Description

Technical Field

[0001] This utility model relates to the field of laser welding machine technology, and in particular to a material pressing component for a laser welding machine. Background Technology

[0002] In laser welding, the clamping assembly is one of the core components ensuring welding accuracy. It applies stable pressure to the workpiece via a clamping plate, preventing displacement due to thermal deformation or vibration during welding and ensuring precise weld positioning and uniform penetration. The lifting and pressing states of the clamping plate directly affect workpiece loading and unloading efficiency and welding quality, making them critical parameters that operators must monitor in real time.

[0003] In laser welding, existing clamping components mostly rely on mechanical transmission or pneumatic control. The lifting and pressing status of the clamping plate lacks intuitive indication. Operators need to indirectly judge its status by observing the workpiece position, listening to the equipment sound, or checking the control panel parameters. This indirect judgment method is prone to misoperation in mass production, such as starting welding when the clamping plate is not fully pressed, or forcibly picking up or placing the workpiece when it is not fully lifted. To avoid such problems, operators need to spend extra time to confirm the status, which not only slows down the production rhythm but also reduces the overall production efficiency. Utility Model Content

[0004] The purpose of this invention is to at least solve one of the technical problems existing in the prior art, and to provide a pressure assembly for a laser welding machine. This invention addresses the issue that in laser welding, existing pressure assemblies mostly rely on mechanical transmission or pneumatic control, and the lifting and pressing states of the pressure plate lack intuitive indicators. Operators must indirectly judge the status by observing the workpiece position, listening to the equipment sounds, or checking the control panel parameters. This indirect judgment method is prone to errors in mass production, such as starting welding before the pressure plate is fully pressed, or forcibly taking or placing the workpiece before it is fully lifted. To avoid such problems, operators need to spend extra time confirming the status, which not only slows down the production pace but also reduces the overall production efficiency.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a material clamping assembly for a laser welding machine, comprising: The processing table and the worktable surface are fixedly installed on the processing table.

[0020] Please see Figure 1-5This utility model provides a technical solution: a material clamping assembly for a laser welding machine, comprising: A processing table 1 and a worktable surface 3 are fixedly installed on the processing table 1; The material pressing indicator structure is located on the worktable surface 3; The pressing prompt structure includes a cylinder 4, a fixed plate 6, and a pressing plate 5. The telescopic end of the cylinder 4 passes through the worktable surface 3 and is rotatably connected to a connecting plate 9. Connecting parts 8 and 10 are rotatably connected to the outside of the connecting plate 9. Connecting part 8 is fixedly connected to the bottom of the worktable surface 3, and connecting part 10 passes through the worktable surface 3 and is connected to the pressing plate 5. The pressing plate 5 is located at the top of the worktable surface 3 and can press against the worktable surface 3. Two positioning plates 12 are fixedly connected to the top of the pressing plate 5. Rotating plates 13 are rotatably connected to the opposite surfaces of the two positioning plates 12. The fixed plate 6 is fixedly connected to the housing at the top of the worktable surface 3. A sliding groove 11 is opened inside the fixed plate 6. Through grooves 15 are opened on both sides of the fixed plate 6. Support shafts 17 are slidably connected inside the two through grooves 15. Sliding plates 14 are fixedly connected to the opposite surfaces of the two support shafts 17. A rotating groove 16 is opened at the top of the sliding plate 14. The top of the rotating plate 13 is rotatably connected inside the rotating groove 16.

[0021] The middle part of the pressure plate 5 is hollow, the inside of the sliding groove 11 is a "U" shape, the inside of the rotating groove 16 is a "C" shape, the bottom of the processing table 1 is fixedly equipped with four omnidirectional wheels for easy movement, and the top of the worktable 3 is equipped with a laser welding mechanism 2.

[0022] The pressure indication structure also includes a status indicator rod 7, a gear 18, and a toothed plate 19. The status indicator rod 7 is fixedly connected to the top of the sliding plate 14, the gear 18 is fixedly connected to the end of the corresponding support shaft 17 away from the sliding plate 14, and the toothed plate 19 is fixedly connected to one side of the fixed plate 6. The gear 18 and the toothed plate 19 are meshed together.

[0023] There are two material pressing prompt structures, which are symmetrically arranged on the worktable surface 3.

[0024] Furthermore, when using this device, if a pressing operation is required, cylinder 4 is activated, and its telescopic end moves downward. The downward movement of the telescopic end of cylinder 4 causes the connecting plate 9 to rotate. Through the linkage between connecting part 1 8 and connecting part 2 10, connecting part 2 10 moves upward, thereby causing the pressing plate 5 to lift upward. At this time, the workpiece to be welded can be placed on the worktable 3. After placement, the telescopic end of cylinder 4 moves upward, and through the above-mentioned linkage structure, the pressing plate 5 moves downward. Finally, the pressing plate 5 presses against the worktable 3, achieving the clamping and fixing of the workpiece.

[0025] During the operation of the pressure plate 5, the rotating plate 13, which is rotatably connected to the two positioning plates 12 on the top of the pressure plate 5, will move accordingly. When the pressure plate 5 moves up and down, the rotating plate 13 drives the sliding plate 14 to slide up and down in the sliding groove 11. The status indicator rod 7 is fixedly connected to the top of the sliding plate 14. As the sliding plate 14 slides, the status indicator rod 7 will also move up and down.

[0026] Meanwhile, gear 18 is fixedly connected to the end of the corresponding support shaft 17 away from the sliding plate 14. When the support shaft 17 slides with the sliding plate 14, it drives gear 18 to move. Since gear 18 is meshed with toothed plate 19 fixedly connected to one side of fixed plate 6, gear 18 rolls on toothed plate 19, so that gear 18 can drive sliding plate 14 to rotate in sliding groove 11 through support shaft 17. The operator can judge the pressing status of pressing plate 5 by observing the position of status indicator rod 7, providing the operator with more intuitive feedback on pressing status.

[0027] This case is based on an existing patent, and the improved and innovative structure of this case is added on top of it without changing the original structure of the existing patent. The existing patent can be referred to as patent publication (announcement) number: CN221047589U.

[0028] Through the linkage design between the status indicator rod 7 and the pressure plate 5, when the pressure plate 5 moves up and down, the status indicator rod 7 will rotate under the meshing of the gear 18 and the toothed plate 19. The operator can directly observe the position change of the status indicator rod 7 and intuitively judge the lifting or pressing state of the pressure plate 5, thereby simplifying the operator's judgment process. The operator can grasp the pressing status without repeatedly checking the workpiece or control panel parameters, shortening the confirmation time of a single operation, and indirectly improving the overall production efficiency of laser welding.

[0036] Connector 2 10: Passes through the worktable surface 3 and is connected to the pressure plate 5; when the cylinder 4 drives the connecting plate 9 to rotate, it moves upward or downward through the rotational connection with the connecting plate 9 and under the linkage of connector 1 8, thereby driving the pressure plate 5 to move up and down to complete the pressing and releasing actions.
