Problems solved by technology

[0003] The tenons of the existing heavy-duty gas turbine rotor blades have complex structures, many surfaces to be processed, and high processing precision. However, there is currently no special device for fixing the rotor blades to facilitate processing of the tenons, which may cause dynamic problems during processing. The blade is offset, resulting in large processing errors, material waste, etc., which makes it impossible to meet the later assembly requirements; moreover, when actually processing the surface of different parts of the blade tenon, it is necessary to constantly turn the blade, the entire processing process is cumbersome and time-consuming , increasing the labor intensity of the operator

Embodiment 1

[0037] refer to image 3 As shown, the existing moving blade 3 is often composed of tenon 31, extension root 32 and blade body 33, wherein the tenon 31 has multiple processed and formed surfaces for later assembly with other parts, so its processing The precision requirement is high. The extension root 32 is located between the tenon 31 and the blade body 33. The protruding part on both sides is usually called the extension root wing 321. The blade body 33 is relatively twisted between two adjacent sections and the cross-sectional area is given by For twisted blades with variable cross-sections that gradually increase from the root to the top, the concave side of the blade body 33 is usually called the pressure side 331 , and the convex side of the blade body 33 is called the suction side 332 .

[0038] In order to fix the moving blade 3 in the process of processing the tenon 31 of the moving blade 3 and prevent it from shifting, refer to figure 1 and figure 2 , this embodi...

Embodiment 2

[0046] The present invention provides a heavy-duty gas turbine rotor blade tenon integrated processing method. The movable blade 3 is fixed by using the fixture for the heavy-duty gas turbine rotor blade integrated processing of the above-mentioned embodiment 1, and the fixed rotor blade 3 refers to Figure 4 and Figure 5 As shown, the processing method includes the following processing steps:

[0047] S1. Place the moving blade 3 to be processed on the jig so that the tenon 31 to be processed of the moving blade 3 is facing upwards, so as to facilitate the subsequent processing of the tenon 31;

[0048] S2. Fix the extension root 32 of the moving blade 3 through the first clamping assembly 21, and fix the blade body 33 of the moving blade 3 through the second clamping assembly 22, so as to prevent the machining error caused by the deviation of the moving blade 3 during the processing;

[0049] S3. Fix the fixture together with the moving blade 3 on the working table of the ...

Abstract

The invention relates to the technical field of gas turbine movable blade machining, and discloses a clamp for integrated machining of a heavy gas turbine movable blade tenon. The clamp comprises a transfer disc, and a clamp body arranged on the transfer disc; the clamp body sequentially comprises a first clamping assembly and a second clamping assembly from top to bottom, the first clamping assembly is used for fixing the extending root of a movable blade, the second clamping assembly is used for fixing a blade body of the movable blade, through the first clamping assembly and the second clamping assembly, the extending root portion and the blade body portion of the movable blade are fixed, the movable blade can be firmly fixed, meanwhile, invention further discloses an integrated machining method of the heavy gas turbine movable blade tenon, through the method, when the movable lade tenon is machined, the movable blade does not need to be turned over in a reciprocated manner, the machined movable blade tenon is higher in precision, and the assembling needs are met.

Description

technical field [0001] The invention relates to the technical field of gas turbine rotor blade processing, in particular to a fixture for integrated processing of a heavy-duty gas turbine rotor blade tenon and an integrated processing method thereof. Background technique [0002] Turbine rotor blades for heavy-duty gas turbines are one of the important parts of heavy-duty fuel engines, which usually include three parts: tenon, extension root and blade body. At present, there are still a large number of processing technical problems to be solved urgently for turbine blades for heavy gas turbines, such as key technologies such as tenon processing of turbine blades for heavy gas turbines. [0003] The tenons of the existing heavy-duty gas turbine rotor blades have complex structures, many surfaces to be processed, and high processing precision. However, there is currently no special device for fixing the rotor blades to facilitate processing of the tenons, which may cause dynam...
