Description

Technical Field

[0001] This utility model relates to the field of flaw detector technology, specifically to a high-efficiency flaw detector rotary drive device. Background Technology

[0002] Flaw detectors are generally non-destructive testing equipment. They are specifically designed for industries such as shipbuilding, petroleum, chemical, machinery, aerospace, transportation, and construction to inspect the quality of materials, parts, and welding of ship hulls, pipelines, high-pressure vessels, boilers, aircraft, vehicles, and bridges, as well as the quality of various light metal, rubber, and ceramic processed parts.

[0003] A search revealed an existing patent (publication number: CN 221707360 U) disclosing a rotary drive device for an oil casing magnetic flux leakage flaw detector. The device includes a base, a first support plate, a flipping roller, a drive roller, and a second support plate. A first servo motor is mounted at one end of the base, and a second threaded rod extending into the base is mounted at the output end of the first servo motor. A second threaded tube is threaded onto the outer side of the second threaded rod, and a second support plate is mounted on the top of the second threaded tube. A third servo motor is mounted on one side of the top of the second support plate. This invention incorporates a second rotating shaft, a drive roller, a conveying rubber strip, and a third servo motor. In use, the third servo motor drives the drive roller to rotate at a constant speed via the second rotating shaft. This causes the conveying rubber strip, wound in a spiral shape on the outer side of the drive roller, to propel the oil casing to the position of the magnetic flux leakage flaw detector for flaw detection.

[0004] However, although the above solution can achieve the purpose of rotating the sleeve, the fixed sleeve part is not adjustable. When a large sleeve is placed on the equipment, it may fall off the equipment.

[0005] In view of this, this utility model proposes a high-efficiency rotary drive device for a flaw detector. Utility Model Content

[0006] This utility model proposes a high-efficiency rotary drive device for a flaw detector, which solves the problem that although related technologies can achieve the purpose of rotating the casing, the fixed casing part is not adjustable, which may cause the casing to fall off the equipment when a large casing is placed on the equipment.

[0007] The technical solution of this utility model is as follows: A high-efficiency flaw detector rotary drive device includes a base, a first servo motor fixedly connected to the top of the base, a positive and negative lead screw fixedly connected to the output end of the first servo motor and rotatably connected to the base, two sets of sliders slidably connected to the base connected to the surface of the positive and negative lead screws, mounting screws rotatably connected inside the two sets of sliders, two sets of control rings threadedly connected to the surface of the two sets of mounting screws, a connecting shaft fixedly connected to one side of the control ring, a motion ring slidably connected to the mounting screw rotatably connected to the surface of the connecting shaft, a control plate rotatably connected to the top of the motion ring, an adjusting ring rotatably connected to the surface of the control plate, an anti-slip pad fixedly connected to the surface of the left adjusting ring, a telescopic column fixedly connected to the mounting screw fixedly connected to the inner wall of the adjusting ring, and a second servo motor fixedly connected to the output end of the left slider and fixedly connected to the mounting screw.

[0008] Preferably, each of the two sets of sliders has a mounting plate fixedly connected to its top, and each of the two sets of mounting plates has a transmission screw threadedly connected inside. The tail of the transmission screw is rotatably connected to a baffle, and one end of the baffle is fixedly connected to a slide rod that is slidably connected to the mounting plate.

[0009] Preferably, both sets of sliders are U-shaped, and the two sets of sliders form a reverse sliding structure through positive and negative lead screws.

[0010] Preferably, the connecting shaft has a "T" shaped structure, and the connecting shaft forms a rotating structure inside the motion ring through a control ring.

[0011] Preferably, the control plate is set to an inclined state, and the motion ring slides horizontally along the mounting screw via the connecting shaft.

[0012] Preferably, the anti-slip pad completely covers the surface of the three sets of adjustment rings on the left side, and the two sets of mounting screws are arranged parallel to each other.

[0013] Preferably, the two sets of baffles are arranged on the same horizontal plane, and the two sets of baffles cover the two ends of the two sets of adjusting rings.

[0014] Preferably, the slide bar is in close contact with the mounting plate, and the baffle forms a movable structure through a transmission screw.

[0015] The working principle and beneficial effects of this utility model are as follows:

[0016] In this invention, a control ring is provided. Since different sleeves have different sizes, if the size of the adjusting ring is too small, the sleeve may fall off when the sleeve rotates. At this time, the control ring can be rotated to move towards the center of the mounting screw. The connecting shaft will also rotate inside the moving ring and apply a thrust to the moving ring. When the moving ring slides, it will cause the control plate to rotate around itself and push the adjusting ring during rotation. At this time, under the limit of the telescopic column, the adjusting ring will move horizontally away from the mounting screw, thus achieving the purpose of size adjustment.

[0017] In this invention, a baffle is provided to limit the movement of the sleeve during rotation, preventing the sleeve from shifting. When it is necessary to adjust the baffle to fit the sleeve, the transmission screw can be rotated, and the baffle can be moved horizontally to the position where it fits the sleeve under the limiting of the sliding rod, thus achieving the purpose of limiting its movement.

