Description

Technical Field

[0001] This utility model relates to the field of welding tooling technology, and more specifically, to a welding tooling for a windshield ring. Background Technology

[0002] In the manufacturing process of fans and ventilation equipment, the air shroud is a key component, and its quality directly affects the performance and service life of the fan. For example... Figure 5 As shown, the wind shield typically consists of a fixed body and a fan cover, and the welding quality of both is particularly important. However, existing wind shield welding methods have many problems.

[0003] Traditional welding methods often rely on manual operation, requiring workers to manually align the fan cover with the fixed body at the welding points before welding. This method is not only inefficient, but also, due to the limitations of manual operation, it is difficult to guarantee the positional accuracy of the fan cover and the fixed body each time, resulting in inconsistent weld quality. In actual use, inaccurate welding positions may affect the airflow guidance of the fan, reduce the fan's working efficiency, and may even cause safety hazards.

[0004] Furthermore, the method of fixing the fan cover to the fixed body during the welding process is not ideal. The existing fixing method may not provide sufficient stability, causing components to easily shift during welding, further affecting the welding quality. Moreover, the existing fixing method may require a lot of time and effort to adjust and fix, increasing the production cycle and cost.

[0005] As the wind turbine manufacturing industry continues to demand higher product quality and production efficiency, developing a welding fixture that can improve the welding precision of the wind shield, enhance the stability of the welding process, and increase production efficiency is of significant practical importance. It can not only ensure the performance and quality of the wind turbine but also effectively reduce production costs and improve the company's market competitiveness. Utility Model Content

[0006] Based on the above-mentioned technical problems, this utility model proposes a welding fixture for windproof rings.

[0007] A welding fixture for a windshield ring includes: The workbench is equipped with multiple sets of mounting holes; Windproof ring: The fixed body is a box-shaped body, which is fixed on the workbench by a positioning mechanism. A welding hole is provided at one end, and a centrifugal support mechanism is provided on the workbench below the welding hole. The fan cover is installed at the welding hole and matches the shape and size of the welding hole. Positioning mechanism: At least two positioning blocks are fixed to the worktable by positioning pins and mounting holes. The positioning blocks are provided with bidirectional limiting surfaces to engage with the right-angled edges of the main body. Centrifugal support mechanism: The top support platform is fixed to the workbench, and the top support platform is equipped with radial sliding grooves; A rotary cylinder drives a rotating disk to rotate. The slider is embedded in the groove, and the slider has an arc-shaped long groove. One end of the sliding shaft is connected to the rotating disk, and the other end is equipped with a rotatable bearing that fits into a long groove; The rotating disk rotates and pushes the slider to move radially along the slide groove through the sliding shaft and bearing. The outward movement of the slider can support the fan cover and make it fit tightly with the welding holes of the fixed body.

[0008] The fixed body is mounted on the worktable using a positioning mechanism. The worktable is provided with at least two positioning blocks, each of which is locked at a right angle to limit the fixed body in both directions. Furthermore, the positioning mechanism also includes a quick clamp, which is installed on the mounting hole on the outside of the fixing body, and the quick clamp can be manually clamped to the side of the outside of the fixing body; Furthermore, the limiting surface of the positioning block is right-angled, and the two limiting surfaces are locked on the outside of the right-angled edge of the fixing body; Furthermore, the top support platform is provided with multiple centrally symmetrical fixing blocks, and there are grooves between the fixing blocks. The slider is slidably installed in the grooves between the fixing blocks. The outer side of the fixing block and the outer end face of the slider are arc-shaped surfaces that match the fan cover.

[0009] Furthermore, the top support platform is installed on the workbench by engaging multiple positioning pins and mounting holes.

[0010] Beneficial effects: 1. Improve welding accuracy: The precise positioning of the fixed body by the positioning mechanism and the precise opening and positioning of the fan cover by the centrifugal support mechanism ensure the positional accuracy of the fixed body and the fan cover during welding, effectively avoiding welding quality problems caused by positional deviation, improving the welding accuracy of the wind shield, and ensuring that the welded wind shield can meet the performance requirements of the fan. 2. Enhanced welding stability: The multiple fixation of the fixed body by the positioning block, positioning pin, and quick clamp, as well as the stable support of the fan cover by the centrifugal support mechanism, ensure that the fixed body and the fan cover remain stable during the welding process and are not prone to displacement. This greatly enhances the stability of the welding process, which is conducive to improving welding quality and reducing welding defects. 3. Improve production efficiency: The automated jacking action of the centrifugal jacking mechanism reduces the time for manual adjustment and fixing, improves the degree of automation in the production process, and thus effectively improves production efficiency and reduces production costs; 4. High adaptability: The arc-shaped surface design of the slider and fixed block in the centrifugal support mechanism can better adapt to the circular shape of the fan cover, and can achieve good support and positioning effect for fan covers of different specifications, enhancing the versatility and adaptability of the tooling.

Detailed Implementation

[0012] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0013] like Figures 1-5 The welding fixture shown is mainly composed of a workbench 1, a wind shield ring, a positioning mechanism, and a centrifugal support mechanism 7. The various parts work together to ensure the smooth progress of the wind shield ring welding operation.

