[0002] High-strength precision stainless steel strips are used to manufacture products in various fields, including electronics, aerospace, medical, and machinery. High-strength precision stainless steel strip welding technology, with its high precision, low deformation, and high reliability, is widely used in fields with extremely high requirements for material properties, dimensional accuracy, and appearance quality, commonly found in electronics, aerospace, and precision instruments. One application is welding high-strength precision stainless steel strips into cylindrical thin-walled parts. Some components of aero-engines, such as the shrouds of compressor blades and the linings of combustion chambers, utilize these cylindrical thin-walled parts.

[0003] Existing stainless steel strip welding equipment still has shortcomings in terms of working efficiency and dimensional accuracy of welded parts, and needs further improvement and optimization. Summary of the Invention

[0004] The purpose of this invention is to provide a high-strength precision stainless steel strip welding equipment and welding method, which can achieve more accurate welding of stainless steel strips.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A high-strength precision stainless steel strip welding equipment includes a main support structure, a welding clamping mechanism and a welding machine execution mechanism disposed on the main support structure;

[0007] The main support structure includes a main support base plate placed on the ground, and a clamping support body and a welding machine execution support frame are fixed on the top of the main support base plate;

[0008] The clamping support has an inner ring rotating groove and an outer ring rotating groove arranged horizontally and coaxially on its side.

[0009] The welding clamping mechanism includes a welding clamping support inner ring rotatably connected in the inner ring rotating groove and a welding clamping support outer ring rotatably connected in the outer ring rotating groove;

[0010] A radial support beam is fixed on the inner ring and outer ring of the welding clamping support. The radial support beam is connected to a welding clamping support shaft through a radial adjustment mechanism. A welding clamping rotating ring is rotatably connected to the welding clamping support shaft and is coaxial with it. The welding clamping rotating ring is connected to a thin strip holder through a clamping drive mechanism. The thin strip holder consists of two thin strip clamping plates arranged in parallel to each other.

[0011] The welding machine actuator includes a welding machine actuator support beam that is fixed on the welding machine actuator support frame and extends horizontally.

[0012] Preferably, the radial adjustment mechanism includes a radial adjustment support slide rail fixed on the radial support beam and arranged parallel thereto, a radial adjustment support slider slidably connected on the radial adjustment support slide rail, and a welded clamping support shaft fixed on the radial adjustment support slider.

[0013] Description: The radial adjustment support slider is driven by a servo motor fixed on the radial support beam to move along the radial adjustment support slide rail via gear and rack transmission. The radial adjustment support slider drives the welding clamping support shaft, the welding clamping rotating ring and the thin strip holder to move together along the radial adjustment support slide rail, which can adjust the distance between the two thin strip holders.

[0014] Preferably, the clamping drive mechanism includes a clamping drive support slide rail fixed to one end of the welding clamping rotating ring away from the clamping support body and arranged in the radial direction of the welding clamping rotating ring. Two clamping drive support sliders are slidably connected on the clamping drive support slide rail, and two pairs of thin strip clamping plates are respectively fixed on the two clamping drive support sliders.

[0015] Explanation: The clamping drive support slider is driven by a linear motor structure of existing technology to move along the clamping drive support slide rail. The clamping drive support slider can then drive the two thin strip clamping plates to move away from each other or closer to each other. When the two thin strip clamping plates are in a state of moving away from each other, the thin strip clamp is set to a detached state. When the two thin strip clamping plates are in a state of close contact, the thin strip clamp is set to a clamping state.

[0016] Preferably, the clamping drive mechanism is connected to the welding clamping rotating ring through an axial fine-tuning mechanism. The axial fine-tuning mechanism includes two axial fine-tuning connection holes disposed on the end face of the welding clamping rotating ring. The axis of the axial fine-tuning connection holes is arranged parallel to the axis of the welding clamping rotating ring. An axial fine-tuning sliding cylinder with an inward opening is slidably connected in the axial fine-tuning connection holes. The outer end of the axial fine-tuning sliding cylinder is connected to the clamping drive support slide rail through a fine-tuning constraint ball hinge.

