Description

Technical Field

[0014] (III) Beneficial Effects

[0015] Compared with the prior art, this utility model provides a fully automated fluorescent flaw detection device for turbine casting production, which has the following advantages:

[0016] Increase automation levels and reduce human intervention

[0017] The device, through the cooperation of a rotating mechanism (servo drive motor, gear transmission assembly) and an installation mechanism (positioning column, clamping block, rotating shaft), can automatically complete the 360° rotation of turbine castings without the need for manual disassembly or adjustment of the casting orientation. This completely solves the pain point of "manual flipping after inspecting one side", avoids manual operation errors and time consumption, and increases the automated inspection coverage to 100%.

[0018] Improve detection efficiency and effectiveness

[0019] The pushing mechanism (electric push rod, guide rod, sliding block) can drive the turbine casting to move smoothly along the guide trajectory inside the fluorescent flaw detection box. Combined with the automatic flipping function of the rotating mechanism, it can realize all-round flaw detection without dead angles on the surface and near the surface of the casting. At the same time, the precise speed control of the servo motor and the stable meshing of the gear transmission ensure the flipping accuracy of the casting.

[0020] Enhance the positioning stability of castings and ensure inspection accuracy.

[0021] In the installation mechanism, the positioning column is precisely matched with the positioning groove of the turbine casting through multiple sets of locking blocks. With the spring pin on the right side of the positioning column, the casting can be quickly clamped and fixed to prevent it from falling off, thus avoiding the casting from shaking during the inspection process. The auxiliary plate and the support plate together form a bidirectional support for the rotating shaft, reducing the deformation of the rotating shaft caused by radial force and further ensuring the coaxiality of the casting when it is flipped.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Please see Figure 1-6 A fully automatic fluorescent flaw detection device for turbine casting production includes a fluorescent flaw detection box 1 and a turbine casting body 2. The fluorescent flaw detection box 1 is provided with an installation mechanism, and the turbine casting body 2 is placed with the corresponding installation mechanism.

[0031] The installation mechanism also includes a positioning column 3, a locking block 4, a locking plate 5, a rotating shaft 6, and a support plate 7. A positioning groove 8 is provided on one side of the turbine casting body 2. A pushing mechanism is provided at the bottom of the support plate 7. The right side of the support plate 7 is rotatably connected to the left side of the corresponding rotating shaft 6 through a bearing. A locking plate 5 is provided on the right side of the rotating shaft 6. A positioning column 3 is provided on the right side of the locking plate 5. Locking blocks 4 are fixedly installed around the positioning column 3. Multiple sets of locking blocks 4 are slidably fitted with the corresponding turbine casting body 2 through the positioning groove 8. A rotating mechanism is provided on the left side of the rotating shaft 6.

[0032] It is worth noting that the drive motor 12, fluorescent flaw detection box 1, electric push rod 13, drive motor 12, and controller 19 used in this utility model are all existing devices, and the control methods and circuit connection methods of the above devices are all existing technologies. Furthermore, this utility model provides power to the above devices by connecting an external power source via wires.

[0033] When this device is in use

[0034] Step 1: Device Initialization and Preparation

[0035] Connect the power supply to the fluorescent flaw detection box 1, start the right controller 19, and complete the equipment self-test (check whether the electric push rod 13, drive motor 12, and bearing rotation are normal, and whether the guide rod 15 slides smoothly).

[0036] Parameters are set via controller 19: pushing speed of electric push rod 13, casting flipping angle, and dwell time in the flaw detection area;

[0037] Check the status of the installation mechanism: confirm that the locking block 4 on the positioning column 3 is unworn, the spring pin 18 is in normal elasticity, and the bearing connection between the auxiliary plate 17 and the rotating shaft 6 is not stuck.

[0038] Step 2: Turbine casting clamping and positioning

[0039] The operator aligns the positioning groove 8 of the turbine casting body 2 (the part to be tested) with the positioning post 3 of the mounting mechanism, and slides the fitting along the direction of the clamping block 4 until the end face of the casting is in contact with the clamping plate 5.

[0040] Press the spring pin 18 on the right side of the positioning column 3 to make the spring pin 18 pop out and lock the right end face of the casting, thus completing the anti-fall-off fixing of the casting; at this time, the casting achieves circumferential positioning through the cooperation of the locking block 4 and the positioning slide 8, and axial positioning through the spring pin 18.

[0041] Step 3: Move the casting to the flaw detection area

[0042] The push mechanism is activated by the controller 19: the output end of the electric push rod 13 pushes the sliding block 14 to move smoothly along the guide rod 15 (between the guide plates 16 arranged symmetrically at the front and rear);

[0043] The sliding block 14 drives the top support plate 7, the mounting mechanism and the turbine casting to move synchronously until the casting is completely inside the fluorescent flaw detection box 1 (which can be confirmed by the position sensor built into the controller 19 or by observing the observation window of the box).

[0044] The electric push rod 13 stops working, and the sliding block 14 is locked in the current position to ensure the stability of the casting position during the inspection process.

