Description

Technical Field

[0001] The utility model relates to the field of laser welding machines, in particular to a door ring laser welding machine. Background Art

[0002] Welding equipment is industrial equipment used to connect metal or thermoplastic materials. It creates a strong connection between workpieces by heating and applying pressure or filling materials on the joint surface. Welding equipment has different working principles and technical characteristics according to different application requirements and material properties. From small handheld equipment to large-scale automated production lines, there are corresponding welding equipment to choose from. These equipment are widely used in manufacturing, construction, automotive industry and other fields, and are one of the indispensable and important tools in modern industrial production. Laser welding is one of the important welding methods.

[0003] In traditional laser welding equipment, the welding power supply is the core component of the welding equipment, providing the required electrical energy for use in the welding process. Depending on the different welding methods, the welding power supply can be DC, AC or a specific waveform, such as an inverter welding power supply. The welding gun or welding pen is the component of the welding equipment that connects the power supply and the welding material. The welding gun contains electrodes or welding wires, and the on and off of the current is controlled by a trigger or switch to control the start and end of welding. The welding table or fixture is used to support and fix the welding workpiece to ensure the stability and accurate position of the workpiece during the welding process. The workbench or fixture usually has an adjustable function to accommodate workpieces of different sizes and shapes.

[0004] However, in traditional laser welding equipment, the welding workpiece is often placed directly on the workbench surface and lacks a fixed structure. This welding method may cause the welding workpiece to move during the welding process, which reduces the welding quality of the welding workpiece and is not conducive to high-quality laser welding. Utility Model Content

[0005] In order to make up for the above shortcomings, the utility model provides a door ring laser welding machine, which aims to improve the problem that in traditional laser welding equipment, the welding workpiece is often placed directly on the workbench surface and lacks a fixed structure. This welding method may cause the welding workpiece to move during the welding process, which reduces the welding quality of the welding workpiece and is not conducive to high-quality laser welding.

[0006] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a door ring laser welding machine, including a base, a plurality of fixed plates are fixedly connected to the top of the base, a plurality of fixed platforms are fixedly connected to the top of the base, a hydraulic rod is fixedly connected to the top of the fixed plate, a sliding column is fixedly connected to the output end of the hydraulic rod, a side plate is fixedly connected to the top of the fixed plate, a support platform is fixedly connected to the top of the side plate, a slide groove is opened inside the support platform, the outer wall of the slide column is slidably connected to the inside of the slide groove, and a connecting component is arranged on the top of the fixed platform, and the connecting component is used to connect the welding workpiece.

[0007] Furthermore, the connection assembly includes a supporting column, a plurality of supporting columns are fixedly connected to the top of the fixing platform, and a welding plate is provided on the top of the supporting column.

[0008] Furthermore, a turntable is fixedly connected to the upper surface of the support platform.

[0009] Furthermore, a rotating groove is provided inside the rotating table.

[0010] Furthermore, a connecting plate is provided on the side wall of the turntable.

[0011] Furthermore, the side wall of the connecting plate is rotatably connected inside the rotating groove.

[0012] Furthermore, a top block is fixedly connected to the top of the connecting plate.

[0013] Furthermore, a pressure column is fixedly connected to the side wall of the top block.

[0014] The utility model has the following beneficial effects:

[0015] 1. In the utility model, firstly, the hydraulic rod is used to pull the slide column so that the slide column slides inside the slide groove and pulls the connecting plate. At this time, the connecting plate rotates inside the rotating groove and the welding plate is effectively fixed by the pressure column. This structure avoids the problem that the welding workpiece may be displaced during the welding process, which reduces the welding quality of the welding workpiece and is not conducive to high-quality laser welding.

[0016] 2. In the utility model, the welding plate is pressed down by the pressure column and the welding plate is lifted up by the support column, so that the welding plate remains stable and the bottom remains hollow during the welding process. This structure ensures high-quality welding and improves the uniformity of welding products. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] Reference Figure 1 and Figure 2 The utility model provides an embodiment: a door ring laser welding machine, including a base 1, a plurality of fixed plates 5 are fixedly connected to the top of the base 1, a plurality of fixed platforms 2 are fixedly connected to the top of the base 1, a hydraulic rod 6 is fixedly connected to the top of the fixed plate 5, a sliding column 10 is fixedly connected to the output end of the hydraulic rod 6, a side plate 7 is fixedly connected to the top of the fixed plate 5, a support platform 8 is fixedly connected to the top of the side plate 7, a slide groove 9 is opened inside the support platform 8, the outer wall of the slide column 10 is slidably connected inside the slide groove 9, and a connecting component is arranged on the top of the fixed platform 2, and the connecting component is used to connect the welding workpiece.