[0017] An axial fine-tuning drive rod is provided inside the axial fine-tuning connection hole for driving the axial fine-tuning sliding cylinder to move.

[0018] Note: The axial fine-tuning mechanism can adjust the distance and stagger of the two ends of the stainless steel strip held on the strip holder, so that the seam of the stainless steel strip can be correctly aligned after it is rolled into a cylindrical thin-walled part.

[0019] Preferably, the laser welding head assembly is connected to the welding machine execution support slider via a welding lifting mechanism. The welding lifting mechanism includes a welding lifting fixed cylinder shell fixed at the lower end of the welding machine execution support slider with its opening facing downward. A welding lifting sliding cylinder shell with its opening facing upward is slidably connected in the vertical direction inside the welding lifting fixed cylinder shell. The laser welding head assembly is fixed downward at the lower end of the welding lifting sliding cylinder shell.

[0020] The welding lifting fixed cylinder shell is equipped with a welding lifting drive rod for driving the welding lifting sliding cylinder shell to move up and down.

[0021] Explanation: The welding lifting mechanism can drive the laser welding head assembly to move up and down, adjusting the distance between the welding head of the laser welding head assembly and the cylindrical thin-walled part to be welded, so that the laser welding head assembly maintains a stable distance from the weld seam during the welding process.

[0022] Preferably, the main support structure is provided with a welding component constraint mechanism, which includes a constraint mechanism support body fixed to the side of the welding machine execution support frame, and a horizontally arranged constraint connecting shaft on the side of the constraint mechanism support body, with a welding component constraint column threadedly connected to the constraint connecting shaft.

[0023] The upper side of the welded component constraining column has a clamping plate extension groove that extends parallel to its axial direction.

[0024] The constraint connecting shaft is connected to the constraint mechanism support body through a horizontal telescopic mechanism. The horizontal telescopic mechanism includes a horizontal telescopic connecting hole that is provided on the side of the constraint mechanism support body and extends horizontally. A horizontal telescopic support cylinder with an inward opening is slidably connected in the horizontal telescopic connecting hole. The constraint connecting shaft is fixed to the outer end of the horizontal telescopic support cylinder.

[0025] The horizontal telescopic connection hole is equipped with a horizontal telescopic drive rod for driving the horizontal telescopic support cylinder to move.

[0026] Explanation: The welding component constraint mechanism supports the inner side of the cylindrical thin-walled part, while the welding component clamping mechanism clamps and constrains the cylindrical thin-walled part to the outer side of the welding component constraint column.

[0027] Preferably, the horizontal telescopic support cylinder is provided with a welding component clamping mechanism. The welding component clamping mechanism includes a welding component clamping support column fixed on the outside of the horizontal telescopic support cylinder near the constraint connection shaft. The welding component clamping support column extends radially along the horizontal telescopic support cylinder. A welding component clamping support seat is fixed at the end of the welding component clamping support column away from the horizontal telescopic support cylinder. A welding component clamping support shaft is fixed on the welding component clamping support seat. A welding component clamping deflection ring is rotatably connected to the welding component clamping support shaft.

[0028] The welding part clamping deflection ring is connected to the welding part clamping constraint plate via a clamping deflection rocker arm. One end of the clamping deflection rocker arm is fixedly connected to the welding part clamping deflection ring, and the other end of the clamping deflection rocker arm is connected to the welding part clamping constraint plate in the form of a fixed hinge.

[0029] Explanation: The welded component constraint column provides support and constraint to the inner side of the cylindrical thin-walled part. At the same time, the welded component clamping mechanism clamps and constrains the cylindrical thin-walled part to the outer side of the welded component constraint column to maintain the stability of the cylindrical thin-walled part.

[0030] Preferably, the main support structure is provided with a welding component feeding mechanism, which includes a feeding lifting support cylinder fixed to the top of the main support base plate with its opening facing upward, a feeding lifting sliding cylinder with its opening facing downward slidably connected inside the feeding lifting support cylinder, and a horizontally extending feeding support beam fixed to the top of the feeding lifting sliding cylinder.

