Description
Technical Field
The utility model relates to a gas turbine assembling and machining tool, in particular to a stator blade ring assembling and machining tool.
Background
The gas turbine takes air as a medium, sucks the air by a compressor, continuously compresses the air, and the compressed air with gradually increased temperature enters a combustion chamber to be mixed with fuel, so that the pressure is increased. The high-temperature and high-pressure fuel gas is sprayed out from the combustion chamber to push the compressed air of the compressor to continuously perform thermodynamic cycle on one hand and push the turbine blades to perform work on the other hand. The whole process is the conversion of heat energy and potential energy of fuel gas (fuel) into kinetic energy. Because the application range of the stator blade ring in the assembly of the gas turbine and the aeroengine is very common, the stator blade ring needs to bear high temperature and air flow pressure of hundreds of degrees in the working process of the gas compressor, and the high-temperature and high-corrosiveness working environment of the stator blade ring ensures that the self-characteristic requirement of the stator blade ring is higher. At present, the stator blade ring with a similar structure is not provided with an effective assembling tool, so that the assembling and processing are integrated, and a tool with a simpler structure is needed to realize the integration of the assembling and the processing.
Disclosure of Invention
The utility model aims to provide a stator blade ring assembling and machining composite tool suitable for assembling and turning a stator blade ring of a high-pressure compressor in the assembling process of a gas turbine.
The purpose of the utility model is realized in the following way:
the utility model relates to a composite fixture for assembling and processing a stator blade ring, which is characterized in that: including base, little clamp plate, ring, lead screw, base and ring are located assembly platform, and the tenon terminal surface of admitting air of the blade of preassembling and processing is laminated with the base terminal surface, and the tip of little clamp plate is installed in the blade top and is fixed on the base through bolt, outer hexagonal nut, installs hexagon socket head cap screw in the ring, and hexagon socket head cap screw pushes up the blade, makes its and the laminating of the interior pore surface of base.
The inventive tool may further comprise:
1. the large pressing plate is arranged above the ring, and the ring is fixed on the assembly platform by installing the lead screw in the large pressing plate and the ring.
2. The small pressing plate and the matched end of the blade exert outward pulling and pressing force on the blade.
The utility model has the advantages that: the utility model can integrate the assembly and the processing of the stator blade ring with the structure, thereby greatly avoiding the waste of tooling resources, reducing the consumption of manpower and material resources and improving the working and production efficiency.

FIG. 3 is a schematic illustration of vane ring drilling assembly.
Detailed Description
The utility model is described in more detail below, by way of example, with reference to the accompanying drawings:
with reference to fig. 1-3, the static blade ring assembling and processing composite tool mainly comprises a pressing plate 1, an outer hexagonal bolt 2, a spherical gasket 3, a base 4, an inner hexagonal bolt 5, a ring 6, a large pressing plate 7, a nut 8 and a screw rod 9. All nonstandard part materials are 45# steel and are blackened. The tool utilizes the base 4, jackscrews and the pressing plate 1 to install the whole circle of blades of the stator blade ring, and plays a role in fixing the stator blade.
The outer hexagonal bolt 2 is M8 multiplied by 40, the spherical washer 3 is GB849-8, the inner hexagonal bolt 5 is M8 multiplied by 40, the nut 8 is M8, and the lead screw 9 is M8 multiplied by 120.
And placing the static blade ring assembling and processing composite tool on a special assembling turntable of the static blade ring, placing each static blade into the tool by taking the end face of the tenon at the air outlet end as the bottom face, arranging one by one until the last blade is placed, and carrying out grinding of less than or equal to 0.05mm on two sides of certain specified blades for meeting the total gap required by a drawing. After the blades are installed, the blades are pre-tightened by the pressing plates 1, the outer hexagonal bolts 2 and the spherical gaskets 3 corresponding to each blade, so that the tenon end face of the air inlet end of each blade is attached to the end face of the base 4. At this time, the ring 6 is put on an assembly platform, the position of the tool is adjusted, the tool is fixed on a rotary table through a large pressing plate 7, a nut 8 and a screw rod 9, and the inner hexagon bolts 5 are installed, and the lengths of all corresponding stationary blades are adjusted to be tightly propped against, so that the stationary blades are completely attached to the inner hole surface of the base 4. And locking the outer hexagonal bolt 2 by using a spanner to finish the preliminary assembly work.
The disassembly ring 6, the large pressing plate 7, the nut M88 and the screw rod 9 have the functions of pulling outwards and compacting simultaneously due to the specificity of the pressing plate 1, so that all static blades are firmly fixed in the tool base. And integrally placing the assembled static blade ring assembly and machining composite tool on a vertical lathe platform, determining a standard through an inner hole of the alignment tool, and clamping and turning all parts of the blade top of the static blade ring once to ensure the drawing size.
And (3) integrally placing the turned stator blade ring assembly and machining composite tool on a triaxial machining center machining platform, cushioning the bottom surface of the blade to be drilled by using an adjustable jack, and drilling and reaming the top end surface of the stator blade to be drilled by determining a reference through an inner hole of an alignment tool so as to ensure the drawing requirement.
