Description

Technical Field

[0001] This utility model relates to the field of positional accuracy detection technology, specifically a positional accuracy detection device for the sealing groove of a double-unit integral cast blade. Background Technology

[0002] Twin-section integral cast blades, also known as twin-section guide vanes, are important components of gas turbines and aero engines. They typically consist of a blade body and upper and lower edge plates on both sides of the blade body. Their unique curved structure can change the direction of gas flow and guide the high-temperature gas flow. When the guide vanes are working, they are surrounded by high-temperature gas flow. To reduce gas leakage losses in aero engines and improve sealing performance, sealing grooves need to be machined on the working blades. Since the sealing grooves directly determine the installation accuracy and sealing effect of the sealing strip, if the position is off, the sealing strip will not fit properly, gas leakage will occur, resulting in thrust loss and increased fuel consumption. Therefore, the position of the sealing grooves needs to be checked.

[0003] Currently, the sealing grooves on double-linked guide vanes are typically opened at specific angles on the side plates of the blade base and blade back. Although this inclined structure can meet the aerodynamic sealing requirements, it results in the sealing grooves on both sides being spatially asymmetrical and non-coplanar. Consequently, it is very difficult to use a single device to simultaneously detect the position of the sealing grooves on both sides of the blade in a single clamping. Existing detection methods often require multiple sets of fixtures or step-by-step processes to position and measure the base side and back side separately. This not only accumulates large clamping errors and occupies a lot of equipment, but also, because the blade itself is a spatial torsional curved surface, any slight angle adjustment will cause the grooves on both sides to deviate from the theoretical coordinates simultaneously, affecting the detection efficiency and resulting in relatively poor detection accuracy. Therefore, based on the above problems, a device for detecting the position of the sealing grooves on double-linked integrally cast blades is proposed. Utility Model Content

The clamping block one, clamping block two, locking part and positioning block can cooperate with the seat to accurately install and reliably fix the double blades. At this time, the operator can push each probe on both sides to move towards the double blades and observe whether it can be smoothly inserted into the sealing groove. This will determine whether the position of the sealing groove meets the design tolerance. If a probe is blocked and cannot be inserted, it indicates that there is a positional deviation in the groove, and the subsequent processing technology needs to be adjusted immediately. This enables the sealing groove position detection device to accurately detect the position of the sealing grooves on both sides of the double blades in one clamping, thereby improving detection efficiency and accuracy.

This realizes that the sealing groove position detection device can quickly and efficiently perform automated position detection of the sealing groove of the double blade, solving the problem of low efficiency caused by the previous manual insertion of probes into the sealing groove of the double blade one by one.

[0036] Please see Figure 1-13This utility model provides a technical solution:

[0037] A device for detecting the position of a double-unit integral cast blade sealing groove includes a base 1, which includes a base plate 101. A positioning seat 102 is fixedly connected to the front-middle groove on the top of the base plate 101. The inner side of the positioning seat 102 has a through-hole 104. A positioning seat 203 is fixedly connected to the rear-middle groove on the top of the base plate 101. A back-side needle guide block 105 is fixedly connected to the front-left groove on the top of the base plate 101. A back-side needle guide block 206 is fixedly connected to the rear-left groove on the top of the base plate 101. The inner sides of both the back-side needle guide block 105 and the back-side needle guide block 206 have mounting grooves of different sizes. 107, and all mounting slots 107 are right-opening. A basin-side needle guide block 108 is fixedly connected to the right front side groove at the top of the base plate 101, and a basin-side needle guide block 209 is fixedly connected to the right rear side groove at the top of the base plate 101. Several through needle guide holes 110 are opened on the inner sides of the back-side needle guide block 105, the back-side needle guide block 206, the basin-side needle guide block 108, and the basin-side needle guide block 209. A positioning ring sleeve 111 is provided on the outer side of each needle guide hole 110. A double blade 9 is provided between the back-side needle guide block 105 and the basin-side needle guide block 108. The back-side needle guide block 105, the back-side needle guide block 206, and the basin-side needle guide block 109 are all fixedly connected. Both the end face of the needle guide block 108 and the side needle guide block 109 away from the double blade 9 are fixedly connected to the positioning ring sleeve 111. The end face of the positioning ring sleeve 111 away from the double blade 9 is provided with a pair of notches 112. A probe 6 is provided inside the needle guide hole 110. Several bolt holes are provided inside the positioning seat 102 and the positioning seat 103. A pair of clamping blocks 12 are detachably connected to the upper side of the positioning seat 102 by bolts. A pair of clamping blocks 23 are detachably connected to the upper side of the positioning seat 103 by bolts. Positioning blocks 5 of the same size are fixedly connected to the inner side of the mounting grooves 107 of different sizes. This arrangement ensures that the clamping blocks 12... The clamping block 2 3 can be disassembled as needed; a locking part 4 is provided on the upper side of the base plate 101. The locking part 4 includes a base strip 41 fixed to the front side of the positioning seat 102. A threaded hole 42 is opened on the inner side of the base strip 41, which is located on the front side of the rail opening 104 and is through the hole. An adjusting bolt 43 is threadedly connected to the inner side of the threaded hole 42. A locking member 45 is slidably connected to the inner side of the rail opening 104. A mating groove 46 is opened on the front side of the locking member 45. A linkage 44 that is rotatably connected to the rear end of the adjusting bolt 43 is fixedly connected to the adjusting bolt 44. Through this setting, the locking member 45 can be adjusted in position by rotating the adjusting bolt 43 as needed by the operator.Both positioning base 102 and positioning base 2 103 have mating grooves of different sizes on their upper sides. These grooves fit snugly against the lower edge of the double-bladed blade 9. This arrangement ensures that the lower edge of the double-bladed blade 9 fits seamlessly against the mating grooves on the top of both positioning bases 102 and 103, serving as a reference for subsequent positioning of the double-bladed blade 9. The lower end faces of the corner blocks of clamping blocks 1 2 and 2 3 are tightly fitted against the front and rear edges of the double-bladed blade 9. The right end face of the positioning abutment block 5 fits snugly against the lower edge of the double-bladed blade 9. The left end faces are fitted together, allowing the positioning block 5 to serve as a reference for the subsequent positioning of the double-blade 9. The front end face of the rear protrusion of the locking component 45 is tightly fitted with the rear end face of the front plate of the double-blade 9, ensuring a secure fixation of the double-blade 9. Sealing grooves are provided on both the left and right sides of the double-blade 9, and needle guide holes 110 are located on both sides of the double-blade 9, aligned with the sealing grooves. This arrangement allows the needle guide holes 110 to guide the displacement of the probe 6, ensuring that the probe 6 is precisely positioned inside the sealing groove.

[0038] like Figures 1-3 , Figures 11-13As shown, a drive module 7 is installed on the rear side of the base 1. The drive module 7 includes an air supply shell 71 fixed to the rear side of the base plate 101. A charging / suction dual-purpose air pump 72 is fixedly connected to the upper end face of the middle shell of the air supply shell 71. A vent pipe 73 is fixedly connected to the right side of the charging / suction dual-purpose air pump 72 and is in communication with it. The lower end of the vent pipe 73 is fixedly connected to and communicates with the air supply shell 71. Several connecting hoses 75 are fixedly connected to and communicate with the air supply shell 71 on both the left and right sides. A drive connector 76 is installed at the end of each connecting hose 75 away from the air supply shell 71. The drive connector 76 includes components that connect to the connecting hose 75. A connecting pipe 761 is connected to a connecting hose 75. The end of the connecting pipe 761 furthest from the connecting hose 75 is connected to a conduit 762 sleeved on the outside of the probe 6. The conduit 762 is fixedly connected to the connecting pipe 761. Both the upper and lower sides of the conduit 762 are fixedly connected to locking pins 763 located inside the annular groove of the positioning ring 111. This arrangement allows the drive module 7 to simultaneously drive each probe 6 to move towards or away from the double-bladed blade 9, thereby improving the detection efficiency of the sealing groove position. The outer curved surface of the conduit 762 is close to the positioning ring 111. Several vent holes 764 are provided on each side. This arrangement allows the gas inside the guide tube 762 to be squeezed out and discharged when the probe 6 moves towards the double-bladed blade 9, preventing the gas pressure from affecting the displacement of the probe 6 within the guide tube 762. The size of the locking pin 763 is smaller than the size of the notch 112. This arrangement allows the locking pin 763 to disengage from the notch 112, enabling the drive connector 76 to disengage from the positioning ring 111. The probe 6 consists of a needle body and a circular push block. The diameter of the circular push block of the probe 6 is the same as the inner diameter of the guide tube 762. The inner wall of the guide tube 762 is the same as the inner diameter of the circular push block of the probe 6. The outer curved surface of the push block fits into place. This setting allows the charging and suction action of the dual-purpose air pump 72 to drive the probe 6 to move laterally. The upper side of the middle shell of the air supply shell 71 is fixedly connected to a pressure relief valve pipe 74 that communicates with its interior. This setting allows each probe 6 to be pushed and displaced by air pressure. After contacting the double blades 9, the excess airflow injected by the dual-purpose air pump 72 will be released through the pressure relief valve pipe 74, preventing damage to the probe 6 caused by continuously increasing air pressure. A controller 8 is installed on the upper side of the base plate 101. This setting allows the controller 8 to control the dual-purpose air pump 72.