[0031] The feeding lifting support cylinder is equipped with a feeding lifting drive rod for driving the feeding lifting sliding cylinder to move up and down;

[0032] A flip support seat is fixed at the end of the feeding support beam away from the feeding lifting sliding cylinder. A flip support shaft is fixed on the flip support seat, and a flip support ring is rotatably connected to the flip support shaft.

[0033] A rotating feeding fixed cylinder extending radially is fixed to the outside of the rotating support ring. A rotating feeding sliding cylinder is slidably connected inside the rotating feeding fixed cylinder. A feeding suction cup support plate is fixed to the outer end of the rotating feeding sliding cylinder. Multiple feeding vacuum suction cups are fixed to the side of the feeding suction cup support plate away from the rotating feeding sliding cylinder.

[0034] The tilting feed fixed cylinder is equipped with a tilting feed drive rod for driving the tilting feed sliding cylinder to move;

[0035] A thin strip raw material placement box with an upward-facing opening is fixed to the top of the main support base plate.

[0036] Note: The welding component feeding mechanism facilitates the rapid transfer of stainless steel strip placed in the strip material placement box to the strip holder, which is convenient for further rolling and welding of the stainless steel strip.

[0037] Preferably, the main support structure is provided with a welding part unloading mechanism, which includes an unloading guide plate fixed to the top of the main support base plate and arranged at an inclination, and an unloading receiving box with an upward opening fixed to the top of the main support base plate and below the lower end of the unloading guide plate.

[0038] A material dropping extension plate is slidably connected to the upper side of the material dropping guide ramp, and a material dropping extension drive rod for driving the material dropping extension plate to move is fixed to the lower side of the material dropping guide ramp.

[0039] Instructions: Position the upper end of the blanking extension plate below the welded cylindrical thin-walled part, then continue to release the thin strip holder. The welded cylindrical thin-walled part will fall naturally under gravity and roll down the upper side of the blanking extension plate and the blanking guide ramp into the blanking container to be collected.

[0040] Preferably, a high-strength precision stainless steel strip welding method, based on the above-mentioned high-strength precision stainless steel strip welding equipment, includes the following steps:

[0041] S1, Thin strip material transfer:

[0042] Rectangular stainless steel strips are placed in the strip material placement box for welding and manufacturing cylindrical thin-walled parts. The stainless steel strips placed in the strip material placement box are transferred to the strip holder by the welding part feeding mechanism.

[0043] S2. Clamping and restraint of thin strip material:

[0044] Driven by the clamping drive mechanism, the stainless steel strip is clamped at both ends along its length by the pair of strip clamping plates in each strip holder.

[0045] S3. Roll stainless steel strips into cylindrical thin-walled parts:

[0046] After the stainless steel strip is clamped by the strip holder, the two strip holders are driven by the radial adjustment mechanism to move along the radial support beam and approach each other. Then, the welding clamping rotating ring is driven by the existing technology servo motor fixed on the welding clamping support shaft to rotate around the axis of the welding clamping support shaft through gear transmission, so that the two ends of the stainless steel strip are curved upward and the middle part of the stainless steel strip is concave. Then, under the coordinated drive of the two welding clamping rotating rings, the inner ring of the welding clamping support and the outer ring of the welding clamping support, the stainless steel strip is rolled into a cylindrical thin-walled part. The two sides of the stainless steel strip along the length direction will be spliced ​​together to form a cylindrical thin-walled part, and the upper side of the cylindrical thin-walled part has a seam to be welded.

[0047] S4. Welding of stainless steel strips:

[0048] The laser welding head assembly in the welding machine actuator is connected to the welding machine actuator support beam. Driven by the welding machine actuator support slider, the laser welding head assembly can move along the welding machine actuator support slide rail and move the laser head of the laser welding head assembly to the joint on the upper side of the cylindrical thin-walled part. Spot welding is performed first to initially fix the joint of the cylindrical thin-walled part together.

[0049] Next, the laser head of the laser welding head assembly is moved along the seam extension direction of the cylindrical thin-walled part to weld the entire seam together, thus forming a complete cylindrical thin-walled part.

