Description

TECHNICAL FIELD

[0001] The present application relates to the field of laser welding of thin-walled metal pipe fittings, in particular to a thin-walled hardware laser processing anti-deformation device. BACKGROUND

[0002] In industrial practice, thin-walled hardware is generally considered to have a wall thickness to diameter (or characteristic size) ratio of usually 1:10 to 1:20 or even smaller. Large-diameter thin-walled metal pipe fittings, with the advantages of lightweight and high efficiency, are widely used in aerospace, petrochemical, new energy vehicle, municipal engineering and other fields, and are key components of rocket fuel pipes, oil and gas transmission pipes, cooling pipelines and other core systems. However, the laser welding of such pipe fittings has long been plagued by the problem of uncontrolled deformation, which has become a core bottleneck restricting product precision, qualification rate and industrial application.

[0003] The instantaneous high temperature of laser welding can cause the weld area to expand and contract violently, and large-diameter thin-walled pipe fittings have very low structural stiffness and cannot resist thermal stress, which can easily cause defects such as excessive ovality, weld depression, radial contraction and overall warping. For example, in the aerospace field, excessive ovality of titanium alloy fuel pipes after welding can directly lead to assembly failure; in the petrochemical field, deformation of stainless steel oil and gas pipes can reduce the pressure-bearing capacity and increase the risk of leakage; and in the municipal water supply and drainage field, deformation of the pipe can cause interface leakage and affect engineering quality.

[0007] Further, a plurality of driving grooves are formed through the outer wall of the driving plate, butt joint bolts two are arranged on the outer wall of the pushing block corresponding to the positions of the driving grooves, one end of the butt joint bolt two extends into the driving groove and is slidably connected therewith, and a spring one is arranged on the top of the pushing block.

[0008] Further, a mounting groove three is formed in the support head, a butt joint block is slidably connected to the top of the inner side of the mounting groove three, the top end of the butt joint block extends to the outside of the support head, a magnetic piece is arranged on the bottom of the butt joint block, a spring two is arranged on the bottom of the magnetic piece, a flap is hinged to the position below the butt joint block inside the mounting groove three, a butt joint head is arranged on the top of one end of the flap outside the mounting groove three, and a rubber block is arranged on the top of the butt joint head.

[0009] Further, a limiting block is arranged on the outer wall of the mounting cavity two close to the driving plate, a limiting groove two is formed through the outer wall of the driving plate corresponding to the position of the limiting block, one end of the limiting block extends into the limiting groove two and is slidably connected therewith, a mounting opening is formed on the outer part of the mounting frame close to the driving plate, a driving motor two is arranged inside the mounting opening, and the output end of the driving motor two is fixedly connected with the mounting frame and the driving plate.

[0010] Further, a mounting cavity one is formed in the butt joint cylinder, a plurality of butt joint grooves are formed through the inner side of the mounting cavity two close to the mounting cavity one, a butt joint bolt one is arranged on the bottom end of the rod body corresponding to the position of the butt joint groove, one end of the butt joint bolt one extends into the mounting cavity one through the butt joint groove, and a top block is arranged on the top of the mounting cavity one close to the butt joint bolt one.

[0011] Further, a fixed plate is fixedly installed in the mounting cavity one inside the mounting frame close to the mounting frame, a driving motor one is arranged on the side of the fixed plate away from the mounting frame, and the output end of the driving motor one is fixedly connected with the mounting frame through the fixed plate.

[0012] The present invention is further configured such that a limiting groove is formed at one end of the docking cylinder near the mounting frame, and a mounting cylinder is provided on the outer wall of the mounting frame at a position corresponding to the limiting groove, with one end of the mounting cylinder extending into the limiting groove and rotatably connected thereto.

