Description

Technical Field

[0001] The utility model relates to the technical field of welding tooling, in particular to a pipe welding error-proofing device. Background Art

[0002] Welding is a manufacturing process that joins metals or other thermoplastic materials such as plastics by heating, high temperature or high pressure. Pipe butt welding is the most commonly used application in welding technology. Pipe butt welding is a method of connecting two pipe ends together by welding to form a seamless connection. In the field of pipe welding, if the operation is improper or the welded product is displaced, various welding defects are prone to occur, such as weak welds, pores, slag inclusions, etc. These defects will not only reduce the strength and sealing of the welding position, but may also cause product failure and damage. By implementing welding error prevention measures, the occurrence of welding defects can be minimized and the quality and reliability of the welding position can be improved.

[0003] At present, a Chinese patent with publication number CN220498219U discloses a special positioning tool for welding pipe fittings and plate fittings, which includes a base, an axis core and a pad. The base includes a bottom plate for supporting the plate, and the upper surface of the bottom plate is fixedly connected to a first boss for positioning the plate. The axis core includes a prism, which is detachably connected to the first boss. The prism is used for positioning the pipe fitting, and the pad is used to be inserted between the plate and the pipe fitting to control the distance between the plate and the pipe fitting.

[0004] Although the above-mentioned tooling can quickly position the pipe and plate specimens through the cooperation of the shaft core and the base, and can prevent the pipe and plate from offsetting and misaligning during the positioning welding process, the positioning and error prevention means of the above-mentioned tooling are all achieved through manual operation, with a low degree of industrialization, and its positioning method is simple, with a limited error prevention effect.

DETAILED DESCRIPTION

[0023] The above and other technical contents, features and functions of the present invention are described in detail below with reference to the attached Figure 1 To Attachment Figure 5 The detailed description of the embodiments will clearly show that the structural contents mentioned in the following embodiments are all based on the drawings in the specification.

[0024] Various exemplary embodiments of the present invention will be described below with reference to the accompanying drawings. Example

[0025] A pipe welding error-proofing device comprises a tooling base plate 1, a tooling plate 2 is installed on the upper part of the tooling base plate 1, and the tooling base plate 1 and the tooling plate 2 are fixed by bolts. The device is intended to effectively prevent errors in seamless welding between two groups of pipes, ensure the safety of the welding process and the reliability of the welding quality, and reduce welding defects.

[0026] The front end of the tooling plate 2 is provided with a support rod 3 fixed to the upper end of the tooling base plate 1, and a group of hollow limiting tubes 4 are fixedly welded at the middle position of the support rod 3. A first pipe fitting 5 to be welded is inserted into the limiting tube 4. The first pipe fitting 5 to be welded is inserted and installed in the limiting tube 4, and its position will not loosen at will.

[0027] A group of placement grooves 6 are opened at the upper end of the tooling plate 2, and a pipe pad 7 is fixedly welded inside the placement groove 6. A second pipe to be welded 8 is arranged above the pipe pad 7. The pipe pad 7 wraps the lower half structure of the second pipe to be welded 8 as a whole, forming a support carrier for the lower part of the second pipe to be welded 8.

[0028] It is further provided that a clamping block 9 is provided on the right side of the second pipe fitting 8 to be welded, and the clamping block 9 can move laterally. When the clamping block 9 contacts the second pipe fitting 8 to be welded, the second pipe fitting 8 to be welded is positioned and clamped. The clamping block 9 moves to the left until it covers the upper right side of the second pipe fitting 8 to be welded. The clamping block 9 cooperates with the pipe gasket 7 to achieve a positioning and clamping effect on the second pipe fitting 8 to be welded.

[0029] A transverse block 10 is fixedly welded to the right side of the clamping block 9 , two positioning columns 11 are fixedly provided on the upper end of the tooling plate 2 , and the transverse block 10 is slidably assembled outside the positioning columns 11 , and the transverse block 10 moves transversely along the direction of the positioning columns 11 .

[0030] It is further provided that a connecting block 12 is fixedly welded to the right end above the transverse moving block 10 , and a pressing block 9 driving mechanism for controlling the movement of the pressing block 9 is provided on one side of the connecting block 12 .

[0031] Specifically, the driving mechanism of the clamping block 9 includes a force-bearing plate 13 integrally formed with the connecting block 12 and a force-applying plate 14 in contact with the force-bearing plate 13. The contact surfaces of the force-bearing plate 13 and the force-applying plate 14 are both inclined surfaces, and the two form an inclined wedge structure. A synchronous movable plate 15 is fixedly welded to one side of the force-applying plate 14, and a connecting sleeve 16 that can move forward and backward is fixed to one end of the synchronous movable plate 15. In the above structure, when the connecting sleeve 16 moves forward, the force-applying plate 14 is driven forward at the same time by the synchronous movable plate 15. Due to the inclined wedge structure of the force-applying plate 14 and the force-bearing plate 13, the force-bearing plate 13 moves to the left after being subjected to force, and drives the clamping block 9 to move to the left through the connecting block 12. At this time, the clamping block 9 performs the above-mentioned action of covering and clamping the second pipe fitting 8 to be welded.

[0032] It is further provided that a raised plate 20 is fixed on one side of the connecting block 12 on the tooling base plate 1, a connecting column 21 is fixedly welded on the left side of the raised plate 20, a limiting clamping plate 22 is fixedly welded on the left end of the connecting column 21, the connecting block 12 is slidably assembled on the outside of the connecting column 21, and a reset spring 23 installed on the outside of the connecting column 21 is provided between the left end of the connecting block 12 and the limiting clamping plate 22. When there is no need to clamp the second pipe fitting 8 to be welded, the connecting sleeve 16 needs to be moved backward. At this time, the reset spring 23 can push out the connecting block 12, so that the clamping block 9 naturally resets to the initial position to the right, thereby realizing the automatic reset function.

[0033] It is further provided that a pushing cylinder 17 is provided at the upper end of the tooling base plate 1, and a pipe positioning block 18 which can extend into the second pipe to be welded 8 is fixedly provided on the piston rod of the pushing cylinder 17, and two sets of slide rails 19 are fixedly provided at both ends of the placement groove 6, the pipe positioning block 18 is slidably assembled on the outside of the slide rails 19, and the connecting sleeve 16 is fixedly welded to the outside of the pipe positioning block 18. In the above structure, a pushing cylinder 17 is provided as a power source for controlling the movement of the connecting sleeve 16, and an additional pipe positioning block 18 is installed. When the pushing cylinder 17 controls the clamping block 9, the pipe positioning block 18 simultaneously moves forward and extends into the second pipe to be welded 8, so that the effect of simultaneously tightening the outside and the inside of the second pipe to be welded 8 is achieved by using a practical set of power sources.

[0034] The above is a further detailed description of the present invention in combination with a specific implementation method, and it cannot be determined that the specific implementation of the present invention is limited to this; for technical personnel in the field of the present invention and related technical fields, based on the technical solution of the present invention, the expansion and replacement of operating methods and data should all fall within the protection scope of the present invention.
