Description

Technical Field

[0001] This utility model relates to the field of flange processing technology, and in particular to a marking device for a ship hull piping flange. Background Technology

[0002] In the shipbuilding industry, the hull is constructed in sections, and the piping system needs to be prefabricated and installed simultaneously with the sections. In order to ensure that key information such as pipe section model and specifications can be quickly and accurately identified during on-site installation, clear markings must be made on the flange surface during the piping system fabrication stage.

[0003] Traditional piping flange marking relies on manual labor. Typically, an operator holds a letter mold, applies it to the flange face, and then uses a hammer to strike each mold individually to complete the stamping. This method has significant technical drawbacks: First, it is inefficient, requiring manual positioning of the mold and control of the hammering force, and since the stamp consists of multiple characters, striking each one is time-consuming. Second, the marking quality is inconsistent, depending on the operator's focus and skill; mold misalignment can lead to skewed or inverted markings, affecting subsequent recognition. Third, it poses significant safety hazards; improper hammering force or slippage of the mold can easily injure the hand, causing soft tissue contusions, bruising, or even finger fractures, seriously threatening the operator's safety.

[0004] To address the aforementioned technical deficiencies, Chinese Patent CN208101446U discloses a flange stamping machine. While this machine reduces wear and failure rates by replacing chain drive with a mechanical clamping structure, it still cannot meet the marking requirements of ship piping flanges: the rigid clamping mechanism requires additional power and cannot adapt to the shapes of different flange specifications; furthermore, the machine can only be adjusted in one direction, making it difficult to accurately align the marking area on the flange; and it lacks safety features for manual operation, still requiring manual assistance for positioning, thus failing to address the risk of hand injury. Therefore, the industry urgently needs a marking device that is compatible with ship piping flanges and balances safety and positioning accuracy. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of existing steel stamping machines, such as low safety and poor positioning accuracy, and to provide a marking device for ship hull piping flanges.

[0006] This utility model is achieved through the following technical solution: a ship hull piping flange marking device, comprising a base and a letterhead; lifting arms are respectively provided at both ends of the top of the base, and the tops of the two lifting arms are connected to a supporting beam; a sliding adjustment mechanism is provided on the supporting beam, and the letterhead is disposed on the sliding adjustment mechanism, which can adjust the position of the letterhead; a fixed column is provided at the center of the top of the base, and clamping units are symmetrically arranged on both sides of the fixed column, which can clamp and fix the position of the piping flange; the clamping unit includes a sliding arm, which slides through the lifting arms, and the sliding arm can move laterally on the lifting arms. The sliding arm is equipped with an arc-shaped support plate at one end near the fixed column, the top surface of which can abut against the bottom surface of the pipe flange. A telescopic spring is provided on the inner arc side of the arc-shaped support plate, with both ends connected to the inner arc surface of the arc-shaped support plate and the side surface of the fixed column, respectively. A fixed arm is provided on the sliding arm behind the arc-shaped support plate, and an arc-shaped clamping plate is provided at the top of the fixed arm behind the arc-shaped support plate. The curvature of the arc-shaped support plate and the arc-shaped clamping plate is adapted to the pipe flange, forming a space between them to accommodate the side of the pipe flange. The telescopic spring allows the two arc-shaped clamping plates to clamp the fixed pipe flange.

[0007] This device achieves elastic clamping through a telescopic spring, requiring no additional power drive. It can adapt to different specifications of pipe flanges and is suitable for prefabricated marine piping systems. At the same time, the mechanically fixed letterhead avoids manual handling of the letter mold, eliminating the risk of hand injury from hammering. Furthermore, the arc-shaped support plate and arc-shaped clamping plate work together to ensure stable flange clamping, solving the problems of existing technologies that cannot adapt to pipe flanges and lack safety protection.

[0008] A further improvement of this utility model is that the sliding adjustment mechanism includes a plurality of sliders, the sliders being slidably connected to the support beam, and the sliders being able to move laterally on the support beam; each slider has a slide plate at its bottom, one end of the slide plate being slidably connected to the bottom of the slider, the other end of the slide plate being connected to the letterhead, and the slide plate being able to move longitudinally on the slider.

[0009] A further improvement of this utility model is that the slider has a through groove A, and the slider is slidably sleeved on the support beam through the through groove A; one end of the bottom of the slider has a slot A located below the through groove A, and the end of the slide plate is slidably inserted into the slider through the slot A; a positioning screw A that cooperates with the support beam is screwed onto the top surface of the slider, and the positioning screw A can fix the position of the slider; a positioning screw B that cooperates with the slide plate is screwed onto the bottom surface of the slider, and the positioning screw B can fix the position of the slide plate.

