Description

Technical Field

[0001] The utility model relates to the technical field of aircraft engine parts processing, in particular to a processing device for aircraft engine parts. Background Art

[0002] The main function of an aircraft engine is to provide the power required for the movement of the aircraft, including thrust and pull, to overcome the inertia and air resistance of the aircraft. It is the core component of the aircraft power unit, ensuring that the aircraft can take off, cruise and land normally. The aircraft engine is composed of many parts, and these parts need to be processed.

[0003] When a processing device is used to process a part, the part needs to be fixed by a fixing mechanism on the processing device, and the existing fixing mechanism is usually a fixing method, such as fixing the outside of the part. However, in order to reduce weight, improve structural efficiency and meet specific functional requirements, aircraft engines have some cylindrical parts with hollow interiors. After the outside is fixed, it is not convenient to process the outside of the part. However, if only the inside of the part can be fixed, it is not convenient to process the inside of the part, which limits the use of the processing device. Utility Model Content

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in 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.

[0023] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0024] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present utility model, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined. Example

[0025] See also Figure 1-Figure 5 As shown, this embodiment provides a processing device for aircraft engine parts, including a processing table 1, a mounting cavity 11 is opened on one side of the processing table 1, a second fixing mechanism 3 is installed in the mounting cavity 11, and the upper end of the second fixing mechanism 3 extends to the outside through the through hole opened on the upper side of the processing table 1, and the second fixing mechanism 3 is used to fix the inside of the part.

[0026] The second fixing mechanism 3 includes a bottom plate 31 slidably connected to the through hole of the processing table 1, and a first slide groove 32 is provided on the bottom plate 31. A pair of clamping plates 38 slide in the first slide groove 32. When the clamping plates 38 slide in the opposite direction, the inner wall of the hollow cylindrical part is tightened, thereby fixing the part.

[0027] In addition, anti-slip patterns 39 are provided on the outer sides of the pair of clamping plates 38, and the pair of clamping plates 38 are both arc-shaped structures, so that the shape of the clamping plates 38 is adapted to the shape of the parts, thereby improving the stability of the clamping plates 38 in fixing the parts.

[0028] Furthermore, a bidirectional screw rod 33 is rotatably arranged in the first slide groove 32, and the two ends of the bidirectional screw rod 33 are respectively threadedly connected to two clamping plates 38, and the center of the bidirectional screw rod 33 is connected to a gear 1 34. A gear 2 35 is rotatably arranged inside the bottom plate 31, and the gear 1 34 is meshed with the gear 2 35. The gear 2 35 is driven by a motor. When the gear 1 34 is meshed with the gear 2 35, the gear 1 34 rotates with the bidirectional screw rod 33, so that the two clamping plates 38 move automatically, and the parts are fixed from the inside, so that it is convenient to process the outside of the parts.

[0029] At the same time, the lower side of the bottom plate 31 is connected to the piston end of the cylinder 37. The cylinder 37 is installed on the mounting plate 12 arranged inside the mounting cavity 11. The bottom plate 31 is moved up and down by the push of the cylinder 37. When the inside of the part needs to be fixed, the bottom plate 31 is located on the upper side of the processing table 1. When the outside of the part needs to be fixed, the bottom plate 31 is moved downward, and the first fixing mechanism 2 is installed on both sides of the processing table 1 located on the upper side of the second fixing mechanism 3. The first fixing mechanism 2 is used to fix the outside of the part.

[0030] Specifically, the first fixing mechanism 2 includes a micro hydraulic rod 21 located on both sides of the processing table 1, the piston end of the micro hydraulic rod 21 is connected to the outer plate 22, and a symmetrical sliding rod 23 is slidably arranged on the outer plate 22. One end of the sliding rod 23 is connected to a clamping plate 25, and a spring 24 is sleeved on the sliding rod 23 between the clamping plate 25 and the outer plate 22. The micro hydraulic rod 21 moves the outer plate 22 so that the clamping plate 25 fits against the outer side of the part. As the outer plate 22 continues to move, the clamping plate 25 slides with the sliding rod 23 and squeezes the spring 24, thereby improving the fixing effect of the part.

[0031] When the processing device for aircraft engine parts of the utility model is used, the bottom plate 31 is moved downward by the cylinder 37 so that the part is fixed by the clamping plate 25. At this time, the inside of the part can be processed. When the clamping plate 38 fixes the part, the micro hydraulic rod 21 moves with the clamping plate 25 so that the clamping plate 38 fixes the inside of the part, thereby facilitating the processing of the outside of the part. When the clamping plate 38 and the clamping plate 25 fix the part at the same time, the stability of the part can be further improved. Example

[0032] In order to improve the stability of the splint 25 when using it to fix parts, a second slide groove 36 is symmetrically opened on the bottom plate 31, and the slider arranged on the lower side of the outer plate 22 is slidably connected to the second slide groove 36, so that the bottom plate 31 is located on the upper side of the processing table 1. When the parts are placed on the bottom plate 31, the outer plate 22 is moved by the micro hydraulic rod 21, and the outer plate 22 improves stability during movement by sliding in the second slide groove 36.

[0033] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments.
