Description

Technical Field

[0001] This utility model relates to the field of aluminum alloy welding, and in particular to a handheld laser welding device for thin aluminum alloy plates. Background Technology

[0002] Aluminum alloys are a widely used material in many fields, favored for their excellent physical and chemical properties. When aluminum alloys need to be fixed, welding equipment is required, and handheld laser welding equipment has received increasing attention in recent years due to its high efficiency, precision, and superior welding quality.

[0003] A search revealed Chinese Patent Publication No. CN221454659U, which discloses a portable handheld laser welding device. The key technical point is that by setting up a welding fume purification component, during laser welding, rotating the connecting plate causes the connecting plate, exhaust fan, and fume hood to rotate around a damping axis until the fume hood is directly above the laser welding head. Then, the exhaust fan, in conjunction with the fume hood, draws the welding fumes upwards, where they are filtered and purified by the filter element and filter screen inside the air filter. This process treats the welding fumes, preventing them from being directly emitted into the air and causing harm to the environment and human health. It addresses the issue that when using a handheld laser welding device, a certain amount of welding fumes is generated. These fumes generally contain harmful particulate matter. Compared to the handheld laser welding machine in the patent, which struggles to treat the fumes generated during welding, direct emission of welding fumes into the air could potentially harm the environment and human health.

[0004] Although the aforementioned device can treat the fumes generated during welding by incorporating a welding fume purification component, the component is horizontally positioned relative to the welding head of the handheld welding torch. This means that the purification component can only effectively purify the upward-drifting fumes when welding vertical workpieces and using the welding torch horizontally. If the handheld welding torch needs to be used vertically or at an angle, the fume purification component not only fails to effectively absorb the upward-drifting fumes, but the fume hood also poses a risk of interfering with the welding operation, making it impractical. Therefore, a handheld laser welding device for aluminum alloy thin plates is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a handheld laser welding device for aluminum alloy thin plates. It aims to improve the problem that in the prior art, when the handheld welding gun needs to be used vertically or at an angle, the welding fume purification component not only cannot effectively absorb and treat the upward-drifting fumes, but the fume hood also poses a risk of affecting the welding operation of the welding head.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: a handheld laser welding device for aluminum alloy thin plates, including a welding gun, a mounting block fixedly connected to the top of the welding gun, mounting rods fixedly connected to the left and right sides of the mounting block, a purification mechanism jointly provided between the two mounting rods, an adjustment component provided on the left side of the mounting rod located on the left, the purification mechanism including a housing, a smoke bowl fixedly connected to the bottom of the housing, a fan fixedly connected to the upper part of the inner wall of the housing, connecting shafts fixedly connected to the left and right sides of the housing, the connecting shafts penetrating and rotatably connected to the mounting rods, the adjustment component including a mounting base, the mounting base fixedly connected to the mounting rods, the connecting shaft located on the left side penetrating and rotatably connected to the mounting base, multiple elastic plates fixedly connected to the left side of the mounting base, a limit block fixedly connected to the left end of the elastic plate, and a control sleeve threadedly connected to the outside of the mounting base.

[0007] As a further description of the above technical solution:

[0008] The control sleeve has a control groove inside, and the limiting block is movably connected to the control groove.

[0009] As a further description of the above technical solution:

[0010] Limiting rings are fixedly connected to the right end of the connecting shaft on the right side and the middle part of the connecting shaft on the left side.

[0011] As a further description of the above technical solution:

[0012] A filter element is threadedly connected to the lower part of the outer casing.

[0013] As a further description of the above technical solution:

[0014] The top of the inner wall of the smoking pipe has an annular groove.

[0015] As a further description of the above technical solution:

[0016] A mounting ring is fixedly connected to the bottom of the filter element, and a filter plate is fixedly connected to the inner side of the mounting ring.

[0017] As a further description of the above technical solution:

[0018] A sealing ring is fixedly connected to the top of the mounting ring, and the sealing ring is movably connected to the ring groove.

[0021] 2. In this utility model, by setting up the mutual cooperation between the filter element and the outer shell, the smoke pipe, the ring groove, the limiting ring, the mounting ring and other components, the replacement of the filter element is more convenient and quick. By sealing the sealing ring, the smoke can only be discharged after being filtered by the filter element, which is more practical. Attached Figure Description

Detailed Implementation

[0029] 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.

