Description

Technical Field

[0001] The utility model relates to the technical field of aircraft seat processing, in particular to a positioning device for a shoulder support plate. Background Art

[0002] Aircraft seat shoulder support is one of the important components of aircraft seats, which is used to provide support for passengers' shoulders. Figure 1 and Figure 2 As shown, the shoulder support plate 100 includes a base plate 110 and a side guard 120, the base plate 110 has a front side 111 and a back side 112, the base plate includes a first plate surface 113, two second plate surfaces 114 and a third plate surface 115, the first plate surface 113 is a trapezoidal structure, the two second plate surfaces 114 are triangular structures, the two second plate surfaces 114 are relatively arranged on both sides of the first plate surface 113, one side of the two second plate surfaces 114 is respectively fixed to the corresponding oblique side of the first plate surface 113, and is bent toward the front side 111, the third plate surface 115 is a rectangular structure, and the third plate surface 115 is provided on one side of the first panel 113. One side of the third panel 115 is fixedly connected to the long side of the first panel 113 and bent toward the front surface 111. The edge guard 120 is a U-shaped structure and is provided around the periphery of the base plate 110. The front side of the edge guard 120 is flush with the front surface 111, and the back side of the edge guard 120 protrudes from the back surface 112. The edge guard 120 includes a long guard 121 and two short guards 122. The long guard 121 extends along the short side of the first panel 113, and the two short guards 122 extend along the other two sides of the corresponding second panel 114. After the aircraft seat shoulder support is formed through the hot press forming process, it is positioned using a positioning tool. Then, a trimming and punching device is used to punch holes in the first panel and the edge guard. The edges of the edge guard are trimmed to remove excess skirting. Existing positioning tooling (such as a synchronous assembly tooling for seat backs and seat foams disclosed in application number 201510442168.2) is not suitable for positioning the shoulder support panels of aircraft seats of this structure. When the existing positioning tooling is used to position the shoulder support panels of aircraft seats of this structure, the shoulder support panels of the aircraft seats are prone to movement during the process of punching and trimming, resulting in poor positioning of the shoulder support panels of the aircraft seats and reduced efficiency of punching and trimming.
