[0025] The embodiments of this application are described in detail below. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this application, and should not be construed as limiting this application.

[0026] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

[0027] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the application.

[0028] Some embodiments of this application are described in detail. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0029] Please see Figure 1 This application provides a cutting tool assembly 100 for cutting the surface of a workpiece 200 to obtain holes 210 of different diameters. The cutting tool assembly 100 includes a tool holder 20, a connecting assembly 30, an adjusting assembly 40, and a cutting insert 50. The tool holder 20 is fixedly connected to one end of the connecting assembly 30, and the connection direction between the tool holder 20 and the connecting assembly 30 is a first direction X. The adjusting assembly 40 includes a first adjusting member 41 and a second adjusting member 42. The second adjusting member 42 is connected to the other end of the connecting assembly 30 opposite to the tool holder 20. The second adjusting member 42 is movably connected to the first adjusting member 41 and configured to move relative to the first adjusting member 41 and the connecting assembly 30 along a second direction Y perpendicular to the first direction X. The cutting insert 50 is detachably mounted to the second adjusting member 42 and can move with the second adjusting member 42 relative to the connecting assembly 30. This application provides a second adjusting member 42 that is slidably connected to the connecting assembly 30, and the cutting blade 50 is mounted on the second adjusting member 42. As the second adjusting member 42 slides relative to the connecting assembly 30, the distance between the cutting blade 50 and the central axis of the tool holder 20 also changes. In other words, the machining radius and / or machining range of the cutting blade 50 can be adjusted. Therefore, holes 210 of different sizes can be cut on the workpiece 200, which improves machining efficiency, reduces the frequency of changing the cutting blade 50, reduces labor costs, and greatly improves product quality.

[0030] In this embodiment, the cutting tool assembly 100 further includes a tool holder clamp 10, in which the tool shank 20 is mounted. The diameter of the tool shank 20 is 16mm, therefore the diameter of the tool holder clamp 10 at the mounting point for the tool shank 20 is also 16mm. In some other embodiments, the diameter of the tool shank 20 may include, but is not limited to, 16mm, and the corresponding diameter at the mounting point for the tool shank 20 will also change accordingly, as long as it meets the requirements of this application. The tool shank 20 in this application is detachably mounted to the tool holder clamp 10, which enhances the versatility of the cutting tool assembly 100 and makes it more convenient to use after mounting the tool holder clamp 10.

[0031] In this embodiment, the blade 50 is detachably fixed to the adjusting assembly 40 by a first fastener 70. This application does not limit the specific type of the first fastener 70, as long as it meets the requirements of this application.

[0032] Please see Figure 1 , Figure 2 and Figure 3 The connecting assembly 30 includes a first connecting portion 31 and a second connecting portion 32. One end of the first connecting portion 31 is fixedly connected to the tool holder 20. The second connecting portion 32 is connected to the other end of the first connecting portion 31 away from the tool holder 20. The surface of the second connecting portion 32 facing the second adjusting member 42 is provided with a first sliding groove 321. The second adjusting member 42 is slidably connected to the first sliding groove 321. Due to the sliding of the second adjusting member 42, the position of the blade 50 fixed on the second adjusting member 42 relative to the surface of the workpiece 200 also changes accordingly. This allows for the cutting of holes 210 of different sizes, improving processing efficiency, reducing the frequency of changing the blade 50, and lowering labor costs. In addition, it can prevent the second adjusting member 42 from wobbling back and forth along the rotation direction of the cutting tool assembly 100 during high-speed rotation, thereby affecting the quality of the hole 210. It can also prevent the second adjusting member 42 from falling off the cutting tool assembly 100, reducing certain safety hazards.

