Description

Heavy gas turbine movable vane shroud position Z type breach detects rapid tool

Technical Field

The utility model belongs to the field of detection tools, and particularly relates to a Z-shaped notch detection rapid tool for a blade shroud part of a heavy-duty gas turbine.

Background

The heavy-duty gas turbine movable vane mainly comprises a vane shroud, a vane body, a platform and a tenon, wherein the vane shroud is an important part of the vane. The structural characteristic values of the blade crown working surface meshing angle, the crown angle and the like directly influence the operation strength, vibration, reliability, service life of the blade and even the operation safety of a gas turbine. The measurement of the size of the tip shroud engagement angle is particularly important. However, manual detection cannot be performed after the existing blade shroud is machined, three-coordinate detection is adopted, the period is long, the time and labor cost are high, and the requirements of workers cannot be met.

SUMMERY OF THE UTILITY MODEL

Utility model purpose: in order to overcome the defects of the prior art, the utility model provides a quick Z-shaped notch detection tool for a blade crown part of a movable blade of a heavy-duty combustion engine.

The technical scheme is as follows: a Z-shaped notch detection rapid tool for a blade shroud part of a heavy-duty gas turbine rotor blade comprises a base, an angle block, a tenon clamp, a tenon clamping rod, a first blade shroud detection standard block and a second blade shroud detection standard block;

an angle block is fixedly installed at one end of the base, a tenon fixture is fixedly installed at the top of the angle block, a tenon clamping rod is arranged on the tenon fixture, a tenon is clamped through the tenon fixture and the tenon clamping rod, the installation posture of the blade is realized through the angle block, and manual measurement is facilitated;

the other end fixed mounting of base have first blade shroud test standard piece and second blade shroud test standard piece, first blade shroud test standard piece and second blade shroud test standard piece set up relatively, blade shroud department has space angle, first blade shroud test standard piece and second blade shroud test standard piece need install according to base upper groove side locating surface, guarantee that test standard piece reference surface and blade shroud are detected the face and keep parallel, detect the clearance of blade shroud to first blade shroud test standard piece and second blade shroud test standard piece through the clearance of clearance gauge, judge whether it accords with the drawing requirement.

Has the advantages that: the tool has important significance for optimizing a process route, reducing detection cost and shortening maintenance period, improves the working efficiency of people and meets the requirements of workers.

Detailed Description

Examples

As shown in fig. 1-5, a fast tool for detecting a Z-shaped notch at a blade shroud part of a heavy-duty gas turbine includes a base 1, an angle block 2, a tenon fixture 3, a tenon clamping rod 4, a first blade shroud detection standard block 5, and a second blade shroud detection standard block 6.

One end fixed mounting of base 1 have angle piece 2, the top fixed mounting of angle piece 2 have tenon anchor clamps 3, tenon anchor clamps 3 on be equipped with tenon holding rod 4, carry out the centre gripping to the tenon through tenon anchor clamps 3 and tenon holding rod 4, realize the installation posture of blade through angle piece 2, make things convenient for manual measurement.

The other end fixed mounting of base 1 have first blade shroud detection standard block 5 and second blade shroud detection standard block 6, first blade shroud detection standard block 5 and second blade shroud detection standard block 6 set up relatively, blade shroud department has space angle, so lead to first blade shroud detection standard block 5 and second blade shroud detection standard block 6 to need to install according to base 1 upper groove side locating surface, guarantee that detection standard block reference surface and blade shroud are detected the face and keep parallelism, as shown in figure 4, detect the clearance of blade shroud to first blade shroud detection standard block 5 and second blade shroud detection standard block 6 through the feeler gauge, judge whether it accords with the drawing requirement, this instrument has the significance to optimizing process route, reduce the detection cost and shorten maintenance cycle, improve people's work efficiency, staff's demand has been satisfied.

The technical solutions in the embodiments of the present invention are clearly and completely described above, so that those skilled in the art can better understand the advantages and features of the present invention, and thus the protection scope of the present invention is more clearly defined. The embodiments described herein are only a few embodiments of the present invention, rather than all embodiments, and all other embodiments that can be derived by one of ordinary skill in the art without inventive faculty based on the embodiments described herein are intended to fall within the scope of the present invention.
