Description

Technical Field

[0001] This utility model relates to the field of pressure vessel manufacturing, and in particular to a tooling device for adjusting the center distance and end face parallelism of double flanges. Background Technology

[0002] A pressure vessel is a closed device that holds gas or liquid and withstands a certain pressure. It is a closed container with high safety requirements and mainly includes a shell, heads, nozzles, and seals. The shell is mostly cylindrical, but can also be spherical, and is the main part that bears the pressure. The heads come in various shapes such as spherical and elliptical. Nozzles are used for process and maintenance, such as manholes and material inlets and outlets. Seals are used to ensure the container's airtightness.

[0003] During the processing of equipment in pressure vessel equipment manufacturing plants, it is often necessary to install and weld the root flange of a double-flange float level gauge on the equipment body. This is because the float level gauge is purchased by the user who ordered the pressure vessel equipment and transported directly to the user's unit. The center distance and end face of the two flanges of the complete set of level gauges processed by the outsourced level gauge manufacturer have already ensured the corresponding accuracy requirements.

[0004] However, in pressure vessel factories, production workers often manually adjust the distance of the double flanges at the base of the liquid level gauge using a tape measure on the equipment body before drilling holes and welding the double flanges. This often results in unsatisfactory results, leading to problems such as inconsistent center distances, skewed angles, and non-parallel flange faces. Large deviations require rework, resulting in low production efficiency, wasting time, effort, and labor, and preventing timely completion of equipment products.

[0005] Therefore, it is necessary to provide a tooling device for adjusting the center distance and end face parallelism of double flanges to solve the above-mentioned technical problems. Utility Model Content

[0006] This utility model provides a tooling device for adjusting the center distance and end face parallelism of double flanges, which solves the problem that problems such as inconsistent center distance, skewed angle, and non-parallel flange end faces often occur when workers manually adjust the distance on the equipment body using a tape measure, resulting in large deviations.

[0007] To solve the above-mentioned technical problems, this utility model provides a tooling device for adjusting the center distance and end face parallelism of double flanges, including: a mounting frame, a lifting ring, a moving groove, a limiting device, flanges, and a limiting groove;

[0008] One end of the lifting ring is fixedly connected to one end of the mounting frame, the movable groove is opened inside the mounting frame, the flange is provided on one side of the mounting frame, and the limiting groove is opened inside the mounting frame;

[0009] The limiting device includes a limiting pin, a nut, and a limiting plate. The limiting pin is slidably connected to the inside of the limiting groove, the nut is threadedly connected to the surface of the limiting pin, and the limiting plate is fixedly installed on the surface of the limiting pin.

[0010] Preferably, one side of the movable groove is connected to one side of the limiting groove to form a through groove, and the nut is slidably connected inside the movable groove.

[0011] Preferably, the limiting plate is an irregular triangular pressure plate, and the limiting plate is welded to the surface of the limiting pin to form an L-shaped hook.

[0012] Preferably, the mounting frame is made of steel plate or steel beam / column with a width of 100mm, a thickness of 50mm, and a length of approximately 1000-3000mm.

[0013] Preferably, a support frame is fixedly connected to one side of the mounting frame, and two limiting rings are rotatably connected to one end of the support frame, with a fixing component inside the limiting ring.

[0014] Preferably, the fixing element is a bolt, and both limiting rings have threaded holes that are compatible with the bolt inside.

[0015] Preferably, the inner wall surfaces of both limiting rings are provided with multiple movable wheels, which are omnidirectional wheels.

[0016] Compared with related technologies, the tooling device provided by this utility model for adjusting the center distance and end face parallelism of double flanges has the following advantages:

[0017] This utility model provides a tooling device for adjusting the center distance and end face parallelism of two flanges. By using a mounting frame in conjunction with a moving groove, a limiting groove, and a limiting device, the flange is limited to a suitable position on the mounting frame.

[0023] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0024] First Embodiment

[0025] Please refer to the following: Figure 1 , Figure 2 and Figure 3 ,in, Figure 1 A schematic diagram of the structure of a first embodiment of a tooling device for adjusting the center distance and end face parallelism of double flanges provided by this utility model; Figure 2 for Figure 1 The diagram shows the structure of the limiting device. Figure 3 for Figure 1 The enlarged schematic diagram of part A is shown. A tooling device for adjusting the center distance and end face parallelism of double flanges includes: a mounting frame 1, a lifting ring 2, a moving groove 3, a limiting device 4, a flange 5, and a limiting groove 6;

[0026] One end of the lifting ring 2 is fixedly connected to one end of the mounting frame 1, the moving groove 3 is opened inside the mounting frame 1, the flange 5 is provided on one side of the mounting frame 1, and the limiting groove 6 is opened inside the mounting frame 1.

[0027] The limiting device 4 includes a limiting pin 41, a nut 42, and a limiting plate 43. The limiting pin 41 is slidably connected to the inside of the limiting groove 6, the nut 42 is threadedly connected to the surface of the limiting pin 41, and the limiting plate 43 is fixedly installed on the surface of the limiting pin 41.

