Description

[0001] This application claims priority to the invention patent application No. 202510950189.9 entitled "A Welding Equipment for Manhole Flanges at the Bottom of Stainless Steel Rocket Storage Tanks", the contents of which are incorporated herein by reference in their entirety. Technical Field

[0002] This invention relates to the field of rocket propellant tanks, and more specifically to a welding device for the manhole flange at the bottom of a stainless steel rocket propellant tank. Background Technology

[0003] In the existing manufacturing of bottom flanges for large-diameter stainless steel rocket propellant tanks, the bottom flanges are mainly welded using a combination of sealing welds and resistance spot welding. In this process, the weld only serves a sealing function, while the resistance spot welds bear and resist the forces exerted by the internal pressure deformation of the tank bottom. Resistance spot welding presents the following challenges in this manufacturing process: First, the mating surfaces of the flange face and the end cap are curved, making gaps prone to appear at the spot weld, and requiring high precision on the mating surfaces. If gaps exist, defects such as shrinkage cavities and incomplete penetration can easily occur. Second, the heat-affected zone of the weld is large, significantly weakening the properties of the base material in the fusion line and heat-affected zone during the welding process, and this weakening is irreparable. Third, the size of the resistance spot welds is limited. Fourth, resistance spot welding is not suitable for welding small flanges.

[0004] To achieve high-quality welding of the bottom flange of large-diameter stainless steel rocket propellant tanks, it is particularly important to design a welding device for the bottom manhole flange of stainless steel rocket propellant tanks. Summary of the Invention

[0028] like Figures 1-5 As shown, this invention provides a welding device for the manhole flange at the bottom of a stainless steel rocket propellant tank, comprising: a welding integrated machine 1. The welding integrated machine 1 includes an integrated machine connecting plate 1-1, a vibrating head component 1-2, a horizontal axis component 1-3, and a vertical axis component 1-4. The vibrating head component 1-2 is disposed on one end face of the integrated machine connecting plate 1-1, and the horizontal axis component 1-3 is disposed on the other end face of the integrated machine connecting plate 1-1 opposite to one end face. The vibrating head component 1-2 is used for welding the welding area. The vertical axis component 1-4 is movably disposed relative to the horizontal axis component 1-3 in the transverse direction. The welding integrated machine 1 also includes at least one of a rolling component 1-5, a clamping component 1-7, and a grinding component 1-6, all disposed on the vertical axis component 1-4 and movably disposed relative to the longitudinal direction of the vertical axis component 1-4. The rolling component 1-5 rolls the welding area. The clamping component 1-7 clamps the welding area. The grinding component 1-6 grinds the welding area.

[0029] In this embodiment, at least one of the rolling component 1-5, the clamping component 1-7, and the grinding component 1-6 can move laterally or longitudinally to adapt to the shape of the weld. This welding equipment has an lap-type structure, capable of laser-welding the stainless steel box bottom flange and end cap. By integrating the gaiter component with at least one of the rolling component 1-5, the clamping component 1-7, and the grinding component 1-6, it facilitates connection with other equipment, is compatible with flange welding in different positions, and offers better compatibility. Furthermore, the welding equipment effectively improves welding quality by performing pre- and post-weld treatment on the welding area using at least one of the rolling component 1-5, the clamping component 1-7, and the grinding component 1-6. Additionally, the welding equipment includes a gaiter component 1-2, providing a large-area welding work area.

[0030] When installing the welding machine 1 onto the required equipment, the welding machine connecting plate 1-1 can serve as a connecting plate between the welding machine 1 and the required equipment to securely connect them. For example, the welding machine connecting plate 1-1 can have multiple screw holes for connecting to other equipment or components. Figure 6 As shown, the all-in-one machine connecting plate 1-1 can be provided with a welding clearance port 1-1-1 so that the welding beam can pass through the clearance port 1-1-1 to weld the welding area.

[0031] like Figure 7 As shown, according to one embodiment of the present invention, the galvanometer component 1-2 includes a galvanometer 1-2-1. The galvanometer 1-2-1 has a large working area, can be connected to the fiber optic heads of various laser light sources, and can convert laser light into various output patterns. For example, spot welding joints, spot welding line segments, spot welding patterns, and continuous welding, etc. For example, the size of the spot welding joints of the galvanometer 1-2-1 is not limited, and the positioning accuracy is high.

