Description

Technical Field

[0001] The utility model relates to the technical field of engines, in particular to an aerospace engine blade detection device. Background Art

[0002] As a highly complex and precise thermal machine, the aircraft engine is the "heart" of the aircraft. It is not only a powerful driving force for the aircraft to soar into the blue sky, but also a key force to drive the entire aviation industry forward. In the process of producing aircraft engines, the quality of the blades is crucial, so they must undergo strict visual inspection. However, during the inspection process, the inspection device currently used often requires the engine blades to be firmly fixed, and then the shooting angle of the visual inspection equipment needs to be continuously adjusted. The entire operation process is quite cumbersome and complicated. This not only increases the workload of the operator, but may also affect the inspection efficiency and accuracy. Therefore, for the visual inspection device of aircraft engine blades, we urgently need to improve it to simplify the operation process, improve the inspection efficiency, and ensure that each engine blade meets the highest quality standards. .

[0003] To this end, we propose an aircraft engine blade detection device. Utility Model Content

As the main conveyor belt runs, the moving gear cooperates with the rack, thereby driving the connecting rod and the placement rack to rotate. This design facilitates the fixing and rotation of the blade during transportation, thereby facilitating detection by the visual inspection instrument. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] See also Figure 2 As shown, the output end of the motor 2 is fixedly connected to a driving pulley 8, the output end of the motor 2 is connected to the main conveyor belt 1, the input end of the secondary conveyor belt 4 is fixedly connected to a driven conveyor belt 81, and the driven conveyor belt 81 is connected to the main conveyor belt 1 through a belt drive.

[0023] Working principle:

[0024] When the utility model is actually applied, the motor 2 is started to drive the main conveyor belt 1 to start running. Through the precise transmission between the active pulley 8 and the driven conveyor belt 81, the secondary conveyor belt 4 can also run synchronously. This design cleverly ensures that the visual inspection instrument 5 on the secondary conveyor belt 4 and the placement rack 73 on the main conveyor belt 1 always maintain synchronous movement, and the relative positions of the two are stationary. As the placement rack 73 moves smoothly, when it passes the position of the fixed magnetic strip 77, since the moving magnet 75 has the same magnetic pole as the fixed magnetic strip 77, the repulsive force generated between them causes the moving magnet 75 to be pushed, thereby driving the moving gear 76 to move. In this process, the baffle 72 in the placement rack 73 is acted upon by the tension spring 79, compressing and fixing the end of the blade.

[0025] As the main conveyor belt 1 continues to run, the fit between the moving gear 76 and the rack 78 becomes tighter, and the interaction between them drives the connecting rod 71 and the placement frame 73 to rotate smoothly. This design not only achieves stable fixation of the blades during transportation, but also allows them to perform necessary rotation movements, thereby greatly facilitating the inspection work of the visual inspection instrument 5. The whole process is smooth and efficient, ensuring the accuracy and convenience of blade inspection.
