Description

Technical Field

[0001] This utility model relates to the field of valve processing technology, and more specifically, to a rapid welding equipment for valve fittings. Background Technology

[0002] In the field of pipeline system installation and maintenance, the connection quality of valves and pipe fittings directly affects the system's sealing performance, pressure resistance, and service life. Welding, as a key process for achieving a permanent connection between the two, has always been a focus of industry attention in terms of efficiency and precision.

[0003] Traditional valve and pipe fitting welding relies heavily on manual operation. Operators must hold welding tools and adjust the welding angle and distance based on experience, while manually fixing the workpiece to be welded. This method has significant limitations: First, manual fixing makes it difficult to guarantee the absolute coaxiality and positional stability of the valve and fitting during the welding process. Slight workpiece movement can easily lead to weld misalignment and uneven penetration, affecting connection strength and sealing performance. Second, the welding angle and distance are entirely controlled manually, resulting in poor consistency, especially in mass production, leading to significant fluctuations in product quality.

[0004] With the increasing automation in manufacturing, some simple welding auxiliary equipment has emerged. However, most of these devices are single-function, only capable of fixing the workpiece or roughly adjusting the welding position. They cannot meet the comprehensive needs of precise positioning, multi-angle welding, and safety protection, making them unsuitable for welding scenarios involving valves and pipe fittings of different specifications, thus hindering further improvements in pipeline system construction efficiency. Therefore, developing an automated welding equipment that integrates precise workpiece fixing, flexible welding angle adjustment, safety protection, and efficient operation has become key to solving the pain points of traditional welding processes. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a rapid welding equipment for valves and pipe fittings that can overcome or at least partially solve the above problems.

[0006] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by this utility model is: a rapid welding equipment for valves and pipe fittings, including a welding box, a welding plate fixedly connected to the welding box, a welding head rotatably connected to the welding plate, pipe fitting clamps symmetrically slidably connected to the welding head, a telescopic column fixedly connected to the welding box, a connecting plate fixedly connected to the telescopic column, a movable plate slidably connected to the connecting plate, and a welding gun fixedly connected to the movable plate.

[0007] The welding box is fixedly connected to support feet for supporting the welding box.

[0008] A sliding rod is fixedly connected to the welding box, and splash guards are symmetrically slidably connected to the sliding rod.

[0009] The movable plate slides on the connecting plate, allowing for angle adjustment of the welding gun.

[0010] The telescopic column is positioned at the center of two sets of symmetrical pipe clamps.

[0011] During welding, the telescopic column is a crucial component for adjusting the welding torch position. Positioned at the center of two sets of symmetrical pipe clamps, it extends and retracts, moving the connecting plate, movable plate, and welding torch vertically. This allows the welding torch to quickly approach or move away from the welding area, adapting to varying welding distance requirements. Simultaneously, the movable plate slides on the connecting plate, a design used for angle adjustment of the welding torch. Operators can adjust the sliding position of the movable plate on the connecting plate according to the required welding angle, thereby changing the tilt angle of the welding torch to ensure optimal alignment with the weld seam, guaranteeing welding precision and quality.

[0012] By adopting the above technical solution, this utility model has the following beneficial effects compared with the prior art:

[0013] 1. This utility model achieves precise clamping of valves and pipe fittings by using symmetrically sliding pipe clamps on the welding head, ensuring the coaxiality and positional stability of the workpiece during welding, avoiding problems such as weld seam offset and uneven penetration caused by manual fixing. At the same time, the cooperative design of the telescopic column and the movable plate can precisely adjust the distance and angle of the welding gun to ensure weld seam consistency. It is especially suitable for mass production scenarios and greatly reduces product quality fluctuations.

[0014] 2. This utility model reduces the time cost of manual adjustment through automated structural design: the rotation function of the welding head can quickly switch the welding position, and the lifting of the telescopic column and the sliding of the movable plate realize the rapid positioning of the welding gun without the need for repeated manual calibration. Compared with traditional manual welding, the equipment can significantly shorten the welding cycle of a single workpiece and improve the overall work efficiency.

[0015] 3. This utility model uses a splash guard on the welding box to open and close flexibly via a sliding rod, forming a closed protective space during welding, effectively blocking sparks and molten slag from splashing. This not only protects operators from high-temperature burns but also avoids damage to surrounding equipment. The stable support design of the support feet reduces vibration interference during equipment operation and improves the reliability of operation in complex industrial environments.