[0014] The workbench 1 serves as a basic support component and is equipped with multiple sets of mounting holes 5. The mounting holes 5 can be arranged in an array. The mounting holes 5 provide a connection base for the installation of the positioning mechanism, centrifugal support mechanism 7, and quick clamp 6, ensuring that the installation position of each component is accurate and stable, and creating a stable working platform for the welding of the wind shield ring.

[0015] The wind shield is made by welding the fixed body 2 and the fan cover 3.

[0016] Fixed body 2: It is a box structure with an open lower side, which is the main support part of the wind shield ring. It is fixed on the workbench 1 by a positioning mechanism to ensure stable position during welding. One end is provided with a welding hole 8 for welding connection with the fan cover 3. The shape and size of the welding hole 8 match the fan cover 3, providing a prerequisite for precise welding between the two. The workbench 1 below the welding hole 8 is provided with a centrifugal support mechanism 7 for supporting the fan cover 3 and making it fit tightly with the welding hole 8.

[0017] Fan cover 3: Located at welding hole 8, matching the shape and size of welding hole 8 to ensure accurate connection during welding, thus guaranteeing the function of the wind shield ring.

[0018] like Figure 1 and Figure 4 As shown, both the welding hole 8 and the fan cover 3 are circular, and the welding hole 8 has different heights in the vertical direction. In order to ensure full welding between the fan cover 3 and the fixed body 2, the thickness of the fan cover 3 is also different. exist Figures 4-5 In the middle, the welding hole 8 extends beyond the structure of the fixed body 2. In order to ensure the full welding between the fan cover 3 and the fixed body 2, an integrated arc plate 201 is added to the welding hole 8 at the fixed body 2.

[0019] The positioning mechanism includes positioning block 4 and quick clamp 6.

[0020] Positioning block 4 and positioning pin: At least two positioning blocks 4 are fixed to the worktable 1 by positioning pins and mounting holes 5, such as Figure 1 As shown, two positioning blocks 4 are symmetrically positioned at the two right angles of the fixed body 2. The positioning blocks 4 have bidirectional limiting surfaces and are in the shape of right angles. The two limiting surfaces are locked on the outside of the right angle edge of the fixed body 2, which limits the movement of the fixed body 2 in the horizontal direction and ensures that the fixed body 2 is accurately positioned on the worktable 1, laying the foundation for subsequent welding.

[0021] Quick clamp 6: Installed on the mounting hole 5 on the outside of the fixed body 2, it can be manually operated to clamp the side of the fixed body 2. Based on the positioning block 4 limit, it further reinforces the fixed body 2 from other sides, preventing the fixed body 2 from shifting due to welding stress during the welding process, enhancing the fixing effect and ensuring the welding quality.

[0022] The centrifugal support mechanism 7 includes a support platform 702, a rotary cylinder 701, a slider 704, and a rotating disk 711.

[0023] Top support platform 702: Fixed to the workbench 1, providing an installation base for other components of the centrifugal top support mechanism 7. The top support platform 702 has radially arranged grooves 703 to accommodate the slider 704 and guide its movement. Multiple centrally symmetrical fixing blocks 707 are provided on the top support platform 702, forming grooves 703 between the fixing blocks 707. The slider 704 is slidably installed within the grooves 703 between the fixing blocks 707. The outer surfaces of the fixing blocks 707 and the outer end faces of the slider 704 are arc-shaped surfaces that match the fan cover 3, allowing for better fit to the surface of the fan cover 3, improving the top support effect and adaptability. Meanwhile, as... Figure 2 As shown, the fixing block 707 is provided with positioning holes 708, which correspond one-to-one with the mounting holes 5. The top support platform 702 is installed on the workbench 1 by multiple positioning pins in cooperation with the mounting holes 5, ensuring that the top support platform 702 is installed firmly and providing reliable support for the top support operation.

[0024] like Figures 2-3 As shown, four fixed blocks 707 and sliders 704 are provided on the top support platform 702. The fixed blocks 707 are located at the four corners of the top support platform 702, and the sliders 704 are located in the grooves 703 between the fixed blocks 707. The four sliders 704 can slide synchronously in four directions (up, down, left, and right) to support the fan cover 3.

[0025] Rotary cylinder 701 and rotating disk 711: Rotary cylinder 701 drives rotating disk 711 to rotate, and is the power source for centrifugal support mechanism 7, such as... Figures 2-3 As shown, the center of the rotating disk 711 is provided with a connecting cylinder 712 that is fixedly connected to the output shaft 710 of the rotating cylinder 701. When the rotating cylinder 701 is working, it drives the rotating disk 711 to make a circular motion, providing power for the movement of the slider 704.

[0026] Slider 704, sliding shaft 705 and bearing 706: Slider 704 is embedded in sliding groove 703 and can move radially along sliding groove 703. Slider 704 has an arc-shaped long groove 709. One end of sliding shaft 705 is connected to rotating disk 711, and the other end is provided with a rotatable bearing 706 that fits into long groove 709. When rotating disk 711 rotates, sliding shaft 705 moves in a circular motion with rotating disk 711. Since bearing 706 can rotate in long groove 709 of slider 704, the cooperation between sliding shaft 705 and bearing 706 will push slider 704 to move radially along sliding groove 703 synchronously. When slider 704 moves outward, it can support fan cover 3 externally, so that it fits tightly with welding hole position 8 of fixed body 2, providing good docking conditions for welding operation. When slider 704 moves inward, it is convenient to place and remove fan cover 3.

[0027] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
