Description

Technical Field

[0001] This utility model relates to the field of high-strength aluminum alloy sheet metal technology, specifically to an automatic argon arc welding machine for high-strength aluminum alloy sheet metal. Background Technology

[0002] High-strength aluminum alloy sheet metal is widely used in the automotive industry to create lightweight car bodies. When processing high-strength aluminum alloy sheet metal, an automatic argon arc welding machine is used for welding, and argon gas is used to protect the high-strength aluminum alloy sheet metal.

[0003] For example, the utility model patent with authorization announcement number CN215658357U discloses an argon arc welding device that facilitates auxiliary fixation. It includes a base plate, a fixing component movably mounted on the top of the base plate, a second motor fixedly mounted on one side of the fixing component, a welding head fixedly mounted on the top of the fixing component, an adjusting component movably mounted on the top of the welding head, a first motor fixedly mounted on one side of the adjusting component, a lifting component movably mounted on the top of the adjusting component, and a third motor fixedly mounted on the other side of the lifting component. This utility model, by movably mounting a fixing component on the top of the base plate, can utilize a rotating threaded rod. The movement of the threaded rod drives the movement of a fourth slider, which in turn drives the movement of a moving block. Through the interaction with the fixing block, the weldment is fixed. Simultaneously, a limiting plate in a sliding fifth groove is engaged within the fixing groove, further improving the fixing effect.

[0004] Based on existing solutions and actual production and processing applications, current automatic argon arc welding machines for high-strength aluminum alloy sheet metal still have some problems. For example, while the fixed components limit the sheet metal, this is cumbersome to operate and not convenient for limiting sheet metal of different lengths. Furthermore, adjusting the angle of the sheet metal using a second motor is troublesome when controlling the rotation angle. Additionally, welding slag falls directly onto the base plate, requiring manual cleaning and increasing workload. Therefore, we propose an automatic argon arc welding machine for high-strength aluminum alloy sheet metal to solve the aforementioned problems. Utility Model Content

[0005] The purpose of this utility model is to provide an automatic argon arc welding machine for high-strength aluminum alloy sheet metal, so as to solve the problems mentioned in the background art that the existing automatic argon arc welding machines for high-strength aluminum alloy sheet metal are not convenient for quickly limiting aluminum alloy sheet metal of different sizes, and are not convenient for adjusting the angle for all-round welding, and are also inconvenient for collecting welding slag.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an automatic argon arc welding machine for high-strength aluminum alloy sheet metal, comprising a base plate and a fixed plate fixedly connected to its upper left end for bearing, and a welding component is installed on the upper end of the fixed plate;

[0007] Also includes:

[0008] The upper middle end of the fixed plate and the upper end of the connecting plate are rotatably connected to a rotating shaft, and a connecting plate is fixedly connected to the left end of the rotating shaft, and a protrusion is nested inside the lower end of the connecting plate.

[0009] A slag collection assembly is provided on the lower left side of the connecting plate to collect slag.

[0010] The inner end of the rotating shaft is fixedly connected to a connecting frame, and an electric telescopic rod is bolted to the middle position of the upper end of the connecting frame, and a pressure plate is installed at the lower end of the electric telescopic rod.

[0011] Preferably, the slag collection assembly includes a support plate, an iron plate, a magnetic strip, and a storage frame.

A magnetic strip is magnetically connected to the upper end of the iron plate, and the magnetic strips are symmetrically embedded in the bottom end of the storage frame.

[0012] Preferably, the support plate and the iron plate are nested and connected in the connection port opened at the lower end of the fixed plate.

[0013] Preferably, the bottom end of the connecting plate is integrally connected with a connecting strip, and the connecting strip is slidably connected inside the track, wherein the track is located inside the upper right end of the base plate.

[0014] Preferably, the lower end of the connecting plate is threadedly connected to a threaded rod, and the threaded rod is rotatably connected to the upper end of the base plate, while the left end of the threaded rod is equipped with a first motor.

[0015] Preferably, the connecting plate has a sliding structure on the upper side of the base plate via a threaded rod and a connecting strip, and the pressure plate on the left side of the connecting plate forms a telescopic structure with the connecting frame.

[0016] Preferably, the protrusion is embedded in the connecting handle, and the lower end of the connecting handle is fixedly connected to a connecting shaft, which is rotatably connected to the mounting plate. A second motor is installed on the left end of the connecting shaft, and the mounting plate is embedded in the left end of the fixed plate.

[0017] Preferably, the number of rotations of the rotating shaft is one-quarter of the number of rotations of the connecting handle, and the connecting frame has a rotating structure on the upper side of the base plate via the protrusion and the connecting disc.

[0018] Compared with the prior art, the beneficial effects of this utility model are: the automatic argon arc welding machine for high-strength aluminum alloy sheet metal is convenient for quickly limiting aluminum alloy sheet metal of different sizes, and it is also convenient to adjust the angle for all-round welding, while also making it convenient to collect welding slag.

[0019] 1. It is equipped with a connecting plate and a pressure plate. The structural design of the pressure plate and the connecting frame allows the pressure plate to descend when the electric telescopic rod is working, so that the connecting frame and the pressure plate can restrict the aluminum alloy sheet metal.

[0020] The connecting plate, through the structural design of the threaded rod and connecting strip on the upper side of the base plate, allows the connecting plate to slide to the left through the connecting strip when the threaded rod rotates, until the inner ends of the two sets of aluminum alloy sheet metal on the left and right sides abut together, thus facilitating quick positioning of aluminum alloy sheet metal of different sizes.

