Description

Technical Field

[0001] This utility model relates to the field of nondestructive testing technology, and in particular to a tooling for scanning engine casing. Background Technology

[0002] The engine casing is one of the core components of an engine. During long-term storage and use, the engine casing is subjected to external forces such as heat, force, and sudden impacts, resulting in varying degrees of wear, damage, or cracks, which can lead to product failure. Therefore, non-destructive testing (NDT) technology is used to inspect engine casings, as this inspection is the foundation and prerequisite for engine remanufacturing. NDT technology is a technique that detects internal and surface defects in various engineering materials, components, and structural parts by utilizing changes in the thermal, acoustic, optical, electrical, and magnetic responses caused by abnormalities or defects in the internal structure of the material, without damaging the object being inspected. X-ray inspection equipment is one of the commonly used NDT methods. Industrial CT, based on the imaging principle of X-ray inspection equipment, is a computed tomography imaging technology. Engine casings are mostly made of aluminum alloy, and their large size, uneven wall thickness, and extremely complex structure necessitate the use of industrial CT tomography imaging technology to accurately determine engine failure conditions. The location and size of defects are then determined by observing the CT scan images, providing a basis for subsequent remanufacturing. In the existing technology, when inspecting the engine casing, the engine casing needs to be hoisted one by one to the front of the CT machine. Since the engine casing is large, it is inconvenient to fix it in the longitudinal direction. Moreover, after the engine casing is installed in place, if other parts need to be scanned, the position of the engine casing or the CT machine needs to be manually adjusted. The operation is complicated, the overall inspection time is long, and the inspection efficiency is low.

[0003] Therefore, there is an urgent need for a tooling for scanning engine casings to solve the above problems. Utility Model Content

[0051] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0052] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0053] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0054] In the description of this embodiment, the terms "upper," "lower," "left," and "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used solely for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more. Furthermore, the terms "first" and "second" are merely used for descriptive distinction and have no special meaning.

[0055] like Figures 1 to 10As shown, this embodiment provides a tooling for scanning an engine housing. The tooling includes a base frame 1, a tilting frame 2, a drive mechanism 4, and at least one clamping mechanism 3. The tilting frame 2 is rotatably connected to the base frame 1 about a first direction as an axis. The first direction is parallel to the plane where the base frame 1 is located. The tilting frame 2 includes a bottom beam 21 and a top beam 22 arranged opposite to each other. Each clamping mechanism 3 includes a rotating base 31 and a clamping assembly. The rotating base 31 is rotatably disposed on the bottom beam 21. The clamping assembly includes a first drive member 32 and a rotating top seat 33. The first drive member 32 is disposed on the top beam 22. The rotating top seat 33 is rotatably connected to the drive end of the first drive member 32. The first drive member 32 can drive the rotating top seat 33 to approach or move away from the rotating base 31 to clamp the engine housing 100 placed between the rotating base 31 and the rotating top seat 33. The drive mechanism 4 drives the rotating base 31 to rotate the rotating base 31 about its own axis. When the engine housing 100 needs to be inspected, it is transported between the rotating top mount 33 and the rotating base 31 by means of hoisting or other methods. Then, the first driving component 32 drives the rotating top mount 33 to approach the rotating base 31 until the rotating top mount 33 clamps the engine housing 100. Next, the tilting frame 2 is rotated so that it stands upright relative to the base frame 1, ensuring that the tilting frame 2 is directly facing the scanner, thus aligning the engine housing 100 with the scanner. The driving mechanism 4 then drives the rotating base 31 to rotate. Since the rotating top mount 33 is rotatably connected to the driving end of the first driving component 32, the rotation of the rotating base 31 causes the engine housing 100 and the rotating top mount 33 to rotate, adjusting the position of the engine housing 100 facing the scanner for comprehensive scanning and inspection. This engine housing scanning fixture helps save manpower and time, thereby improving overall inspection efficiency.

