[0001] The utility model relates to the technical field of sealing ring welding, in particular to a clamp used for sealing ring welding. Background Art

[0002] At present, there is a lack of professional fixtures for welding the inner ring of the sealing ring. Due to the lack of special fixtures, it is difficult to achieve accurate positioning and stable fixation of the sealing ring during the welding process, which directly leads to unstable welding quality and reduced yield rate. The unstable welding quality will not only affect the sealing performance and service life of the sealing ring, but also increase the defective rate and rework rate in the production process, thereby increasing production costs.

[0003] Therefore, how to provide a clamp for sealing ring welding to improve the positioning accuracy and stability of the sealing ring during the welding process is a problem that technical personnel in this field urgently need to solve. Utility Model Content

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of this application, unless otherwise specified, "plurality" means two or more.

[0028] In the description of this application, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0029] like Figures 1 to 3 As shown, an embodiment of the utility model provides a clamp for welding sealing rings, wherein the sealing rings include a first sealing ring 210 and a second sealing ring 220, and the clamp is used for welding between the inner ring of the first sealing ring 210 and the inner ring of the second sealing ring 220, wherein the sealing rings can be in any shape available on the market, such as O-shaped, U-shaped, W-shaped, etc., without any special limitation.

[0030] In some embodiments of the present invention, the clamp includes a support seat 100 and a positioning block. The top of the support seat 100 is provided with a groove 110 matching the sealing ring, and the first sealing ring 210 is located in the groove 110 .

[0031] Furthermore, the positioning block includes a first positioning block 310 and a second positioning block 320 which are sequentially arranged on the top of the first sealing ring 210, the second sealing ring 220 is located between the first positioning block 310 and the second positioning block 320, and the shape of the first positioning block 310 can be adapted to the shape of the sealing ring; preferably, the bottom shape of the first positioning block 310 is adapted to the shape of the first sealing ring 210, and the top shape is adapted to the shape of the second sealing ring 220.

[0032] It should be noted that the shape of the first positioning block 310 can be adapted to the shape of the sealing ring. When the sealing ring is a curved rigid or elastic material with a variable curvature, the shape of the groove 110 and the first positioning block 310 also need to be a curved cross-section with a variable curvature, and be consistent with the shape of the first positioning block 310 to achieve precise positioning; and when the sealing ring is a planar elastic material, under the action of pressure, through the action of the first positioning block 310 and the groove 110, the sealing ring can be deformed to adapt to the shape of the first positioning block 310 and the groove 110, thereby achieving precise positioning.

[0033] It can be understood that the support seat 100 plays a key supporting role as a stable base of the entire clamp. The first sealing ring 210 is accurately positioned and firmly fixed by the groove 110 of the support seat 100 and the first positioning block 310, and the second sealing ring 220 is accurately positioned and firmly fixed by the first positioning block 310 and the second positioning block 320, which effectively prevents the problem of reduced welding quality caused by position displacement or shaking of the sealing ring. At the same time, the support seat 100 and the positioning block provide necessary support and stability during the welding process, reduce vibration and deformation during the welding process, help maintain the flatness and consistency of the welding interface, and further improve the welding quality and yield rate.

[0034] In some embodiments of the utility model, the thickness of the first positioning block 310 decreases along a first direction, and the first direction is the first positioning block 310 from outside to inside along its radial direction; since the second positioning block 320 mainly plays a stabilizing role, the shape of the second positioning block 320 is not specially limited, and it can be the same shape as the first positioning block 310 or a planar structure or other shapes. Preferably, the side of the second positioning block 320 that contacts the second sealing ring 210 has a shape that matches the shape of the second sealing ring 210, and the side that does not contact the second sealing ring 210 is in any shape such as a plane or a curved surface.

[0035] It is understandable that, since the clamp of the present invention is for welding between the inner circles of two sealing rings, it is necessary to ensure that the distance between the inner circles of the two sealing rings is small enough, and the first positioning block 310 is set to decrease in thickness along its radial direction, which can ensure that the distance between the first sealing ring 210 and the second sealing ring 220 decreases from outside to inside along the radial direction until the first sealing ring 210 and the inner circle of the second sealing ring 220 are closely close to each other. Such a setting can not only make the welding process easier and ensure the flatness of the welding interface, but also because the closer to the outer edge the distance between the first sealing ring 210 and the second sealing ring 220 is, the larger the distance is and the first positioning block 310 is spaced between the opposite surfaces of the two sealing rings, so the flatness of the outer circle of the sealing ring will not be affected during the welding process, thereby effectively ensuring the overall sealing effect.

