Description

Technical Field

[0001] This utility model relates to the field of detection device technology, specifically a high-precision detection device for general blade processing. Background Technology

[0002] Turbine blades are a crucial component of the turbine section in a gas turbine engine. The high-speed rotating blades are responsible for drawing high-temperature, high-pressure airflow into the combustor to maintain engine operation. To ensure stable long-term operation under extreme high-temperature and high-pressure conditions, turbine blades are often forged from high-temperature alloys and cooled using various methods, such as internal airflow cooling, boundary layer cooling, or thermal barrier coatings to protect the blades and ensure operational reliability. After turbine blade production, they need to be inspected to ensure they meet usage standards. Traditional inspection devices are mostly designed for specific blade models, resulting in a limited inspection range. To improve this and expand the inspection range, a high-precision inspection device for general-purpose blade processing is proposed.

[0003] For example, the detection device for high-precision workpiece processing disclosed in the authorization announcement number CN111023945B includes a base, a dragging mechanism is laterally slidably installed in the middle of the top plane of the base, and a workpiece is placed on the dragging mechanism;

[0004] Although it achieves the goal of having a drag rod fixedly installed on the left side wall of the drag mechanism, and concave receiving grooves on the front and rear side walls of the drag mechanism, with pulleys evenly spaced and rotatably installed in the receiving grooves, and the outer ends of the pulleys tangent to the inner wall of the rail, allowing the drag mechanism to slide along the rail, and reducing friction during sliding to prevent the drag mechanism from getting stuck, thus ensuring measurement accuracy and smoothness; however, it does not solve the problem that existing detection devices are not conducive to convenient linkage center positioning and clamping of turbine blades during use, and are not conducive to flexible adjustment of the flaw detection position, affecting the flexibility of detection and the convenience of turbine blade assembly and disassembly. Utility Model Content

[0005] The purpose of this invention is to provide a high-precision inspection device for general-purpose blade processing, in order to solve the problems mentioned in the background art, such as the inconvenience of convenient linkage center positioning and clamping of turbine blades, the difficulty in flexibly adjusting the flaw detection position, and the impact on the flexibility of inspection and the convenience of disassembling and assembling turbine blades.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a high-precision inspection device for general-purpose blade processing, comprising a placement seat and a limiting ring. The limiting ring is installed at the top of the placement seat, and a bearing seat is installed at the center of the top of the placement seat. A toothed ring is movably installed inside the limiting ring. A drive motor is installed on the outer wall of the placement seat, and a drive shaft is installed at the output end of the drive motor. A gear is fitted on the surface of the drive shaft, and the gear meshes with the toothed ring. Electric push rods are symmetrically installed at the top of the toothed ring, and push arms are installed at the output ends of the electric push rods. An integrated frame is provided above the toothed ring, and the integrated frame is connected to the push arms. A lead screw is movably installed inside the integrated frame, and a threaded sleeve is fitted on the surface of the lead screw, and the threaded sleeve is threadedly connected to the lead screw. A flaw detector is installed on the side wall of the threaded sleeve.

[0007] Preferably, a servo motor is mounted on the side wall of the integrated frame, and the output end of the servo motor is connected to the lead screw.

[0008] Preferably, a cylinder is installed at the bottom end of the bearing seat, and a moving rod is installed at the output end of the cylinder, and the moving rod is slidably connected to the bearing seat.

[0009] Preferably, the bearing seat has three sets of upper linkage rods with equal spacing inside, and each upper linkage rod has a limit shaft on its side wall, and the upper linkage rod is movably connected to the bearing seat through the limit shaft.

[0010] Preferably, the outer wall of the support seat is provided with three sets of clamping arms at equal intervals, and each clamping arm is provided with a linkage shaft on its side wall, and the clamping arm is movably connected to the support seat through the linkage shaft.

[0011] Preferably, each of the bearing seats below the upper linkage rod is provided with a lower linkage rod, and the lower linkage rod is slidably connected to the moving rod and slidably connected to the bearing seat.

[0012] Preferably, the clamping arm is slidably connected to the upper linkage rod, and the lower linkage rod is slidably connected to the clamping arm.

[0013] Compared with the prior art, the beneficial effects of this utility model are: the detection device not only realizes convenient linkage center positioning clamping and fixing of turbine blades, which facilitates flexible adjustment of the flaw detection position, but also improves the flexibility of detection and the convenience of disassembling and assembling turbine blades.

