[0002] Turbine guide vanes are one of the key aerodynamic components of aircraft engines and are also an important key part of the entire engine. They have a large number of parts and have extremely high requirements for processing dimensional accuracy. In recent years, in order to improve the overall performance of the engine, reduce airflow loss and increase structural strength, designers have added a twin-integral casting structure to the turbine guide vanes. This is the twin-integral cast guide vane.

[0003] This type of blade not only has a complex casting process, but also has extremely difficult processing technology. There are air film holes in the blocked area between the two adjacent blade flow channels.

In addition, the double-integrated cast guide blades have an irregular structure, which is difficult to fix stably during processing. At present, their fixing method usually relies on multiple bolts and multiple pressure blocks, which makes the disassembly and assembly process cumbersome and requires removing multiple bolts one by one, which is inconvenient to operate.

The outside of the diverter shell 33 is connected to a number of ventilation hoses 35. A pressure gauge 34 is installed on the front side of the diverter shell 33. The air can be supplied to the pressure locking module 4 through the air expelling part 3, wherein the pressure gauge 34 can judge the pressure applied by the pressure locking module 4 to the pressing plate 5; the pressure locking module 4 includes a connector 41 connected to the ventilation hose 35, and the lower side of the connector 41 is connected to the transfer shell 42.

This arrangement enables the pressure locking module 4 to be installed and positioned in the positioning channel 105 of the seat 1 on the one hand, and to apply pressure to each pressing plate 5 on the other hand, so that each pressing plate 5 can firmly fix the positioned double blade 7; an electrode holder 8 is provided at the double blade 7, and a plurality of electrodes equidistantly arranged are installed on the electrode holder 8, and the electrode holder 8 can be used to perform electrode processing on the air film holes of a row of left parts of the double blade 7, and the valve tube 32 is composed of a tube body and an electric control valve, and the electric control valve and the inflation and suction dual-purpose air pump 31 of the valve tube 32 are electrically connected to the controller 2, and through this arrangement, the controller 2 can control the operation of the valve tube 32 and the inflation and suction dual-purpose air pump 31;The double blade 7 is provided with an electrode holder 29, on which a number of electrodes are installed at equal distances. The electrode holder 29 can be used to process the air film holes in a row of the right part of the double blade 7. The folded airbags 46 are connected to the vents 43. Through this arrangement, the gas in the transfer shell 42 can enter the folded airbags 46 through the vents 43. The folded airbags 46 and the pressure ring 47 are both arranged on the upper side of the pressing plate 5, and the lower end faces of the pressure ring 47 are all connected to the upper end faces of the pressing plate 5. The tight fit ensures that the folded airbag 46, after expanding and expanding due to gas, can compress the compression plate 5. The positioning channel 105 is composed of an upper guide channel and a lower expansion groove. The clamping blocks 455 protrude from the slide 452 and are disposed within the lower expansion groove of the positioning channel 105. The upper end surfaces of the clamping blocks 455 are in contact with the upper inner wall of the lower expansion groove of the positioning channel 105. This arrangement allows the guide locking rod 45 to be fixed to the positioning channel 105 after deployment, thereby securing the compression locking module 4.

