Description

Technical Field

[0001] The utility model belongs to the technical field of steel component welding and processing, and particularly relates to a steel component welding and fixing tooling. Background Technique

[0002] Steel component welding refers to the process of joining two or more pieces of metal together using an electric arc, resistance heat, or other heat sources. In steel structure engineering, welding is a common joining method, which has the characteristics of high strength, high stiffness, good sealing performance, etc., and is widely used in various building structures.

[0003] In the current welding process of annular steel components, in order to ensure the welding quality, it is usually necessary to use fixing tooling to position and clamp the components. However, most of the traditional fixing tooling designs use a clamping method from the outside to the inside. This clamping structure has certain limitations because during the clamping process, the annular steel component is prone to uneven pressure, resulting in deformation of the component. This deformation not only affects the dimensional accuracy of the component, but also may have an adverse impact on the welding strength and service performance, thus leading to waste of materials and resources. Therefore, it is necessary to improve the existing fixing and clamping technology to reduce the deformation problem of annular steel components during the welding process. Content of the Utility Model

[0004] The technical problem to be solved by the utility model is to overcome the existing defects and provide a steel component welding and fixing tooling to solve the problem that during the clamping process, the annular steel component is prone to uneven pressure, resulting in deformation of the component. This deformation not only affects the dimensional accuracy of the component, but also may have an adverse impact on the welding strength and service performance, thus leading to waste of materials and resources as mentioned in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical scheme: A steel component welding and fixing tooling, including a fixed seat, the upper surface of the fixed seat is rotatably connected with a rotating disk through a rotating shaft, a sliding groove is formed through the surface of the rotating disk, a fixed block is fixedly connected to the upper surface of the fixed seat, a sliding rod is slidably connected inside the fixed block, the upper surface of the inner end of the sliding rod is fixedly connected with a sliding block, the sliding block is slidably connected inside the sliding groove, the sliding groove is an arc-shaped groove structure, and the sliding rod is slidably connected to the upper surface of the fixed seat through the fixed block.

[0006] Preferably, an extension rod is fixedly connected to the upper surface of the outer end of the sliding rod through a fixing bolt.

[0007] Preferably, the outer ends of the extension rod and the sliding rod are both arc-shaped surface structures.

[0008] Preferably, fixing structures are fixedly connected to the lower surfaces of the fixed seats through legs.

[0009] Preferably, an electric push rod is fixedly connected to the lower surface of the fixed seat, and the output end of the electric push rod is drivingly connected to a connecting rod.

[0010] Preferably, meshing teeth are provided on the outer surface of the connecting rod and the side surface of the rotating shaft.

[0011] Preferably, the rotating shaft and the connecting rod are meshed with each other through the meshing teeth.

[0012] Compared with the prior art, the utility model provides a steel member welding and fixing tooling, which has the following beneficial effects:

[0013] 1. Through structures such as the rotating disk provided in the utility model, when clamping and fixing a ring-shaped steel member before welding, place the fixing tooling in the middle part inside the ring-shaped steel member. Before starting the tooling, the front sliding block is at the innermost end of the sliding groove. Drive the rotating disk to rotate through the rotating shaft, so that the sliding block slides to the outermost end of the sliding groove, thereby pushing the sliding rod outwards. Clamp and fix ring-shaped steel members of different sizes through the outer top end of the sliding rod. All four sliding rods are abutted against the inner surface of the ring-shaped steel member. After the position of the fixing tooling is determined, fix the fixing tooling on the workbench of the welding equipment through bolts and the fixing structure. Effectively avoid the problem that during the clamping process, the ring-shaped steel member is easily subjected to uneven pressure, resulting in deformation of the member. This deformation not only affects the dimensional accuracy of the member, but also may have an adverse impact on the welding strength and service performance, thereby causing waste of materials and resources.

[0014] 2. Through the electric push rod provided in the utility model, during use, the connecting rod can slide on the lower surface of the fixed seat by extending or shortening the electric push rod. The connecting rod drives the rotating shaft to rotate through the meshing teeth, thereby driving the rotating disk to rotate, avoiding manual operation, realizing convenient automatic adjustment, and improving the operation efficiency and comfort.

[0015] 3. Through the extension rod provided in the utility model, when the length of the sliding rod is not enough to contact the inner wall of the ring-shaped steel member with a larger inner diameter, an extension rod can be fixedly connected to the upper surface of the sliding rod through a fixing bolt, so that the fixing tooling can clamp and fix steel members of different sizes, realizing the adaptability to ring-shaped steel members with different inner diameter sizes, expanding the use range of the fixing tooling; improving the operation efficiency and convenience, and reducing the operation inconvenience caused by size limitations.