[0014] (1) The electric push rod drives the integrated frame and flaw detector upward through the push arm, so that the center position of the turbine blade is placed outside the clamping arm. The cylinder drives the moving rod to move upward, and the moving rod drives the upper linkage rod to rotate and move around the limit shaft. The upper linkage rod drives the clamping arm to rotate around the linkage shaft, so that the clamping arm contacts the inner wall of the turbine blade, thereby clamping and fixing the center of the turbine blade on the placement seat. Then, the electric push rod is opened in the reverse direction, and the electric push rod drives the integrated frame and flaw detector to reset, so that the flaw detector is close to the turbine blade. The flaw detector is opened and the flaw detector is used to inspect the inside of the turbine blade to detect flaws. To check for internal cracks, after inspection, the cylinder is reversed and opened. The cylinder drives the moving rod to reset, which in turn moves the lower linkage rod outward. The lower linkage rod then drives the clamping arm to rotate around the linkage shaft to reset, moving the clamping arm away from the center of the turbine blade, thus allowing the turbine blade to be removed. When the flaw detector's detection position needs to be adjusted laterally, the servo motor drives the lead screw to rotate. The lead screw, through the threaded sleeve, moves the flaw detector laterally, thus adjusting the flaw detector's detection position laterally. This achieves convenient linkage center positioning and clamping of the turbine blade, facilitating the movement and adjustment of the flaw detection position. The drive motor drives the gear to rotate through the drive shaft. The gear drives the gear ring to rotate inside the limit ring. The gear ring drives the electric push rod, push arm, integrated frame, threaded sleeve, and flaw detector to rotate, thus circumferentially adjusting the flaw detector's detection position. This allows for inspection of the turbine blade from different positions, improving the flexibility of the inspection. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0021] Please see Figure 1-5 This utility model provides an embodiment of a high-precision inspection device for general-purpose blade processing, including a placement seat 1 and a limiting ring 6. The limiting ring 6 is installed at the top of the placement seat 1, and a bearing seat 13 is installed at the center of the top of the placement seat 1. A toothed ring 5 is movably installed inside the limiting ring 6. A drive motor 2 is installed on the outer wall of the placement seat 1, and the drive motor 2 provides power driving. A drive shaft 3 is installed at the output end of the drive motor 2. A gear 4 is fitted on the surface of the drive shaft 3, and the gear 4 meshes with the toothed ring 5. Electric push rods 7 are symmetrically installed at the top of the toothed ring 5, and the electric push rods 7 provide power driving. Push arms 8 are installed at the output ends of the electric push rods 7. An integrated frame 9 is provided above the toothed ring 5, and the integrated frame 9 is connected to the push arms 8. A lead screw 12 is movably installed inside the integrated frame 9. A threaded sleeve 10 is fitted on the surface of the lead screw 12, and the threaded sleeve 10 is threadedly connected to the lead screw 12. A flaw detector 11 is installed on the side wall of the threaded sleeve 10.

[0022] Open the electric push rod 7, which, via the push arm 8, moves the integrated frame 9 and the flaw detector 11 upwards, positioning the center of the turbine blade around the clamping arm 14. Open the cylinder 15, which moves the moving rod 17 upwards. The moving rod 17 then rotates and moves the upper linkage rod 18 around the limit shaft 19, causing the clamping arm 14 to rotate around the linkage shaft 20, bringing it into contact with the inner wall of the turbine blade and clamping and fixing the center of the turbine blade onto the placement seat 1. Then, open the electric push rod 7 in the reverse direction, which resets the integrated frame 9 and the flaw detector 11, bringing the flaw detector 11 closer to the turbine blade. Open the flaw detector 11 (model Victory VC855A, similar to this product), which is used to inspect the interior of the turbine blade. The flaw detector 11 is used to detect internal cracks. After the inspection is completed, the cylinder 15 is opened in the reverse direction, and the cylinder 15 drives the moving rod 17 to reset. The moving rod 17 drives the lower linkage rod 21 to move outward, and the lower linkage rod 21 drives the clamping arm 14 to rotate and reset around the linkage shaft 20, so that the clamping arm 14 is away from the center position of the turbine blade, thereby removing the turbine blade. When it is necessary to adjust the detection position of the flaw detector 11 laterally, the servo motor 16 is turned on, and the servo motor 16 drives the lead screw 12 to rotate. With the lead screw 12 and the threaded sleeve 10 connected by threads, the lead screw 12 drives the flaw detector 11 to move laterally through the threaded sleeve 10, thereby adjusting the detection position of the flaw detector 11 laterally. This realizes convenient linkage center positioning clamping and fixing of the turbine blade, and facilitates the movement and adjustment of the flaw detection position.