[0034] Workflow: The positioning device fixes the double integrally cast guide blades as follows. Note: The electrical appliances used in this application are all externally powered and centrally controlled by the controller 2. First, install the clamping column 6 at the threaded mounting hole 111 with bolts, but do not tighten the bolts yet to ensure that the clamping column 6 can rotate freely. At this time, the clamping block of the clamping column 6 should be set downward to avoid interference with the subsequent placement and installation of the double blades 7. Then, place the double blades 7 on the upper side of each wedge-surface positioning support block 104, and push the double blades 7 backward so that their rear end faces are tightly fitted with the exhaust side positioning block 108 and the front end faces of the arc positioning block 110. At the same time, the right end face of the double blade 7 is fitted with the left end face of the arc positioning block 110. After that, the staff will place the double blade 7, then rotate the pressing column 6 so that the rear end face of the pressing block is in contact with the right rear edge of the double blade 7, and then tighten the bolt to fix the pressing column 6, thereby achieving the initial positioning of the double blade 7. When the double blade 7 needs to be disassembled later, it is only necessary to loosen the bolts of the pressing column 6 so that it can be rotated, and the positioning of the double blade 7 can be cancelled. Therefore, the bolts used here do not need to be completely disassembled. Subsequently, the staff will place each pressing plate 5 on the upper side of each positioning hole 105, and ensure that the lower end face of the corner end of the pressing plate 5 is in contact with the upper end faces of the left and right edges of the double blade 7. Then, the guide locking rod 45 of each locking module 4 passes through the pressing plate 5 and is inserted into the positioning hole 105 to complete the above operation. After the operation, the staff controls the electric valve of the valve tube 32 to open through the controller 2, and runs the inflation mode of the inflation and suction dual-purpose air pump 31. At this time, the airflow enters each compression lock module 4 through the valve tube 32, the diverter shell 33 and each ventilation hose 35. The airflow entering the compression lock module 4 enters the transfer shell 42 through the joint 41, and a part of the airflow enters the conduit 451 of the guide lock rod 45 through the vent 44. As the gas in the conduit 451 continues to increase, it will push each card block 455 to move outward and extend to the lower expansion groove of the positioning channel 105, so that the guide lock rod 45 is unfolded and fixed on the positioning channel 105, thereby completing the fixed locking position of the compression lock module 4, and the other part of the airflow enters the folding airbag 46 through the vent 43, so that the folding airbag 46 expands and stretches downward, pushing the pressure ring 47 downward to press the pressing plate 5. At this time, the staff can judge the pressure of the pressing locking module 4 on the pressing plate 5 through the pressure gauge 34. When the pressure reaches the set value, it shows that the pressure of the pressing locking module 4 on the pressing plate 5 is sufficient to ensure that each pressing plate 5 firmly presses the double blades 7. At this time, the valve pipe 32 is closed by the controller 2 and the operation of the dual-purpose air pump 31 is stopped to complete the fixed positioning of the double blades 7. At this time, the staff can perform electrode processing on the air film holes in the blocking part of the fixed double blades 7. After the processing is completed, when the double blades 7 need to be disassembled, it is only necessary to let the dual-purpose air pump 31 run the suction mode and perform the above-mentioned reverse operation;Through the above operations, the positioning device is realized by reducing the use of bolts, and under the premise of ensuring firm fixation, the staff can fix and disassemble the double integral casting guide blades conveniently and quickly; the above is the fixing operation of the double blade 7, and the general operation of processing the air film hole in the blocked part of the double blade 7 is as follows: place the positioning device of the present application on the magnetic platform in the EDM forming machine, and use the lever micrometer to calibrate the positioning device, turn on the magnetic platform switch to fix the positioning device; use the EDM centering ball to convert the coordinate system of the relative position between the positioning device of the present application and the forming machine; install the electrode holder 8 on the EROW chuck of the EDM forming machine (EROWA chuck is a high-precision electrode clamping system designed for electrospark machining (EDM), developed by the Swiss EROWA company, and belongs to EROWA ITS (Integrated Tooling System) is a part of the system, which is widely used in automatic clamping and positioning of electrodes). Since the electrode holder 1 8 and the electrode holder 2 9 have a positional relationship with the reference hole 109 on the upper surface of the mounting column 106 during design and manufacturing, the positional relationship is converted to the equipment processing head before processing and then written into the program. The electrode pair is used to process the exhaust film hole of the double blade 7 through the avoidance feed trajectory path in the program. After the left part of the exhaust film hole of the double blade 7 is processed by the electrode holder 1 8 and the installed electrode pair, as shown; Figure 11 As shown, the electrode holder 1 8 is replaced with the electrode holder 2 9, and the remaining air film holes on the right side of the exhaust film hole are processed by a small amount of electrodes on the electrode holder 2 9, as shown in FIG. Figure 13 As shown, the reason why two clamps are used for processing is that there are a large number of exhaust film holes. If a single clamp is used for processing, there is a risk that other parts of the clamp will hit the blade and cause damage. Therefore, the exhaust film holes are split into two parts and then divided into two clamps for processing. When the double blades 7 have multiple rows of blocked air film holes, the same design idea is adopted to design and manufacture clamps corresponding to different rows, so that the processing of multiple rows of air film holes in the blocked parts can be achieved.