[0056] The first driving component 32 can be, but is not limited to, a screw jack, which can be electrically driven or manually driven, depending on actual needs. The rotating top seat 33 is rotatably connected to the output end of the screw jack via a rotary bearing, so that when the rotating base 31 rotates, causing the engine housing 100 to rotate, the rotating top seat 33 can rotate accordingly without interfering with the first driving component 32. Simultaneously, the first driving component 32 can smoothly drive the rotating top seat 33 to move along the length of the engine housing 100. Since the screw jack is a relatively mature existing technology, it will not be described in detail here.

[0057] In this embodiment, the tooling for scanning the engine housing also includes at least two housing placement racks 11. These racks are adjustablely positioned, parallel, and spaced apart. Each rack is parallel to the bottom beam 21 and the top beam 22. Each rack has at least one placement slot 110, in which the engine housing 100 can be positioned. The housing placement racks 11 provide support and positioning for the engine housing 100, allowing it to be hoisted and placed in the slots 110, thus stabilizing it between the rotating top seat 33 and the rotating base 31, facilitating subsequent clamping. Furthermore, multiple placement slots 110 can simultaneously position multiple engine housings 100, and multiple clamping mechanisms 3 can clamp multiple engine housings 100, facilitating simultaneous scanning and detection of multiple engine housings 100. The number of housing placement racks 11 is specifically determined according to actual needs; for example, three or four racks may be provided.

[0058] Optionally, the bottom surface of the housing placement rack 11 is provided with a clearance groove, which avoids the frame on the base frame 1, making it easy to place the housing placement rack 11 on the base frame 1; or the bottom surface of the housing placement rack 11 is provided with rollers 111, which makes it easy to move the housing placement rack 11, so that the housing placement rack 11 can be moved between the bottom beam 21 and the top beam 22 or moved out from between the bottom beam 21 and the top beam 22, which provides better ease of use.

[0059] like Figures 1 to 4 As shown, specifically, the tooling for scanning the engine housing also includes a drive cylinder 6. The drive cylinder 6 is rotatably connected to the base frame 1 about a first direction. The output end of the drive cylinder 6 is a retractable drive rod, the end of which is hinged to the tilting frame 2. The drive cylinder 6 drives the drive rod to extend, pushing the tilting frame 2 to rotate and stand upright relative to the base frame 1. The drive rod also provides support for the tilting frame 2, stabilizing it in a preset position. After scanning, the drive cylinder 6 drives the drive rod to retract, causing the tilting frame 2 to rotate back. This method saves time and effort and provides high safety for the engine housing 100.

[0060] Preferably, the distance between the top beam 22 and the bottom beam 21 is adjustable. Since the distance between the first driving member 32 and the rotating top seat 33 and the rotating base 31 is limited, adjusting the distance between the top beam 22 and the bottom beam 21 can accommodate different models of engine housing 100. When scanning and inspecting a smaller model of engine housing 100, the distance between the top beam 22 and the bottom beam 21 is reduced so that the first driving member 32 can smoothly clamp the engine housing 100 when driving the rotating top seat 33 to approach the rotating base 31. When scanning and inspecting a larger model of engine housing 100, the distance between the top beam 22 and the bottom beam 21 is increased so that the engine housing 100 can be placed between the top beam 22 and the bottom beam 21, and then the first driving member 32 is activated to drive the rotating top seat 33 to clamp the engine housing 100.

[0061] For example, the tilting frame 2 also includes a telescopic frame 23, which is connected between the top beam 22 and the bottom beam 21. The telescopic frame 23 includes at least one pair of connecting columns 232 and telescopic columns 231 that are slidably connected along the length of the engine housing 100. The length of the telescopic frame 23 can be adjusted by the relative sliding of the connecting columns 232 and the telescopic columns 231, thus adjusting the distance between the top beam 22 and the bottom beam 21. The adjustment of the slidably connected connecting columns 232 and the telescopic columns 231 is relatively smooth and convenient. In this embodiment, one of the connecting columns 232 and the telescopic columns 231 is provided with a slide rail 8, and the other is provided with a slider 9. The slide rail 8 and the slider 9 are slidably connected, realizing the sliding connection between the connecting columns 232 and the telescopic columns 231, making the overall length adjustment of the connecting columns 232 and the telescopic columns 231 relatively smooth.