[0032] like Figure 7 As shown, according to one embodiment of the present invention, in addition to the vibrating head 1-2-1, the vibrating head component 1-2 also includes a lead screw bracket 1-2-3 and a guide rail bracket 1-2-4. The lead screw bracket 1-2-3 and the guide rail bracket 1-2-4 are disposed on the integrated machine connecting plate 1-1. The lead screw bracket 1-2-3 includes a lead screw motor 1-2-3-1 and a lead screw column 1-2-3-2. A trapezoidal guide rail 1-2-1-1 and a lead screw slider 1-2-1-2 are disposed on the side of the vibrating head 1-2-1. The trapezoidal guide rail 1-2-1-1 is slidably disposed relative to the guide rail bracket 1-2-4. The lead screw slider 1-2-1-2 is sleeved on the lead screw column 1-2-3-2 and engages with the lead screw column 1-2-3-2. When the lead screw motor 1-2-3-1 starts, it controls the lead screw column 1-2-3-2 to rotate. Through the lead screw slider 1-2-1-2, it drives the gaiter head 1-2-1 to move relative to the lead screw column 1-2-3-2 and the guide rail bracket 1-2-4, so as to control the focus of the gaiter head 1-2-1 to the welding position.

[0033] The welding device provided in this embodiment controls the rotation of the lead screw column 1-2-3-2 through the lead screw motor 1-2-3-1, and drives the vibrating head 1-2-1 to move relative to the lead screw column 1-2-3-2 and the guide rail bracket 1-2-4 through the lead screw slider 1-2-1-2, which can automatically control the focus of the vibrating head 1-2-1 to the welding position.

[0034] In this embodiment, for example, as Figure 7 and Figure 8 As shown, the scanning head component 1-2 includes three sets of guide rail brackets 1-2-4. Two sets of trapezoidal guide rails 1-2-1-1 are provided on one side of the scanning head 1-2-1, and one set of trapezoidal guide rails 1-2-1-1 and a lead screw slider 1-2-1-2 are provided on the opposite side. The guide rail brackets 1-2-4 are provided with T-shaped grooves that fit the trapezoidal guide rails 1-2-1-1, and the trapezoidal guide rails 1-2-1-1 are slidably mounted relative to the guide rail brackets 1-2-4. Figure 8 and 9 As shown, the lead screw support 1-2-3 includes a lead screw motor 1-2-3-1 and a lead screw column 1-2-3-2. A lead screw slider 1-2-1-2 is fitted onto and meshes with the lead screw column 1-2-3-2. When the lead screw motor 1-2-3-1 is started, it controls the rotation of the lead screw column 1-2-3-2, which in turn drives the gauging head 1-2-1 to move relative to the lead screw column 1-2-3-2 and the guide rail support 1-2-4 via the lead screw slider 1-2-1-2, automatically controlling the gauging head 1-2-1 to the focal point of the welding position.

[0035] For example, such as Figure 1 The welding equipment is positioned as shown. The lead screw bracket 1-2-3 can control the movement of the gaiter 1-2-1, position the gaiter 1-2-1 in the vertical direction, and ensure the defocusing amount of the gaiter 1-2-1 to the welding position.

[0036] like Figure 7 and 10As shown, according to one embodiment of the present invention, in addition to the scanning head 1-2-1, the scanning head component 1-2 also includes an air knife component 1-2-2. The air knife component 1-2-2 includes two air knife connecting plates 1-2-2-1, an air knife motor 1-2-2-2, a rotating shaft 1-2-2-3, and an air knife 1-2-2-4. The two air knife connecting plates 1-2-2-1 are respectively disposed on opposite sides of the scanning head 1-2-1, and both ends of the rotating shaft 1-2-2-3 are rotatably connected to one of the air knife connecting plates 1-2-2-1. The air knife motor 1-2-2-2 is fixed on the connecting plate 1-2-2-1, and the rotating shaft of the air knife motor 1-2-2-2 is connected to the rotating shaft 1-2-2-3. The air knife 1-2-2-4 is fixed on the rotating shaft 1-2-2-3. When the air knife motor 1-2-2-2 starts, it controls the rotation of the rotating shaft 1-2-2-3, enabling the air knife 1-2-2-4 to rotate from 0 to 180°.

[0037] In this embodiment, the air knife 1-2-2-4 can output high-pressure gas to prevent welding spatter from splashing onto the galvanometer head 1-2-1. The air knife 1-2-2-4 can be rotated to adapt to the welding profile, thus better protecting the galvanometer head 1-2-1.

