Description

Technical Field

[0001] This utility model relates to the technical field of oil storage tank processing equipment, and more specifically, to an auxiliary support mechanism for seam welding of oil storage tanks. Background Technology

[0002] As a core oil storage component in petroleum, chemical, and agricultural machinery equipment, oil storage tanks are mainly used to store fuel oil, lubricating oil, and other media. Their sealing performance and structural strength directly determine the operational safety of the equipment and the stability of the stored media. Since oil storage tanks are mostly cylindrical structures, in actual production, metal sheets are usually bent into a cylindrical shape using bending equipment, and then the butt joint of the cylinder is welded using a straight seam welding machine to form a complete closed cylinder. In this process, the seam welding process is a key link to ensure the sealing performance of the oil storage tank. If the oil storage tank is not positioned accurately or is not supported stably during welding, it is easy to cause misalignment of the butt joint and uneven weld, which can lead to oil leakage problems in later use. At the same time, support failure may also cause deformation of the oil storage tank during welding, reducing its structural load-bearing capacity. Therefore, it is necessary to use an auxiliary support mechanism in conjunction with a straight seam welding machine to achieve stable positioning and support of the oil storage tank.

[0003] In actual production, certain problems exist. On the one hand, existing support plates are mostly fixed or only easily adjustable, and cannot accurately adjust the support position according to the different diameter oil reservoirs formed by bending metal patches. For small-diameter oil reservoirs, insufficient support area can lead to tilting, while for large-diameter oil reservoirs, excessive compression can cause pre-deformation. It may also lead to displacement under welding vibration, causing misalignment of the butt joint. On the other hand, uneven clamping force may occur during the welding process of the oil reservoir. Insufficient clamping force cannot effectively limit the lateral movement of the oil reservoir, while excessive clamping can cause local deformation of the bent cylinder, damaging the flatness of the butt joint, and ultimately affecting the weld quality and the sealing performance of the oil reservoir. Therefore, we urgently need an auxiliary support mechanism for oil reservoir seam welding to solve the above problems. Utility Model Content

[0004] One objective of this invention is to provide a new technical solution for an auxiliary support mechanism for seam welding of oil storage tanks. By using the insertion hole of the arc-shaped plate to cooperate with the support plate and the rotating rod to adjust the angle of the sleeve piston rod, precise support and stable clamping of oil storage tanks of different diameters can be achieved, avoiding tilting and deformation and ensuring the quality of the weld.

[0005] According to a first aspect of this utility model, an auxiliary support mechanism for seam welding of an oil storage tank is provided, including a straight seam welding machine body and a positioning rod fixedly connected to the straight seam welding machine body for positioning the gap of the oil storage tank. The mechanism further includes: an arc-shaped plate bolted to the positioning rod for connection; the arc-shaped plate has equidistant insertion holes for positioning along its arc; a support plate for supporting the oil storage tank is provided on the arc-shaped plate; when the connection of the support plate is inserted into the insertion hole, an installation area is formed; and a rotating rod rotatably connected to the bottom of the arc-shaped plate, the end of which is provided with a tensioning plate for auxiliary support; when the tensioning surface of the tensioning plate abuts against the side of the oil storage tank, a tensioning area is formed.

[0006] Optionally, a damping pad for increasing friction is fixedly installed inside the insertion hole.

[0007] Optionally, the support plate is provided with at least three sets of arc-shaped grooves for adapting to the size of the oil reservoir, and the inner wall of the arc-shaped grooves is attached with silicone pads for anti-slip.

[0008] Optionally, the rotating rod is rotatably connected to a round rod on the protrusion at the bottom of the arc plate. A crossbar is symmetrically installed on the arc plate. A first limiting hole can be opened on the crossbar. When the positioning hole on the rotating rod is coaxial with the first limiting hole, it is locked by a bolt rod.

[0009] Optionally, a sleeve is bolted to the end of the rotating rod, and a piston rod for extension is slidably connected inside the sleeve. The clamping plate is bolted to the end of the piston rod.

[0010] Optionally, the piston rod is provided with multiple sets of second limiting holes linearly and equidistantly along its length direction. When the second limiting holes are coaxial with the positioning holes on the sleeve, they are locked by bolts.

[0011] 1. According to one embodiment of this disclosure, the auxiliary support mechanism for seam welding of the oil reservoir uses multiple sets of insertion holes on the arc plate to cooperate with the support plate. Combined with the arc grooves on the support plate that are adapted to different diameters and the silicone pads on the inner wall, it can accurately adjust the support position according to the oil reservoirs of different diameters formed by bending the metal patch, avoiding the tilting of small-diameter oil reservoirs and the easy deformation of large-diameter oil reservoirs. It can also increase friction through the silicone pads to prevent the oil reservoirs from sliding. At the same time, the damping pads in the insertion holes can prevent the support plate from shifting due to welding vibration. This effectively solves the problems of poor adaptability and easy shifting of existing support plates, and ensures the positioning accuracy of the oil reservoir seam.

