Description

Technical Field

[0001] This utility model relates to the field of milling technology, and more specifically, to a vibration damping milling cutter sleeve. Background Technology

[0002] As the core cutting tool in milling, the performance of the milling cutter directly affects the machining quality and efficiency. With the increasing demands for machining accuracy and efficiency in fields such as machinery manufacturing and aerospace, milling cutters face increasingly severe challenges in environmental adaptability.

[0003] In complex machining environments, milling cutters are primarily affected by two types of vibration: forced vibration and self-excited vibration. Forced vibration originates from external factors such as machine tool spindle imbalance and loose clamping, and its frequency is usually related to the rotational speed. Self-excited vibration, on the other hand, stems from chattering during the cutting process and is characterized by high frequency and significant detrimental effects. The combined effect of these two types of vibration significantly accelerates tool wear.

[0004] Therefore, a vibration-damping milling cutter sleeve is proposed to solve the above problems. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a vibration damping milling cutter sleeve that improves the vibration damping function and extends the service life of the milling cutter.

[0006] To achieve the above objectives, the present invention provides the following technical solution: A vibration-damping end mill sleeve includes a sleeve column, which is a hollow structure. The sleeve column has a rod-length direction along its axis. Multiple sets of first adapting grooves and multiple sets of second adapting grooves are formed around the rod-length direction on the outer wall of the sleeve column. The first and second adapting grooves are staggered. The vibration-damping end mill sleeve is made of a vibration-damping alloy material.

[0007] The present invention is further configured such that: the first adapting groove is provided perpendicular to the length direction of the rod and penetrates through the outer wall of the sleeve column, and the second adapting groove is provided perpendicular to the length direction of the rod and penetrates through the outer wall of the sleeve column.

[0008] The present invention is further configured such that: the sleeve column has a column height along the length direction of the rod, the first adapting groove has a first slot depth along the length direction of the rod, the first slot depth is not less than half of the column height, and the second adapting groove has a second slot depth along the length direction of the rod, the second slot depth is not less than half of the column height.

[0009] The present invention is further configured such that: the outer circle direction of the rod is circumferentially following the outer wall of the sleeve column; the first adapting groove has a first slot width circumferentially following the outer circle direction of the rod; the second adapting groove has a second slot width circumferentially following the outer circle direction of the rod; and the first slot width is consistent with the second slot width.

[0010] In summary, this application includes the following beneficial technical effects: 1. The vibration-damping end mill sleeve made of vibration-damping alloy material solves the problem of end mill vibration during machining and improves the end mill's service life. By opening the first and second adaptation slots, the compatibility problem of the chuck is solved, that is, the slight difference in the outer wall diameter of different end mills of the same model causes a gap between the end mill and the chuck, which prevents normal machining, thus improving the compatibility of the chuck.

[0012] 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.

[0013] 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.

[0014] For examples, please refer to Figure 1-2 The present invention provides the following technical solution: Specifically, it refers to a vibration-damping milling cutter sleeve, see [link / reference]. Figure 1The vibration-damping end mill sleeve 1 includes a sleeve column 11, which is a hollow structure. Following the axis of the sleeve column 11, it has a rod-length direction. Multiple sets of first adapting grooves 12 and multiple sets of second adapting grooves 13 are formed around the outer wall of the sleeve column 11 along the rod-length direction. The first adapting grooves 12 and second adapting grooves 13 are staggered. The vibration-damping end mill sleeve 1 is made of a vibration-damping alloy material. The first adapting grooves 12 are perpendicular to the rod-length direction and penetrate the outer wall of the sleeve column 11, and the second adapting grooves 13 are perpendicular to the rod-length direction and penetrate the outer wall of the sleeve column 11. The sleeve column 11 has a column height along the length direction of the rod, the first adapting groove 12 has a first groove depth along the length direction of the rod, the first groove depth is not less than half of the column height, and the second adapting groove 13 has a second groove depth along the length direction of the rod, the second groove depth is not less than half of the column height; the sleeve column 11 has a rod outer circle direction along the outer wall circumference direction, the first adapting groove 12 has a first groove width along the outer circle direction of the rod, and the second adapting groove 13 has a second groove width along the outer circle direction of the rod, the first groove width and the second groove width are the same; See Figure 2 When installing the vibration damping milling cutter sleeve 1, it is also necessary to use it in conjunction with the chuck 2 and the milling cutter 3. The milling cutter 3 is inserted into the inner wall of the vibration damping milling cutter sleeve 1, and the chuck 2 is sleeved on the outer wall of the vibration damping milling cutter sleeve 1. The milling function is realized by connecting the chuck 2 to the machine tool spindle. The vibration damping end mill sleeve 1 made of the aforementioned vibration damping alloy material solves the problem of the end mill 3 vibrating during the machining process, thus improving the end mill's service life. By opening the first adaptation groove 12 and the second adaptation groove 13, the compatibility problem of the chuck 2 is solved, that is, the slight difference in the outer wall diameter of end mills 3 of the same model causes a gap between the end mill 3 and the chuck 2, making it impossible to machine normally, thus improving the compatibility of the chuck 2.

[0015] An experiment was conducted on the above device, using a milling cutter 3 with a diameter of 8mm and a hardness of 45 degrees as the experimental object. The milling cutter 3 used a BT40-ER32-100L model cutter shank and vibration damping milling cutter sleeves 1 with thicknesses of 0.5mm, 0.8mm, and 1.0mm. A piece of 42CrMo steel measuring 200mm × 200mm × 60mm was machined. The specific machining steps were as follows: S1. Install the milling cutter 3 into the chuck 2 and perform milling until a groove with a depth of 6mm, a width of 10mm, and a length of 200mm is machined. S2. Install the new milling cutter 3 and the vibration damping milling cutter sleeve 1 into the chuck 2 to mill the steel. S3. Replace with another type of vibration damping end mill sleeve 1 and end mill 3 and repeat steps S2-S3 until all types of vibration damping end mill sleeve 1 have been tested. S4. Inspect the wear condition of each of the above-mentioned milling cutters 3.

[0016] The relationship between the thickness of the vibration-damping end mill sleeve 1 and its wear condition can be obtained through the above experimental steps, as shown in the table below:

[0017] The data above shows that by setting the vibration damping sleeve 1, tool vibration can be effectively reduced, tool tip wear of the milling cutter 3 can be reduced, and tool life can be improved.
