Electric welding machine capable of automatically replacing welding electrodes

Abstract

The invention discloses an electric welding machine capable of automatically replacing welding electrodes. The machine comprises a machine body, a storage cavity is formed in the machine body, a feeding hole is formed between the upper wall face of the right side of the storage cavity and the upper end face of the machine body in a communicating manner, and a clamping cavity extending rightwards is formed in the right wall face of the feeding hole in a communicating manner. A lifting cavity extending rightwards is arranged in the right wall face of the clamping cavity in a communication manner, and a guide sliding groove with an upward opening is formed in the lower wall face of the storage cavity in a communication manner. According to the electric welding machine, the welding electrodesare stored in the electric welding machine, so that the welding electrodes can be clamped in time, the clamping time is effectively shortened, the working efficiency is improved, meanwhile, the clamping position of the upper end of a core wire can be polished, impurities on the surface of the core wire can be effectively removed, passing of current is accelerated, coating combustion can be more sufficient, meanwhile, toxic gas generated during electric welding can be recycled through the machine, and the situation that operators inhale the toxic gas, and physical and psychological health is affected is avoided.

Description

technical field [0001] The invention relates to the field of welding electrodes, in particular to an electric welding machine capable of automatically replacing welding electrodes. Background technique [0002] In our daily life, we often use welding rods for metal gap welding. Welding rods need to be used in conjunction with electric welding machines. Traditional electric welding machines do not have the function of automatically clamping welding rods. At the same time, a large amount of toxic gases will be generated during the welding process. It is easy to cause the operator to inhale, which will affect the physical and mental health of the operator. When welding, it is often encountered in a narrow and dark space, which will affect the operator's sight, and the welding seam cannot be welded well, which will affect Welding effect, a kind of electric welding machine that can automatically replace welding rod described in the present invention, can solve the above-mentioned...
