[0056] like Figure 1-4 As shown, the present invention provides a welding system for the outer stringers of the barrel section of a stainless steel rocket tank, comprising: an inner support component 2 and an outer pressure component 1. The inner support component 2 comprises a rounding component 2-1, which is used to round the barrel section from the inside of the barrel section. The end surface of the rounding component 2-1 used to contact the barrel section is a profile that matches the inner side surface of the barrel section. The outer pressure component 1 is used to press the stringers to the outer side surface of the barrel section outside the barrel section to weld the barrel section and the stringers.

[0057] In this embodiment, the rounding component 2-1 is used to round and fix the cylinder segment inside the cylinder segment, and the external pressure component 1 is used to press the stringer to the outer side of the cylinder segment outside the cylinder segment, so as to achieve welding of the stringer to the outer side of the cylinder segment and ensure that the welding position of the cylinder segment or short cylinder does not shift during the entire welding process. The welding system can ensure the shape of the cylinder segment and does not require strict cleaning of welding spatter dust.

[0058] like Figure 5-7 As shown, according to one embodiment of the present invention, the circular support component 2-1 includes an inner circular support component. The inner circular support component includes a disc base 2-1-4-1, and the disc base 2-1-4-1 is provided with a plurality of inner support mechanisms 2-1-4-3 along its circumferential direction. The inner support mechanism 2-1-4-3 includes an inner support drive cylinder 2-1-4-3-2 and an inner support plate 2-1-4-3-3 arranged along the radial direction of the barrel section, and the inner support plate 2-1-4-3-3 is connected to the telescopic rod of the inner support drive cylinder 2-1-4-3-2. The inner support plate 2-1-4-3-3 is driven to approach or move away from the barrel section by the telescopic rod of the inner support drive cylinder 2-1-4-3-2.

[0059] In this embodiment, the inner support mechanism 2-1-4-3 is used to support the cylindrical section. The inner support plate 2-1-4-3-3 is used to contact the arc end surface of the cylindrical section and has the same inner diameter as the inner side surface of the cylindrical section to better fit the inner side surface of the cylindrical section. The inner support plate 2-1-4-3-3 can be made of brass or copper. For example, Figure 6 As shown, the disc base 2-1-4-1 is provided with 12 inner support mechanisms 2-1-4-3 along its circumferential direction. The inner support drive cylinder 2-1-4-3-2 can be an electric cylinder, a hydraulic cylinder, etc. The welding system can make the shape tolerance of the short cylinder controllable.

[0060] For example, when the inner support plates 2-1-4-3-3 are located at the station for tightening the short cylinder, multiple inner support plates 2-1-4-3-3 can be spliced ​​to form a full circle that matches the inner side surface of the cylinder section to control the shape accuracy of the short cylinder.

[0061] For example, the internal support mechanism includes a plurality of first internal support mechanisms and a plurality of second internal support mechanisms, and the first internal support mechanisms and the second internal support mechanisms are arranged at intervals. When the internal support mechanism is in a state of supporting the short tube in a round shape, the internal support plates of the first internal support mechanism and the second internal support mechanism are spliced ​​to form a whole circle that matches the inner side surface of the short tube. When the internal support mechanism is not needed to support the short tube in a round shape, the telescopic rod of the internal support drive cylinder of the second internal support mechanism is retracted first, and then the telescopic rod of the internal support drive cylinder of the first internal support mechanism is retracted, and the retraction degree (or retraction distance) of the telescopic rod of the internal support drive cylinder of the second internal support mechanism is greater than the retraction degree (or retraction distance) of the telescopic rod of the internal support drive cylinder of the first internal support mechanism.

[0062] like Figure 6 As shown, according to one embodiment of the present invention, a copper support plate 2-1-4-2 is provided on the circumferential outer side of the disc base 2-1-4-1.

[0063] In this embodiment, for example, the copper support plate 2-1-4-2 can be a long copper plate, wrapped around the circumferential outer side of the disc base 2-1-4-1. The copper support plate 2-1-4-2 and the disc base 2-1-4-1 can be locked by screws or the like so that the two fit tightly.

