[0020] In order to more clearly understand the above-mentioned purpose, features and advantages of the utility model, the utility model is further described below in conjunction with the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0021] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0022] Embodiment 1

[0023] like Figure 1As shown in Figure 4, the utility model provides a small diameter pipe welding device, including a processing table 1 and two groups of laser welding guns 5. An elliptical hole 11 is penetrated in the middle of the processing table 1. A rotating mechanism 2 is arranged at the upper end of the processing table 1. The rotating mechanism 2 includes a circular ring seat 21 and a stepping motor 22. A gearbox 221 is fixedly installed at the lower end of the processing table 1. An outer gear ring 23 is arranged at one end of the circular ring seat 21. A limiting hole 24 is penetrated at one end of the circular ring seat 21. Two groups of fixed seats 25 are slidably installed inside the limiting hole 24. A driving gear 26 is fixedly installed at the output end of the gearbox 221. A connecting block 27 is welded at one end of the two groups of fixed seats 25. A plurality of sliding columns 29 are welded at one end of the outer gear ring 23. A circular groove 210 is opened at one end of the circular ring seat 21. The other ends of the two groups of connecting blocks 27 are fixed to one end of the outer gear ring 23, and several groups of sliding columns 29 are arranged inside the circular groove 210. The lower end of the circular ring seat 21 is arranged inside the elliptical hole 11. The driving gear 26 is meshed with the outer gear ring 23. Two groups of laser welding guns 5 are respectively installed in the middle of the two groups of fixed seats 25. The other end of the circular ring seat 21 and the positions near the front and rear edges are fixedly installed with L-shaped cylinders 28. Four groups of concave frames 211 are fixedly installed on the outer wall of the circular ring seat 21. The output end of the gearbox 221 is rotatably sleeved with a stabilizing seat, and the upper end of the stabilizing seat is fixed to the lower end of the processing table 1. The lower ends of the two groups of L-shaped cylinders 28 are fixed to the upper end of the processing table 1, and the openings of the four groups of concave frames 211 are aligned with the limiting holes 24.

[0024] The specific configuration and function of this embodiment are described in detail below. By providing a rotating mechanism 2, the stepper motor 22 is started, and the output end of the stepper motor 22 drives the gearbox 221 to operate. The cooperation between the stepper motor 22 and the gearbox 221 can more accurately control the rotation accuracy. The output end of the gearbox 221 drives the driving gear 26 fixed thereto to rotate. When the driving gear 26 is engaged with the outer gear ring 23, the driving gear 26 drives the outer gear ring 23 to rotate. At the same time, the outer gear ring 23 drives several groups of sliding posts 29 fixed thereto to rotate, so that the several groups of sliding posts 29 rotate inside the circular groove 210, which can increase the stability of the outer gear ring 23 when rotating, and Through the cooperation of the two groups of connecting blocks 27 and the two groups of fixing seats 25, the outer gear ring 23 can be limited so that one end of the outer gear ring 23 is always in contact with one end of the circular ring seat 21. Therefore, when the outer gear ring 23 moves, it will drive the two groups of fixing seats 25 to rotate through the two groups of connecting blocks 27, so that the two groups of fixing seats 25 are rotated inside the limiting holes 24, and the two groups of fixing seats 25 will drive the laser welding guns 5 fixed thereto to rotate together, so that the two groups of laser welding guns 5 are welded to the joints of the two small-diameter pipes. The steps of this welding process are not only simple, but also reduce the welding efficiency of the two small-diameter pipes and improve the welding efficiency of the two small-diameter pipes.

[0025] Embodiment 2

[0026] like Figure 1 and Figure 4 As shown, a moving mechanism 3 is provided at the upper end of the processing table 1 and near the edges on both sides. The moving mechanism 3 includes a No. 1 telescopic rod 31 and a push slide seat 32. Slide grooves 33 are provided at both ends of the upper end of the processing table 1 and near the upper and lower edges. The push slide seat 32 is placed on the upper end of the processing table 1, and two protrusions at the lower end of the push slide seat 32 are slidably installed in the two groups of slide grooves 33. One end of the No. 1 telescopic rod 31 is fixed to one end of the processing table 1, and the protruding end of the No. 1 telescopic rod 31 is fixed to one end of the push slide seat 32. The upper ends of the two groups of moving mechanisms 3 are provided with a fixing mechanism 4. The fixing mechanism 4 includes two groups of fixing blocks 41. One ends of the two groups of fixing blocks 41 are penetrated by a No. 2 telescopic rod 42. The protruding ends of the two groups of No. 2 telescopic rods 42 are fixedly installed with clamping recesses 43, and the lower ends of the two groups of fixing blocks 41 are fixed to the upper ends of the push slide seats 32.

