[0050] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0051] This embodiment provides an automatic locking machine for aviation plugs, such as Figure 1 and Figure 3 As shown, it includes: a plug placement module 1, a rotation mechanism 2, a tail accessory wrench 3 and a displacement mechanism 4;

[0052] The plug placement module 1 is arranged opposite to the rotation mechanism 2. Figure 6 As shown, the plug placement module 1 is provided with a Figure 7 The profiling groove 101 of the plug body 8 shown in the figure can limit the axial displacement and circumferential rotation of the plug body 8, and a gap is left between the plug body 8 placed in the profiling groove 101 and the profiling groove 101, and the plug body 8 can swing radially in the profiling groove 101 through the gap;

[0053] The tail accessory wrench 3 can clamp and fix such as Figure 7 The tail accessory 9 shown, the rotating mechanism 2 can drive the tail accessory wrench 3 to rotate, and the displacement mechanism 4 can drive the rotating mechanism 2 to move closer to or away from the plug placement module 1;

[0054] The present embodiment provides an automatic locking machine for aviation plugs, which limits the axial displacement and circumferential rotation of the plug body 8 by means of the profiling groove 101 on the plug placement module 1, and enables the tail accessory wrench 3 that clamps and fixes the tail accessory 9 to rotate while being pushed toward the plug placement module 1 through the displacement mechanism 4 and the rotation mechanism 2, so as to achieve the tightening of the tail accessory 9 and the plug body 8;

[0055] like Figure 8 As shown, when the axes of the plug body 8 and the tail accessory 9 do not coincide, as the tail accessory 9 rotates and advances, the plug body 8 radially swings in the profiling groove 101 through the gap left between the profiling groove 101 and the plug body 8, and the plug body 8 moves with the tail accessory 9 to achieve deviation correction, so that the internal thread on the tail accessory 9 is aligned with the external thread on the plug body 8, avoiding thread misalignment after tightening;

[0056] The gap between the profiling groove 101 and the plug body 8 is provided by the matching tolerance of the two. On the premise of ensuring that the size of the profiling groove 101 is larger than the plug body 8, the specific tolerance size can be determined by manufacturing a prototype before mass production and conducting multiple tests on the prototype.

[0057] In a specific embodiment, Figure 3 and Figure 4 As shown, the rotating mechanism 2 includes a motor 201, a support 202, a driving gear 203, a driven gear 204 and an open gear 205, and the driving gear 203, the driven gear 204 and the open gear 205 are all rotatably arranged on the support 202;

[0058] The motor 201 is fixed on the support 202, the driving gear 203 is fixed on the output shaft of the motor 201, and the two driven gears 204 are symmetrically arranged on both sides of the driving gear 203. The bottom end of the driven gear 204 is meshed with the driving gear 203, and the top end of the driven gear 204 is meshed with the open gear 205. The open gear 205 is fixedly connected to the tail accessory wrench 3;

[0059] The two driven gears 204 can avoid the problem that a single driven gear 204 cannot mesh with the open gear 1 when encountering the open gear 1, causing the open gear 1 to stop rotating.

[0071] In a specific embodiment, Figure 1 As shown, it also includes a box 6 for accommodating the rotating mechanism 2 and the displacement mechanism 4;

[0072] The plug placement module 1 is fixed on the top of the box body 6. Figure 2 As shown, a first through hole 601 is opened on the top of the box body 6, the open gear 205 is rotatably set on the top of the support 202, the first through hole 601 protrudes from the top of the support 202, and the slide rail 402 is fixed on the inner side of the bottom of the box body 6.
