Description

Technical Field

[0001] This invention relates to the field of optical inspection technology, and more specifically, to an inspection device for engine compressor blades. Background Technology

[0002] In the process of testing new materials for engine compressor blades, optical methods, especially infrared light detection devices, have the advantages of being non-contact, real-time, covering the entire field, and highly sensitive. They can comprehensively evaluate the structural defects of new material engine compressor blades and determine whether the engine compressor blades are qualified products.

[0003] Among the existing publicly available technical documents, patent publication number CN108489984A discloses a detection device for aero-engine compressor blades. This technology involves a detection frame placed on a detection base, with one end of a connecting frame connected to the detection frame via a connecting block, and the other end connected to a connecting box via a connecting head. The connecting head is placed on the connecting box, which is positioned above a blade transfer device. A 3D scanner is placed inside the connecting box, and a remote control is electrically connected to the 3D scanner; a computing device is also electrically connected to the 3D scanner. The beneficial effects of this invention are: by detecting blades using instruments, human error is reduced, manpower input is reduced, and detection accuracy is increased. However, this technology still has the following problems.

However, there are irregular gaps between adjacent engine compressor blades, and the upper surface and both sides of each engine compressor blade are irregular curved surfaces.

It is difficult to simultaneously and multidimensionally inspect the irregular paths on the upper surface and both sides of the engine compressor blade based on the gap position of the engine compressor blade, which greatly reduces the inspection efficiency of engine compressor blades.

[0028] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] As attached Figure 1 - Appendix Figure 9 The invention relates to a detection device for engine compressor blades. The device is equipped with a multi-dimensional synchronous detection component. The multi-dimensional synchronous detection component enables the first infrared detection probe 6, the second infrared detection probe 8, and the third infrared detection probe 12 to work synchronously. This allows for synchronous multi-dimensional detection of the upper surface, the irregular curved path on the left side, and the irregular path on the right side of the blade 28, significantly improving detection efficiency. The specific structural configuration of the multi-dimensional synchronous detection component is as follows.

[0030] In this embodiment, as shown in the appendix Figure 1 - Appendix Figure 8As shown, the multi-dimensional synchronous detection component includes: an upper sleeve 3, slidably connected to the inner wall of the linkage frame 2, with a side sliding rod 4 on one side of the upper sleeve 3, and the side sliding rod 4 slidably connected to the linkage frame 2; an arc-shaped sleeve 5, fixedly connected to the bottom end of the side sliding rod 4, with a first infrared detection probe 6 fixedly connected to one side of the inner wall of the arc-shaped sleeve 5, and an arc-shaped guide rail 7 slidably connected to the outer wall of the arc-shaped sleeve 5; a second infrared detection probe 8, fixedly installed at the bottom end of the upper sleeve 3, with an upper curved track 9 slidably connected to the outer wall of the upper sleeve 3 and located on the lower surface of the linkage frame 2, the upper sleeve 3 being used to drive the second infrared detection probe 8 to move along the curved path of the inner wall of the upper curved track 9; and a side sleeve 10, located on the other side of the upper sleeve 3, slidably connected to the linkage frame 2, with a side curved track 11 slidably connected to the outer wall of the side sleeve 10, and a third infrared detection probe 12 slidably connected to the inner wall of the side curved track 11, the side sleeve 10 being used to drive the third infrared detection probe 12 to move along the curved path of the inner wall of the side curved track 11. Both the arc-shaped guide rail 7 and the upper curved track 9 are fixedly connected to the bracket 1, and the side curved track 11 is fixedly connected to the bracket 1. The side slide rod 4 is slidably connected to the arc-shaped guide rail 7, the linkage frame 2 is slidably connected to the upper curved track 9, and the third infrared detection probe 12 is fixedly connected to the side sleeve column 10; the first infrared detection probe 6 and the second infrared detection probe 8 are both electrically connected to the controller 24, and the third infrared detection probe 12 is electrically connected to the controller 24. So that when the linkage frame 2 moves to the right, it will drive the upper sleeve column 3 to move to the right. The upper sleeve column 3 will drive the rubber sleeve 14 to move along the outer wall of the curved column 15 in a curved path, so that the second infrared detection probe 8 can perform curved path movement detection on the upper surface of the blade 28. At the same time, when the linkage frame 2 moves to the right, it will drive the side sliding rod 4 to move to the right in sync. The arc sleeve 5 will move to the right along the outer wall of the guide rod 13, and the side sliding rod 4 will also move to the right along the inner wall of the arc guide rail 7. The arc sleeve 5 will drive the first infrared detection probe 6 to perform multi-dimensional movement detection on the right side of the blade 28. At the same time, when the linkage frame 2 moves to the right, it will drive the side sleeve column 10 to move to the right in sync. The side sleeve column 10 will drive the silicone sleeve 16 to move along the outer wall of the curved rod 17 in a curved path. The side sleeve column 10 will drive the third infrared detection probe 12 to perform curved path movement detection along the left side gap of the blade 28. In this way, synchronous multi-dimensional detection is achieved, which greatly improves the detection efficiency.

