Description

Technical Field

[0001] The utility model relates to a flange welding machine with an automatic centering effect, belonging to the technical field of flange processing. Background Technique

[0002] A flange is a mechanical component used to connect pipes, valves, pumps and other equipment to form a pipeline system. It is usually in the shape of a disc and has a number of bolt holes. Through these holes, two flanges can be fixed together, and gaskets are used to seal the interface between them. The design of the flange allows for easy disassembly and reconnection, which is very convenient when maintenance, repair or system modification is required. During the flange processing, in order to ensure the sealing performance and mechanical strength of the connection and enable it to withstand the pressure, temperature and mechanical load in the pipeline system, welding processing is required. Therefore, a welding machine is needed.

[0003] However, during the use of the existing flange welding machines, an automatic centering mechanism may be lacking. The lack of a centering mechanism may lead to inaccurate docking between the flange and the pipe or other connecting components, resulting in uneven welds, affecting the welding quality and the sealing performance of the connection. Improper docking may cause uneven welding stress, increasing the risk of cracks and fractures. In addition, inaccurate docking may also cause the installation position of the flange to shift, thus affecting the alignment and operation efficiency of the entire pipeline system.

[0004] Therefore, a flange welding machine with an automatic centering effect is proposed. Content of the Utility Model

[0025] Embodiment 1

[0026] As Figures 1-4As shown in the figure, an embodiment of the present utility model provides a flange welding machine with an automatic centering effect, which includes a base plate 1. A frame 2 is fixedly installed on the top of the base plate 1. A connecting frame 3 is fixedly installed on the top of the frame 2. A welding head 4 is fixedly installed at the bottom of the connecting frame 3. A centering assembly 5 is arranged on the top of the base plate 1. The centering assembly 5 includes a base 501, a bidirectional screw 503, a threaded block 504, a connecting rod 505 and a fixing block 506. The base 501 is fixedly installed on the top of the base plate 1. The bidirectional screw 503 is movably connected to the inside of the base 501. The threaded blocks 504 are threadedly connected to the left and right sides of the surface of the bidirectional screw 503. Two connecting rods 505 are movably connected to the front and back sides of the surface of the threaded block 504. The fixing block 506 is movably connected to the inside of the connecting rod 505 through a rotating shaft. A servo motor 502 is fixedly connected to the right side of the surface of the base 501. The output end of the servo motor 502 is fixedly connected to the bidirectional screw 503 for driving the bidirectional screw 503 to rotate. Clamping plates 511 are respectively opened on the left and right sides of the top of the frame 2. The upper end of the connecting rod 505 penetrates through the clamping plate 511 and is connected to the fixing block 506. The outside of the connecting rod 505 is movably connected to the inside of the clamping plate 511 through a rotating shaft. A through hole 507 is opened on the inside of the fixing block 506. A rotating rod 508 is movably connected to the inside of the fixing block 506. A connecting cylinder 509 is fixedly installed on the inside of the rotating rod 508. Lead screws 510 are respectively threadedly connected to the front and back sides of the connecting cylinder 509. The clamping plate 511 is fixedly connected to the inside of the lead screw 510.

[0027] Through the setting of the centering assembly 5, it can ensure that the flanges can be accurately aligned before welding, so as to achieve uniform and high-quality welds, thereby significantly improving the sealing performance and structural integrity of the connection, reducing the stress concentration during the welding process, lowering the risk of cracks or structural failures in the future, and optimizing the efficiency and speed of the welding process, improving the work efficiency.

[0028] Embodiment 2

[0029] In one embodiment, limit blocks 6 are fixedly installed on the left and right sides of the surface of the bidirectional screw 503. The diameter of the limit block 6 is larger than the diameter of the threaded block 504. A slider 7 is fixedly installed at the bottom of the fixing block 506. Chute grooves 8 are respectively opened on the left and right sides of the top of the frame 2. The slider 7 is slidably connected to the inside of the chute groove 8.

Through the setting of the guide block 9 and the guide groove 10, a guiding effect can be achieved to prevent the threaded block 504 from shifting during movement.

[0031] When the utility model is working: by rotating the lead screw 510, the clamping plate 511 can be driven to move inward under the action of threaded connection, so as to clamp and fix the flange. At this time, the servo motor 502 can be started to drive the bidirectional screw 503 at the output end to rotate. While the bidirectional screw 503 is rotating, the threaded block 504 will be driven to move outward under the action of threaded connection. When the threaded block 504 moves, the lower end of the connecting rod 505 will be driven to move outward, so that the upper end will swing inward, driving the fixing blocks 506 on both sides to move inward at the same time, so as to perform centering treatment on the flange. At this time, the flange can be welded by the welding head 4. During the welding process, the connecting cylinder 509 can be driven to rotate by rotating the rotating rod 508, so as to drive the flange to flip, so as to facilitate full-round welding treatment.

[0032] The above is only the specific implementation manner of the utility model, but the protection scope of the utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the utility model can easily think of various changes or substitutions thereof, and these should all be covered within the protection scope of the utility model. Therefore, the protection scope of the utility model should be subject to the protection scope of the claims.
