Abstract

The invention provides a special fixture for special-shaped waveguide tube abrasive flow finishing processing. The special fixture is characterized by comprising a workpiece external fixture body andan internal profiling core mold (6); the workpiece external fixture body comprises a base (1), a lower limiting plate (2), a supporting ring (3), an upper limiting plate (4) and an upper cover (5). According to the special fixture, a set of reasonable and usable fixture is provided for reducing the surface roughness of a special-shaped waveguide tube channel during abrasive flow finishing processing. The special fixture is reasonable in design, simple in structure and obvious in effect.

Description

technical field [0001] The invention relates to a processing fixture, in particular to a special fixture for inner channel abrasive flow processing equipment, in particular to a special fixture for abrasive flow finishing of special-shaped waveguides. Background technique [0002] The waveguide is used to transmit ultra-high frequency electromagnetic waves, through which the pulse signal can be transmitted to the destination with minimal loss. It is a hollow metal conduit or a metal-coated tube with a very smooth inner wall. For the special-shaped waveguide for 3D printing, the material is aluminum alloy, and the inner wall of the blank is very rough, which is far from meeting the requirements for use. Because the special-shaped waveguide has a small inner diameter and complex shape, the traditional surface finishing technology cannot meet the processing requirements. [0003] The abrasive flow processing technology is to let the abrasive medium flow through the surface of ...
