[0030] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.
[0031] Refer to Figure 1 - Figure 4, an embodiment provided by the present utility model: a correction tool for a fan-shaped complex structural part of an aero-engine, including a base 9, a fixed base 18 is fixedly connected to the rear side of the base 9, an L-shaped plate 2 is fixedly connected to the middle side of the top of the fixed base 18, a cylinder 3 is fixedly connected to the upper part inside the L-shaped plate 2, an upper pressure plate 4 is fixedly connected to the output end of the cylinder 3, two baffles 7 are arranged on the top of the base 9, a middle baffle 8 is arranged between the two baffles 7, a middle baffle 8 is arranged on the right side of the top of the base 9, a top-out mechanism is arranged inside the baffle 7, and the top-out mechanism is used for top-out of the fan-shaped structure. A plurality of stay ropes 20 are slidably connected inside the base 9, a thin shell 21 is slidably connected to the outside of the stay ropes 20, one end of the stay rope 20 is fixedly connected to a moving plate 1, a plugging rod 19 is fixedly connected to one side of the moving plate 1, a second spring 5 is sleeved on the outside of the stay rope 20, two mounting blocks 17 are fixedly connected to the bottom of the baffle 7, and two positioning pins 6 are fixedly connected to the bottom of the middle baffle 8.
[0032] Specifically, during the operation process, first, under the action of driving the cylinder 3, the upper pressure plate 4 is urged to move downward, so as to precisely adjust the required correction tool. When the correction work is completed, pull the handle 10, which will further drive the moving plate 1 and the plugging rod 19 to move synchronously. This movement causes the second spring 5 to be compressed until the plugging rod 19 completely exits the internal space of the mounting block 17. At this time, the disassembly process of the baffle 7 is completed. Subsequently, the user can replace the baffle 7 with different lengths according to needs. Finally, use the top-out mechanism to safely eject the corrected tool to prevent any damage to the tool during the disassembly process.
[0033] Refer to Figure 2 , the top-out mechanism includes a rotating rod 11 and a combined rod 13. The outside of the rotating rod 11 is rotatably connected inside the middle baffle 8, the outside of the combined rod 13 is slidably connected inside the middle baffle 8, one end of the rotating rod 11 is fixedly connected to a cam 12, two fixed rods 14 are fixedly connected to the outside of the combined rod 13, one end of the fixed rod 14 away from the combined rod 13 is fixedly connected to a slider 15, and a first spring 16 is fixedly connected to the bottom end of the slider 15.
[0034] Specifically, the operator can rotate the rotating rod 11, and this action will cause the cam 12 to rotate accordingly. As the cam 12 rotates, the combined rod 13 starts to move upward, further driving the fixed rod 14 and the slider 15 to rise synchronously. During this process, the slider 15 will slide smoothly inside the middle baffle 8. At the same time, the first spring 16 is stretched due to the upward movement of the slider. When the rotating rod 11 is released, at this time, under the action of the first spring 16, the 15, the combined rod 13 and the fixed rod 14 move downward to return to their original positions.
[0035] Refer to Figure 1 - Figure 4, at one end of two adjacent draw ropes 20 away from the mounting block 17, a handle 10 is fixedly connected. One end of the second spring 5 is fixedly connected to one side of the moving plate 1, and the other end of the second spring 5 is fixedly connected to the inner wall of the thin shell 21. The outer side of the moving plate 1 is slidably connected inside the thin shell 21, the outer side of the insertion rod 19 is slidably connected inside the thin shell 21, the insertion rod 19 is inserted inside the mounting block 17, the inner bottom wall of the base 9 is fixedly connected with a plurality of thin shells 21, the bottom of the middle baffle 8 is fixedly connected to the middle side of the top of the base 9, the outer side of the positioning pin (6) is slidably connected inside the upper pressing plate 4, the bottom end of the first spring 16 is fixedly connected to the inner wall of the middle baffle 8, and the combined rod 13 and the cam 12 are in mutual contact.
[0036] Specifically, the draw rope 20 is used to operate the movement of the moving plate 1. The user of the handle 10 controls the movement of the draw rope 20 through it, and the second spring 5 is responsible for adjusting the movement of the moving plate 1. The moving plate 1 is slidably connected inside the thin shell 21 and moves with the pulling force of the second spring 5. The thin shell 21 provides the necessary space and support. The outer side of the insertion rod 19 is connected to the thin shell 21 and extends into the mounting block 17 for installation and disassembly. The base 9 is internally provided with a plurality of thin shells 21 to enhance the structural stability. The bottom of the middle baffle 8 is fixed at the center of the top of the base 9. The positioning pin 6 is connected to the upper pressing plate 4. The positioning pin 6 controls the movement range and trajectory of the upper pressing plate 4. The first spring 16 is fixed inside the middle baffle 8 for cooperating with the ejection of the tooling. The combined rod 13 and the cam 12 are in mutual contact to form a linkage mechanism.
[0037] Working principle: During use, the driving cylinder 3 is driven to drive the upper pressing plate 4 to move downward to correct the required correction tooling. After the correction is completed, at this time, the handle 10 is pulled, which drives the moving plate 1 and the insertion rod 19 to move, so that the second spring 5 is compressed until the insertion rod 19 completely leaves the inside of the mounting block 17. At this time, the disassembly of the baffle 7 is completed. At this time, different lengths of the baffle 7 can be replaced according to requirements. At this time, the rotating rod 11 can be rotated, which drives the cam 12 to rotate, thereby driving the combined rod 13 to move upward, and then driving the fixed rod 14 and the slider 15 to move upward. At this time, the slider 15 slides inside the middle baffle 8, and at the same time, the first spring 16 is stretched, so as to eject the corrected tooling to avoid damage.
