[0002] In the field of metal welding, laser welding has become a core technology for joining circular metal parts due to its advantages such as high energy density, small welding deformation, and high precision. The welding quality of circular metal materials directly affects the performance and reliability of key components such as mechanical transmission and sealing structures. With the increasing demand for welding automation and high precision in the manufacturing industry, higher requirements are being placed on the stability and adaptability of laser welding equipment.

[0003] Existing laser welding equipment for ring-shaped metal materials typically requires frequent replacement of the metal material after welding the top or sides of stacked rings. Furthermore, the clamping operation of existing equipment is cumbersome during loading and unloading, requiring manual adjustment of multiple components to fix and unlock the rings, significantly reducing the equipment's continuous operation capability and resulting in low efficiency.

The annular metal material is placed on the placement plate. The tensioning component automatically tensions the material and then presses down on the placement plate, so that insertion rod one moves down in sleeve one and insertion rod two inserts into slot one to lock the placement plate. At the same time, the linkage component drives the rotating rod and the pressing component to press the material surface. During welding, rotating motor one drives the structure to rotate to adjust the welding position, rotating motor two drives the placement plate to rotate, and the laser welding gun slides on the support top frame to adjust the position. After welding is completed, rotating motor two and rotating motor one drive the pulling component to move, so that insertion rod two disengages from slot one.

When the placement plate is pressed down, the racks on both sides of the toothed plate mesh with the gears to drive the gears to rotate synchronously, which in turn drives the rotating rod to rotate. The folding rod then drives the arc-shaped clamping plate to rotate and press down around the axis of the rotating rod, gradually pressing the surface of the metal material to ensure the stability of the material during welding. After welding is completed, the placement plate moves up and resets under the action of the buffer component.

[0029] It should be noted that the terms "first," "second," etc., in the specification and claims of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence.

[0030] One preferred embodiment of this application, such as Figures 1 to 9As shown, a metal material laser welding device includes: a support base 1, and further includes: a support plate 9, a rotating motor 10, a mounting head 11, a support top frame 12, a laser welding gun 13, a rotating motor 14, a placement plate 16, a sleeve 17, an insertion rod 18, a mounting block 19, a sleeve 20, an insertion rod 21, a tensioning assembly, a rotating rod 23, a linkage assembly, a pulling assembly, and a buffer assembly; the support plate 9 is disposed between the inner walls of both sides of the support base 1; the rotating motor 10 is fixedly installed at the middle position of the outer wall of one side of the support base 1; there are two mounting heads 11, which are respectively fixedly installed on both sides of the support plate 9, with one mounting head 11 having its side away from the support plate 9 connected to the inner wall of the other side of the support base 1. The middle position is rotated and installed, and the other mounting head 11 is fixedly connected to the output shaft of the rotating motor 10 on the side away from the support plate 9; the support top frame 12 is vertically fixed between the top two sides of the support base frame 1; the laser welding gun 13 is vertically set and is slidably installed on one side of one end of the support top frame 12 through the sliding component 1; the rotating motor 14 is fixedly installed at the center position of the bottom of the support plate 9, and the output shaft of the rotating motor 14 is horizontally fixedly installed on the mounting plate 15; the placement plate 16 is horizontally set directly above the mounting plate 15; there are two sleeves 17, and the mounting plate 15 has mounting grooves on both sides of the top edge of the mounting plate 15. The two sleeves 17 are vertically fixedly installed on the bottom inner wall of the two mounting grooves 1 respectively; the insertion rod 1 There are two insert rods 18, each vertically fixed to the bottom edges of the mounting plate 16, and each insert rod 18 is inserted into a corresponding sleeve 17; there are four mounting blocks 19, two sets of mounting blocks 19 are fixedly installed to the top edges of the mounting plate 15, and the two sets of mounting blocks 19 are located on the side of the corresponding sleeve 17 away from the mounting plate 16; there are two sleeves 20, the two ends of which are slidably installed between the two sets of mounting blocks 19 via sliding components 2; each of the two sleeves 17 has an opening 1 on the top of the side away from each other, and each of the two insert rods 18 has a slot 1 on the top of the side away from each other, and insert rod 21... There are two insert rods 21, with their opposite sides inserted into two sleeves 20. The opposite sides of the insert rods 21 pass through two openings 1 and contact the corresponding insert rod 18. Buffer springs 22 are fixedly installed between the opposite sides of the insert rods 21 and the opposite inner walls of the corresponding sleeves 20. There are two sets of tensioning components, installed on both sides of the top center of the placement plate 16, to tension the annular metal material after it is placed. There are two rotating rods 23, horizontally installed between the two ends of the opposite sides of the two sets of tensioning components. Each rotating rod 23 is equipped with a pressing component to press and fix the surface of the metal material.A linkage assembly is positioned between the mounting plate 15 and the two rotating rods 23, used to move the placement plate 16 downwards, thereby driving the clamping assembly to press against the surface of the metal material. Two sets of pulling assemblies are positioned on either side of the mounting plate 15, used to pull the sleeve 20 through rotation of the mounting plate 15. A buffer assembly is installed between the top center of the mounting plate 15 and the placement plate 16 to buffer the downward movement of the placement plate 16.

