Description

Technical Field

[0001] This utility model specifically relates to a flexible, multi-support angle milling head. Background Technology

[0002] In the field of machining, angle milling heads are a key machining tool widely used in the machining of various complex parts. They play an irreplaceable role, especially in scenarios that require multi-angle and high-precision machining. They can flexibly change the machining angle of the tool to meet the machining needs of parts of different shapes and sizes, and greatly expand the machining range and capabilities of machining centers and other equipment.

[0003] However, existing angle milling heads generally have a problem that needs to be solved in actual use—angle milling heads are prone to vibration during use.

[0004] From a structural design perspective, most existing angle milling heads adopt relatively simple support structures. The existing supports mainly rely on the mounting cone surface on the tool holder for fixed support. The support method is singular and cannot adjust the support state in real time according to the force conditions during the actual machining process. When machining complex shaped parts, the tool will be subjected to complex cutting forces from different directions. Since the support structure cannot adapt to these force changes, the angle milling head lacks sufficient support stability during the machining process, which in turn causes vibration.

[0005] Vibration of the angle milling head can lead to a series of consequences. First, it has a great impact on machining accuracy. In precision machining, even a small vibration can cause deviations in machining dimensions and increased surface roughness, making the machined parts unable to meet design requirements, resulting in a large number of scraps and rework, and increasing production costs and production cycle.

[0006] Secondly, the vibration of the angle milling head will accelerate the wear of the tool. Under vibration, the contact between the tool and the workpiece is unstable and the cutting force is unevenly distributed. This will cause the cutting edge of the tool to bear greater impact and friction, thereby accelerating the wear rate of the tool and increasing production costs.

[0007] Existing structures include a support structure on the angle milling head, but the structure is relatively simple and cannot adapt to different positional relationships between the angle milling head and the spindle, resulting in poor applicability.

[0008] In summary, existing angle milling heads suffer from vibration issues that severely affect machining accuracy, tool life, and overall equipment performance. Therefore, developing a flexible, multi-support angle milling head that can effectively reduce vibration and improve machining stability is of significant practical importance. Utility Model Content

[0009] The technical problem to be solved by this utility model is that existing angle milling heads, as mentioned in the background art, vibrate during use, which affects the machining accuracy and service life of the angle milling head.

[0010] To address the aforementioned technical problems, a flexible, multi-support angle milling head is proposed. This is achieved through the following technical solution: A flexible, multi-support angle milling head includes a milling head body, which is detachably mounted on the spindle of a machining center via a tool holder. The head body is characterized by further including a clamping ring, a support assembly, and a flexible adjustment assembly. The clamping ring is disposed on the tool holder, one end of the support assembly is movably disposed within the clamping ring, and the flexible adjustment assembly is disposed within the clamping ring. The flexible adjustment assembly controllably adjusts the distance between the support assembly and the spindle end face, supporting the milling head body and the spindle, and ensuring the operational stability of the milling head body.

[0011] In a preferred embodiment of the present invention, the clamping ring includes a tool holder mounting port, a bearing, and a mounting groove. The tool holder mounting port is located in the middle of the clamping ring, and the clamping ring is connected to the tool holder through the tool holder mounting port. The bearing is located inside the tool holder mounting port and connected to the tool holder. The mounting groove is located on the clamping ring, and the cutter head shell at the lower end of the milling head body is connected to the clamping ring through the mounting groove. The clamping ring improves the stability of the support assembly and the flexible adjustment assembly fixed on the milling head body and is convenient to use.

[0012] In a preferred embodiment of the present invention, a support column mounting groove and a locking block mounting groove are also provided on the clamping ring. The support column in the support assembly is set in the support column mounting groove, and the pull-locking block in the flexible adjustment assembly is set in the locking block mounting groove. This arrangement facilitates a stable connection between the clamping ring and the tool holder, thereby improving stability.

