For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected, or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.
[0023] Embodiment 1:
[0024] As shown in the attached specification Figures 1-3 As shown, a visual alignment device for the thrust pin of an aircraft engine includes an engine body 1 and a visual alignment mechanism. A visual recognition component 2 is provided on the engine body 1. A plurality of main intersection thrust pin holes are provided on the engine body 1. The visual recognition component 2 is inserted and fixed at the main intersection thrust pin holes. A detection plate 3 is provided in the middle of the visual recognition component 2. A detection disc 4 is provided on one side of the detection plate 3 close to the auxiliary mounting pin 6. The alignment mechanism is located on one side of the visual recognition component 2.
[0025] In the present utility model, the alignment mechanism includes an engine compartment thrust pin hole 5, an auxiliary mounting pin 6, a camera mounting bracket 7, and a visual sensor 8. The engine compartment thrust pin hole 5 is rotatably connected to the auxiliary mounting pin 6. The engine compartment thrust pin hole 5 is of an overall U-shaped structure, and the opening direction of the U-shaped structure is perpendicular to the auxiliary mounting pin 6. The camera mounting bracket 7 is fixedly connected to the tail of the auxiliary mounting pin 6. The inside of the auxiliary mounting pin 6 is a hollow structure. One end of the auxiliary mounting pin 6 away from the camera mounting bracket 7 is connected with an alignment head 10 through a plurality of L-shaped brackets 9. The number of brackets 9 is four, and the four brackets 9 are arranged in an annular array at equal angles at one end of the auxiliary mounting pin 6. A reference disc 11 is provided at the inner side of the alignment head 10 at the position of the bracket 9.
[0026] In the present utility model, the alignment head 10 is inserted into one end of the visual recognition component 2, and the diameter of the alignment head 10 is smaller than that of the reference disc 11. The camera mounting bracket 7 is provided with a circular hole on the side close to the auxiliary mounting pin 6, and the size of the circular hole is assembled and matched with the inner diameter of the auxiliary mounting pin 6. The visual sensor 8 communicates with the inside of the alignment head 10 through the circular hole. The circular hole, the reference disc 11, and the axis of the alignment head 10 are located on the same axis, and can be used as a reference detection point to perform a comparison detection on the visual recognition component 2 fixed on the engine body 1, achieving an alignment effect.
[0027] In the present utility model, the visual sensor 8 is fixed inside the camera mounting bracket 7. The camera mounting bracket 7 is of an overall U-shaped structure. The visual sensor 8 is fixed inside the U-shaped structure of the camera mounting bracket 7 through the auxiliary mounting bracket 12. The auxiliary mounting bracket 12 is of an overall U-shaped structure that matches the size inside the camera mounting bracket. The four corners of the visual sensor 8 on the side away from the auxiliary mounting pin 6 are fixedly connected to the camera mounting bracket 7 by bolts 13. The auxiliary mounting bracket 12 can assist in the installation when the size of the visual sensor 8 is different.
[0028] When the present utility model is specifically implemented, the visual recognition component 2 is fixed on the engine main intersection thrust pin hole. By fixing the engine compartment thrust pin hole 5, the position of the alignment device is limited, and the auxiliary mounting pin 6 can only move in the limited direction. The engine is pushed to the installation position of the visual alignment mechanism. The visual sensor 8 fixed on the camera mounting bracket 7 at the tail of the auxiliary mounting pin 6 can display the recognized image on the display screen of the external device, and the distance between the center of the detection disc 4 inside the alignment head 10 and the center of the reference disc 11, as well as the area of the detection disc 4, can be calculated. For example Figure 4 When the engine and the engine compartment are deflected by a certain angle, the detection disc 4 becomes oval. When the engine and the engine compartment are parallel, the detection disc 4 becomes circular, and at this time, the area of the detection disc 4 is the largest. When the area of the detection disc 4 reaches the largest, and the distance between the center of the detection disc 4 and the center of the reference disc 11 is close to zero. At this time, the engine pin hole is aligned with the engine compartment pin hole. After recognition and alignment, the auxiliary mounting pin 6 is inserted into the visual recognition component 2.
[0029] The above describes the present utility model and its implementation manners. This description is not restrictive. What is shown in the specific implementation manners is only one of the implementation manners of the present utility model, and the actual structure is not limited thereto. All in all, if those of ordinary skill in the art are inspired by it and, without departing from the creative concept of the present utility model, design similar structural manners and embodiments without creative efforts, they should all fall within the protection scope of the present utility model.