[0038] like Figure 11 and Figure 12 As shown, according to one embodiment of the present invention, the horizontal axis component 1-3 includes a third horizontal axis guide rail component 1-3-3. The third horizontal axis guide rail component 1-3-3 includes a third horizontal axis guide rail 1-3-3-2 and a third horizontal axis slider 1-3-3-3. The third horizontal axis guide rail 1-3-3-2 is fixedly disposed on the lower end face of the integrated machine connecting plate 1-1 in the transverse direction. The vertical axis component 1-4 is connected to the third horizontal axis slider 1-3-3-3. The third horizontal axis slider 1-3-3-3 is slidably disposed relative to the third horizontal axis guide rail 1-3-3-2 to drive the vertical axis component 1-4 to move laterally.

[0039] In this embodiment, the horizontal axis component 1-3 can position the lateral positions of the rolling component 1-5, the pressing component 1-7, and the grinding component 1-6. For example, the third horizontal axis guide rail component 1-3-3 can be a linear guide rail.

[0040] like Figure 12As shown, according to one embodiment of the present invention, in addition to the third horizontal axis guide rail 1-3-3-2 and the third horizontal axis slider 1-3-3-3, the third horizontal axis guide rail component 1-3-3 also includes a third horizontal axis motor 1-3-3-1. The third horizontal axis motor 1-3-3-1 is used to control the position of the third horizontal axis slider 1-3-3-3 relative to the third horizontal axis guide rail 1-3-3-2. The third horizontal axis guide rail component 1-3-3 also includes two sets of locking plates 1-3-3-5. The two sets of locking plates 1-3-3-5 are respectively disposed near both ends of the third horizontal axis guide rail 1-3-3-2, and the third horizontal axis guide rail 1-3-3-2 is fixedly connected to the integrated machine connecting plate 1-1 through the locking plates 1-3-3-5.

[0041] In this embodiment, for example, the third horizontal axis guide rail component 1-3-3 can be a linear guide rail.

[0042] like Figure 11 , Figure 13 , Figure 14 and Figure 32 As shown, according to one embodiment of the present invention, in addition to the third horizontal axis guide rail component 1-3-3, the horizontal axis component 1-3 also includes a horizontal axis connecting plate 1-3-4. The horizontal axis connecting plate 1-3-4 is fixedly disposed with the third horizontal axis slider 1-3-3-3. The vertical axis component 1-4 includes a vertical axis guide rail component 1-4-3 and a transmission adapter plate 1-4-2-4. The vertical axis guide rail component 1-4-3 includes a vertical axis guide rail 1-4-3-1 and a long slide table 1-4-3-2. The vertical axis guide rail 1-4-3-1 is fixedly disposed on the lower end face of the horizontal axis connecting plate 1-3-4 in the longitudinal direction. The transmission adapter plate 1-4-2-4 is fixedly connected to the long slide table 1-4-3-2. The rolling component, the pressing component, and the grinding component are all disposed on the transmission adapter plate 1-4-2-4. The long slide table 1-4-3-2 is slidably set relative to the longitudinal axis guide rail 1-4-3-1 so as to drive the rolling component, pressing component and grinding component to move longitudinally through the transmission adapter plate 1-4-2-4.

[0043] In this embodiment, the horizontal shaft component 1-3 controls the lateral position of the horizontal shaft connecting plate 1-3-4 to achieve lateral positioning of the rolling component, the pressing component, and the grinding component.

[0044] like Figure 11 and Figure 14As shown, according to one embodiment of the present invention, in addition to the third horizontal axis guide rail 1-3-3-2 and the third horizontal axis slider 1-3-3-3, the third horizontal axis guide rail component 1-3-3 also includes a third horizontal axis slider adapter plate 1-3-3-4. The third horizontal axis slider adapter plate 1-3-3-4 is locked onto the third horizontal axis slider 1-3-3-3. The third horizontal axis slider adapter plate 1-3-3-4 and the third horizontal axis slider 1-3-3-3 form an inverted T-shape. The horizontal axis connecting plate 1-3-4 is provided with a groove adapted to the inverted T-shape to be fixedly connected to the third horizontal axis slider 1-3-3-3 via the third horizontal axis slider adapter plate 1-3-3-4.

[0045] like Figure 11 and Figure 15 As shown, according to one embodiment of the present invention, in addition to the third horizontal axis guide rail component 1-3-3, the horizontal axis component 1-3 also includes a first horizontal axis guide rail component 1-3-1 and a second horizontal axis guide rail component 1-3-2. The first horizontal axis guide rail component 1-3-1 includes a first horizontal axis guide rail 1-3-1-1 and two first horizontal axis sliders 1-3-1-2, the first horizontal axis sliders 1-3-1-2 being slidably disposed relative to the first horizontal axis guide rail 1-3-1-1. The second horizontal axis guide rail component includes a second horizontal axis guide rail and two second horizontal axis sliders, the second horizontal axis sliders being slidably disposed relative to the second horizontal axis guide rail. The horizontal axis connecting plate 1-3-4 is fixedly connected to the first horizontal axis sliders 1-3-1-2 and the second horizontal axis sliders.

