Description

Technical Field

[0001] This utility model relates to the field of butt welding fixture technology, and in particular to a simple and quick butt welding fixture for round pipes. Background Technology

[0002] The simple and quick round pipe butt welding fixture is an industrial welding auxiliary device that helps workers align and fix round pipes, thereby facilitating the butt welding operation between round pipes and improving the quality of round pipe welding.

[0003] However, since the round pipe needs to be clamped and aligned before welding, most of the existing simple and quick welding fixtures for round pipes on the market are not convenient to rotate after clamping the round pipe, making it difficult to weld the joint between the round pipes, which brings inconvenience to the welding operation of the workers.

[0004] Therefore, those skilled in the art have provided a simple and quick butt welding fixture for round tubes to solve the problems mentioned in the background art. Utility Model Content

[0005] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide a simple and quick welding fixture for round tubes. The rollers in the rotating mechanism rotate in the rolling groove, and the transmission gear fixedly connected to the rotating rod meshes with the meshing teeth on the rotating ring, so that two round tubes can rotate simultaneously on the base, which facilitates the welding operation for the workers.

[0006] To achieve the above objectives, this utility model provides a simple and quick butt welding fixture for round tubes, including a base, a fixing frame, and a clamping mechanism. The front and rear ends of the upper end of the base are fixedly connected to the fixing frame. The clamping mechanism includes two connecting blocks and two bidirectional threaded rods. The middle part of the outer wall of the bidirectional threaded rod is rotatably connected to the connecting blocks.

[0007] The upper end of the base is provided with a rotating mechanism, which includes multiple rollers, four rotating rings and rotating rods. Three shafts are fixedly connected to the inner wall of the fixed frame on the side near the center of the connecting block. The front end and rear end of the lower end of the connecting block are fixedly connected to the rotating rings. Rolling grooves are opened on the side of the rotating rings away from the center of the connecting block, and the rollers rotate in the rolling grooves.

[0008] Multiple meshing teeth are fixedly connected to the outer walls of both rotating rings. A rotating groove is opened in the middle of the interior of the base. The front and rear ends of the rotating rod are rotatably connected to the rotating groove. A transmission gear is fixedly connected to the outer wall of the rotating rod away from the center of the base. The upper end of the transmission gear passes through the base and meshes with the meshing teeth.

[0009] The above technical solution allows the rollers to rotate within the rolling grooves on the rotating rings, and the two transmission gears fixedly connected to the rotating rods mesh with the meshing teeth on the two rotating rings, enabling the two round tubes to rotate simultaneously on the base, thus facilitating welding operations for the workers.

[0010] Furthermore, pads are fixedly connected to the four corners of the lower end of the base, and the outer wall of the shaft body is rotatably connected to the rollers;

[0011] By using the above technical solution, the friction between the base and the ground is increased by making the four pads fixedly connected to the lower end of the base contact the ground, thus preventing the device from sliding or shifting during welding.

[0012] Furthermore, both sides of the outer wall of the bidirectional threaded rod are threadedly connected to clamping blocks, and the clamping blocks slide between the rotating rings;

[0013] The above technical solution allows the bidirectional threaded rod to be threadedly connected to the clamping block, enabling the rotating bidirectional threaded rod to drive the clamping block to move between the rotating rings, changing the distance between the clamping blocks, thereby clamping and fixing the round tube or loosening and removing it.

[0014] Furthermore, knobs are fixedly connected to both sides of the bidirectional threaded rod, and the outer walls of the two rotating rings are provided with wavy protrusions;

[0015] The above technical solution allows workers to easily rotate the bidirectional threaded rod on the connecting block by fixing knobs on both sides of the rod. The outer walls of the two rotating rings near the center of the base are designed to be wavy, which increases the friction between the worker's hand and the rotating rings, making it easier to rotate the rings.

[0016] Furthermore, bearings are fixedly connected to the outer wall of the rotating rod near the center of the base, and the outer wall of each bearing is fixedly connected to the inner wall of the rotating groove.

[0017] By using the above technical solution, the outer wall of the bearing is fixedly connected to the rotating groove, while the inner wall is fixedly connected to the rotating rod. This reduces the contact area between the long rotating rod and the base, thereby reducing the rotational resistance caused by friction and allowing workers to rotate the two round tubes more easily at the same time.

[0018] This utility model has the following beneficial effects:

[0019] This utility model proposes a simple and quick welding fixture for round tubes. The rollers in the rotating mechanism rotate in the rolling grooves on the rotating rings, and the two transmission gears fixedly connected to the rotating rod mesh with the meshing teeth on the two rotating rings, so that the two round tubes can rotate simultaneously on the base, thereby facilitating the worker to perform a circumferential welding operation on the butt joint between the round tubes.