[0028] The limiting pin 41 is a bolt, and the nut is threadedly connected to the surface of the limiting pin 41. When the nut 42 is rotated to one side, the surface of the bolt moves to one side. When one side of the nut 42 contacts the surface of the moving groove 3, it limits the limiting plate 43, thereby limiting the flange 5.

[0029] The limiting groove 6 and the moving groove 3 are used to allow the limiting pin 41 to move to one side and adjust the position of the limiting plate 43, so as to conveniently limit the flange 5 in a suitable position and adjust the distance between the two flanges 5.

[0030] Both sides of the mounting bracket 1 are equipped with scales to facilitate the adjustment of the distance between the two flanges 5.

[0031] One side of the movable groove 3 is connected to one side of the limiting groove 6 to form a through groove, and the nut 42 is slidably connected inside the movable groove 3.

[0032] The limiting plate 43 is an irregular triangular pressure plate, and the limiting plate 43 is welded to the surface of the limiting pin 41 to form an L-shaped hook.

[0033] The mounting frame 1 is made of steel plate or steel beam with a width of 100mm, a thickness of 50mm, and a length of about 1000-3000mm.

[0034] The working principle of the tooling device for adjusting the center distance and end face parallelism of double flanges provided by this utility model is as follows:

[0035] In use, after placing the flange 5 in a suitable position on one side of the mounting bracket 1, the limiting plate 43 is moved to the surface of the flange 5, and the nut 42 is rotated to one side, thereby moving to one side on the surface of the limiting pin 41 to limit the limiting plate 43.

[0036] After placing another flange 5 at a certain distance between the mounting bracket 1 and the previous flange 5 on the same side according to the scale on the mounting bracket 1, the limiting plate 43 is moved to one side to the surface of the flange 5, and the limiting plate 43 is limited by the nut 42 and the limiting pin 41.

[0037] After installing the two flanges 5, the mounting bracket 1 is lifted and moved to the appropriate position using the lifting ring 2.

[0038] Compared with related technologies, the tooling device provided by this utility model for adjusting the center distance and end face parallelism of double flanges has the following advantages:

[0039] This utility model provides a tooling device for adjusting the center distance and end face parallelism of two flanges. By using the mounting frame 1 in conjunction with the moving groove 3, the limiting groove 6 and the limiting device 4, the flange 5 is limited to a suitable position on the mounting frame 1. The mounting frame 1 is then suspended to one side of the pressure vessel by the lifting ring 2, so that the two flanges 5 are at the same level and the distance between them is fixed. This prevents the center distance between the two flanges 5 from being inconsistent, the angle from being skewed, and the flange end faces from being non-parallel when welding the flanges 5. This improves the welding effect and increases work efficiency.

[0040] Second Embodiment

[0041] Please refer to the following: Figure 4 Based on the tooling device for adjusting the center distance and end face parallelism of double flanges provided in the first embodiment of this application, the second embodiment of this application proposes another tooling device for adjusting the center distance and end face parallelism of double flanges. The second embodiment is merely a preferred embodiment of the first embodiment, and the implementation of the second embodiment will not affect the separate implementation of the first embodiment.

[0042] Specifically, the second embodiment of this application provides a tooling device for adjusting the center distance and end face parallelism of double flanges, which differs in that it also includes a support frame 7, the support frame 7 is fixedly connected to one side of the mounting frame 1, and one end of the support frame 7 is rotatably connected to two limiting rings 8, and the limiting rings 8 are provided with fixing members 9 inside.

[0043] One side of each of the two limiting rings 8 is rotatably connected to the inside of the support frame 7. This is used to limit the mounting frame 1 after the two limiting rings 8 rotate and merge to one side, thereby preventing the mounting frame 1 from shaking to one side and shifting its position.

[0044] The fixing element 9 is a bolt, and the two limiting rings 8 each have a threaded hole that matches the bolt.

[0045] After the two limiting rings 8 are combined, the two limiting rings 8 are limited by installing bolts into the threaded holes.

[0046] The inner wall surfaces of the two limiting rings 8 are each provided with a plurality of movable wheels 10, and the movable wheels 10 are omnidirectional wheels.

[0047] Multiple casters 10 are used to reduce the friction between the limiting ring 8 and the pressure vessel, while also protecting the pressure vessel and facilitating the movement of the limiting ring 8.

[0048] The working principle of the tooling device for adjusting the center distance and end face parallelism of double flanges provided by this utility model is as follows:

[0049] In use, the mounting bracket 1 is limited by rotating the two limiting rings 8 to one side and then installing the fixing piece 9.

[0050] When the mounting frame 1 moves, it drives multiple moving wheels 10 to move as well.

[0051] Compared with related technologies, the tooling device provided by this utility model for adjusting the center distance and end face parallelism of double flanges has the following advantages:

[0052] This utility model provides a tooling device for adjusting the center distance and end face parallelism of double flanges. The support frame 7, together with the limiting ring 8, the fixing part 9 and multiple moving wheels 10, limits the mounting frame 1, thereby preventing the mounting frame 1 from shaking to one side and causing positional deviation.

[0053] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