[0046] In this embodiment, the first horizontal axis guide rail 1-3-1-1 and the second horizontal axis guide rail can be provided with arc-shaped notches to avoid the laser beam from the galvanizing head 1-2-1. For example... Figure 14 As shown, the horizontal axis connecting plate 1-3-4 is a boss plate with 4 pairs (8) of protrusions. One set (two pairs) of boss plates in the longitudinal direction serves as a positioning and locking plate for fixing to the first horizontal axis slider 1-3-1-2, and the other set (two pairs) of boss plates in the longitudinal direction serves as a positioning and locking plate for fixing to the second horizontal axis slider. The longitudinal axis guide rail 1-4-3-1 is fixedly set on the lower end face of the horizontal axis connecting plate 1-3-4 in the longitudinal direction.

[0047] like Figure 12 , Figure 16 and Figure 17As shown, in addition to the longitudinal axis guide rail component 1-4-3 and the transmission adapter plate 1-4-2-4, the longitudinal axis component 1-4 also includes a longitudinal axis frame 1-4-1 and a transmission mechanism 1-4-2. The longitudinal axis frame 1-4-1 includes a longitudinal axis adapter plate 1-4-1-3, a guide rail plate 1-4-1-1, a limiting plate 1-4-1-2, and a support plate 1-4-1-4. The longitudinal axis adapter plate 1-4-1-3 is fixedly mounted on the lower end face of the transverse axis connecting plate 1-3-4. The guide rail plate 1-4-1-1 is fixedly mounted on the lower end face of the longitudinal axis adapter plate 1-4-1-3 along the longitudinal direction. A limiting plate 1-4-1-2 is provided at each end of the guide rail plate 1-4-1-1 in the longitudinal direction, and the support plate 1-4-1-4 is fixedly mounted on the lower end of the two limiting plates 1-4-1-2 along the longitudinal direction. The longitudinal guide rail 1-4-3-1 is fixedly mounted on the lower end face of the longitudinal adapter plate 1-4-1-3 along the longitudinal direction and is positioned opposite to the guide rail plate 1-4-1-1. The transmission mechanism 1-4-2 includes a rack 1-4-2-1 and a gear 1-4-2-2. The rack 1-4-2-1 is fixedly mounted on the side of the guide rail plate 1-4-1-1 opposite to the longitudinal guide rail 1-4-3-1, with the teeth of the rack 1-4-2-1 facing the longitudinal guide rail 1-4-3-1. The gear 1-4-2-2 meshes with the rack 1-4-2-1. The transmission adapter plate 1-4-2-4 is fixedly connected to the gear 1-4-2-2. One side of the transmission adapter plate 1-4-2-4 is fixedly connected to the long slide table 1-4-3-2, and the opposite side is placed on the support plate 1-4-1-4 and is slidably mounted relative to the support plate 1-4-1-4. Gear 1-4-2-2 moves relative to rack 1-4-2-1 to drive transmission adapter plate 1-4-2-4 to move in the longitudinal direction.

[0048] In this embodiment, the transmission mechanism 1-4-2 achieves longitudinal positioning of the rolling component, the pressing component, and the grinding component by controlling the longitudinal position of the transmission adapter plate 1-4-2-4. The limiting plate 1-4-1-2 is used to limit the range of motion of the gear 1-4-2-2. For example, the longitudinal axis adapter plate 1-4-1-3 can have an elongated oval laser clearance hole.

[0049] like Figure 17 As shown, the transmission mechanism 1-4-2 also includes a transmission motor 1-4-2-3. The transmission motor 1-4-2-3 is mounted on the transmission adapter plate 1-4-2-4. The shaft of the transmission motor 1-4-2-3 is connected to the gear 1-4-2-2 to drive the gear 1-4-2-2 to rotate. When the transmission motor 1-4-2-3 starts, it drives the gear 1-4-2-2 to move relative to the rack 1-4-2-1, thereby causing the transmission adapter plate 1-4-2-4 to move longitudinally. The transmission mechanism 1-4-2 cooperates with the longitudinal axis guide rail component 1-4-3, and by controlling the longitudinal movement of the transmission adapter plate 1-4-2-4, longitudinal positioning of the rolling component, pressing component, and grinding component is achieved.

