Embodiment Construction

[0020] This embodiment is a welding assembly tool for the upper cover plate, the lower cover plate, the support bars on both sides and the rear panel of a certain airborne communication chassis frame. The length of the upper cover plate is l=310mm, the width w=152.5mm, and the height h=14mm. The length of the lower cover plate is l=310mm, the width w=152.5mm, and the height h=10mm. The external dimensions of the support bars on both sides are the same, the length is l=212mm, the width w=10mm, and the height h=10mm. The length of the rear panel is l=320mm, width w=217mm, and height h=41.8mm. After assembly, the amount of misalignment is guaranteed to be within 0.2mm and uniform, and the gap is guaranteed to be within 0.1mm and uniform. The part material is 5A06 aluminum alloy.

[0021] This embodiment includes two clamping plates 7 used in pairs, four pressing plates 8 and pull rods 10. The four pressure plates are divided into two groups, which are respectively fixedly connecte...

Abstract

The invention discloses an assembly welding tool of a high-precision frame structure. The assembly welding tool comprises two clamping plates used pairwise, four pressing plates and a pull rod. The four pressing plates are divided into two sets; and the two sets of pressing plates are fixedly connected with wedged blocks on the two clamping plates through an inserting mode, and are positioned on the two sides of the two clamping plates. The middle part of the pull rod and one end of the pull rod are mounted in through holes in the geometric centers of the two clamping plates, and are fastenedthrough nuts; and the pull rod and the through holes of the clamping plates are in interference fit. The other end of the pull rod is positioned out of the clamping plate on the side, and is used forfixedly connecting with a chuck of a vacuum electronic beam welding machine. The assembly welding tool is used for a vacuum electronic beam welding assembly chassis, guarantees the alignment tolerance, controls the welding deformation and the frame rotation, can guarantee the welding line alignment tolerance, constrains a whole frame, and prevents deformation of the frame in the welding process; and meanwhile, the tool enables the frame to rotate, so that all welding lines can be welded under vacuum of the same furnace, and the welding efficiency and quality are improved.

Description

Technical field [0001] The invention relates to the field of assembling frames for airborne communication cases, in particular to an assembling and welding tool for metal frames. Background technique [0002] The frame is composed of the upper cover plate, the lower cover plate, the first support bar, the second support bar and the rear panel by vacuum electron beam welding. The frame is a precision product. After welding, the tolerance of the length, width and height is ±0.2mm. At the same time, the difference between the upper and lower diagonals must not be greater than 0.25mm, and the control of welding deformation requires high. In addition, in accordance with the requirements of GJB1718A-2005 "Electron Beam Welding", and in order to ensure the frame size after welding, the assembly quality must meet the misalignment of not more than 0.2mm and uniform, and the gap is not more than 0.1mm and uniform. [0003] The frame is composed of five parts. The welding seam is a combinati...
