Description

Technical Field

[0001] This utility model relates to the field of graphite crucible surface inspection technology, and specifically discloses an auxiliary device for detecting defects on the surface of graphite crucibles. Background Technology

[0002] Graphite crucibles, as important high-temperature resistant containers, are widely used in metallurgy, chemical industry, and new materials. With increasingly stringent requirements for product quality in industrial production, the inspection of graphite crucible surface quality is becoming more rigorous. Surface defects such as cracks, pores, scratches, and dents not only affect the appearance of the crucible but can also become stress concentration points during high-temperature use, leading to crucible breakage and seriously impacting production safety and product quality.

[0003] Currently, the detection of surface defects in graphite crucibles mainly relies on manual visual inspection or image acquisition and analysis using industrial cameras. However, existing online crucible surface inspection devices cannot simultaneously inspect the inner and outer surfaces of the crucible, resulting in low inspection efficiency. They are also easily constrained by size, cup shape, and height, making inspection inconvenient. Furthermore, the bottom of the crucible, serving as a support surface, is often obscured by the inspection platform, making it difficult to effectively identify bottom defects. When bottom inspection is required, the crucible needs to be flipped, which poses a risk of scratching the surface. Therefore, existing inspection devices are mostly designed for single surfaces, failing to achieve continuous, efficient, and comprehensive inspection of the outer wall, inner wall, and bottom of the crucible at the same station. This leads to a fragmented inspection process, low overall inspection efficiency, and the risk of missed defects. Utility Model Content

[0004] The purpose of this utility model is to provide an auxiliary device for detecting surface defects in graphite crucibles. It can effectively solve the technical problem that it is difficult to comprehensively and efficiently detect the outer wall, inner wall and bottom of graphite crucibles during the surface defect detection process, improve the integrity and automation level of the detection, and meet the high standard requirements of modern industrial production for product quality control.

[0005] This utility model is achieved through the following technical solution: An auxiliary device for detecting surface defects in a graphite crucible includes a base and a rotating mechanism and a lifting mechanism mounted on the top of the base. The rotating mechanism includes a turntable rotatably connected to the base, and a mounting base made of transparent material is connected to the top of the turntable. A first detection seat is provided between the turntable and the mounting base. The lifting mechanism includes a support base, an adjusting screw mounted on the support base, a slider threadedly connected to the adjusting screw, and a first hydraulic rod mounted on the slider. A fixed plate is connected to the driving end of the first hydraulic rod, and a second, third, and fourth detection seat are provided at the bottom of the fixed plate.

[0006] Furthermore, the rotating mechanism also includes a motor mounted on the base, the output end of the motor being connected to the turntable, and the turntable being connected to the mounting base via a support rod.

[0007] Furthermore, a light is provided on the top of the turntable.

[0008] Furthermore, the mounting base has a mounting groove, and the mounting groove has clamping plates symmetrical about the central axis of the mounting groove. The opposing sides of the two clamping plates are fixedly connected to screws, and the opposing ends of the two screws pass through the groove wall of the mounting groove and are connected to a rotating wheel.

[0009] Furthermore, the clamping plate is a transparent plate.

[0010] Furthermore, the support base is also provided with a drive component for driving the adjusting screw to rotate.

[0011] Furthermore, the bottom of the fixing plate is provided with an L-shaped plate, the bottom of the L-shaped plate is provided with a first telescopic rod, the bottom of the first telescopic rod is provided with a second detection seat, the inner wall of the L-shaped plate is provided with a second hydraulic rod, the driving end of the second hydraulic rod is connected to the second telescopic rod, and the bottom of the second telescopic rod is provided with the third detection seat and the fourth detection seat.

[0012] Furthermore, the first and fourth detection seats are parallel to each other, the second and third detection seats are parallel to each other, and the first and second detection seats are perpendicular to each other.