[0064] like Figure 7As shown, according to one embodiment of the present invention, in addition to the inner support drive cylinder 2-1-4-3-2 and the inner support plate 2-1-4-3-3, the inner support mechanism 2-1-4-3 also includes an inner support circle linear guide rail 2-1-4-3-1 and an adapter block 2-1-4-3-5. The inner support drive cylinder 2-1-4-3-2 is arranged on the inner support circle linear guide rail 2-1-4-3-1, and the inner support plate 2-1-4-3-3 is connected to the telescopic rod of the inner support drive cylinder 2-1-4-3-2 through the adapter block 2-1-4-3-5. The adapter block 2-1-4-3-5 is slidably arranged relative to the inner support circle linear guide rail 2-1-4-3-1 to drive the inner support plate 2-1-4-3-3 to approach or move away from the barrel section.

[0065] In this embodiment, the inner circular linear guide rail 2-1-4-3-1 is arranged along the radial direction of the disc base 2-1-4-1. For example, the inner circular linear guide rail 2-1-4-3-1 and the disc base 2-1-4-1 and the disc base 2-1-4-1 can be locked and fixed by screws or the like.

[0066] According to an embodiment of the present invention, support plates 2-1-4-3-4 fixedly connected to the inner support plate 2-1-4-3-3 are respectively provided on both sides (left and right sides) of the adapter block 2-1-4-3-5. The support plate 2-1-4-3-4 is used to support the inner support plate 2-1-4-3-3 to prevent the inner support plate 2-1-4-3-3 from deforming when tightening the short cylinder.

[0067] In this embodiment, for example, the support plate 2-1-4-3-4 and the adapter block 2-1-4-3-5 and the inner support plate 2-1-4-3-3 can be locked and fixed by means of screws or the like.

[0068] like Figure 5 As shown, according to one embodiment of the present invention, a plurality of inner supporting circular parts are arranged along the axial direction of the barrel section, and a plurality of inner supporting circular columns 2-1-6 are arranged between two adjacent inner supporting circular parts to support the inner supporting circular parts.

[0069] In this embodiment, for example, Figure 5 As shown, three inner supporting circular parts (2-1-7, 2-1-4, 2-1-5 from bottom to top) are arranged along the axial direction of the barrel section, and the structures of the three inner supporting circular parts are the same or substantially the same, so as to better support and fix the barrel section.

[0070] like Figure 6 As shown, according to one embodiment of the present invention, the inner supporting circular component (2-1-7, 2-1-4) is provided with a column mounting seat 2-1-4-4, and the column mounting seat 2-1-4-4 is used to install the inner supporting circular column 2-1-6 to support the inner supporting circular component (2-1-4, 2-1-5) above it.

[0071] In this embodiment, for example, the disc base 2-1-4-1 is provided with six inner supporting circular columns 2-1-6 along its circumferential direction. The column mounting seat 2-1-4-4 and the inner supporting circular columns 2-1-6 can be locked and fixed by bolts or welding.

[0072] like Figure 8 As shown, a plurality of guide blocks 2-1-5-4 are also provided along the circumferential direction of the inner supporting circular component 2-1-5 near the top end of the short cylinder, and the guide blocks 2-1-5-4 are used to guide the short cylinder to be sleeved on the supporting circular component 2-1.

[0073] In this embodiment, the guide block 2-1-5-4 is used to guide the short cylinder sleeved on the supporting circular component 2-1, so as to facilitate the loading and unloading of the short cylinder. For example, the guide block 2-1-5-4 can be arranged on the inner supporting mechanism of the inner supporting circular component 2-1-5 near the top of the short cylinder. For example, the disc base of the inner supporting circular component 2-1-5 near the top of the short cylinder is provided with 12 guide blocks 2-1-5-4 along its circumferential direction.

