Embodiment

[0035] When it is necessary to splice the aluminum outer skin straight plate on the outer wall of the military shelter cabin, first carry out the skeleton assembly and correction: assemble the skeleton of the shelter that needs to cover the outer skin in place, adjust the position, size and shape of the skeleton; clean up before welding : Use a cleaning solution to clean the surface of the skeleton and the straight outer skin, remove dust and oil, wipe the welds with acetone and gasoline, and clean the oxide film on the surface with a polishing machine; docking positioning: place two straight outer skins that need to be spliced ​​together on the On the frame, ensure that there is a 3mm wide weld seam between the two outer skin straight plates; drill rivet holes: Drill a number of rivet holes evenly arranged in an array on the outer skin straight plate and the frame, and two adjacent rivets in the same row of rivets The spacing between them is 100mm; the spacing between the uppe...

Abstract

The invention discloses a splicing process for the aluminum outer skin of a military shelter. The process comprises the steps of assembling sizing of a skeleton, cleaning before welding, butting positioning, drilling of rivet holes, riveting, detection of planeness, welding of the outer skin, rivet welding, weld grinding and the like. According to the splicing process, a weld crosswise and sequence welding mode is adopted, so that outer skin straight plates can be continuously and seamlessly spliced, the smoothness and strength of a spliced weld can be ensured, and the condition of deformation and cracking is avoided; the outer skin straight plates are riveted through rivets, so that the connection stability of the outer skin straight plates relative to the skeleton can be effectively improved, the waterproof sealing performance of a shelter body of the shelter can be effectively improved, and a paint coating at a seam can be completely prevented from being detached; in addition, the rivets are fastened on the outer skin straight plates and the skeleton by virtue of a three-section welding process, so that the rivets can be effectively prevented from being loosened or separated.

Description

technical field [0001] The invention relates to the technical field of aluminum plate splicing technology, in particular to a splicing technology for the aluminum outer skin of a military shelter. Background technique [0002] In the automotive industry, the outer wall of the compartment generally needs to be covered with a layer of metal skin, especially the military shelter cabin, which needs to be covered with a layer of aluminum skin on the outer wall of the cabin. Since the aluminum skin is a straight structure, so in There are a large number of splicing of straight boards and straight boards during splicing. The characteristics of this type of parts are: the spliced ​​sheets are all large sheets, the seams are longer, the outer covering is thinner, and it has higher hardness and strength requirements. [0003] In the prior art, there are generally three types of splicing of the skin of the military shelter cabin body. The first is butt welding. Two skin straight plate...