[0050] like Figure 5 and Figure 18 As shown, the welding machine 1 includes a rolling component 1-5. The rolling component 1-5 includes two opposing rolling drive cylinders 1-5-1, which are mounted on the longitudinal axis component 1-4. The telescopic rods of the two rolling drive cylinders 1-5-1 are each connected to a rolling side fork 1-5-3. Each of the two rolling side forks 1-5-3 is equipped with a rotatable rolling wheel 1-5-6. The telescopic rods of the rolling drive cylinders 1-5-1 extend and retract to move the rolling wheels 1-5-6 toward or away from the welding area, rolling or releasing the weld seam in the welding area.

[0051] In this embodiment, the rolling component 1-5 can roll and flatten the weld after welding, strengthening the weld point and weld seam. Two rolling drive cylinders 1-5-1 are activated, extending or retracting via telescopic rods to drive the rolling roller 1-5-6 toward or away from the welding area, rolling or releasing the weld seam in the welding area.

[0052] For example, the compaction drive cylinder 1-5-1 is located on the lower end face of the transmission adapter plate 1-4-2-4. The compaction drive cylinder 1-5-1 may include a positioning flange plate, an electric cylinder, and a telescopic rod. The positioning flange plate is fixed to the lower end face of the transmission adapter plate 1-4-2-4 to install the electric cylinder. A rectangular groove and a through hole are provided at the end of the telescopic rod. A boss plate with a through hole can be provided at one end of the compaction side fork 1-5-3. The boss plate is placed in the rectangular groove of the telescopic rod and is connected to the telescopic rod of the compaction drive cylinder 1-5-1 by passing through the through hole of the compaction side fork 1-5-3 and the through hole of the telescopic rod of the compaction drive cylinder 1-5-1 via the compaction joint shaft 1-5-2. The compaction joint shaft 1-5-2 may be composed of cylindrical screws and nuts to enable quick installation or replacement of the compaction side fork 1-5-3 and the compaction drive cylinder 1-5-1.

[0053] For example, the rolling side fork 1-5-3 can be an obtuse-angle connecting rod structure. The end of the rolling side fork 1-5-3 furthest from the rolling drive cylinder 1-5-1 is a fork structure, used to mate with the rolling bushing 1-5-4, forming a space to accommodate the rolling bearing 1-5-5. The rolling wheel 1-5-6 has an axially mounted shaft for rolling connection with the rolling bearing 1-5-5. Both sides of the rolling side fork 1-5-3 have countersunk screw holes, and the rolling bushing 1-5-4 has corresponding countersunk screw holes for fixed connection between the rolling side fork 1-5-3 and the rolling bushing 1-5-4. The fork structure of the rolling side fork 1-5-3, on the side opposite to the rolling bushing 1-5-4, has bearing countersunk holes for fixed connection with the rolling bearing 1-5-5.

[0054] For example, the rolling bearing 1-5-5 can be a pressure bearing. For example, the rolling wheel 1-5-6 can include a roller, a shaft, and a positioning bushing. The thickness of the roller can be in the range of 10~30mm, and the diameter can be in the range of 40~100mm.

[0055] like Figure 5 and Figure 19 As shown, the welding machine 1 includes clamping components 1-7. (As indicated...) Figure 19 As shown, the clamping component 1-7 includes two opposing clamping drive cylinders 1-7-5 and a clamping assembly 1-7-1. The clamping drive cylinders 1-7-5 are located on the longitudinal axis component 1-4. The telescopic rods of the two clamping drive cylinders 1-7-5 are each connected to a clamping side fork 1-7-3. The clamping assembly 1-7-1 is located between the two clamping side forks 1-7-3. The telescopic rods of the clamping drive cylinders 1-7-5 extend and retract to move the clamping assembly 1-7-1 toward or away from the welding area.

[0056] In this embodiment, the clamping component 1-7 can clamp the welded overlapping area before welding, eliminating the assembly gap at the overlapping weld. For example, the clamping component 1-7 can be provided with a through-hole 1-7-6 so that the welding beam of the scanning head component 1-2 can pass through the clamping component 1-7 to weld the welding area. For example, the clamping mechanism of the clamping component 1-7 is similar to the clamping mechanism of the rolling component 1-5, and may include a clamping drive cylinder 1-7-5 (e.g., an electric cylinder), a clamping joint shaft 1-7-2, a clamping side fork 1-7-3, and a clamping bushing 1-7-4, etc. For example, the clamping drive cylinder 1-7-5 is disposed on the lower end face of the transmission adapter plate 1-4-2-4.

