Description

Technical Field

[0001] This utility model relates to the field of weld joint technology in pipeline welding, and more specifically, to a pipeline welding joint fitting device for heating engineering. Background Technology

[0002] A pipe welding joint tool is a clamp that aligns two pipes. Using this clamp, it is easy to weld and fix the connection between two pipes. Pipe welding joint tools are used in many pipe connections. For example, in urban heating projects, pipe welding joint tools are also needed because the main pipes are relatively large.

[0003] Existing pipe welding fittings used in heating projects employ threaded rods and clamping blocks. By rotating the threaded rods on both sides, the clamping blocks are brought closer to and held onto the pipe. However, since the threaded rods rotate independently, synchronization cannot be guaranteed, resulting in misalignment of the pipe ends on both sides. Furthermore, the movement of the clamping blocks on both sides causes the pipes to be out of sync after positioning, leading to deviations in the pipe-to-pipe alignment and affecting the welding process. Therefore, a new pipe welding fitting for heating projects is needed to solve these problems. Utility Model Content

[0004] In view of this, the present invention proposes a pipe welding butt joint tool for heating engineering, including a disc and a centering component;

[0005] The disk is provided with through holes that match the diameter of the pipe to be docked;

[0006] The centering component includes:

[0007] A drive gear is disposed on the front wall of the disk and located beside the through hole;

[0008] An external gear ring is rotatably mounted on the front wall of the disk, and its inner diameter matches the inner diameter of the through hole.

[0009] It can rotate around the center of the through hole. The drive gear meshes with the outer diameter of the outer gear ring and can provide power for the rotation of the outer gear ring. The pipe to be connected can be inserted into the through hole and the outer gear ring.

[0010] The synchronous roller assembly includes multiple sets arranged around the external gear and can move toward the center of the disk through the meshing action of the external gear ring, enabling adjustment and positioning of the pipe to be docked.

[0011] Furthermore, a servo motor is provided on the rear wall of the disk corresponding to the drive gear. The output shaft of the servo motor passes through the disk and extends to the front wall of the disk. The drive gear is mounted on the output shaft of the servo motor.

[0012] Furthermore, each set of synchronous roller assemblies includes a transmission gear, a movable shaft, a drive rod, and a roller; the movable shaft is rotatably connected to the front wall of the disc and located outside the outer gear ring; the transmission gear is fixedly installed on the outer surface of the movable shaft and can mesh with the outer gear ring; the drive rods are in pairs, with one end of each fixedly installed on the outer surface of the movable shaft; when the outer gear ring rotates, it drives the drive rods to rotate through the meshing action of the transmission gear; the other ends of the two drive rods are rotatably connected to the rollers; the rollers can move closer to the pipe to be docked as the drive rods rotate, for adjustment and positioning.

[0013] Furthermore, the movable shaft is also equipped with a support frame, which is L-shaped, with one end vertically connected to the disc and the other end connected to the movable shaft, thus providing support for the movable shaft.

[0014] Furthermore, the synchronous roller assembly is provided in three sets, arranged sequentially around the outer gear ring.

[0015] Furthermore, a groove is formed on the outer surface of the roller, and the groove is arranged around the outer surface of the roller.

[0016] Furthermore, both the roller and the groove are axially aligned with the through hole.

[0017] Furthermore, the width of the groove is adapted to the width of the burr at the pipe joint position along the length of the pipe.

[0018] Furthermore, the three sets of synchronous roller assemblies are spaced equally around the outer gear ring.

[0019] This utility model provides a pipe welding and alignment tool for heating engineering, which has the following advantages: The welding and alignment tool, by setting a centering component, when activated by a servo motor, drives a gear to rotate an external gear ring. The external gear ring, in turn, drives three transmission gears to rotate synchronously, causing multiple drive rods to rotate synchronously. This allows three rollers to approach the outer wall of the heating engineering pipe. The clamping of the heating engineering pipe by the three rollers achieves three-point synchronous center positioning, ensuring that the two sides of the heating engineering pipe are on the same axis, thus guaranteeing the accuracy of the pipe alignment position.

