Technical Field
[0001] This utility model relates to the field of welding test platform technology, and in particular to a welding test device. Background Technology
[0002] Welding is a process that melts and joins the surfaces of metals or other materials together by heating, pressurizing, or a combination of both. During welding, welding rods, welding wires, or other welding materials are typically used to assist in joining the workpieces. Manual welding is a method where operators use hand tools and rely on their skill and experience to precisely control the heat source and welding materials to join metal parts. This method is generally suitable for locations with limited space and inconvenient equipment, or for special welding tasks requiring high precision and flexibility. Manual welding is widely used in repair, customization, and small-scale production due to its flexibility and adaptability.
[0003] For example, Chinese utility model patent (CN218284342U) discloses a multifunctional rotary welding test platform, which describes: "When it is necessary to adjust the left and right tilt angle of the welding test platform body, loosening the first threaded sleeve allows the welding test platform body to rotate, driving the support rod, bearing, and first rotating shaft to rotate along the first U-shaped plate, adjusting the left and right tilt angle. After adjustment, tightening the first threaded sleeve is sufficient. The operation is simple and the angle of the test platform can be easily adjusted." It also describes the technical problem: "When welding the bottom of a columnar workpiece, it is often necessary to manually adjust the position of the welding head to weld around the circumference of the columnar workpiece. This operation results in a poor visual effect of the weld, and the difficulty in adjusting the angle increases the welding difficulty when welding different sides of the workpiece."
[0004] In summary, existing technologies utilize the welding test platform itself to support the workpiece to be welded. However, this method presents the following technical problems: In actual manual welding, operators need to wear goggles and protective gloves to reduce the harm to their bodies from the high temperatures, sparks, and ultraviolet rays generated during welding. In frequent operations, protective equipment may be lost, resulting in economic losses. Therefore, this application proposes a welding test device to provide a new technical solution to address the technical problems mentioned in the aforementioned patent. Utility Model Content

[0013] As a preferred embodiment of the welding experiment device provided by this utility model, the filtering mechanism includes a support frame, a protective net, a filtering component, and a blocking component.

[0016] Compared with the prior art, the present invention has the following beneficial effects:
[0017] The welding experimental apparatus provided by this utility model reduces the harm to the operator, surrounding environment, and people caused by the high temperature and sparks generated during welding by covering the outer shell of the apparatus with a protective plate, thus improving the protection effect. Furthermore, the operator can directly observe the welding process through the protective plate, and the protective plate can reduce the harm to the operator's eyes caused by the strong light and ultraviolet rays generated during the welding process, thus improving the practicality of the apparatus.

[0018] The welding experimental apparatus provided by this utility model uses a fan to draw outside air into the apparatus's outer shell. After welding, outside air is introduced to guide the welding fumes or harmful gases generated inside the apparatus to the support frame. The fumes and harmful gases undergo primary filtration through a protective mesh at the bottom, followed by secondary filtration through a filter plate, and then further filtration through an activated carbon plate. This reduces the risk of injury to the operator from welding fumes and harmful gases, improving welding safety. Furthermore, moving the fixing block removes it from obstructing the corresponding activated carbon plate or filter plate, allowing for easy removal and replacement. After replacement, releasing the fixing block allows it to engage with the corresponding stop block under the force of a torsion spring, thus blocking the activated carbon plate or filter plate. This simple operation facilitates subsequent replacement and cleaning of the activated carbon plate and filter plate, enhancing the apparatus's practicality. Attached Figure Description

[0028] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention 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 invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.
[0029] As described in the background art, in actual manual welding, operators need to wear goggles and protective gloves to reduce the harm to their bodies from the high temperature, sparks and ultraviolet rays generated during welding. However, in actual frequent operations, there may be cases where protective equipment is lost, resulting in certain economic losses.
[0030] To solve this technical problem, this utility model provides a welding experiment device that is applied to manual welding protection.
[0031] For details, please refer to Figures 1-5 The welding experimental apparatus specifically includes:
[0032] The device housing 1 has a protective mechanism 2 on it, a filter mechanism 3 on the top of it, a fixed shell 4 fixedly connected to the inner wall of it, and a baffle net 5 detachably connected to both ends of the fixed shell 4 by bolts. A fan 6 is fixedly installed on the inner wall of the fixed shell 4.