[0013] The beneficial effects of the laser processing anti-deformation device for thin-walled hardware parts of the present invention are as follows:

[0014] 1. Achieving precise centering and tight connection between two pipe fittings lays the foundation for high-quality welding. This equipment, through the coordinated operation of the push rod assembly, drive plate, docking block, flip plate, and butt joint, works as follows: When the drive motor rotates the drive plate, the drive plate pushes the push block and rod body radially through the drive groove, causing the support head to approach the inner wall of the pipe fitting; the docking block first contacts the inner wall of the pipe fitting and then moves downward under pressure, thereby pushing the flip plate to flip, causing the inclined butt joint to generate lateral thrust against the inner walls of the two pipe fittings through rubber blocks. This multi-component linkage structure ensures the coaxiality of the two pipe fittings through multi-point support of the support head, avoiding welding misalignment caused by initial alignment deviations; on the other hand, it forces the welding ends of the two pipe fittings to fit tightly, effectively reducing the welding gap and significantly improving the sealing performance and connection strength of the weld.

[0015] 2. Dynamic avoidance and real-time reset support work in tandem, balancing welding smoothness and deformation prevention. Through the coordinated action of bolt 1, top block, and spring 1, during the welding process where the positioning unit is rotated by the drive motor 1, as the top rod assembly approaches the welding area, bolt 1 contacts the top block and moves downwards along the arc surface, causing the rod and support head to separate from the inner wall of the pipe. This achieves precise avoidance in the welding area, preventing the support components from blocking the laser beam or being burned by high temperatures. After the top rod assembly leaves the welding area, spring 1 releases its elastic potential energy to push the rod back to its original position, and the support head re-fits the inner wall of the pipe to restore support. This coordinated design ensures no support interference in the welding area, guaranteeing a smooth welding process. At the same time, the non-welding areas maintain stable multi-point support, effectively offsetting the thermal stress generated by laser welding, suppressing deformation defects such as excessive ovality of the pipe, weld depressions, and radial shrinkage, and improving the dimensional accuracy and form and position tolerance pass rate of the welded pipe.

[0016] 3. The flexible support design protects the pipe surface, suitable for the processing needs of thin-walled pipes. The spring in the push rod assembly acts as a buffer as the drive plate pushes the rod towards the inner wall of the pipe, preventing damage to the inner wall of the thin-walled pipe due to excessive speed or impact. Simultaneously, the rubber block at the top of the joint directly contacts the inner wall of the pipe, avoiding scratches caused by hard contact and effectively protecting the surface quality of the pipe. This flexible contact and buffering linkage structure is suitable for the low stiffness and susceptibility to damage of large-diameter thin-walled pipes, expanding the applicability of the equipment.

[0030] Please see Figure 1 - Figure 7A laser processing anti-deformation device for thin-walled hardware parts includes a main body 1. A mounting rod 11 is provided on the top of the main body 1. A mounting groove 12 is provided on the outer wall of the mounting rod 11 near the top. A lifting arm 13 is slidably connected inside the mounting groove 12. A laser welding head 14 is provided at the bottom of the end of the lifting arm 13 away from the mounting rod 11. A pushing component 15 is provided on the top of the mounting rod 11. The output end of the bottom of the pushing component 15 is connected to the lifting arm 13.

[0031] A support mechanism 2 is provided at the top of the main body 1 near the mounting rod 11. The support mechanism 2 includes a docking cylinder 21 fixedly connected to the main body 1. A positioning unit 22 is provided at one end of the docking cylinder 21. The positioning unit 22 includes a mounting frame 221 rotatably connected to the docking cylinder 21. A second mounting cavity 2212 is opened inside the mounting frame 2212. A drive plate 223 is rotatably connected to the side of the second mounting cavity 2212 away from the docking cylinder 21. Several limiting holes 2214 are opened through the outer circumference of the mounting frame 221 at the position corresponding to the second mounting cavity 2212. A sliding connection is provided inside the limiting holes 2214. The push rod assembly 222 includes a rod body 2221 that is slidably connected to the inner wall of the limiting port 2214. The rod body 2221 has a second mounting groove 22211 inside. A push block 2222 is slidably connected inside the second mounting groove 22211. A support head 2223 is fixedly installed at the top of the rod body 2221. A limiting groove 211 is opened at one end of the connecting cylinder 21 near the mounting frame 221. An mounting cylinder 2215 is provided on the outer wall of the mounting frame 221 at the position corresponding to the limiting groove 211. One end of the mounting cylinder 2215 extends into the limiting groove 211 and is rotatably connected to it.

