Problems solved by technology

[0003] The welding difficulty lies in that the welding area of ​​the box body is relatively thin, the structural size is large, the rigidity of the box body is poor, and its own resistance to deformation is poor, and the assembly is extremely difficult
The above situation greatly increases the difficulty of welding the circular seam of large thin-walled storage tanks, and relevant measures need to be taken to solve it

Embodiment Construction

[0029] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0030] Such as figure 1 and figure 2 As shown, the rotating base 24 is an annular disc, which is installed on the rotating shaft mechanism and can rotate. The central axis disk 1 is positioned and installed on the rotating base 24 through the positioning platen 18, the positioning bolt 19 and the positioning nut 20. The cylinder body of the central axis disk 1 is covered with a central support ring 2, and its upper end is installed as a top ring 3 through the fixing bolts. Center connecting disc 5 is installed on center supporting ring 2 upper ends, and supporting ring 2 can locate and support central connecting disc 5 simultaneously; Some long struts 6 are fixedly installed by screw thread on the outside of connecting disc 5, 36 are installed in this implementation, in order to make The ends of the extended long struts 6 are insta...

Abstract

The invention belongs to aerospace product machining technology equipment and particularly discloses a positioning support device for stir friction welding of a storage box cylinder section circular seam. A central shaft disk is arranged above a rotating base seat, a support ring is arranged in the center of the central shaft disk, a top ring is arranged above the central shaft disk, a connecting disk is arranged above the central support ring, long support rods are arranged outside the connecting disk, a short support rod is connected with the rear end of each long support rod, and internal threaded holes are arranged in two ends of left end and right end of a double-stud structure of an adjusting sleeve and respectively connected with the long support rods and the short support rods; the rotating base seat is a perpendicular long positioning rod and a pressing rod, and a pressing plate is arranged above the pressing rod; and a perpendicular short positioning rod is installed between the short support rods and the rotating base seat. Due to the cyclic structure which is formed by the long support rods and the short support rods is adopted, products on a cylinder section can be positioned and supported, positioning error is effectively reduced, and tolerance requirements of welding can be met, and at the same time, parameters in the welding process are stable, internal stress and deformation are small, and positioning support device is further favorable for preventing weldments from being pierced through by a stirring needle.

Description

technical field [0001] The invention belongs to aerospace product processing technology equipment, and in particular relates to a positioning support device. Background technique [0002] The ring seam structure diameter of the large thin-walled box is large ( 5000mm), the material is thin, the structural rigidity is weak, and the material is aluminum alloy. When welding, the product is required to be placed horizontally and rotated along the axis. [0003] The welding difficulty lies in that the welding area of ​​the box is relatively thin, the structural size is large, the rigidity of the box is poor, the resistance to deformation is poor, and the assembly is extremely difficult. The above situation greatly increases the difficulty of welding the circular seam of large thin-walled storage tanks, and relevant measures need to be taken to solve it. [0004] It is necessary to design a positioning support device for the welding of the circumferential seam of the intermedi...
