[0039] like Figure 1-4As shown, the present invention provides a welding system for the outer girder of a short cylinder of a stainless steel tank, comprising: an inner support component 1 and an outer pressure component 2. The inner support component 1 comprises an inner support circular component, and the inner support circular component comprises a disc base 1-1. The disc base 1-1 is provided with a plurality of inner support mechanisms along its circumferential direction. The inner support mechanism is movably arranged along the radial direction of the disc base 1-1, so as to move toward or away from the short cylinder, and to support the short cylinder from the inside of the short cylinder. The end face of the inner support mechanism for contacting the short cylinder is a profile that matches the inner side surface of the short cylinder. The outer pressure component 2 is used to press the girder to the outer side surface of the short cylinder from the outside of the short cylinder, so as to weld the short cylinder and the girder.

[0040] The welding system of this embodiment rounds and fixes the short cylinder inside the short cylinder by the inner supporting mechanism of the rounding supporting component, and presses the stringer to the outer side of the short cylinder by the outer pressing component 2 outside the short cylinder to weld the short cylinder and the stringer. The welding system can ensure that the welding position of the tank short cylinder does not shift during the whole welding process, thereby improving the welding accuracy and welding quality.

[0041] like Figure 2 As shown, according to one embodiment of the present invention, the inner support mechanism includes an inner support guide rod 1-2 and an inner support plate 1-3 arranged along the radial direction of the short cylinder. The inner support guide rod 1-2 is movably arranged along the radial direction of the disc base 1-1. The inner support plate 1-3 is connected to the inner support guide rod 1-2. The inner support guide rod 1-2 moves along the radial direction of the disc base 1-1, driving the inner support plate 1-3 to approach or move away from the short cylinder.

[0042] The welding system of this embodiment is convenient for loading and unloading the short cylinder by setting a retractable inner support mechanism. For example, a plurality of linear guide rails are set along the circumferential direction of the disc base 1-1, and the inner support guide rod 1-2 is fixedly connected to the slider of the linear guide rail. The slider drives the inner support guide rod 1-2 to move along the radial direction of the disc base 1-1, so that the inner support plate 1-3 supports the short cylinder from the inside.

[0043] Furthermore, when the inner support mechanism supports the inner side surface of the short tube, the inner support plates 1-3 of the multiple inner support mechanisms are spliced ​​to form a full circle that matches the inner side surface of the short tube, further ensuring the shape accuracy of the short tube.

[0044] like Figure 5 and 6As shown, according to one embodiment of the present invention, in addition to the disc base 1-1, the inner support circular component also includes a guide drive component. The guide drive component includes a guide disc 1-7. The guide disc 1-7 is arranged on the disc base 1-1 and is rotatable relative to the disc base 1-1. The guide disc 1-7 is provided with a plurality of guide grooves 1-8 corresponding to the inner support mechanism along its circumferential direction. Along the circumferential direction of the guide disc 1-7, the distance between the guide groove 1-8 and the center of the guide disc 1-7 becomes larger. A guide column 1-9 is provided on the side of the inner support guide rod 1-2 close to the guide disc 1-7, one end of the guide column 1-9 is provided in the guide groove 1-8, and the guide column 1-9 is slidably provided relative to the guide groove 1-8. Through the rotation of the guide disc 1-7 relative to the disc base 1-1, the guide groove 1-8 drives the guide column 1-9 to move along the radial direction of the disc base 1-1.

[0045] In an embodiment, for example, the guide groove 1-8 extends along the circumferential direction of the guide disc 1-7, and is an arc extending toward the circumferential side of the guide disc 1-7. The inner support guide rod 1-2 is limited in the circumferential direction of the disc base 1-1 (i.e., the inner support guide rod can only move in the radial direction of the disc base when an external force is applied). The guide disc 1-7 rotates relative to the disc base 1-1, and the guide groove 1-8 moves. By positioning the guide column 1-9, the guide column drives the inner support guide rod 1-2 to move in the radial direction of the disc base 1-1, thereby realizing the extension and retraction of the inner support guide rod 1-2 relative to the disc base 1-1.

[0046] like Figure 7 As shown, according to one embodiment of the present invention, the disc base 1-1 can be provided with a driving gear 1-13. The driving gear 1-13 is meshed with the guide disc 1-7, and the guide disc 1-7 is driven to rotate relative to the disc base 1-1 by the rotation of the driving gear 1-13.

[0047] In this embodiment, for example, the driving gear 1-13 is connected to a motor. When the motor is started, the driving gear 1-13 drives the guide disc 1-7 to rotate.

[0048] like Figure 1 As shown, according to one embodiment of the present invention, a plurality of inner supporting circular parts are arranged along the axial direction (ie, the direction perpendicular to the disc base 1-1), and a plurality of inner supporting circular columns 1-4 are arranged between two adjacent inner supporting circular parts to support the inner supporting circular parts.