[0013] The technical solution of this utility model has at least the following advantages and beneficial effects: The rotating mechanism drives the turntable and mounting base to rotate, thereby rotating the crucible placed on the mounting base. During the crucible's rotation, the outer wall, inner wall, and bottom of the crucible are inspected, enabling comprehensive inspection at a single station and meeting the requirements for continuous and efficient inspection. The mounting base is transparent, and the first inspection seat located between the turntable and the mounting base can inspect the outer bottom surface of the crucible. The supporting base and adjusting screw can adjust the height of the slider, thereby adjusting the height of the second, third, and fourth inspection seats. Simultaneously, the first hydraulic rod can adjust the horizontal distance between the fixing plate and the crucible, thereby adjusting the position of the second, third, and fourth inspection seats. This allows the second inspection seat to inspect the outer wall of the crucible, the third inspection seat to inspect the inner wall of the crucible, and the fourth inspection seat to inspect the inner bottom surface of the crucible, completing multi-directional inspection of the crucible during its rotation.

[0021] Example 1 Reference Figures 1-4 This embodiment provides an auxiliary device for detecting surface defects in graphite crucibles, including a base 1 and a rotating mechanism and a lifting mechanism mounted on the top of the base 1. The rotating mechanism includes a turntable 2 rotatably connected to the base 1, and a mounting base 3 connected to the top of the turntable 2. The mounting base 3 is made of transparent material, and a first detection seat 16 is provided between the turntable 2 and the mounting base 3. The lifting mechanism includes a support base 4, an adjusting screw 5 mounted on the support base 4, a slider 6 threadedly connected to the adjusting screw 5, and a first hydraulic rod 7 mounted on the slider 6. The driving end of the first hydraulic rod 7 is connected to a fixing plate 8, and a second detection seat 12, a third detection seat 14, and a fourth detection seat 15 are provided at the bottom of the fixing plate 8.

[0022] The rotating mechanism drives the turntable 2 and the mounting base 3 to rotate, thereby causing the crucible placed on the mounting base 3 to rotate. During the rotation of the crucible, the outer wall, inner wall, and bottom of the crucible are inspected, enabling comprehensive inspection at the same station and meeting the requirements for continuous and efficient inspection. The mounting base 3 is transparent, and the first inspection seat 16 located between the turntable 2 and the mounting base 3 can inspect the outer bottom surface of the crucible. The first inspection seat 16 is located at the center of the turntable 2, and the central axes of the turntable 2 and the crucible coincide.

[0023] The support base 4 and adjusting screw 5 can adjust the height of the slider 6, thereby adjusting the height of the second detection base 12, the third detection base 14, and the fourth detection base 15. Simultaneously, the first hydraulic rod 7 can adjust the horizontal distance between the fixing plate 8 and the crucible, thus adjusting the positions of the second detection base 12, the third detection base 14, and the fourth detection base 15. This allows the second detection base 12 to inspect the outer wall of the crucible, the third detection base 14 to inspect the inner wall of the crucible, and the fourth detection base 15 to inspect the inner bottom surface of the crucible, completing multi-directional inspection of the crucible during its rotation. Each of the first detection base 16, the second detection base 12, the third detection base 14, and the fourth detection base 15 is equipped with a camera, which can acquire images of the outer wall, inner wall, and bottom of the crucible. Image analysis is then used to determine the surface defect detection results of the crucible.

[0024] In a preferred embodiment, the rotating mechanism further includes a motor 17 mounted on the base 1, the output end of the motor 17 being connected to the turntable 2, and the turntable 2 being connected to the mounting base 3 via a support rod 18.

[0025] In a preferred embodiment, the turntable 2 is equipped with a lighting lamp 19 on its top. Since the mounting base 3 and the crucible will block the light source, the lighting lamp 19 makes it easier for the first detection base 16 to more clearly detect the outer bottom surface of the crucible.