[0031] The annular metal material is placed on the placement plate 16, and the clamping assembly automatically clamps the material. Pressing down on the placement plate 16 causes the insertion rod 18 to move downward within the sleeve 17. When the insertion rod 18 reaches the bottom, the insertion rod 21 passes through the opening 1 and inserts into the slot 1, locking the placement plate 16 to prevent it from shaking during welding and affecting the welding process. Simultaneously, the downward movement of the placement plate 16 drives the rotating rod 23 to rotate via the linkage assembly, thereby causing the clamping assembly to press the surface of the metal material. If welding is required on the top or side of the metal material, the rotating motor 10 is started, causing the mounting head 11, mounting plate 15, and placement plate 16 to rotate vertically, positioning the metal material in a suitable welding position. The rotating motor 24 is started, causing the mounting plate 15 and placement plate 16 to rotate. Finally, the laser welding gun 13 slides on the support frame 12 via the sliding assembly 1. The machine operates by adjusting the position of the metal material according to its dimensions and performing welding operations. After welding is completed, the second rotating motor 14 starts, driving the mounting plate 15 and the placement plate 16 to rotate, thereby driving the pulling component to rotate. After the pulling component is adjusted to the appropriate position, the first rotating motor 10 starts, driving the mounting plate 15 and the pulling component to rotate vertically. The pulling component drives the sleeve 20 to move outward, and at the same time, the sleeve 20 rotates, causing the two inserts 21 to disengage from their corresponding slots. Then, the buffer component drives the placement plate 16 to reset, driving the clamping component to reset, unlocking the clamping and fixing of the metal material. At this time, the mounting plate 15 is at a certain tilt angle, and the metal material is clamped by the supporting material. The operator can directly remove the ring-shaped metal material in a direction perpendicular to the placement plate 16, realizing convenient loading and unloading operations and improving the continuous operation capability and production efficiency of the welding equipment.

[0032] Further reference Figure 1 , Figure 3 and Figures 6-8The tensioning assembly includes: mounting block 201, insert block 202, and buffer spring 203. The two mounting blocks 201 are curved on the opposite sides. The two mounting blocks 201 are fixedly installed on the top sides of the placement plate 16. The two rotating rods 23 are rotatably installed between the two ends of the opposite sides of the two mounting blocks 201. The opposite sides of the two mounting blocks 201 are provided with slots 2. The two insert blocks 202 are inserted into the corresponding slots 2. The buffer spring 203 is fixedly installed between the insert block 202 and the mounting block 201. The edges of the opposite sides of the top of the two insert blocks 202 are smooth curved.

[0033] The annular metal material is placed on the placement plate 16. When the material falls, it presses against the smooth curved surfaces of the two inserts 202, causing the inserts 202 to move within the slot and compress the buffer spring 203. The elastic force of the buffer spring 203 provides a continuous clamping force to the inserts 202, ensuring that the metal material is firmly supported. When it is necessary to remove the material, the metal material is lifted upwards, and the buffer spring 203, which has lost pressure, returns to its original position, pushing the inserts 202 to move. This achieves the support and fixation of the metal material, while also facilitating loading and unloading.

[0034] Further reference Figure 1 , Figure 3 and Figures 6-7 The clamping assembly includes: two folding rods 301 and two arc-shaped clamping plates 302. The two folding rods 301 are respectively fixedly installed on one side of the two rotating rods 23, and the two arc-shaped clamping plates 302 are respectively fixedly installed on the ends of the two folding rods 301 away from the rotating rods 23.

