A circular slot is formed inside the limiting rod, at which point the circular plate is located inside the circular slot. A moving rod is connected to the other end of the first fixed column via the rotating assembly. The rotating assembly allows the moving rod and the limiting rod to rotate. When the flange forging is fixed on the moving rod and the limiting rod, the moving rod and the limiting rod allow the flange forging to rotate, making it more convenient to flip the flange forging during quality inspection. 3. This quality inspection clamping device for flange forgings comprises a storage box installed on the top of a base plate, with partitions welded inside the storage box and internally threaded holes on the sides of the partitions. The partitions are evenly distributed, and a second externally threaded rod is fitted inside the internally threaded hole. A turntable is welded to one end of the second externally threaded rod, which then penetrates the storage box. When a defective flange forging is detected during the use of the quality inspection clamping device, the flange forging can be placed inside the storage box. Then, the second externally threaded rod is used to penetrate the flange forging and embed it into the internally threaded hole, thus limiting the flange forging to the side of the partition in the storage box. When another defective flange forging is detected, it can be placed into the storage box in sequence, and the second externally threaded rod is rotated again until it is embedded into the internally threaded hole. This device provides a convenient location for storing flange forgings. Attached Figure Description

[0023] To better understand the purpose, structure, and function of this invention, the following detailed description of a quality inspection clamping device for flange forgings is provided in conjunction with the accompanying drawings.

[0024] like Figure 1-6 As shown, a quality inspection clamping device for flange forgings according to the present invention includes a base plate 1, a support plate 2 welded to the top of the base plate 1, a sliding groove 3 formed on the side of the support plate 2, a slider 4 being engaged inside the sliding groove 3, a first fixing post 5 mounted on the side of the slider 4, a moving rod 7 mounted on the other end of the first fixing post 5, a second fixing post 6 welded to the side of the support plate 2, and a limiting rod 8 mounted on the other end of the second fixing post 6. By installing the limiting rod 8 and the moving rod 7, the limiting rod 8 can limit the flange forging, and then the moving rod 7 can move the position to expand the interior of the flange forging, so that the flange forging can be fixed, which is very convenient to use. An internal thread seat 13 is welded to the top of the slider 4, a lead screw 14 is sleeved inside the internal thread seat 13, a bearing 15 is welded to the surface of the lead screw 14, and the base plate 1 is welded to the surface of the bearing 15. By installing the bearing 15, the bearing 15 can provide the lead screw 14 with the effect of in-situ rotation. At this time, under the action of the internal thread seat 13, the slider can move inside the sliding groove 3, which is very convenient to use.

[0025] The other end of the second fixed column 6 is connected to the limiting rod 8 via a rotating assembly. The rotating assembly includes a fixed rod 9, a circular plate 10, a groove 11, and a circular slot 12. The fixed rod 9 is welded to the other end of the second fixed column 6, and the circular plate 10 is welded to the other end of the fixed rod 9. The groove 11 is opened inside the limiting rod 8, and the fixed rod 9 is located inside the groove 11. The circular slot 12 is opened inside the limiting rod 8, and the circular plate 10 is located inside the circular slot 12. The other end of the first fixed column 5 is connected to the moving rod 7 via a rotating assembly. By installing the rotating assembly, the moving rod 7 and the limiting rod 8 can be rotated. When the flange forging is fixed on the moving rod 7 and the limiting rod 8, the flange forging can be rotated using the moving rod 7 and the limiting rod 8. This makes it more convenient to flip the flange forging during quality inspection.

[0026] A storage box 18 is installed on the top of the base plate 1. A partition 22 is welded inside the storage box 18. Internal threaded holes 23 are opened on the side of the partition 22. The partitions 22 are evenly distributed. A second external threaded rod 24 is sleeved inside the internal threaded holes 23. A turntable 25 is welded to one end of the second external threaded rod 24. The second external threaded rod 24 passes through the storage box 18. By installing the storage box 18, when unqualified flange forgings are detected during the use of the quality inspection clamping device for flange forgings, the flange forgings can be placed inside the storage box 18, so that the flange forgings have a storage place and are very convenient to use.

[0027] A magnetic ring 30 is bonded to the surface of the movable rod 7, and a rubber sleeve 32 is fitted onto the surface of the movable rod 7. An iron ring 31 is bonded to one end of the rubber sleeve 32, and the other end of the iron ring 31 is attached to the magnetic ring 30. By installing the rubber sleeve 32, the friction between the movable rods 7 of the flange forging can be increased, thereby improving the stability of the flange forging after it is fixed, resulting in strong stability during use.

