Description

Technical Field

[0001] This utility model relates to the field of milling cutter technology, and in particular to a milling cutter with a chamfering function. Background Technology

[0002] Currently, chamfering end mills are end mills specifically designed for chamfering operations. Their cutting edge shape and angle are specially designed, and common types include single-angle chamfering end mills and double-angle chamfering end mills. Single-angle chamfering end mills are typically used to process chamfers at a single angle, such as the common 45° chamfer; double-angle chamfering end mills can process two chamfers at two different angles simultaneously, suitable for some special chamfering requirements. When chamfering parts, it is necessary to change the chamfering end mill according to the different chamfer angles.

[0003] However, most existing chamfering end mills are one-piece structures. When replacing one-piece chamfering end mills, the entire machine needs to be disassembled. Special tools are needed to loosen the fixing screws or clamps. The operation steps are numerous and time-consuming. When machining parts with chamfering at multiple angles, the machine needs to be stopped, the old end mill removed, the new end mill installed, and the tool re-set every time the chamfering angle is changed, resulting in a significant reduction in machining efficiency. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a milling cutter with chamfering function.

[0005] This utility model is achieved by the following technical solution: a milling cutter with chamfering function, including a cutter shank, one end of which is provided with a chamfering milling cutter head for chamfering, one side of which is provided with a connecting component connected to the cutter shank, and both sides of the cutter shank are provided with fixing components for fixing the connecting component, the connecting component including a connecting post fixedly installed on one side of the chamfering milling cutter head, one end of the cutter shank having a connecting groove, and one end of the connecting post extending into the interior of the connecting groove.

[0006] Through the above technical solution, the chamfering end mill head forms a detachable connection structure by cooperating with the connecting groove of the connecting post and the tool holder, laying the foundation for quick replacement of the chamfering end mill head.

[0007] As a further improvement to the above solution, fixing slots are provided on both sides of the connecting column, and fixing blocks are provided on both sides of the tool bar. One side of each of the two fixing blocks penetrates the tool bar and extends into the interior of the adjacent fixing slot.

[0008] Through the above technical solution, the fixing block is inserted into the fixing groove to fix the connecting column, thereby ensuring the stability of the connection between the chamfering milling cutter head and the tool holder, and ensuring the reliable operation of the tool during the machining process.

[0009] As a further improvement to the above solution, a movable ring is slidably sleeved on the tool holder, and the fixing assembly includes a first push plate rotatably mounted on one side of the bottom end of the movable ring, a second push plate rotatably mounted on one end of the first push plate, and one side of the second push plate is fixedly mounted to one side of an adjacent fixing block.

[0010] Through the above technical solution, the up and down sliding of the moving ring is driven by the first push plate and the second push plate to realize the movement of the fixed block, thereby controlling the fixing and disassembly of the connecting column, forming a linkage fixing mechanism that is easy to operate.

[0011] As a further improvement to the above solution, limiting plates are provided on both sides of the two second push plates. One end of each limiting plate passes through the knife bar and the adjacent fixing block. The end of each limiting plate that passes through the knife bar extends to one side of the inner cavity of the connecting groove. A sliding groove is provided on one side of each limiting plate. A sliding plate is slidably arranged inside each sliding groove. One side of each sliding plate is fixedly installed with the adjacent second push plate.

[0012] Through the above technical solution, the setting of the limiting plate and the sliding plate plays a limiting and guiding role in the movement of the second push plate, ensuring the accurate movement trajectory of the fixed block, avoiding deviation or jamming, and improving the stability and reliability of the mechanism.

[0013] As a further improvement to the above solution, a first connecting plate is fixedly installed at the bottom of each of the two second push plates, an elastic band is fixedly installed on one side of each of the two first connecting plates, a second connecting plate is fixedly installed at one end of each of the two elastic bands, and one side of each of the two second connecting plates is fixedly installed with the tool bar.

[0014] Through the above technical solution, the elastic band provides a reset pull force, which assists the second push plate and the fixing block in resetting when replacing the chamfering milling cutter head, reducing the labor intensity of the operator, while ensuring that the fixing block can be quickly and accurately inserted into the fixing groove, thus improving the replacement efficiency.

[0015] As a further improvement to the above solution, a threaded post is provided on one side of the moving ring, one end of the threaded post is threaded through the moving ring and abuts against the tool bar, and a rotating block is fixedly installed on the other end of the threaded post.

[0016] With the above technical solution, the threaded column is used to fix the position of the moving ring. When the moving ring slides to the designated position, the threaded column is rotated to make it press against the tool holder, preventing the moving ring from sliding during the processing and ensuring the stability of the fixing component.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0018] This invention achieves rapid replacement of chamfering milling cutter heads with different angles through the design of a detachable connection and fixing assembly between the chamfering milling cutter head and the cutter shank. It eliminates the need for complete tool disassembly; replacement can be completed simply by moving the ring and threaded post, significantly reducing downtime and improving processing efficiency. Simultaneously, it avoids the tool setting accuracy deviation and tool wear problems caused by frequent replacement of integrated milling cutters, ensuring processing accuracy and tool life. It is suitable for machining parts with chamfered angles in various scenarios. Attached Figure Description

[0028] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0029] Please combine Figures 1-7This embodiment of a milling cutter with chamfering function includes a cutter bar 1, one end of which is provided with a chamfering milling cutter head 2 for chamfering, one side of the chamfering milling cutter head 2 is provided with a connecting component that connects to the cutter bar 1, and both sides of the cutter bar 1 are provided with fixing components for fixing the connecting component.

