Description

Technical Field

[0001] The utility model relates to an assistant, in particular to a welding operation assistant, and belongs to the technical field of welding tools. Background Art

[0002] In the daily welding process, electric welding, argon arc welding and other welding will produce extremely dazzling light, which will cause great harm to the eyes of the operators. Therefore, during welding operations, operators must use welding protective masks to work to resist occupational eye damage caused by welding light radiation. However, spot welding exists in many operations, that is, it is necessary to preliminarily fix the parts to be welded, and then weld at one or each connection point to preliminarily fix the parts before proceeding to the next step of welding. In this process, the hands that should have been holding the protective mask are often used to perform the fixing operation, which results in inadequate facial and eye protection, which can easily cause harm to the operators.

[0003] The existing welding auxiliary safety methods mostly use handheld protective masks or head-mounted protective masks, but the following problems are found in actual use: when using handheld protective masks for welding, when welding parts that need to be fixed for spot welding, the personnel need to hold the materials and parts to be welded, which causes the protective masks to be unable to be used normally for a short period of time, causing harm to the human body. When using head-mounted protective masks, because the protective goggles emit light very strongly, if they are put on in advance, it will be impossible to see the required welding position or cause inaccurate welding alignment, wasting manpower and material resources, and also bringing certain safety risks.

[0004] Therefore, it is urgent to improve welding auxiliary tools to solve the above-mentioned problems. Utility Model Content

[0005] The purpose of the utility model is to provide a welding operation assistant, which transforms the existing welding torch and adds an operation assistant. An expandable and retractable high-temperature resistant protective cover is added to the front end of the welding torch. When the welding part needs to be handheld and fixed in spot welding, the protective cover at the front end of the welding torch is opened to cover the strong light, high heat and other radiations of the welding part. Once the spot welding is completed, it can be recovered to the welding torch without affecting the subsequent continuous positioning welding. In this way, the health of the welders themselves can be guaranteed and the welding effect can be not affected.

[0006] In order to achieve the above-mentioned purpose, the main technical solutions adopted by the utility model include:
