Abstract
The utility model provides a drilling and fixing tool for a stator blade ring of a compressor casing, which comprises a pressing plate, bolts, nuts A and a base; the base is connected with the compressor casing through a bolt and a nut A; and the base is provided with a pressing plate, and the pressing plate fastens the outer ring of the stationary blade ring from inside to outside. The utility model meets the requirement of the exposed size of one side of the stator blade ring relative to the split surface of the casing in the drawing, and prevents the situation that the hole position is not correct after the stator blade ring is split and closed up to cause the position to be drilled. The utility model solves the problems that the position of the drilled hole is not correct and the relative size of the split surface in the compressor casing exposed from the drawing changes due to displacement generated by processing stress in the process of matching the stator blade ring with the drilled hole in the casing.
Description
Technical Field
The utility model belongs to the field of gas turbine manufacturing, and particularly relates to a fixed tool for drilling a stationary blade ring of a compressor casing.
Background
The stator blade ring has a very common application range in the assembly of gas turbines and aeroengines, and needs to bear high temperature and air flow pressure of hundreds of degrees in the working process of gas compressors, and the high-temperature and high-corrosiveness working environment of the stator blade ring ensures that the stator blade ring has higher requirements on the self characteristics of the stator blade ring. The stator blade ring is arranged in a high-pressure compressor casing and a low-pressure compressor casing, and in the installation process, the stator blade ring is required to be matched with a drill and reamed according to the hole position of the casing and fixed in a casing groove by using a screw. After the stator blade ring is positioned in size relative to the split surface in the casing in the assembly process, the stator blade ring is fixed by a special fixture and is matched with a drill hole, and due to the specificity of the casing structure of the high-pressure compressor and the low-pressure compressor, the special fixture which effectively integrates the positioning of the size and the fixation is required to fix the stator blade ring, so that the stator blade ring is ensured not to generate displacement due to the radial stress of the machining in the drilling process.
Disclosure of Invention
The utility model aims to provide a drilling and fixing tool for stator blade rings of a compressor casing, which is applicable to high-pressure and low-pressure compressor casings of stator blade rings of all medium-sized and small-sized gas turbines with similar structures.
A drilling and fixing tool for a stator blade ring of a compressor casing comprises a pressing plate, bolts, nuts A and a base; the base is connected with the compressor casing through a bolt and a nut A; and the base is provided with a pressing plate, and the pressing plate fastens the outer ring of the stationary blade ring from inside to outside.
Further, the pressing plate is mounted on the base through a stud bolt and a nut B.
The utility model has the beneficial effects that: the utility model meets the requirement of the exposed size of one side of the stator blade ring relative to the split surface of the casing in the drawing, and prevents the situation that the hole position is not correct after the stator blade ring is split and closed up to cause the position to be drilled. The utility model solves the problems that the position of the drilled hole is not correct and the relative size of the split surface in the compressor casing exposed from the drawing changes due to displacement generated by processing stress in the process of matching the stator blade ring with the drilled hole in the casing.

Fig. 1 is a schematic diagram of a tool for drilling and fixing a stator blade ring of a compressor casing.
Fig. 2 is A-A view of fig. 1 in accordance with the present utility model.
Detailed Description
The utility model is further described below with reference to the accompanying drawings.
1-2, the fixed tooling for drilling the stator blade ring of the compressor casing is characterized by comprising a pressing plate 8, bolts 4, nuts A5 and a base 1; the base 1 is connected with the compressor casing 2 through the bolts 4 and the nuts A5, the stator blade rings 3 with corresponding stages are installed, one side, with the requirement for relative exposure size, of the stator blade rings on the middle split surface of the compressor casing in the drawing is attached to the notch of the base 1, the base 1 is used for positioning and fixing the size of the stator blade rings 3, and the subsequent drilling process is guaranteed not to generate radial displacement through the fixation of the tool. The base 1 is provided with a pressing plate 8, the pressing plate fastens the outer ring of the stator blade ring 3 from inside to outside, the outer ring of the stator blade ring (the stator blade ring after being divided into half is easily closed by internal stress) is completely attached to the casing, the other side is assembled by the same method, the radial direction of the side stator blade ring 3 can be fixed by using jackscrews to be matched with universal heads, and the upper half and the lower half of the compressor casing 2 are conveyed to a drilling hole after the assembly is completed. All nonstandard parts are made of 45# steel, and the surfaces of the nonstandard parts are blackened, so that the structure of the utility model is suitable for stator blade ring high-pressure and low-pressure compressor cases of all medium-sized and small-sized gas turbines with similar structures.
