Description

Technical Field

[0001] This application relates to the field of welding technology, and more particularly to a welding apparatus. Background Technology

[0002] A related technology (Announcement No.: CN220739802U) discloses a sheet metal laser welding machine, including a welding table. Supports are fixedly connected to both sides of the upper surface of the welding table. Limiting rods are fixedly connected to the top of the support sides. A sleeve is fitted onto the outer surface of the limiting rod, and a fixing block is fixedly connected to the lower surface of the sleeve. A longitudinal electric push rod is fixedly connected to the lower surface of the fixing block, and a welding head is connected to the moving end of the longitudinal electric push rod. A threaded rod is threaded into the fixing block, and the end of the threaded rod is fixedly connected to the output end of a servo motor. A transverse electric push rod is fixedly connected to the side of the support sides that are close to each other, and an L-shaped clamp is fixedly connected to the moving end of each transverse electric push rod.

[0003] In the process of implementing the technical solution disclosed herein, at least the following problems were found in the related technologies:

[0004] The sheet metal laser welding machine controls two horizontal electric push rods, which move the L-shaped clamping plates on both sides towards each other, thus clamping two sheet metal pieces. Then, driven by a servo motor and a vertical electric push rod, the welding head moves horizontally and vertically until the welding of the two sheet metal pieces is completed. However, during the clamping process, the position of the two sheet metal pieces must be manually adjusted so that the seam between them is directly below the welding head to complete the welding. Manual adjustment often requires multiple attempts to align the seam, making the operation rather cumbersome.

The bending plate 3 includes a horizontal wall and a vertical wall. The horizontal wall is connected to the moving end of the first linear slide 2, and the vertical wall is connected to the horizontal wall. The horizontal wall supports the plate 10 material, and the vertical wall is used to determine the initial coordinate position. The bending plate 3 moves along the length direction of the support platform 1 under the drive of the first linear slide 2. The first cylinder 4 is installed on the vertical wall along the height direction of the support platform 1, facing the horizontal wall, and provides driving force to press a plate. Mounting plate 5 is installed on the top surface of support platform 1. Along the length of support platform 1, mounting plate 5 and first linear slide 2 are located on both sides of support platform 1. Mounting plate 5 includes a notch for accommodating first pad 6 and another plate, and supports the mounting of second cylinder 7. First pad 6 is installed on the top surface of support platform 1 and located within the notch, for supporting and elevating another plate. The top surface of first pad 6 and the top surface of the horizontal wall are on the same plane, so that the two plates are in the same plane. Second cylinder 7 is installed on mounting plate 5 along the height direction of support platform 1 and faces first pad 6, for providing driving force to press the other plate. Laser welding gun 8 faces the top surface of support platform 1, along the length direction of support platform 1, and is located between first linear slide 2 and first pad 6, for welding the joint of the two plates. Driving component is installed between the top surface of support platform 1 and laser welding gun 8, for providing driving force to drive laser welding gun 8 to move along the width and height directions of support platform 1.

[0038] This disclosure provides a welding apparatus in which, during use, a plate is placed against a horizontal wall with its edge abutting against a vertical wall. The first cylinder 4 is then activated to press and fix the plate. The first linear slide 2 is then activated, moving the bending plate 3 along the length of the support platform 1. Ultimately, the plate is moved to a suitable position based on its width, ensuring its edge is directly below the laser welding gun 8. Another plate is then placed against the first pad 6 with its edge abutting against the fixed plate. The second cylinder 7 is then activated to press and fix the other plate. At this point, the seam between the two plates is directly below the laser welding gun 8 without requiring multiple adjustments. The drive mechanism is then activated, moving the laser welding gun 8 along the height and width of the support platform 1, ultimately maintaining a suitable distance between the laser welding gun 8 and the seam for welding.

[0039] Optionally, combined Figure 1 and Figure 5 As shown, the driving components include a support shaft 9, a support plate 10, a second linear slide 11, a moving plate 12, and a third linear slide 13. The support shaft 9 is mounted on the top surface of the support platform 1 along its height and on both sides of the bending plate 3 along its width. This design, with the support shaft 9 positioned on both sides of the bending plate 3, avoids interference with the pressed and fixed sheet metal. The support plate 10 is mounted on the top of the support shafts 9 on both sides to support the second linear slide 11. The second linear slide 11 is mounted on the support plate 10 along the width of the support platform 1 to provide driving force, enabling movement along the width of the support platform 1. The moving plate 12 is mounted on the moving end of the second linear slide 11 to support the third linear slide 13. The third linear slide 13 is mounted on the moving plate 12 along the height of the support platform 1 to provide driving force, enabling movement along the height of the support platform 1. The laser welding gun 8 is mounted on the moving end of the third linear slide 13.

[0040] In this embodiment, controlling the second linear slide 11 moves the movable plate 12 along the width of the support platform 1, ultimately moving the laser welding gun 8 along the width of the support platform 1. Controlling the third linear slide 13 moves the laser welding gun 8 along the height of the support platform 1. Therefore, by cooperating with the second linear slide 11 and the third linear slide 13, the laser welding gun 8 can automatically move along the height and width of the support platform 1, ultimately maintaining a suitable distance from the splicing line and automatically welding along the splicing line.

[0041] Optionally, combined Figure 1 and Figure 5 As shown, the driving component also includes a first guide rail 14 and a first slider 15. The first guide rail 14 is mounted on the support plate 10 along the width direction of the support platform 1.

[0046] In this embodiment, the second pad 16 serves to support and elevate the second guide rail 17 and the second slider 18 to adjust their positions. The second guide rail 17 and the second slider 18 serve as guide supports to improve the stability of the bending plate 3 during movement and reduce the force on the moving end of the first linear slide 2.

[0047] Optionally, combined Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, it also includes a first pressure plate 19. The first pressure plate 19 is installed on the moving end of the first cylinder 4 and is used to abut against the plate.

[0048] In this embodiment of the present disclosure, the first pressure plate 19 moves under the drive of the first cylinder 4 to abut against the plate, thereby increasing the contact area with the plate and thus improving the pressing and fixing effect on the plate.

The first retaining ring is installed at the top end of the first guide shaft 21 to serve as a limit.

[0050] In this embodiment, the first linear bearing 20 and the first guide shaft 21 together serve as guides and supports to improve the stability of the first pressure plate 19 during movement. The first retaining ring serves as a limit to prevent the first guide shaft 21 from falling out of the first linear bearing 20.

[0051] Optionally, combined Figure 1 , Figure 3 , Figure 4 and Figure 5As shown, it also includes a second pressure plate 22. The second pressure plate 22 is installed on the moving end of the second cylinder 7 and is used to abut against the plate.

[0052] In this embodiment of the present disclosure, the second pressure plate 22 moves under the drive of the second cylinder 7 to abut against the plate, thereby increasing the contact area with the plate and thus improving the pressing and fixing effect on the plate.

[0053] Optionally, combined Figure 1 , Figure 3 , Figure 4 and Figure 5 As shown, it also includes a second linear bearing 23, a second guide shaft 24, and a second retaining ring.
