Description

Technical Field

[0001] This utility model relates to the field of steel plate welding technology, and specifically to a steel plate welding equipment. 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. Laser welding is one of the important applications of laser material processing technology. Due to its unique advantages, it has been successfully applied to the precision welding of micro and small parts.

[0003] Chinese Patent No. CN221538474U discloses a fixture for laser welding stainless steel plates, which effectively solves the problem of difficult positioning when welding steel plates at various angles. It includes a first base plate and a second base plate hinged together, with an included angle of 30°-150°. Both ends of the first and second base plates are equipped with clamping mechanisms, each including a rotating seat with a sliding seat and a clamping plate slidably mounted on the sliding seat. The clamping plate is used to clamp the steel plate. This invention has a simple and ingenious structure. By changing the angle between the two hinged base plates, the angle between the welded steel plates can be determined, enabling welding positioning of steel plates at different angles and ensuring that the included angle of the steel plates meets production requirements.

[0004] However, in the above technical solution, the angle between the welded steel plates is determined by changing the angle between the two hinged base plates, and the welding positioning of steel plates at different angles is achieved to ensure that the included angle of the steel plates meets the production requirements. However, when using this device, the steel plates need to be clamped and fixed by rotating the bolts on the F-shaped clamping plate. The large contact area between the clamping plate and the steel plate results in poor heat dissipation, which can easily lead to accelerated thermal fatigue of the clamping plate and cause local tempering of the plate.

[0016] Example 1 like Figures 1-4 As shown, the present invention proposes a steel plate welding device, including a support base 1, ear plates 2, support plates 3, an angle adjustment assembly, and a clamping assembly. Two symmetrically arranged ear plates 2 are connected to the upper end face of the support base 1. A support shaft is connected to the ear plates 2, and two support plates 3 are connected to the support shaft. The angle adjustment assembly is connected to the support base 1. When the angle adjustment assembly is in use, the moving end of the angle adjustment assembly moves horizontally towards each other, pushing the support plates 3 to rotate synchronously around the support shaft. Multiple clamping assemblies are provided, and multiple parallel clamping assemblies are symmetrically arranged on the support plate 3. The clamping assembly includes an eccentric wheel 4, a fixed clamping rod 5, a movable clamping rod 6, a fixed seat 7, and an adjusting screw 8. The fixed seat 7 is bolted to the support plate 3. The fixed seat 7 is a split design, and the adjusting screw 8 is connected to the two parts of the fixed seat 7. In an optional embodiment, the fixed base 7 consists of a support base 9 and a U-shaped frame 10. The adjusting screw 8 passes through the U-shaped frame 10 and is rotatably connected to the support base 9. A limiting rod is connected to the support base 9 and is symmetrically arranged with the adjusting screw 8. The limiting rod is slidably connected to the U-shaped frame 10. The adjusting screw 8 is connected to an adjusting handle. The eccentric wheel 4 is rotatably connected to the fixed base 7. A handle is connected to the eccentric wheel 4. The fixed clamping rod 5 is connected to the fixed base 7. The movable clamping rod 6 is slidably connected to the fixed base 7. One side of the movable clamping rod 6 is slidably connected to the eccentric wheel 4. When the clamping assembly is in use, the eccentric wheel 4 rotates to push the movable clamping rod 6 close to the fixed clamping rod 5 for quick assembly and disassembly. The split fixed base 7 itself changes, causing the initial position of the fixed clamping rod 5 and the distance between the movable clamping rod 6 to change in order to adapt to various thicknesses of steel.

[0017] Example 2 like Figures 3-4 As shown, the steel plate welding equipment proposed in this utility model, compared with Embodiment 1, describes the detailed structure of the clamping assembly. The clamping assembly also includes a guide rod 11, a sliding block 12 and an elastic element 13. One end of the guide rod 11 is connected to the U-shaped frame 10, and the sliding block 12 is connected to the guide rod 11. The sliding block 12 is connected to one end of the movable clamping rod 6. The elastic element 13 is sleeved on the outside of the guide rod 11 and is disposed between the U-shaped frame 10 and the sliding block 12. The elastic element 13 is selected from, but is not limited to, a spring.

[0018] Example 3 like Figures 1-2 As shown, the steel plate welding equipment proposed in this utility model, compared with Embodiment 2, describes the detailed structure of the angle adjustment component. The angle adjustment component includes a bidirectional screw 14, an adjustment handle 15, a sliding seat 16, a sliding rod 17, and a guide plate 18. The two ends of the bidirectional screw 14 are rotatably connected to the mounting seats, which are connected to the support base 1. Any end of the bidirectional screw 14 passes through the mounting seat and connects to the adjustment handle 15. Two sliding seats 16 are symmetrically arranged, and the sliding seats 16 are threadedly connected to the bidirectional screw 14. The number of sliding rods 17 corresponds to the number of sliding blocks 12, and the sliding rods 17 are connected to the sliding blocks 12. The guide plates 18 are symmetrically arranged at both ends of each support plate 3. The guide plates 18 are provided with inclined guide grooves 19, and the two ends of the sliding rods 17 are slidably connected in the guide grooves 19.

[0019] In an optional embodiment, a protective plate 20 is provided on the support base 1, and a receiving groove is provided on the protective plate 20; the protective plate 20 is parallel to the support base 1, and both ends of the protective plate 20 are connected to the ear plate 2, and an arc-shaped groove is provided on the upper surface of the protective plate 20 to protect the bidirectional screw 14.

[0020] In an optional embodiment, both the fixed clamping rod 5 and the movable clamping rod 6 are threaded with protective sleeves 21; the protective sleeves 21, by virtue of their removability, can protect the two clamping components and prevent welding slag from adhering to their surfaces and affecting subsequent welding and clamping.

[0021] In an optional embodiment, an angle ruler 22 is connected to each of the two ear plates 2. The center of the angle ruler 22 is the same as the connecting shaft. An indicator mark is provided on each of the support plates 3. When the two support plates 3 rotate, the indicator marks on both sides of them also rotate. Both can indicate the current angle on the angle ruler 22.

[0022] In summary, when using this utility model, the worker places the steel plate above the fixed clamping rod 5, and then rotates the adjusting handle to drive the eccentric wheel 4 to rotate, causing it to press the sliding block 12, which moves along the guide rod 11 to compress the elastic element 13. The movable clamping rod 6 on the sliding block 12 approaches the fixed clamping rod 5 for clamping and fixing. When it is necessary to clamp steel of different thicknesses, the adjusting handle on the adjusting screw 8 can be used to drive it to rotate, thereby driving the U-shaped frame 10 to move vertically. Adjusting the distance between the support base 9 and the U-shaped frame 10 allows the movable clamping rod 6 to engage with the fixed clamping rod 5 when the eccentric wheel 4 rotates and locks itself. When the distance between rods 5 changes, and two steel plates need to be welded at different angles, the bidirectional screw 14 can be rotated by rotating the adjusting handle 15, which will cause the sliding seat 16 to move synchronously towards each other. The two ends of the sliding rod 17 on the sliding seat 16 contact the guide groove 19 on the guide plate 18. Due to the angle of the guide groove 19, when the sliding rod 17 moves horizontally, it will push the guide plate 18 and the support plate 3 to rotate around the support shaft, thereby adjusting the angle between the two steel plates. If it is necessary to weld steel plates of different sizes in some cases, the position of the fixing seat 7 can be changed by removing the bolts.

[0023] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