[0050] S5. Collect and store the welded cylindrical thin-walled parts:

[0051] After the cylindrical thin-walled parts are welded, the strip holder is released and the welded cylindrical thin-walled parts roll down along the upper side of the blanking extension plate and the blanking guide ramp under the action of gravity into the blanking container box where they are collected.

[0052] Compared with the prior art, the beneficial effects of the present invention are reflected in the following aspects:

[0053] 1. The present invention has a reasonable structural design and a high degree of automation. From the transfer, clamping and curling of the thin strip raw material to welding and the storage of the welded parts, the whole process is automated through multiple drive mechanisms and transmission devices, which reduces manual intervention and improves production efficiency and product quality stability.

[0054] 2. This invention is easy to operate and produces high-quality parts. In the process of rolling stainless steel strip into cylindrical thin-walled parts, the coordinated drive of the welding clamping rotating ring, the welding clamping supporting inner ring and outer ring, and the cooperation of the welding part constraint mechanism and the welding part pressing mechanism can make the stainless steel strip roll evenly and effectively support and press the cylindrical thin-walled parts to maintain their stability, thereby improving the forming quality of the parts.

[0055] 3. The welding quality of this invention is reliable. Spot welding is first performed to initially fix the joint, and then continuous welding is performed by moving the laser welding head along the extension direction of the joint. This welding method can ensure the quality of the weld and make the welded cylindrical thin-walled parts have high strength and sealing performance.

[0056] 4. The various components of the equipment of the present invention are rationally arranged and closely cooperate with each other. The radial adjustment mechanism can flexibly adjust the spacing between the thin strip holders to adapt to the processing needs of stainless steel thin strips and cylindrical thin-walled parts of various sizes. The overall structure is compact, occupies little space, and is conducive to improving the utilization rate of the production site. Attached Figure Description

First, the inner rod of the feeding lifting drive rod 513 retracts, driving the feeding lifting sliding cylinder 512, the feeding support beam 52, the flipping feeding fixing cylinder 541, the flipping feeding sliding cylinder 542, the feeding suction cup support plate 543, and the multiple feeding vacuum suction cups 540 to move down together, so that the feeding suction cup support plate 543 extends into the strip material placement box 55. Using the adsorption effect of the multiple feeding vacuum suction cups 540, the uppermost piece of stainless steel strip is adsorbed.

[0107] Next, the inner rod of the feeding lifting drive rod 513 extends and drives the feeding lifting sliding cylinder 512, the feeding support beam 52, the flip feeding fixed cylinder 541, the flip feeding sliding cylinder 542, the feeding suction cup support plate 543, and multiple feeding vacuum suction cups 540, together with the stainless steel strip that is being sucked up, to move upward. At the same time as moving upward, the flip support ring 533 is driven by a servo motor fixed on the flip support base 531 to rotate around the axis of the flip support shaft 532 through gear transmission. This causes the flip support ring 533 to drive the flip feeding fixed cylinder 541, the flip feeding sliding cylinder 542, the feeding suction cup support plate 543, and multiple feeding vacuum suction cups 540, together with the stainless steel strip that is being sucked up, to rotate around the axis of the flip support shaft 532. Finally, after the multiple feeding vacuum suction cups 540 are in the upward position, the flip support ring 533 stops rotating.

[0108] Driven by the extension of the inner rod of the feeding lifting drive rod 513, the stainless steel strip that has been adsorbed is finally brought to the same horizontal height as the strip holder 28.

[0109] Example 5: Based on Example 3, such as Figure 3As shown, the clamping drive mechanism 27 includes a clamping drive support slide rail 271 fixed to one end of the welding clamping rotating ring 26 away from the clamping support body 12 and arranged in the radial direction of the welding clamping rotating ring 26. Two clamping drive support sliders 272 are slidably connected on the clamping drive support slide rail 271. Two pairs of thin strip clamping plates 280 are respectively fixed on the two clamping drive support sliders 272.

[0110] The clamping drive support slider 272 is driven by a linear motor structure of the prior art to move along the clamping drive support slide rail 271. The stator of the linear motor is fixed on the clamping drive support slide rail 271 and arranged along the extension direction of the clamping drive support slide rail 271. The mover of the linear motor is fixed on the clamping drive support slider 272.