[0030] Reference Figure 1 - Figure 2 This utility model provides an embodiment of a handheld laser welding device for aluminum alloy thin plates, including a welding gun 1, which is a laser welding gun used for welding aluminum alloy thin plates. A mounting block 2 is fixedly connected to the top of the welding gun 1 for connecting various components. Mounting rods 21 are fixedly connected to the left and right sides of the mounting block 2 for mounting a purification mechanism 3. A purification mechanism 3 is provided between the two mounting rods 21 for absorbing and treating the fumes generated during welding. An adjustment component 4 is provided on the left side of the mounting rod 21 on the left side for adjusting the angle of the purification mechanism 3 to accommodate different angles of the welding gun 1.

[0031] like Figure 3 and Figure 5 As shown, the purification mechanism 3 includes a housing 31 for connecting various components. Connecting shafts 33 are fixedly connected to both the left and right sides of the housing 31, facilitating the connection between the purification mechanism 3 and the mounting rod 21. The connecting shafts 33 and the mounting rod 21 pass through each other and are rotatably connected, allowing for angle adjustment of the purification mechanism 3. Limiting rings 331 are fixedly connected to the right end of the connecting shaft 33 on the right side and the middle of the connecting shaft 33 on the left side, limiting the position of the purification mechanism 3 to a certain extent. A smoke bucket 32 ​​is fixedly connected to the bottom of the housing 31 for absorbing smoke. A fan 34 is fixedly connected to the upper inner wall of the housing 31 for absorbing the smoke generated during welding. The lower part of the outer casing 31 is threaded with a filter element 35, which is used to absorb and treat the smoke. The top of the inner wall of the smoking bowl 32 is provided with an annular groove 321, which is used to install the sealing ring 353. The bottom of the filter element 35 is fixedly connected with an installation ring 351, which is used to press the sealing ring 353 against the annular groove 321. The inner side of the installation ring 351 is fixedly connected with a filter plate 352, which is used to perform preliminary filtration of the smoke. The top of the installation ring 351 is fixedly connected with a sealing ring 353, which may be made of rubber, and is used to seal the gap between the filter element 35 and the smoking bowl 32, so that the smoke can only pass through the filter element 35. The sealing ring 353 is movably connected to the annular groove 321.

[0032] Please see Figure 4The adjustment component 4 includes a mounting base 41, which is used to connect various components. The mounting base 41 is fixedly connected to the mounting rod 21. The connecting shaft 33 on the left side passes through and is rotatably connected to the mounting base 41. Multiple elastic plates 42 are fixedly connected to the left side of the mounting base 41. These plates are inclined and have a certain degree of elasticity. A limit block 43 is fixedly connected to the left end of the elastic plate 42. This limit block is used to limit the left connecting shaft 33, thereby realizing the angle adjustment of the purification mechanism 3. A control sleeve 44 is threadedly connected to the outside of the mounting base 41. This control sleeve 44 is used to control the opening and closing between the multiple limit blocks 43. The control sleeve 44 has a control groove 441 inside. This groove is frustoconical, with its left diameter smaller than its right diameter. This groove is used to control the opening and closing between the multiple limit blocks 43. Rubber pads are fixedly connected inside the multiple limit blocks 43 for anti-slip purposes. The limit blocks 43 are movably connected to the control groove 441.

[0033] Working principle: When it is necessary to adjust the angle of the purification mechanism 3, rotate the control sleeve 44 to move it away from the mounting base 41. At this time, multiple limit blocks 43 will move to the right side of the control groove 441. Multiple limit blocks 43 will open under the action of the elastic sheet 42, thereby loosening the connecting shaft 33 that is fixed by it. Then the angle of the purification mechanism 3 can be adjusted. When the angle of the purification mechanism 3 is adjusted, simply rotate the control sleeve 44 in the opposite direction so that it tightens the multiple limit blocks 43 through the control groove 441 and fixes the connecting shaft 33 on the left side, thereby fixing the angle of the purification mechanism 3.

[0034] When the filter element 35 needs to be replaced, simply rotate the mounting ring 351. The mounting ring 351 will then cause the filter element 35 to disengage from the housing 31. At this time, the sealing ring 353 will disengage from the ring groove 321. Remove the filter element 35, then align the new filter element 35 with the housing 31 and insert it. Rotate the filter element 35 to fix it to the housing 31 and make the sealing ring 353 snap into the ring groove 321, so that the mounting ring 351 presses the sealing ring 353 against it.

[0035] During the welding process, the fan 34 is turned on, and the fan 34 will draw the generated fumes into the filter element 35. The fumes will be filtered by the filter element 35 and finally discharged by the fan 34.

[0036] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model 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 utility model should be included within the protection scope of the present utility model.
