Description
Technical Field
[0001] This utility model relates to the field of high-temperature preheating and welding technology, specifically a compact high-temperature preheating and welding collaborative mechanical system. Background Technology
[0002] In the field of machinery manufacturing, the efficiency and quality of welding processes have always been key concerns for the industry. As industrial production moves towards higher precision and efficiency, the traditional welding process, which separates preheating and welding, is gradually revealing problems such as long production cycles, high energy consumption, and large equipment footprint. Especially when dealing with new welding materials such as high-strength alloys and composite materials, traditional processes struggle to achieve precise and coordinated control of the preheating temperature field and welding heat input, leading to unstable weld joint performance and even defects such as cracks and porosity.
[0003] Meanwhile, modern manufacturing demands increasingly compact and intelligent production lines. Traditional welding equipment, with its dispersed structure and independent operation of each functional module, not only increases the difficulty of production line layout but also makes efficient integration with automated production lines challenging. In fields such as aerospace and automotive manufacturing, where welding quality requirements are extremely high, achieving integrated and coordinated operation of high-temperature preheating and welding processes within limited space has become a pressing technical challenge.
[0004] Furthermore, rising energy costs are prompting the industry to seek more energy-efficient welding solutions. In traditional step-by-step processes, preheating and welding equipment operate independently, resulting in significant energy waste. Developing a compact mechanical system that organically combines preheating and welding processes to achieve energy-efficient utilization is crucial for reducing production costs and enhancing industry competitiveness. Therefore, our compact high-temperature preheating and welding collaborative mechanical system addresses these issues. Utility Model Content

[0022] The present invention will now be described in detail, and the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present invention.
[0023] This utility model provides an improved compact high-temperature preheating and welding collaborative mechanical system. The technical solution of this utility model is as follows:
[0024] like Figure 1 - Figure 4As shown, the compact high-temperature preheating and welding collaborative mechanical system includes a base 1. Two symmetrically arranged handles 2 are fixedly connected to the left side wall of the base 1. A placement platform 3 is fixedly connected to the left side wall of the base 1. A fixing plate 4 is hinged to the upper surface of the base 1. Two symmetrically arranged support columns 5 are fixedly connected to the upper surface of the fixing plate 4. A first connecting plate 6 is fixedly connected to the front side wall of each of the two support columns 5. The same stop bar 7 is fixedly connected to the other end of each of the two first connecting plates 6. The same connecting block 8 is fixedly connected to the upper surface of the two support columns 5. A moving device is provided on the upper surface of the fixing plate 4. A preheating welding device is provided on the front side wall of the connecting block 8. A limit device is provided on the upper surface of the connecting block 8.
[0025] Furthermore, the moving device includes a guide rail 9, which is fixedly connected to the upper surface of the fixed plate 4. A welding table 10 is slidably connected to the surface of the guide rail 9. Two support frames 11 are fixedly connected to the upper surface of the fixed plate 4. A hydraulic rod 12 is fixedly connected between the two support frames 11. A first connecting piece 13 is fixedly connected to the output end of the hydraulic rod 12. The first connecting piece 13 is fixedly connected to the lower surface of the welding table 10. Through the linkage design of the guide rail 9 and the hydraulic rod 12, the precise linear movement of the welding table 10 is achieved. This ensures the accuracy of the welding position and provides a stable thrust through the hydraulic system, avoiding errors caused by traditional manual adjustment and significantly improving the repeatability and efficiency of welding operations.
[0026] Furthermore, the preheating welding device includes a fixed block 14, which is fixedly connected to the front side wall of the connecting block 8. A square block 15 is fixedly connected to the front side wall of the fixed block 14. Two symmetrically arranged limiting rods 16 are slidably connected to the inner wall of the square block 15. The upper ends of the two limiting rods 16 are fixedly connected to the same strip plate 17. An electric push rod 18 is fixedly connected to the front side wall of the fixed block 14. The output end of the electric push rod 18 is fixedly connected to the upper surface of the strip plate 17. The lower ends of the two limiting rods 16 are fixedly connected to the same adjuster 19. A preheater 20 is fixedly connected to the lower surface of the adjuster 19. A welding head 21 is fixedly connected to the lower surface of the preheater 20. The structure of using the electric push rod 18 to drive the limiting rods 16, combined with the adjustable preheater 20, achieves precise control of the height and pressure of the welding head 21. This can improve the welding quality through preheating and avoid workpiece deformation due to overpressure.
[0027] Furthermore, the limiting device includes a hollow block 22, which is fixedly connected to the upper surface of the connecting block 8. Four cylinders 23 are fixedly connected to the lower surface of the hollow block 22, and the lower ends of the four cylinders 23 are fixedly connected to the same partition 24. A second connecting member 25 is provided on the inner wall of the hollow block 22. The frame structure formed by the hollow block 22 and the cylinders 23 provides a stable support foundation for the preheating welding device. The design of the partition 24 effectively isolates welding spatter.
[0028] Furthermore, two symmetrically arranged second connecting plates 26 are fixedly connected to the two side walls of the preheater 20. The other end of the two second connecting plates 26 is fixedly connected to the second connecting piece 25. The symmetrical fixing method of the two-sided second connecting plates 26 makes the force distribution of the preheater 20 more uniform. This not only eliminates the risk of off-center load caused by single-point connection, but also reduces the vibration transmission during the welding process through rigid connection, further ensuring the working stability of the welding head 21.
[0029] Furthermore, a protective cover 27 is fixedly connected to the rear side wall of the hollow block 22. The protective cover 27 is made of stainless steel. The stainless steel protective cover 27 not only provides physical protection against dust and splashes for the internal connecting parts, but its corrosion resistance also adapts to the high temperature and dusty working conditions of the welding environment, which greatly reduces the frequency of equipment maintenance and extends the service life of the core components.
[0030] Working principle: The operator moves the equipment to the working position via handle 2, places the workpiece on the welding table 10, and the hydraulic rod 12 is in its initial retracted state. The welding table 10 is located at the starting end of the guide rail 9. The preheater 20 and the welding head 21 are raised to a safe height via the electric push rod 18. The hydraulic rod 12 extends, pushing the welding table 10 along the guide rail 9 towards the welding head 21 until the workpiece reaches the preheating position. The electric push rod 18 is activated, driving the strip plate 17 to descend. The limit rod 16 guides the adjuster 19 to move smoothly downward, bringing the preheater 20 close to the workpiece surface. The preheater 20 is activated, uniformly heating the welding area, reducing the thermal stress and brittleness of the material, and preparing for subsequent welding. After preheating, the electric push rod 18 descends further, causing the welding head 21 to contact the workpiece welding point. The welding head 21 is activated, and the welding operation begins. The preheater 20 remains operational to maintain temperature stability in the welding area. The second connecting plate 26 and the second connecting piece 25 work together to ensure that the preheater 20 and the welding head 21 remain stable during operation, preventing shaking that could affect welding accuracy. During welding, the hydraulic rod 12 can precisely control the moving speed and direction of the welding table 10 according to the welding trajectory, enabling the processing of complex welds. The second connecting piece 25 inside the hollow block 22 cooperates with the cylinder 23 and the partition 24 to provide auxiliary support for the preheater 20, enhancing the rigidity of the overall structure.

Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of this invention.