[0031] In this embodiment, as shown in the appendix Figure 4 As shown, a guide rod 13 is slidably connected to the inner wall of the arc-shaped sleeve 5. Both ends of the guide rod 13 are fixedly connected to the same arc-shaped guide rail 7 so that the arc-shaped sleeve 5 can move to the right along the outer wall of the guide rod 13. The guide rod 13 provides stable guidance for the arc-shaped sleeve 5, ensuring that the arc-shaped sleeve 5 moves along the specified path.

[0032] In this embodiment, as shown in the appendix Figure 6As shown, a rubber sleeve 14 is fixedly connected to the inner wall of the upper sleeve 3, and a curved column 15 is slidably connected to the inner wall of the rubber sleeve 14. Both ends of the curved column 15 are fixedly connected to the same upper curved track 9, so that the upper sleeve 3 can drive the rubber sleeve 14 to move along the outer wall of the curved column 15 in a curved path, ensuring that the upper sleeve 3 moves stably along the curved path.

[0033] In this embodiment, as shown in the appendix Figure 8 As shown, a silicone sleeve 16 is fixedly connected to the inner wall of the side sleeve column 10, and a curved rod 17 is slidably connected to the inner wall of the silicone sleeve 16. Both ends of the curved rod 17 are fixedly connected to the same side curved track 11, so that the side sleeve column 10 can drive the silicone sleeve 16 to move along the outer wall of the curved rod 17 in a curved path, ensuring that the side sleeve column 10 moves stably according to the specified curved path.

[0034] In this embodiment, as shown in the appendix Figure 1 - Appendix Figure 9 As shown, the top of the bracket 1 is provided with a linkage assembly, which includes: a support frame 18, fixedly connected to the top of the bracket 1, with a screw 19 rotatably mounted on the inner wall of the support frame 18; a sleeve 20, slidably connected to the inner wall of the support frame 18, with a threaded connection between the sleeve 20 and the screw 19, a fixed connection between the bottom end of the sleeve 20 and the linkage frame 2, and a slidable connection between the sleeve 20 and the support frame 18; and a drive motor 21, installed at one end of the support frame 18, which drives the screw 19 to rotate. The drive motor 21 is electrically connected to the controller 24 so that the controller 24 can start the drive motor 21 to ensure that the drive motor 21 drives the screw 19 to rotate. Under the action of the threaded transmission force, the sleeve 20 moves to the right along the inner wall of the support frame 18, stabilizing the sleeve 20 to guide it to move to the right, and the sleeve 20 drives the linkage frame 2 to move to the right stably.

[0035] In this embodiment, as shown in the appendix Figure 1 - Appendix Figure 9As shown, an electric cylinder 22 is mounted on the lower surface of the support frame 18. The electric cylinder 22 is electrically connected to the controller 24, and the output end of the electric cylinder 22 is fixedly connected to the support frame 18. A mounting plate 23 is fixedly connected to one side of the outer wall of the electric cylinder 22. A stepper motor 25 is mounted on the upper surface of the mounting plate 23 near its center point. A positioning seat 26 is fixedly connected to the output end of the stepper motor 25. A compressor shaft head 27 is placed on the inner wall of the positioning seat 26. Multiple blades 28 are fixedly connected to the outer wall of the compressor shaft head 27. The stepper motor 25 is used to drive the positioning seat 26 to rotate, and the stepper motor 25 is electrically connected to the controller 24. So that the stepper motor 25 can be started by the controller 24, so that the stepper motor 25 drives the positioning seat 26 to rotate the compressor shaft head 27. The compressor shaft head 27 drives the blades 28 to rotate. The electric cylinder 22 will drive the support frame 18 to move down. The bracket 1 drives the side curved track 11 to be located at the left gap position of the next blade 28, the arc guide rail 7 to be located at the right gap position of the next blade 28, and at the same time the upper curved track 9 is located above the next blade 28. In this way, the switching detection of multiple blades 28 is repeated.

[0036] The working principle of the engine compressor blade detection device of the present invention is as follows: First, during the installation of this invention, in the process of new material testing of multiple blades 28, the compressor shaft head 27 is placed on the inner wall of the positioning seat 26, and multiple blades 28 are supported by the compressor shaft head 27. One blade 28 is located below the linkage frame 2, while the second infrared detection probe 8 is located above the blade 28, the first infrared detection probe 6 is located on the right side of the blade 28, and the third infrared detection probe 12 is located on the left side of the blade 28.

[0037] Secondly, when the present invention is linked, the controller 24 starts the drive motor 21, the drive motor 21 drives the screw 19 to rotate, the screw 19 drives the socket 20 to move to the right under the action of the thread transmission force, the socket 20 moves to the right along the inner wall of the support frame 18, the socket 20 drives the linkage frame 2 to move to the right, at the same time the mounting plate 23 supports the electric cylinder 22, the output end of the electric cylinder 22 supports the support frame 18, the support frame 18 supports the bracket 1, the bracket 1 supports the upper curved track 9, the bracket 1 supports the arc guide rail 7, and the bracket 1 supports the side curved track 11, increasing the stability of the arc guide rail 7, the upper curved track 9 and the side curved track 11, ensuring that the socket 20 stably drives the linkage frame 2 to move to the right.