[0024] Each door ring is formed by punching a plurality of sub-sheets (welding plates 4) together by laser welding.

[0025] Specifically, the hydraulic rod 6 is started first. The hydraulic rod 6 outputs a push-pull force through the slide column 10 on the top of the fixed plate 5. The slide column 10 therefore slides inside the slide groove 9 of the support platform 8. Its movement simultaneously pulls one end of the connecting plate 13, causing the connecting plate 13 to start rotating. The connection of the side wall of the connecting plate 13 on the turntable 11 causes it to change its inclination angle inside the turn groove 12. As the connecting plate 13 moves, the top block 14 on the top rotates synchronously with it. The movement of the top block 14 then drives the top pressure column 15 to move. The downward displacement of the pressure column 15 can ensure that the welding plate 4 is effectively fixed. This structural design effectively prevents the welding workpiece from being displaced during the laser welding process. This fixing method is crucial to ensuring the welding quality, especially when high-precision laser welding is required. Any displacement may affect the integrity and quality of the welded joint. Therefore, through the application of this mechanical structure, the stability and welding quality of the welding workpiece can be effectively improved, ensuring that each welding process can meet the expected high quality standards.

[0026] Reference Figure 3 The connecting component includes a supporting column 3, and multiple supporting columns 3 are fixedly connected to the top of the fixed platform 2. A welding plate 4 is arranged on the top of the supporting column 3. A turntable 11 is fixedly connected to the upper surface of the supporting platform 8. A rotating groove 12 is opened inside the turntable 11. A connecting plate 13 is arranged on the side wall of the turntable 11. The side wall of the connecting plate 13 is rotatably connected to the inside of the rotating groove 12. A top block 14 is fixedly connected to the top of the connecting plate 13, and a pressure column 15 is fixedly connected to the side wall of the top block 14.

[0027] Specifically, while the pressure column 15 fixes the welding plate 4, a plurality of support columns 3 are installed on the top of the fixing table 2. The design of these support columns 3 enables them to effectively support the welding plate 4, thereby keeping its bottom hollow while the welding plate 4 is fixed. This structural design is of great significance to welding quality and production uniformity. The function of the support columns 3 is to ensure that the welding plate 4 will not be deformed or unevenly conduct heat during the welding process due to the irregularity of the bottom contact surface. By keeping the bottom of the welding plate 4 hollow, the heat during the welding process can be distributed more evenly, avoiding unnecessary stress concentration or thermal deformation, thereby ensuring high quality of welding.

[0028] Working principle: When the welding plate 4 needs to be fixed, the hydraulic rod 6 is first started. The hydraulic rod 6 outputs a push-pull force to the slide column 10 at its output end at the top of the fixed plate 5. At this time, the slide column 10 can slide inside the slide groove 9 in the support platform 8 after being subjected to the force. The movement of the slide column 10 pulls the connecting plate 13 at one end thereof, so that the connecting plate 13 also rotates. Since the side wall of the connecting plate 13 is connected by rotation in the turntable 11, the connecting plate 13 changes its own inclination angle inside the rotating groove 12 at this time. Through the movement of the connecting plate 13, the top block 14 on its top follows the synchronous rotation. While the top block 14 moves, it drives the pressure column 15 on its top to move. The downward displacement of the pressure column 15 can achieve effective fixing of the welding plate 4. Fixed, this structure avoids the problem that the welding workpiece may be displaced during the welding process, which reduces the welding quality of the welding workpiece and is not conducive to high-quality laser welding. While the pressure column 15 fixes the welding plate 4, a plurality of support columns 3 are fixed on the top of the fixed platform 2. The fixation of the support columns 3 can support the welding plate 4, so that the bottom of the welding plate 4 remains hollow while being fixed. Because the bottom of the welding plate 4 is hollow when fixed, this ensures that the heat during the welding process can be evenly transferred and distributed to the entire welding joint, reducing the risk of deformation of the welding plate 4, thereby improving the consistency and quality stability of the welding plate 4. This structure ensures high-quality welding and improves the uniformity of welding products.