[0111] A grating ruler for monitoring the relative movement position of the clamping drive support slider 272 is provided between the clamping drive support slide rail 271 and the clamping drive support slider 272. The scale grating of the grating ruler is fixed on the clamping drive support slide rail 271, and the grating reading head of the grating ruler is fixed on the clamping drive support slider 272.

[0112] Example 6: This example describes a high-strength precision stainless steel strip welding method, based on the high-strength precision stainless steel strip welding equipment of Example 5 above. The difference from Example 4 is that in step S2, the clamping drive support slider 272 is driven by a linear motor structure of the prior art to move along the clamping drive support slide rail 271. The clamping drive support slider 272 can then drive the two strip clamping plates 280 to move away from or towards each other.

[0113] When the two thin strip clamping plates 280 are in a state of being far apart from each other, the thin strip clamp 28 is set to a detached state; when the two thin strip clamping plates 280 are in a state of being close to each other, the thin strip clamp 28 is set to a clamping state.

[0114] When the stainless steel strip that has been adsorbed is at the same horizontal level as the strip holder 28, the strip holder 28 is in a detached state. The radial adjustment mechanism 24 drives the two strip holders 28 to move closer to each other, so that the two ends of the stainless steel strip along the length direction are between the two strip holding plates 280. Then the strip holder 28 is changed to a holding state, so that the stainless steel strip can be firmly held.

[0115] Example 7: Based on Example 5, such as Figure 2 As shown, the radial adjustment mechanism 24 includes a radial adjustment support slide rail 241 fixed on the radial support beam 23 and arranged parallel thereto, a radial adjustment support slider 242 slidably connected on the radial adjustment support slide rail 241, and a welding clamping support shaft 25 fixed on the radial adjustment support slider 242.

[0116] The radial adjustment support slider 242 is driven by a prior art servo motor fixed on the radial support beam 23 to move along the radial adjustment support slide rail 241 via gear and rack drive;

[0117] A grating ruler for monitoring the relative movement position of the radial adjustment support slider 242 is provided between the radial adjustment support slider 242 and the radial adjustment support slide rail 241. The scale grating of the grating ruler is fixed on the radial adjustment support slide rail 241, and the grating reading head of the grating ruler is fixed on the radial adjustment support slider 242.

[0118] like Figure 3 As shown, the clamping drive mechanism 27 is connected to the welding clamping rotating ring 26 through the axial fine adjustment mechanism 29. The axial fine adjustment mechanism 29 includes two axial fine adjustment connecting holes 290 provided on the end face of the welding clamping rotating ring 26. The axis of the axial fine adjustment connecting holes 290 is arranged parallel to the axis of the welding clamping rotating ring 26. An axial fine adjustment sliding cylinder 291 with an inward opening is slidably connected in the axial fine adjustment connecting holes 290. The outer end of the axial fine adjustment sliding cylinder 291 is connected to the clamping drive support slide rail 271 through a fine adjustment constraint ball hinge 292.

[0119] An axial fine-tuning drive rod 293 is provided inside the axial fine-tuning connection hole 290 for driving the axial fine-tuning sliding cylinder 291 to move. The axial fine-tuning drive rod 293 is an existing electrically controlled telescopic rod driven by a servo motor. The outer end of the axial fine-tuning drive rod 293 is fixedly connected to the inner end of the axial fine-tuning connection hole 290, and the inner end of the axial fine-tuning drive rod 293 is fixedly connected to the inner end of the axial fine-tuning sliding cylinder 291.

[0120] An optical grating ruler for monitoring the relative movement position of the axial fine-tuning slide cylinder 291 is provided between the axial fine-tuning slide cylinder 291 and the axial fine-tuning connection hole 290. The scale grating of the optical grating ruler is fixed on the axial fine-tuning connection hole 290, and the grating reading head of the optical grating ruler is fixed on the axial fine-tuning slide cylinder 291.