[0038] Simultaneously, during multi-dimensional synchronous detection, when the linkage frame 2 moves to the right, it drives the upper sleeve 3 to move to the right. The upper sleeve 3 slides on the linkage frame 2, and at the same time, the upper sleeve 3 drives the rubber sleeve 14 to move along the outer wall of the curved column 15 along a curved path. During this curved path movement, the rubber sleeve 14 undergoes deformation. The upper sleeve 3 is used to drive the second infrared detection probe 8 to move along the inner wall of the upper curved track 9 along a curved path, ensuring that the second infrared detection probe 8 performs curved path movement detection on the upper surface of the blade 28. When the distance value sensed by the second infrared detection probe 8 is different from the value set by the controller 24, there is a defect on the upper surface of the blade 28, and the detection data is unqualified. When the distance value sensed by the second infrared detection probe 8 is the same as the value set by the controller 24, there is no defect on the upper surface of the blade 28, and the detection data is qualified.

[0039] Simultaneously, as the linkage frame 2 moves to the right, it also drives the side slide rod 4 to move to the right. The side slide rod 4 drives the arc sleeve 5 to move to the right, and the arc sleeve 5 moves to the right along the outer wall of the guide rod 13. At the same time, the arc sleeve 5 moves to the right along the inner wall of the arc guide rail 7, and the side slide rod 4 also moves to the right along the inner wall of the arc guide rail 7. Thus, the arc sleeve 5 moves to the right along the inner wall of the arc guide rail 7, and the arc sleeve 5 drives the first infrared detection probe 6 to move to the right along the right side gap of the blade 28 for detection. The first infrared detection probe 6 performs multi-dimensional movement detection on the right side of the blade 28. When the distance value sensed by the first infrared detection probe 6 is different from the value set by the controller 24, there is a defect on the right side of the blade 28, and the right side of the blade 28 is in an unqualified state. When the distance value sensed by the first infrared detection probe 6 is the same as the value set by the controller 24, there is no defect on the right side of the blade 28, and the right side of the blade 28 is in a qualified state.

[0040] Simultaneously, the rightward movement of the linkage frame 2 causes the side sleeve column 10 to move synchronously to the right. The side sleeve column 10 slides along the linkage frame 2, and at the same time, it drives the silicone sleeve 16 to move along the outer wall of the curved rod 17 in a curved path. Simultaneously, the side sleeve column 10 guides the movement along the inner wall of the side curved track 11 in a curved path. Furthermore, the silicone sleeve 16 can deform during this curved path movement along the outer wall of the curved rod 17, ensuring that the side sleeve column 10 can move along the curved path on the outer wall of the curved rod 17. This causes the side sleeve column 10 to drive the third infrared detection probe 12 to move along a curved path, and the third infrared detection probe 12 detects this movement along the gap on the left side of the blade 28. When the distance value sensed by the third infrared detection probe 12 is different from the value set by the controller 24, there is a defect on the left side of the blade 28, and the left side of the blade 28 is considered unqualified. When the distance value sensed by the third infrared detection probe 12 is the same as the value set by the controller 24, there is no defect on the left side of the blade 28, and the left side of the blade 28 is in a qualified state. This allows for the detection of movement along a curved path on the upper surface of the blade 28, as well as the detection of movement along a curved path on the left side of the blade 28 and the detection of movement along a multi-dimensional path on the right side of the blade 28.

[0041] Finally, during the linkage switching of this invention, after the detection is completed, the controller 24 starts the electric cylinder 22. The output end of the electric cylinder 22 pushes the support frame 18 upward, the support frame 18 drives the bracket 1 upward, the bracket 1 drives the side curved track 11 upward, and at the same time, the bracket 1 drives the upper curved track 9 upward, and the bracket 1 drives the arc-shaped guide rail 7 upward. In this way, both the side curved track 11 and the arc-shaped guide rail 7 create a large gap with the blade 28. Then, the controller 24 starts the stepper motor 25, the stepper motor 25 drives the positioning seat 26 to rotate, and the positioning seat 26 drives the compressor shaft head. 27 rotates, the compressor shaft head 27 drives the blade 28 to rotate, and the next blade 28 is located below the upper curved track 9. At the same time, the controller 24 starts the electric cylinder 22, the electric cylinder 22 drives the support frame 18 to move down, the support frame 18 drives the bracket 1 to move down, the bracket 1 drives the side curved track 11 to be located at the left gap position of the next blade 28, the arc guide rail 7 is located at the right gap position of the next blade 28, and at the same time the upper curved track 9 is located above the next blade 28, and the next blade 28 continues to be synchronously multi-dimensionally detected.