[0026] In a preferred embodiment, the mounting base 3 has a mounting groove, and the mounting groove contains clamping plates 20 symmetrical about the central axis of the mounting groove. Screws 21 are fixedly connected to opposite sides of the two clamping plates 20, and opposite ends of the two screws 21 pass through the groove wall and are connected to rotating wheels 22. The crucible is placed in the mounting groove, and the rotating wheels 22, screws 21, and clamping plates 20 clamp and fix the crucible, preventing it from shaking during rotation and improving the safety of crucible testing. To prevent missed detections, after the rotating mechanism rotates the crucible one revolution, the crucible is manually adjusted to change its clamping position, and the test is performed again, avoiding the impact of the clamping plates 20 on the integrity of the crucible testing.

[0027] In a preferred embodiment, the clamping plate 20 is a transparent plate.

[0028] In a preferred embodiment, the support base 4 is further provided with a driving component for driving the adjusting screw 5 to rotate. The driving component is a servo motor. The servo motor drives the adjusting screw 5 to rotate, and the forward and reverse rotation of the adjusting screw 5 drives the slider 6 to rise or fall, causing the fixed plate 8 to rise or fall. This allows for adjustment of the height of the second detection seat 12, the third detection seat 14, and the fourth detection seat 15, facilitating the entry and exit of the detection seats on the inner wall of the crucible from the crucible.

[0029] In a preferred embodiment, the bottom of the fixing plate 8 is provided with an L-shaped plate 9, the bottom of the L-shaped plate 9 is provided with a first telescopic rod 10, the bottom of the first telescopic rod 10 is equipped with a second detection seat 12, the inner wall of the L-shaped plate 9 is provided with a second hydraulic rod 11, the driving end of the second hydraulic rod 11 is connected to a second telescopic rod 13, and the bottom of the second telescopic rod 13 is equipped with a third detection seat 14 and a fourth detection seat 15. The first telescopic rod 10 and the second telescopic rod 13 can be commercially available electric telescopic rods. The first telescopic rod 10 can adjust the vertical position of the second detection seat 12 outside the crucible, and the second telescopic rod 13 can adjust the vertical position of the third detection seat 14 and the fourth detection seat 15 inside the crucible, selecting the most suitable vertical position for detection and improving detection accuracy. The second hydraulic rod 11 can adjust the horizontal position of the second telescopic rod 13 to facilitate adjustment of the lateral position of the third detection seat 14 and the fourth detection seat 15 inside the crucible, making accurate detection easier.

[0030] In a preferred embodiment, the first detection seat 16 and the fourth detection seat 15 are parallel to each other, the second detection seat 12 and the third detection seat 14 are parallel to each other, and the first detection seat 16 and the second detection seat 12 are perpendicular to each other.

[0031] Working principle: The crucible is placed in the mounting slot of the mounting base 3. The rotating wheel 22 drives the screw 21 to rotate, causing the two clamping plates 20 to move closer to the crucible, thus clamping and fixing the crucible. The driving component drives the adjusting screw 5 to rotate, causing the slider 6 and the fixing plate 8 to rise or fall synchronously. At the same time, the first hydraulic rod 7 is used to adjust the position of the first telescopic rod 10 and the second telescopic rod 13, so that the first telescopic rod 10 is located outside the crucible and the second telescopic rod 13 is located inside the crucible. Then, the adjusting screw 5, the first telescopic rod 10 and the second telescopic rod 13 are used to adjust the vertical position of the second detection seat 12, the third detection seat 14 and the fourth detection seat 15. The second hydraulic rod 11 is used to adjust the lateral position of the third detection seat 14 and the fourth detection seat 15, all adjusted to the appropriate detection position. Motor 17 drives turntable 2 to rotate, synchronously rotating the crucible on mounting base 3. During the crucible's rotation, the first detection seat 16, the second detection seat 12, the third detection seat 14, and the fourth detection seat 15 respectively inspect the outer bottom surface, outer wall, inner wall, and inner bottom surface of the crucible. Furthermore, for improved accuracy, the fourth detection seat 15 can be adjusted to the center of the crucible's interior using the second hydraulic rod 11.

[0032] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
