[0009] In one possible implementation, the unloading device includes: A switch plate, which is hinged to the left side of the slide table; The telescopic plate is snapped onto the inner surface of the left side of the base, and a support is fixedly connected to the left side of the telescopic plate. The guide rod is fixedly connected to the right side of the telescopic plate.

[0010] In one possible implementation, the unloading device further includes: A locking plate is fixedly connected to the left side of the limiting frame, and a sliding rod is slidably connected to the inner surface of the locking plate; The lower locking plate is fixedly connected to the left side of the switch plate, and a locking shaft is snapped into the inner surface of the lower locking plate; A coupling is fixedly connected to the top of the slide rod; A trapezoidal top block, which is fixedly connected to the bottom end of the slide rod; A trapezoidal stop block is fixedly connected to the front and rear sides of the upper surface of the base.

[0011] In one possible implementation, the front and rear sides of the switch plate abut against the limiting frame, a torsion spring is provided at the hinge of the switch plate and the slide table, the telescopic plate is engaged with the inner surface of the left side of the base, the guide rod is slidably connected to the inner surface of the base, the upper surface of the lower locking plate abuts against the lower surface of the upper locking plate, the connecting shaft and the top of the locking shaft are fixedly connected, the locking shaft is slidably connected to the inner surface of the upper locking plate, a spring is provided between the upper surface of the trapezoidal top block and the lower surface of the upper locking plate, and the upper inclined surface of the trapezoidal stop block abuts against the lower inclined surface of the trapezoidal top block.

[0012] In one possible implementation, the internal support device includes: The slide rail is provided on the front and rear sides of the welding table, and a lifting slider is slidably connected to the inner surface of the slide rail. A support roller is hinged to the inner surface of the lifting slider.

[0013] In one possible implementation, the internal support device further includes: A limiting guide rail is fixedly connected to the front and rear sides of the upper surface of the base, and a horizontal slider is slidably connected to the surface of the limiting guide rail. The L-shaped connecting rod is fixedly connected to one side surface of the horizontal slider; A locking rod is slidably connected to the inner surface of the right side of the slide rail, and an abutment plate is fixedly connected to the right end of the locking rod; A convex plate is fixedly connected to the front and rear sides of the upper surface of the limiting frame, and a U-shaped top rod is fixedly connected to the inner surface of the convex plate.

[0014] In one possible implementation, the bottom end of the slide rail is rotatably connected to the upper surface of the second horizontal slider, the right end of the L-shaped connecting rod is fixedly connected to the left side of the second horizontal slider, the lower surface of the second horizontal slider abuts against the upper surface of the base, the contact plate abuts against the side of the slide rail away from the support roller, a spring is provided between the contact plate and the right side of the slide rail, and the locking rod is engaged with the inner surface of the lifting slider.

[0015] Compared with the prior art, the beneficial effects of the present invention are: 1. The limiting frame can limit the stainless steel plate within a certain range. Under the clamping and pushing force of the clamping rods and the abutment rods on both sides, the stainless steel plate moves to the center of the slide table, so that the two sections of stainless steel plate are quickly centered without the need for extra adjustments, improving work efficiency and welding accuracy. The abutment rod, affected by the interaction force, can automatically fit against the side surface of the stainless steel plate, thus clamping stainless steel plates of different widths and pushing them to center on the slide table, improving the applicability of the device. When the clamping rod is obstructed by the fixed stop, it cannot continue to move, thus changing its elastic clamping of the stainless steel plate to rigid clamping, increasing the clamping force and ensuring the stability during welding. When the left slide table sweeps past the movable stop, it moves to the left and in the opposite direction controlled by the electric guide rail, so that the clamping rod abuts against the movable stop and strengthens the clamping force, ensuring that the clamping force of the left and right sections of stainless steel plate is consistent. The horizontal slider drives the movable stop to move to the left, thereby expanding the limiting range, facilitating the welding of stainless steel plates of different lengths, and further improving the applicability of the device.

[0016] 2. After the stainless steel plate is pushed, its left end switch plate slides down, automatically moving away from the base. Automatic unloading is achieved without fully lifting the stainless steel plate, improving the ease of use. The left end of the stainless steel plate is caught by the support after falling, preventing hard contact with the ground and enhancing protection. When the telescopic plate moves to the left, it pulls the free end of the telescopic rod to extend to the left and stretches the internal spring, making the movement smoother and buffering the unloading of the stainless steel plate. The locking shaft slides upward within the upper locking plate and pulls away from the lower locking plate, quickly unlocking the lower locking plate and switch plate. At this time, the switch plate rotates open due to the torsion spring at its hinge with the slide table, allowing the device to unload the stainless steel plate. The guide rod drives the locking shaft downward through the connecting shaft and inserts into the lower locking plate to lock it, quickly closing the switch plate. This provides all-around limitation of the stainless steel plate, further improving the ease of use.