[0074] like Figure 5 and 9 As shown, according to one embodiment of the present invention, in addition to the inner supporting circular member, the supporting circular member 2-1 also includes a rotating mechanism 2-1-3. The inner supporting circular member 2-1 is arranged on the rotating mechanism 2-1-3. The rotating mechanism 2-1-3 includes a rotating mechanism base 2-1-3-1 and a driven gear 2-1-3-2, and the driven gear 2-1-3-2 is rotatably arranged relative to the rotating mechanism base 2-1-3-1 to drive the inner supporting circular member 2-1 and the barrel section to rotate.

[0075] In this embodiment, for example, the disc base of the lowest inner supporting circular component 2-1-7 can be fixed to the driven gear 2-1-3-2 by screws to drive the inner supporting circular component 2-1-7 to rotate.

[0076] Furthermore, the inner support component 2 may also include an inner support base 2-1-1. The inner support base 2-1-1 is provided with a plurality of base columns 2-1-2 along its circumferential direction (for example, six base columns 2-1-2 are provided). The rotating mechanism 2-1-3 is provided on the base column 2-1-2, for example, the rotating mechanism base 2-1-3-1 is supported by the base column 2-1-2. The rotating mechanism 2-1-3 and the base column 2-1-2 may be fixedly connected by bolts, for example, the rotating mechanism base 2-1-3-1 and the base column 2-1-2 are fixedly connected by bolts.

[0077] According to one embodiment of the present invention, in addition to the rotating mechanism base 2-1-3-1 and the driven gear 2-1-3-2, the rotating mechanism 2-1-3 also includes a gear drive motor 2-1-3-3 and a drive gear 2-1-3-4. The drive gear 2-1-3-4 is meshed with the driven gear 2-1-3-2, and the gear drive motor 2-1-3-3 and the drive gear 2-1-3-4 are fixedly connected. The gear drive motor 2-1-3-3 is started, and by driving the drive gear 2-1-3-4, the driven gear 2-1-3-2 is driven to rotate relative to the rotating mechanism base 2-1-3-1.

[0078] In this embodiment, the driving gear 2-1-3-4 is connected to the rotor of the gear driving motor 2-1-3-3. For example, the gear driving motor 2-1-3-3 can be installed on the rotating mechanism base 2-1-3-1 and fixed by bolts. The welding system can drive the inner support circular component 2-1 and the barrel section to rotate and position through the gear driving motor 2-1-3-3 and the rotatable driven gear 2-1-3-2 to accurately control the welding position of the stringer on the short barrel.

[0079] Furthermore, the rotating mechanism 2-1-3 also includes a boss 2-1-3-5. The boss 2-1-3-5 is sleeved on the circumferential outer side surface of the driven gear 2-1-3-2 to protect the driven gear 2-1-3-2.

[0080] In this embodiment, the boss 2-1-3-5 is fixedly arranged on the rotating mechanism base 2-1-3-1, and the boss 2-1-3-5 and the driven gear 2-1-3-2 are set with a gap. For example, the boss 2-1-3-5 can be fixed to the rotating mechanism base 2-1-3-1 by screws, etc. The outer diameter of the boss 2-1-3-5 is slightly smaller than the outer diameter of the supporting round short cylinder to provide operating space for the external pressure component 1.

[0081] like Figure 4 and 10 As shown, according to one embodiment of the present invention, in addition to the supporting circular component 2-1, the inner support component 2 also includes an inner support column component 2-2. The inner support column component 2-2 is used to be placed inside the barrel section. The inner support column component 2-2 includes an inner support column 2-2-3 and a column inner support mechanism 2-2-4, and the column inner support mechanism 2-2-4 is arranged on the side of the inner support column 2-2-3. The column inner support mechanism 2-2-4 includes an inner support column driving cylinder 2-2-3-2 and a column inner support plate 2-2-3-3 arranged along the radial direction of the barrel section, and the column inner support plate 2-2-3-3 is connected to the telescopic rod of the inner support column driving cylinder 2-2-3-2. The telescopic rod of the inner support column driving cylinder 2-2-3-2 is extended and retracted to drive the column inner support plate 2-2-3-3 toward or away from the inner side surface of the barrel section, so that the column inner support plate 2-2-3-3 supports or releases the inner side surface of the barrel section.