[0010] A further improvement of this utility model is that the letterhead is detachably connected to the slide plate by bolts.

[0011] A further improvement of this utility model is that the lifting arm includes a fixed plate, the top of which has a slot B, and the bottom of which is connected to the top of the base; a lifting plate is provided on the top of the fixed plate, the top of which is connected to the support beam, and the bottom of which is slidably inserted into the fixed plate through the slot B; a positioning screw C that cooperates with the lifting plate is screwed onto the outer side of the fixed plate, and the positioning screw C can fix the position of the lifting plate.

[0012] A further improvement of this utility model is that the fixing plate has a through groove B located on one side of the slot B, and the fixing plate is slidably sleeved on the sliding arm through the through groove B.

[0013] A further improvement of this utility model is that the through groove B and the sliding arm are mutually adapted square structures.

[0014] A further improvement of this utility model is that the top surface of the arc-shaped support plate and the bottom surface of the arc-shaped clamping plate are located on the same plane, and the top surface of the arc-shaped clamping plate is located below the top surface of the pipe flange.

[0015] As can be seen from the above technical solutions, the beneficial effects of this utility model are: 1. This device uses a fixed column, symmetrical clamping units, and telescopic springs to form an elastic clamping structure. It can adapt to different specifications of pipe flanges without additional power, solving the problem that the existing rigid drive clamping structure cannot adapt to pipe flanges and relies on drive components. At the same time, the mechanical fixation of the letterhead avoids manual holding and hammering of the letter mold, eliminating the risk of hand injury and filling the gap in the existing technology in terms of operational safety protection.

[0016] 2. This device achieves horizontal, vertical, and height positioning of the letterhead by moving the slider laterally and the slide plate longitudinally through the sliding adjustment mechanism, combined with the height adjustment of the lifting arm, thus avoiding the flange bolt holes. The detachable letterhead also allows for quick character replacement, solving the problems of low efficiency and large deviation caused by the single-direction adjustment and inconvenient letterhead replacement in existing steel stamping machines.

[0017] 3. This device uses a square through-slide groove B on a fixed plate to cooperate with the sliding arm, which can prevent the sliding arm from rotating and shifting. The arc-shaped support plate and the arc-shaped clamping plate provide planar support, which can avoid the flange from deforming under stress. Compared with the existing technology, which is prone to damaging the flange due to rigid clamping and insufficient guiding accuracy, this device is more in line with the stability and accuracy requirements of ship piping flanges.

[0022] To make the objectives, features, and advantages of this utility model more apparent and understandable, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings of the specific embodiments. Obviously, the embodiments described below are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this patent, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this patent.

[0023] Now refer to Figure 1 and 2The following is a description of a specific embodiment: The present invention provides a ship hull piping flange marking device, comprising a base 1 and a letterhead 5; lifting arms 2 are respectively provided at both ends of the top of the base 1, and the tops of the two lifting arms 2 are connected to a supporting beam 3; a sliding adjustment mechanism 4 is provided on the supporting beam 3, and the letterhead 5 is disposed on the sliding adjustment mechanism 4, which can adjust the position of the letterhead 5; a fixed column 6 is provided at the center of the top of the base 1, and symmetrically arranged clamping units 7 are respectively provided on both sides of the fixed column 6, which can clamp and fix the position of the piping flange; the clamping unit 7 includes a sliding arm 701, which slides through the lifting arms 2, and can move laterally on the lifting arms 2; the sliding arm 701 rests against... An arc-shaped support plate 702 is provided at one end near the fixed column 6, and the top surface of the arc-shaped support plate 702 can abut against the bottom surface of the pipe flange. A telescopic spring 8 is provided on the inner arc side of the arc-shaped support plate 702, and the two ends of the telescopic spring 8 are respectively connected to the inner arc surface of the arc-shaped support plate 702 and the side surface of the fixed column 6. A fixed arm 703 is provided on the sliding arm 701 behind the arc-shaped support plate 702, and an arc-shaped clamping plate 704 is provided on the top of the fixed arm 703 behind the arc-shaped support plate 702. The curvature of the arc-shaped support plate 702 and the arc-shaped clamping plate 704 is adapted to the pipe flange, and a placement space 705 for accommodating the side of the pipe flange can be formed between the arc-shaped support plate 702 and the arc-shaped clamping plate 704. The telescopic spring 8 enables the two arc-shaped clamping plates 704 to clamp and fix the pipe flange.

