Description

Technical Field

[0001] The utility model relates to the technical field of precise shape detection, in particular to a precise shape detection device for investment casting castings with multi-stage overlapping sections for aviation use. Background Art

[0002] In the aviation field, when using investment casting castings with multi-stage overlapping sections, precise shape detection devices play a crucial role. These devices adopt advanced optical measurement or three-dimensional scanning technologies, which can accurately measure the geometric shape and size of castings to ensure that they fully meet the design requirements and technical standards. Aviation castings must ensure high precision and high reliability because they are directly related to the safety and performance of aircraft. Precise shape detection devices can detect and identify any deviations, concavities, convexities or dimensional changes on the surface of castings, timely discover potential problems and correct them, so as to ensure that there are no structural or performance defects in the castings during use, thus guaranteeing the reliable operation of aircraft components and flight safety.

[0003] Traditional precise shape detection devices for investment casting castings with multi-stage overlapping sections for aviation use consist of several key parts. First, there are various sensors and detection devices, including optical measurement systems, laser rangefinders and surface roughness measuring instruments, which are used to accurately measure the size, shape and surface quality of castings. Secondly, there is a data acquisition and processing system, which is responsible for receiving and processing the data collected by sensors, calculating size and shape parameters, and evaluating surface quality. It usually includes a dedicated computer system and data processing software. The mechanical support structure provides stable support to ensure that the sensors can accurately measure and detect castings, including precise mechanical guide rails and fixed fixtures.

[0004] However, the problem of the single structure of the detection device in traditional precise shape detection devices for aviation castings has brought several significant adverse effects. First, since it takes a lot of time to replace measuring tools for the detection device, the production efficiency is significantly affected, resulting in project schedule delays.

[0030] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0031] Referring to Figure 1 and Figure 2 In an embodiment provided by the present invention: A device for accurately detecting the shape of a multi-stage lap section investment casting for aviation includes a base 1. A first hollow plate 2 is fixedly connected to the top of the base 1. A connecting column 7 is fixedly connected inside the first hollow plate 2. A clamping ring 9 is fixedly connected to the top of the connecting column 7. A first threaded rod 10 is rotatably connected inside the clamping ring 9. A turntable 8 is fixedly connected to the top of the first threaded rod 10. A first spring 11 is arranged at one end of the first threaded rod 10. A clamping column 12 is fixedly connected to one end of the first spring 11. A limiting ball 13 is arranged on the outer wall of the clamping column 12. A hollow column 14 is arranged on the outer wall of the limiting ball 13.

[0032] Specifically, during the operation of the device for accurately detecting the shape, first, by rotating the turntable 8, the driving force of the turntable 8 acts on the first threaded rod 10 at the bottom, causing it to start rotating. The first threaded rod 10 is connected to the clamping ring 9 inside, and the movement of the clamping ring 9 guides the first spring 11 at the bottom to start contracting. Subsequently, the pressure of the first spring 11 acts on the clamping column 12 at the bottom, pushing it to move. The movement of the clamping column 12 causes the limiting ball 13 on the outer wall to start moving, and the limiting ball 13 is ejected from the outer wall of the hollow column 14. Finally, the measuring tool can be installed and fixed on the top of the connecting column 7, achieving the effect of quickly replacing the measuring tool.

[0033] Referring to Figure 1 and Figure 3 On the top of the first hollow plate 2, a first fixing block 4 is fixedly connected. A fixing plate 17 is fixedly connected to the top of the first fixing block 4. A second fixing block 18 is fixedly connected to the bottom of the fixing plate 17. A first fixing column 5 is rotatably connected inside the first fixing block 4. A second threaded rod 16 is fixedly connected to one end of the first fixing column 5. A handle 15 is fixedly connected to one end of the second threaded rod 16. A connecting sleeve 19 is fixedly connected to the outer wall of the first fixing column 5. A second limiting pin 21 is fixedly connected to one side of the connecting sleeve 19. A third spring 20 is arranged on the outer wall of the second limiting pin 21. A clamping plate 22 is fixedly connected to one end of the third spring 20. A second fixing column 23 is rotatably connected inside the second fixing block 18. The clamping plate 22 is rotatably connected to the outer wall of the second fixing column 23, and the clamping plate 22 is rotatably connected inside the second fixing block 18.

[0034] Specifically, by rotating the handle 15, the handle 15 transmits force to the second threaded rod 16 on the side wall, causing it to start rotating. The second threaded rod 16 rotates inside the first fixed block 4, thereby affecting the rotation of the first fixed column 5 at one end. The movement of the first fixed column 5 guides the second limit pin 21 on one side to start rotating, and at the same time, the movement of the second limit pin 21 causes the external third spring 20 to start contracting. The pressure of the third spring 20 causes the clamping plate 22 on the side wall to start rotating, and the clamping plate 22 rotates inside the second fixed block 18. At the same time, the action of the connecting ring 19 fixes the first fixed column 5 and the second limit pin 21, thereby achieving a clamping effect on the ring body.

[0035] Reference Figure 1 A mold assembly is provided inside the first hollow plate 2, and the mold assembly is used to measure the effect of the sample. The mold assembly includes a template 24, the outer wall of the template 24 is fixedly connected to the inside of the first hollow plate 2, the side wall of the template 24 is fixedly connected to the limiting hole 6, and the top of the first hollow plate 2 is fixedly connected to the first limiting pin 3.

[0036] Specifically, by providing the limiting holes 6 and fixing them on the side walls of the template 24, and by making the design of the template 24 perfectly match the texture of the ring body, the effect of fitting the ring body is achieved.

[0037] Working principle: When using the shape precision detection device, first rotate the turntable 8, and the force of the turntable 8 drives the first threaded rod 10 at the bottom to rotate, and at the same time, the first threaded rod 10 is rotated and connected to the inside of the snap ring 9. At the same time, the movement of the snap ring 9 drives the first spring 11 at the bottom to contract, and then the force of the first spring 11 drives the bottom clamping column 12 to move, and then the movement of the clamping column 12 drives the limiting ball 13 on the outer wall, and the movement of the limiting ball 13 pushes it out of the outer wall of the hollow column 14, and then the measuring tool can be fixed on the top of the connecting column 7, so that the effect of quickly replacing the measuring tool is achieved, and then the limiting holes 6 and the template 24 are set, and the limiting holes 6 are evenly distributed and fixed on the side wall of the template 24, and the template 24 is connected to the ring body. The patterns will fit together, achieving the effect of the locking ring body, and then the handle 15 is turned, and the force of the handle 15 drives the second threaded rod 16 of the side wall to rotate, and at the same time, the second threaded rod 16 rotates inside the first fixing block 4, and then the force of the second threaded rod 16 drives the first fixing column 5 at one end to rotate, and at the same time, the force of the first fixing column 5 drives the second limiting pin 21 on one side to rotate, and at the same time, the rotation of the second limiting pin 21 drives the third spring 20 of my outer wall to contract, and at the same time, the force of the third spring 20 drives the clamping plate 22 of the side wall to rotate, and at the same time, the clamping plate 22 rotates inside the second fixing block 18, and at the same time, the first fixing column 5 and the second limiting pin 21 are fixed by the connecting ring 19, thereby achieving the effect of clamping the ring body.
