Protective device used for heavy truck cab assembly welding

Abstract

The invention relates to the technical field of heavy truck cab welding, in particular to a protective device used for heavy truck cab assembly welding. The protective device comprises a base, a welding mechanical arm and a plumb joint. The upper end surface of the base is fixedly connected with the welding mechanical arm and a waste gas treatment device which are distributed left and right. The left end surface of the welding mechanical arm is fixedly connected with the plumb joint. The outer side of the plumb joint is in sliding connection with a protective unit. The upper end surface of theprotective unit is fixedly connected with the welding mechanical arm. A limit unit is arranged at the right side of the welding mechanical arm. The lower end surface of the limit unit is fixedly connected with the welding mechanical arm. According to the protective device provided by the invention, by arranging a fixing frame, a spiral ring and a push rod, a protective hood achieves shielding andprotecting purposes, and human eyes are not affected; an arranged telescopic spring has a certain buffer effect when the protective hood makes contact with a machine and protects the protective hoodagainst collision damage; and an arranged collecting box can collect fragments, and the situation that the welding fragments spatter everywhere and affect a working environment is avoided.

Description

technical field [0001] The invention relates to the technical field of heavy truck cab welding, in particular to a protective device for heavy truck cab assembly welding. Background technique [0002] Heavy truck is the abbreviation of heavy truck, which is an authentic, traditional and informal name for heavy trucks and semi-trailer tractors, including all kinds of special vehicles, dump trucks, trucks and some trucks that you see on the road. Rare off-road vehicles, currently in the production process of heavy trucks, the cab assembly of heavy trucks needs to be welded separately. During the welding process, welding debris will inevitably splash everywhere. Once the high-temperature debris comes into contact with the skin of the staff, the consequences will be disastrous. Therefore, the demand for a protective device for welding of a heavy truck cab assembly is increasing day by day. [0003] At present, the heavy-duty truck cab assembly in the market is welded by special...

AI Technical Summary

Problems solved by technology

[0003] At present, the heavy-duty truck cab assembly in the market is welded by special welding equipment. There will be staff on the welding site for other work. The following problems are prone to occur during welding. First, a large amount of toxic gas is generated during welding, and the staff spends a long time Inhalation of these toxic gases is easy to affect the human body. Second, there will be debris splashing during welding. Once the debris comes into contact with people's skin, the consequences will be unimaginable. At the same time, the falling debris will also affect the working environment. Light is generated, and the strong light of welding is a threat to the eyes of the staff. Fourth, there will be a large number of wires distributed around during welding. Once the mechanical arm is in operation, once the wires are clamped, it is easy to affect the quality of the wires. Its normal service life cannot be guaranteed, therefore, a protective device for heavy truck cab assembly welding is proposed in view of the above problems