[0032] By adopting the above technical solution, the rigid sliding fit between the mounting groove 12 of the mounting rod 11 and the lifting arm 13 ensures the high stability of the laser welding head 14 during the welding process of thin-walled parts, avoiding welding defects caused by vibration. The rotating pair formed by the limiting groove 211 of the docking cylinder 21 and the mounting cylinder 2215 enables the positioning unit 22 to bear the centrifugal force of the push rod assembly 222 while maintaining rotational accuracy, which is suitable for high-speed circumferential seam welding scenarios. The rod body 2221 of the push rod assembly 222 and the push block 2222 form an elastic reset system through the spring 22221, which automatically retracts when the welding point passes through, and the non-welding area immediately restores support, dynamically balancing the contradiction between thermal deformation and welding interference.

[0033] The outer wall of the drive plate 223 is provided with several drive slots 2232. The outer wall of the push block 2222 is provided with a connecting bolt 22222 at the position corresponding to the drive slot 2232. One end of the connecting bolt 22222 extends into the drive slot 2232 and is slidably connected to it. A spring 22221 is provided on the top of the push block 2222. The support head 2223 has an installation groove 22231 inside. A docking block 2224 is slidably connected to the top of the inner side of the installation groove 22231. The top of the docking block 2224 extends to the outside of the support head 2223. A magnetic component 22241 is provided at the bottom of the docking block 22241. A spring 2226 is provided at the bottom of the magnetic component 22241. A flap 2225 is hinged inside the installation groove 22231 below the docking block 2224. A connector 22251 is provided at the top of the end of the flap 2225 outside the installation groove 22231. A rubber block 22252 is provided at the top of the connector 22251.

[0034] By adopting the above technical solution, the drive plate 223 cooperates with the inclined surface of the second docking bolt 22222 through the drive groove 2232, which converts the circumferential motion into the precise axial displacement of the push block 2222; the spring 22221 has the functions of resetting and adjusting the contact force of the support head 2223, so as to avoid damage to the thin-walled parts; the rubber block 22252 cooperates with the flip plate 2225 to eliminate gaps and prevent indentation; the floating stroke of the docking block 2224 can adapt to the ellipticity error of the large-diameter thin-walled tube.

[0035] A limiting block 2216 is provided on the outer wall of the mounting cavity 2212 near the drive plate 223. A limiting groove 2231 is provided on the outer wall of the drive plate 223 corresponding to the position of the limiting block 2216. One end of the limiting block 2216 extends into the limiting groove 2231 and is slidably connected to it. An installation port 2211 is provided on the outside of the mounting bracket 221 near the drive plate 223. A drive motor 2233 is provided inside the installation port 2211. The output end of the drive motor 2233 is fixedly connected to the mounting bracket 221 and the drive plate 223. The docking cylinder 21 has an installation cavity 212 inside. Several docking slots 2213 are formed through the side of the installation cavity 2212 near the installation cavity 212. A docking bolt 22212 is provided at the bottom of the rod 2221 corresponding to the docking slot 2213. One end of the docking bolt 22212 extends into the installation cavity 212 through the docking slot 2213. A top block 215 is provided at the top of the installation cavity 212 near the docking bolt 22212. A fixing plate 213 is fixedly installed inside the installation cavity 212 near the mounting frame 221. A drive motor 214 is provided on the side of the fixing plate 213 away from the mounting frame 221. The output end of the drive motor 214 passes through the fixing plate 213 and is fixedly connected to the mounting frame 221.