[0017] 3. The support roller can support the curved stainless steel plate, preventing it from collapsing before welding is complete and causing welding errors. This improves the welding effect of the device on curved stainless steel plates. The lifting slider drives the support roller to rise and fit against the inner arc top of the stainless steel plate, thus automatically supporting it when the two sections of stainless steel plate are closed. This improves the ease of use of the device and allows it to support stainless steel plates with different curvatures, enhancing its applicability. The second horizontal slider always maintains the same distance from the first horizontal slider. When the second horizontal slider moves, it can drive the support roller to move horizontally left and right through the slide rail and the lifting slider, ensuring that the support roller is always located between the inner arc tops of the two sections of stainless steel plate. This ensures effective support for stainless steel plates of different lengths, further enhancing the applicability of the device. Attached Figure Description

[0020] The specific embodiments of the present invention will now be described in detail with reference to the accompanying drawings, but it should be understood that the scope of protection of the present invention is not limited to the specific embodiments.

[0021] like Figure 1-9As shown, one embodiment of the present invention is: a high-power laser welding workstation for stainless steel, including a base 1, a gantry frame 2 fixedly connected to the upper surface of the base 1, a laser welding machine 3 slidably connected to the upper surface of the crossbeam of the gantry frame 2, a welding table 4 fixedly connected to the inner surface of the base 1, electric guide rails 5 fixedly connected to the front and rear sides of the upper surface of the base 1, a sliding table 6 fixedly connected to the moving end of the upper surface of the electric guide rails 5, a limit frame 7 fixedly connected to the upper surface of the sliding table 6, an unloading device 8 disposed on the left side of the sliding table 6, the unloading device 8 being used to unload the welded stainless steel plate from the welding table 4 and the base 1, and an inner support device 9 disposed above the base 1, the inner support device 9 being used to support the arc-shaped... Stainless steel plates are used for support, making the loading and welding process more stable. The limiting frame 7 can limit the stainless steel plates within a certain range. Under the clamping and pushing force of the clamping rods 11 and the abutment rods 12 on both sides, the stainless steel plates move to the center of the slide table 6, allowing the two stainless steel plates to quickly align without unnecessary adjustments, improving work efficiency and welding accuracy. The slide table 6 includes an L-shaped through groove 10, which is formed on the side surface of the limiting frame 7. Clamping rods 11 are hinged to the front and rear sides of the inner surface of the L-shaped through groove 10. Abutment rods 12 are hinged to the end of the clamping rods 11 that extends into the limiting frame 7. A friction wheel 13 is hinged to the end of the abutment rod 12 away from the clamping rods 11. 12. Under the influence of interaction forces, it can automatically conform to the side surface of the stainless steel plate, thereby clamping stainless steel plates of different widths and pushing them to center on the slide table 6, improving the applicability of the device. The clamping rod 11 cannot continue to move due to the obstruction of the fixed stop 18, thus changing its elastic clamping of the stainless steel plate into rigid clamping, improving the clamping force and ensuring the stability during welding. The slide table 6 also includes a support plate 14, which is fixedly connected to the upper surface of the base 1. An electric lead screw 15 is rotatably connected to the inner surface of the support plate 14. A horizontal slider 16 is threadedly connected to the upper surface of the electric lead screw 15. A movable stop 17 is fixedly connected to the upper surface of the horizontal slider 16. The stop 18 is fixedly connected to the upper surface of the base 1. When the left slide 6 passes the movable stop 17, it moves to the left and in the opposite direction by the electric guide rail 5, so that the clamping rod 11 abuts against the movable stop 17 and strengthens the clamping force to ensure that the clamping force of the two stainless steel plates is consistent. A torsion spring is provided at the hinge of the clamping rod 11 and the L-shaped through groove 10, and a torsion spring is provided at the hinge of the abutment rod 12 and the clamping rod 11. The horizontal slider 16 is slidably connected to the upper surface of the base 1, and the top of the clamping rod 11 abuts against the movable stop 17. The horizontal slider 16 drives the movable stop 17 to move to the left, thereby expanding the limiting range, which facilitates the welding of stainless steel plates of different lengths and further improves the applicability of the device.