[0030] The connecting assembly includes a connecting post 301 fixedly installed on one side of the chamfering milling cutter head 2, a connecting groove 302 is provided at one end of the cutter bar 1, one end of the connecting post 301 extends into the interior of the connecting groove 302, a fixing groove 5 is provided on both sides of the connecting post 301, a fixing block 6 is provided on both sides of the cutter bar 1, and one side of each fixing block 6 penetrates the cutter bar 1 and extends into the interior of the adjacent fixing groove 5.

[0031] The chamfering milling cutter head 2 is connected to the connecting groove 302 of the tool holder 1 through the connecting post 301 to form a detachable connection structure. The fixing block 6 is inserted into the fixing groove 5 to fix the connecting post 301, thereby ensuring the stability of the connection between the chamfering milling cutter head 2 and the tool holder 1 and ensuring the reliable operation of the tool during the machining process.

[0032] A movable ring 7 is slidably sleeved on the tool holder 1. The fixing assembly includes a first push plate 401 rotatably mounted on one side of the bottom end of the movable ring 7. A second push plate 402 is rotatably mounted on one end of the first push plate 401. One side of the second push plate 402 is fixedly mounted to one side of the adjacent fixing block 6.

[0033] The up-and-down sliding of the moving ring 7 is driven by the first push plate 401 and the second push plate 402, thereby moving the fixed block 6, controlling the fixing and disassembly of the connecting column 301, forming a linkage fixing mechanism that is easy to operate.

[0034] Both sides of the two second push plates 402 are provided with limiting plates 8. One end of each limiting plate 8 passes through the knife bar 1 and the adjacent fixing block 6. The end of each limiting plate 8 that passes through the knife bar 1 extends to one side of the inner cavity of the connecting groove 302. A sliding groove is opened on one side of each limiting plate 8. A sliding plate 9 is slidably arranged inside each sliding groove. One side of each sliding plate 9 is fixedly installed with the adjacent second push plate 402.

[0035] The limiting plate 8 and the sliding plate 9 limit and guide the movement of the second push plate 402, ensuring the accurate movement trajectory of the fixed block 6, avoiding deviation or jamming, and improving the stability and reliability of the mechanism.

[0036] A first connecting plate 10 is fixedly installed on the bottom of each of the two second push plates 402. An elastic band 11 is fixedly installed on one side of each of the two first connecting plates 10. A second connecting plate 12 is fixedly installed on one end of each of the two elastic bands 11. One side of each of the two second connecting plates 12 is fixedly installed with the tool bar 1.

[0037] The elastic band 11 provides a reset pull force, which assists the second push plate 402 and the fixing block 6 in resetting when replacing the chamfering milling cutter head 2, reducing the labor intensity of the operator, and ensuring that the fixing block 6 can be quickly and accurately inserted into the fixing groove 5, thereby improving the replacement efficiency.

[0038] A threaded post 13 is provided on one side of the moving ring 7. One end of the threaded post 13 is threaded through the moving ring 7 and abuts against the tool holder 1. A rotating block is fixedly installed on the other end of the threaded post 13.

[0039] The threaded post 13 is used to fix the position of the moving ring 7. When the moving ring 7 slides to the specified position, the threaded post 13 is rotated to make it abut against the tool holder 1 to prevent the moving ring 7 from sliding during the machining process and to ensure the stability of the fixed component.

[0040] The implementation principle of a milling cutter with chamfering function in this application embodiment is as follows: when replacing the chamfering milling cutter head 2, first rotate the threaded column 13 to separate it from the cutter bar 1, thereby releasing the fixing effect on the moving ring 7.

[0041] As the moving ring 7 slides downward, the first push plate 401 at the bottom of the moving ring 7 also descends. Since the first push plate 401 is rotatably connected to the moving ring 7 and is at an inclined angle, the first push plate 401 pushes the second push plate 402 to move outward when it descends.

[0042] The second push plate 402, guided by the limiting plate 8 and the sliding plate 9, drives the fixing block 6 to be pulled out from the fixing groove 5 of the connecting column 301, so that the connecting column 301 is separated from the tool holder 1, and the old chamfering milling cutter head 2 can be removed.

[0043] When installing a new chamfering end mill 2, insert the connecting post 301 of the new chamfering end mill 2 into the connecting groove 302 of the tool holder 1, so that the fixing groove 5 is aligned with the position of the fixing block 6.

[0044] Pull the moving ring 7 upwards, and the moving ring 7 will drive the first push plate 401 to rise. At the same time, the elastic band 11 will pull the second push plate 402 to move inwards through the first connecting plate 10.

[0045] During the upward movement of the first push plate 401, the tilt angle pulls the second push plate 402 inward. The two work together to insert the fixing block 6 into the fixing groove 5, thereby fixing the connecting column 301.

[0046] Finally, rotate the threaded column 13 to make it press against the tool holder 1, fix the position of the moving ring 7, and ensure that the fixed component is stable and reliable during the machining process.

[0047] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