[0033] Please see Figure 1 , Figure 2 and Figure 3 The first adjusting member 41 includes a mounting end 411 and an adjusting end 412, with the mounting end 411 connected to the second connecting portion 32. The end of the second adjusting member 42 facing the second connecting portion 32 includes a first guide block 424 extending along the second direction Y and an adjusting screw 80. The first guide block 424 forms a sliding hole 422 facing the second connecting portion 32. The adjusting end 412 is at least partially received in the sliding hole 422. The adjusting screw 80 is movably connected between the first guide block 424 and the adjusting end 412 along the second direction Y, and the adjusting screw 80 is used to drive the first guide block 424 to move relative to the adjusting end 412.

[0034] In this embodiment, at least a portion of the mounting end 411 is fixed within the mounting hole 323 of the second connecting portion 32. The end face 4121 of the adjusting end 412 abuts against the stepped surface 4221 of the sliding hole 422, and at least a portion of the adjusting screw 80 is movably connected within the adjusting hole 41221 of the side surface 4122 of the adjusting end 412. The inner diameter of the adjusting hole 41221 is larger than the outer diameter of the adjusting screw 80, so that they do not interfere with each other when they move relative to each other. In this application, at least a portion of the adjusting screw 80 is movably disposed within the sliding hole 422 along the second direction Y. By adjusting the length of the adjusting screw 80 entering the sliding hole 422 along the second direction Y, the relative position of the first guide block 424 and the first sliding groove 321 is adjusted. This application does not limit the specific type of the adjusting screw 80; for example, it can be a fixing pin, as long as it meets the requirements of this application.

[0035] In this embodiment, the second adjusting member 42 further includes a second sliding groove 421. The second sliding groove 421 is disposed on the surface of the first guide block 424 facing the second connecting portion 32, and along the first direction X, the orthographic projection of the first sliding groove 321 and the orthographic projection of the second sliding groove 421 at least partially overlap. This design allows the first guide block 424 to slide relative to the second connecting portion 32, and the blade 50 fixed on the first guide block 424 of the second adjusting member 42 also slides accordingly. The position of the blade 50 relative to the surface of the workpiece 200 changes accordingly, which is beneficial for cutting holes 210 of different sizes, improving processing efficiency, reducing the frequency of changing the blade 50, and reducing labor costs. In addition, it also prevents the second adjusting member 42 from shaking due to the high-speed rotation of the cutting tool assembly 100, thereby affecting the quality of the hole 210.

[0036] Please see Figure 1 , Figure 2 and Figure 3 In this embodiment, the second connecting part 32 is provided with a first positioning line 322, and the second adjusting member 42 is provided with a first scale 423. The first positioning line 322 is used to align with the first scale 423 to determine the relative position of the second connecting part 32 and the second adjusting member 42. This design can precisely control the relative position of the second connecting part 32 and the second adjusting member 42, and precisely control the position of the blade 50 relative to the surface of the workpiece 200 to be cut, so as to prepare holes 210 of different sizes (diameters).

[0037] Please see Figure 1 , Figure 2 and Figure 3In this embodiment, the adjusting assembly 40 further includes an anti-slip groove 43 extending along the first direction X, and the blade 50 is detachably fixed to the anti-slip groove 43. This application aims to increase the friction between the blade 50 and the second adjusting assembly 42 by providing the anti-slip groove 43 on the second adjusting member 42 and detachably fixing the blade 50 to the anti-slip groove 43, thereby further reinforcing the blade 50 and preventing it from shaking during the high-speed rotation of the cutting tool assembly 100, thus never affecting the quality of the hole 210.

[0038] Please see Figures 4 to 6 In this embodiment, the blade 50 includes a blade body 51 and a cutting body 52 connected to the blade body 51. The cutting body 52 includes a main body 521 and a bottom cutting edge 522 connected to the main body 521. The blade 50 has a first surface 53. The first surface 53 includes a first region 531 located in the blade body 51, a second region 532 located in the main body 521, and a third region 533 located in the bottom cutting edge 522. The first region 531 and the second region 532 form a first included angle θ, and the third region 533 forms a second included angle (not shown) with the surface of the workpiece 200 to be cut. The first included angle θ is 180.75 degrees, and the second included angle (not shown) is 2 degrees. This application sets a first included angle θ of 180.75 degrees between the first region 531 of the cutter body 51 and the second region 532 of the main body 521, and a second included angle (not shown) of 2 degrees between the third region 533 of the bottom cutting edge 522 and the surface of the workpiece 200. The purpose of this design is to prevent deformation of the workpiece 200 surface when the cutting tool assembly 100 cuts it. The 2-degree second included angle (not shown) reduces the resistance between the third region 533 of the bottom cutting edge 522 and the surface of the workpiece 200, while also reducing wear on the bottom cutting edge 522 on the workpiece 200 surface during high-speed rotation of the cutting tool assembly 100.