[0012] 2. According to one embodiment of this disclosure, the auxiliary support mechanism for seam welding of the oil reservoir provides an angle adaptation basis for the sleeve and piston rod by rotating the rotating rod around the arc plate. The rotation angle is locked by the first limiting hole on the crossbar, and the extension length is precisely adjusted by multiple sets of second limiting holes on the piston rod. The clamping angle and force of the clamping plate can be flexibly controlled according to the diameter of the oil reservoir. This avoids the lateral movement of the oil reservoir caused by insufficient clamping force, and also prevents the bending and local deformation of the cylinder caused by excessive clamping force. This solves the defect of uneven clamping force in the prior art and ensures the uniformity of the weld and the sealing performance of the oil reservoir.

[0017] Various exemplary embodiments of the present invention will now be described in detail with reference to the accompanying drawings. It should be noted that, unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps set forth in these embodiments do not limit the scope of the present invention.

[0018] The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the invention or its application or use.

[0019] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and equipment should be considered part of the specification.

[0020] In all the examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values.

[0021] like Figure 1-5 As shown, an auxiliary support mechanism for seam welding of an oil storage tank includes a straight seam welding machine body 1 and a positioning rod 2 fixedly connected to the straight seam welding machine body 1 for positioning the gap of the oil storage tank.

[0022] Here, the straight seam welding machine body 1 is a welding device specifically designed for welding straight butt joints of metal workpieces. It is widely used in the production of cylindrical or rectangular metal components such as oil storage tanks, pipes, and pressure vessels. Its core function is to apply welding energy, such as electric arc or resistance heat, to the straight butt joint of the workpiece through an electrode or welding torch, and in conjunction with the wire feeding and traveling mechanism, to achieve continuous and uniform welding of the butt joint, ensuring the sealing performance and structural strength of the weld. This is a direct reference to a conventional technical solution, and will not be elaborated further here.

[0023] Taking this embodiment as an example, after the oil reservoir is bent into a circle by the metal patch, its butt joint is straight. At this time, the straight seam welding machine body 1 can accurately weld the butt joint through its built-in positioning, clamping and welding system. In addition, the straight seam welding machine usually has adjustable welding parameters such as welding current, voltage and welding speed, which can be adjusted according to the metal material, workpiece thickness and other factors to meet the welding requirements of different oil reservoirs. It is the core welding equipment in the process of processing the oil reservoir from the metal patch to the complete cylinder.

[0024] It also includes an arc-shaped plate 3 bolted to the positioning rod 2 for connection. The arc-shaped plate 3 has equidistant insertion holes 4 for positioning along its arc. A damping pad 8 for improving friction is fixedly installed in the insertion holes 4.

[0025] Here, the arc plate 3 is connected to the positioning rod 2 by bolts. The insertion holes 4 are opened at equal intervals along the arc, so that the support plate 5 can be inserted into different holes to realize the arc trajectory adjustment of the support position. For small-diameter oil storage cylinders, the support plate 5 is inserted into the inner insertion hole 4 to increase the support area and avoid tilting. For large-diameter oil storage cylinders, it is inserted into the outer insertion hole 4 to reduce support compression and avoid pre-deformation, effectively adapting to the processing requirements of bending metal patches into cylinders of different diameters.

[0026] Furthermore, the damping pad 8 inside the insertion hole 4 can increase the friction between the support plate 5 and the insertion hole 4, so that even under the high-frequency vibration of the straight seam welding machine body 1, the support plate 5 can be prevented from shifting, avoiding misalignment between the butt joint and the positioning rod 2, thus solving the vibration displacement defect in the prior art.

[0027] The arc plate 3 is provided with a support plate 5 for supporting the oil storage tank. The support plate 5 has at least three sets of arc grooves 9 for adapting to the size of the oil storage tank. The inner wall of the arc groove 9 is attached with a silicone pad 10 for anti-slip. When the connection of the support plate 5 is inserted into the insertion hole 4, an installation area is formed.

[0028] Here, at least three sets of arc-shaped grooves 9 on the support plate 5 correspond to the outer arc of oil storage cylinders of different diameters, so that when the oil storage cylinder contacts the support plate 5, they form a surface fit rather than a point contact, which further improves the support stability; multiple specifications of oil storage cylinders can be adapted without replacing the support plate 5, reducing production changeover costs.

