Description

Technical Field

[0001] This application relates to the field of turning tooling technology, and in particular to a turning tooling for enhancing the rigidity of flexible cylindrical parts. Background Technology

[0002] Turning is an important machining process in the field of mechanical manufacturing, widely used in the forming and machining of various metallic and non-metallic materials. During turning, the stability of the workpiece clamping has a crucial impact on the machining quality. This is especially true in the machining of flexible cylindrical parts (bellows), where the material properties and structural characteristics place higher demands on fixture design.

[0003] When machining flexible cylindrical parts, if the clamping force of the fixture is too large, the flexible cylindrical parts are prone to deformation. If the clamping force is too small, the flexible cylindrical parts are prone to shaking during the machining process, thereby reducing the machining quality. Utility Model Content

[0004] To address the aforementioned technical problems, this application provides a turning fixture for enhancing the rigidity of flexible cylindrical parts.

[0005] This application provides a turning fixture for enhancing the rigidity of flexible cylindrical parts, which adopts the following technical solution:

[0006] A turning fixture for enhancing the rigidity of a flexible cylindrical component includes an inner support tube disposed inside the flexible cylindrical component and a spreading mechanism for spreading the inner support tube, wherein the inner support tube has a first opening.

[0007] By adopting the above technical solution, the inner support tube is set inside the flexible cylindrical part, providing internal support force and reducing deformation during clamping. The spreading mechanism is used to spread the inner support tube, allowing it to abut against the inner wall of the flexible cylindrical part, thereby enhancing its rigidity and improving its stability during turning, reducing wobbling and improving machining quality. The inner support tube provides stable support to the inner wall of the flexible cylindrical part, reducing deformation and further improving machining quality. The first opening facilitates the effective transmission of the spreading mechanism's force to all parts of the inner support tube, ensuring a uniform distribution of support.

[0008] Preferably, the flexible cylindrical component is fitted with an outer sleeve, and the outer sleeve has a second opening, and the outer sleeve is used to be clamped by a lathe.

[0009] By adopting the above technical solution, the outer sleeve increases the clamping force area of ​​the flexible cylindrical component, effectively dispersing the clamping force and preventing deformation due to excessive local stress. Simultaneously, the outer sleeve, in conjunction with the inner support tube, further improves the stability of the flexible cylindrical component during processing, reducing swaying and thus enhancing the processing quality.

[0010] Preferably, the extension direction of the first opening is parallel to the axis of the inner support tube, and the extension direction of the second opening is parallel to the axis of the outer sleeve tube.

[0011] By adopting the above technical solution, the first opening on the inner support tube extends along its axial direction, facilitating the effective transmission of the force of the spreading mechanism to all parts of the inner support tube and ensuring a uniform distribution of the support effect. The second opening on the outer tube extends along its axial direction, causing the outer tube to deform when clamped by external force. This, in turn, ensures that the clamping force of the clamping mechanism on the lathe is evenly applied to the flexible cylindrical part, further improving the stability of the flexible cylindrical part during processing, reducing swaying and deformation, and improving processing quality.

[0012] Preferably, the spreading mechanism includes a pushing block, a first guide inclined surface disposed on the side wall of the pushing block, a second guide inclined surface disposed on the inner wall of the inner support tube, and an adjusting component for adjusting the position of the pushing block. The first guide inclined surface and the second guide inclined surface are arranged parallel to each other. The adjusting component is used to drive the pushing block to slide along the second guide inclined surface. The pushing block has a frustum structure.

[0013] By adopting the above technical solution, the cooperation between the pushing block in the spreading mechanism and the first and second guide inclined surfaces effectively realizes the spreading action of the inner support tube. The design of the pushing block as a frustum structure allows it to apply radial force evenly to the inner support tube when sliding along the second guide inclined surface, thereby ensuring stable support inside the flexible cylindrical component. The setting of the adjustment component further improves the controllability of the spreading action, reduces the shaking phenomenon of the flexible cylindrical component during processing, and reduces the risk of deformation, thereby improving the processing quality.

