[0028] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0029] The terms "left," "right," "front," "back," "up," and "down" used in the following description refer to the orientation from the perspective of the front view.

[0030] In some embodiments, please refer to the accompanying drawings. Figures 1-6 An adjustable laser welding device includes a base 101, a bracket 102, a support platform 103, a clamping and rotating mechanism 2, a pressing and positioning mechanism 3, a linear module 4, a laser welding device 5, and a welding wire cutting mechanism 7. The bracket 102 is fixedly connected to the base 101. The pressing and positioning mechanism 3 is installed at the top of the bracket 102. The linear module 4 is fixedly connected to the front end of the bracket 102. The movable end of the linear module 4 is fixedly connected to one end of the support platform 103. The support platform 103 is fixedly connected to the laser welding device 5. The welding wire cutting mechanism 7 is fixedly connected to the front end of the support platform 103. The welding wire cutting mechanism 7 is used to cut the welding wire in the laser welding device 5.

[0031] A clamping and rotating mechanism 2 is installed on the base 101. The clamping and rotating mechanism 2 includes a supporting rotating component 21 and a pressing clamping and positioning component 22. The supporting rotating component 21 is installed on the base 101, and the pressing clamping and positioning component 22 is installed on the supporting rotating component 21.

[0032] The laser welding device 5 employs mature technologies in the field and consists of a welding head and a wire feeding tube, such as an automatic wire feeding laser welding machine.

[0033] In this invention, the operator or robotic arm places the T-pipe 8 on the supporting rotating assembly 21, and then places the welding pipe 9. During the pressing process, the pressing positioning mechanism 3 drives the welding pipe 9 and the T-pipe 8 to move downward, driving the pressing clamping positioning assembly 22 to clamp and limit the T-pipe 8. The linear module 4 is activated to align the welding end of the laser welding device 5 with the connection between the T-pipe 8 and the welding pipe 9. The laser welding device 5 is used, and the supporting rotating assembly 21 is activated simultaneously to completely weld the connection between the T-pipe 8 and the welding pipe 9. After welding is completed, the welding wire cutting mechanism 7 is used to trim the welding wire on the laser welding device 5 for the next welding.

[0034] In this invention, by adjusting the supporting rotating assembly 21, the pressing clamping and positioning assembly 22, and the pressing positioning mechanism 3, workpieces of different diameters are automatically calibrated, limited, and rotated, making it better suited for welding workpieces with arc-shaped bottoms; by adjusting the linear module 4, the welding end position of the laser welding device 5 is adjusted for workpieces of different lengths; the welding wire is trimmed by the welding wire cutting mechanism 7, so that when welding wire sticks, it will not affect the next welding, thus enhancing the stability of the welding.

[0035] like Figure 2 , Figure 3 and Figure 4 As shown, the supporting rotation assembly 21 includes a servo motor 211, a turntable 212, and a limiting ring 213; the turntable 212 is rotatably connected to the base 101, the lower plate of the base 101 is fixedly connected to the servo motor 211, and the output end of the servo motor 211 is fixedly connected to the turntable 212. The limiting ring 213 is fixedly connected to the turntable 212, and two symmetrical limiting grooves 214 are provided on the limiting ring 213 for initial limiting of the three-way pipe 8.

[0036] The downward clamping and positioning assembly 22 includes a Y-shaped clamping plate 222 and an L-shaped rotating plate 223. The limiting ring 213 has two symmetrical slots 221. The limiting ring 213 and the two symmetrical L-shaped rotating plates 223 are rotatably connected in the two slots 221 respectively. One end of the L-shaped rotating plate 223 is inside the limiting ring 213, and the other end of the L-shaped rotating plate 223 is outside the limiting ring 213. The other end of the L-shaped rotating plate 223 is fixedly connected to one end of the Y-shaped clamping plate 222, and the forked end of the Y-shaped clamping plate 222 points to the center of the limiting ring 213.

[0037] The pressing and positioning mechanism 3 includes a first push cylinder 31 and a positioning block 32; the first push cylinder 31 is rotatably connected to the top of the bracket 102 via a bearing, and the positioning block 32 is fixedly connected to the output shaft of the first push cylinder 31. The positioning block 32 is used to insert into the positioning groove 91 on the welded pipe 9.