[0033] The protective mechanism 2 includes a rotating door 7, a protective plate 8, protective components, and limiting components. The rotating door 7 is rotatably connected to the outer wall of the device housing 1. The protective plate 8 is fixedly connected to the inner wall of the rotating door 7. Two protective components are provided inside the rotating door 7. Limiting components are provided on the outer wall of the rotating door 7 and on the upper and lower sides of the two protective components respectively. The material of the protective plate 8 is the same as the material of the goggles used for welding.
[0034] The welding experimental apparatus provided by this utility model reduces the harm to the operator, the surrounding environment, and people caused by the high temperature and sparks generated during welding by covering the outer shell 1 of the apparatus with a protective plate 8, thus improving the protection effect. In addition, the operator can directly observe the welding process through the protective plate 8, and the protective plate 8 can reduce the harm to the operator's eyes caused by the strong light and ultraviolet rays generated during the welding process, thus improving the practicality of the apparatus. The operator can put both hands into the two retaining rings 10 respectively to perform manual welding operations, thereby reducing the damage to the operator's hands caused by the high temperature and sparks of welding. The two retaining rings 10 can be stably installed on the rotating door 7 by the limiting component, reducing the possibility of the protective gloves 11 being lost during frequent operations. Furthermore, the removal and installation of the protective gloves 11 by the limiting component facilitates the operator's replacement of damaged protective gloves 11, thus improving the practicality of the apparatus.
[0035] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.
[0036] Example 1:
[0037] Please refer to Figures 2-4 A welding experiment apparatus, comprising:
[0038] The protective component includes a connecting ring 9, which is movably inserted into the inner wall of the rotating door 7. A retaining ring 10 is fixedly connected to one end of the connecting ring 9 near the outer casing 1 of the device, and a protective glove 11 is fixedly connected to the other end of the connecting ring 9 away from the retaining ring 10. The protective component can protect the operator's hands and reduce the damage to the patient's hands caused by high temperature and sparks during the welding process.
[0039] The limiting component includes a limiting block 12. The limiting block 12 is rotatably connected to the outer wall of the rotating door 7. A spring 13 is fixedly connected to the inner wall of the limiting block 12. A sliding plate 14 is fixedly connected to the outer wall of the spring 13. The sliding plate 14 is slidably connected to the inner wall of the limiting block 12. An L-shaped locking rod 15 is fixedly connected to the outer wall of the sliding plate 14. The L-shaped locking rod 15 is slidably connected to the inner wall of the limiting block 12. The rotating door 7 has a slot 16 and a forward / backward groove 17 that are adapted to the L-shaped locking rod 15. The slot 16 and the forward / backward groove 17 are connected. The limiting component can limit and release the protection component, which facilitates the operator to install and remove the protection component and replace it.
[0040] With the above structural design, when welding is required, the operator places the welding machine and related components along with the workpiece to be welded into the device housing 1. Then, the protective plate 8 is placed over the device housing 1. The operator's gaze then passes through the protective plate 8 to see the welding-related structures, and their hand, through the protective glove 11 and connecting ring 9, is inserted into the retaining ring 10. Welding can then be performed through the two retaining rings 10. When a damaged retaining ring 10 needs to be replaced, the two corresponding sliding plates 14 are pressed towards the center, causing the two corresponding L-shaped locking rods 15 to move closer together, allowing the L-shaped locking rods 15 to enter the infeed / outfeed groove 17. During this process, the spring 13 deforms, and the rotatable limiting block 12 allows the L-shaped locking rods 15 to slide within the infeed / outfeed groove 17 and eventually leave it. The two sliding plates 14 can then be released, allowing the sliding plates 14 to move under the elastic force of the corresponding spring 13. By resetting the L-shaped locking rod 15 and rotating the four limiting blocks 12 one by one, the restriction on the two protective gloves 11 can be released. Then, the two protective gloves 11 can be pulled, so that the two protective gloves 11 drive the two retaining rings 10 through the rotating door 7 via the corresponding connecting rings 9, and then separate from the rotating door 7. Then, the new protective gloves 11 can be passed through the rotating door 7, and the corresponding retaining rings 10 on them are pressed tightly against the outer wall of the rotating door 7. Then, the two sliding plates 14 are pressed towards the center, so that the two L-shaped locking rods 15 are aligned with the positions of the corresponding inlet and outlet slots 17. Then, the limiting blocks 12 are attached to the outside of the rotating door 7, so that the L-shaped locking rods 15 are inserted into the inlet and outlet slots 17. Then, the two sliding plates 14 are released, so that the two L-shaped locking rods 15 are inserted into the locking slots 16 under the elastic force of the corresponding springs 13. The limiting blocks 12 are closed and restricted to the outside of the rotating door 7 one by one, and the installation of the two protective gloves 11 is completed.