[0013] In a preferred embodiment of the present invention, a limiting platform and a mounting block are provided in the mounting groove. The mounting block is placed in the mounting groove and limited by the limiting platform. The cutter head shell at the lower end of the milling head body is connected to the mounting block. The mounting block facilitates a stable connection between the clamping ring and the cutter shank, ensuring the stability of use.

[0014] In a preferred embodiment of the present invention, the support assembly includes a support column, a lifting platform, and a limiting screw. The lifting platform is inserted into the clamping ring and connected to the support column. The limiting screw is set on the clamping ring, and the limiting screw limits the depth to which the lifting platform can be inserted into the clamping ring. This arrangement facilitates the adjustment of the stability of the support as needed.

[0015] In a preferred embodiment of the present invention, the support assembly has multiple sets on the clamping ring. This arrangement improves the stability of the milling head body fixed on the spindle through multi-position support and prevents the milling head body from vibrating.

[0016] In a preferred embodiment of the present invention, the flexible adjustment component includes a spring, a tie-lock block, and an adjusting screw. The spring is disposed within the clamping ring and connected to the support column in the support component. The tie-lock block is disposed within the clamping ring and contacts the lifting platform in the support component. The adjusting screw is connected to the tie-lock block and adjusts the clamping degree of the tie-lock block on the lifting platform. The flexible adjustment component facilitates the adjustment of the height of the support column as needed, adapts to different positional relationships between the angle milling head and the spindle, and has strong applicability.

[0017] In a preferred embodiment of the present invention, the zipper block includes two zipper blocks, each with a clamping groove. The zipper block clamps the lifting platform through the clamping groove. This arrangement facilitates stable clamping of the lifting platform by the zipper block, makes it convenient to restrict the position of the support column, and is easy to use.

[0018] In a preferred embodiment of the present invention, the adjusting screw is a double-ended forward and reverse threaded screw. Rotating the adjusting screw simultaneously adjusts the two pull blocks in the pull lock block to move closer or further apart. This arrangement facilitates the restriction and adjustment of the position of the pull lock block on the support column, making it convenient to use.

[0019] The advantages of this utility model compared with the prior art are: The technical solution of this utility model achieves flexible fit and multiple supports for the milling head body through the combination of clamping ring, support component and flexible adjustment component. The flexible adjustment component can adjust the distance between the support column and the spindle end face according to the actual equipment conditions to ensure that the support column is always in contact with the spindle end face, so that the milling head body can maintain stability under various complex cutting conditions. Effective suppression of milling head vibration improves machining accuracy, reduces machining dimensional deviations and surface roughness issues, and meets the requirements of high-precision machining. At the same time, a stable machining environment reduces tool wear rate, extends tool life, and reduces tool costs and replacement frequency. Attached Figure Description

Detailed Implementation

[0021] The following will refer to the appendix in the embodiments of this utility model. Figure 1-9 The technical solutions in the embodiments of this utility model will be described in detail below. Example

[0022] like Figure 1 , 2 As shown in Figure 9, a flexible fitting multi-support angle milling head includes a milling head body 1, a clamping ring 2, a support assembly 3, and a flexible adjustment assembly 4. The milling head body 1 is mounted on the spindle 5 of a machining center via a tool holder 11. The clamping ring 2 is fixedly mounted on the tool holder 11. The support assembly 3 and the flexible adjustment assembly 4 are installed inside the clamping ring 2. The distance between the support assembly 3 and the spindle end face 51 on the spindle 5 can be adjusted using the flexible adjustment assembly 4.

[0023] Both the milling head body 1 and the spindle 5 are existing devices that can be used directly.

[0024] The main function of the clamping ring 2 is to serve as a carrier for the installation of the support component 3 and the flexible adjustment component 4. The support component 3 and the flexible adjustment component 4 can be installed on the milling head body 1 through the clamping ring 2.

[0025] The main function of the support component 3 is to support the milling head body 1 and the spindle 5, reduce the vibration generated by the tool when the milling head body 1 is in use, improve the machining accuracy, reduce the wear of the tool, increase the service life, and reduce the production cost.