[0057] like Figure 19 and Figure 20 As shown, the end faces of the clamping assembly 1-7-1 that mate with the two clamping side forks 1-7-3 are respectively provided with clamping shafts 1-7-1-1-3. The clamping shafts 1-7-1-1-3 are rotatably connected to the clamping side forks 1-7-3.

[0058] In this embodiment, the clamping shaft 1-7-1-1-3 of the clamping assembly 1-7-1 is rotatably connected to the clamping side fork 1-7-3, allowing the clamping assembly 1-7-1 to swing according to the shape change of the welding area, ensuring that the end face of the clamping assembly 1-7-1 used to clamp the area to be welded is always in contact with the surface to be welded. For example, the clamping shaft 1-7-1-1-3 of the clamping assembly 1-7-1 is rotatably connected to the clamping bushing 1-7-4 provided at the end of the clamping side fork 1-7-3.

[0059] like Figure 30 and 31As shown, the clamping shaft 1-7-1-1-3 has an air inlet hole along its axial direction. The air inlet hole 1-7-1-1-2 is used to connect to the protective gas source. The clamping assembly 1-7-1 is used to clamp the end of the welding area and has an air outlet hole. The air inlet hole 1-7-1-1-2 communicates with the air outlet hole to provide protective gas to the welding area.

[0060] like Figure 20 and 21 As shown, according to one embodiment of the present invention, the clamping assembly 1-7-1 includes an upper air nozzle 1-7-1-1, a lower air nozzle 1-7-1-2, and a copper nozzle 1-7-1-3. The upper air nozzle 1-7-1-1 is disposed above the lower air nozzle 1-7-1-2, and the upper air nozzle 1-7-1-1 and the lower air nozzle 1-7-1-2 are detachably connected. The upper air nozzle 1-7-1-1 and the lower air nozzle 1-7-1-2 are hollow structures to accommodate the copper nozzle 1-7-1-3.

[0061] like Figures 22-24 As shown, a through-hole 1-7-1-1-5 is opened in the middle of the upper part 1-7-1-1 of the air nozzle, a through-hole 1-7-1-2-1 is opened in the middle of the lower part 1-7-1-2 of the air nozzle, and a through-hole 1-7-1-3-2 is opened in the middle of the copper nozzle 1-7-1-3. The through-hole 1-7-1-1-5, the through-hole 1-7-1-2-1 and the through-hole 1-7-1-3-2 are connected to allow the welding beam (e.g., laser beam) to pass through and weld the welding area.

[0062] In this embodiment, for example, such as Figure 24 As shown, the upper part of the copper nozzle 1-7-1-3 is a conical segment 1-7-1-3-3, which can be an inverted frustum shape. The lower part of the copper nozzle 1-7-1-3 is a cylindrical segment 1-7-1-3-4. Correspondingly, the upper part of the air nozzle 1-7-1-1 is provided with a conical (or frustum-shaped) hollow structure to accommodate the conical segment 1-7-1-3-3 of the copper nozzle 1-7-1-3, and the conical segment 1-7-1-3-3 of the copper nozzle 1-7-1-3 is fitted to the inner surface of the hollow structure of the upper part of the air nozzle 1-7-1-1. The lower part 1-7-1-2 of the air nozzle is provided with a cylindrical hollow structure to accommodate the cylindrical part of the copper nozzle 1-7-1-3. The cylindrical section 1-7-1-3-4 of the copper nozzle 1-7-1-3 is fitted to the inner side of the hollow structure of the lower part 1-7-1-2 of the air nozzle.

[0063] like Figure 20 and Figure 21As shown, according to one embodiment of the present invention, in addition to the upper part 1-7-1-1, the lower part 1-7-1-2, and the copper nozzle 1-7-1-3, the clamping assembly 1-7-1 also includes two locking components 1-7-1-5. The two locking components 1-7-1-5 are respectively disposed on opposite sides of the mating area of ​​the upper part 1-7-1-1 and the lower part 1-7-1-2, and are detachably connected to the upper part 1-7-1-1 and the lower part 1-7-1-2.

[0064] In this embodiment, for example, such as Figure 23 and 25 As shown, locking component 1-7-1-5, upper part of air nozzle 1-7-1-1, and lower part of air nozzle 1-7-1-2 are provided with corresponding locking holes 1-7-1-1-4 (for example, each locking component 1-7-1-5 is provided with four locking holes 1-7-1-1-4) so ​​as to fix the upper part of air nozzle 1-7-1-1 and the lower part of air nozzle 1-7-1-2 through locking component 1-7-1-5.

