Abstract
Description
Technical Field
[0001] This utility model relates to the field of oil pipe joint technology, and more specifically, to a multi-station switching device for precision testing of oil pipe joints. Background Technology
[0002] An oil pipe joint is made up of at least two parts welded together. Oil pipes are widely used in production and daily life, and oil pipe joints are essential components for connecting oil pipes. The quality of oil pipe joints is directly related to the quality of oil pipes, and visual inspection of the surface of oil pipe joints is an essential step.
[0003] In practical use, before testing multiple tubing joints, the tubing joints in batches need to be repeatedly positioned. The positioning process usually involves using bolts to press and position the surface of the tubing joints. This step takes a certain amount of time, which reduces the continuity of tubing joint testing and reduces the testing efficiency of batch tubing joints. Utility Model Content

[0005] To achieve the above objectives, this utility model provides the following technical solution:
[0006] A multi-station switching device for precision testing of oil pipe joints includes an operating table. A visual inspection camera is installed on one side of the operating table. A base frame is fixedly connected to the upper surface of the operating table, and a turntable is rotatably connected to the inner side of the base frame. Multiple positioning mechanisms are installed on the top of the turntable. Each positioning mechanism includes a positioning frame, the lower surface of which is fixedly connected to the upper surface of the turntable. A limit plate is rotatably connected to the inner side of the positioning frame. A gear is coaxially connected to the top of the limit plate. The outer side of the gear is rotatably connected to the inner side of the positioning frame. Two sliding contacts are slidably connected to the inner side of the positioning frame. The frame includes a sliding frame with a rack fixedly connected to one side, the rack meshing with a gear.

Telescopic rods are fixedly connected to both ends of the positioning frame, with the ends of the telescopic rods fixedly connected to one side of the sliding frame. A spring is sleeved on the outer side of the telescopic rod. An adjustment mechanism is provided inside the base frame and the turntable.
[0007] By adopting the above technical solution: utilizing the driven counter-movement of two sliding frames, combined with the pushing of the two sliding frames by the telescopic rod and spring one, the two positioning blocks one and positioning block two, along with the multiple grooves on their surfaces, achieve multi-point support and positioning of the oil pipe joint surface, simplifying the positioning steps of the oil pipe joint and improving the continuity of oil pipe joint inspection.
[0008] As a further description of the above technical solution: the switching mechanism includes multiple springs II, one end of each spring II is fixedly connected to the inner side of the base frame, and the other end of each spring II is fixedly connected to a push block. The outer side of the push block is slidably connected to the inner side of the base frame. One end of the push block is rotatably connected to a rotating roller. An annular guide groove is provided on the inner side of the base frame. A limit tube is fixedly connected to the inner side of the base frame. A rotating shaft is rotatably connected to the inner side of the limit tube. The top end of the rotating shaft is fixedly connected to the lower surface of the turntable. A bottom ring is fixedly connected to the bottom of the turntable. A positioning groove is provided on the outer side of the bottom ring.

[0009] By adopting the above technical solution, the rotation angle of the turntable and bottom ring is positioned by using spring 2, push block and rotating roller, so that multiple oil pipe joints can be accurately moved to the direct below the visual inspection camera, thus achieving accurate visual inspection.
[0010] The technical effects and advantages of this utility model are as follows:
[0011] 1. By setting up a positioning mechanism, compared with the existing technology, the two opposing and driven positioning blocks 1 and 2 are combined with the multiple grooves on their surfaces to achieve multi-point support and positioning of the oil pipe joint surface, thereby achieving stable positioning of multiple oil pipe joints, simplifying the repeated loading and unloading operation steps of multiple oil pipe joints, and improving the efficiency of precision testing of multiple oil pipe joints.

