and the cylindrical precision is high.

Description

technical field [0001] The application relates to the technical field of mechanical processing, in particular to a processing method for high-precision inner circular holes of thin-wall special-shaped pipes. Background technique [0002] In the aerospace and aviation industries, there is a special type of part, which is a special-shaped thin-walled tubular part with high-precision holes at both ends. At the same time, due to the requirements of the use characteristics, the holes at both ends have extremely high coaxiality and cylindricity. Requirements, so the traditional chuck cannot be clamped, so the parts cannot be processed by turning. At present, horizontal boring machines are mostly used for the processing of this special type of parts. However, due to the difficulty in positioning and clamping the parts, the qualified rate of the parts is low and the cost is also high. Contents of the invention [0003] In order to overcome the above-mentioned problems and deficie...