[0035] When the placement plate 16 is pressed down, the linkage component drives the rotating rod 23 to rotate, and the folding rod 301, which is fixedly connected to the rotating rod 23, rotates accordingly. The folding rod 301 drives the arc-shaped clamping plate 302 at its end to rotate and press down around the axis of the rotating rod 23. As the arc-shaped clamping plate 302 rotates, it gradually presses the material surface to ensure the stability of the material position during the welding process. After the welding is completed, the placement plate 16 moves up and resets under the action of the buffer component. The linkage component drives the rotating rod 23 to rotate in the opposite direction, and the folding rod 301 drives the arc-shaped clamping plate 302 to lift up simultaneously, releasing the clamping of the metal material and facilitating subsequent unloading, thus achieving the clamping and fixing of the metal material.

[0036] Further reference Figure 6 and Figure 7The linkage component includes two gears 401 and a toothed plate 402. The two gears 401 are fixedly installed on the other side of the two rotating rods 23. A sliding opening is provided at the center of the top of the placement plate 16. The sliding opening is located between the two mounting blocks 201. The toothed plate 402 is vertically arranged. Both ends of the toothed plate 402 are provided with racks. The bottom of the toothed plate 402 is fixedly installed on the top of the mounting plate 15. The top of the toothed plate 402 passes through the sliding opening. The two sides of the toothed plate 402 are slidably arranged with the inner walls of the two sides of the sliding opening. The two gears 401 are respectively meshed with the two ends of the toothed plate 402.

[0037] When the placement plate 16 is pressed down, the racks on both sides of the toothed plate 402 mesh with the gears 401 fixed on the rotating rod 23. As the placement plate 16 moves down, the toothed plate 402 moves upward relative to the placement plate 16, driving the gears 401 on both sides to rotate synchronously. The gears 401 drive the rotating rod 23 to rotate, thereby causing the folding rod 301 and the arc-shaped pressing plate 302 to rotate and press against the surface of the metal material. After welding is completed, the placement plate 16 moves up and resets under the action of the buffer assembly. The toothed plate 402 moves downward relative to the placement plate 16, and the gears 401 rotate in the opposite direction, causing the rotating rod 23, the folding rod 301 and the arc-shaped pressing plate 302 to lift up, releasing the pressing on the metal material and realizing the pressing and fixing of the metal material.

[0038] Further reference Figure 1 and Figures 3-5 The pulling assembly includes: a first connecting rod 501, two second connecting rods 502, a third mounting block 503, and a limiting plate 504. The two first connecting rods 501 are fixedly installed on both sides of the mounting plate 15, and the two second connecting rods 502 are fixedly installed at both ends of the first connecting rod 501 away from the mounting plate 15. The two third mounting blocks 503 are fixedly installed at both ends of the top of the support base 1. One limiting plate 504 is fixedly installed at the top of one third mounting block 503 near the mounting plate 15, and the other limiting plate 504 is fixedly installed at the bottom of the other third mounting block 503 near the mounting plate 15. The end of the limiting plate 504 near the mounting plate 15 is semi-circular. One limiting plate 504 is located above the first connecting rod 501 in vertical height, and the other limiting plate 504 is located below the first connecting rod 501 in vertical height. Limiting openings are opened at the top of the limiting plates 504 that are close to each other. Rotation grooves are opened on both sides of the top of the mounting plate 15.

[0039] Initially, the mounting plate 15 remains horizontal. Since the two limiting plates 504 are located above and below the connecting rod 501 respectively, and the connecting rod 501 is offset from the limiting plate 504, the rotating motor 10 is started to rotate the support plate 9 vertically until it reaches the appropriate position. After welding is completed, the rotating motor 10 is started to reset the support plate 9 to a horizontal state. When the rotating motor 14 is started to rotate the mounting plate 15, the connecting rod 501 fixed on both sides of the mounting plate 15 rotates accordingly. The connecting rod 501 drives the connecting rods 502 at both ends to perform a circular motion around the rotation center of the mounting plate 15, aligning the connecting rod 501 with the limiting plate 504. The rotating motor 10 is started again to rotate the support plate 9, and the two connecting rods 502 gradually... Contacting one end of the limiting plate 504, the semi-circular setting of one end of the limiting plate 504 and the T-shaped setting of the two connecting rods 502 cause the limiting plate 504 to hook onto the two connecting rods 502. Then, under the blocking action of the limiting plate 504, the direction of movement is changed, thereby pulling the connecting rod 501 to move outward. At the same time, since the two limiting plates 504 are located above and below the connecting rod 501 respectively, both sleeves 20 rotate in the same direction. The connecting rod 501 is connected to the sleeve 20, thereby causing the sleeve 20 to slide outward between the mounting blocks 19, so that the insert rod 21 disengages from the slot 1 of the insert rod 18, completing the unlocking of the placement plate 16. This facilitates the unloading operation and improves the continuous operation capability and production efficiency of the welding equipment.

