Description

Technical Field

[0001] This invention relates to the field of ship welding, specifically to a wire feeding mechanism for a vertical gas welding apparatus. Background Technology

[0002] Vertical gas welding is a highly efficient welding process with high heat input that can be automated. It is an automated welding process that uses a special flux-cored welding wire and CO2 gas protection to perform vertical butt welding. It is used to weld joints in vertical or near-vertical positions. Vertical gas welding has become one of the indispensable and efficient welding methods in the large-scale assembly stage of shipyards. Many large shipyards have adopted this welding method for welding vertical joints in the shipbuilding process. Vertical gas welding is a highly efficient welding equipment used for welding outer plate welds. It brings the most convenient operation efficiency. In construction, it is mainly used for the construction of ship outer plates, side plates in large holds, and bulkheads.

[0003] However, in the current ship construction process, since the outer plating is lifted using a gantry as the lifting device, the swaying of the gantry during lifting causes the wire feeder to become unstable, resulting in the welding torch getting stuck with wire. This prevents the automatic welding machine from welding normally, seriously affecting production efficiency and welding quality. Summary of the Invention

[0004] To address the existing problems, the present invention provides a wire feeding mechanism for a vertical gas welding apparatus, which, when used in conjunction with other devices, can effectively solve the problems mentioned in the background art.

[0005] To solve the above problems, the present invention adopts the following technical solution:

[0006] A wire feeding mechanism for a vertical gas welding device includes a protective housing. Movable slots are provided on both sides of the protective housing. A support mechanism is installed inside each movable slot. The support mechanism includes a positioning support rod, a conical sleeve, and a magnetic block. A movable shaft connects the positioning support rod to the protective housing. An adjustment through hole is provided above the conical sleeve inside the positioning support rod. A positioning mechanism is installed inside the adjustment through hole. The positioning mechanism includes a first positioning connecting rod and a second positioning connecting rod. Threaded sleeves are installed at both ends of the first positioning connecting rod, and threaded joints are installed at both ends of the second positioning connecting rod. A movable ear plate is installed on the upper surface of the protective housing. A movable pull rod is installed inside the movable ear plate. A movable pull rod buckle is installed below the movable pull rod on the upper surface of the protective housing. A magnetic inclined plate is installed inside the movable ear plate on the side away from the movable pull rod buckle.

[0007] As a further embodiment of the present invention: the interior of the protective compartment is provided with an internal material slot, the internal material slot is provided with a welding wire spool, a wire guide mechanism is provided on one side of the welding wire spool, and a drive mechanism is connected to one side of the wire guide mechanism.

[0008] As a further embodiment of the present invention: the wire guide mechanism is equipped with a wire feeding roller on the side near the wire spool, and the protective chamber is provided with a wire outlet tube on the side near the wire guide mechanism.

[0009] As a further embodiment of the present invention: a hatch is installed on one side of the protective cabin, a lifting handle is installed on the upper surface of the protective cabin, and omnidirectional casters are installed on the lower surface of the protective cabin.

[0010] As a further embodiment of the present invention: the threaded sleeve is engaged with the threaded connector, and the outer diameter of both the threaded sleeve and the threaded connector is greater than the inner diameter of the second positioning link.

[0011] As a further embodiment of the present invention: both the first positioning link and the second positioning link are movably connected to the positioning support rod, and the positioning support rod is movably connected to the protective housing through the movable shaft.

[0012] As a further embodiment of the present invention: the positioning support rod is engaged with the movable slot, the movable pull rod is movably connected with the movable ear plate, the movable pull rod is attracted to the magnetic inclined plate, and the movable pull rod buckle is engaged with the movable pull rod.

[0013] As a further embodiment of the present invention: the driving mechanism is electrically connected to the wire guide mechanism, and the welding wire spool is movably connected to the protective housing.

[0014] As a further embodiment of the present invention: the omnidirectional rollers are movably connected to the protective cabin, and the cabin door is movably connected to the protective cabin.

[0015] As a further embodiment of the present invention: the movable pull rod is a magnetic metal component, and the conical sleeve and the magnetic block are both fixedly connected to the positioning support rod.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] 1. When it is necessary to move the entire protective housing, the entire moving rod is pulled out from inside the moving rod buckle. The moving rod is rotated inside the movable ear plate, so that the moving rod and the magnetic inclined plate are attracted to each other. This allows the protective housing to be moved easily by using the moving rod.

[0018] 2. Engage the threaded sleeves and threaded joints at the ends of the first and second positioning rods to clamp and position the two opposing positioning support rods. After the support mechanism and positioning mechanism are fixedly installed, the entire protective housing can be placed vertically. The magnetic block at the lower end of the positioning support rod will attract the bottom surface of the basket, so that the entire protective housing will not shake when the basket shakes.

[0019] 3. Rotate the positioning support rod through the movable shaft and the protective housing so that the magnetic block faces the upper surface of the protective housing. Then, engage the threaded joint and the threaded sleeve to fix the adjusting hole in the position facing the upper part of the protective housing. After rotating the positioning support rod through the movable shaft and the protective housing so that the magnetic block faces the upper surface of the protective housing, the protective housing can be installed in the upper position.