[0028] A fixing plate 19 is welded to the top of the base plate 1, and a first external threaded rod 20 is welded to the side of the storage box 18. The first external threaded rod 20 passes through the fixing plate 19, and a nut 21 is sleeved on the surface of the first external threaded rod 20. One end of the nut 21 is attached to the side of the fixing plate 19. By installing the first external threaded rod 20 and using the fact that the first external threaded rod 20 passes through the fixing plate 19, the nut 21 can be sleeved on the surface of the first external threaded rod 20, thereby fixing the storage box 18. This makes it very convenient to install and fix the storage box 18 on the base plate 1.

[0029] Side plates 26 are welded to the side of the storage box 18. A fixed base 27 is fixedly connected to the top of the side plate 26. A fixed frame 28 is fixedly connected to the other end of the fixed base 27. A handle 29 is welded to the surface of the fixed frame 28. By installing the handle 29, when it is necessary to move the storage box 18, the handle 29 can be used as the force point to move the storage box 18. It is very convenient to use.

[0030] A swivel ring 16 is welded to the top of the lead screw 14, and a gripping rod 17 is welded to the surface of the swivel ring 16. By installing the gripping rod 17, the lead screw 14 can be provided with a force point when rotating. The lead screw 14 can be rotated more conveniently by using the gripping rod 17, which is very labor-saving.

[0031] The bottom of the base plate 1 is bonded with an anti-slip pad 34, and the top of the base plate 1 is provided with a rubber sleeve 32. Anti-slip balls 33 are bonded to the surface of the rubber sleeve 32. The anti-slip balls 33 are evenly distributed. By installing the anti-slip pad 34, the friction between the base plate 1 and the workbench can be further increased, making the quality inspection clamping device for flange forgings more stable after being placed on the workbench, and the stability is stronger during use.

[0032] The side plates 26 are symmetrically distributed, and the fixing bases 27 are symmetrically distributed. The distribution of the side plates 26 ensures the stability of the fixing bracket 28, making the fixing bracket 28 more stable during use.

[0033] The working principle of the quality inspection clamping device for flange forgings is as follows: When using the quality inspection clamping device for flange forgings, the moving rod 7 and the limiting rod 8 should first be inserted through the interior of the flange forging. Then, the lead screw 14 is rotated. At this time, under the action of the bearing 15, the lead screw 14 can rotate in its original position. Subsequently, under the action of the internal thread seat 13, the slide plate can move up and down on the slide groove 3, thereby driving the moving rod 7 to move. At this time, through the expansion of the movement of the moving rod 7, the interior of the flange forging is supported, thus fixing the flange forging. It is very convenient to use, and the flange forging can then be inspected. Since the moving rod 7 and the limiting rod 8 are respectively connected to the first fixed column 5 and the second fixed column 6 through the rotating assembly, the rotating assembly can make the moving rod 7 and the limiting rod 8 have a rotational effect. When the flange forging is fixed on the moving rod 7 and the limiting rod 8, the moving rod 7 and the limiting rod 8 can be used to make the flange forging rotatable. This makes it more convenient to flip the flange forging during quality inspection. When a defective flange forging is detected during the use of the quality inspection clamping device for flange forging, the flange forging can be placed inside the storage box 18. Then, the second external thread rod 24 is used to penetrate the flange forging and embed it into the internal thread hole 23. At this time, the flange forging can be limited to the side of the partition 22 of the storage box 18. When another defective flange forging appears, it can be placed into the storage box 18 in sequence, and the second external thread rod 24 is rotated again until the second external thread rod 24 is embedded into the internal thread hole 23. It has a position for storing flange forgings and is very convenient to use.

[0034] It is understood that the present invention has been described through some embodiments, and those skilled in the art will recognize that various changes or equivalent substitutions can be made to these features and embodiments without departing from the spirit and scope of the invention. Furthermore, under the teachings of the present invention, these features and embodiments can be modified to adapt to specific situations and materials without departing from the spirit and scope of the invention. Therefore, the present invention is not limited to the specific embodiments disclosed herein, and all embodiments falling within the scope of the claims of this application are within the protection scope of the present invention.