[0027] The effect achieved by the entire embodiment is that, by setting up two groups of moving mechanisms 3 and two groups of fixing mechanisms 4, by manipulating one group of fixing mechanisms 4, the two No. 2 telescopic rods 42 are controlled to extend and retract, and the two No. 2 telescopic rods 42 will push the clamping recesses 43 fixed thereto to move, so that the two groups of clamping recesses 43 clamp the small-diameter pipe fittings between the two fixing blocks 41, and then repeat the above steps to control the operation of another group of fixing mechanisms 4 to clamp another small-diameter pipe fitting, so that the two small-diameter pipe fittings can be fixed, which is convenient for subsequent welding, and then one group of moving mechanisms 3 is manipulated to operate the No. 1 telescopic rod 31, and the No. 1 telescopic rod 31 is moved. The extended end of 31 pushes the push slide 32 to move, so that the two protruding parts at the lower end of the push slide 32 move inside the two slide grooves 33 respectively, increasing the stability of the push slide 32 and playing a guiding role at the same time, so that the push slide 32 drives the two fixed blocks 41 fixed thereto to move, and then facilitates the movement of one group of fixing mechanisms 4, and facilitates moving one group of fixing mechanisms 4 to the annular seat 21, and then controls the other group of moving mechanisms 3 to drive the other group of fixing mechanisms 4 to move, so as to facilitate the docking of two small-diameter pipes, thereby being able to move the two small-diameter pipes, and facilitating the laser welding gun 5 to weld the two small-diameter pipes.

[0028] The usage and working principle of this device are as follows: First, two groups of laser welding guns 5 are connected to an external welding machine and powered on. Then, one of the small-diameter pipe fittings is placed in the middle of one of the groups of fixing mechanisms 4. By controlling the operation of the two No. 2 telescopic rods 42, the clamping recess 43 fixed thereto is driven to move, so that the small-diameter pipe fitting can be fixed. Then, another small-diameter pipe fitting is placed in the middle of another group of fixing mechanisms 4. With the cooperation of the other group of fixing mechanisms 4, the other small-diameter pipe fitting can be fixed. Then, by starting and controlling the two groups of moving mechanisms 3, the No. 2 telescopic rod 42 pushes the push slide seat 32 fixed thereto to move. The two groups of push slide seats 32 respectively drive the fixing mechanisms 4 coordinated therewith to move, and the two groups of fixing mechanisms 4 can be brought to both sides of the circular ring seat 21, so that one end of the two small-diameter pipe fittings are moved to the middle of the circular ring seat 21 and connected to each other. Finally, the stepper motor 22 is started, and the output end of the stepper motor 22 drives the gearbox 221 to operate. The cooperation between the motor 22 and the gearbox 221 can more accurately control the rotation accuracy. The output end of the gearbox 221 will drive the driving gear 26 fixed thereto to rotate. Under the meshing of the driving gear 26 and the outer gear ring 23, the driving gear 26 will drive the outer gear ring 23 to rotate. At the same time, the outer gear ring 23 will drive several groups of sliding posts 29 fixed thereto to rotate, so that several groups of sliding posts 29 all rotate inside the circular groove 210, which can increase the stability of the outer gear ring 23 during rotation. Through the cooperation of the two groups of connecting blocks 27 and the two groups of fixing seats 25, the outer gear ring 23 can be limited, so that one end of the outer gear ring 23 is always in contact with one end of the circular ring seat 21. Therefore, when the outer gear ring 23 moves, it will drive the two groups of fixing seats 25 to rotate through the two groups of connecting blocks 27, so that the two groups of fixing seats 25 all rotate inside the limiting hole 24, and the two groups of fixing seats 25 will drive the laser welding guns 5 fixed thereto to rotate together, so that the two groups of laser welding guns 5 can weld the joints of the two small-diameter pipes.
