Description

Technical Field

[0001] This utility model relates to the field of lathe tool technology, and more specifically, to a vibration-damping alloy lathe tool. Background Technology

[0002] In the field of machining, lathe tools are key cutting tools whose performance directly affects machining quality and efficiency. However, existing lathe tools commonly suffer from tool tip damage due to tool vibration during machining, which severely restricts the improvement of machining accuracy and the extension of tool life.

[0003] Currently, two main methods of vibration reduction are passive and active. Passive vibration reduction technology primarily employs principles such as damping and friction damping, using built-in damping materials or friction pairs to dissipate vibration energy. While this method has a simple structure, its vibration reduction effect is highly sensitive to ambient temperature and cutting load, resulting in insufficient reliability. Active vibration reduction technology uses sensors to detect chatter signals in real time and uses actuators to generate counteracting forces to suppress vibration. Although this method offers better vibration reduction, it is more complex and costly. It requires high-precision sensors, real-time controllers, and power actuators, which not only increases the complexity of the tooling system but also significantly raises the operating costs.

[0004] Therefore, a vibration-damping alloy turning tool is proposed to solve the above problems. Utility Model Content

[0006] To achieve the above objectives, the present invention provides the following technical solution: A vibration-damping alloy turning tool includes a shank portion, a rod length direction along the length direction of the shank portion, a shank thickness direction perpendicular to the rod length direction, and a set of vibration-damping parts are respectively provided on both ends of the shank portion along the thickness direction of the shank portion, the vibration-damping parts being made of vibration-damping alloy material.

[0007] The present invention is further configured such that: the handle portion is provided with a blade portion on one side along the length direction of the rod, the blade portion has a blade thickness direction perpendicular to the length direction of the rod, the blade thickness direction is parallel to the thickness direction of the handle portion, the blade portion has a blade thickness along the blade thickness direction, the handle portion has a handle thickness along the handle thickness direction, and the blade thickness is greater than the handle thickness.

[0008] The present invention is further configured such that: the vibration damping part has an alloy thickness following the thickness direction of the handle, and the sum of the two sets of alloy thicknesses and the handle thickness is consistent with the thickness of the blade.

[0009] The present invention is further configured such that: a blade head is provided on the side of the blade body away from the handle part along the length direction of the rod, the blade head has a blade thickness direction perpendicular to the length direction of the rod, the blade thickness direction is parallel to the thickness direction of the blade body, and a cutting edge is provided on the blade head along the blade thickness direction.

[0010] The present invention is further configured such that: the handle portion has multiple sets of handle threaded holes on both ends along the thickness direction of the handle, and the multiple sets of handle threaded holes on both ends are symmetrically arranged along the length direction of the rod; the vibration damping portion has multiple sets of vibration damping holes in the thickness direction of the handle, and the vibration damping holes correspond one-to-one with the handle threaded holes.

[0011] Another embodiment of this utility model is configured such that the outer wall of the handle portion and the inner wall of the vibration damping portion are connected by adhesive injection.

[0012] In summary, this application includes at least one of the following beneficial technical effects: 1. By adding a vibration damping unit, tool vibration during machining can be reduced, effectively improving machining accuracy and reducing machining wear; 2.

[0014] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0015] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0016] Example 1, please refer to Figure 1-2 The present invention provides the following technical solution: Specifically, it refers to a vibration-damping alloy turning tool, see [link / reference]. Figure 1-2 The device includes a handle portion 3, with a rod extending along its length and a handle thickness perpendicular to the rod. A set of vibration damping portions 4, made of vibration damping alloy material, is provided on each end of the handle portion 3 along its thickness. A blade portion 2, perpendicular to the rod, is provided on one side of the handle portion 3 along its length. The blade thickness is parallel to the handle thickness, and both the blade portion 2 and the handle portion 3 have a blade thickness, with the blade thickness exceeding the handle thickness. The vibration damping portions 4 have an alloy thickness along the handle thickness direction. The sum of the blade thickness and the handle thickness is the same as the blade body thickness. A blade head 1 is provided on the side of the blade body 2 away from the handle 3, following the length direction of the rod. The blade head 1 has a blade thickness direction perpendicular to the length direction of the rod, and this blade thickness direction is parallel to the blade body thickness direction. A cutting edge 11 is provided on the blade head 1 along the blade thickness direction. Multiple sets of handle threaded holes 31 are respectively opened on both ends of the handle 3 along the handle thickness direction, and these multiple sets of handle threaded holes 31 are symmetrically arranged along the length direction of the rod. Multiple sets of vibration damping holes 41 are opened on the handle thickness direction of the vibration damping part 4, and each vibration damping hole 41 corresponds one-to-one with a handle threaded hole 31. The handle threaded holes 31 and vibration damping holes 41 are fixed together by countersunk bolts. Experiments were conducted on the lathe tools with and without vibration damping part 4. Taking the DCLNR2525M12 type lathe tool holder as an example, the alloy thickness of vibration damping part 4 is 3mm, the cutting edge 11 is a 45-degree carbide lathe tool tip, and the machining object is Cr42mov type steel with a diameter of 50mm and a length of 100mm. The specific experimental steps are as follows: S1. Fix the above-mentioned workpiece to the lathe spindle with a single-sided clamping method, set the axial feed and perform cutting until the diameter is reduced to 30mm and the machining process is terminated. S2. Number the workpiece and the cutting tool; S3. Use a profilometer to detect the surface roughness of the workpiece; measure the tool wear using a microscope.

[0017] Experiments were conducted on the original lathe tool and the lathe tool with vibration damping part 4 added using the above method. The corresponding surface roughness, tool wear, and comparative data of the original lathe tool and the lathe tool with vibration damping part 4 added were obtained, as shown in the table below:

[0018] Experiments show that the cutting tool equipped with vibration damping part 4 has higher machining accuracy and less machining wear than the original cutting tool.

[0019] Example 2 differs from Example 1 only in that the tool holder threaded hole 31 and the vibration damping hole 41 are not opened. The outer wall of the tool holder 3 and the inner wall of the vibration damping part 4 are connected by glue injection. This reduces the problem of reduced structural strength caused by opening holes and is more suitable for installing the vibration damping part 4 on small lathe tools.

[0020] Obviously, the embodiments described above are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.
