Welding device with preweld cleaning function and welding method

Abstract

The invention relates to a welding device with a preweld cleaning function. The welding device comprises a welding gun body, two electrodes arranged on the welding gun body, rotary telescopic mechanisms and cleaning mechanisms, each electrode comprises an electrode end portion, one rotary telescopic mechanism and one cleaning mechanism are arranged on each electrode, and each rotary telescopic mechanism is connected with the corresponding cleaning mechanism and used for driving the same to axially and telescopically move and rotate relatively to the corresponding electrode; when extending out of the corresponding electrode end portion, each cleaning mechanism is driven through the corresponding rotary telescopic mechanism to rotate and clean surfaces of parts. The welding device can clean the surfaces of the parts at welding positions automatically, rapidly and thoroughly before welding, and has the advantages that processing cost is reduced, the surfaces of the parts are ensured to be cleaned thoroughly, and the like; further, welding quality of a complete automobile body is improved, and quality of an automobile is improved.

Description

technical field [0001] The invention relates to the field of processing and manufacturing, in particular to a welding device capable of cleaning the surface of parts before welding. Background technique [0002] With the improvement of people's living standards and the rapid development of the automobile industry, more and more cars are used in people's daily life. In the continuous development of the automobile industry, people have been paying more attention to factors such as the quality and quality of automobiles, which also put forward higher requirements for equipment, devices, tools, etc. used in the automobile manufacturing process. [0003] Usually, in the process of trial production or mass production of automobile body, it is necessary to use welding equipment to weld parts. The welding device generally includes a welding torch body and two electrodes opposite to the welding torch body. When the parts need to be welded, the parts are placed between the two electr...

Problems solved by technology

[0005] However, the use of manual cleaning of the surface of parts often brings the following problems: on the one hand, manual cleaning requires a large amount of human and material resources, resulting in an increase in processing costs; on the other hand, manual cleaning often leads to poor surface cleaning Thoroughly, it is easy to cause problems such as welding spatter and virtual welding during welding, which will have a negative impact on the welding quality of the vehicle body and reduce the quality and quality of the car.