[0020] 4. If the outer diameter of the threaded sleeve and threaded connector is larger than the inner diameter of the adjusting hole, the first positioning link can move freely inside the adjusting hole to control its orientation. Therefore, it can be ensured that the threaded sleeve and threaded connector placed on the outer end of the positioning support rod will not fall off. Attached Figure Description

[0030] like Figure 1-6As shown, this embodiment provides a wire feeding mechanism for a vertical gas welding device, including a protective chamber 1. Movable slots 4 are provided on both sides of the protective chamber 1. A support mechanism 5 is provided inside the movable slots 4. The support mechanism 5 includes: a positioning support rod 501, a conical sleeve 503, and a magnetic block 504. The positioning support rod 501 is engaged with the movable slots 4. A movable shaft 505 connects the positioning support rod 501 and the protective chamber 1, allowing the positioning support rod 501 to be movably connected to the protective chamber 1 via the movable shaft 505. An adjustment through hole 502 is provided above the conical sleeve 503 inside the positioning support rod 501. The conical sleeve 503 and the magnetic block 504 are both fixedly connected to the positioning support rod 501. A positioning mechanism 8 is provided inside the adjustment through hole 502. The positioning mechanism 8 includes: a first positioning connecting rod 801 and a second positioning connecting rod 802. The first positioning connecting rod 801... Both the first positioning link 801 and the second positioning link 802 are movably connected to the positioning support rod 501. Threaded sleeves 803 are installed at both ends of the first positioning link 801, and threaded connectors 804 are installed at both ends of the second positioning link 802. The threaded sleeves 803 and threaded connectors 804 are engaged. The outer diameter of the threaded sleeves 803 and threaded connectors 804 is larger than the inner diameter of the second positioning link 802. A movable ear plate 7 is installed on the upper surface of the protective housing 1. A movable pull rod 3 is provided inside the movable ear plate 7. The movable pull rod 3 is a magnetic metal component. The movable pull rod 3 is movably connected to the movable ear plate 7. A movable pull rod buckle 301 is installed below the movable pull rod 3 on the upper surface of the protective housing 1. A magnetic inclined plate 701 is provided inside the movable ear plate 7 on the side away from the movable pull rod buckle 301. The movable pull rod 3 is attracted to the magnetic inclined plate 701.

[0031] like Figure 2-6 As shown, in this embodiment, the protective housing 1 is provided with an internal storage compartment 101, and the movable pull rod buckle 301 is engaged with the movable pull rod 3. The internal storage compartment 101 is provided with a welding wire spool 102. A wire guide mechanism 103 is provided on one side of the welding wire spool 102. A drive mechanism 104 is connected to one side of the wire guide mechanism 103. The drive mechanism 104 is electrically connected to the wire guide mechanism 103. A wire feed roller 107 is installed on the side of the wire guide mechanism 103 near the welding wire spool 102. The welding wire spool 102 is movably connected to the protective housing 1. A wire outlet tube 106 is opened on the side of the protective housing 1 near the wire guide mechanism 103. A housing door 6 is installed on one side of the protective housing 1. The housing door 6 is movably connected to the protective housing 1. A lifting handle 2 is installed on the upper surface of the protective housing 1. A universal roller 105 is installed on the lower surface of the protective housing 1. The universal roller 105 is movably connected to the protective housing 1.

[0032] The working principle of this invention is as follows: During use, the support mechanism 5 is used to place the entire protective housing 1 on the suspended platform to prevent swaying. Multiple positioning support rods 501 are rotated via a movable shaft 505 and the protective housing 1, causing the positioning support rods 501 to be housed inside the movable groove 4. The first positioning link 801 and the second positioning link 802 are pulled towards the center of the protective housing 1, and the threaded sleeves 803 and threaded connectors 804 at the ends of the first and second positioning links 801 and 802 are engaged, thereby... The two opposing positioning support rods 501 are clamped and positioned. The outer diameter of the threaded sleeve 803 and the threaded connector 804 is larger than the inner diameter of the adjusting hole 502, thus ensuring that the threaded sleeve 803 and the threaded connector 804, located on the outer end of the positioning support rod 501, will not fall off. After the support mechanism 5 and the positioning mechanism 8 are fixedly installed, the protective housing 1 can be placed vertically. The magnetic block 504 at the lower end of the positioning support rod 501 will attract the bottom surface of the basket, so that when the basket shakes, the protective housing 1 will not shake with the basket. After the welding wire is pulled out from the outside of the welding wire spool 102, it passes through the wire feed roller 107 and the wire guide mechanism 103. The welding wire is then pushed out through the wire outlet tube 106 and connected to the welding. When the drive mechanism 104 drives the wire feed roller 107 to work, it pushes the welding wire. When the protective housing 1 is used on a flat surface, after the magnetic block 504 and the basket are disconnected, the positioning support rod 501 is rotated through the movable shaft 505 and the protective housing 1 so that the magnetic block 504 faces the upper surface of the protective housing 1. Then, the first positioning link 801 and the second positioning link 802 are used again. Pushing towards the center of the protective housing 1, and then using the engagement of the threaded joint 804 and the threaded sleeve 803 again, the adjusting hole 502 is fixed at the position facing the upper part of the protective housing 1. This allows the protective housing 1 to follow the movement of the welding machine via the universal rollers 105. When it is necessary to move the protective housing 1 as a whole, the moving rod 3 is pulled out from the inside of the moving rod buckle 301. The moving rod 3 is rotated inside the movable ear plate 7, so that the moving rod 3 and the magnetic inclined plate 701 are attracted to each other. This allows the protective housing 1 to be moved easily using the moving rod 3.