[0036] In some embodiments of the present invention, the outer edges of the first positioning block 310 and the second positioning block 320 are flush with the outer edge of the sealing ring; or the outer edges of the first positioning block 310 and the second positioning block 320 protrude from the outer edge of the sealing ring.

[0037] It can be understood that the outer edge of the positioning block is flush with the outer edge of the sealing ring or exceeds the outer edge of the sealing ring, which can basically achieve full coverage of the sealing ring by the positioning block. Such a setting can enable the two sealing rings to be more accurately positioned and firmly fixed, further improving the welding quality and yield rate.

[0038] In some embodiments of the present invention, the groove 110 , the first sealing ring 210 , the second sealing ring 220 , the first positioning block 310 , and the second positioning block 320 are coaxially arranged.

[0039] It can be understood that such a configuration can bring the various components closer together, reduce the distance between the inner circles of the first sealing ring 210 and the second sealing ring 220, improve the positioning and stability of the welding process, make the operation more convenient, and improve work efficiency.

[0040] In some embodiments of the utility model, the first positioning block 310 and the second positioning block 320 are both provided with an operating through hole 400; further, the size of the operating through hole 400 is greater than or equal to the size of the inner ring of the sealing ring; further, an operating through hole 400 is also provided at the center of the support seat 100, and the size of the operating through hole 400 is smaller than the size of the groove 110.

[0041] It can be understood that during the welding process, the operator holds the welding gun and sequentially passes through the second positioning block 320 to operate the through hole 400, the inner ring of the second sealing ring 220, the first positioning block 310 to operate the through hole 400, and the inner ring of the first sealing ring 210 to weld the two inner rings of the sealing rings, which makes the operation more convenient.

[0042] It should be noted that the size of the operating through hole 400 is greater than or equal to the size of the inner ring of the sealing ring, where "greater than" is understood to be slightly greater, so as to reserve space for welding operations. If the value exceeds by a large amount, it will affect the flatness of the sealing ring surface during the welding process, affecting the subsequent sealing effect after combination with other sealing rings.

[0043] In some embodiments of the present invention, Figure 2 As shown, the first positioning block 310 is composed of a plurality of blocks.

[0044] It is understandable that the first positioning block 310 may be a whole or may be composed of a plurality of blocks. If the first positioning block 310 is composed of a plurality of blocks, the installation and removal process of the clamp is more convenient and quick.

[0045] The use process of the utility model clamp is as follows:

[0046] First, the first sealing ring 210 is accurately placed in the groove 110 of the support seat 100 to ensure its stable position during the welding process; then, the first positioning block 310 is placed on the top of the first sealing ring 210. The first positioning block 310 not only plays a role in positioning the first positioning block 310, but also provides necessary support and stability during the welding process; then, the second sealing ring 220 is placed on the top of the first positioning block 310 to complete the assembly of the sealing rings; finally, the second positioning block 320 is placed on the top of the second sealing ring 220. The second positioning block 320 plays a role in positioning the second sealing ring 220 to ensure that it maintains the correct position and posture during the welding process.

[0047] To sum up, the clamp for sealing ring welding of the utility model breaks through the technical bottleneck of difficult positioning and unstable fixation in traditional welding methods. The various components work together to achieve precise positioning and firm fixation of the sealing ring, ensuring the stability and position accuracy of the sealing ring during the welding process, thereby improving the welding quality and yield rate, and also improving work efficiency and convenience, providing a solid foundation for high-quality welding operations.

[0048] In addition, the utility model not only improves the applicability and versatility of the clamp, but can also adapt to sealing rings of different specifications and sizes, broadening the application scope of the equipment; and the clamp structure is simple and easy to use, and operators can quickly get started and efficiently complete welding work, focusing on operational convenience and humanized design.

[0049] In short, the sealing ring welding fixture of the utility model demonstrates excellent stability and practicality by virtue of its precise positioning mechanism, stable clamping device, efficient welding process and integrated compact design. It provides an efficient and reliable solution for sealing ring welding and has broad market application potential and promotion value.

[0050] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and substitutions can be made without departing from the technical principle of the present invention. These improvements and substitutions should also be regarded as the protection scope of the present invention.
