[0028] like Figures 1-7As shown, a laser welding device for a distribution tube includes a tube 91 to be welded and a tube sheet 92. It includes a base 1, on which a clamping part 11 and a mounting part 15 are provided. A welding robotic arm 93 is provided on the mounting part 15. The clamping part 11 is provided with a fixed claw 111 and a movable claw 81 that is slidably arranged relative to the fixed claw 111. The base 1 is provided with a retaining groove 12 and a placement groove 13 for placing the tube sheet 92. The movable claw 81 slides closer to the fixed claw 111 to clamp the tube 91 to be welded and coaxial with the placement groove 13, and the end of the tube 91 to be welded abuts against the retaining groove 12.

[0029] Specifically, such as Figure 1 As shown, the base 1 is provided with a mounting part 15 for mounting the welding robotic arm 93. A threaded drive rod 82 is rotatably mounted on the clamping part 11. The threaded drive rod 82 is threadedly engaged with the movable claw 81. The threaded drive rod 82 can be rotated to allow the movable claw 81 to slide closer to the fixed claw 111 to clamp the pipe 91 to be welded. The tube plate 92 is coaxially sleeved on the pipe 91 to be welded so that the tube plate 92 abuts against the placement groove 13, and the other end of the pipe 91 abuts against the fixing groove 12. After the positioning of the pipe 91 and the tube sheet 92 to be welded is completed, the welding gun of the welding robot arm 93 can then perform a circular motion around the axis of the pipe 91, thereby coaxially welding the fixed pipe 91 and the tube sheet 92. The placement groove 13, the fixed claw 111 and the movable claw 81 of the base 1 are used to achieve coaxial positioning and fixation when welding the tube sheet 92 on the outside of the pipe 91 to be welded, thereby improving the coaxiality of the welding between the tube sheet 92 and the pipe 91 to be welded and facilitating the actual welding operation.

[0030] The welding robotic arm 93 and its driver program are common technical knowledge to those skilled in the art and will not be described in detail here.

[0031] In the above technical solution, the movable claw 81 slides close to the fixed claw 111 to clamp the tube 91 to be welded, and the tube sheet 92 is coaxially sleeved on the tube 91 to be welded so that the tube sheet 92 abuts against the placement groove 13, and the other end of the tube 91 to be welded abuts against the fixing groove 12, thereby completing the positioning of the tube 91 to be welded and the tube sheet 92. Then, the welding robot arm 93 can be used to weld the tube 91 to be welded and the tube sheet 92, realizing the coaxial positioning and fixing when welding the tube sheet 92 on the outside of the tube 91 to be welded, improving the coaxiality of the welding between the tube sheet 92 and the tube 91 to be welded, and facilitating the actual welding operation.

[0032] As a further embodiment provided in this utility model, the bottom surface of the retaining groove 12 is an arc surface.

[0033] Specifically, such as Figure 4As shown, the bottom surface of the retaining groove 12 is an arc surface, which allows the retaining groove 12 to retain and fix the L-shaped pipe to be welded 91. That is, the long end of the L-shaped pipe to be welded 91 is clamped and fixed by the fixed claw 111 and the movable claw 81, while the short end of the L-shaped pipe to be welded 91 abuts against the bottom surface of the retaining groove 12, thereby further improving the applicability and fixing stability of the pipe to be welded 91.

[0034] As a further embodiment of this utility model, it also includes a clamping seat 3 that is flipped and arranged on the base 1. The clamping seat 3 is provided with a snap-fit ​​part 31. The clamping seat 3 is flipped so that the snap-fit ​​part 31 snaps into the snap-fit ​​groove 14 opened on the base 1, and the clamping seat 3 clamps the tube plate 92 into the placement groove 13.

[0035] Specifically, the clamping seat 3 is provided with a rotating part 34, which is rotatably mounted on the mounting part 16 provided on the base 1. When the tube sheet 92 is placed in the placement groove 13, the clamping seat 3 can be flipped to approach the base 1 so that the clamping seat 3 can press and fix the tube sheet 92 in the placement groove 13, thereby further improving the fixing stability of the tube sheet 92 and the tube to be welded 91. Secondly, the clamping seat 3 and the base 1 are engaged by the snap-fit ​​part 31 and the snap-fit ​​groove 14, which facilitates the flipping, fixing and unlocking of the clamping seat 3.

[0036] As a further embodiment of this utility model, the clamping seat 3 is provided with an exposed groove 32. The clamping seat 3 clamps the tube plate 92 in the placement groove 13 so that the exposed groove 32 faces the tube plate 92, and the exposed groove 32 and the tube plate 92 are coaxially distributed.