[0062] Specifically, the tooling for scanning the engine housing also includes a third drive component 7. The third drive component 7 is mounted on the tilting frame 2 and drives the connecting telescopic column 231. The third drive component 7 can drive the telescopic column 231 to move along the length of the engine housing 100. By driving the telescopic column 231 to slide relative to the connecting column 232 through the third drive component 7, the total length of the telescopic column 231 and the connecting column 232 can be adjusted, thereby achieving the adjustment of the distance between the top beam 22 and the bottom beam 21, which is convenient, quick, and saves time and effort. The third drive component 7 can be, but is not limited to, a drive cylinder 6 or a lead screw mechanism, etc.

[0063] To better accommodate different models of engine housings 100, the rotating base 31 is rotatably connected to the base beam 21 via a first rotating shaft, and the rotating base 31 is detachably connected to the first rotating shaft; and / or the rotating top seat 33 is rotatably connected to the first driving component 32 via a second rotating shaft, and the rotating top seat 33 is detachably connected to the second rotating shaft. By assembling and disassembling rotating bases 31 and rotating top seats 33 of different specifications, different models of engine housings 100 can be better matched to achieve precise and stable clamping. For example, when scanning and inspecting a smaller engine housing 100, a smaller diameter rotating top seat 33 and rotating base 31 can be used, or when scanning and inspecting a larger engine housing 100, a larger diameter rotating top seat 33 and rotating base 31 can be used, making the tooling for scanning engine housings more practical.

[0064] For example, one end of the first rotating shaft is threaded, and a connecting shaft protrudes from the rotating base 31. The connecting shaft is also threaded. A nut 10 connects the threads on the first rotating shaft and the connecting shaft, achieving a detachable connection between the rotating base 31 and the first rotating shaft. This is simple, convenient, and low-cost. Similarly, the detachable connection method of the rotating top seat 33 is the same as that of the rotating base 31. Of course, in other embodiments, the detachable connection between the rotating base 31 and the first rotating shaft, and the detachable connection between the rotating top seat 33 and the second rotating shaft, can also be achieved in other ways, such as through plug-in connections.

[0065] Furthermore, such as Figures 7 to 10 As shown, when the engine housing 100 is erected by the tilting frame 2, and it is necessary to adjust the part of the engine housing 100 facing the scanner, adjustment is made by the drive mechanism 4. In this embodiment, the drive mechanism 4 includes a second drive member 41 and a transmission assembly 42. The second drive member 41 is mounted on the tilting frame 2, and the rotating base 31 is rotatably connected to the bottom beam 21 via a first rotating shaft. The transmission assembly 42 is drively connected to the second drive member 41 and the first rotating shaft, and the second drive member 41 drives the first rotating shaft to rotate via the transmission assembly 42. By driving the transmission assembly 42 to move through the second drive member 41, the first rotating shaft is rotated, thereby driving the rotating base 31 to rotate, realizing the rotation of the engine housing 100. This allows the scanner to perform a comprehensive circumferential scan and inspection of the engine housing 100, resulting in high inspection efficiency. It eliminates the need for manual movement of the engine housing 100 or the scanner, saving time and effort. The second drive member 41 can be, but is not limited to, a motor.

