Description

Technical Field

[0001] This utility model relates to the field of laser welding technology, specifically to a laser welding workbench. Background Technology

[0002] Laser welding is a highly efficient and precise welding method that uses a high-energy-density laser beam as a heat source. It is an important aspect of laser material processing technology. By controlling parameters such as the width, energy, peak power, and repetition frequency of the laser pulse, the workpiece is melted to form a specific molten pool. Due to its unique advantages, it has been successfully applied to the precision welding of micro and small parts as well as the welding of bent parts in bending machines.

[0003] Modern fully automated laser welding involves tight welding, requiring high-precision positioning systems (such as machine vision technology) to ensure accurate welding position. Therefore, when placing the workpiece to be welded, it needs to be positioned precisely within the working area of ​​the laser welding device. Current positioning methods involve setting multiple stops on the top of the welding table, with the stops matching the shape of the workpiece. During welding, the workpiece can be directly placed within the space enclosed by the stops. While this method is simple and fast, the positions of the stops cannot be adjusted, and when changing the workpiece, the original stops can no longer perform their positioning function. Therefore, we propose a new laser welding table. Utility Model Content

[0004] This invention provides a laser welding worktable that has the advantage of being able to position workpieces of any shape, thus solving the problems mentioned in the background art.

[0005] The technical solution of this utility model is implemented as follows: A laser welding workbench is designed, including a workbench, the top of which is provided with a groove plate for placing the workpiece to be welded. This utility model also includes several positioning units, each positioning unit including a rectangular seat, a support screw is vertically installed in the middle of the top surface of the rectangular seat, a support tube is movably sleeved on each support screw, and a stop is provided on the side of the support tube.

The rectangular seats are respectively placed in the groove on the top surface of the groove plate, and a locking device is threaded on the top of the support screw to press the support tube tightly against the top surface of the groove plate.

[0006] Preferably, the groove at the top of the slot plate is a T-shaped groove, and the width of the rectangular seat is smaller than the width of the opening at the top of the T-shaped groove, but the length of the rectangular seat is longer than the width of the opening at the top of the T-shaped groove, so that the rectangular seat can be placed inside the T-shaped groove from the top.

[0007] Preferably, a pressure plate is coaxially provided at the bottom of the support tube to increase the contact area between the support tube and the groove plate.

[0008] Preferably, the side of the support tube is connected to the stop via a strip arm.

[0023] The technical solution of this utility model will be clearly and completely described below with reference to its embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0024] Reference Figures 1 to 7 This utility model provides a technical solution: a laser welding worktable, including a worktable 1, as shown in the figure. Figure 1 and Figure 2 As shown, at least one six-axis robotic arm 10 is installed on the top edge of the worktable 1. A laser welding device 9 (laser welding gun) is provided on the free end of the six-axis robotic arm 10. The worktable 1 is within the area of ​​the six-axis robotic arm 10, that is, the six-axis robotic arm 10 can drive the laser welding device 9 to any point on the surface of the worktable 1. An installation cabinet 11 is also installed below the workbench 1. The installation cabinet 11 is used to install the power supply for the laser welding device 9 and the control system for controlling the entire equipment, such as a PLC control system or a control host.

