The positioning tool is suitable for positioning the backrest 100 of the present structure. The backrest 100 of the present structure is positioned by using the positioning tool. The backrest 100 will not move during the process of punching and trimming, thereby improving the positioning effect of the backrest 100 and thus improving the efficiency of punching and trimming.
[0023] As a preferred embodiment, please refer to Figure 1 and Figure 3 The aircraft seat back 100 punching and trimming positioning tool also includes a fixing platform 300, the lower surface of the fixing platform 300 is used to be detachably fixedly connected to the working table of the trimming and punching device, and the lower surface of the positioning boss 210 is fixed to the upper surface of the fixing platform 300, so as to support the positioning mechanism 200 through the fixing platform 300.
[0024] As a preferred embodiment, please refer to Figure 1 and Figure 3 One end of the positioning boss 210 is bent upward so that one end of the positioning boss 210 is matched with one end of the support plate 110 .
[0025] As a preferred embodiment, please refer to Figure 3 Second positioning grooves 212 are relatively opened on both sides of the upper surface of the positioning boss 210, and the two second positioning grooves 212 are close to the bent end of the positioning boss 210. The two second positioning grooves 212 are respectively used for the convex surface of the corresponding second inner concave boss 115 to slide into. The two second positioning grooves 212 can be used to position the width direction and the length direction of the backrest 100 to enhance the positioning effect of the width direction and the length direction of the backrest 100.
[0026] As a preferred embodiment, please refer to Figure 1 and Figure 3The bent end of the upper surface of the positioning boss 210 is provided with a third positioning groove 213 extending along its width direction. The third positioning groove 213 is used for the convex surface of the corresponding third inner concave boss 116 to slide into. The third positioning groove 213 can be used to further position the length direction of the backrest 100 to enhance the positioning effect of the length direction of the backrest 100.
[0027] As a preferred embodiment, please refer to Figure 1 and Figure 3 The positioning mechanism 200 also includes a positioning frame 220. The positioning frame 220 is a U-shaped structure. The positioning frame 220 is surrounded by the outer side of the positioning boss 210 and fixed to the upper surface of the fixed platform 300. The inner side of the positioning frame 220 abuts against the outer side of the edge guard 120. The positioning frame 220 can be used to further position the length direction of the backrest 100 and the length direction of the backrest 100, so as to further enhance the positioning effect of the width direction of the backrest 100 and the length direction of the backrest 100.
[0028] As a preferred embodiment, please refer to Figure 2 and Figure 3The positioning frame 220 includes a first positioning rod 221, two second positioning rods 222 and two third positioning rods 223. The first positioning rod 221 is arranged along the width direction of the other end of the positioning boss 210. The inner side of the first positioning rod 221 abuts against the outer side of the short side 121 of the edge guard 120.

The inner sides of the two third positioning rods 223 are respectively in contact with the outer sides of the corresponding long sides 122 of the edge guard 120. Since the concave-convex degrees of each of the first inner concave bosses 114 are relatively low, each of the first positioning grooves 21 1 is shallow, in order to improve the positioning effect of the positioning tool on the backrest 100 in the length direction, it is necessary to set an additional positioning frame 220, so that the inner side of the first positioning rod 221 abuts against the outer side of the short side 121, and the convex surfaces of the two second inner concave bosses 115 slide into the corresponding second positioning grooves 212, and the third inner concave bosses 116 slide into the third positioning grooves 213, so as to improve the positioning effect of the backrest 100 in the length direction. The back side of the edge guard 120 has a lower convexity than the back side 112, resulting in a shorter abutment height between the inner side of the edge guard 120 and the outer side of the positioning boss 210. In order to improve the positioning effect of the positioning tool on the backrest 100 in the width direction, it is necessary to set an additional positioning frame 220 so that the inner sides of the two second positioning rods 222 and the inner sides of the two third positioning rods 223 can respectively abut against the outer sides of the corresponding long sides 122, thereby improving the positioning effect on the width direction of the backrest 100.
