Description

Technical Field

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

[0002] In modern manufacturing, laser welding technology, as a highly efficient and precise joining method, is widely used in the welding and processing of metal materials. Laser welding machines, with their unique advantages such as high energy density, fast welding speed, small heat-affected zone, and ability to adapt to complex geometries, have become indispensable equipment in many industrial fields.

[0003] In existing laser welding technology, due to the uneven height of the welding point, it is difficult for the laser welding machine to maintain a constant focal length when moving along the set trajectory for welding. This causes instability in the laser beam focus, resulting in uneven welding in some areas, poor welding effect, and may lead to problems such as insufficient welding strength, discontinuous welds, missed welds or over-welding, which seriously affect product quality and reliability.

[0004] Therefore, those skilled in the art have provided a laser welding machine welding point processing structure to solve the problems mentioned in the background art. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a welding point processing structure for a laser welding machine. During use, this structure utilizes a roller at the front end of the laser welding head, along with a sliding rod, a measuring plate, and a laser rangefinder. The height of the welding head is measured in real-time and adjusted by an external PLC control system. This allows the laser welding head to dynamically adapt to changes in the workpiece surface height as it moves along a preset trajectory, effectively reducing focal point deviation caused by surface unevenness. This significantly improves welding stability and uniformity, ensuring high-quality welding results.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A welding point processing structure for a laser welding machine includes a frame, a connecting frame, and rollers. A sliding rod is fixedly connected to the upper middle part of the frame, and a ranging plate is fixedly connected to the upper end of the sliding rod. A first spring is sleeved on the outside of the sliding rod. Housings are fixedly connected to both sides of the two end faces of the frame. A second spring is provided inside each of the multiple housings. A limit rod is fixedly connected to the lower end of each second spring. Limit blocks are rotatably connected to the lower ends of both end faces of the frame. A rotating shaft is fixedly connected to both end faces of the rollers. A rotating sleeve is rotatably connected to the outside of each rotating shaft. A T-shaped block is fixedly connected to one end face of each of the two rotating sleeves. A laser rangefinder is provided on one side of the upper end of the connecting frame.

[0008] Through the above technical solution, when the structure is in use, by setting rollers at the front end of the laser welding head, and in conjunction with sliding rods, measuring plates and laser rangefinders, the height of the welding head is measured in real time and adjusted by an external PLC control system. This allows the laser welding head to dynamically adapt to the changes in the height of the workpiece surface when moving and welding along a preset trajectory, effectively reducing the focus deviation caused by uneven surfaces, thereby significantly improving the stability and uniformity of welding and ensuring high-quality welding results.

[0009] Furthermore, guide grooves are provided at the upper ends of both sides of the frame, and guide blocks are fixedly connected to both sides of the lower end of the connecting frame. One end of each of the two guide blocks extends into the interior of the guide groove and is slidably connected thereto.

[0010] The above technical solution enables the guide block to slide in the guide groove, which helps to achieve a stable guiding function, ensures that the frame moves more smoothly, reduces offset, and improves the accuracy and stability of the overall structure.

[0011] Furthermore, the lower end of the first spring is fixedly connected to the frame, and the upper end is fixedly connected to the connecting frame;

[0012] The above technical solution can provide stable elastic support, ensuring that the frame and the lower rollers can move stably along the surface of the welded object.

[0013] Furthermore, a connecting post is fixedly connected to one end face of the connecting frame, and a connecting plate is fixedly connected to one end face of the connecting post;

[0014] Through the above technical solution, the design of the connecting column and connecting plate enables the connecting frame to be firmly connected to the laser welding machine, ensuring that the connecting frame will not loosen or shift during use and maintain stability.

[0015] Furthermore, a pulling block is fixedly connected to the upper outer end of each of the plurality of limiting rods;

[0016] The above technical solution allows the pull block design to make it easier for workers to pull the limit lever, improving the comfort and convenience of operation.

[0017] Furthermore, multiple side end faces of the two T-blocks are respectively attached to one side end face of the frame and one side end face of the limiting block;

[0018] The above technical solutions can ensure a stable connection between the roller and the frame, prevent loosening or misalignment, and improve the stability and accuracy of the system.

[0019] Furthermore, one end of the sliding rod passes through the connecting frame and is slidably connected to the connecting frame;

[0020] The above technical solutions enable flexible relative motion while reducing frictional resistance, improving motion efficiency, and ensuring smooth operation during work.

[0021] This utility model has the following beneficial effects:

[0022] 1. This utility model proposes a welding point processing structure for a laser welding machine. In use, the structure sets a roller at the front end of the laser welding head, and works with a sliding rod, a measuring plate, and a laser rangefinder to measure the height of the welding head in real time and adjust it by an external PLC control system. This allows the laser welding head to dynamically adapt to the height changes of the workpiece surface when moving and welding along a preset trajectory, effectively reducing the focus deviation caused by surface unevenness, thereby significantly improving the stability and uniformity of welding and ensuring high-quality welding results.