[0040] Further reference Figure 3 and Figure 9 The buffer assembly includes: sleeve three 601, sleeve four 602 and buffer spring three 603. A mounting groove two is provided at the center of the top of the mounting plate 15. Sleeve three 601 is fixedly installed on the inner wall of the bottom of the mounting groove two. Sleeve four 602 is set vertically. The top of sleeve four 602 is fixedly installed at the center of the bottom of the placement plate 16. The bottom of sleeve four 602 is inserted into sleeve three 601. Buffer spring three 603 is fixedly installed between the inner wall of the bottom of sleeve three 601 and the outer wall of the bottom of sleeve four 602. An opening two is provided at the bottom of sleeve four 602. Toothed plate 402 passes through opening two.

[0041] When the annular metal material is placed on the placement plate 16 and pressed down, sleeve four 602 will slide towards sleeve three 601. During this process, buffer spring three 603 is compressed, which slows down the descent speed of placement plate 16 through elastic deformation, thus playing a buffering role. In addition, toothed plate 402 passes through opening two and does not affect the sliding. After welding is completed, pull the assembly to unlock placement plate 16. Buffer spring three 603 releases elastic potential energy, pushing sleeve four 602 to drive placement plate 16 to rise and reset smoothly. Its continuous supporting force ensures that placement plate 16 rebounds slowly, avoids material shaking, and ensures stable loading and unloading of metal materials.

[0042] Further reference Figure 2 , Figure 3 and Figure 5 The first sliding component includes an electric slide rail 701 and an electric slider 702. The electric slide rail 701 is fixedly installed on one side of one end of the support top frame 12, and the electric slider 702 is slidably installed on the electric slide rail 701. The electric slider 702 is fixedly connected to one end of the laser welding gun 13. The second sliding component includes a second slide rail 703, a second slider 704, and a fourth buffer spring 705. The first mounting block 19 has a mounting groove 3 at one end near the second sleeve 20. The second slide rail 703 is fixedly installed on the inner wall of the mounting groove 3 at the end away from the second sleeve 20. The second slider 704 is slidably installed on the second slide rail 703. The second slider 704 is rotatably installed on one end of the second sleeve 20 through a torsion spring shaft. The fourth buffer spring 705 is fixedly installed between the inner wall of one side of the mounting groove 3 and the second slider 704.

[0043] During welding operations, the electric slide rail 701 is energized, driving the electric slider 702 to slide on it, thereby moving the laser welding gun 13 along the support top frame 12. According to the size of the annular metal material and the welding position requirements, the position of the laser welding gun 13 is precisely adjusted to complete the welding operation. When the pulling component moves the sleeve 20, the sleeve 20 is hooked and limited by the limiting plate 504 through the torsion spring shaft, thereby driving the sleeve 20 to rotate. The slider 2 704 slides on the slide rail 2 703, and the buffer spring 4 705 is compressed or stretched, which plays a buffering role on the sliding of the slider 2 704 and avoids the rigid impact when the sleeve 20 moves. At the same time, after the pulling component and other components are reset, the elastic force of the buffer spring 4 705 causes the slider 2 704 to drive the sleeve 20 to reset. At the same time, the torsion spring shaft drives the sleeve 20 to rotate and reset, preparing for the next insertion and locking of the insertion rod 21.

[0044] Further reference Figure 7 An elastic abutment plate 801 is fixedly installed at the bottom of the arc-shaped pressing plate 302 near the rotating rod 23. The end of the elastic abutment plate 801 away from the rotating rod 23 is inclined downwards, and the end of the elastic abutment plate 801 away from the rotating rod 23 is arc-shaped.

