Detailed Implementation

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Reference Figures 1-3 This utility model provides an embodiment of an automatic welding rotary table for serpentine pipe elbows, comprising a base 1, a vertical plate 2 fixedly connected to the upper surface of the base 1, a boss 3 fixedly connected to the upper surface of the base 1, a rotating rod 4 rotatably connected to the side wall of the boss 3, and a rubber roller 5 fixedly connected to the outer wall of the rotating rod 4. The pipe elbow 6 can be rotated by the support of the boss 3 in conjunction with the rotating rod 4 and the rubber roller 5. Two sets of rotating rods 4 are provided, and the two sets of rotating rods 4 are mirror images of each other above the base 1 with the rotating shaft 74 as the central axis. The pipe elbow 6 is placed between the two sets of rotating rods 4. The pipe elbow 6 can be supported by the two sets of rotating rods 4 in conjunction with the rubber roller 5. At the same time, the pipe elbow 6 can be clamped at three points in conjunction with the rubber roller 75. The outer wall of the vertical plate 2 is provided with a driving mechanism 7 and a positioning mechanism 8.

[0019] Reference Figures 1-3 The drive mechanism 7 includes a slide table 71, which is slidably connected to the inner wall of the vertical plate 2. An electric push rod 72 is fixedly connected to the top of the vertical plate 2, and the output end of the electric push rod 72 is fixedly connected to the upper surface of the slide table 71. Activating the electric push rod 72 causes the slide table 71 to slide up and down along the inner wall of the vertical plate 2. Simultaneously, the slide table 71 moves up and down, causing the rotating shaft 74 to move up and down synchronously. A motor 73 is fixedly connected to the side wall of the slide table 71, and the output end of the motor 73 is fixedly connected to the rotating shaft 74, which passes through and... A rubber wheel 75 is fixedly connected to the outer wall of the rotating shaft 74, which is rotatably connected to the inner wall of the boss 3. Both the rubber wheel 75 and the rubber roller 5 are made of rubber. The excellent friction of the rubber can drive the rubber wheel 75 and the rubber roller 5 to rotate the bent pipe 6. The starting motor 73 drives the rotating shaft 74 to rotate. When the rotating shaft 74 rotates, it will drive the rubber wheel 75 to rotate synchronously. A welding part 76 is fixedly connected to the inner wall of the slide table 71. The welding part 76 is specifically a laser welding head. The bent pipe 6 is welded by laser welding.

[0020] Reference Figures 1-3 The positioning mechanism 8 includes an L-plate 81, which is slidably connected to the inner wall of the upright plate 2. A positioning rod 82 is slidably connected to the inner wall of the L-plate 81. A positioning plate 83 is fixedly connected to one end of the positioning rod 82 near the base 1. When the L-plate 81 slides, it can drive the positioning plate 83 to move synchronously in conjunction with the guide of the positioning rod 82 and the connection with the spring 84. The outer wall of the positioning rod 82 is fitted with a spring 84. The positioning plate 83 is elastically connected to the L-plate 81 through the spring 84. The elasticity of the spring 84 allows the positioning plate 83 to press against the outer wall of the bent pipe 6, and it can axially limit the bent pipe 6 of different lengths. Both sides of the slide table 71 are fixedly connected with crossbars 85. The end of the crossbar 85 away from the slide table 71 is hinged to a connecting rod 86. The end of the connecting rod 86 away from the crossbar 85 is hinged to the outer wall of the L plate 81. While the slide table 71 slides on the inner wall of the vertical plate 2, it can push the L plate 81 in conjunction with the crossbar 85 and the connecting rod 86, so that the L plate 81 slides on the inner wall of the boss 3.

[0021] Working principle: Place the two bent pipe fittings 6 to be welded between the two sets of rubber rollers 5, and make the welding ends of the two bent pipe fittings 6 fit together. Then, start the electric push rod 72 to drive the slide table 71 to slide downward on the inner wall of the vertical plate 2. As the slide table 71 slides downward, it will drive the rotating shaft 74 to move downward synchronously until the rubber wheel 75 on the outer wall of the rotating shaft 74 presses the bent pipe fittings 6 against the outer wall of the rubber rollers 5. Then, close the electric push rod 72. At this time, the rubber wheel 75 and the two sets of rubber rollers 5 can limit the radial movement of the two bent pipe fittings 6. Then, start the motor 73 to drive the rotating shaft 74 to rotate. As the rotating shaft 74 rotates, it will drive the rollers 74 to move downward. The rubber wheel 75 rotates synchronously. At the same time, since the rubber wheel 75 presses the bent pipe part 6 against the outer wall of the rubber roller 5, the rubber wheel 75 will drive the bent pipe part 6 to rotate synchronously while rotating. The bent pipe part 6 will drive the rubber roller 5 to rotate, so that the rubber roller 5 will drive the rotating rod 4 to rotate on the inner wall of the boss 3. While the bent pipe part 6 is rotating, the welding part 76 can be started to perform welding operations on the welding ends of the two sets of bent pipe parts 6. Furthermore, the rotation of the bent pipe part 6 can complete the welding of a whole circle of the bent pipe part 6 in one go, making the welding of the bent pipe part 6 more convenient and improving the welding efficiency of the workpiece.

[0022] As the slide table 71 slides downward on the inner wall of the vertical plate 2, it drives the crossbar 85 to slide downward simultaneously. As the crossbar 85 slides downward, it pushes the connecting rod 86, causing the connecting rod 86 to push the L plate 81. At this time, the L plate 81 slides on the inner wall of the boss 3. While the L plate 81 is sliding, it can drive the positioning plate 83 to move synchronously in conjunction with the guide of the positioning rod 82 and the connection of the spring 84. This allows the positioning plate 83 to gradually approach the bent pipe 6. When the positioning plate 83 contacts the bent pipe 6 during its movement, it pushes the bent pipe 6, causing the two sets of bent pipe 6 to press against each other. This can limit the axial movement of the bent pipe 6, allowing the welded ends of the two sets of bent pipe 6 to fit together stably, which is beneficial to improving the welding quality of the bent pipe 6.

[0023] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