[0023] A servo motor 16 is installed on the side wall of the integrated frame 9. The servo motor 16 plays the role of power drive, and the output end of the servo motor 16 is connected to the lead screw 12. A cylinder 15 is installed at the bottom of the bearing seat 13. The cylinder 15 plays the role of power drive, and a moving rod 17 is installed at the output end of the cylinder 15. The moving rod 17 is slidably connected to the bearing seat 13.

[0024] The bearing seat 13 is provided with three sets of upper linkage rods 18 at equal intervals. Each upper linkage rod 18 has a limit shaft 19 on its side wall, and the upper linkage rod 18 is movably connected to the bearing seat 13 through the limit shaft 19.

[0025] The outer wall of the bearing seat 13 is provided with three sets of clamping arms 14 at equal intervals. Each clamping arm 14 is provided with a linkage shaft 20 on its side wall. The clamping arm 14 is movably connected to the bearing seat 13 through the linkage shaft 20. The bearing seat 13 below the upper linkage rod 18 is provided with a lower linkage rod 21. The lower linkage rod 21 is slidably connected to the moving rod 17 and to the bearing seat 13.

[0026] The clamping arm 14 is slidably connected to the upper linkage rod 18, and the lower linkage rod 21 is slidably connected to the clamping arm 14;

[0027] Turn on the drive motor 2, which drives the gear 4 to rotate via the drive shaft 3. With the movable cooperation between the gear ring 5 and the limiting ring 6, and the mutual meshing of the gear 4 and the gear ring 5, the gear 4 drives the gear ring 5 to rotate inside the limiting ring 6. The gear ring 5 drives the electric push rod 7, the push arm 8, the integrated frame 9, the threaded sleeve 10, and the flaw detector 11 to rotate, thereby adjusting the detection position of the flaw detector 11 in a circular motion, so as to inspect the turbine blade from different positions and improve the flexibility of the inspection. Working principle: The electric push rod 7 drives the integrated frame 9 and the flaw detector 11 to move upward via the push arm 8, placing the center position of the turbine blade outside the clamping arm 14. The cylinder 15 drives the moving rod 17 to move upward, which in turn drives the upper linkage rod 18 to rotate and move around the limit shaft 19. The upper linkage rod 18 drives the clamping arm 14 to rotate around the linkage shaft 20, so that the clamping arm 14 contacts the inner wall of the turbine blade, thus clamping and fixing the center of the turbine blade onto the placement seat 1. Then, the electric push rod 7 is opened in the reverse direction, which drives the integrated frame 9 and the flaw detector 11 to reset, bringing the flaw detector 11 close to the turbine blade. The flaw detector 11 then inspects the inside of the turbine blade to detect the presence of cracks. After the inspection is completed, the cylinder 15 is opened in the reverse direction, which drives the moving rod 17 to reset. The moving rod 17 then drives the lower linkage rod 21 outward. The movement is achieved by the lower linkage rod 21 driving the clamping arm 14 to rotate and reset around the linkage shaft 20, thereby moving the clamping arm 14 away from the center position of the turbine blade and removing the turbine blade. When it is necessary to adjust the detection position of the flaw detector 11 laterally, the servo motor 16 drives the lead screw 12 to rotate, and the lead screw 12 drives the flaw detector 11 to move laterally through the threaded sleeve 10, thereby adjusting the detection position of the flaw detector 11 laterally. The drive motor 2 drives the gear 4 to rotate through the drive shaft 3, and the gear 4 drives the gear ring 5 to rotate inside the limit ring 6. The gear ring 5 drives the electric push rod 7, push arm 8, integrated frame 9, threaded sleeve 10 and flaw detector 11 to rotate, thereby circumferentially adjusting the detection position of the flaw detector 11, so as to inspect the turbine blade from different positions and improve the flexibility of inspection. The above is the complete usage of the high-precision inspection device for general blade processing.