[0025] Furthermore, such as Figure 1 and Figure 2 As shown, the top of the workbench 1 is provided with a slot plate 12 for placing the workpiece 8 to be welded. The slot plate is also called a slot platform. The slot plate 12 is existing technology and is widely used in machine tools. The slot at the top of the slot plate 12 is a T-shaped slot. In reality, slotted plates are used to install clamps. In this application, the slotted plate 12 serves the same purpose. Therefore, several positioning units are provided on the slotted plate 12. Each positioning unit includes a rectangular seat 16. A support screw 7 is vertically installed in the middle of the top surface of the rectangular seat 16. The rectangular seats 16 are respectively placed in the slots on the top surface of the slotted plate 12. A locking device for pressing the support tube 5 against the top surface of the slotted plate 12 is threaded on the top of the support screw 7. The locking device is a locking nut 6. The locking nut 6 is a Phillips head knob or a hexagonal knob. A Phillips head knob is easy to hold by hand, while a hexagonal knob is easy to tighten with a wrench. In practical applications, the rectangular seat 16 can be entered from both ends of the T-slot, which is a rather cumbersome process. To allow the rectangular seat 16 to be better installed within the T-slot, this application specifically designs the width of the rectangular seat 16 to be smaller than the width of the top opening of the T-slot, and the length of the rectangular seat 16 to be longer than the width of the top opening of the T-slot, enabling the rectangular seat 16 to be placed inside the T-slot from the top. Therefore, when installing the support screw 7, simply align the rectangular seat 16 with the top opening of the T-slot, then place the rectangular seat 16 directly inside the T-slot, and then rotate the rectangular seat 16 as needed. Figure 7 As shown in the figure, the two ends of the rectangular base 16 can be fixed by engaging the T-slots. At this time, the rectangular base 16 can be firmly placed in the T-slots. A support tube 5 is movably fitted onto each support screw 7. The bottom diameter of the support tube 5 is larger than the width of the top opening of the T-slot to prevent the support tube 5 from also entering the T-slot. Figure 7 As shown, in reality, a pressure plate 18 can be coaxially provided at the bottom of the support tube 5. The pressure plate 18 is used to increase the contact area between the support tube 5 and the groove plate 12. A stop 4 is provided on the side of the support tube 5.

[0026] Furthermore, such as Figure 4 As shown, the side of the support tube 5 is connected to the stop 4 via the strip arm 3. Several stops 4 surround the side of the workpiece 8 to be welded and the two are in contact with each other. Since each stop 4 can rotate under the rotation of the support tube 5, the stop 4 can be adjusted in any direction. Therefore, it can be said that the space enclosed by the stop 4 is consistent with the spatial shape of the workpiece 8 to be welded. When the workpiece 8 to be welded is placed inside the space, it can be positioned.

[0027] Furthermore, to facilitate the adjustment of the stop 4, this application has also made improvements to the strip arm 3, such as... Figure 5 and Figure 6 As shown, the strip arm 3 is long and narrow to allow for sufficient adjustment space. An adjustment groove 2 is provided on the strip arm 3, and the adjustment groove 2 is fastened to the support 14 by a locking bolt 13. The locking bolt 13 is either a Torx bolt or a hex bolt; the Torx bolt is easy to grip by hand, while the hex bolt is easy to tighten with a wrench. The locking bolt 13 presses the strip arm 3 firmly onto the stop 4. One end of the support 14 is mounted on the side of the support tube 5. Figure 5 As shown, the support 14 has a placement groove 17 at its end. The strip arm 3 is movably placed in the placement groove 17. The size of the placement groove 17 matches the size of the strip arm 3, so the strip arm 3 can only move along the placement groove 17 without slipping. When the locking bolt 13 is loosened, the strip arm 3 can be adjusted back and forth.

[0028] Based on the above embodiments, further optimizations can be made, wherein the stop 4 is perpendicular to the groove plate 12, and a guide slope 15 is provided at the corner of the top of the stop 4 near the part to be welded 8. The guide slope 15 can increase the size of the top opening of the space enclosed by several stop 4s, which makes it easier to put the part to be welded 8 into it.

[0029] Based on the above embodiments, it should be further explained that the part to be welded 8 is a box body formed by bending machine, such as... Figure 3 As shown, the four corners of the box (such as...) Figure 3 (The area indicated by the middle arrow A) needs to be welded into shape, so this application allows the four corners of the box to be exposed through the space enclosed by the stop 4. The six-axis robotic arm 10 can drive the laser welding device 9 to weld the weld from the outside or inside of the box.

[0030] Based on the above embodiments, it should be further explained that the part to be welded 8 can also be an irregularly shaped part, because the stop 4 can be placed in any position, so that multiple stop 4 can be arranged into any shape. Therefore, when the part to be welded 8 is an irregularly shaped part of any shape, it can be positioned.

[0031] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
