Embodiment Construction

[0029] Below in conjunction with accompanying drawing and specific embodiment the present invention is described in further detail:

[0030] This device is to ensure the assembly accuracy during the friction welding of the general assembly of a certain type of storage tank, so that the assembly gap and the stagger amount are less than 0.2mm.

[0031] Such as figure 1 Shown is the overall schematic diagram of the friction stir welding process equipment for the general assembly of storage tanks. It can be seen from the figure that a vertical friction stir welding centering and positioning support device for the general assembly of storage tanks includes a positioner base 1, a base 2. Ring seat 3, inner support tensioning structure 11, barrel section outer hoop assembly 7, fork outer hoop assembly 8, support plate 9, adjustment screw 10, mandrel 12, support sleeve 13, compression cover 14 and compression Wheel 15; wherein, the displacement base 1 is located at the bottom of the ...

Abstract

The invention provides a centering butt joint positioning supporting device for a vertical type stirring friction welding storage box assembly annular seam and relates to the field of aerospace product processing technology equipment. The centering butt joint positioning supporting device comprises a positioner seat, a base, an annular seat, an inner support tensioning structure, a barrel section outer hoop assembly, a fork-shaped outer hoop assembly, supporting plates, adjusting threaded rods, a mandrel, a supporting sleeve, a pressing cover and a pressing wheel. The base is fixedly installed on the upper surface of the positioner seat. The adjusting threaded rods are arranged in the circumferential direction of the upper surface of the top end of the base. The annular seat is horizontally and fixedly installed in an outer box body structure. The inner support tensioning structure is fixedly installed on the annular seat. The barrel section outer hoop assembly and the fork-shaped outer hoop assembly are installed on the outer wall of the outer box body structure. The mandrel is circumferentially, vertically and fixedly installed in the center of the positioner seat, and the top of the mandrel penetrates through the pressing cover. The supporting sleeve wraps the outer wall of the mandrel. The pressing wheel is fixedly installed at the top end of the mandrel. Overall box welding is achieved; the welding efficiency is improved; the high assembling precision is ensured; the production manufacturing cost is reduced; and the aerospace product quality is improved.

Description

technical field [0001] The invention relates to the field of aerospace product processing technology equipment, in particular to a centering butt joint positioning support device for the ring seam of the general assembly of a vertical friction stir welding storage tank. Background technique [0002] The launch vehicle storage tank has a large diameter, thin material thickness, and low structural rigidity. The storage tank is mainly welded by the front and rear short shells, the front and rear bottoms, and the middle cylinder section. The structural material of the product is aluminum alloy. [0003] When the product is assembled and welded, the vertical assembly method is adopted, and the storage tank can rotate along its own axis, and the friction stir welding method is used. [0004] During the welding of this large thin-walled box body, because the box body welding area is thinner, the length of the weld seam is longer, and the structural size is large. Poor rigidity of...