[0082] In this embodiment, when welding the truss, the inner support column component 2-2 can tighten the welding position from the inner side of the barrel section, and cooperate with the inner support circular component (in the supporting circular state) to form an inner support cylindrical surface for truss welding, thereby ensuring welding accuracy and welding quality, and ensuring the stability of weld quality. For example, multiple groups of column inner support mechanisms 2-2-4 (for example, two groups of column inner support mechanisms 2-2-4) are arranged along the axial direction of the barrel section (i.e., the height direction of the inner support column 2-2-3). A gap is left between two adjacent groups of column inner support mechanisms 2-2-4 to provide installation space and operation space for the inner support circular component. For example, the column inner support plate 2-2-3-3 can be made of red copper, which can prevent the barrel section from being welded on the inner support component.

[0083] According to one embodiment of the present invention, along the height direction of the inner support column 2-2-3, (each group) of the column inner support mechanism 2-2-4 can be provided with a plurality of inner support column driving cylinders 2-2-3-2 (for example, three inner support column driving cylinders 2-2-3-2 are provided), and the plurality of inner support column driving cylinders 2-2-3-2 jointly control the column inner support plate 2-2-3-3 to approach or move away from the barrel section.

[0084] According to one embodiment of the present invention, in addition to the inner support column driving cylinder 2-2-3-2 and the column inner support plate 2-2-3-3, the column inner support mechanism 2-2-4 includes a column inner support base 2-2-3-1 arranged on the side of the inner support column 2-2-3.

The inner support column linear guide rail 2-2-2 is arranged along the radial direction of the barrel section, and the inner support column 2-2-3 is slidably arranged relative to the inner support column linear guide rail 2-2-2.

[0086] In this embodiment, the inner support column 2-2-3 slides relative to the inner support column linear guide rail 2-2-2, and can make room when the circular support component 2-1 rotates to avoid interference between the inner support column 2-2-3 and the circular support component 2-1. For example, the inner support column 2-2-3 can be fixedly mounted on the slider of the inner support column linear guide rail 2-2-2.

[0087] Furthermore, the inner support column 2-2-3 can be arranged on the inner support column base 2-2-1.

[0088] In this embodiment, for example, the inner support base 2-1-1 can be arranged on the inner support column base 2-2-1 and fixed by bolts. The inner support base 2-1-1 is a ring structure, and the inner support column 2-2-3 or the inner support column linear guide 2-2-2 is arranged on the inner support column base 2-2-1 through the hollow part of the inner support base 2-1-1. For example, the inner support column base 2-2-1 can be fixed to the ground by bolts. The inner support column linear guide 2-2-2 and the inner support column base 2-2-1 are fixed by screws or the like.

The beam positioning component is arranged on the side of the external pressure column 1-2. The beam positioning component includes an external clamping drive cylinder 1-4-5 and an external clamping block 1-4-2 arranged along the radial direction of the barrel section, and the external clamping block 1-4-2 is connected to the telescopic rod of the external clamping drive cylinder 1-4-5. The external clamping block 1-4-2 is driven toward or away from the beam on the outer side surface of the barrel section by telescoping the telescopic rod of the external clamping drive cylinder 1-4-5, so as to press the beam to the outer side surface of the barrel section or release the beam.

[0090] In this embodiment, for example, the external pressing drive cylinder 1-4-5 can be a cylinder, etc. The external pressing drive cylinder 1-4-5 can be installed on the external pressing column 1-2. The welding system can press the stringer to the outer side of the barrel section through the external pressing component 1, thereby realizing the positioning and welding of the stringer.

[0092] In this embodiment, the external pressure linear guide rail 1-7 can be arranged along the radial direction of the barrel section.

[0093] Furthermore, the external pressure component 1 further includes an external pressure base 1-1. The external pressure base 1-1 is arranged on the external pressure linear guide rail 1-7.

[0094] like Fig.12 and 13 As shown, according to one embodiment of the present invention, the external pressure column 1-2 is provided with a lift 1-3. The lift 1-3 can be lifted and lowered along the height direction of the external pressure column 1-2.

[0095] In this embodiment, the lift 1-3 facilitates the production personnel to install the stringers.

