[0003] A patent search revealed a document titled "A Cantilever Column for a Laser Welding Machine" (publication number "CN217913418U"). This document describes a device that improves the stability of the moving base and welding head along the cantilever rail by adding reinforcing ribs. However, when the moving base and welding head are displaced for extended periods, the strength of the reinforcing ribs decreases, causing changes in the levelness of the cantilever rail and consequently affecting the smoothness of the welding head's horizontal movement along the cantilever rail. Therefore, this invention designs a dual-rail anti-shake cantilever support structure for a laser welding machine to solve the aforementioned problems. Utility Model Content

Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0021] Example 1 A preferred embodiment of the dual-rail anti-shake cantilever bracket structure for the laser welding machine provided by this utility model is, for example... Figures 1 to 4The following describes a dual-rail anti-shake cantilever support structure for a laser welding machine: It includes an operating platform 1, a support plate 2 fixed to the top left side of the operating platform 1; rotating rods 3 rotatably disposed at both ends inside the support plate 2; a slide rail 4 threadedly sleeved on the upper end of the rotating rods 3; and a slider 5 threadedly sleeved on the upper end of the rotating rods 3; a correction assembly 6 assembled on the slider 5 and the slide rail 4, which adjusts the levelness of the slide rail 4. The correction assembly 6 includes a pull rod 601 rotatably disposed on the right side outside the slider 5, with a pull sleeve rotatably sleeved on the outside of the pull rod 601. 602; A connecting rod 603 with threads inside the pull rod 601, the connecting rod 603 being threadedly connected to the pull sleeve 602, and a support sleeve 604 rotatably sleeved on the right side outside the connecting rod 603; a mounting plate 605 fixed to the outer wall of the pull rod 601, a worm gear 606 being rotatably connected inside the mounting plate 605, a worm wheel 607 fixedly sleeved on the outside of the pull sleeve 602, a level 608 fixed to the outer wall of the slide rail 4, a slider 5 and the slide rail 4 being slidably connected to the support plate 2, the support sleeve 604 being rotatably connected to the slide rail 4, and the worm gear 606 meshing with the worm wheel 607.

[0022] It should be noted that the existing dual-rail anti-shake cantilever bracket structure of laser welding machines still has certain shortcomings in actual use. It cannot adjust the level of the slide rail, which causes the welding head to shake when it moves due to the deformation of the slide rail, thus affecting the welding effect of the welding head.

[0023] In this embodiment, the coordinated design of the pull rod 601, pull sleeve 602, connecting rod 603, and support sleeve 604 firstly places one end of the right cantilever of the slide rail 4 in a suspended state, thereby improving the horizontal strength of the slide rail 4 itself. When the slide rail 4 experiences a slight deformation that is not visible to the naked eye, the level value of the level 608 changes. By checking the level 608, the operator can rotate the worm gear 606. The worm gear 606 drives the worm wheel 607 to rotate the pull sleeve 602. Through the threaded transmission design between the pull sleeve 602 and the connecting rod 603, the connecting rod 603 pulls or pushes the support sleeve 604 to exert a pulling or pushing force on the right end of the slide rail 4. The connecting rod 603 moves along the direction of the pull rod 601. In this way, the levelness of the slide rail 4 is adjusted until the value of the level 608 meets the operator's needs. Then, the operator can release the worm gear 606.

[0024] In a further preferred embodiment of this utility model, a motor 7 is fixedly mounted on the top left side of the support plate 2. The output end of the motor 7 rotates through the support plate 2. The motor 7 is a geared motor. The output end of the motor 7 is fixedly connected to the rotating rod 3 on the left side. The bottom of the rotating rod 3 rotates through the operating table 1. A linkage component is provided outside the rotating rod 3. The linkage component can operate synchronously with the motor 7. The linkage component includes a pulley 8 fixedly sleeved on the lower end of the rotating rod 3; and a toothed belt 9 tightly fitted on the outside of the pulley 8, with the toothed belt 9 meshing with the teeth of the pulley 8.

[0025] In this embodiment, the operator can turn on the motor 7, which drives the rotating rod 3 to drive the pulley 8 and the toothed belt 9 to rotate synchronously. Through the design of the screw transmission between the rotating rod 3, the slide rail 4, and the slider 5, the slide rail 4 and the slider 5 can be raised and lowered along the longitudinal direction of the support plate 2, thereby adjusting the height of the slide rail 4.

[0026] Example 2 Based on Embodiment 1, a preferred embodiment of the dual-rail anti-shake cantilever bracket structure for the laser welding machine provided by this utility model is, for example... Figures 1 to 4 As shown: Slide plates 10 are slidably connected between each pair of slide rails 4. Mounting blocks 11 are slidably sleeved on the outside of slide plates 10. Slide plates 10 are perpendicular to slide rails 4. A limiting post 12 is fixed at the bottom center of mounting block 11. A rotating plate 13 is rotatably sleeved on the outside of limiting post 12. The rotating plate 13 is parallel to slide plates 10. A guide plate 14 is slidably connected inside the rotating plate 13. A welding head 15 is fixed inside the guide plate 14. The welding head 15 is a handheld laser welding head. A first top pin 16 is threaded on the left side inside the rotating plate 13. The first top pin 16 is perpendicular to the limiting post 12. A second top pin 17 is threaded on the side of the rotating plate 13 away from the first top pin 16. The second top pin 17 corresponds one-to-one with the guide plate 14.

[0027] In this embodiment, when the slide rail 4 is height adjusted, the slide rail 4 drives the sliding plate 10 and the welding head 15 to rise and fall. When the welding head 15 comes into close contact with the workpiece on the top surface of the operating table 1, the operator turns off the motor 7 and then pulls the sliding plate 10, causing the sliding plate 10 to move the welding head 15 left and right along the direction of the slide rail 4. The mounting block 11 can also move the welding head 15 forward and backward along the sliding plate 10. Furthermore, the operator can rotate the rotating plate 13, causing the rotating plate 13 to adjust the angle of the welding head 15 around the axis of the limiting post 12. The operator can push the welding head 15, causing the welding head 15 to move the guide plate 14 along the direction of the rotating plate 13. In this way, the welding head 15 can be moved, improving the convenience of using the welding head 15. After the angle of the rotating plate 13 and the displacement distance of the guide plate 14 are adjusted, the operator then rotates the first top pin 16 and the second top pin 17 in sequence. The first top pin 16 applies pressure to the limiting post 12, and the second top pin 17 applies pressure to the guide plate 14, thereby locking the adjusted state of the rotating plate 13 and the guide plate 14.

[0028] In summary, this application allows for the adjustment of the slide rail's level, ensuring its precise horizontal alignment. The coordinated use of the pull rod, pull sleeve, connecting rod, and support sleeve improves the stability of the connection between the slide rail and the rotating rod, preventing vibration during welding head displacement caused by slide rail deformation. The lifting function allows the welding head to move along the operating table, the angle adjustment function allows the welding head to rotate around the axis of the limiting column, and the telescopic function allows the welding area of ​​the welding head to be enlarged or reduced, improving the ease of use.