[0026] The main function of the flexible adjustment component 4 is to dynamically adjust the relative position between the support component 3 and the spindle 5, ensuring that the support component 3 always fits the spindle end face 51, and it has strong applicability.

[0027] Definition: In this embodiment, the direction from the milling head body 1 to the spindle 5 is upward, and vice versa.

[0028] like Figure 3 , 4 As shown in Figures 5 and 8, the clamping ring 2 is a metal block with a rectangular cross-section. In order to facilitate fixing the clamping ring 2 to the tool holder 11, a circular opening is provided in the middle of the clamping ring 2. This opening is named the tool holder mounting port 21. The tool holder 11 is inserted into this tool holder mounting port 21.

[0029] To facilitate stable rotation of the milling head body 1 relative to the clamping ring 2 during use and ensure normal operation of the milling head body 1, two bearings 24 are installed inside the tool holder mounting port 21. The outer ring of the bearing 24 is fixed to the inner side wall of the tool holder mounting port 21, and the inner ring of the bearing 24 is fixed to the outer side wall of the tool holder 11. The bearing 24 is fixed in an existing way in this embodiment, such as screw fixing, pin fixing or other existing fixing methods.

[0030] After the handle 11 is connected to the clamping ring 2, in order to facilitate the closure of the handle mounting port 21 above the clamping ring 2, a positioning ring 23 is protruding outward on the upper end face of the clamping ring 2. The positioning ring 23 is set with the handle mounting port 21 at the same center. A cover 29 is placed over the positioning ring 23. The cover 29 is a ring with a "convex" cross-section. The lower end of the cover 29 covers the outside of the positioning ring 23, and the upper end is fixed to the outside of the handle 11 with screws. When the handle 11 rotates, the cover 29 rotates synchronously. The cover 29 can cover the handle mounting port 21 to prevent debris from falling into the handle mounting port 21.

[0031] To facilitate the connection between the clamping ring 2 and the outer shell of the tool mounted at the lower end of the milling head body 1, an annular groove is provided on the lower end face of the clamping ring 2, concentric with the tool holder mounting port 21. This groove is named mounting groove 26. The outer shell of the tool mounted at the lower end of the milling head body 1 is connected to the clamping ring 2 via the mounting groove 26.

[0032] To facilitate the connection between the two, multiple rectangular mounting blocks 28 are placed at intervals in the mounting groove 26. To ensure the stability of the mounting blocks 28 in the mounting groove 26, a rectangular boss protrudes outward on the inner side of the mounting groove 26. This boss is named the limiting platform 27. The limiting platform 27 can stably lock the mounting blocks 28 in the mounting groove 26 and prevent the mounting blocks 28 from falling out of the mounting groove 26.

[0033] A threaded hole is provided on the mounting block 28. The outer shell of the tool is mounted on the lower end of the milling head body 1 and connected to the mounting block 28 with screws to ensure the stability of the connection.

[0034] To facilitate the installation of the mounting block 28 into the mounting slot 26, an installation opening communicating with the mounting slot 26 is provided on the lower end face of the positioning ring 23. The installation opening is rectangular, and the mounting block 28 can be inserted into the mounting slot 26 through the installation opening, making it convenient to use.

[0035] To facilitate the installation of the support column 31 in the support assembly 3, a circular blind hole is provided at each of the four corners of the upper end face of the clamping ring 2. This hole is named the support column mounting groove 22. One end of the support column 31 is inserted into the support column mounting groove 22.

[0036] To facilitate the installation of the flexible adjustment component 4, a groove with an elongated cross-section is provided on the side of the clamping ring 2 near the support column mounting groove 22. This groove is named the lock block mounting groove 25, and the lock block mounting groove 25 is connected to the support column mounting groove 22.