[0039] Workflow: The sealing groove position detection device operates as follows to detect the sealing groove position of the double blade 9. Note: The dual-purpose air pump 72 for charging and suction in this application is externally powered and controlled by the controller 8. Installation operation of the double blade 9: First, completely remove the clamping block 1 2 and clamping block 2 3 from the positioning seat 1 102 and positioning seat 2 103. Then, rotate the adjusting bolt 43. With the help of its threaded engagement with the threaded hole 42, the adjusting bolt 43 will generate a backward axial displacement while rotating. This displacement is synchronously transmitted through the linkage 44, causing the locking part 45 to slide backward as a whole, thereby making sufficient placement space for the double blade 9. At this time, move the double blade 9 to be inspected to the positioning seat 1 102 and positioning seat 2 103. Above the second positioning seat 103, its lower edge is simultaneously and seamlessly fitted with the mating grooves on the top of the first positioning seat 102 and the second positioning seat 103, thus completing the initial engagement of the double blade 9 with the positioning seat; after the double blade 9 is correctly matched with the first positioning seat 102 and the second positioning seat 103, the right end face of the paired positioning blocks 5 on the left side will make tight contact with the left end face of the double blade 9, serving as a lateral reference; then the previously removed clamping blocks 12 and 23 can be re-fixed to the first positioning seat 102 and the second positioning seat 103 with bolts, so that the lower end faces of the clamping blocks of clamping blocks 12 and 23 press against the front and rear edges of the double blade 9 respectively, achieving the first engagement of the blade. Secondary constraint; finally, rotate the adjusting bolt 43 again, causing it to drive the linkage 44 and the locking member 45 to move forward synchronously until the front end face of the protrusion at the rear of the locking member 45 is completely in contact with the rear end face of the front plate of the double blade 9, forming the second and final locking and positioning, thus completing the precise installation and reliable fixation of the double blade 9 in the entire testing device; Testing operation: Start the charging and suction dual-purpose air pump 72 through the controller 8 and set its working mode to air charging. The charging and suction dual-purpose air pump 72 then continuously delivers compressed air to the air supply shell 71 through the air pipe 73. The air supply shell 71 then evenly distributes the airflow to each connecting hose 75, and then each connecting hose 75 synchronously delivers the gas to each drive connector 76; Drive connector After receiving the gas, the nozzle 761 of the head 76 immediately guides it into the conduit 762. As the gas pressure in the conduit 762 continuously increases, this pressure will push the probe 6 to extend precisely towards the double blade 9, guided by the needle guide hole 110. When all probes 6 arrive at their respective sealing grooves simultaneously through the above operations, it is only necessary to observe whether the probe body of the probe 6 can be smoothly inserted into the groove to determine whether the position of the sealing groove meets the design tolerance. If a probe 6 is blocked and cannot be inserted, it indicates that there is a positional deviation in the groove, and the subsequent processing technology needs to be adjusted immediately. After the test is completed, the charging and suction dual-purpose air pump 72 is switched to the suction mode, and the probes 6 are quickly returned to their initial positions under negative pressure through reverse suction.Through the above sequential operation, the sealing groove position detection device can quickly and efficiently perform automated position detection of the sealing groove of the double-blade 9, solving the problem of low efficiency caused by the previous manual insertion of the probe 6 into the sealing groove of the double-blade 9 by the staff one by one; Probe 6 replacement operation: When it is necessary to replace a probe 6, simply pinch the drive connector 76 on the outside of the probe 6 with your fingers and rotate it slowly. The rotation will drive the locking pin 763 to rotate synchronously in the annular groove of the positioning ring sleeve 111. When the locking pin 763 is rotated to be completely aligned with the preset notch 112 of the positioning ring sleeve 111, maintain this angle and push the drive connector 76 smoothly away from the double-blade 9, so that the locking pin 763 is completely aligned with the notch 112 of the positioning ring sleeve 111. 63 slides out along the axial direction of the notch 112, and the drive connector 76 completely disengages from the positioning ring 111 and the old probe 6. At this point, the old probe 6 can be gently pulled out along the axial direction of the needle guide hole 110. The new probe 6 is then inserted into the needle guide hole 110 in its original direction and reset. Finally, the drive connector 76 is moved back towards the double blade 9, so that the retaining pin 763 is aligned with the notch 112 again and moved into the annular groove of the positioning ring 111. Then, it is reset and rotated to disengage the retaining pin 763 from the notch 112, thus reliably restoring the connection between the drive connector 76 and the positioning ring 111, and placing the drive connector 76 on the outside of the new probe 6. The entire replacement process requires no auxiliary tools and can be completed with one hand.
