Conical radome machining and fixing fixture

Abstract

The invention provides a conical radome machining and fixing fixture, and belongs to the technical field of machine tool fixtures. The conical radome processing and fixing fixture comprises an overall support, a positioning device, a regulating device and a clamping mechanism; a disc base, a circular top plate and four pillar type columns are connected into a whole through the overall support by adopting positioning pins; the positioning device is arranged on the four pillar type columns in a sleeving mode by adopting an upper aluminum casting, and the center of the upper aluminum casting is provided with a nylon sleeve used for positioning a radome; the regulating device is arranged on the four pillar type columns in the sleeving mode by adopting a lower aluminum casting, and four spiral regulating mechanisms are evenly distributed on the lower aluminum casting; four pressing plates fixed by bolts are evenly distributed on the circular top plate of the clamping mechanism. The fixture can be suitable for regulating, positioning and clamping of radome parts of various different specifications for machining evenly distributed inner wall blind holes on a numerical control machine tool, meets the automation requirement of evenly distributed inner wall blind hole machining of the radome parts, and the machining efficiency is greatly improved.

Description

technical field [0001] The invention relates to a processing and positioning fixture for a tapered radome, belonging to the technical field of machine tool fixtures. Background technique [0002] The radome is a device used to protect radar in aerospace. Due to its harsh working conditions and special functions, its structure and shape are particularly complicated, which makes it difficult to adjust and adjust on the general fixture when processing the inner wall holes of radome parts. Positioning and clamping, and it is even more difficult to realize the adjustment, positioning and clamping of a variety of different specifications of the radome parts. [0003] At present, the patents related to the radome, such as the special fixture for the outer surface mentioned in the Chinese patent application 200910046260.1, is positioned with the inner cavity of the radome, and it is impossible to process the blind hole on the inner wall; It seems that the fixture can be used to pro...

[0002] The radome is a device used to protect the radar in aerospace. Due to its harsh working conditions and special functions, its structure and shape are particularly complicated, which makes it difficult to adjust on the general fixture when processing the inner wall holes of radome parts Positioning and clamping, and it is even more difficult to adjust, position and clamp radome parts of different specifications

[0003] At present, the patents related to the radome, such as the special fixture for the outer surface mentioned in the Chinese patent application 200910046260.1, is positioned with the inner cavity of the radome, and it is impossible to process the blind hole on the inner wall; It seems that the fixture can be used to process blind holes on the inner wall, but it cannot adjust the axial verticality of the radome, and cannot guarantee the machining accuracy of uniformly distributed blind holes on the inner wall, and cannot adapt to the positioning and clamping requirements of various specifications of radome parts
