Problems solved by technology

[0006] The technical problem to be solved in the present invention is: with the continuous operation, a large amount of spatter will be generated during welding with carbon dioxide shielded welding, so that the protective tip of the welding torch will be blocked by welding slag, which will affect the transportation of carbon dioxide and the use of welding wire, so pay attention to it at all times when welding. Clean the protective nozzle. When cleaning the protective nozzle of the welding torch, it is usually used to remove the protective nozzle of the welding torch for cleaning. The cleaning process is cumbersome and affects the welding efficiency.

specific Embodiment approach

[0054] As a specific embodiment of the present invention, the wiper assembly 6 includes:

[0055] A fixed seat 61, the inner side of the fixed seat 61 is rotatably connected with the protective mouth 5, and the end of the fixed seat 61 away from the mouth of the protective mouth 5 is connected with the drive assembly 7;

[0056] Blade 62, said blade 62 is fixedly connected with fixed seat 61, and the blade is located in protective mouth 5, and said blade 62 is connected with fixed seat 61 to form a concave shape, and cleans the inside and surface of protective mouth 5.

[0057]After the staff has performed the welding operation for a period of time, it is necessary to clean up the welding slag on the protective nozzle 5. After the worker stops the machine, he drives the fixed seat 61 to rotate by rotating the drive assembly 7. At this time, the fixed seat 61 and the blade 62 are driving Driven by the component 7 to rotate, the concave fit between the fixed seat 61 and the blad...

Abstract

The invention relates to the technical field of welding devices, in particular to a carbon dioxide protection welding machine which comprises a welding machine body and a welding gun, the welding gun is fixedly connected with the welding machine body through a wire feeding mechanism, the carbon dioxide protection welding machine further comprises a protection nozzle, and the protection nozzle is in threaded connection with the welding gun; the scraping and wiping assembly is arranged on the protection nozzle and rotationally connected with the protection nozzle, and the scraping and wiping assembly is used for scraping and cleaning the welding slag in the protection nozzle; the driving assembly is arranged on the protection nozzle in a sleeving manner and is used for driving the scraping assembly to rotate; the driving assembly drives the scraping assembly to rotate, then the scraping assembly scrapes and cleans welding slag in the welding gun, the problem that a protection nozzle is blocked due to splashing in daily welding operation is solved, the situation that welding operation is delayed due to the fact that the protection nozzle is blocked and detached and cleaned is improved, the time for cleaning the welding slag is shortened, and the welding efficiency is improved. And the efficiency of welding operation is improved.

Description

technical field [0001] The invention relates to the technical field of welding devices, in particular to a carbon dioxide shielded welding machine. Background technique [0002] As a welding technology with simple operation, high welding efficiency and good welding quality, carbon dioxide shielded welding is widely used in various steel structure projects in modern society; [0003] The working principle of carbon dioxide shielded welding: the welding wire and the weldment are used as two electrodes to generate an arc, the heat of the arc is used to melt the metal, and carbon dioxide gas is used as a shielding gas to protect the arc and the molten pool to complete the welding work; [0004] In the prior art, carbon dioxide shielded welding is to feed the wire to the welding torch through the wire feeder, and the welding work is carried out under the protection of carbon dioxide. , A large amount of spatter will be generated during carbon dioxide shielded welding, so that th...