[0039] Please see Figure 2 Figure 3 In this embodiment, the blade 50 also includes a protrusion 54, which is located on the other side of the blade body 51 away from the first region 531. The protrusion 54 is located in the anti-slip groove 43. This design strengthens the fixation between the blade 50 and the second adjusting member 42, preventing the blade 50 from shaking during the high-speed rotation of the cutting tool assembly 100, thus never affecting the quality of the hole 210.

[0040] Please see Figures 4 to 6In this embodiment, a groove 523 is provided at one end of the body 521 near the bottom cutting edge 522. The inner surface 5231 of the groove 523 is an arc surface with a radius of 0.15mm. The groove 523 is designed to allow the chips generated by the cutting tool assembly 100 when cutting the surface of the workpiece 200 to be discharged in a timely manner, ensuring the stability and safety of the cutting process. It also avoids wear of the cutting tool assembly 100 and problems affecting the quality of the hole 210.

[0041] Please see Figure 4 and Figure 5 In this embodiment, the cutting body 52 further includes a chipping edge 524, which is connected to the bottom cutting edge 522. The chipping edge 524 has a rounded corner with a radius of 0.3 mm. By setting the chipping edge 524 with a radius of 0.3 mm, this application helps to reduce the probability of burrs appearing on the surface of the hole 210, thereby making the surface finish of the prepared blanking hole 210 higher.

[0042] Please see Figure 4 In this embodiment, there are two cutting bodies 52, which are located diagonally on the cutter body 51. This design allows the insert 50 to be used on multiple sides, extending its service life and reducing economic costs.

[0043] Please see Figure 1 The cutting tool assembly 100 also includes a dynamic balancing ring device 60, which includes a dynamic balancing ring 61 and an adjusting screw 62. The dynamic balancing ring 61 is sleeved outside the first connecting part 31, and the adjusting screw 62 is adjustablely connected to the dynamic balancing ring 61. Considering that during the high-speed rotation of the cutting tool assembly 100, the weight of the cutting tool 50 will cause the cutting tool assembly 100 to tilt towards the side where the cutting tool 50 is installed, this application installs the adjusting screw 62 on the side of the cutting tool assembly 100 without the cutting tool to control the relative displacement of the adjusting screw 62 in the dynamic balancing ring 61, thereby ensuring the force balance of the cutting tool assembly 100 during high-speed rotation, improving the surface finish and flatness of the hole 210, and further improving the quality of the hole 210.

[0044] The cutting tool assembly 100 described above is provided with a second adjusting member 42 that is slidably connected to the connecting assembly 30, and the cutting tool 50 is installed on the second adjusting member 42. As the second adjusting member 42 slides relative to the connecting assembly 30, the distance between the cutting tool 50 and the central axis of the tool holder 20 also changes. That is to say, the machining radius and / or machining range of the cutting tool 50 can be adjusted. Therefore, it can cut holes 210 of different sizes, improve machining efficiency, reduce the frequency of changing the cutting tool 50, reduce labor costs, and greatly improve the quality of the holes 210.

[0045] The above embodiments are only used to illustrate the technical solutions of this application and are not intended to limit it. Although this application has been described in detail with reference to the above embodiments, those skilled in the art should understand that modifications or equivalent substitutions to the technical solutions of this application should not depart from the spirit and scope of the technical solutions of this application.