[0045] When the linkage component drives the rotating rod 23 to rotate, it drives the arc-shaped pressing plate 302 to press down synchronously. The elastic pressing plate 801 moves down and contacts the inner wall of the inner circle of the annular metal material. Since the end of the elastic pressing plate 801 away from the rotating rod 23 is inclined downward and is arc-shaped, it will first lightly touch the inner wall of the material's inner circle with its arc-shaped end at the moment of contact. Then, as the arc-shaped pressing plate 302 continues to press down, the elastic pressing plate 801 deforms due to its own elasticity, gradually unfolds along the inner wall of the material's inner circle and applies a uniform pressing force. This method of point contact followed by surface contact can not only avoid direct hard pressure damage to the material surface, but also enhance the pressing effect through the continuous tension generated by elastic deformation, effectively preventing material displacement during welding. After welding is completed, the rotating rod 23 rotates in the opposite direction, the arc-shaped pressing plate 302 is lifted, and the elastic pressing plate 801 gradually returns to its original shape, releasing the pressing force on the material.

[0046] Working principle: A circular metal material is placed on the placement plate 16. When the material falls, it presses the two inserts 202, causing them to move within the slot and compressing the buffer spring 203. The elastic force of the buffer spring 203 provides a continuous clamping force to the inserts 202, ensuring the metal material is firmly supported. Pressing down on the placement plate 16 causes the insert rod 18 to move down within the sleeve 17. When the insert rod 18 reaches the bottom, the insert rod 21 passes through the opening and inserts into the slot, locking the placement plate 16 and preventing it from shaking during welding, which could affect the welding process. Simultaneously, when the placement plate 16 is pressed down, the racks on both sides of the toothed plate 402 mesh with the gear 401 fixed on the rotating rod 23. As the placement plate 16 moves down, the toothed plate 402... As the placement plate 16 moves upward, the gears 401 on both sides rotate synchronously. The gears 401 drive the rotating rod 23 to rotate, and the folding rod 301, which is fixedly connected to the rotating rod 23, rotates accordingly. The folding rod 301 drives the arc-shaped clamping plate 302 at its end to rotate and press down around the axis of the rotating rod 23. As the arc-shaped clamping plate 302 rotates, it gradually presses the material surface to ensure the stability of the material position during welding. If welding is required on the top or side of the metal material, the rotating motor 10 is started, driving the mounting head 11, mounting plate 15, and placement plate 16 to rotate in the vertical direction, so that the metal material is in a suitable welding position. The rotating motor 2 14 is started, driving the mounting plate 15 and placement plate 16 to rotate. Finally, the laser welding gun 13 is supported by the sliding component 1 on the top support 1. 2. Slide the upper part of the metal plate and adjust its position according to the size of the metal material to perform welding operations. After welding is completed, the rotating motor 10 drives the support plate 9 to return to a horizontal state. When the rotating motor 2 14 starts and drives the mounting plate 15 to rotate, the connecting rods 501 fixed on both sides of the mounting plate 15 rotate accordingly. The connecting rods 501 drive the connecting rods 502 at both ends to make circular motion around the rotation center of the mounting plate 15, so that the connecting rods 501 are aligned with the limiting plate 504. The rotating motor 10 is started again to drive the support plate 9 to rotate. The two connecting rods 502 gradually contact one end of the limiting plate 504. Due to the semi-circular setting of one end of the limiting plate 504 and the T-shaped setting of the two connecting rods 502, the limiting plate 504 hooks the two connecting rods. Then, under the blocking action of the limiting plate 504, the direction of movement is changed, thereby pulling the connecting rod 501 to move outward. At the same time, since the two limiting plates 504 are located above and below the connecting rod 501 respectively, both sleeves 20 rotate in the same direction. The connecting rod 501 is connected to the sleeve 20, thereby causing the sleeve 20 to slide outward between the mounting blocks 19, so that the insertion rod 21 disengages from the slot 1 of the insertion rod 18. Then, the buffer spring 603 releases its elastic potential energy, pushing the sleeve 602 to drive the placement plate 16 to rise and reset smoothly. Its continuous supporting force ensures that the placement plate 16 rebounds slowly, avoiding material shaking and ensuring stable loading and unloading of metal materials. This drives the clamping assembly to reset and drives the rotating rod 23 to rotate.The bending rod 301 drives the arc-shaped clamping plate 302 to lift simultaneously, releasing the pressure on the metal material. At this time, the mounting plate 15 is at a certain tilt angle, and the metal material is held in place by the supporting material. The operator can directly remove the annular metal material in a direction perpendicular to the placement plate 16. The buffer spring 203, having lost pressure, resets, pushing the insert block 202 to move. This facilitates loading and unloading operations and improves the continuous operation capability and production efficiency of the welding equipment.
