Technical Field
[0001] This application relates to the field of pipe welding technology, and more specifically, to a welding apparatus for pipe connection. Background Technology
[0002] Metal pipes are tubular products made of metal materials, widely used in various industries, construction, transportation, chemical, machinery, and electronics fields. Depending on the metal material, manufacturing process, and application, metal pipes can be classified into several types. Metal pipe welding equipment is used for connecting metal pipes, primarily to join the two ends of metal pipes or pipes of different shapes using welding processes.
[0003] In existing technologies, for pipe welding, due to the irregular size and shape of the welded parts, it is difficult to achieve precise diameter alignment. Manual welding is generally used. However, manual welding has the following problems: low work efficiency, high labor costs, and the gas generated during the welding process has toxic side effects on the human body. In addition, manually welded products cannot guarantee that the weld joint of the two pipes is completely aligned, often resulting in incomplete welds and other issues, leading to unqualified welded products.

[0029] The first T-shaped block 22 is used to limit the first support plate 2 and prevent the first support plate 2 from detaching from the upper end of the operating table 1. The first telescopic rod 221 is used to push the first support plate 2 to slide along the first T-shaped groove 11.
[0030] The lower end of the first clamping plate 23 is slidably engaged with the third T-slot 21. A telescopic component is provided on one side of the lower end of the first clamping plate 23. Soft friction pads 231 are fixedly connected to the inner side of the first clamping plate 23 and the inner side of the first vertical plate 24.
[0031] The soft friction pad 231 is used to increase the friction at the contact point with the pipe, and the cooperation between the first clamping plate 23 and the first vertical plate 24 is used to fix and clamp the outer sides of the pipe.
[0032] A second telescopic rod 311 is fixedly connected to one side of the second T-block 31. The second T-block 31 is also slidably engaged with the first T-slot 11. One end of the second telescopic rod 311 is fixedly connected to one side of the first T-block 22.
[0033] The second telescopic rod 311 is used to push the second support plate 3 to slide along the first T-slot 11.
[0034] A through groove 321 is provided on one side of the second clamping plate 32. A first slot 331 is provided on the outer side of the second vertical plate 33. A through groove 332 is provided on the inner side wall of the first slot 331. A second slot 333 is provided on the inner side of the second vertical plate 33. The second slot 333 is connected to the through groove 332. The baffle 4 passes through the interior of the through groove 321 and the through groove 332. The first side plate 41 is slidably engaged with the first slot 331. The second side plate 42 is slidably engaged with the second slot 333.
[0035] The baffle 4 is used to limit and block the outer end of the pipe, the second slot 333 is used to place the second side plate 42, and the presence of the through slot 321 and the through slot 332 facilitates the free passage of the baffle 4.
[0036] The implementation principle of this embodiment is as follows: When welding is required on the pipe, firstly, the second telescopic rod 311 is extended and retracted according to the length of the pipe, causing the second support plate 3 to slide along the first T-slot 11 until the distance between the first support plate 2 and the second support plate 3 is adjusted to a suitable length. Then, the welding end of the pipe is oriented towards the center of the operating table 1, so that the welding end of the pipe is placed on the upper end of the first support plate 2, and the tail end of the pipe is placed on the upper end of the second support plate 3. Then, the telescopic component in the first support plate 2 is shortened, causing the first clamping plate 23 to move closer to the first vertical plate 24 until the first clamping plate 23 and the first vertical plate 24 are aligned with the pipe. The welding end is clamped and fixed, and the telescopic component in the second support plate 3 is shortened, so that the second clamping plate 32 and the second vertical plate 33 clamp and fix the tail end of the pipe. At this time, the first telescopic rod 221 can be controlled to extend and retract, driving the first support plate 2 to move along the first T-slot 11 toward the center of the operating table 1 until the welding end of the pipe is moved to the center of the operating table 1. Then, the other set of pipes on the second T-slot 12 is placed in the opposite way so that the welding ends of the two sets of pipes are in a state of mutual contact at the center of the operating table 1, so that the pipes will not shift in position during the welding process.
[0037] If the pipe is too long, the baffle 4 can be pushed to make the second side plate 42 pass through the inside of the through groove 321 and lock it in the second slot 333. At this time, the space between the second clamping plate 32 and the second vertical plate 33 is exposed so that the longer pipe can pass through freely.
[0038] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
