Abstract

The invention provides a special clamp for the abrasive material flow finishing machining of a variable-cross-section specially-shaped channel structure. The special clamp comprises a bottom base plate (9) and a base (5) and is characterized in that the base (5) is arranged in a clamp upper cover (1) in a sleeving manner, the clamp upper cover (1) is fixed to the bottom base plate (9), a workpiece (2) is mounted on the base (5), a fixing ring (4) is mounted on the base (5), and a sharp edge protecting rod (3) is mounted on the fixing ring (4); and an inserting hole is processed in the cylindrical side edge of the clamp upper cover (1), and the main body part of a flow guiding column (7) is inserted into a runner (10) of the workpiece (2). Through the one-time flowing of an abrasive material, the finishing machining of a part comprising the variable-cross-section specially-shaped channel structure is realized. The device is simple, is easy to mount and disassemble, and can realize the high-efficiency and high-precision machining of the part comprising the variable-cross-section specially-shaped channel structure.

Description

technical field [0001] The invention relates to a surface processing technology, in particular to a special fixture for abrasive flow finishing for workpieces with complex variable cross-section special-shaped channel structures and high surface quality requirements, specifically a variable cross-section special-shaped channel structure Abrasive streamer finishing special fixture. Background technique [0002] A large number of components in aerospace engines and gas turbines contain complex and irregular shapes. With the continuous improvement of aerodynamic performance requirements, the profile of the airflow channel is becoming more and more complex, and the requirements for dimensional accuracy and surface quality are getting higher and higher. And there is a tendency to make overall. [0003] In order to solve the overall manufacturing process of integral components with complex variable cross-section and special-shaped channel structures, after the high-efficiency rem...