[0036] By adopting the above technical solution, the limiting block 2216 and the limiting groove 2231 form a closed-loop trajectory, limiting the rotation angle of the drive plate 223; the drive motor 214 is fixed by the fixing plate 213, and the rigid connection mounting bracket 221 realizes the overall rotation of the positioning unit 22; the docking bolt 22212 is linked across the cavity, and the arc-shaped working surface of the top block 215 has sufficient contact pressure and timely pressing response; the docking groove 2213 and the docking bolt 22212 are in clearance fit, which ensures smooth sliding and avoids the accumulation of positioning errors; the energy storage and release of the spring 22221 is synchronized with the speed of the drive motor 214, ensuring the safe avoidance distance of the support head 2223.

[0037] Working principle and usage process of this invention:

[0038] A large-diameter, thin-walled metal pipe to be welded is fitted onto the support mechanism 2, and its position is adjusted so that its welding end is aligned with the center of the support head 2223. Then, the position of another metal pipe to be welded is adjusted using an external positioning mechanism, so that its welding end is also aligned with the center of the support head 2223. During this process, the center positioning design of the support mechanism 2 ensures the coaxiality of the two pipes, effectively avoiding welding misalignment caused by initial alignment deviations, and laying the foundation for subsequent welding accuracy.

[0039] After the pipe fittings are aligned, drive motor 2233 is started. The output shaft of drive motor 2233 drives drive plate 223 to rotate counterclockwise. When drive plate 223 rotates, the drive groove 2232 on its outer wall will generate a thrust on the mating bolt 22222 on push block 2222, thereby pushing push block 2222 to move towards the top of mounting groove 22211. Since rod 2221 is not constrained by other components at this time, as mating bolt 22222 moves upward, it will drive rod 2221 to move upward synchronously through spring 1. During the upward movement of rod 2221, mating bolt 1 22212 at its bottom and mating groove 2213 on mounting cavity 2212 cooperate with each other to effectively limit the movement trajectory of rod 2221, ensuring that rod 2221 always moves smoothly in the radial direction, avoiding skew and deviation, thereby improving the stability of support. At the same time, the spring 22221 can play a buffering role, preventing the rod 2221 from moving too fast or the impact force from being too large, which could damage the inner wall of the thin-walled tube.

[0040] As the rod 2221 moves upward, it will cause the support head 2223 to move towards the inner wall of the metal pipe. During this process, the mating block 2224 will first contact and connect with the inner wall of the pipe. When the mating block 2224 is blocked by the inner wall of the pipe, the continuous movement of the support head 2223 will squeeze the mating block 2224 into the interior of the mounting groove 3 22231. During this squeezing process, the end of the flap 2225 will be pressed down, thereby causing the end of the flap 2225 located outside the mounting groove 3 22231 to flip. The flipped flap 2225 will cause the connector 22251 to move closer to the inner wall of the pipe. Because the connector 22251 adopts an inclined design, as it approaches the inner wall of the pipe fitting, the rubber block 22252 at the top exerts a lateral thrust on the inner walls of the two pipe fittings, making the welded ends of the two pipe fittings fit more tightly, effectively reducing the welding gap and improving the sealing performance and strength of the weld. At the same time, the rubber block 22252 can prevent the connector 22251 from directly contacting the inner wall of the pipe fitting and causing scratches, thus protecting the surface quality of the pipe fitting. During the process of pushing the pipe fittings together, the top of the support head 2223 will also fit tightly against the inner wall of the pipe fitting, forming a comprehensive multi-point support structure. This can effectively distribute the stress on the inner wall of the pipe fitting, avoid pipe fitting deformation caused by local stress concentration, and provide a stable support foundation for the welding process.