The connecting frame, through the structural design of the protrusion and the connecting plate on the upper side of the base plate, enables the rotating shaft to rotate when the connecting handle rotates, via the protrusion and the connecting plate.

[0022] When the shaft rotates, it drives the aluminum alloy sheet metal to rotate through the connecting frame and the pressure plate, thus facilitating angle adjustment and all-round welding;

[0023] 3. It is equipped with a connecting plate and a slag collection assembly. The upper end of the iron plate is magnetically connected to a magnetic strip, so that when the connecting plate moves, it drives the bearing plate to move and adjust its position.

[0024] The position of the storage frame is defined by iron plates and magnetic strips, ensuring that the storage frame is always located under the connection between the two sets of aluminum alloy sheet metal, thus facilitating the collection of welding slag. Attached Figure Description

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Please see Figure 1-6 This utility model provides a technical solution: an automatic argon arc welding machine for high-strength aluminum alloy sheet metal, including a base plate 1, a fixing plate 2, a welding component 3, a connecting plate 4, a slag collection component 5, a connecting strip 6, a track 7, a threaded rod 8, a first motor 9, a rotating shaft 10, a connecting frame 11, an electric telescopic rod 12, a pressure plate 13, a connecting disc 14, a protrusion 15, a connecting handle 16, a connecting shaft 17, a second motor 18, and a mounting plate 19.

[0034] Example: Existing methods use fixing components to limit the movement of sheet metal, but this is cumbersome and inconvenient for limiting sheet metal of different lengths. Therefore, this example uses the following technical solution, such as... Figure 1 , Figure 2 , Figure 4 and Figure 6 Since the pressure plate 13 and the connecting frame 11 form a telescopic structure, the connecting strip 6 is slidably connected inside the track 7, and the connecting plate 4 is in a sliding structure on the upper side of the base plate 1 through the threaded rod 8 and the connecting strip 6.

[0035] Therefore, the left and right sets of aluminum alloy sheet metal are placed inside the left and right sets of connecting brackets 11, so that the outer end of the aluminum alloy sheet metal is attached to the inner wall of the connecting bracket 11. When the electric telescopic rod 12 is working, it drives the pressure plate 13 to descend until the lower end of the pressure plate 13 is tightly pressed against the upper end of the aluminum alloy sheet metal.

[0036] When the first motor 9 is working, it drives the threaded rod 8 to rotate at the upper end of the base plate 1, causing the connecting bar 6 to slide to the left inside the track 7, which causes the connecting plate 4 to drive the connecting frame 11 on the right side to move to the left until the left end of the aluminum alloy sheet metal on the right side is attached to the right end of the aluminum alloy sheet metal on the left side, thus facilitating the quick positioning of aluminum alloy sheet metal of different sizes.

[0037] The existing method uses a second motor 18 to adjust the angle of the plate, but controlling the rotation angle is cumbersome. Therefore, this embodiment uses the following technical solution, such as... Figure 1 and Figure 3 Since the lower end of the connecting plate 14 is internally connected to the protrusion 15, the number of rotations of the rotating shaft 10 is one-quarter of the number of rotations of the connecting handle 16. The connecting frame 11 is in a rotating structure on the upper side of the base plate 1 through the protrusion 15 and the connecting plate 14.

[0038] Therefore, when the second motor 18 is working, it drives the connecting shaft 17 to rotate on the mounting plate 19. When the connecting shaft 17 rotates, it drives the connecting handle 16 to rotate, so that the protrusion 15 is nested and connected to the lower end of the connecting plate 14. The connecting plate 14 drives the rotating shaft 10 to rotate, and the rotating shaft 10 and the connecting frame 11 drive the clamped aluminum alloy sheet metal to rotate.

[0039] The aluminum alloy sheet metal can be rotated 90° each time by the protrusion 15 and the connecting plate 14. After the angle of the aluminum alloy sheet metal is adjusted, the welding component 3 can work to perform welding, thus facilitating the adjustment of the angle for all-round welding.

[0040] The existing welding slag falls directly onto the base plate 1, requiring workers to clean it, which increases the workload. Therefore, this embodiment adopts the following technical solution, such as... Figure 1 , Figure 5 and Figure 6 Since the upper end of the iron plate 502 is magnetically connected to the magnetic strip 503, the bearing plate 501 and the iron plate 502 are nested and connected in the connection port opened at the lower end of the fixing plate 2.

[0041] Therefore, the connecting plate 4 moves to the left, causing the bearing plate 501 to move to the left. The bearing plate 501 can be nested in the connection port at the lower end of the fixing plate 2, so that the fixing plate 2 will not affect the movement of the bearing plate 501. The storage box 504 is placed on the lower side of the connection between the left and right aluminum alloy sheet metal.

[0042] The magnetic strips 503, which are symmetrically arranged on the left and right, are magnetically connected to the upper end of the iron plate 502. The position of the storage frame 504 on the support plate 501 is defined by the iron plate 502 and the magnetic strips 503, thereby facilitating the collection of welding slag. All the electrical components mentioned above are existing technologies and will not be described in detail here.

[0043] All standard parts used in this utility model can be purchased from the market, and irregular parts can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art, and the circuit connection adopts conventional connection methods in the prior art, which will not be described in detail here.

[0044] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