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.
[0024] The embodiments disclosed in this application are as follows: Figures 1-9The precision inspection multi-station switching device for oil pipe joints shown includes an operating table 1. A visual inspection camera 2 is installed on one side of the operating table 1. A base frame 3 is fixedly connected to the upper surface of the operating table 1. A turntable 4 is rotatably connected to the inner side of the base frame 3. Multiple positioning mechanisms are installed on the top of the turntable 4. The positioning mechanism includes a positioning frame 5. The lower surface of the positioning frame 5 is fixedly connected to the upper surface of the turntable 4. A limit plate 6 is rotatably connected to the inner side of the positioning frame 5. A gear 7 is coaxially connected to the top of the limit plate 6. The outer side of the gear 7 is rotatably connected to the inner side of the positioning frame 5. Two sliding frames 8 are slidably connected to the inner side of the positioning frame 5. A rack 9 is fixedly connected to one side of the sliding frame 8. One side of the rack 9 meshes with the gear 7. Three support rods 10 are fixedly connected to one side of the sliding frame 8. Positioning blocks 11 are fixedly connected to the ends of the three support rods 10. Positioning blocks are fixedly connected to the upper surface of the positioning frame 5. The surfaces of positioning blocks 11 and 12 are provided with multiple grooves 13 for fitting the oil pipe joint. Both ends of the positioning frame 5 are fixedly connected to telescopic rods 14. The ends of the telescopic rods 14 are fixedly connected to one side of the sliding frame 8. A spring 15 is sleeved on the outside of the telescopic rods 14. The base frame 3 and the turntable 4 are provided with an adjustment mechanism. By using gear 7 to mesh with the racks 9 on both sides, the sliding frame 8 on one side can be pulled while the sliding frame 8 on the other side can move in the opposite direction. Combined with the elastic push of the telescopic rods 14 and the spring 15, the positioning blocks 11 on both sides and the positioning block 12 at the bottom can provide multi-point support and clamping for the surface of the oil pipe joint. The multiple grooves 13 on the surfaces of positioning blocks 11 and 12 can further fit with the surface of the oil pipe joint, simplifying the positioning steps of the oil pipe joint.
[0025] Reference Figure 2 , Figure 3 , Figure 5As shown, the switching mechanism includes multiple springs 16. One end of each spring 16 is fixedly connected to the inner side of the base frame 3, and the other end of each spring 16 is fixedly connected to a push block 17. The outer side of the push block 17 is slidably connected to the inner side of the base frame 3. One end of the push block 17 is rotatably connected to a rotating roller 18. An annular guide groove is provided on the inner side of the base frame 3. A limit tube 19 is fixedly connected to the inner side of the base frame 3. A rotating shaft 20 is rotatably connected to the inner side of the limit tube 19. The top end of the rotating shaft 20 is fixedly connected to the lower surface of the turntable 4. A bottom ring 21 is fixedly connected to the bottom of the turntable 4. A positioning groove is provided on the outer side of the bottom ring 21, and multiple toothed grooves 2 are provided on the inner side of the bottom ring 21. 2. A servo motor 23 is fixedly connected to the inner side of the operating table 1. A gear 24 is fixedly connected to the output end of the servo motor 23. The outer side of the gear 24 meshes with multiple tooth grooves 22. The meshing transmission of the gear grooves 22 on the inner side of the bottom ring 21 by the servo motor 23 and the gear 24 causes the bottom ring 21 to drive the turntable 4 to rotate on the top of the base frame 3. Multiple springs 16 push the push block 17 and the rotating roller 18 to limit the outer groove of the bottom ring 21, so that the turntable 4 can drive multiple oil pipe joints to perform directional deflection, ensuring that the oil pipe joints can be accurately detected by the visual inspection camera 2 after switching between multiple work positions.
[0026] The working principle of this utility model is as follows: When performing precision testing on the oil pipe joint, the operator first positions the oil pipe joint on the positioning frame 5 closest to themselves. Then, the sliding frame 8 on one side of the positioning frame 5 is pulled outwards, causing the sliding frame 8 to drive the rack 9 to mesh with the gear 7. The rotation of the gear 7 is supported by the limiting plate 6, ensuring smooth transmission. Then, the gear 7 meshes with the rack 9 on the other side, causing the rack 9 to drive the opposite sliding frame 8 to move in opposite directions, thereby separating the two positioning blocks 11. After leaving, place the bottom end of the oil pipe joint into the corresponding groove 13 on the surface of the positioning block 2 12, and then release the pull on the sliding frame 8. Then, the two springs 15 at both ends of the positioning frame 5 push the corresponding sliding frame 8 in conjunction with the extension and retraction of the telescopic rod 14, so that the two sliding frames 8 slide in opposite directions. In this way, the two sliding frames 8 drive the positioning block 11 through the support rod 10 to clamp the two sides of the oil pipe joint, and the multiple grooves 13 on the opposite surface of the two positioning blocks 11 fit with the two sides of the oil pipe joint to achieve multi-point support and positioning of the oil pipe joint.
[0027] Then, servo motor 23 is restarted to drive gear 24 to mesh with the toothed groove 22 on the inner side of bottom ring 21. This causes bottom ring 21 to rotate under the guidance of the annular guide groove on the inner side of base frame 3, while shaft 20 rotates inside the limit tube 19. This causes turntable 4 to continuously rotate on top of base frame 3, driving multiple positioning frames 5 to rotate. Figure 5 and Figure 8The push block 17 and the rotating roller 18, driven by multiple springs 16 on the inner side of the base frame 3, deflect multiple slots on the outer side of the bottom ring 21 at the same angle, so that the deflected oil pipe joint is always within the detection range of the visual inspection camera 2. Then, as the multiple positioning frames 5 rotate, the operator repeats the above operation to position the multiple oil pipe joints sequentially above the multiple positioning frames 5. Finally, when the positioning frame 5 with the fixed oil pipe joint rotates to the bottom of the visual inspection camera 2, the surface of the oil pipe joint is visually observed through the visual inspection camera 2. After the multiple oil pipe joints are inspected in sequence, the continuous operation of loading and unloading multiple oil pipe joints can be realized.