[0014] Preferably, the adjustment assembly includes a limiting plate that abuts against one end of the inner support tube, an adjustment screw fixedly disposed in the center of the limiting plate, and a connecting hole opened in the center of the horizontal plane of the push block. The adjustment screw is threadedly connected to the push block through the connecting hole.

[0015] By adopting the above technical solution, the limiting plate abuts against one end of the inner support tube, effectively preventing the pushing block from detaching from the inner support tube. Simultaneously, the adjusting screw is threadedly connected to the pushing block through the connecting hole, enabling precise adjustment of the pushing block's position. This design allows the spreading mechanism to more stably spread the inner support tube, thereby better supporting the flexible cylindrical component, reducing deformation and swaying during processing, and further improving processing quality.

[0016] Preferably, the adjustment assembly includes a limiting plate that abuts against one end of the inner support tube, a cylinder fixedly disposed in the center of the limiting plate, a connecting hole opened in the center of the horizontal plane of the push block, and a threaded connecting rod. The threaded connecting rod is fixedly connected to the end of the cylinder away from the limiting plate, and the threaded connecting rod is threadedly connected to the push block through the connecting hole.

[0017] By adopting the above technical solution, the rotating limiting plate causes the threaded connecting rod to be threadedly connected to the pushing block through the connecting hole. Then, the cylinder drives the pushing block and the limiting plate to move closer to each other. Since the inner support tube limits the limiting plate, the pushing block slides inside the inner support tube, thereby quickly opening the inner support tube and improving the opening efficiency of the inner support tube.

[0018] Preferably, the connecting hole is located at the end of the push block with a smaller diameter.

[0019] By adopting the above technical solution, the connection hole is set at the end with the smaller diameter of the push block, so that the adjusting screw can be connected to the push block more stably, and at the same time, it is convenient for the adjusting component to accurately control the position of the push block.

[0020] Preferably, the diameter of the limiting plate is greater than the inner diameter of the inner support tube and less than the outer diameter of the inner support tube.

[0021] By adopting the above technical solution, the diameter of the limiting plate is larger than the inner diameter of the inner support tube, allowing the limiting plate to stably abut against one end of the inner support tube, preventing the adjusting component from disengaging during the movement of the pushing block, thereby ensuring the working reliability of the spreading mechanism. At the same time, the diameter of the limiting plate is smaller than the outer diameter of the inner support tube, avoiding interference between the limiting plate and the external structure of the inner support tube, ensuring the normal assembly and use of the entire turning fixture.

[0022] In summary, this application has the following beneficial technical effects:

[0023] 1. The inner support tube is opened by the opening mechanism to support the inside of the flexible cylindrical part. In conjunction with the lathe clamping mechanism, the shaking phenomenon of the flexible cylindrical part during the processing is effectively reduced.

[0024] 2. The combined use of the inner support tube and the spreading mechanism avoids the problem of deformation of flexible cylindrical parts caused by excessive clamping force, thereby improving the processing quality;

[0025] 3. The outer sleeve increases the clamping force area of ​​the flexible cylindrical component, and works in conjunction with the inner support tube to further improve the stability of the flexible cylindrical component during processing. Attached Figure Description

[0031] The following is in conjunction with the appendix Figures 1-4 This application will be described in further detail.

[0032] Embodiments 1-2 of this application disclose a turning tooling for enhancing the rigidity of flexible cylindrical parts.

[0033] Example 1

[0034] Reference Figure 1 , Figure 2 and Figure 3 A turning fixture for enhancing the rigidity of a flexible cylindrical component includes an inner support tube 2 disposed inside the flexible cylindrical component 1 and a spreading mechanism 3 for spreading the inner support tube 2. The inner support tube 2 has a first opening 21.

[0035] The flexible cylindrical component 1 is fitted with an outer sleeve 4, which has a second opening 41 for being clamped by a lathe. The first opening 21 extends parallel to the axis of the inner support tube 2, and the second opening 41 extends parallel to the axis of the outer sleeve 4.

