Description

Technical Field

[0001] This utility model relates to the field of marking processing technology for aerospace parts, specifically a marking fixture for aerospace parts. Background Technology

[0002] In the field of aerospace manufacturing, aerospace parts are the core components of aircraft, and their structural precision directly determines the assembly quality, operational safety and service life of the aircraft. Because aerospace parts generally have complex geometric shapes and strict dimensional tolerance requirements after processing, and often use special alloy materials with high strength and high hardness, the marking process before parts processing places extremely high demands on the stability, adaptability and marking accuracy of tooling equipment.

[0003] According to CN210010975U, a drawing device for plates of different thicknesses is described. Under the action of the inclined surface on the guide block, the guide block moves upward. When the guide block moves above the plate, the spring pushes the support plate, so that the guide block and the plate are in close contact, and the drawing pen is in close contact with the plate, which makes it easy to draw lines on plates of different thicknesses.

[0004] This marking device for plates of different thicknesses can press the top center of the plate using an electric push rod and a pressing block. However, when pressing the top center of the material and then marking the line, the operator needs to adjust the position of the plate. When the adjusted position of the plate does not correspond to the previous marking position, it affects the marking accuracy and cutting accuracy. Therefore, it needs to be improved.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0019] This utility model provides the following technical solution: Example 1: Please refer to Figure 1-5 This utility model provides a technical solution: a marking fixture for aerospace parts, including a base plate 1, a fixed platform 5 fixedly connected to the top of the base plate 1, an adjustment mechanism 3 provided inside the fixed platform 5, aerospace material 2 provided inside the adjustment mechanism 3, and a marking mechanism 4 provided at the back of the top of the base plate 1. The adjustment mechanism 3 includes a connecting frame 301, which is fixedly connected to the top inner side of the fixed platform 5. A drive motor 33 is fixedly connected to the left side of the connecting frame 301, and a first bidirectional threaded rod 31 is fixedly connected to the right side of the drive motor 33. The first bidirectional threaded rod 31 is rotatably connected to the inner side of the connecting frame 301. A threaded plate 32 is threadedly connected to the outer side of the first bidirectional threaded rod 31. A fixed frame 36 is fixedly connected to the top of the threaded plate 32. A protective frame 34 is fixedly connected to the outer side of the fixed frame 36. A servo motor 35 is fixedly connected to the top of the protective frame 34. A second bidirectional threaded rod 38 is fixedly connected to the bottom of the servo motor 35. An adjustment plate 37 is threadedly connected to the outer side of the second bidirectional threaded rod 38. A clamping plate 39 is fixedly connected to the inner side of the adjustment plate 37.

[0020] Furthermore, the inner sides of the connecting frame 301 and the fixed platform 5 are provided with a sliding groove corresponding to the movement trajectory of the threaded plate 32, and the threaded plate 32 is slidably connected inside the sliding groove. The sliding groove can limit the threaded plate 32, allowing the threaded plate 32 to slide inside the connecting frame 301 and the fixed platform 5. When the threaded plate 32 moves, it can drive the fixed frame 36 to move, thereby adjusting the position of the clamping plate 39.

[0021] Furthermore, the inner sides of the protective frame 34 and the fixing frame 36 are provided with limiting grooves corresponding to the movement trajectory of the adjusting plate 37, and the adjusting plate 37 is slidably connected inside the limiting groove. The limiting groove can limit the adjusting plate 37, making the adjusting plate 37 more stable during the lifting and lowering process.

[0022] Furthermore, the clamping plate 39 is disposed on the outside of the aerospace material 2, and the inner side of the clamping plate 39 is in close contact with the outer side of the aerospace material 2. The clamping plate 39 can clamp and fix the aerospace material 2, making the aerospace material 2 more stable and the line drawing more accurate when drawing lines.