[0029] Furthermore, the silicone pad 10 on the inner wall of the arc groove 9 can increase the friction coefficient between the oil reservoir and the support plate 5, preventing the oil reservoir from sliding along the arc groove 9 during welding. On the other hand, the silicone pad 10 has a certain elasticity, which can buffer the hard contact between the oil reservoir and the support plate 5, prevent the cylindrical surface from being scratched after the metal patch is bent, and reduce the transmission of welding vibration to the oil reservoir, thus protecting the cylinder structure.

[0030] A rotating rod 6 is rotatably connected to the bottom of the arc plate 3. The rotating rod 6 is rotatably connected to the round rod at the protrusion at the bottom of the arc plate 3. A crossbar 11 is symmetrically installed on the arc plate 3. A first limiting hole 12 can be opened on the crossbar 11. When the positioning hole on the rotating rod 6 is coaxial with the first limiting hole 12, it is locked by a bolt. The end of the rotating rod 6 is provided with a tensioning plate 7 for auxiliary support. When the tensioning surface of the tensioning plate 7 abuts against the side of the oil reservoir, a tensioning area is formed.

[0031] Here, the function of the rotating rod 6 is to provide an angle adjustment space for the sleeve 13 and piston rod 14 to adapt to oil reservoirs of different diameters by rotating around the bottom round rod of the arc plate 3. For small-diameter oil reservoirs, the rotating rod 6 needs to increase the rotation angle to drive the sleeve 13 and piston rod 14 closer to the oil reservoir, so that the pressing plate 7 can accurately fit the side of the oil reservoir. For large-diameter oil reservoirs, the rotating rod 6 needs to decrease the rotation angle to avoid the sleeve 13 and piston rod 14 from shifting due to improper angle. The first limiting hole 12 on the crossbar 11, in conjunction with the bolt rod, can fix the rotating rod 6 at the target angle that is suitable for the sleeve 13 and piston rod 14, preventing welding vibration from causing the angle of the rotating rod 6 to shift, and ensuring the stability of the adjusted position of the sleeve 13 and piston rod 14.

[0032] A sleeve 13 is bolted to the end of the rotating rod 6. A piston rod 14 for extension is slidably connected inside the sleeve 13. The clamping plate 7 is bolted to the end of the piston rod 14. Multiple sets of second limiting holes 15 are linearly and equidistantly opened on the piston rod 14 along its length direction. When the second limiting holes 15 are coaxial with the positioning holes on the sleeve 13, they are locked by bolts.

[0033] Here, based on the stable angle adjusted by the rotating rod 6, the sliding fit between the sleeve 13 and the piston rod 14 can precisely adjust the distance between the clamping plate 7 and the side of the oil reservoir. The multiple sets of second limiting holes 15 on the piston rod 14 can be locked by bolt rods after being adjusted to the appropriate length, avoiding the problem of inaccurate length control when manually tightening bolts in the prior art. This ensures that the clamping force is not too small and the oil reservoir will not move laterally due to the piston rod 14 extending too short, nor will the clamping force be too large and the cylinder will not be bent and deformed locally due to the piston rod 14 extending too long, thus ensuring uniform and stable clamping force and guaranteeing the flatness of the joint.

[0034] In this invention, the position of the insertion hole 4 on the support plate 5 is selected according to the diameter of the oil reservoir formed by bending the metal patch. When the diameter is small, it is inserted into the inner insertion hole 4; when the diameter is large, it is inserted into the outer insertion hole 4. After insertion, the damping pad 8 inside the insertion hole 4 achieves initial anti-loosening. The oil reservoir is placed in the corresponding arc-shaped groove 9 of the support plate 5. The silicone pad 10 on the inner wall of the arc-shaped groove 9 fits against the outer wall of the oil reservoir to achieve anti-slip positioning. At the same time, the oil reservoir joint is aligned with the preset alignment point on the positioning rod 2, and it is pressed by the clamping device on the straight seam welding machine body 1. At this time, the rotating rod 6 is rotated to adjust the oil reservoir diameter to match the cylinder 13 and piston rod. Angle 14 is adjusted so that sleeve 13 and piston rod 14 are aligned with the side of oil reservoir. When the positioning hole on rotating rod 6 is coaxial with the first limiting hole 12 of cross rod 11, insert bolt rod to lock the angle of rotating rod 6. Then pull piston rod 14 so that the pressing plate 7 forms a moderate pressing force with the side of oil reservoir. When the second limiting hole 15 on piston rod 14 is coaxial with the positioning hole of sleeve 13, insert bolt rod to lock the length of piston rod 14. Start straight seam welding machine body 1 to weld the butt joint of oil reservoir. During the welding process, support plate 5 and arc groove 9 provide stable support, and pressing plate 7 provides lateral limiting to ensure that oil reservoir does not shift or deform and the weld is uniform and flat.