[0049] In this embodiment, a plurality of inner supporting circular members (for example, three inner supporting circular members) simultaneously support the inner side surface of the short tube from the inside of the short tube along the axial direction of the short tube, which can improve the shape accuracy of the short tube.

[0050] like Figure 8As shown, according to one embodiment of the present invention, in addition to the inner supporting circular member, the inner supporting member 1 also includes a rotating mechanism. The rotating mechanism includes a rotating mechanism base 1-5 and a driven gear 1-6, and the driven gear 1-6 is used to support the disc base 1-1 and the bottom of the short cylinder. The driven gear 1-6 is rotatably arranged relative to the rotating mechanism base 1-5 to drive the disc base 1-1 and the short cylinder to rotate.

[0051] The welding system of this embodiment can control the welding position of the beam on the outer side of the short tube by driving the disc base 1-1 and the short tube to rotate through the driven gear 1-6. For example, the rotating mechanism can also include a driving gear 1-14, and the driving gear 1-14 is meshed with the driven gear 1-14. The driving gear 1-14 can be connected to a motor. The motor starts and drives the driving gear 1-14 to drive the driven gear 1-6 to rotate.

[0052] like Figure 1 As shown, according to one embodiment of the present invention, in addition to the inner support circular component, the inner support component 1 also includes an inner support column 1-10 and a column inner support mechanism. The inner support column 1-10 is used to be placed inside the short tube, and the column inner support mechanism is arranged on the circumferential side of the inner support column 1-10. The column inner support mechanism includes an inner support column driving cylinder 1-11 and a column inner support plate 1-12 arranged along the radial direction of the disc base 1-1 (i.e., perpendicular to the axial direction of the inner support column 1-10), and the column inner support plate 1-12 is connected to the telescopic rod of the inner support column driving cylinder 1-11. By extending and retracting the telescopic rod of the inner support column driving cylinder 1-11, the column inner support plate 1-12 is driven toward or away from the inner side surface of the short tube, so that the column inner support plate 1-12 supports or releases the inner side surface of the short tube.

[0053] In this embodiment, the column inner support plate 1-12 is used to support the welding position of the truss and the short tube. For example, the inner support column 1-10 can be set in the middle of the disc base 1-1 and perpendicular to the disc base 1-1. The disc base 1-1, the guide disc 1-7, the rotating mechanism base 1-5, and the driven gear 1-6 are rotatably connected or gap-set relative to the inner support column 1-10. That is, when the rotating mechanism drives the disc base 1-1 and the short tube to rotate, the inner support column 1-10 and the column inner support mechanism do not rotate accordingly. For example, a group of column inner support mechanisms are set between two adjacent inner support circular parts.

[0054] According to one embodiment of the present invention, for example, the lower end of the inner support column 1-10 can be connected to the ground or to a device fixed on the ground (for example, Figure 8 The inner support base 1-15) shown is fixedly connected.

[0055] like Figure 3 and 4As shown, according to one embodiment of the present invention, the external pressure component 2 includes an external pressure column 2-1 and a clamping component. The clamping component is arranged on the side of the external pressure column 2-1. The clamping component is used to clamp the beam and press the beam to the outer side of the short tube.

[0056] In this embodiment, the external pressure component 2 is used to clamp the stringers outside the short tube and press them to the outer side surface of the short tube to weld the stringers.

[0057] According to one embodiment of the present invention, in addition to the external pressure column 2-1 and the clamping component, the external pressure component 2 further includes a linear guide rail. The linear guide rail can be fixedly arranged on the ground or arranged on a device fixed on the ground, and the linear guide rail is arranged along the radial direction of the short cylinder. The external pressure column 2-1 can be slidably arranged relative to the linear guide rail to drive the clamping component to approach or move away from the cylinder. For example, the clamping component can be a device similar to a gripper, etc.

[0058] like Figure 3 and 4 As shown, according to one embodiment of the present invention, a support 2-2 is provided on the side of the external pressure column 2-1 facing the short cylinder, and a support plate 2-3 is provided on the two opposite sides of the support 2-2. The support plate 2-3 is provided with a clamping slider 2-4 that can slide relative to it. The clamping component includes a clamping drive cylinder 2-5, two pull rods 2-6 and two clamping arms 2-7. The clamping drive cylinder 2-5 is arranged along the height direction of the external pressure column 2-1. The telescopic rod of the clamping drive cylinder 2-5 penetrates the support 2-2 and is slidably arranged relative to the support 2-2. One end of the pull rod 2-6 is rotatably connected to the circumferential side of the telescopic rod of the clamping drive cylinder 2-5. The other end of the pull rod 2-6 is rotatably connected to the clamping slider 2-4. The side of the clamping slider 2-4 relative to the short cylinder is connected to one end of the clamping arm 2-7. By extending and retracting the telescopic rod of the clamping drive cylinder 2-5, one end of the pull rod 2-6 is driven to move up and down, so that the other end of the pull rod 2-6 drives the two clamping sliders 2-4 to move closer to or away from each other, so that the other ends of the two clamping arms 2-7 move closer to or away from each other to clamp or release the beam.