[0022] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model, but are not intended to limit the scope of this utility model.

[0023] Example: Refer to Figures 1-3 A rapid welding device for valves and pipe fittings includes a welding box 1, a welding plate 5 fixedly connected to the welding box 1, a welding head 51 rotatably connected to the welding plate 5, pipe fitting clamps 52 symmetrically slidably connected to the welding head 51, a telescopic column 6 fixedly connected to the welding box 1, a connecting plate 61 fixedly connected to the telescopic column 6, a movable plate 62 slidably connected to the connecting plate 61, and a welding gun 63 fixedly connected to the movable plate 62.

[0024] The welding box 1 is fixedly connected to a support foot 2 for supporting the welding box 1.

[0025] A sliding rod 3 is fixedly connected to the welding box 1, and a splash guard 4 is symmetrically slidably connected to the sliding rod 3.

[0026] The movable plate 62 is slidably connected to the connecting plate 61 and is used for angle adjustment of the welding gun 63.

[0027] The telescopic column 6 is positioned at the center of the two sets of symmetrical pipe clamps 52.

[0028] During welding, the telescopic column 6 is a crucial component for adjusting the position of the welding gun 63. Located at the center of the two sets of symmetrical pipe clamps 52, it can extend and retract, causing the connecting plate 61, the movable plate 62, and the welding gun 63 to move vertically as a whole. This allows the welding gun 63 to quickly approach or move away from the welding area, adapting to different welding distance requirements. Simultaneously, the movable plate 62 can slide on the connecting plate 61. This design allows for angle adjustment of the welding gun 63. The operator can adjust the sliding position of the movable plate 62 on the connecting plate 61 according to the required welding angle, thereby changing the tilt angle of the welding gun 63. This ensures that the welding gun 63 is aligned with the weld seam at the optimal angle, guaranteeing welding accuracy and quality.

[0029] This utility model uses a support base consisting of a welding box 1 and support feet 2. The support feet 2 provide stable support for the welding box 1, so that the entire equipment remains stable during operation and avoids affecting the welding accuracy due to shaking.

[0030] During the welding preparation stage, the slide bar 3 on the welding box 1 plays a role. The splash guard 4, which is symmetrically connected to the slide bar 3, can slide open to both sides, making it convenient for operators to place and adjust the pipe fittings. When the welding operation is in progress, the splash guard 4 can be closed to form a protective barrier to prevent sparks and slag generated during the welding process from splashing everywhere, which not only ensures the safety of operators, but also avoids damage to the surrounding environment and equipment.

[0031] Fixing the pipe fittings is a key prerequisite for welding. The welding head 51, which is rotatably connected to the welding plate 5, and the pipe fitting clamp 52, which is symmetrically slidably connected to the welding head 51, can be adjusted according to the size and shape of the valve and pipe fittings to firmly clamp and fix the valve and pipe fittings to be welded, ensuring that the position of the two is stable during welding, laying the foundation for precise welding. In addition, the rotation function of the welding head 51 can flexibly adjust the orientation of the welding part, making it convenient for the welding gun 63 to perform welding operations from a suitable angle.

[0032] During welding, the telescopic column 6 is a crucial component for adjusting the position of the welding gun 63. Located at the center of the two sets of symmetrical pipe clamps 52, it can extend and retract, causing the connecting plate 61, the movable plate 62, and the welding gun 63 to move vertically as a whole. This allows the welding gun 63 to quickly approach or move away from the welding area, adapting to different welding distance requirements. Simultaneously, the movable plate 62 can slide on the connecting plate 61. This design allows for angle adjustment of the welding gun 63. The operator can adjust the sliding position of the movable plate 62 on the connecting plate 61 according to the required welding angle, thereby changing the tilt angle of the welding gun 63. This ensures that the welding gun 63 is aligned with the weld seam at the optimal angle, guaranteeing welding accuracy and quality.

[0033] Once all preparations are complete, the welding gun 63 is activated. With the cooperation of the telescopic column 6, connecting plate 61, and movable plate 62, it precisely aligns with the welding points of the valve and fitting to perform the welding operation, achieving a rapid and high-quality connection between the valve and fitting. Throughout the process, each component performs its function and works collaboratively, realizing the automation and high efficiency of valve and fitting welding.
