Description

Technical Field

[0001] This utility model relates to the field of turbine partition welding technology, specifically to automatic welding auxiliary equipment for turbine partition anti-deformation. Background Technology

[0002] During the processing of turbine diaphragms, welding is required. However, stress can easily increase during welding, leading to diaphragm deformation. Therefore, auxiliary equipment is needed to effectively position the diaphragms and ensure a stable weld. For example, patent document CN221695849U discloses a method that uses a sliding slide and clamping plate to adjust the distance between the diaphragm bands and effectively fix their position. This tooling allows the diaphragm bands to be welded to blades of different lengths, ensuring the stability of the diaphragm bands during welding and preventing deformation due to stress. This ensures the quality and efficiency of diaphragm blade welding.

[0003] However, when the above-mentioned equipment clamps and positions the partition, the external structure of the equipment is fixed and can only be adapted to partitions of fixed size. When welding partitions of different sizes is required, it cannot stably position the partition, which reduces the auxiliary effect of welding the partition. Summary of the Invention

[0023] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0024] This utility model discloses an automatic welding auxiliary device for preventing deformation of steam turbine diaphragms.

[0025] This utility model provides, for example Figure 1-3 The turbine diaphragm anti-deformation automatic welding auxiliary equipment shown includes a mounting plate 1. A plurality of first elastic telescopic rods 2 are fixedly arranged at intervals on one side of the upper surface of the mounting plate 1. The first elastic telescopic rods 2 are arranged in an L shape. Two symmetrically arranged support blocks 3 are provided on the other side of the upper surface of the mounting plate 1. A synchronous adjustment mechanism is provided between the two support blocks 3. The synchronous adjustment mechanism is used to drive the two support blocks 3 to move synchronously. The synchronous adjustment mechanism includes two symmetrically arranged lead screws 9. A sliding groove is opened on the upper surface of the mounting plate 1. The two lead screws 9 are respectively rotatably arranged on both sides of the inner wall of the sliding groove and are fixedly connected. The two support blocks 3 are respectively threaded on the outside of the two lead screws 9 and slidably arranged in the sliding groove. A groove is opened on the upper surface of the mounting plate 1. The end of the lead screw 9 passes through the groove and is fixedly provided with a rotating block 10.

[0026] A support plate 4 is fixedly installed in the middle of the upper surface of the mounting plate 1. An electric push rod 5 is fixedly installed on the top of the support plate 4. A mounting block 6 is fixedly installed on the top of the electric push rod 5. A vertical rod 7 is fixedly installed at the middle of the top of the mounting block 6.

[0027] When using this turbine diaphragm anti-deformation automatic welding auxiliary equipment, firstly, according to the outer diameter of the diaphragm to be welded, the distance between the two support blocks 3 is adjusted through the synchronous adjustment mechanism. Specifically, the rotating block 10 is rotated, which drives the lead screw 9 to rotate. Since the two lead screws 9 are fixedly connected and symmetrically arranged, the two support blocks 3 will slide synchronously inward or outward along the slide groove under the drive of the lead screw 9. When the support blocks 3 move to the appropriate position, the diaphragm is placed on the first elastic telescopic rod 2 and the support block 3. At this time, the first elastic telescopic rod 2 can play a preliminary supporting and buffering role, and its L-shaped structure can better fit the shape of the diaphragm, preventing the diaphragm from shifting during placement.

[0028] In order to provide stable multi-point support for the inner wall of the partition according to its inner diameter, and to further improve the positioning and clamping effect of the partition, such as... Figure 1-2 As shown, the mounting block 6 has second elastic telescopic rods 8 on both sides. A synchronous pushing mechanism is provided between the vertical rod 7 and the second elastic telescopic rods 8. The synchronous pushing mechanism includes a threaded tube 11. The wall of the vertical rod 7 is threaded and threaded inside the threaded tube 11. A push plate 12 is fixedly sleeved on the outer wall of the threaded tube 11. U-shaped plates 13 are fixedly installed on both sides of the push plate 12. A support rod 14 is fixedly installed inside the mounting block 6. The two second elastic telescopic rods 8 are staggered and rotatably sleeved on the outside of the support rod 14. Torsion springs 15 are sleeved on both ends of the support rod 14. The two ends of the torsion springs 15 are fixedly connected to the support rod 14 and the second elastic telescopic rods 8 respectively. The U-shaped plates 13 are sleeved on the outside of the second elastic telescopic rods 8. Push blocks 16 are fixedly installed at the ends of the vertical rod 7 and the two second elastic telescopic rods 8.

[0029] Next, based on the inner diameter of the partition, the electric push rod 5 is activated. The electric push rod 5 pushes the mounting block 6 up or down, and the mounting block 6 drives the vertical rod 7 to move. The vertical rod 7 is threadedly engaged with the threaded tube 11. The movement of the vertical rod 7 will cause the threaded tube 11 to rotate. When the threaded tube 11 rotates, the push plate 12 fixed on its outer wall will rotate accordingly. The U-shaped plates 13 on both sides of the push plate 12 will also rotate synchronously. The U-shaped plates 13 are fitted outside the second elastic telescopic rod 8. The rotation of the U-shaped plates 13 will push the second elastic telescopic rod 8 to rotate around the support rod 14. Due to the action of the torsion spring 15, the second elastic telescopic rod 8 will be subject to a certain resistance when rotating, and it can also remain stable after being adjusted to the position. When the push block 16 at the end of the vertical rod 7 and the second elastic telescopic rod 8 contacts the inner wall of the partition and provides stable support, the action of the electric push rod 5 is stopped. At this time, the partition is stably clamped between the first elastic telescopic rod 2, the support block 3 and the push block 16, which can effectively prevent the partition from deforming during the welding process.

[0030] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