[0022] Working Principle: When welding an arc-shaped stainless steel plate, its bottom end is placed on the right-side slide table 6. The limiting frame 7 restricts the stainless steel plate within a certain range. Then, the electric guide rail 5 is activated, moving the right-side slide table 6 to the welding table 4. Next, the other section of stainless steel plate to be welded is placed on the left-side slide table 6. The electric guide rail 5 moves the left-side slide table 6 closer to the right-side slide table 6, bringing the two sections of stainless steel plates together. At this point, the gantry 2 and laser welding machine 3 are activated. The gantry 2 moves the laser welding machine 3 left, right, and back and forth, precisely controlling its position to ensure alignment between the laser welding machine 3 and the welding interface of the stainless steel plate. Once the laser welding machine 3 is aligned with the welding interface, a laser is emitted to weld it. Welding is then performed to complete the welding of the two curved stainless steel plates. After the bottom end of the stainless steel plate is placed on the slide table 6, the clamping rod 11, under the influence of the torsion spring, inserts one end into the limiting frame 7 close to the side surface of the stainless steel plate, and drives the abutment rod 12 close to the side surface of the stainless steel plate. The abutment rod 12 then drives the friction wheel 13 close to and fits against the side surface of the stainless steel plate. When the friction wheel 13 is continuously squeezed, the interaction force drives the abutment rod 12 to rotate and open along the hinge point with the clamping rod 11. The friction wheel 13 can reduce the friction between the abutment rod 12 and the stainless steel plate when it opens. At this time, both the clamping rod 11 and the abutment rod 12 are close to the stainless steel plate under the influence of the torsion spring, thus clamping it. The clamping thrust of the clamping rod 11 and the abutment rod 12 on both the front and rear sides of the stainless steel plate is... Under the influence of the sliding table 6, the stainless steel plates are moved to the center, allowing them to be quickly aligned without unnecessary adjustments, thus improving work efficiency and welding accuracy. Due to the interaction force between the clamping rod 11 and the abutment rod 12, they automatically conform to the side surface of the stainless steel plate, enabling the clamping of stainless steel plates of different widths and centering them on the sliding table 6, improving the applicability of the device. As the right-side sliding table 6 continues to move to the right, it drives the clamping rod 11 to move to the right until one end of the clamping rod 11 extends out of the limiting frame 7 and contacts the fixed stop 18. At this point, the sliding table 6 continues to move to the right, causing the clamping rod 11 to be obstructed and rotate along its hinge with the L-shaped through groove 10, thus conforming more closely to the side surface of the stainless steel plate. Once the clamping rod 11 is completely and tightly fitted with the stainless steel plate... When the fixed stop 18 obstructs its movement, it can no longer move, thus changing its elastic clamping of the stainless steel plate into a rigid clamping, improving the clamping force and the stability of the stainless steel plate after positioning, ensuring smoothness during welding. When the left and right slides 6 move to the right and pass the movable stop 17, the clamping rod 11 will be affected by the movable stop 17 and rotate and retract within the L-shaped through groove 10. When the left slide 6 passes the movable stop 17, it is controlled by the electric guide rail 5 to move to the left in the opposite direction, so that the clamping rod 11 abuts against the movable stop 17 and strengthens the clamping force, ensuring that the clamping force of the left and right stainless steel plates is consistent. When welding stainless steel plates of different lengths is required, the electric lead screw 15 is activated, and the electric lead screw 15 drives the horizontal slider 16 to move to the left.The horizontal slider 16 then moves the movable stop 17 to the left, thereby expanding the limiting range and facilitating the welding of stainless steel plates of different lengths, further improving the applicability of the device.