Specific implementation manners

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0024] Please refer to Figures 1-5, the present utility model provides a technical solution: a welding and fixing tooling for steel members, including a fixed seat 3. The upper surface of the fixed seat 3 is rotatably connected with a rotating disc 9 through a rotating shaft 13. A sliding groove 10 is penetrated through the surface of the rotating disc 9. The upper surface of the fixed seat 3 is fixedly connected with a fixed block 4. A sliding rod 5 is slidably connected inside the fixed block 4. The upper surface of the inner end of the sliding rod 5 is fixedly connected with a sliding block 8. The sliding block 8 is slidably connected inside the sliding groove 10. The sliding groove 10 is an arc-shaped groove structure. The sliding rod 5 is slidably connected to the upper surface of the fixed seat 3 through the fixed block 4. Through the structures such as the rotating disc 9 provided, when it is necessary to clamp and fix a ring-shaped steel member before welding, place this fixing tooling in the middle part inside the ring-shaped steel member. Before starting the tooling, the sliding block 8 is at the innermost end of the sliding groove 10. Drive the rotating disc 9 to rotate through the rotating shaft 13, so that the sliding block 8 slides to the outermost end of the sliding groove 10, thereby pushing the sliding rod 5 outwards. Clamp and fix ring-shaped steel members of different sizes through the outer top end of the sliding rod 5. All four sliding rods 5 abut against the inner side surface of the ring-shaped steel member. After the position of the fixing tooling is determined, fix the fixing tooling on the working table of the welding equipment through bolts and the fixing structure 1, effectively avoiding the problem that during the clamping process, the ring-shaped steel member is easily subjected to uneven pressure, resulting in deformation of the member. This kind of deformation not only affects the dimensional accuracy of the member, but also may have an adverse impact on the welding strength and service performance, and further lead to waste of materials and resources.

[0025] In the present utility model, preferably, an extension rod 6 is fixedly connected to the upper surface of the outer end of the sliding rod 5 through a fixing bolt 7. Through the provided extension rod 6, when the length of the sliding rod 5 is not enough to contact the inner wall of a ring-shaped steel member with a larger inner diameter, the extension rod 6 can be fixedly connected to the upper surface of the sliding rod 5 through the fixing bolt 7, so that this fixing tooling can clamp and fix steel members of different sizes, realizing the adaptability to ring-shaped steel members with different inner diameter sizes, expanding the use range of the fixing tooling; improving the operation efficiency and convenience, and reducing the operation inconvenience caused by size limitations.

[0026] In the present utility model, preferably, the outer ends of both the extension rod 6 and the sliding rod 5 are arc-shaped surface structures.

[0027] In the present utility model, preferably, the lower surface of the fixed seat 3 is fixedly connected with a fixing structure 1 through a leg 2.

[0028] In the present utility model, preferably, an electric push rod 11 is fixedly connected to the lower surface of the fixed seat 3. The output end of the electric push rod 11 is drivingly connected with a connecting rod 12.

[0029] In the present utility model, preferably, meshing teeth 14 are provided on the outer side surface of the connecting rod 12 and the side surface of the rotating shaft 13.

[0030] In the present utility model, preferably, the rotating shaft 13 and the connecting rod 12 are meshed with each other through the meshing teeth 14. By providing the electric push rod 11, during use, the connecting rod 12 can slide on the lower surface of the fixed seat 3 through the elongation or shortening of the electric push rod 11. The connecting rod 12 drives the rotating shaft 13 to rotate through the meshing teeth 14, thereby driving the rotating disk 9 to rotate, avoiding manual operation, achieving convenient automatic adjustment, and improving the operation efficiency and comfort.

[0031] The working principle and usage process of the present utility model: During use, place the fixing tooling in the middle part inside the annular steel member, ensuring that the sliding block 8 is at the innermost end of the sliding groove 10. Start the electric push rod 11. Through the transmission of the meshing teeth 14 between the connecting rod 12 and the rotating shaft 13, the rotating disk 9 rotates, and the sliding block 8 slides to the outermost end of the sliding groove 10 accordingly. The sliding rod 5 is thus pushed outwards and touches the inner surface of the annular steel member. If the length of the sliding rod 5 is insufficient, fix the extension rod 6 on the upper surface of the sliding rod 5. Adjust the sliding rod 5 until all four sliding rods 5 are abutted against the inner surface of the annular steel member to ensure the accurate position of the fixing tooling. Finally, fix the fixing tooling on the working table of the welding equipment through bolts and the fixing structure 1 to complete the clamping and fixing of the annular steel member, avoiding deformation of the member and ensuring the welding precision and strength.

[0032] Although the embodiments of the present utility model have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