[0037] like Figure 3 , 6 As shown in Figures 8 and 9, the support assembly 3 includes a support column 31, a lifting platform 32, and a limiting screw 33. The support column 31 is connected to the lifting platform 32, and the lifting platform 32 is inserted into the support column mounting groove 22. The limiting screw 33 is screwed onto the upper end face of the clamping ring 2. The limiting screw 33 can limit the insertion depth of the lifting platform 32. (The limiting screw 33 can be selected as needed. In this embodiment, the limiting screw 33 is preferably used to limit the lifting platform 32.)

[0038] The support column 31 and the lifting platform 32 are circular metal rods. The diameter of the lifting platform 32 is larger than that of the support column 31, and the diameter of the lifting platform 32 is the same as that of the support column mounting groove 22. The length of the lifting platform 32 is less than the depth of the support column mounting groove 22, and the lifting platform 32 can be completely inserted into the support column mounting groove 22.

[0039] The limiting screw 33 is an existing screw. The limiting screw 33 is screwed onto the upper surface of the clamping ring 2, close to the support column mounting groove 22. After the limiting screw 33 is screwed on, the lower surface of the nail head on the limiting screw 33 can fit against the upper surface of the lifting platform 32, which facilitates the restriction of the position of the lifting platform 32.

[0040] The support components 3 are provided in four sets, and the four sets of support components 3 are respectively installed on the upper surface of the clamping ring 2.

[0041] like Figure 3 , 4 As shown in 7, 8 and 9, the flexible adjustment component 4 includes a spring 41, a pull lock block 42 and an adjustment screw 44. The spring 41 is placed in the support column mounting groove 22. One end of the spring 41 is in contact with the bottom surface of the support column mounting groove 22, and the other end is in contact with the end face of the lifting platform 32 placed in the support column mounting groove 22.

[0042] The pull lock block 42 includes two locking blocks, each of which is a metal block with an elongated oval cross-section. The cross-sectional dimensions of the locking blocks are the same as those of the locking block mounting groove 25. The pull lock block 42 is placed inside the locking block mounting groove 25. A threaded hole is provided on the pull lock block 42, and an adjusting screw 44 is screwed into this threaded hole. Rotating the adjusting screw 44 can adjust the distance between the two locking blocks in the pull lock block 42, thereby locking the lifting platform 32.

[0043] In order to facilitate the clamping of the lifting platform 32 by the zipper block 42 and to adjust the position of the support column 31, an arc-shaped groove is provided on the side of the zipper block 42 near the support column 31. This groove is named the clamping groove 43. When the two locking blocks of the zipper block 42 are close to each other, the clamping groove 43 can clamp the lifting platform 32.

[0044] To facilitate simultaneous adjustment of the two locking blocks in the pull lock block 42 to move closer or further apart, the adjusting screw 44 is a double-ended screw with opposite threads. The two locking blocks in the pull lock block 42 are screwed onto the two sets of threads respectively. Rotating the adjusting screw 44 allows the two locking blocks in the pull lock block 42 to move closer or further apart simultaneously, thereby clamping the lifting platform 32.

[0045] The usage process of this embodiment is as follows: First, rotate the adjusting screw 44 to loosen the clamping of the pull lock block 42 on the lifting platform 32. Then, rotate the limiting screw 33 to adjust the limitation of the limiting screw 33 on the lifting platform 32. At this time, the support column 31 can rise and fall under the action of the spring 41, which makes it convenient to adjust the position of the support column 31. Then, install the tool holder 11 on the spindle 5, and then adjust the height of the support column 31 until the upper end of the support column 31 is in contact with the end face 51 of the spindle. Then, rotate the adjusting screw 44 to lock the lifting platform 32 using the pull lock block 42. Then, rotate the limiting screw 33 to make the end face of the limiting screw 33 contact the upper end of the lifting platform 32, which makes it convenient to limit the position of the support column 31 and prevent the support column 31 from moving upward.

[0046] The above embodiments are only for illustrating the technical concept of this utility model and should not be construed as limiting the scope of protection of this utility model. Any modifications made to the technical solution based on the technical concept proposed by this utility model shall fall within the scope of protection of this utility model.