[0029] As a preferred embodiment, please refer to Figure 1 and Figure 3 The ends of the two second positioning rods 222 close to the first positioning rod 221 are fixedly connected to the two ends of the first positioning rod 221 respectively, so that the positioning tool can also be used as a hot pressing die for the backrest 100.
[0030] As a preferred embodiment, please refer to Figure 3 The two second positioning rods 222 are each provided with a plurality of punching slots 2221 , so that the drill bit of the edge trimming and punching device can pass through the punching slots 2221 to punch holes on the two long sides 122 of the edge guard 120 .
[0031] As a preferred embodiment, please refer to Figure 3 A space 224 is reserved between the third positioning rod 223 and the second positioning rod 222 so that the drill bit of the edge trimming and punching device can pass through the space 224 to punch holes on the two long sides 122 of the edge guard 120 .
[0032] In order to better understand the present invention, the following Figure 1 - Figure 3 The working principle of the technical solution of the utility model is described in detail:
[0033] When in use, the backrest 100 to be trimmed and punched is placed on the positioning boss 210, and the back side 112 of the back plate 110 is fitted with the surface of the positioning boss 210. Since the side walls of the positioning boss 210 are respectively in contact with the inner sides of the corresponding edge guards 120, the inner sides of the two second positioning rods 222 and the inner sides of the two third positioning rods 223 are respectively in contact with the outer sides of the corresponding long sides 122, so that the backrest 100 can be positioned in the width direction. Since the convex surfaces of the first inner concave bosses 114 are respectively slid into the corresponding first positioning grooves 211, the convex surfaces of the two second inner concave bosses 115 are respectively slid into the corresponding second positioning grooves 212, and the third inner concave bosses 116 slide Inserted into the third positioning groove 213, the inner side of the first positioning rod 221 abuts against the outer side of the short side 121, so that the length direction of the backrest 100 can be positioned, and the lower surface of the fixed platform 300 is detachably fixedly connected to the workbench of the trimming and punching device. The two long sides 122 of the edge guard 120 can be punched through the trimming and punching device, and the edge of the edge guard 120 can be trimmed to cut off excess skirt. This positioning tool is suitable for positioning the backrest 100 of this structure. When the backrest 100 of this structure is positioned using this positioning tool, the backrest 100 will not move during the process of punching and trimming, thereby improving the positioning effect of the backrest 100 and thus improving the efficiency of punching and trimming.
[0034] The utility model provides an aircraft seat back 100 punching and trimming positioning tool having the following features:
[0035] Beneficial effects:
[0036] (1) Since the concave-convex degree of each of the first inner concave convex platforms 114 is relatively low, resulting in the depth of each of the first positioning grooves 211 being relatively shallow, in order to improve the positioning effect of the positioning tool on the backrest 100 in the length direction, it is necessary to provide an additional positioning frame 220, so that the inner side of the first positioning rod 221 abuts against the outer side of the short side 121, and the convex surfaces of the two second inner concave convex platforms 115 slide into the corresponding second positioning grooves 212, and the third inner concave convex platform 116 slides into the third positioning groove 213, so as to improve the positioning effect of the backrest 100 in the length direction;
[0037] (2) Since the convexity of the back side of the edge guard 120 is relatively low from the back side 112, the abutment height between the inner side of the edge guard 120 and the outer side of the positioning boss 210 is relatively short. In order to improve the positioning effect of the positioning fixture on the backrest 100 in the width direction, it is necessary to provide an additional positioning frame 220 so that the inner sides of the two second positioning rods 222 and the inner sides of the two third positioning rods 223 can abut against the outer sides of the corresponding long sides 122 respectively, thereby improving the positioning effect of the backrest 100 in the width direction.
[0038] (3) The positioning tool is suitable for positioning the backrest 100 of the structure. By using the positioning tool to position the backrest 100 of the structure, the backrest 100 will not move during the process of punching and trimming, thereby improving the positioning effect of the backrest 100 and thus improving the efficiency of punching and trimming.
[0039] The specific implementation methods of the utility model described above do not constitute a limitation on the protection scope of the utility model. Any other corresponding changes and modifications made according to the technical concept of the utility model should be included in the protection scope of the claims of the utility model.
