Description

Technical Field

[0001] This utility model relates to the field of tooling and fixture technology, specifically to an embedded multi-stage blade and flow channel milling clamping device. Background Technology

[0002] Embedded multistage blades are key components used in high-end equipment such as aero engines. Their design and processing technology require extremely high precision and stability. Embedded multistage blades are usually integrated into stators. According to a search, Chinese Patent Publication No. CN221984474U discloses an embedded multistage blade and flow channel milling clamping device. Its main function is to provide good clamping stability and a sufficiently large open processing space after clamping, which facilitates external equipment to process the stator blades and flow channels in one go, thus improving processing efficiency. However, in actual use, the process of clamping the stator is inconvenient and cumbersome, resulting in low clamping efficiency.

[0003] To address this issue, we propose an embedded multi-stage blade and flow channel milling clamping device. Utility Model Content

[0005] To achieve the above objectives, this utility model provides the following technical solution: an embedded multi-stage blade and flow channel milling clamping device, comprising a mounting base and a blade stator, characterized in that: a fixing block is fixedly connected to the top of the mounting base, and a clamping structure is provided inside the fixing block; a stabilizing block is fixedly connected to the bottom of the blade stator, and the stabilizing block and the fixing block are inserted into each other. The clamping structure includes a slider, which is slidably disposed inside the fixed block. A clamping spring is installed between the slider and the inner wall of the fixed block. A pull rod and a clamping block are fixedly connected to the outer wall of the slider, and a handle is fixedly connected to the outer wall of the pull rod.

[0006] Preferably, two clamping structures are symmetrically arranged inside the fixed block, and two connecting rods that are hinged to each other are installed between the two sliders.

[0007] Preferably, it also includes a stop screw, which is threadedly connected to the fixing block.

[0008] Preferably, it also includes a connecting block, which is rotatably connected to a stop screw. A movable rod is fixedly connected to the outer wall of the connecting block, and a limit rod is fixedly connected inside the movable rod. The limit rod is slidably installed inside the fixed block and is inserted into the slider.

[0009] Preferably, it also includes a rotary wrench, which is engaged with a locking set screw.

[0010] Compared with the prior art, this utility model provides an embedded multi-stage blade and flow channel milling clamping device, which has the following beneficial effects: This embedded multi-stage blade and flow channel milling clamping device, during the process of inserting the stabilizing block into the fixed block, allows the slider to drive the clamping block to clamp the stabilizing block under the action of the clamping spring. Furthermore, the action of the stop screw ensures that the stabilizing block has sufficient stability, enabling the rapid clamping of the blade stator. This greatly improves clamping efficiency and is simple to operate, making it convenient for practical use. Attached Figure Description

[0013] Example

[0014] Please see Figure 1-4 An embedded multi-stage blade and flow channel milling clamping device includes a mounting base 1 and a blade stator 2. A fixing block 3 is fixedly connected to the top of the mounting base 1. A clamping structure is provided inside the fixing block 3. A stabilizing block 4 is fixedly connected to the bottom of the blade stator 2. The stabilizing block 4 and the fixing block 3 are inserted into each other. The clamping structure includes a slider 5, which is slidably disposed inside the fixing block 3. A clamping spring 6 is installed between the slider 5 and the inner wall of the fixing block 3. A pull rod 7 and a clamping block 8 are fixedly connected to the outer wall of the slider 5. A handle 9 is fixedly connected to the outer wall of the pull rod 7.

[0015] After the stabilizing block 4 is inserted into the fixing block 3, the clamping spring 6 causes the slider 5 to drive the clamping block 8 to clamp the stabilizing block 4, thereby achieving the effect of clamping the blade stator 2. The operation is simple and can greatly improve the clamping efficiency. Furthermore, by pulling the handle 9, the slider 5 is moved under the connection of the pull rod 7, thereby causing the clamping block 8 to disengage from the stabilizing block 4, which facilitates the disassembly of the blade stator 2. The installation and disassembly efficiency is high and it is beneficial for practical use.

[0016] Please see Figure 2 and Figure 3 There are two clamping structures symmetrically arranged inside the fixed block 3, and two connecting rods 10 that are hinged to each other are installed between the two sliders 5.

[0017] The connecting rod 10 enables the two sliders 5 to move simultaneously, which facilitates the two clamping blocks 8 to clamp the stabilizing block 4 simultaneously, thereby improving the stability of the blade stator 2 after clamping.

[0018] Please see Figure 3 It also includes a stop screw 11, which is threadedly connected to the fixing block 3.

[0019] By rotating the stop screw 11, pressure can be applied to the stabilizer block 4, which can further improve the stability of the stabilizer block 4.

[0020] Please see Figure 3 It also includes a connecting block 12, which is rotatably connected to the stop screw 11. A moving rod 13 is fixedly connected to the outer wall of the connecting block 12. A limit rod 14 is fixedly connected inside the moving rod 13. The limit rod 14 is slidably installed inside the fixed block 3 and is inserted into the slider 5.

[0021] During the rotation of the stop screw 11, the connecting block 12 moves accordingly, thereby causing the moving rod 13 to drive the limiting rod 14 to insert into the interior of the slider 5, fixing the slider 5 and preventing the clamping block 8 from becoming loose.

[0022] Please see Figures 1-3 It also includes a rotary wrench 15, which is engaged with a stop screw 11.

[0023] The design of the rotary wrench 15 makes it easier to rotate the stop screw 11.

[0024] In summary, the working principle and process of this embedded multi-stage blade and flow channel milling clamping device are as follows: First, the mounting plate is fixed to the desired location using bolts. Then, the stabilizing block 4 at the bottom of the blade stator 2 is inserted into the fixed block 3. During this process, the clamping spring 6 clamps the stabilizing block 4. Then, by rotating the handle 9 to rotate the stop screw 11, the stabilizing block 4 becomes more stable, preventing it from shaking during processing. During this process, the limiting rod 14 is inserted into the slider 5 to fix it, preventing the clamping block 8 from loosening and further improving the stability of the stabilizing block 4. Therefore, this embedded multi-stage blade and flow channel milling clamping device facilitates quick clamping of the blade stator 2, and the blade stator 2 has high stability after clamping, which is beneficial for practical use.

[0025] The embodiments described above merely illustrate specific implementations of this utility model, and while the descriptions are detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