[0024] In use, first pull the sliding arm 701 of the clamping unit 7 to move it laterally along the lifting arm 2 to expand the clamping space. Place the hull piping flange in the placement space 705 of the clamping unit 7 on both sides of the fixed column 6, ensuring that the top surface of the arc-shaped support plate 702 is against the bottom surface of the flange. After releasing the sliding arm 701, the telescopic spring 8 releases its elastic force, driving the sliding arm 701 to reset, so that the arc-shaped clamping plates 704 on both sides cooperate with the arc-shaped support plate 702 to clamp the flange, achieving elastic adaptive fixing of piping flanges of different specifications. Then, adjust the position of the letterhead 5 through the sliding adjustment mechanism 4, and adjust the height of the support beam 3 through the lifting arm 2, so that the letterhead 5 is aligned with the flange marking area. Tapping the letterhead 5 will complete the marking. Finally, pull the sliding arm 701 to remove the flange.

[0025] This device achieves elastic clamping through the telescopic spring 8, requiring no additional power drive. It can adapt to different specifications of pipe flanges and is suitable for prefabricated marine piping systems. At the same time, the mechanically fixed letterhead 5 avoids manual handling of the letter mold, eliminating the risk of hand injury from hammering. Furthermore, the arc-shaped support plate 702 and the arc-shaped clamping plate 704 work together to ensure stable flange clamping, solving the problems of existing technologies that cannot adapt to pipe flanges and lack safety protection.

[0026] Specifically, refer to Figure 2 The sliding adjustment mechanism 4 includes several sliders 401, which are slidably connected to the support beam 3 and can move laterally on the support beam 3. Each slider 401 has a slide plate 402 at its bottom. One end of the slide plate 402 is slidably connected to the bottom of the slider 401, and the other end of the slide plate 402 is detachably connected to the letterhead 5 by a bolt 501. The slide plate 402 can move longitudinally on the slider 401.

[0027] When adjusting the position of the prefix 5, push the slider 401 to slide laterally along the support beam 3, which can cause the prefix 5 to move laterally to align with different lateral marking areas of the flange; push the slide plate 402 to slide longitudinally along the bottom of the slider 401, which can cause the prefix 5 to move longitudinally to avoid areas such as flange bolt holes; the prefix 5 is detachably connected to the slide plate 402 by bolts 501. When the marking character needs to be replaced, the prefix 5 can be replaced by removing the bolts 501.

[0028] This device can achieve bidirectional adjustment of the letterhead 5 in both horizontal and vertical directions through a sliding adjustment mechanism, which provides greater positioning flexibility and can accurately adapt to the complex marking requirements of pipe system flanges. The detachable letterhead 5 design improves the device's versatility and solves the problems of insufficient adjustment dimensions and inconvenient letterhead replacement in existing technologies.

[0029] Specifically, refer to Figure 2 The slider 401 has a through groove A403, through which it is slidably fitted onto the support beam 3. One end of the bottom of the slider 401 has a slot A404 located below the through groove A403, through which the end of the slide plate 402 is slidably inserted into the slider 401. A positioning screw A405, which mates with the support beam 3, is screwed onto the top surface of the slider 401, fixing its position. A positioning screw B, which mates with the slide plate 402, is screwed onto the bottom surface of the slider 401, fixing its position.

[0030] The slider 401 is slidably connected to the support beam 3 through the through groove A403, ensuring smooth lateral sliding of the slider 401. After adjusting to the target position, tighten the positioning screw A405 to press against the support beam 3, thus fixing the position of the slider 401. The slide plate 402 is slidably connected to the slider 401 through the slot A404, ensuring stable longitudinal sliding of the slide plate 402. After adjusting to the target position, tighten the positioning screw B to press against the slide plate 402, thus fixing the position of the slide plate 402.

[0031] This device allows the slider 401 and slide plate 402 to slide smoothly without jamming through the cooperation of the through groove A403 and the slot A404. The positioning screws A405 and B can quickly lock the position. Compared with the existing technology where the screw adjustment only relies on self-locking, this device has more accurate and stable positioning, avoids the offset of the letter 5 during the marking process, ensures the consistency of the marking position of the pipe flange, and improves the marking quality.