The elevator guide rail 1-3-1 is provided with the passenger ladder 1-3-2.

[0097] In this embodiment, for example, the passenger escalator 1-3-2 is slidably arranged along the lifting rail 1-3-1 to achieve lifting. Alternatively, the lifting rail 1-3-1 is slidably arranged along the external pressure column 1-2 and is fixedly arranged with the passenger escalator 1-3-2 to drive the passenger escalator 1-3-2 to lift and lower.

The telescopic rod of the beam end clamping drive cylinder 1-4-3 is extended and retracted to drive the internal positioning block 1-4-1 toward or away from the end of the beam, so as to clamp or release the beam from the end in the length direction of the beam.

[0099] In this embodiment, the outer clamping block 1-4-2 cooperates with the inner positioning block 1-4-1 to clamp the beam. For example, the beam end clamping drive cylinder 1-4-3 can be an electric cylinder or the like.

[0101] In this embodiment, the inner positioning blocks 1-4-1 of the upper beam positioning component 1-4 and the lower beam positioning component 1-5 are arranged opposite to each other and may have the same or substantially the same structure. The upper beam positioning component 1-4 and the lower beam positioning component 1-5 respectively press or release the beam from the upper end and the lower end of the beam along the axial direction of the beam to dock the beam with the short tube. For example, the upper beam positioning component 1-4 and the lower beam positioning component 1-5 may be locked and fixed with the external pressure column 1-2 by bolts.

[0102] like Figure 14-17As shown, according to one embodiment of the present invention, an inner positioning quick-insert hole 1-4-1-4 is provided on the end surface of the telescopic rod of the inner positioning block 1-4-1 connected to the end of the beam pressing drive cylinder 1-4-3.

For example, the end surface of the inner positioning block 1-4-1 used for butting the end of the beam is the inner positioning trapezoidal imitation inner wall 1-4-1-3. The inner positioning trapezoidal imitation inner wall 1-4-1-3 is a trapezoidal surface or a rectangular surface.

[0108] In this embodiment, the external pressure quick plug hole 1-4-2-2 is used to realize the quick connection between the external pressure block 1-4-2 and the telescopic rod of the external pressure drive cylinder 1-4-5 or to replace the external pressure block 1-4-2.

[0111] The welding system of this embodiment can better wrap the trusses and clamp and fix the trusses.

[0112] According to one embodiment of the present invention, the two arms and the external pressure block 1-4-2 are connected to the end face of the beam to form an external pressure-shaped trapezoidal inner wall 1-4-2-4.

The Z-axis slider 1-6-2-1 drives the Y-axis slider 1-6-2-2 to move up and down, so that the welding head 1-6-2-4 can weld the entire beam. For example, the 1-2 external pressure column is provided with a screw guide rail along its height direction, and the welding component 1-6 is provided on the screw guide rail to control the lifting and lowering of the welding component 1-6.

[0115] For example, the welding head 1-6-2-4 can be connected to the Y-axis slider 1-6-2-2 through the welding connection block 1-6-2-3. That is, the welding connection block 1-6-2-3 is fixedly set on the Y-axis slider 1-6-2-2, and the welding head 1-6-2-4 is set on the welding connection block 1-6-2-3. For example, the Y-axis slider 1-6-2-2 can be a linear guide rail, and the welding connection block 1-6-2-3 or the welding head is fixedly connected to the movable slider of the Y-axis slider 1-6-2-2. By controlling the movement of the slider, the welding connection block 1-6-2-3 and the welding head are driven toward or away from the short tube.

By making the two second ends of the X-type connecting rod 1-6-1-4 approach or move away from each other, the two first ends of the X-type connecting rod 1-6-1-4 drive the two beam clamping blocks 1-6-1-6 to approach or move away from each other, so as to clamp or release the beam from the opposite sides of the beam.

[0117] In this embodiment, the welding clamping mechanism 1-6-1 cooperates with the positioning component to clamp the truss to the outer side of the short tube and ensure that the part of the truss to be welded fits the short tube, so as to weld the part of the truss to be welded.