[0121] Example 8: This example describes a high-strength precision stainless steel strip welding method, based on the high-strength precision stainless steel strip welding equipment of Example 7 above. The difference from Example 6 is that in step S3, the radial adjustment support slider 242 is driven by a prior art servo motor fixed on the radial support beam 23 through gear and rack drive to move along the radial adjustment support slide rail 241. The radial adjustment support slider 242 drives the welding clamping support shaft 25, the welding clamping rotating ring 26 and the strip holder 28 to move together along the radial adjustment support slide rail 241, which can adjust the distance between the two strip holders 28.

[0122] Meanwhile, the welding clamping support inner ring 21 is driven by a prior art servo motor fixed on the clamping support body 12 to rotate around the horizontal axis of the inner ring rotating groove 121 via gear ring transmission, and the welding clamping support outer ring 22 is driven by a prior art servo motor fixed on the clamping support body 12 to rotate around the horizontal axis of the outer ring rotating groove 122 via gear ring transmission. The rotation directions of the welding clamping support inner ring 21 and the welding clamping support outer ring 22 are opposite, which further causes the two ends of the stainless steel strip to bend upwards and the middle part of the stainless steel strip to be concave.

[0123] Under the coordinated drive of the two welding clamping rotating rings 26, the welding clamping support inner ring 21, and the welding clamping support outer ring 22, the stainless steel strip is rolled into a cylindrical thin-walled part. The two sides of the stainless steel strip along the length direction are spliced ​​together to form a cylindrical thin-walled part, and the upper side of the cylindrical thin-walled part has a seam to be welded.

[0124] Example 9: Based on Example 7, as follows Figure 1 As shown, the main support structure 10 is provided with a welding component constraint mechanism 40. The welding component constraint mechanism 40 includes a constraint mechanism support body 41 fixed on the side of the welding machine execution support frame 13. A horizontally arranged constraint connecting shaft 411 is provided on the side of the constraint mechanism support body 411. A welding component constraint column 42 is threadedly connected to the constraint connecting shaft 411.

[0125] The upper side of the welded component constraint column 42 has a clamping plate extension groove 421 extending parallel to its axial direction;

[0126] The constraint connecting shaft 411 is connected to the constraint mechanism support body 41 through the horizontal telescopic mechanism 43. The horizontal telescopic mechanism 43 includes a horizontal telescopic connecting hole 430 that is provided on the side of the constraint mechanism support body 41 and extends horizontally. A horizontal telescopic support cylinder 431 with an inward opening is slidably connected in the horizontal telescopic connecting hole 430. The constraint connecting shaft 411 is fixed to the outer end of the horizontal telescopic support cylinder 431.

[0127] The horizontal telescopic connection hole 430 is provided with a horizontal telescopic drive rod 432 for driving the horizontal telescopic support cylinder 431 to move. The horizontal telescopic drive rod 432 is an existing electric control telescopic rod driven by a servo motor. The outer end of the horizontal telescopic drive rod 432 is fixedly connected to the inner end of the horizontal telescopic connection hole 430, and the inner end of the horizontal telescopic drive rod 432 is fixedly connected to the horizontal telescopic support cylinder 431.

[0128] A grating ruler for monitoring the relative movement position of the horizontal telescopic support cylinder 431 is provided between the horizontal telescopic support cylinder 431 and the horizontal telescopic connection hole 430. The scale grating of the grating ruler is fixed on the horizontal telescopic connection hole 430, and the grating reading head of the grating ruler is fixed on the horizontal telescopic support cylinder 431.

[0129] like Figure 1 As shown, the horizontal telescopic support cylinder 431 is equipped with a welded component clamping mechanism 44, such as... Figure 6 , Figure 7 As shown, the welding component clamping mechanism 44 includes a welding component clamping support column 441 fixed on the outside of the horizontal telescopic support cylinder 431 near the constraint connection shaft 411. The welding component clamping support column 441 extends radially along the horizontal telescopic support cylinder 431. A welding component clamping support seat 442 is fixed at one end of the welding component clamping support column 441 away from the horizontal telescopic support cylinder 431. A welding component clamping support shaft 443 is fixed on the welding component clamping support seat 442. The axial direction of the welding component clamping support shaft 443 is perpendicular to both the axial direction of the horizontal telescopic support cylinder 431 and the axial direction of the welding component clamping support column 441. A welding component clamping deflection ring 444 is rotatably connected to the welding component clamping support shaft 443.