[0025] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model. Example

[0026] A preferred embodiment of the high-efficiency flaw detector rotary drive device provided by this utility model is, for example... Figures 1 to 5 As shown: A high-efficiency flaw detector rotary drive device includes a base 1. A first servo motor 2 is fixedly connected to the top of the base 1. A positive and negative lead screw 3, which is rotatably connected to the base 1, is fixedly connected to the output end of the first servo motor 2. Two sets of sliders 4, which are slidably connected to the base 1, are threadedly connected to the surface of the positive and negative lead screw 3. Mounting screws 5 are rotatably connected to the inside of each set of sliders 4. Two sets of control rings 6 are threadedly connected to the surface of each set of mounting screws 5. A connecting shaft 7 is fixedly connected to one side of the control ring 6. A motion ring 8, which is slidably connected to the mounting screw 5, is rotatably connected to the surface of the connecting shaft 7. A control plate 9 is rotatably connected to the top of the motion ring 8. An adjusting ring 10 is rotatably connected to the surface of the control plate 9. An anti-slip pad 11 is fixedly connected to the surface of the left adjusting ring 10. A telescopic column 12, which is fixedly connected to the mounting screw 5, is fixedly connected to the inner wall of the adjusting ring 10. A second servo motor 16, whose output end is fixedly connected to the mounting screw 5, is fixedly connected to the surface of the left slider 4.

[0027] In this embodiment, both sets of sliders 4 are U-shaped and form a reverse sliding structure through positive and negative lead screws 3. By setting positive and negative lead screws 3, the two sets of sliders 4 can be controlled to slide in opposite directions during rotation, thereby adjusting the position of the two sets of adjusting rings 10.

[0028] In this embodiment, the connecting shaft 7 has a "T" shaped structure. The connecting shaft 7 forms a rotating structure inside the motion ring 8 through the control ring 6. Rotating the control ring 6 causes it to move toward the center of the mounting screw 5. At this time, the connecting shaft 7 will also rotate inside the motion ring 8 and apply a thrust to the motion ring 8.

[0029] In this embodiment, the control plate 9 is set to an inclined state, and the motion ring 8 slides horizontally along the mounting screw 5 via the connecting shaft 7. When the motion ring 8 slides, it will cause the control plate 9 to rotate around itself, and push the adjusting ring 10 when rotating. At this time, under the limit of the telescopic column 12, the adjusting ring 10 will move horizontally away from the mounting screw 5, thereby achieving the purpose of adjusting the size.

[0030] In this embodiment, the anti-slip pad 11 completely covers the surface of the three sets of adjustment rings 10 on the left side, and the two sets of mounting screws 5 are arranged in parallel to each other. Under the action of the anti-slip pad 11, the frictional resistance will increase. When the left adjustment ring 10 rotates, it will drive the sleeve to rotate with the assistance of the right adjustment ring 10, thereby facilitating the flaw detection at different positions of the sleeve. Example

[0031] Based on Embodiment 1, a preferred embodiment of the high-efficiency flaw detector rotary drive device provided by this utility model is as follows: Figures 1 to 5As shown: The top of both sets of sliders 4 are fixedly connected to mounting plates 17. The interior of both sets of mounting plates 17 is threaded with transmission screws 13. The tail of the transmission screws 13 is rotatably connected to baffles 15. One end of the baffles 15 is fixedly connected to a slide rod 14 that is slidably connected to the mounting plates 17.

[0032] In this embodiment, two sets of baffles 15 are set on the same horizontal plane. The two sets of baffles 15 block the two ends of the two sets of adjusting rings 10. By setting the baffles 15, the baffles 15 can limit the sleeve when it rotates, so as to prevent the sleeve from moving when it rotates.

[0033] In this embodiment, the slide rod 14 is tightly fitted with the mounting plate 17, and the baffle 15 forms a movable structure through the transmission screw 13. When it is necessary to adjust the baffle 15 to fit the sleeve, the transmission screw 13 can be rotated. Under the limitation of the slide rod 14, the baffle 15 can move horizontally to the position where it fits the sleeve, thus achieving the purpose of limiting its position.

[0034] The working principle and usage process of this utility model are as follows: First, place the sleeve to be tested between the two sets of adjusting rings 10. Then, turn on the second servo motor 16 to control the left mounting screw 5 to rotate. The anti-slip pad 11 increases frictional resistance. When the left adjusting ring 10 rotates, it will drive the sleeve to rotate with the assistance of the right adjusting ring 10, thus facilitating flaw detection at different positions on the sleeve. Since different sleeves have different sizes, if the size of the adjusting ring 10 is too small, the sleeve may fall off when it rotates. In this case, the control ring 6 can be rotated to move it towards the center of the mounting screw 5. The connecting shaft 7 also rotates inside the moving ring 8 and applies a thrust to the moving ring 8. When the moving ring 8 slides, the control plate 9 will rotate around itself and push the adjusting ring 10 during rotation. At this time, under the limit of the telescopic column 12, the adjusting ring 10 will move horizontally away from the mounting screw 5, thereby achieving the purpose of adjusting the size. By setting the baffle 15, the baffle 15 can limit the sleeve when it rotates, preventing the sleeve from moving during rotation. When it is necessary to adjust the baffle 15 to fit the sleeve, the transmission screw 13 can be rotated. Under the limit of the slide rod 14, the baffle 15 can move horizontally to the position where it fits the sleeve, thereby achieving the purpose of limiting it.

[0035] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
