[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0017] Please see Figures 1-4 In this embodiment of the utility model, a flange inspection fixture structure includes a mounting plate 1. An adjustment mechanism extending to the bottom of the mounting plate 1 is provided on the top of the mounting plate 1. A worm gear 15 for driving the adjustment action is rotatably mounted on the bottom end of the mounting plate 1. A forward and reverse motor 16 coaxially connected to the worm gear 15 is mounted on the bottom end of the mounting plate 1. A limiting mechanism is installed on the top of the mounting plate 1 to limit the expansion of the adjustment mechanism. A hollow plug gauge 9 is sleeved on the position above the adjustment mechanism on the mounting plate 1. A support ring 10 is integrally formed on the outer wall of the hollow plug gauge 9.

[0018] In this embodiment: First, before using the hollow plug gauge 9 to inspect the mounting holes of the flange, the limiting mechanism is adjusted according to the diameter of the flange. After adjustment, the forward and reverse motor 16 is started, which drives the worm gear 15 to rotate. The rotating worm gear 15 can drive the adjusting mechanism to lock inward or expand outward, so as to achieve the purpose of synchronous movement of multiple hollow plug gauges 9 until the hollow plug gauge 9 contacts and squeezes the limiting mechanism. After receiving the pressure, the limiting mechanism sends an electrical signal to the controller, which can then control the forward and reverse motor 16 to stop running. After that, the flange to be inspected can be connected with the hollow plug gauge 9 to observe whether there is misalignment or inconsistency between the size and processing standard of the mounting holes of the flange.

[0019] Before testing, a corresponding hollow plug gauge 9 can be selected and connected to the output end of the adjustment mechanism according to the size of the flange mounting hole. In this way, the mounting hole testing of flanges of different specifications can be satisfied.

[0020] Please refer to this carefully. Figure 1 , Figure 2 and Figure 3 The adjustment mechanism includes a rotating ring 11 rotatably mounted on the bottom of the mounting plate 1. The rotating ring 11 has multiple arc-shaped grooves 12 equidistantly spaced on its inner circumference. The mounting plate 1 has multiple straight grooves 2 equidistantly spaced on its inner circumference. The multiple arc-shaped grooves 12 correspond one-to-one with the multiple straight grooves 2. The inner wall of the straight groove 2 is movably connected to a movable rod 13 that extends through to the top of the mounting plate 1. The outer wall of the movable rod 13 located above the mounting plate 1 is sleeved with a hollow plug gauge 9. The bottom end of the rotating ring 11 is integrally formed with a hollow worm gear 14 that meshes with the worm 15.

[0021] In this embodiment: when the worm gear 15 rotates, the worm gear 15 drives the hollow worm wheel 14 to rotate. When the hollow worm wheel 14 rotates, it synchronously drives the rotating ring 11 to rotate. At this time, multiple arc-shaped grooves 12 rotate synchronously. When the arc-shaped grooves 12 rotate, they squeeze the movable rod 13 connected to them. The compressed movable rod 13 moves along the straight groove 2, realizing that multiple movable rods 13 move synchronously inward or outward, thereby realizing the synchronous movement of the hollow plug gauge 9 outside the movable rod 13.

[0022] Please refer to this carefully. Figure 1 and Figure 4 The limiting mechanism includes a guide rail 3 installed on the top of the mounting plate 1 and parallel to a straight groove 2. Two sliders 5 are slidably installed inside the guide rail 3. One end of each slider 5 extends through to the outside of the guide rail 3 and is fixedly installed with a mounting box 6. The two mounting boxes 6 are symmetrically distributed. The limiting mechanism also includes a sliding plate 21 slidably installed inside the mounting box 6. One end of the sliding plate 21 has an integrally formed moving head 22 extending through to the outside of the mounting box 6. The other end of the sliding plate 21 has an integrally formed extrusion head 18 protruding outward at its center. One end of the inner wall of the mounting box 6 is equipped with a pressure sensor 19 aligned with the extrusion head 18. The pressure sensor 19 is electrically connected to the forward and reverse motor 16 via a controller. A guide rod 20 is fixedly installed between the two ends of the inner wall of the mounting box 6. The sliding plate 21 is slidably connected to the guide rod 20. One end of the sliding plate 21 and one end of the inner wall of the mounting box 6 are equipped with a return spring 17 that is sleeved with the guide rod 20.

[0023] In this embodiment: Before starting the forward and reverse motor 16, according to the size of the mounting hole of the flange to be tested, the corresponding hollow plug gauge 9 is selected and the corresponding hollow plug gauge 9 is sleeved on the outside of the movable rod 13. Then, according to the diameter of the flange, it is determined whether the multiple hollow plug gauges 9 need to move inward or outward. If they need to move inward or outward, the mounting box 6 in the corresponding direction is adjusted. The mounting box 6 drives the slider 5 to slide inside the guide rail 3. According to the millimeter scale 8, the position of the mounting box 6 is determined. After moving to the accurate position, the position of the slider 5 is fixed.

[0024] As the hollow plug gauge 9 moves, it gradually approaches the mounting box 6 and presses against the moving head 22. The moving head 22 moves along the guide rod 20 under force. At this time, the return spring 17 is compressed until one end of the moving head 22 outside the mounting box 6 is flush with one end of the mounting box 6. At this time, the pressing head 18 abuts against the pressure sensor 19. The pressure sensor 19 sends an electrical signal to the controller, which can then control the forward and reverse motor 16 to stop running.

[0025] Please refer to this carefully. Figure 1The slider 5 has an upwardly protruding tightening member 7 connected to its internal thread. The top plate of the guide rail 3 has a strip groove 4 for the screw part of the tightening member 7 to slide. The top of the mounting plate 1 is engraved with millimeter scale 8 indicating the position of the mounting box 6.

[0026] In this embodiment: after the mounting box 6 is moved to the accurate position, the handle of the tightening member 7 is rotated, and the handle drives its screw to rotate. At this time, the screw is screwed downward until the handle is tightly pressed against the top of the guide rail 3. At this time, the position of the slider 5 cannot be moved, thus completing the position limitation of the mounting box 6.

[0027] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
