Abstract

The invention relates to the technical field of friction welding, in particular to a friction stir welding and welding seam cleaning synchronizing system which comprisese a spindle, an anti-splash cover, a chip removal pipeline and a cutterhead and is characterized in that the lower end of the spindle is connected with the upper end of a shaft shoulder; the lower end of the shaft shoulder is connected with a stirring needle; the lower part of the shaft shoulder is in key joint with the upper part of the cutterhead; the lower part of the cutterhead is connected with a blade group through a screw; the anti-splash cover is arranged on the outer side of the lower part of the spindle in a sleeving manner; the lower part of the anti-splash cover is positioned below the blade group; and one sideof the lower part of the anti-splash cover is connected with one end of the chip removal pipeline. Compared with the prior art, the invention provides the friction stir welding and welding seam cleaning synchronizing system to combine friction stir welding, welding seam cleaning, and flying chip collecting into one working procedure, so that the welding efficiency is greatly improved and the workload is reduced.

Description

technical field [0001] The invention relates to the technical field of friction welding, in particular to a friction stir welding and welding seam cleaning synchronization system. Background technique [0002] Friction stir welding technology is a new type of welding technology, which was mainly used in the aerospace field in the early stage, especially for the welding of aluminum alloys and copper alloys. However, with the rapid development of new energy vehicles, friction stir welding technology has been widely used in the production process of aluminum alloy battery trays. [0003] In the existing friction stir welding welding process, it is necessary to remove the flash and burrs of the weld seam, and it is quite difficult to collect the removed spatter and waste at the same time. It seriously affects the efficiency of friction stir welding and increases the workload. Contents of the invention [0004] In order to overcome the deficiencies of the prior art, the prese...
