Description

Technical Field

[0001] The utility model relates to the technical field of turbine shell processing, in particular to a clamping device for turbine shell processing. Background Art

[0002] A turbine is a rotary power machine that converts the energy of a flowing working fluid into mechanical work. It is one of the main components of aircraft engines, gas turbines and steam turbines. Usually, a corresponding turbine shell is arranged on the outside of each turbine. The shape of the turbine shell is similar to an involute, and the axis of the impeller is biased to one side. The gap between the outer edge of the impeller and the turbine shell is the smallest. The rotation of the centrifugal wheel causes wind or water to be blown out from the outlet, and the water inlet (or air inlet) enters from the axis of the impeller and is blown out to the outlet at the edge of the turbine shell under the action of centrifugal force. The processing process of the turbine shell requires a fixed clamping device; the turbine shell needs to be tightened during the processing, but due to the specific structure of the turbine shell, the clamping device cannot clamp it well, resulting in the problem of turbine shell offset during the processing, so it needs to be improved.

[0003] Therefore, those skilled in the art have proposed a clamping device for machining a turbine casing to solve the problems raised in the above background. Utility Model Content