[0037] Specifically, such as Figure 5 As shown, the clamping seat 3 has an exposed groove 32. When the clamping seat 3 is flipped and close to the base 1 to clamp the tube sheet 92 in the placement groove 13, the exposed groove 32 is coaxially distributed with the tube sheet 92 to expose the welding position of the tube sheet 92, thereby facilitating the welding operation between the welding robot arm 93 and the tube to be welded 91.

[0038] As a further embodiment of this utility model, a flexible barrier 5 is provided on the clamping seat 3. The clamping seat 3 is flipped to drive the snap-fit ​​part 31 to snap into the snap-fit ​​groove 14 so that the flexible barrier 5 is inserted into the anti-locking groove 12.

[0039] Specifically, such as Figure 1 As shown, when the clamping seat 3 flips and approaches the base 1 to clamp the tube plate 92 into the placement groove 13, the flexible enclosure 5 is inserted into the abutment groove 12 to further improve the fixing stability between the clamping seat 3 and the base 1.

[0040] As a further embodiment of this utility model, a movable block 4 is slidably provided on the clamping seat 3. The movable block 4 is provided with an abutment part 41 and a gripping part 42. The clamping seat 3 flips the clamping tube plate 92 into the placement groove 13 so that the abutment part 41 faces into the fixing groove 12. The movable block 4 is driven to slide so that the abutment part 41 presses the tube to be welded 91 into the fixing groove 12.

[0041] Specifically, the movable block 4 is slidably disposed in the vertical groove 33 opened on the clamping seat 3. When the clamping seat 3 flips to clamp the tube plate 92 in the placement groove 13, the contact part 41 faces the fixing groove 12. At this time, the gripping part 42 can be manually pressed to drive the contact part 41 to press the end of the L-shaped tube to be welded 91 into the bottom of the fixing groove 12, thereby further improving the stability of fixing the tube to be welded 91 and improving the coaxiality of the tube to be welded 91 and the tube plate 92 during welding.

[0042] As a further embodiment of this utility model, a sliding seat 62 is symmetrically slidably arranged inside the pressing seat 3, and an abutment wheel 61 is rotatably arranged on the sliding seat 62. An abutment groove 43 is linearly arrayed on the movable block 4. The movable block 4 slides so that the sliding seat 62 drives the abutment wheel 61 to roll away from and contact the abutment groove 43 in sequence.

[0043] Specifically, such as Figure 3 As shown, the sliding seat 62 is symmetrically slidably disposed in the horizontal sliding groove 331 opened in the clamping seat 3, and the horizontal sliding groove 331 is provided with an elastic element 63 that drives the sliding seat 62 to slide towards the vertical sliding groove 33. The elastic element 63 always drives the sliding seat 62 and the abutting wheel 61 to move closer to the movable block 4. When the movable block 4 is driven to slide along the vertical sliding groove 33, several abutting grooves 43 on the movable block 4 contact the abutting wheel 61 in sequence to decelerate the movable block 4, which facilitates the actual sliding use of the movable block 4. When the abutting part 41 of the movable block 4 presses the end of the L-shaped pipe to be welded 91 against the bottom of the abutting groove 12, the abutting wheel 61 abuts against the abutting groove 43 to further improve the fixing stability of the movable block 4 against the pipe to be welded 91.

[0044] As a further embodiment provided by this utility model, a plurality of flexible abutment plates 7 are symmetrically arranged on the movable block 4. The flexible abutment plates 7 abut against the side wall of the abutment groove 12. The movable block 4 is driven to slide so that the flexible abutment plates 7 deform and enter the abutment groove 43.

[0045] Specifically, such as Figure 3As shown, several flexible abutment plates 7 are symmetrically arranged on the movable block 4. The flexible abutment plates 7 abut against the side wall of the fixing groove 12 to reduce the falling of debris or dust during the welding process into the fixing groove 12. When the movable block 4 is driven to slide away from the fixing groove 12, the flexible abutment plates 7 move and scrape against the side wall of the fixing groove 12 to clean the inside of the fixing groove 12. The flexible abutment plates 7 deform and enter the abutment groove 43 so as not to interfere with the normal sliding of the movable block 4. When the clamping seat 3 flips away from the base 1, the flexible abutment plates 7 can be cleaned.

[0046] As a further embodiment provided in this utility model, the flexible enclosure 5 is made of wear-resistant rubber.

[0047] As a further embodiment provided in this utility model, the flexible abutment 7 is made of wear-resistant rubber.