[0130] The welding part clamping deflection ring 444 is driven by a prior art servo motor fixed on the welding part clamping support 442 to rotate around the axis of the welding part clamping support shaft 443 via gear transmission;

[0131] The welding part clamping deflection ring 444 is connected to the welding part clamping constraint plate 446 via a clamping deflection rocker arm 445. One end of the clamping deflection rocker arm 445 is fixedly connected to the welding part clamping deflection ring 444, and the other end of the clamping deflection rocker arm 445 is connected to the welding part clamping constraint plate 446 in the form of a fixed hinge.

[0132] Example 10: This example describes a high-strength precision stainless steel strip welding method, based on the high-strength precision stainless steel strip welding equipment of Example 9 above. The difference from Example 8 is that, in step S3, when the stainless steel strip is rolled into a cylindrical thin-walled part, the welding part constraint mechanism 40 supports the inner side of the cylindrical thin-walled part, and the welding part pressing mechanism 44 presses and constrains the cylindrical thin-walled part to the outer side of the welding part constraint column 42.

[0133] The inner rod of the horizontal telescopic drive rod 432 extends out, driving the horizontal telescopic support cylinder 431, the constraint connecting shaft 411, and the welded constraint column 42 together to move along the axial direction of the horizontal telescopic connecting hole 430, and causing the welded constraint column 42 to move towards the cylindrical thin-walled part, so that the entire welded constraint column 42 extends into the inner side of the cylindrical thin-walled part. At this time, the thin strip holder 28 is in the clamping plate extension groove 421.

[0134] Next, the welding part clamping deflection ring 444 is driven by a prior art servo motor fixed on the welding part clamping support 442 to rotate around the axis of the welding part clamping support shaft 443 through gear transmission. The welding part clamping deflection ring 444 drives the welding part clamping constraint plate 446 to deflect towards the cylindrical thin-walled part through the clamping deflection rocker arm 445 until the welding part clamping constraint plate 446 presses and constrains the outer surface of the cylindrical thin-walled part.

[0135] At this time, the welded component constraint column 42 provides support and constraint to the inner side of the cylindrical thin-walled part, and the multiple welded component pressing constraint plates 446 provide pressing and fixing constraint to the outer side of the cylindrical thin-walled part, firmly constraining the cylindrical thin-walled part to the welded component constraint column 42 to maintain the stability of the cylindrical thin-walled part.

[0136] In step S5, after the cylindrical thin-walled part is welded, the thin strip holder 28 first changes to a loose state.

[0137] The retraction of the inner rod of the horizontal telescopic drive rod 432 causes the horizontal telescopic support cylinder 431, the constraint connecting shaft 411, the welded component constraint column 42, and the completed welded cylindrical thin-walled part to move together along the axial direction of the horizontal telescopic connecting hole 430, and causes the completed welded cylindrical thin-walled part to move away from the thin strip holder 28. When the thin strip holder 28 overlaps the cylindrical thin-walled part by 20% of the length of the cylindrical thin-walled part in the axial direction, the welded component clamping deflection ring 444 is fixed to the welded component clamping support. The existing servo motor on the support 442 is driven by gear transmission to rotate around the axis of the welding part clamping support shaft 443. The welding part clamping deflection ring 444 drives the welding part clamping constraint plate 446 to deflect away from the cylindrical thin-walled part through the clamping deflection rocker arm 445, so that the welding part clamping constraint plate 446 is released from the clamping constraint on the outer side of the cylindrical thin-walled part. At the same time, the thin strip holder 28 changes to the clamping state, and the thin strip holder 28 is used to clamp the completed cylindrical thin-walled part again.

[0138] The inner rod of the horizontal telescopic drive rod 432 continues to retract, driving the horizontal telescopic support cylinder 431, the constraint connecting shaft 411, and the welded component constraint column 42 to move along the axial direction of the horizontal telescopic connecting hole 430, and causing the welded component constraint column 42 to move away from the thin strip holder 28, thus pulling the welded component constraint column 42 out from the inside of the cylindrical thin-walled part that has been welded.

