Flexible assembly welding device for thin-wall parts

Abstract

The invention discloses a flexible assembly welding device for thin-wall parts. The flexible welding device comprises a frame, a three-jaw chuck mechanism, a linkage clamping mechanism and an inner wall pressing mechanism; the frame comprises multiple vertical rods surrounding a cylinder, a cross beam for connecting the multiple vertical rods together and stand columns positioned among the multiple vertical rods; the three-jaw chuck mechanism is arranged on the bottom side in the frame and used for tensioning the thin-wall parts positioned in the frame; the linkage clamping mechanism is connected with the vertical rods and used for clamping the outer sides of the thin-wall parts in the frame; and the inner wall pressing mechanism is connected with the stand columns and used for pressing the thin-wall parts positioned in the frame. The flexible welding device can realize automatic centering of the thin-wall parts such as stirring cylinders and the like to reduce positioning deviations,is suitable for tank bodies with different shapes and sizes to realize flexible welding of the thin-wall parts, effectively controls alignment tolerances of the tank bodies to smoothly realize automatic welding of later stirring cylinders, and is portal in structure and convenient to maintain.

Description

technical field [0001] The invention belongs to the technical field of machinery, in particular, the invention relates to a welding device for thin-walled parts. Background technique [0002] Thin-walled parts need to be clamped to maintain stability during processing. For example, during the production process of mixing drums, spherical tanks need to be clamped and then welded. Because the thickness of thin-walled parts is relatively thin, it is easy to deform due to external pressure during the clamping process, thereby affecting the processing accuracy. The clamping device in the prior art has a bulky overall structure, the workpiece cannot be self-centered, and the outer wall of the thin-walled part is easily damaged. [0003] In the welding and manufacturing process of the mixing drum, bird cage or squirrel cage tooling is basically used in the industry at present, and the cylinder body of each section of the mixing drum is forced to be squeezed together by fixed tooli...