[0025] Exemplary embodiments of the present disclosure will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided to enable a more thorough understanding of the present disclosure and to fully convey the scope of the disclosure to those skilled in the art. It should be noted that, unless otherwise specified, embodiments and features of the present invention can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0026] See Figure 1-2 As shown, a pipe welding fitting for heating engineering includes a disc 1 and a centering assembly. The disc 1 has a through hole 12 that matches the diameter of the pipe to be welded. The centering assembly includes a drive gear 2, an external gear ring 3, and a synchronous roller assembly 4. The drive gear 2 is located on the front wall of the disc 1 and next to the through hole 12. The external gear ring 3 is rotatably mounted on the front wall of the disc 1. The inner diameter of the external gear ring 3 is the same as the inner diameter of the through hole 12, and it can rotate around the center of the through hole 12. The drive gear 2 meshes with the outer diameter of the external gear ring 3, providing power for the rotation of the external gear ring 3. The pipe to be welded can pass through the through hole 12 and the external gear ring 3. The synchronous roller assembly 4 includes multiple sets, arranged around the external gear 3, and can move towards the center of the disc 1 through the meshing action of the external gear ring 3, enabling adjustment and positioning of the pipe to be welded.

[0027] Reference Figure 2 As shown, a servo motor 5 is provided on the rear wall of the disk 1 corresponding to the drive gear 2. The output shaft of the servo motor 5 passes through the disk 1 and extends to the front wall of the disk 1. The drive gear 2 is mounted on the output shaft of the servo motor 5.

[0028] Reference Figure 1-2 As shown, each set of synchronous roller assemblies 4 includes a transmission gear 41, a movable shaft 42, a drive rod 43, and a roller 44. The movable shaft 42 is rotatably connected to the front wall of the disc 1 and is located outside the outer gear ring 3. The transmission gear 41 is fixedly installed on the outer surface of the movable shaft 42 and can mesh with the outer gear ring 3. The drive rods 43 are in pairs, with one end of each pair fixedly installed on the outer surface of the movable shaft 42. When the outer gear ring 3 rotates, it drives the drive rods 43 to rotate through the meshing action of the transmission gear 41. The other ends of the two drive rods 43 are rotatably connected to the rollers 44. The rollers 44 can move closer to the pipe to be docked as the drive rods 43 rotate, and are adjusted and positioned.

[0029] Reference Figure 1 As shown, the movable shaft 42 is also equipped with a support frame 46. The support frame 46 is L-shaped, with one end vertically connected to the disk 1 and the other end connected to the movable shaft 42, which can support the movable shaft 42. As shown in the figure, one end of the movable shaft 42 is connected to the disk 1 and the other end is connected to the support frame 46.

[0030] Continue to refer to Figure 1 As shown, the synchronous roller assembly 4 is arranged in three groups, sequentially surrounding the outer gear ring 3. In this embodiment, the three groups of synchronous roller assemblies 4 are spaced equally around the outer gear ring 3.

[0031] Reference Figure 1-2 As shown, a groove 45 is formed on the outer surface of the roller 44, and the groove 45 is arranged around the outer surface of the roller 44. Specifically, the ends of the heating pipes on both sides are joined in the groove 45. The ends of the pipes have burrs and are subjected to compression, so that the outer diameter of the ends of the pipes is larger than the outer diameter of other parts. Placing them in the groove 45 facilitates the joining work of the heating pipes on both sides.

[0032] In this embodiment, the roller 44 and the groove 45 are both axially aligned with the through hole 12.

[0033] In this embodiment, the width of the groove 45 is adapted to the width of the burr at the pipe joint position along the length of the pipe.

[0034] The present invention discloses a pipe welding and mating device for heating engineering, which has the following advantages: This welding and mating device, by setting a centering component, when activated by a servo motor, drives a gear to rotate an external gear ring. The external gear ring, in turn, drives three transmission gears to rotate synchronously, causing multiple drive rods to rotate synchronously. This allows three rollers to approach the outer wall of the heating engineering pipe. The clamping of the heating engineering pipe by the three rollers achieves three-point synchronous center positioning, ensuring that the two sides of the heating engineering pipe are on the same axis, thus guaranteeing the accuracy of the pipe alignment position.

[0035] This utility model embodiment also discloses a method for using a pipe welding joint tool for heating engineering, including: placing a disc 1 with a through hole 2 on the outer surface of one of the heating engineering pipes; pulling the other heating engineering pipe to align the ends of the two heating engineering pipes, with the alignment position within the groove 45; starting the servo motor 5 to drive the drive gear 2 to rotate; under the transmission meshing of the external gear ring 3 with the drive gear 2 and the transmission gear 41, the external gear ring 3 drives the three transmission gears 41 to rotate synchronously; the three rollers 44 follow the movement and gradually move closer to the aligned heating engineering pipes; with the three rollers 44 providing three-point positioning for the two aligned heating engineering pipes, the center positioning of the heating engineering pipes is achieved, ensuring the accuracy of the alignment position.

[0036] Specifically, the present invention discloses a method for using a pipe welding joint tool for heating engineering, which is simple to operate and can achieve accurate alignment of pipe joints in engineering projects.

This is only for the convenience of description and does not indicate or imply that the device or element must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation of this utility model.