[0036] The spreading mechanism 3 includes a pushing block 31, a first guide slope 32 disposed on the side wall of the pushing block 31, a second guide slope 33 disposed on the inner wall of the inner support tube 2, and an adjustment component 34 for adjusting the position of the pushing block 31. The first guide slope 32 and the second guide slope 33 are arranged parallel to each other. The adjustment component 34 is used to drive the pushing block 31 to slide along the second guide slope 33. The pushing block 31 has a frustum structure.

[0037] The adjusting assembly 34 includes a limiting plate 341 that abuts against one end of the inner support tube 2, an adjusting screw 342 fixedly disposed in the center of the limiting plate 341, and a connecting hole 343 opened in the center of the horizontal plane of the pushing block 31. The adjusting screw 342 is threadedly connected to the pushing block 31 through the connecting hole 343. The connecting hole 343 is located at the end of the pushing block 31 with a smaller diameter. The diameter of the limiting plate 341 is larger than the inner diameter of the inner support tube 2 and smaller than the outer diameter of the inner support tube 2.

[0038] When installing the turning fixture to enhance the rigidity of the flexible cylindrical component, first insert the inner support tube 2 into the flexible cylindrical component 1, then place the limiting plate 341 at one end of the inner support tube 2, and insert the pushing block 31 into the inner support tube 2 from the other end. By rotating the adjusting screw 342, the adjusting screw 342 is inserted into the connecting hole 343. The operator manually supports the pushing block 31 to restrict its rotation. Continue to rotate the adjusting screw 342 to make it penetrate deeper into the connecting hole 343, thereby reducing the distance between the pushing block 31 and the limiting plate 341. The inner support tube 2 limits the limiting plate 341, thereby causing the pushing block 31 to slide inside the inner support tube 2, which in turn causes the inner support tube 2 to be opened. After the inner support tube 2 is opened, it provides support for the flexible cylindrical part 1. Then, the outer tube 4 is sleeved on the outside of the flexible cylindrical part 1, which completes the connection between the turning tool that enhances the rigidity of the flexible cylindrical part and the flexible cylindrical part 1. By clamping the outer tube 4 through the clamping mechanism on the lathe, stable turning processing of the flexible cylindrical part 1 can be achieved.

[0039] Example 2

[0040] Reference Figure 4 The difference from Embodiment 1 is that the adjustment component 34 includes a limiting plate 341 that abuts against one end of the inner support tube 2, a cylinder 344 fixedly disposed in the center of the limiting plate 341, a connecting hole 343 opened in the center of the horizontal plane of the push block 31, and a threaded connecting rod 345. The threaded connecting rod 345 is fixedly connected to the end of the cylinder 344 away from the limiting plate 341, and the threaded connecting rod 345 is threadedly connected to the connecting hole 343.

[0041] When installing a turning fixture to enhance the rigidity of a flexible cylindrical component, a limiting plate 341 is placed at one end of the inner support tube 2, and a pushing block 31 is inserted into the inner support tube 2 from the other end. By rotating the limiting plate 341, the threaded connecting rod 345 is threadedly connected to the connecting hole 343. Then, the cylinder 344 drives the pushing block 31 to move closer to the limiting plate 341, thereby opening the inner support tube 2. This eliminates the need for manual support of the pushing block 31, thus improving the opening efficiency of the inner support tube 2.

[0042] The implementation principle of a turning fixture for enhancing the rigidity of a flexible cylindrical part according to an embodiment of this application is as follows: the inner support tube 2 is opened by the spreading mechanism 3, so that the inner support tube 2 fits tightly against the inner wall of the flexible cylindrical part 1, thereby providing internal support for the flexible cylindrical part 1. At the same time, the outer sleeve 4 is fitted on the outside of the flexible cylindrical part 1, increasing the clamping force area and effectively reducing the shaking phenomenon of the flexible cylindrical part 1 during processing. This double support design not only solves the deformation problem caused by excessive clamping force, but also overcomes the shaking problem caused by insufficient clamping force, significantly improving the processing quality of the flexible cylindrical part 1. In addition, the introduction of the adjustment component 34 makes the operation of the spreading mechanism 3 more convenient, further enhancing the practicality of the overall fixture.

[0043] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