[0041] After the support is completed, the push assembly 15 drives the lifting arm 13 to move downward along the mounting groove 12. The lifting arm 13 drives the laser welding head 14 to approach the top of the welding end of the pipe fitting. After adjusting to the appropriate welding position, laser welding is started. During the welding process, the drive motor 214 is started. The output shaft of the drive motor 214 drives the mounting frame 221 and the entire positioning unit 22 to rotate synchronously, thereby driving the metal pipe fitting sleeved on the support mechanism 2 to rotate, realizing all-round circumferential welding of the welding end of the pipe fitting. During the rotation of the positioning unit 22, whenever a set of push rod assemblies 222 is about to approach the welding area below the laser welding head 14, the docking bolt 22212 of the set of push rod assemblies 222 will first contact and dock with the top block 215 in the mounting cavity 212. As the positioning unit 22 continues to rotate, the connecting bolt 22212 gradually moves downwards along the arc surface of the top block 215. During this downward movement, the rod 2221 moves downwards synchronously, thereby causing the support head 2223 and its connected components to separate from the inner wall of the pipe. This prevents the support head 2223 and related components from directly contacting the welding point, thus preventing the high-temperature welding area from burning the support components and avoiding the support components blocking the laser beam, which would affect the welding effect. During this process, the position of the pushing block 2222 remains unchanged, and the downward movement of the rod 2221 compresses the spring 22221, causing the spring 22221 to store elastic potential energy.

[0042] When one set of push rod assemblies 222 rotates past the welding point area with the positioning unit 22, the connecting bolt 22212 separates from the top block 215 and is no longer subjected to the pressure of the top block 215. At this time, the compressed spring 22221 releases its elastic potential energy, pushing the rod 2221 and the connected support head 2223 and other components to move upward again, re-fitting against the inner wall of the pipe and restoring the support state. This dynamic avoidance and reset support design can achieve support-free interference in the welding area, ensuring smooth welding, while continuously providing stable support in the non-welding area, effectively suppressing pipe deformation caused by thermal expansion and contraction during welding, and improving the dimensional accuracy and form and position tolerance pass rate of the welded pipe. After the entire circumferential weld is completed, all drive assemblies and laser welding head 14 are turned off, and drive motor 2233 rotates in the opposite direction to reset the push rod assembly 222, allowing the welded pipe to be removed.

[0043] In summary, compared with the prior art, the embodiments of the present invention have the following advantages:

[0044] Advantage 1: Through the linkage of components such as drive motor 2233, drive plate 223, and push rod assembly 222, drive plate 223 drives rod body 2221 and support head 2223 to approach the inner wall of the pipe fitting. The mating block 2224 is pressed and pushes the flip plate 2225 to flip, so that the butt joint 22251 is pushed by rubber block 22252 to make the two pipe fittings fit tightly together. This ensures the coaxiality of the two pipe fittings, avoids welding misalignment, reduces the welding gap, and improves the weld sealing performance.

[0045] Advantage 2: With the coordinated action of drive motor 214, docking bolt 22212, top block 215, and spring 22221, when the push rod assembly 222 approaches the welding area, the docking bolt 22212 moves down along the top block 215, causing the support head 2223 to avoid it; after it moves away, the spring 22221 pushes the reset support. This avoids the support blocking the laser or being burned, and also continuously counteracts thermal stress, suppressing pipe deformation.

[0046] Advantage 3: The spring 22221 of the push rod assembly 222 provides cushioning to prevent rigid impact damage to the pipe fitting; the rubber block 22252 of the connector 22251 achieves soft contact to prevent scratches. This is suitable for the low stiffness characteristics of large-diameter, thin-walled pipe fittings, expanding the application range and ensuring surface quality.

[0047] Fourthly, the mounting bracket 221's limiting block 2216, the rod body 2221's connecting bolt 22212, the connecting cylinder 21's limiting groove 211, and other components work together to restrict the movement trajectory and angle of each component, preventing deviation and overtravel. This reduces the probability of failure, extends equipment life, and ensures continuous processing.

[0048] Advantage 5: Drive motor 1 (214), drive motor 2 (2233), and push assembly 15 work together to achieve automated support, welding, avoidance, and resetting; adjusting the rotation angle of drive plate 223 allows for fitting different diameter pipe fittings, and resetting and removing the fitting after welding can be achieved by reversing the rotation. This improves efficiency, optimizes the operation process, and is suitable for industrial applications.

[0049] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of the present invention.