[0038] In this utility model, the operator or robotic arm places the T-pipe 8 on the limiting ring 213, and initially limits the T-pipe 8 through the limiting groove 214. Then, the welding pipe 9 is placed, and the first push cylinder 31 is started. Driven by the output shaft of the first push cylinder 31, the positioning block 32 is inserted into the positioning groove 91 on the welding pipe 9. The positioning block 32 continues to move downward, driving the welding pipe 9 and the T-pipe 8 to move downward. At this time, the bottom of the T-pipe 8 contacts one end of the L-shaped rotating plate 223, causing the other end of the L-shaped rotating plate 223 to move towards the T-pipe 8, driving the Y-shaped clamp 222 to move towards the T-pipe 8 until the end of the Y-shaped clamp 222 limits the T-pipe 8. At this time, the T-pipe 8 and the welding pipe 9 are in a vertical state and completely limited. The servo motor 211 is started to drive the turntable 212 to rotate, so that the T-pipe 8 and the welding pipe 9 rotate synchronously with the cooperation of the pressing positioning mechanism 3.

[0039] In this utility model, the T-tube 8 is automatically limited by the limiting ring 213 and the pressing clamping positioning component 22. During the limiting process of the T-tube 8, the positioning block 32 is inserted into the positioning groove 91 on the welding pipe 9 to automatically align the welding pipe 9 with the T-tube 8, so that the T-tube 8 and the welding pipe 9 are automatically in a state ready for welding. The servo motor 211 and the turntable 212 make the T-tube 8 and the welding pipe 9 automatically rotate during the welding process to complete the welding.

[0040] like Figure 5 and Figure 6 As shown, the welding wire cutting mechanism 7 includes a cutting component and a driving component; the cutting component is installed at one end of the driving component near the laser welding device 5.

[0041] The drive assembly includes a second push cylinder 75, sliding rods 76, stop blocks 77, and baffles 78. The front end of the support platform 103 is fixedly connected to the rear end of the baffle 78. The end of the baffle 78 away from the laser welding device 5 is fixedly connected to the second push cylinder 75. The baffle 78 is slidably connected to two sliding rods 76. The two sliding rods 76 are located on the front and rear sides of the second push cylinder 75. One end of each sliding rod 76 is fixedly connected to two stop blocks 77. The stop blocks 77 are used to contact the baffle 78 to prevent the sliding rods 76 from continuing to move towards the laser welding device 5.

[0042] The shearing assembly includes a V-shaped blade 71, a first connecting block 72, a second connecting block 73, a spring 74, and a movable rod 79. The output shaft of the second push cylinder 75 is fixedly connected to the second connecting block 73, and the second connecting block 73 is fixedly connected to the two movable rods 79. Two movable slots 710 are opened at one end of the two V-shaped blades 71, and the two movable rods 79 are installed in the two movable slots 710. The two V-shaped blades 71 are rotatably connected at the inflection point by a rotating shaft. The other end of the two sliding rods 76 is fixedly connected to the first connecting block 72. The first connecting block 72 is fixedly connected to the rotating shaft of the two V-shaped blades 71 at the inflection point. The first connecting block 72 and the first connecting block 73 are respectively fixedly connected to both ends of the spring 74. The second connecting block 73 is located on the side of the first connecting block 72 away from the laser welding device 5.

[0043] In this invention, after welding is completed, the second push cylinder 75 is activated. The output shaft of the second push cylinder 75 drives the second connecting block 73 and the V-shaped blade 71 to move towards the laser welding device 5. Due to the action of the spring 74 and the V-shaped blade 71, the first connecting block 72, the sliding rod 76, and the stop block 77 move towards the laser welding device 5 until the stop block 77 and the baffle 78 contact each other. The sliding rod 76 and the first connecting block 72 stop moving. At this time, the connection inflection point of the two V-shaped blades 71 stops moving, but the second connecting block 73 continues to move under the drive of the output shaft of the second push cylinder 75. This causes the end of the two V-shaped blades 71 away from the laser welding device 5 to continue moving under the action of the movable groove 710. Since the two V-shaped blades 71 are rotatably connected, the end of the two V-shaped blades 71 close to the laser welding device 5 rotates inward to achieve shearing. After shearing, the blades are reset.

[0044] In this invention, the welding wire is automatically cut by the V-shaped blade 71, ensuring that the welding wire is in a normal state before each welding operation and enhancing the stability of the welding process.

[0045] The positioning block 32 is conical and is used to connect with the positioning groove 91 on the welded pipe 9.

[0046] The Y-shaped clamp 222 and the L-shaped rotating plate 223 are located on the outside of the moving end of the supporting rotating assembly 21, so that the Y-shaped clamp 222 and the L-shaped rotating plate 223 can maintain their tendency to move towards the outside of the moving end of the supporting rotating assembly 21 without external force.

[0047] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