[0023] Example 2: Please refer to Figure 1-5 Furthermore, based on Embodiment 1, the line drawing mechanism 4 further includes a first hydraulic cylinder 41, which is fixedly connected to the right back end of the base plate 1. A support block 42 is fixedly connected to the left side of the first hydraulic cylinder 41. A connecting frame 43 is fixedly connected to the top of the support block 42. A third hydraulic cylinder 46 is fixedly connected to the top of the connecting frame 43. A lifting plate 44 is fixedly connected to the bottom of the third hydraulic cylinder 46. A fixed frame 48 is fixedly connected to the front of the lifting plate 44. A second hydraulic cylinder 45 is fixedly connected to the back end of the lifting plate 44. A moving block 47 is fixedly connected to the front of the second hydraulic cylinder 45. The moving block 47 is slidably connected to the inside of the fixed frame 48. A one-way threaded rod 49 is threadedly connected inside the moving block 47. A V-shaped clamp 402 is rotatably connected to the left side of the one-way threaded rod 49. The V-shaped clamp 402 is slidably connected to the inside of the moving block 47. A line drawing pen 401 is provided inside the moving block 47.

[0024] Furthermore, a moving groove corresponding to the movement trajectory of the support block 42 is provided on the inner back end of the base plate 1, and the support block 42 is slidably connected to the inside of the moving groove. Through the moving groove, the support block 42 can slide on the inner side of the base plate 1, making the support block 42 more stable during movement.

[0025] Furthermore, the drawing pen 401 is disposed inside the V-shaped clamp 402, and the left side of the drawing pen 401 is in contact with the left side of the moving block 47, and the outer side of the drawing pen 401 is in contact with the inner side of the V-shaped clamp 402. Through the cooperation of the V-shaped clamp 402 and the moving block 47, the drawing pen 401 can be clamped and fixed.

[0026] In actual operation, when this device is used, when it is necessary to draw lines on the aviation material 2, and when the position of the clamping plate 39 needs to be adjusted according to the size of the aviation material 2, the drive motor 33 is started. The drive motor 33 drives the first bidirectional threaded rod 31 to rotate inside the connecting frame 301, so that the first bidirectional threaded rod 31 drives the threaded plate 32 to move. When the threaded plate 32 moves, the fixing bracket 36 fixed on the top of the threaded plate 32 moves synchronously with the threaded plate 32, thereby driving the protective frame 34 on the outside of the fixing bracket 36 and the clamping plate 39 on the inside to move laterally until the clamping plate 39 initially approaches the two sides of the aerospace material 2, completing the lateral position calibration. Start the servo motor 35, which drives the second bidirectional threaded rod 38 to rotate inside the protective frame 34. This causes the second bidirectional threaded rod 38 to move the adjusting plate 37, which in turn causes the adjusting plate 37 to lift the clamping plate 39 until the inner side of the clamping plate 39 is completely in contact with the outer side of the aerospace material 2. This creates a clamping force on the aerospace material 2 from the longitudinal direction, ultimately achieving a stable fixation of the aerospace material 2 and providing a stable foundation for subsequent line drawing. Start the first hydraulic cylinder 41. The first hydraulic cylinder 41 pushes the support block 42, the connecting frame 43 and the lifting plate 44 to move laterally, and initially adjusts the relative position of the drawing pen 401 and the aviation material 2 in the lateral direction so that they are aligned with the area to be drawn. The third hydraulic cylinder 46 is activated, which drives the lifting plate 44 to move downward. This causes the fixed frame 48 on the front of the lifting plate 44, the second hydraulic cylinder 45 at the back end, and the moving block 47 to move downward synchronously with the lifting plate 44. This adjusts the height of the drawing pen 401 so that the tip of the drawing pen 401 accurately contacts the surface of the aerospace material 2. The second hydraulic cylinder 45 at the back end of the lifting plate 44 is activated, which pushes the moving block 47 to slide longitudinally along the inner side of the fixed frame 48. This fine-tunes the position of the drawing pen 401 in the longitudinal direction so that it is accurately aligned with the line to be drawn. After the position calibration is completed, the second hydraulic cylinder 45 is controlled to push the moving block 47 to move at a constant speed. The drawing pen 401 with animation slides on the surface of the aerospace material 2 along the set trajectory, and finally completes the precise drawing operation. If the drawing pen 401 needs to be replaced, the V-shaped clamp 402 can be loosened by rotating the one-way threaded rod 49 in the opposite direction, so as to easily replace the drawing pen 401.