[0059] In this embodiment, one end of the pull rod 2-6 moves up and down, which drives the clamping slide block 2-4 connected to the other end of the pull rod 2-6 to slide relative to the support plate 2-3. For example, the two clamping arms 2-7 are arranged in parallel on a horizontal plane.

[0060] like Fig. 9 As shown, according to one embodiment of the present invention, for example, the vertical cross section of the clamping slide block 2-4 can be an I-shaped. The support plate 2-3 is provided with a clamping guide groove 2-11, and the clamping slide block 2-4 is slidably arranged relative to the clamping guide groove 2-11.

[0061] In this embodiment, the clamping slider 2-4 is designed to be I-shaped, and cooperates with the support plate 2-3 to limit the clamping slider 2-4 in the height direction and slide it in the horizontal direction.

[0062] like Fig.10 As shown, according to one embodiment of the present invention, for example, two corresponding support arms 2-12 are provided on the circumferential side wall of the telescopic rod of the clamping drive cylinder 2-5. A rotating shaft 2-13 is provided at one end of the two support arms 2-12 away from the telescopic rod of the clamping drive cylinder 2-5. One end of the pull rod 2-6 is rotatably connected to the rotating shaft 2-13.

[0063] like Figure 3 and 4 As shown, according to one embodiment of the present invention, the external pressure column 2-1 is provided with a plurality of supports 2-2 along its height direction. The circumferential side surface of the telescopic rod of the clamping drive cylinder is provided with a plurality of groups of pull rods 2-6 and clamp arms 2-7 corresponding to the supports 2-2.

[0064] In this embodiment, the telescopic rod of the clamping drive cylinder 2-5 passes through the multiple supports 2-2 in sequence and can slide relative to the multiple supports 2-2. The telescopic rod of the clamping drive cylinder 2-5 is extended and retracted, driving one end of the multiple groups of pull rods 2-6 to move up and down at the same time, so as to drive the multiple groups of clamping arms 2-7 to clamp or release the beams at the same time along the length direction of the beams, thereby ensuring the stability of the beams and the welding quality during the welding process.

[0065] like Fig.11 As shown, according to one embodiment of the present invention, in addition to the inner support component 1 and the external pressure component 2, the welding system also includes a welding component 3. A top plate 2-8 and a bottom plate 2-9 extending toward the short tube are respectively arranged at both ends of the external pressure column 2-1. A welding column 2-10 is arranged between the top plate 2-8 and the bottom plate 2-9. The welding component 3 is slidably arranged relative to the welding column 2-10 along its height direction to weld the entire stringer.

[0066] In this embodiment, the welding component 3 moves up and down relative to the welding column 2-10, so that the welding head of the welding component 3 can weld the stringer along the length direction of the stringer (for example, laser welding). For example, the bottom plate 2-9 can be slidably arranged with a linear guide rail arranged on the ground, so that the external pressure component is close to or away from the welding position of the stringer and the short tube.

[0067] like Fig.12 As shown, according to one embodiment of the present invention, the external pressure column 2-1 is provided with a screw rod along its height direction (i.e., the axial direction of the short cylinder). The welding component 3 includes a Z-axis slider 3-1, and the welding head 3-2 is provided on the Z-axis slider 3-1. The Z-axis slider 3-1 is slidably provided relative to the screw rod to drive the welding head 3-2 to move up and down (in the Z-axis direction).

[0068] According to one embodiment of the present invention, a Y-axis slider 3-3 is disposed on the Z-axis slider 3-1, and the welding head is disposed on the Y-axis slider 3-3. In the horizontal direction, the Y-axis slider 3-3 can slide relative to the Z-axis slider 3-1 along the vertical direction (Y-axis direction) of the short cylinder radial direction to drive the welding head 3-2 to move horizontally.

[0069] According to one embodiment of the present invention, an X-axis slider 3-4 is arranged on the Y-axis slider 3-3, and the welding head 3-2 is fixedly arranged with the X-axis slider 3-4. In the horizontal direction, the X-axis slider 3-4 can slide relative to the Y-axis slider 3-3 along the radial direction (X-axis direction) of the short tube, so as to move toward or away from the welding position of the stringer and the short tube.

[0070] In this embodiment, the Z-axis direction is the vertical direction. In the horizontal direction, the X-axis direction is perpendicular to the Y-axis direction, and the Z-axis direction is perpendicular to the X-axis direction and the Y-axis direction.
