Technical Field

[0001] The utility model relates to the technical field of engine ring processing and application, in particular to a rapid positioning and clamping tool for aircraft engine rings. Background Art

[0002] The aircraft engine is the heart of the aircraft and is used in various commercial aircraft and defense aircraft. Among them, ring forgings are key forgings for aircraft engines. They are formed by rolling technology and have the advantages of dense structure, high strength and good toughness. They determine the performance and service behavior of key aviation components to a considerable extent. Aviation difficult-to-deform metal ring forgings are made of "difficult-to-deform" materials such as high-temperature alloys, titanium alloys, and high-strength steels. They are processed by rolling technology and play the role of containment, connection, support, and sealing. They are important components in aircraft engines.

[0003] At present, when processing engine rings, they need to be clamped, positioned and fixed in position. During the use of clamping, traditional clamping tools generally perform a single clamping and fixing of the rings from the outside to the inside or a stretching and fixing from the inside to the outside. When processing different rings, it is necessary to select clamping tools according to their clamping methods, which delays the processing efficiency in the positioning and clamping processing of the rings. Therefore, the utility model proposes a rapid positioning and clamping tool for aircraft engine rings. Utility Model Content

[0010] The utility model is further configured as follows: the bottom of the rotating shaft is rotatably connected to the top center of the mounting plate.