[0023] like Figure 1-9 As shown, in another embodiment of the present invention, based on the above embodiments, the unloading device 8 includes a switch plate 81, which is hinged to the left side of the slide table 6. A telescopic plate 82 is snapped onto the inner left side of the base 1. A support 83 is fixedly connected to the left side of the telescopic plate 82, and a guide rod 84 is fixedly connected to the right side of the telescopic plate 82. When the stainless steel plate is pushed, its left end slides off the switch plate 81, thereby automatically moving away from the base 1. Automatic unloading can be completed without fully lifting the stainless steel plate, improving the ease of use of the device. After the left end of the stainless steel plate falls, it is caught by the support 83, avoiding... The hard contact between the stainless steel plate and the ground enhances the protection of the stainless steel plate. The unloading device 8 also includes an upper locking plate 85, which is fixedly connected to the left side of the limit frame 7. A slide rod 89 is slidably connected to the inner surface of the upper locking plate 85. A lower locking plate 86 is fixedly connected to the left side of the switch plate 81. A locking shaft 87 is snapped into the inner surface of the lower locking plate 86. A connecting shaft 88 is fixedly connected to the top of the slide rod 89. A trapezoidal top block 810 is fixedly connected to the bottom of the slide rod 89. A trapezoidal stop block 811 is fixedly connected to the front and rear sides of the upper surface of the base 1. When the telescopic plate 82 moves to the left, it pulls the free end of the telescopic rod to the left. Extending and stretching the internal spring makes the movement smoother, providing a buffer during the unloading of the stainless steel plate. The locking shaft 87 slides upward within the upper locking plate 85 and pulls away from the lower locking plate 86, causing the lower locking plate 86 and the switch plate 81 to unlock quickly. At this time, the switch plate 81 rotates open due to the torsion spring at its hinge with the slide table 6, allowing the device to unload the stainless steel plate. The front and rear sides of the switch plate 81 abut against the limiting frame 7. A torsion spring is provided at the hinge between the switch plate 81 and the slide table 6. The telescopic plate 82 engages with the inner left surface of the base 1, and the guide rod 84 engages with the inner surface of the base 1. The sliding connection is achieved by the upper surface of the lower locking plate 86 abutting against the lower surface of the upper locking plate 85, the top ends of the connecting shaft 88 and the locking shaft 87 being fixedly connected, the locking shaft 87 being slidably connected to the inner surface of the upper locking plate 85, a spring being provided between the upper surface of the trapezoidal top block 810 and the lower surface of the upper locking plate 85, the upper inclined surface of the trapezoidal stop block 811 abutting against the lower inclined surface of the trapezoidal top block 810, and the guide rod 84 driving the locking shaft 87 to slide down through the connecting shaft 88 and insert it into the lower locking plate 86 to lock it, thereby enabling the switch plate 81 to close quickly, thus enabling all-round limiting of the stainless steel plate and further improving the ease of use of the device.

[0024] Working principle: After the two stainless steel plates are welded together, the left and right sliding tables 6 are driven to move to the left. When the left sliding table 6 approaches the leftmost end of the base 1, the switch plate 81 is opened. The switch plate 81 hangs down naturally, and its top end fits against the upper surface of the base 1 to form an inclined plane. At this time, the right sliding table 6 continues to move to the left, driving the limiting frame 7 to move to the left. The limiting frame 7 pushes the right end of the welded stainless steel plate, causing the stainless steel plate to move to the left as a whole. After being pushed, the left end of the stainless steel plate slides off the sliding table 6 and the switch plate 81, thus automatically moving away from the base 1. Automatic unloading can be completed without fully lifting the stainless steel plate, improving efficiency. The device is easy to use, and the stainless steel plate is caught by the support 83 after falling from the left end, avoiding hard contact between the stainless steel plate and the ground and improving the protection of the stainless steel plate. As the stainless steel plate continues to move to the left and detaches from the base 1, the support 83 continues to move to the left under the thrust of the stainless steel plate, and drives the guide rod 84 to slide within the base 1 through the telescopic plate 82, ensuring stable unloading. At the same time, when the telescopic plate 82 moves to the left, it pulls the free end of the telescopic rod to extend to the left and stretches the spring inside, thus making the movement smoother and buffering the unloading of the stainless steel plate. After unloading is completed, the telescopic plate 82 is subjected to the spring and the elasticity of the telescopic rod. The repositioning action causes the material to retract into the base 1, facilitating continuous unloading. When the left slide 6 moves to the left, it drives the lower locking plate 86 to move to the left. The lower locking plate 86 drives the locking shaft 87 to move to the left. The locking shaft 87 then drives the trapezoidal top block 810 to move to the left via the connecting shaft 88 and the slide rod 89. When the lower inclined surface of the trapezoidal top block 810 abuts against the upper inclined surface of the trapezoidal stop block 811, the trapezoidal top block 810 moves upward under the guiding effect of the inclined surface, causing the slide rod 89 to slide upward within the upper locking plate 85. When the slide rod 89 slides upward, it drives the connecting shaft 88 to move upward. The connecting shaft 88 then drives the locking shaft 87 to slide upward within the upper locking plate 85 and withdraw from the lower locking plate 811. Locking plate 86, which in turn allows lower locking plate 86 and switch plate 81 to unlock quickly. At this time, switch plate 81 is rotated open by the torsion spring at its hinge with slide table 6, thus enabling the device to unload the stainless steel plate. Conversely, switching plate 81 is brought together with limit frame 7, and then slide table 6 is controlled to move to the right. At this time, trapezoidal top block 810 moves downward to reset under the influence of spring force and drives guide rod 84 to slide down. Guide rod 84 then drives locking shaft 87 to slide down through connecting shaft 88 and insert into lower locking plate 86 to lock it, so that switch plate 81 closes quickly. This enables all-round limiting of stainless steel plate and further improves the ease of use of the device.

