Embodiment Construction

[0021] It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and examples.

[0022] see figure 2 as shown, figure 2 A cut-away three-dimensional structural view of the casing is schematically shown. according to figure 2 It can be known that the casing 30 has a cavity 40 , and a plurality of blades 50 are arranged on the inner wall of the cavity 40 . A plurality of blades 50 are arranged on the inner wall of the cavity 40 in an annular structure. After the blade 50 is installed, it is usually necessary to process the end of the blade 50 away from the inner wall of the cavity 40. In order to prevent the blade 50 from jumping and breaking during the processing, the present invention provides a blade processing damping device in the casing.

Abstract

The invention provides a damping device for machining blades in a case. The damping device for machining the blades in the case comprises a body and locating parts. The locating parts are arranged on the body and matched with the blades in a cavity of the case. By adopting the damping device for machining the blades in the case to generate damping, it is not needed to clean the case or the inner structure of the case; besides, the damping device is environmentally friendly and free of pollution, greatly lowers the production and manufacturing cost of the case and increases the percent of pass of the finished case.

Description

technical field [0001] The invention relates to the technical field of aero-engine casings, in particular to a processing damping device for blades in the casing. Background technique [0002] In order to increase the rigidity of the blades in the casing when they are processed, the method of pouring wax into the casing is generally used to fix the blades. This method is very inefficient, and it takes a long time to pour wax, melt the wax, and clean the residual wax, and the cost is high. Sometimes failures occur, and there is a small amount of wax residue in the casing, which affects the quality. Contents of the invention [0003] The main purpose of the present invention is to provide a damping device for machining blades in the casing to solve the problem of high cost of processing blades in the casing in the prior art. [0004] In order to achieve the above object, the present invention provides a blade processing damping device in the casing, which includes a main bo...