[0023] 2. The present invention proposes a welding point processing structure for a laser welding machine. During use, the limiting block and the limiting rod pushed by the second spring stably limit the T-blocks on both sides of the roller, ensuring the stable use of the roller on the upper part of the frame. When the roller is damaged, the replacement operation is simplified, only the limiting rod and the limiting block need to be pulled and rotated. This design not only improves the working accuracy of the roller and the stability of the equipment, ensuring the continuity and stability of production, but also improves the maintainability of the equipment and reduces maintenance costs and production downtime.

[0031] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of specific embodiments. Obviously, the described specific embodiments are only a part of the specific embodiments of the present invention, and not all of them. Based on the specific embodiments of the present invention, all other specific embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] Reference Figure 1-5 The present invention provides a specific embodiment of a laser welding machine welding point processing structure, including a frame 1, a connecting frame 11, and rollers 16. A sliding rod 2 is fixedly connected to the upper middle part of the frame 1, a measuring plate 3 is fixedly connected to the upper end of the sliding rod 2, a first spring 4 is sleeved on the outside of the sliding rod 2, a housing 6 is fixedly connected to both sides of the two end faces of the frame 1, a second spring 7 is provided inside the multiple housings 6, a limit rod 8 is fixedly connected to the lower end of the second spring 7, a limit block 5 is rotatably connected to both sides of the lower end of the two end faces of the frame 1, a rotating shaft 17 is fixedly connected to both end faces of the rollers 16, a rotating sleeve 18 is rotatably connected to the outside of the rotating shaft 17, a T-shaped block 19 is fixedly connected to one side of the two rotating sleeves 18, and a laser rangefinder 12 is provided on one side of the upper end of the connecting frame 11.

[0033] When in use, this structure uses a roller 16 at the front end of the laser welding head, along with a sliding rod 2, a measuring plate 3, and a laser rangefinder 12, to measure the height of the welding head in real time and adjust it via an external PLC control system. This allows the laser welding head to dynamically adapt to changes in the height of the workpiece surface as it moves along a preset trajectory for welding, effectively reducing focal deviation caused by uneven surfaces. This significantly improves the stability and uniformity of the welding process, ensuring high-quality welding results.

[0034] Guide grooves 10 are provided on the upper part of both ends of the frame 1. Guide blocks 15 are fixedly connected to both sides of the lower end of the connecting frame 11. One end of each guide block 15 extends into the guide groove 10 and slides therein. The sliding of the guide blocks 15 in the guide groove 10 helps to achieve a stable guiding function, ensuring that the frame 1 moves more smoothly, reducing deviation, and improving the accuracy and stability of the overall structure. The lower end of the first spring 4 is fixedly connected to the frame 1, and the upper end is fixedly connected to the connecting frame 11, providing stable elastic support and ensuring that the frame 1 and the lower roller 16 can move stably along the surface of the welded object. A connecting post 13 is fixedly connected to one end of the connecting frame 11, and a connecting plate 14 is fixedly connected to one end of the connecting post 13. The connecting post 13 and the connecting plate 14 are connected together. The design allows the connecting frame 11 to be firmly connected to the laser welding machine, ensuring that the connecting frame 11 will not loosen or shift during use and maintain stability. Pull blocks 9 are fixedly connected to the upper outer ends of multiple limit rods 8. The design of the pull blocks 9 makes it easier for the operator to pull the limit rods 8, improving the comfort and convenience of operation. Multiple side ends of the two T-shaped blocks 19 are respectively attached to one side end of the frame 1 and one side end of the limit block 5, which can ensure a stable connection between the roller 16 and the frame 1, prevent loosening or misalignment, and improve the stability and accuracy of the system. One end of the sliding rod 2 passes through the connecting frame 11 and is slidably connected to the connecting frame 11, which can realize flexible relative movement, reduce frictional resistance, improve movement efficiency, and ensure smooth operation during work.

[0035] Working Principle: During use, this structure utilizes a roller 16 at the front end of the laser welding head. As the welding head moves along a preset trajectory, the height change of the workpiece surface is measured in real time, causing the sliding rod 2 to rise and fall. This is further measured in real time by the measuring plate 3 and the laser rangefinder 12. An external PLC control system adjusts the welding head height dynamically, ensuring the laser beam maintains a stable distance from the welding position. This prevents focus deviation caused by uneven workpiece surfaces, improving welding quality and stability. Furthermore, the limiting block 5 limits the T-blocks 19 on both sides of the roller 16, and, in conjunction with the limiting rod 8 pushed by the second spring 7, ensures the roller 16 remains in a stable position during use, preventing displacement or loosening due to vibration or external force. This improves the working accuracy of the roller 16 and the stability of the equipment. When the roller 16 is damaged, it can be replaced by pulling the limiting rod 8 and rotating the limiting block 5, simplifying maintenance and replacement processes, reducing downtime and manual intervention, improving equipment maintainability, and lowering repair costs and production stoppages caused by roller 16 damage.