[0139] Finally, the inner rod of the material dropping extension drive rod 631 extends, causing the material dropping extension plate 63 to move upward along the plane of the material dropping guide ramp 61, so that the upper end of the material dropping extension plate 63 is below the completed cylindrical thin-walled part. Then, the thin strip holder 28 continues to be turned into a loose state, and the completed cylindrical thin-walled part falls naturally under the action of gravity, rolling down along the upper side of the material dropping extension plate 63 and the material dropping guide ramp 61 into the material dropping container 62 for collection.

[0140] Example 11: Based on Example 9, as follows Figure 1 As shown, the laser welding head assembly 32 is connected to the welding machine execution support slider 312 via the welding lifting mechanism 33, as follows: Figure 5 As shown, the welding lifting mechanism 33 includes a welding lifting fixed cylinder shell 331 fixed to the lower end of the welding machine execution support slider 312 and with the opening facing downward.

The laser welding head assembly 32 is fixed to the lower end of the welding lifting sliding cylinder shell 332 with the opening facing downward.

[0141] The welding lifting fixed cylinder shell 331 is provided with a welding lifting drive rod 333 for driving the welding lifting sliding cylinder shell 332 to move up and down. The welding lifting drive rod 333 is an existing electric control telescopic rod driven by a servo motor. The outer rod end of the welding lifting drive rod 333 is fixedly connected to the top of the welding lifting fixed cylinder shell 331, and the inner rod end of the welding lifting drive rod 333 is fixedly connected to the bottom of the welding lifting sliding cylinder shell 332.

[0142] A grating ruler is provided between the welding lifting sliding cylinder shell 332 and the welding lifting fixed cylinder shell 331 for monitoring the relative movement position of the welding lifting sliding cylinder shell 332. The scale grating of the grating ruler is fixed on the welding lifting fixed cylinder shell 331, and the grating reading head of the grating ruler is fixed on the welding lifting sliding cylinder shell 332.

[0143] Example 12: This example describes a high-strength precision stainless steel strip welding method, based on the high-strength precision stainless steel strip welding equipment of Example 11 above. The difference from Example 10 is that in step S4, the welding machine execution support slider 312 is driven by a prior art servo motor fixed on the welding machine execution support slider 312 through gear and rack transmission to move along the welding machine execution support slide rail 311. The welding machine execution support slider 312 drives the laser welding head assembly 32 to move together to the top of the cylindrical thin-walled part.

[0144] Next, the inner rod of the welding lifting drive rod 333 extends and drives the welding lifting sliding cylinder shell 332 together with the laser welding head assembly 32 to move down, bringing the welding head of the laser welding head assembly 32 close to and aligning with the joint of the cylindrical thin-walled part to be welded.

[0145] Finally, the welding machine execution support slider 312 is driven by a conventional servo motor fixed on the welding machine execution support slider 312 through gear and rack transmission to move along the welding machine execution support slide rail 311. That is, the welding machine execution support slider 312 drives the laser welding head assembly 32 to move together along the seam extension direction of the cylindrical thin-walled part. The laser welding head assembly 32 continuously welds the seam of the cylindrical thin-walled part together to form a complete cylindrical thin-walled part.

S4. Welding of stainless steel strips: The laser welding head assembly (32) in the welding machine actuator (30) is connected to the welding machine actuator support beam (31). The laser welding head assembly (32) can move along the welding machine actuator support slide rail (311) under the drive of the welding machine actuator support slider (312), and move the laser head of the laser welding head assembly (32) to the joint on the upper side of the cylindrical thin-walled part. Spot welding is performed first to fix the joint of the cylindrical thin-walled part together initially. Next, the laser head of the laser welding head assembly (32) is moved along the seam extension direction of the cylindrical thin-walled part to weld the entire seam together, thus forming a complete cylindrical thin-walled part. S5. Collect and store the welded cylindrical thin-walled parts: After the cylindrical thin-walled parts are welded, the thin strip holder (28) is released and the welded cylindrical thin-walled parts roll down along the upper side of the blanking extension plate (63) and blanking guide inclined plate (61) under the action of gravity into the blanking container (62) and are collected.