[0045] Step 4: Fully automated flaw detection (multi-faceted inspection)

[0046] First-side inspection: Fluorescent flaw detection chamber 1 starts the flaw detection function (such as ultraviolet lamp group, fluorescent penetrant spray and other supporting components, and runs according to the conventional fluorescent flaw detection process) to detect defects on the surface and near surface of the casting currently facing, and the detection data is transmitted to the controller 19 for storage in real time.

[0047] Automatic flipping of castings: After the first side inspection is completed, the controller 19 automatically starts the rotation mechanism: the output end of the drive motor 12 (servo motor) drives the drive gear 9 to rotate, the drive gear 9 meshes with the driven gear 10 for transmission, and the driven gear 10 drives the rotating shaft 6 to rotate synchronously;

[0048] The rotating shaft 6 drives the mounting mechanism and turbine casting to flip the auxiliary plate 17 at a preset angle. The bearing supports the middle part of the rotating shaft 6 to prevent the shaft from shaking during rotation.

[0049] Subsequent surface inspection: After the casting is flipped to the target angle, the drive motor 12 stops working, and the fluorescent flaw detection box 1 performs flaw detection on the surface of the casting facing the new direction. The "detection-flipping" process is repeated until all surfaces of the casting to be inspected have been inspected.

[0050] Step 5: Inspection completed and casting removed

[0051] After all surfaces are inspected, the controller 19 starts the push mechanism: the electric push rod 13 drives the sliding block 14 to move in the opposite direction, moving the mounting mechanism and turbine casting out of the fluorescent flaw detection box 1 to the part removal position;

[0052] The operator presses the spring pin 18 on the right side of the positioning column 3 to release the axial fixation of the casting, slides the casting in the opposite direction along the positioning column 3, so that the casting is disengaged from the cooperation between the locking block 4 and the positioning slide groove 8, and completes the removal of the casting.

[0053] Turn off the power to the controller 19 and the equipment, and clean the residual impurities (such as residual penetrant) on the surface of the positioning column 3 and the card block 4 to prepare for the next batch of inspections. At the same time, the data such as the casting number, defect location, and inspection time of this inspection can be exported through the controller 19 to facilitate quality traceability.

[0054] In practical use, it was found that it was inconvenient to adjust the rotation of the rotating shaft 6. To solve the above problem, in this embodiment, the rotating mechanism also includes a driving gear 9, a driven gear 10, a gear cover 11, and a drive motor 12. The gear cover 11 is provided on the left side of the support plate 7. The driving gear 9 and the driven gear 10 are provided inside the gear cover 11. The driving gear 9 and the driven gear 10 mesh with each other. The driven gear 10 is fixedly connected to the corresponding rotating shaft 6. The drive motor 12 is provided on the gear cover 11. The output end of the drive motor 12 is fixedly connected to the driving gear 9. The drive motor 12 is set as a servo motor.

[0055] In actual use, it was found that it was inconvenient to adjust the sliding block 14 by pushing it back and forth, and it was also inconvenient to install and inspect the turbine casting body 2. In order to solve the above problems, in this embodiment, the pushing mechanism also includes an electric push rod 13, a sliding block 14, a guide rod 15 and a guide plate 16. The guide plates 16 are symmetrically arranged at the bottom of the fluorescent inspection box 1. The guide rod 15 is arranged between the guide plates 16. The bottom end of the support plate 7 is fixedly connected to the top end of the corresponding sliding block 14. The sliding block 14 and the corresponding guide rod 15 are slidably fitted together. The rear side of the sliding block 14 is connected to the output end of the electric push rod 13. The mounting end of the electric push rod 13 is connected to the rear side of the fluorescent inspection box 1.

[0056] In actual use, it was found that it was not convenient to rotate the shaft 6 stably. In order to solve the above problem, this embodiment also includes an auxiliary plate 17. An auxiliary plate 17 is provided on the right side of the top of the sliding block 14. The auxiliary plate 17 is rotatably connected to the middle of the corresponding rotating shaft 6 through a bearing.

[0057] In actual use, it was found that it was not convenient to prevent the turbine casting body 2 from slipping. In order to solve the above problem, this embodiment also includes a spring pin 18, and a spring pin 18 is provided on the right side of the positioning post 3.

[0058] As a preferred embodiment of the above, a controller 19 is also included. The controller 19 is provided on the right side of the fluorescent flaw detection box 1, and the controller 19 controls and adjusts the corresponding electric push rod 13 and drive motor 12.

[0059] Easy to operate and highly practical

[0060] The device controls the electric push rod 13 (casting movement) and the drive motor 12 (casting flipping) in a unified manner through the controller 19. Parameters such as moving distance, flipping angle, and flaw detection dwell time can be set through the touch screen, eliminating the need for frequent adjustments by professional personnel. The sliding fit structure of the guide rod 15 and the sliding block 14, as well as the rotating components connected by bearings, are easy to maintain and have a low failure rate, reducing equipment operation and maintenance costs. It is suitable for continuous production inspection scenarios of batch turbine castings (such as blades and turbine disks).

[0061] Compact structure, wide adaptability

[0062] All components of the device (installation mechanism, rotation mechanism, and push mechanism) are integrated into the fluorescent flaw detection box 1; the spacing between the locking blocks 4 of the positioning column 3 and the moving stroke of the sliding block 14 can be finely adjusted by the controller 19, which significantly expands the applicable range.
