Specific embodiments

[0018] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model.

[0019] Obviously, many specific details are set forth in the following description in order to fully understand the present utility model. However, the present utility model can also be implemented in other ways different from those described herein. Therefore, the present utility model is not limited by the limitations of the specific embodiments disclosed in the following specification.

[0020] Please refer to Figures 1-4, the present utility model provides a weld tightness detection tooling, including a workbench 1. A groove is formed at the top of the workbench 1. A second bidirectional threaded rod 21 is rotatably connected inside the groove. At both ends of the second bidirectional threaded rod 21 inside the groove, second threaded sleeve blocks 31 are threadedly sleeved. One end of the second bidirectional threaded rod 21 penetrates outside the workbench 1, and a runner 20 is fixedly connected to the end of the second bidirectional threaded rod 21 outside the workbench 1. At the top of both second threaded sleeve blocks 31, equipment boxes 7 are fixedly connected. At the top of both equipment boxes 7, chutes are formed. On one side of one equipment box 7, a second servo motor 8 is fixedly connected. The output shaft of the second servo motor 8 is fixedly connected with a first bidirectional threaded rod 9. Symmetrically two first threaded sleeve blocks 16 are threadedly sleeved inside the groove at the top of one equipment box 7 by the first bidirectional threaded rod 9. A plug post 10 is fixedly connected inside the groove at the top of the other equipment box 7. The plug post 10 is slidably sleeved with symmetrically two other first threaded sleeve blocks 16 inside the groove of the equipment box 7. At the top of all four first threaded sleeve blocks 16, support blocks 17 are fixedly connected. At the top of all four support blocks 17, arc-shaped blocks 18 are fixedly connected. Arc-shaped openings are formed on the outer surfaces of all four arc-shaped blocks 18. Inside the arc-shaped openings at the top of one equipment box 7, two rotating clamping wheels 19 are rotatably connected. On one side of the arc-shaped blocks 18 at the top of the other equipment box 7, a component box 11 is fixedly connected to each. Inside one side of the inner cavities of both component boxes 11, a third rotating shaft 26 is rotatably connected. One end of both third rotating shafts 26 is rotatably inserted into the other two arc-shaped openings. The other two rotating clamping wheels 19 are respectively rotatably connected to the outer surfaces of one end of both third rotating shafts 26 inside the two arc-shaped openings. On one side of both support blocks 17 on one side of one equipment box 7, sleeves 22 are fixedly connected. On one side of the other two support blocks 17 on one side of the other equipment box 7, plug shafts 23 are fixedly connected. The two plug shafts 23 are slidably inserted into the two sleeves 22. A synchronous rotation mechanism is arranged inside both component boxes 11, and both third rotating shafts 26 are fixedly sleeved on the synchronous rotation mechanism. A cleaning mechanism is arranged on one side of the workbench 1. By rotating the runner 20 and using the rotation of the second bidirectional threaded rod 21, the two second threaded sleeve blocks 31 can be driven to move towards or away from each other inside the chute, thereby adjusting the distance between the two equipment boxes 7, and thus adjusting the distance between the four rotating clamping wheels 19. By using this method of adjusting the distance between the four rotating clamping wheels 19, the clamping and supporting positions of the pipe fittings are adjusted to clamp pipe fittings of different lengths. By starting the second servo motor 8, the two first threaded sleeve blocks 16 are driven to move towards or away from each other inside the groove of one equipment box 7 by the rotation of the rotating clamping wheels 19. Through the sliding insertion of the two sleeves 22 and the plug shafts 23, the distance between the four rotating clamping wheels 19 is adjusted. By using this distance adjustment,The four rotating clamping wheels 19 clamp welded pipe fittings with different pipe diameters. Through the synchronous rotation mechanism, the rotation of two third rotating shafts 26 drives the two rotating clamping wheels 19 to rotate in the same direction, thereby driving the clamped rotation to rotate, so as to cooperate with the cleaning part to clean the internal welds of the pipe fittings. After the cleaning is completed, the rotation of the pipe fittings also facilitates the spraying of magnetic powder.

[0021] It should be noted that the synchronous rotation mechanism mentioned in the above description includes a third servo motor 12. When the third servo motor 12 is turned on, the fourth rotating shaft 29 inside a component box 11 rotates and drives a first bevel gear 27 to rotate, thereby causing a second bevel gear 28 to rotate. By using the insertion of the second rotating shaft 13 and the cross plug 14, the rotation of the second threaded sleeve block 31 drives another second bevel gear 28 to rotate. At this time, through the fifth rotating shaft 30 and the sixth rotating shaft 32, the two first bevel gears 27 and the two second bevel gears 28 all rotate synchronously. At this time, through the sleeving of four synchronous wheels 24 and two synchronous belts 25 respectively, the two third rotating shafts 26 rotate in the same direction, so that the two rotating clamping wheels 19 can rotate in the same direction, thereby driving the clamped pipe fittings to rotate. By using the insertion of the second rotating shaft 13 and the cross plug 14, when the distance between the two rotating clamping wheels 19 is adjusted, the two rotating clamping wheels 19 can still rotate synchronously.

[0022] Furthermore, the cleaning mechanism mentioned in the above description includes an electric cylinder 2. Through the telescoping of the electric cylinder 2 and the turning on of the first servo motor 4 on the connecting plate 3, the first rotating shaft 5 can be used to drive the cleaning soft block 6 to rotate for cleaning, and the cleaning position of the cleaning soft block 6 can be adjusted, so as to facilitate the cleaning of the pipe fitting welds.

[0023] To facilitate the stable sliding of the two second threaded sleeve blocks 31 and the two first threaded sleeve blocks 16, both sides of the two second threaded sleeve blocks 31 are in contact with both sides of the chute, and both sides of the two first threaded sleeve blocks 16 are in contact with both sides of the groove.

[0024] In order to prevent the arrangement of the two component boxes 11 from hindering the rotation of the two rotating clamping wheels 19 driving the clamped pipe fittings, the diameter of the rotating clamping wheels 19 is larger than the diameter of the component boxes 11, and the second rotating shaft 13 and the cross plug 14 are both located below the rotating clamping wheels 19.

[0025] The preferred embodiments of the present invention have been described in detail above in conjunction with the accompanying drawings. However, the present invention is not limited to the specific details in the above embodiments. Within the scope of the technical concept of the present invention, various simple modifications can be made to the technical solution of the present invention, and these simple modifications all fall within the protection scope of the present invention.

[0026] In addition, it should be noted that, for the various specific technical features described in the above specific embodiments, they can be combined in any appropriate manner without contradiction. To avoid unnecessary repetition, the present utility model will not separately describe various possible combination methods.

[0027] In addition, any combination can be made among the various different embodiments of the present utility model, as long as it does not violate the idea of the present utility model, and it should equally be regarded as the content disclosed by the present utility model.
