For those of ordinary skill in the art, the specific meanings of the above terms in this application can be understood according to specific situations.
[0028] Regarding the welding process of the seal ring, usually the inner ring of the seal ring is welded first, and then the outer ring of the seal ring is welded. However, it is difficult to ensure the coaxiality between multiple seal ring groups during the welding process of the outer rings of existing multi - stacked seal rings, and it is also necessary to prevent the seal ring thin plates from deforming. Based on this, this embodiment provides an outer - ring welding fixture for the seal ring.
[0029] As Figure 1As shown, an embodiment of the present invention provides a sealing ring outer ring welding fixture, which is used for welding between adjacent sealing ring groups. Each sealing ring group includes a first sealing ring 100 and a second sealing ring 200. The inner rings of the first sealing ring 100 and the second sealing ring 200 are fixedly connected, preferably welded; a gap is formed between the first sealing ring 100 and the second sealing ring 200 from the inner ring to the outer ring of the sealing ring.
[0030] The clamp includes a support seat 300, an anti-deformation component 400 and a clamping fixture 500. At least two sealing ring groups are arranged between the support seat 300 and the clamping fixture 500. The supporting surface of the support seat 300 matches the shape of the first sealing ring 100 and can be tightly connected to the first sealing ring 100; the anti-deformation component 400 is arranged in the gap between the first sealing ring 100 and the second sealing ring 200, and the clamping fixture 500 is arranged at the top of the topmost sealing ring group.
[0031] The supporting surface of the support seat 300 of the utility model can be tightly connected with the sealing ring, the anti-deformation component 400 is arranged between the two sealing rings to prevent the sealing rings from deforming, and the clamping fixture 500 uses its own gravity to achieve clamping. Through the mutual cooperation of the support seat 300, the anti-deformation component 400 and the clamping fixture 500, the sealing ring sheet is accurately positioned and firmly fixed, effectively preventing the problem of reduced welding quality caused by position displacement or shaking of the sealing ring, and at the same time providing necessary support and stability during the welding process, reducing vibration and deformation during the welding process, helping to maintain the flatness and consistency of the welding interface, and further improving the welding quality and yield rate.
[0032] In some embodiments of the present invention, outer edges of the first sealing ring 100 and the second sealing ring 200 protrude beyond outer edges of the anti-deformation component 400 and the clamping fixture 500 to improve the sealing welding effect.
[0033] Optionally, the clamping fixture 500 matches the shape of the second sealing ring 200 and can be tightly connected to the second sealing ring 200 .
[0034] It can be understood that the anti-deformation component 400 and the clamping fixture 500 are matched with the shapes and sizes of the first sealing ring 100 and the second sealing ring 200 respectively, so as to achieve precise support and positioning of the sealing rings, thereby improving the practicality and versatility of the clamp; and considering that the sealing ring itself has a small weight, the sealing ring can be clamped by relying on the self-gravity of the support base 300 and the clamping fixture 500, without the need to add a special clamping device. The structure is simple and easy to use, which can effectively improve the welding efficiency.
[0035] In some embodiments of the present utility model, the anti-deformation component 400 is composed of several blocks 410, and the total outer perimeter of the blocks 410 is less than or equal to the outer perimeter of the sealing ring, so as to avoid affecting the welding process of the anti-deformation component 400.
[0036] Optionally, the several blocks 410 are connected end to end, or the several blocks 410 are distributed at intervals in the gap between the first sealing ring 100 and the second sealing ring 200. There is no special limitation on this, as long as the purpose of preventing the deformation of the sealing ring during the welding process can be achieved.
[0037] It can be understood that by adding a plurality of blocks 410 in the gap between the first sealing ring 100 and the second sealing ring 200, the present utility model can reduce the vibration and deformation of the sealing ring sheet during the welding process, so as to ensure the flatness and consistency of the welding interface, and improve the welding quality and the finished product rate.
[0038] In some embodiments of the present utility model, the support seat 300 includes a base 310 and an extension portion 320 provided on one side of the base 310. The base 310 is matched with the shape of the first sealing ring 100, and the first sealing ring 100, the second sealing ring 200 and the clamping and fixing member 500 can all be sleeved on the extension portion 320.
[0039] It can be understood that the support seat 300 is closely attached to the first sealing ring 100, and the cooperation between the support seat 300 and the clamping and fixing member 500 can provide a clamping force to the sealing ring to prevent the problem of the decline of the welding quality caused by the position deviation or shaking during the welding process; the length of the extension portion 320 can be adjusted according to the actual situation to realize the welding of multiple sealing ring combinations.
[0040] The working process of the welding fixture for the outer ring of the sealing ring of the present utility model is as follows:
[0041] (1) Place the anti-deformation component 400 composed of several blocks 410 in the gap formed by the first sealing ring 100 and the second sealing ring 200 to prevent the problem of the deformation of the sealing ring sheet during the clamping process. This operation needs to be carried out for each sealing ring group;
[0042] (2) Place the first sealing ring group on the support seat 300 so that the first sealing ring 100 therein is closely attached to the support seat 300 to achieve positioning;
[0043] (3) Place the second sealing ring group on the first sealing ring group, and place the clamping and fixing member 500 on the top of the second sealing ring group, and rely on the gravity of the clamping and fixing member 500 to achieve clamping and carry out welding;
[0044] (4) After the welding of the first weld seam is completed, remove the clamping and fixing member 500, and repeat steps (1)-(3) until the welding between multiple sealing ring groups is completed.
[0045] In summary, the utility model effectively improves the efficiency and portability of welding operations. Moreover, due to the precise positioning function of the fixture, the operator can quickly complete the assembly and positioning of the sealing ring without cumbersome manual adjustment, greatly shortening the preparation work before welding and improving work efficiency.
[0046] The above are only the preferred embodiments of the utility model. It should be noted that for those of ordinary skill in the art, without departing from the technical principle of the utility model, several improvements and substitutions can be made, and these improvements and substitutions should also be regarded as the protection scope of the utility model.