[0066] Specifically, the transmission assembly 42 includes a driving wheel 421, multiple driven synchronous pulleys 422, and multiple synchronous belts 423. The second driving member 41 drives and connects to the driving wheel 421, enabling the driving wheel 421 to rotate. At least one driven synchronous pulley 422 is provided on each first rotating shaft. The driven synchronous pulley 422 on the first rotating shaft closest to the second driving member 41 is connected to the driving wheel 421 via a synchronous belt 423. Each pair of adjacent driven synchronous pulleys 422 on the first rotating shaft is connected via a synchronous belt 423. By activating the second driving member 41, the driving wheel 421 is driven to rotate. The rotating wheel transmits power to the driven synchronous pulleys 422 via the synchronous belts 423, causing the driven synchronous pulleys 422 connected to the synchronous belts 423 to rotate, thereby driving the first rotating shaft to rotate and realizing the rotation of the rotating base 31. Furthermore, the multiple synchronous belts 423 connect each pair of adjacent driven synchronous pulleys 422 on the first rotating shaft, allowing the second driving member 41 to simultaneously drive all the first rotating shafts to rotate synchronously. Of course, in other embodiments, the synchronous belt 423 can also be replaced by a transmission gear, and the transmission is achieved by the meshing of the transmission gear with the driven synchronous pulley 422 and the driving pulley 421.

[0067] For example, four rotating bases 31 are provided on the bottom beam 21. The four rotating bases 31 are rotatably connected to the bottom beam 21 through four first rotating shafts. Two driven synchronous pulleys 422 are respectively provided on the three first rotating shafts closest to the driving wheel 421, and one driven synchronous pulley 422 is provided on the first rotating shaft far from the driving wheel 421. One driven synchronous pulley 422 on the first rotating shaft closest to the driving wheel 421 is connected to the driving wheel 421 through a synchronous belt 423. Another driven synchronous pulley 422 is connected to one driven synchronous pulley 422 on its adjacent first rotating shaft through a synchronous belt 423. And so on, one driven synchronous pulley 422 on each of every two adjacent first rotating shafts is connected through a synchronous belt 423, so as to realize the synchronous rotation of the four first rotating shafts, that is, to realize the synchronous detection of the four engine housings 100 at the same time, thereby improving the overall detection efficiency.

[0068] Preferably, the bottom beam 21 is hollow, and the transmission component 42 is located inside the bottom beam 21, which makes the appearance neater and more aesthetically pleasing, and avoids the transmission component 42 from being affected by the external environment, thus ensuring the stable operation of the drive mechanism 4.

[0069] In this embodiment, the tooling for scanning the engine housing also includes at least one tensioning assembly 5. Each tensioning assembly 5 includes a swing arm 51 and a tensioning wheel 52. One end of the swing arm 51 is rotatably connected to the bottom beam 21, and the tensioning wheel 52 is rotatably connected to the other end of the swing arm 51 and abuts against a synchronous belt 423. Specifically, the tensioning assembly 5 also includes a tensioning wheel seat, which is connected to the bottom beam 21, and one end of the swing arm 51 is hinged to the tensioning wheel seat. By the tensioning wheel 52 abutting against the synchronous belt 423, inward pressure is provided to one side of the synchronous belt 423, so that the synchronous belt 423 can be stably connected between the driving pulley 421 and the driven synchronous pulley 422 or two driven synchronous pulleys 422, preventing the synchronous belt 423 from loosening and falling off, and ensuring the working stability of the drive mechanism 4. Furthermore, the arrangement of the swing arm 51 allows the tensioning wheel 52 to have a certain swing space, so that the force on the synchronous belt 423 has a certain elasticity, preventing the synchronous belt 423 from breaking when the force is too large.

[0070] Preferably, such as Figure 1 As shown, the tooling for scanning the engine housing also includes a control panel 12 and a control module. The control panel 12 is mounted on the base frame 1. The first drive component 32, the second drive component 41 and the third drive component 7 are all electrically connected to the control module. The control panel 12 is equipped with control buttons, which control the start and stop of the first drive component 32, the second drive component 41 and the third drive component 7 as well as the working pressure.