[0027] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of specific embodiments. Obviously, the described specific embodiments are only a part of the specific embodiments of the present invention, and not all of them. Based on the specific embodiments of the present invention, all other specific embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0028] Reference Figure 1-5This utility model provides a specific embodiment: a simple and quick welding fixture for round tubes, including a base 1, a fixing frame 3 and a clamping mechanism 4. The front end and the rear end of the upper end of the base 1 are fixedly connected to the fixing frame 3. The clamping mechanism 4 includes two connecting blocks 401 and two bidirectional threaded rods 402. The middle part of the outer wall of the bidirectional threaded rods 402 is rotatably connected to the connecting blocks 401.

[0029] The upper end of the base 1 is provided with a rotating mechanism 5, which includes multiple rollers 502, four rotating rings 503 and rotating rods 507. Three shafts 501 are fixedly connected to the inner wall of the fixed frame 3 near the center of the connecting block 401. The front end and rear end of the lower end of the connecting block 401 are fixedly connected to the rotating rings 503. The rotating rings 503 are provided with rolling grooves 504 on the side away from the center of the connecting block 401, and the rollers 502 rotate in the rolling grooves 504.

[0030] Multiple meshing teeth 505 are fixedly connected to the outer walls of the two rotating rings 503. A rotating groove 506 is opened in the middle of the base 1. The front and rear ends of the rotating rod 507 are rotatably connected to the rotating groove 506. A transmission gear 509 is fixedly connected to the side of the outer wall of the rotating rod 507 away from the center of the base 1. The upper end of the transmission gear 509 passes through the base 1 and meshes with the meshing teeth 505.

[0031] The rollers 502 in the rotating mechanism 5 rotate in the rolling grooves 504 on the rotating ring 503, and the two transmission gears 509 fixedly connected to the rotating rod 507 mesh with the meshing teeth 505 on the two rotating rings 503, so that the two round tubes can rotate on the base 1 at the same time, which makes it easier for the workers to perform a circumferential welding operation on the joint gap between the round tubes.

[0032] At the four corners of the lower end of the base 1, pads 2 are fixedly connected. The outer wall of the shaft 501 is rotatably connected to the roller 502. By making the four pads 2 fixedly connected to the lower end of the base 1 contact the ground, the friction between the base 1 and the ground is increased, preventing the device from sliding or shifting during welding. Both sides of the outer wall of the bidirectional threaded rod 402 are threadedly connected to clamping blocks 403. The clamping blocks 403 slide between the rotating rings 503. By making the bidirectional threaded rod 402 threadedly connected to the clamping blocks 403, the rotating bidirectional threaded rod 402 can drive the clamping blocks 403 to move between the rotating rings 503, changing the distance between the clamping blocks 403, thereby clamping and fixing or loosening and removing the round tube. Both sides of the bidirectional threaded rod 402 are fixedly connected to knobs 404. The outer walls of the two rotating rings 503 are provided with wavy protrusions. The knobs 404 fixedly connected on both sides of the 02 allow the operator to easily rotate the bidirectional threaded rod 402 on the connecting block 401. The outer walls of the two rotating rings 503 near the center of the base 1 are designed with a wave-like shape to increase the friction between the operator's hand and the rotating rings 503, making it easier to rotate the rotating rings 503. The outer wall of the rotating rod 507 near the center of the base 1 is fixedly connected to the bearings 508. The outer walls of the bearings 508 are fixedly connected to the inner walls of the rotating grooves 506. By fixing the outer walls of the bearings 508 to the rotating grooves 506 and the inner walls to the rotating rod 507, the contact area between the long rotating rod 507 and the base 1 can be reduced, reducing the rotational resistance caused by friction, allowing the operator to rotate the two round tubes simultaneously more easily.

[0033] Working principle: When using this simple and quick round pipe welding fixture, the operator first places the device on the ground, then places two round pipes through the rotating ring 503 and between the two sets of clamping blocks 403, with the welding ends touching. Then, the knob 404 drives the bidirectional threaded rod 402 to rotate, causing the clamping blocks 403 to move closer together to clamp the round pipes and fix their position. Next, the roller 502 rotates in the rolling groove 504 on the rotating ring 503, and engages with the transmission gear 509 and the meshing gear 505. The operator can rotate one side of the rotating ring 503 to make the two round pipes rotate simultaneously on the base 1, which facilitates the welding operation of the round pipe joints using a welding torch.

[0034] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing specific embodiments, those skilled in the art can still modify the technical solutions described in the foregoing specific embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