[0032] Specifically, refer to Figure 2 The lifting arm 2 includes a fixed plate 201, the top of which has a slot B203, and the bottom of which is connected to the top of the base 1. A lifting plate 202 is provided on the top of the fixed plate 201, the top of which is connected to the support beam 3, and the bottom of which is slidably inserted into the fixed plate 201 through the slot B203. A positioning screw C that cooperates with the lifting plate 202 is screwed onto the outer side of the fixed plate 201, and the positioning screw C can fix the position of the lifting plate 202.

[0033] When adjusting the height of letterhead 5, loosen the positioning screw C and push the lifting plate 202 to slide up and down along the slot B203 of the fixing plate 201, thereby driving the support beam 3 and letterhead 5 to rise and fall synchronously, so that letterhead 5 is close to or away from the flange; after adjusting to the target height—such as when letterhead 5 is close to the flange or away from the mark—tighten the positioning screw C to make it press against the lifting plate 202 and fix the position of the lifting plate 202.

[0034] Compared to the existing technology that only adjusts the distance between the stamping machine and the worktable by adjusting the screw, this device achieves rapid height adjustment by using slot B203 in conjunction with lifting plate 202. It is more convenient to operate, can be adapted to hull piping flanges of different thicknesses, and does not require disassembly for adjustment, thus improving the marking efficiency in the prefabrication of ship piping systems.

[0035] Specifically, refer to Figure 2 The fixing plate 201 has a through groove B204 located on one side of the slot B203, and the fixing plate 201 is slidably sleeved on the sliding arm 701 through the through groove B204.

[0036] The sliding arm 701 passes through the through groove B204 of the fixed plate 201. When the sliding arm 701 is pulled, the sliding arm 701 moves laterally along the through groove B204, which drives the arc-shaped support plate 702 and the arc-shaped clamping plate 704 of the clamping unit 7 to move synchronously, thereby realizing the clamping and loosening of the flange. The through groove B204 provides lateral sliding guidance for the sliding arm 701 and limits the offset of the sliding arm 701.

[0037] This device provides stable guidance for the sliding arm 701 through the through groove B204, preventing the sliding arm 701 from tilting when moving. Compared with the existing technology that only guides the moving block through the base groove, this device provides more precise guidance, ensuring that the clamping unit 7 clamps the pipe flange accurately, preventing flange offset from affecting the marking, and improving stability.

[0038] In one embodiment, reference Figure 2 The through groove B204 and the sliding arm 701 are mutually compatible square structures. When the sliding arm 701 moves laterally along the through groove B204, the aforementioned square structure can restrict the sliding arm 701 from rotating around its own axis, ensuring that the sliding arm 701 drives the arc-shaped support plate 702 and the arc-shaped clamping plate 704 to always maintain the correct clamping posture, and avoid flange clamping misalignment due to the rotation of the sliding arm 701.

[0039] Compared to existing technologies that do not have an anti-rotation structure for sliding parts, the square structure of this device can effectively prevent rotation, ensuring that the clamping posture of the clamping unit 7 on the piping flange is stable, avoiding the skewed marking caused by misalignment of the flange during marking, further improving the marking accuracy, and meeting the high requirements of ship piping flanges for marking accuracy.

[0040] In one embodiment, reference Figure 2 The top surface of the arc-shaped support plate 702 and the bottom surface of the arc-shaped clamping plate 704 are located on the same plane, and the top surface of the arc-shaped clamping plate 704 is located below the top surface of the pipe flange.

[0041] The top surface of the arc-shaped support plate 702 and the bottom surface of the arc-shaped clamping plate 704 are on the same plane. When clamping the flange, the two together form a planar support, so that the flange is subjected to uniform force and avoids deformation of the flange due to uneven force. The top surface of the arc-shaped clamping plate 704 is located below the top surface of the piping flange, which can avoid the top surface area of ​​the flange and does not block the striking path of the letter 5, ensuring that the letter 5 can effectively contact the flange marking area.

[0042] Through the above-mentioned planar support design, this device can avoid flange clamping deformation, protect the accuracy of piping flanges, and solve the problem that rigid clamping may cause flange deformation in the prior art; the arc-shaped clamping plate 704 avoids the top surface of the flange, ensuring smooth marking operation, and can complete the tapping without adjusting the clamping position, improving marking efficiency and adapting to the practical needs of marking marine piping flanges.

[0043] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention.