[0041] Example 2:
[0042] The welding experimental apparatus provided in Example 1 has been further optimized, specifically, as follows: Figures 5-6 As shown, the filter mechanism 3 includes a support frame 18, a protective net 19, a filter assembly, and a blocking assembly. The support frame 18 is fixedly connected to the inner wall of the device housing 1. The upper and lower ends of the support frame 18 are respectively detachably connected to the protective net 19 by bolts. Two blocking assemblies are provided on the support frame 18. The lower protective net 19 can reduce the blockage of the filter plate 21 by larger particles in the welding fumes. The upper protective net 19 can reduce the damage to the activated carbon plate 20 caused by objects falling from above the device and hitting the support frame 18.
[0043] The filter assembly includes an activated carbon plate 20, which is slidably connected to the inner wall of the support frame 18. A filter plate 21 is slidably connected to the inner wall of the support frame 18 and below the activated carbon plate 20. The activated carbon plate 20 can filter harmful substances in the air, and the filter plate 21 is equipped with a HEPA filter, which can block and filter smaller impurity particles.
[0044] The blocking assembly includes a rotating shaft 22, which is rotatably connected to the outer wall of the support frame 18. A support cylinder 23 is fixedly connected to the outer wall of the support frame 18. The rotating shaft 22 is rotatably connected to the inner wall of the support cylinder 23. A fixing block 24 is fixedly connected to the outer wall of the rotating shaft 22. A torsion spring 25 is sleeved on the outside of the rotating shaft 22. The two ends of the torsion spring 25 are fixedly connected to the outer wall of the fixing block 24 and the inner wall of the support cylinder 23, respectively. A stop block 26 that matches the fixing block 24 is fixedly connected to the outer wall of the support frame 18. The blocking assembly can block or release the activated carbon plate 20 or filter plate 21, which facilitates the subsequent replacement of the activated carbon plate 20 or filter plate 21 by the operator.
[0045] Through the above structural design, when welding is performed inside the outer casing 1, the fan 6 can be controlled to slowly draw outside air into the outer casing 1, carrying smoke and harmful gases from inside the casing 1 towards the support frame 18. The smoke and harmful gases are filtered once by the bottom protective net 19, then filtered a second time by the filter plate 21, and finally filtered by the activated carbon plate 20. When the activated carbon plate 20 or the filter plate 21 needs to be replaced, the fixing block 24 can be moved so that it no longer obstructs the corresponding activated carbon plate 20 or filter plate 21. The rotation of the fixing block 24 drives the corresponding rotating shaft 22 to rotate, causing the corresponding torsion spring 25 to deform. After the obstruction of the activated carbon plate 20 or the filter plate 21 is released, the activated carbon plate 20 or the filter plate 21 can be disassembled and replaced. After replacement, the fixing block 24 can be released, and under the action of the torsion spring 25, the fixing block 24 can be locked into the corresponding stop block 26, thus blocking and restricting the activated carbon plate 20 or the filter plate 21.
[0046] In this application, the fan 6 is electrically connected to the controller and the power supply. The control method of this utility model is controlled by the controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art. The power supply ground is also common knowledge in the art. Since this utility model is mainly used to protect mechanical devices, the control method and circuit connection will not be explained in detail.
