Description

Technical Field

[0001] The utility model relates to the technical field of aircraft seat processing, in particular to a seat basin placing device. Background Art

[0002] Airline passenger seats installed and used on aircraft generally consist of chair legs, chair tubes, support plate assemblies, armrests, backrests, seat pans, dining tables, seat cushions and other components. The chair legs, chair tubes, and support plate assemblies form the main structural frame of the seat through bolts, nuts and other connectors. The armrests, backrests, seat pans, and dining tables are connected to the main structural frame of the seat through connectors. The seat pan is used to provide support for the passenger's buttocks. Figure 1 and Figure 2 As shown, the chair basin 100 includes a bottom plate 110, a first edge guard 120, a second edge guard 130 and a third edge guard 140. The bottom plate 110 is a round-shaped structure and has a front side 111 and a back side 112. One end of the bottom plate 110 is bent toward the front side 111. The first edge guard 120 is a U-shaped structure, and its opening is toward the bent end of the bottom plate 110. The first edge guard 120 is arranged on the back side 112 and extends along the outer side of the bottom plate 110. The first edge guard 120 includes a first base side 121 and two first auxiliary sides 122. The second edge guard 130 is a U-shaped structure, and its opening is toward the bent end of the bottom plate 110. The second edge guard 130 is arranged on the back side 112 and extends along the inner side of the bottom plate 110. The second edge guard 130 includes a second base edge 131 and two second auxiliary edges 132. The third edge guard 140 is a U-shaped structure and is arranged on the back side 112. The third edge guard 140 includes a third base edge 141 and two third auxiliary edges 142. The third base edge 141 extends along the outer side of the bent end of the bottom plate 110. One end of the two third auxiliary edges 142 is respectively fixedly connected to the two ends of the third base edge 141, and the other end of the two third auxiliary edges 142 is respectively fixedly connected to the ends of the corresponding two second auxiliary edges 132. After the seat basin of the aircraft seat is made by the hot pressing process, it is necessary to use a positioning tool to position the seat basin, and then use a trimming and punching device to punch holes on the auxiliary edge of the edge guard, and trim the edge of the edge guard to cut off the excess skirt.

The fixed platform 200 is detachably fixedly connected to the workbench of the trimming and punching device. The auxiliary edge of the guard edge can be punched by the trimming and punching device, and the edge of the guard edge can be trimmed to cut off excess skirt. This positioning tool is suitable for positioning the chair basin 100 of this structure. When the chair basin 100 of this structure is positioned by this positioning tool, the chair basin 100 will not move, thereby improving the positioning effect of the chair basin 100 and thereby improving the efficiency of punching and trimming.

[0025] As a preferred embodiment, please refer to Figure 3 One end of the upper surface of the fixing platform 200 is bent downward so that the upper surface of the fixing platform 200 can be adapted to the front side 111 of the base plate 110 , thereby improving the supporting effect of the upper surface of the fixing platform 200 on the base plate 110 .

[0026] As a preferred embodiment, please refer to Figure 3 and Figure 4The first positioning member 310 extends along the outer edge of the bent end of the fixed platform 200. The first positioning member 310 is a first positioning rod 311. The inner side of the first positioning rod 311 is used to abut against the outer side of the third base edge 141.