[0025] like Figure 1-9As shown, in another embodiment of the present invention, based on the above embodiments, the inner support device 9 includes a slide rail 91, which is disposed on the front and rear sides of the welding table 4. A lifting slider 92 is slidably connected to the inner surface of the slide rail 91. A support roller 93 is hinged to the inner surface of the lifting slider 92. The support roller 93 can support the arc-shaped stainless steel plate, preventing the stainless steel plate from collapsing before welding is completed, thus avoiding welding errors and improving the welding effect of the device on the arc-shaped stainless steel plate. The inner support device 9 also includes a limiting guide rail 94, which is fixedly connected to the front and rear sides of the upper surface of the base 1. A horizontal slider 95 is slidably connected to the surface of the limiting guide rail 94. An L-shaped connecting rod 96 is fixedly connected to the side surface of the horizontal slider 16. A locking rod 97 is slidably connected to the inner right side of the slide rail 91. An abutment plate 98 is fixedly connected to the right end of the locking rod 97. A protruding plate 99 is fixedly connected to the front and rear sides of the upper surface of the limiting frame 7. A U-shaped top rod 910 is fixedly connected to the inner surface of the protruding plate 99. The lifting slider 92 drives the support roller 93. The device rises and fits against the inner arc top of the stainless steel plate, thus automatically supporting it when the two stainless steel plates are closed, improving the ease of use of the device and enabling it to support stainless steel plates with different curvatures, thereby enhancing the device's applicability. The bottom end of the slide rail 91 is rotatably connected to the upper surface of the second horizontal slider 95, the right end of the L-shaped connecting rod 96 is fixedly connected to the left side of the second horizontal slider 95, the lower surface of the second horizontal slider 95 abuts against the upper surface of the base 1, the contact plate 98 abuts against the side of the slide rail 91 away from the support roller 93, a spring is provided between the contact plate 98 and the right side of the slide rail 91, the locking rod 97 is engaged with the inner surface of the lifting slider 92, the second horizontal slider 95 always maintains the same distance from the first horizontal slider 16, and when the second horizontal slider 95 moves, it can drive the support roller 93 to move horizontally left and right through the slide rail 91 and the lifting slider 92, thereby keeping the support roller 93 always between the inner arc tops of the two stainless steel plates, ensuring effective support for stainless steel plates of different lengths, and further enhancing the applicability of the device.

[0026] Working principle: Before bonding the two curved stainless steel plates, first move the right slide 6 to the right until the clamping rod 11 contacts the fixed stop 18 and stops. This moves one stainless steel plate to the right side of the welding table 4. At this time, control the slide rail 91 to rotate on the horizontal slider 95. When the slide rail 91 rotates, it drives the lifting slider 92 and the support roller 93 to rotate until the support roller 93 moves to the position between the upper surface of the welding table 4 and the inner curved surface of the stainless steel plate. Then, control the left slide 6 to move to the right until the two stainless steel plates are bonded. The support roller 93 is raised to the inner arc apex of the curved stainless steel plate. At this time, the support roller 93 can support the curved stainless steel plate, preventing it from collapsing before welding is completed, which would lead to welding errors and improve the welding effect of the device on the curved stainless steel plate. As the left slide table 6 moves to the right, it drives the limiting frame 7 to move to the right. The limiting frame 7 then drives the U-shaped top rod 910 to move to the right through the protruding plate 99. When the U-shaped top rod 910 contacts the contact plate 98, the U-shaped top rod 910 pushes the contact plate 98 to move to the right, abutting... The touch plate 98 then drives the locking rod 97 to slide to the right and pull away the lifting slider 92, so that the lifting slider 92 is unlocked from the slide rail 91. At this time, the lifting slider 92 is lifted by the telescopic rod between itself and the inner surface of the slide rail 91 and the spring in the telescopic rod. The lifting slider 92 then drives the support roller 93 to rise and fit against the inner arc top of the stainless steel plate, so as to automatically support it when the two stainless steel plates are closed, which improves the ease of use of the device and can support stainless steel plates with different curvatures, thus improving the applicability of the device. While adjusting the position of the horizontal slider 16, the horizontal slider 16 can drive the horizontal slider 2 95 to slide horizontally on the limit guide rail 94 through the L-shaped connecting rod 96, so that the horizontal slider 2 95 always maintains the same distance from the horizontal slider 16. When the horizontal slider 2 95 moves, it can drive the support roller 93 to move horizontally left and right through the slide rail 91 and the lifting slider 92, so that the support roller 93 is always located between the inner arc tops of the two stainless steel plates, ensuring effective support for stainless steel plates of different lengths, further improving the applicability of the device.