[0065] For example, the copper nozzle 1-7-1-3 can be a quick-change component. During installation, the upper part of the air nozzle 1-7-1-1 can be installed from the top of the copper nozzle 1-7-1-3, so that the upper part of the copper nozzle 1-7-1-3 (e.g., the conical section) is inserted into the hollow structure of the upper part of the air nozzle 1-7-1-1. Then, the lower part of the copper nozzle 1-7-1-3 (e.g., the cylindrical section) is inserted from the top of the lower part of the air nozzle 1-7-1-2, so that the lower part of the copper nozzle 1-7-1-3 (e.g., the cylindrical section) is inserted into the hollow structure of the lower part of the air nozzle 1-7-1-2. When it is necessary to remove and replace the copper nozzle 1-7-1-3, it can be tapped from the bottom to remove the copper nozzle 1-7-1-3 from the lower part of the air nozzle 1-7-1-2. For example, the upper part of the air nozzle 1-7-1-1 can be made of aluminum or copper. The lower part of the air nozzle 1-7-1-2 can be made of copper (purple copper or brass, etc.). The material for the copper nozzle 1-7-1-3 can be red copper.

[0066] like Figure 22 and Figure 23 As shown, according to one embodiment of the present invention, a positioning pin 1-7-1-2-3 (for example, one positioning pin 1-7-1-2-3 is provided on each diagonally) is provided on the end face where the lower part 1-7-1-2 of the air nozzle abuts with the upper part 1-7-1-1 of the air nozzle. A positioning hole 1-7-1-1-1 adapted to the positioning pin 1-7-1-2-3 is provided on the end face where the upper part 1-7-1-1 of the air nozzle abuts with the lower part 1-7-1-2 of the air nozzle. The positioning hole 1-7-1-1-1 and the positioning pin 1-7-1-2-3 cooperate to realize the abutment between the lower part 1-7-1-2 of the air nozzle and the upper part 1-7-1-1 of the air nozzle.

[0067] like Figure 20 and Figure 21As shown, according to one embodiment of the present invention, a rubber pad 1-7-1-4 is provided at the end of the clamping assembly 1-7-1 used to clamp the welding area. The rubber pad 1-7-1-4 is used to cushion the movement of the clamping assembly 1-7-1, preventing damage to the clamping assembly 1-7-1 or the base material being welded. For example, the rubber pad 1-7-1-4 can be made of high-temperature resistant rubber. For example, the rubber pad 1-7-1-4 is provided at the end of the lower part 1-7-1-2 of the air nozzle used to clamp the welding area.

[0068] In this embodiment, as Figures 26-28 As shown, the lower part of the air nozzle 1-7-1-2 is used to press the end of the welding area and a rubber ring mounting groove 1-7-1-2-5 is provided. The rubber ring mounting groove 1-7-1-2-5 is used to install the rubber pad 1-7-1-4.

[0069] like Figure 22 , 23 As shown in Figures 29, 30, and 31, according to one embodiment of the present invention, a clamping shaft 1-7-1-1-3 is disposed on the upper part 1-7-1-1 of the air nozzle. An air inlet 1-7-1-1-2 is provided on the clamping shaft 1-7-1-1-3 along its axial direction. A venting groove 1-7-1-1-7 communicating with the air inlet 1-7-1-1-2 is provided on the upper part 1-7-1-1-1. At least one (e.g., four) upper venting holes 1-7-1-1-6 extending toward the lower part 1-7-1-2 of the air nozzle are distributed along the circumferential direction of the upper venting groove 1-7-1-1-7. The upper venting holes 1-7-1-1-6 communicate with the air inlet 1-7-1-1-2 through the upper venting groove 1-7-1-1-7. The lower part 1-7-1-2 of the air nozzle, which mates with the upper part 1-7-1-1, is provided with a lower vent hole 1-7-1-2-2 extending toward the upper part 1-7-1-1. The lower vent hole 1-7-1-2-2 communicates with the upper vent hole 1-7-1-1-6. The end face of the lower part 1-7-1-2 of the air nozzle, used to press the welding area, is provided with a lower vent groove 1-7-1-2-6, which communicates with the lower vent hole 1-7-1-2-2. The air inlet 1-7-1-1-2 is connected to the air source so that during the welding process, protective gas is supplied to the welding area in sequence through the upper air venting groove 1-7-1-1-7, the upper air vent 1-7-1-1-6, the lower air vent 1-7-1-2-2, and the lower air venting groove 1-7-1-2-6, so as to provide gas protection for the weld in the welding area.

[0070] like Figure 24 and Figure 28As shown, the cylindrical section 1-7-1-3-4 of the copper nozzle 1-7-1-3 is provided with multiple (e.g., 6 to 12) copper nozzle vent holes 1-7-1-3-1 penetrating its inner and outer sides (e.g., downwardly inclined) along its circumferential direction. The copper nozzle vent holes 1-7-1-3-1 are connected to the lower venting groove 1-7-1-2-6. The protective gas flows from the air inlet 1-7-1-1-2 of the clamping assembly 1-7-1 through the venting groove 1-7-1-1-7, the upper vent hole 1-7-1-1-6, the lower vent hole 1-7-1-2-2, and the lower venting groove 1-7-1-2-6. Then, a portion of the gas is diverted through the copper nozzle vent holes 1-7-1-3-1 into the interior of the copper nozzle 1-7-1-3, delivering protective gas to the welding area.

[0071] In this embodiment, as Figure 28 As shown, for example, the lower venting groove 1-7-1-2-6 has a chamfered angle 1-7-1-2-7 on its edge (e.g., the lower edge), and the lower venting groove 1-7-1-2-6 is connected to the copper nozzle vent hole 1-7-1-3-1 through the chamfered angle 1-7-1-2-7.

[0072] like Figure 5 and 33 As shown, according to one embodiment of the present invention, the welding integrated machine 1 includes a grinding component 1-6. The grinding component 1-6 includes two opposing grinding drive cylinders 1-6-1, which are disposed on the lower end face of the transmission adapter plate 1-4-2-4. The telescopic rods of the two grinding drive cylinders 1-6-1 are respectively connected to a grinding side fork 1-6-3. A rotatable grinding wheel 1-6-6 is disposed between the two grinding side forks 1-5-3. The telescopic rods of the grinding drive cylinders 1-6-1 extend and retract to drive the grinding wheel 1-6-6 toward or away from the welding area, grinding or releasing the welding area.

[0073] In this embodiment, the grinding component 1-6 can grind the weld after welding to eliminate surface defects and improve weld strength. For example, the grinding drive cylinder 1-6-1 is located on the lower end face of the transmission adapter plate 1-4-2-4.

[0074] like Figure 33 As shown, for example, the clamping mechanism of the grinding component 1-6 is similar to that of the crushing component 1-5, and may include a grinding drive cylinder 1-6-1 (e.g., an electric cylinder), a grinding joint shaft 1-6-2, a grinding side fork 1-6-3, and a grinding bushing 1-6-4, etc. The grinding component 1-6 also includes a grinding motor 1-6-5. The motor flange of the grinding motor 1-6-5 can be fixedly connected to the grinding side fork 1-6-3 and the grinding bushing 1-6-4 by screws. The grinding wheel 1-6-6 is connected to the rotating shaft of the grinding motor 1-6-5. Furthermore, by replacing different grinding wheels 1-6-6, different cleaning functions can be achieved for the weld seam.

[0075] like Figure 1 , Figure 34 and Figure 35 As shown, according to one embodiment of the present invention, in addition to the integrated welding machine, the welding equipment also includes a frame 3. The frame 3 includes two opposing supports 3-2. The integrated machine connecting plate 1-1 is disposed above the two supports 3-2. Telescopic cylinder support legs 3-1 are disposed below each of the two supports 3-2, and each telescopic cylinder support leg 3-1 includes a telescopic drive cylinder. The supports 3-2 are connected to the telescopic rods of the telescopic drive cylinders. The telescopic rods of the telescopic drive cylinders extend and retract to adjust the height of the integrated welding machine 1 via the supports 3-2.

[0076] In this embodiment, for example, the telescopic drive cylinder of the telescopic cylinder support leg 3-1 can be a pneumatic cylinder.

[0077] like Figure 34 As shown, according to one embodiment of the present invention, in addition to the welding machine, the welding equipment also includes an external pressure mold 2-1 for the end cap and an inner tube 2-2 for the end cap. The inner tube 2-2 is used to support the end cap and the flange. The external pressure mold 2-1 is disposed on the side of the end cap away from the inner tube 2-2 to press the end cap tightly against the inner tube 2-2. The welding machine is placed on the external pressure mold 2-1 to weld the flange to the end cap.
