Description

Technical Field

[0001] This utility model relates to the field of machining technology, and in particular to a milling cutter with multi-surface machining. Background Technology

[0002] Currently, a milling cutter is a rotating cutting tool with one or more cutting teeth used for milling operations. During operation, each cutting tooth sequentially and intermittently removes the excess material from the workpiece. Milling cutters are mainly used on milling machines to machine planes, steps, grooves, shaped surfaces, and to cut off workpieces. Changing tools for milling multiple surfaces usually requires changing different types of tools, which is time-consuming and cumbersome.

[0003] Chinese patent CN215392714U discloses a nickel-based alloy milling cutter capable of simultaneously machining multiple surfaces. The first milling cutter post is a frustum-shaped structure with milling teeth on its sidewalls, the second milling cutter post is a columnar structure, and the sidewalls of the milling cutter disc are also toothed. The diameter of the milling cutter disc is larger than that of the first and second milling cutter posts. Through these three different milling structures, the milling cutter device can simultaneously mill multiple surfaces of a workpiece. However, in practice, when using other milling cutters, the vertical position of the bottommost milling cutter is difficult to adjust, easily causing interference with other workpieces, thus failing to meet the needs of different scenarios.

[0004] To address the aforementioned technical shortcomings, a solution is proposed. Utility Model Content

[0005] The purpose of this invention is to provide a milling cutter with multi-surface machining capabilities to solve the problems mentioned in the background art.

[0006] The purpose of this utility model can be achieved through the following technical solution: a milling cutter with multi-surface processing, including a cutter post, a connector fixedly connected to the bottom end of the cutter post, a plug rod fixedly connected to the top end of the cutter post, a cutting blade penetrating and fixedly connected to the connector, a cutter holder penetrating and fixedly connected to the bottom end of the connector, a communicating cavity opened in the center of the connector and the cutter post, and an adjustment structure provided in the cavity of the cutter post and the connector;

[0007] The adjustment mechanism includes a blade rod that is screwed to the blade post and the connector cavity. A connector rod is fixedly connected to the top of the blade rod. A rotating column is slidably connected through the connector rod and vertically through the rotating column. An adjustment block is slidably connected through the rotating column and vertically through the rotating column.

[0008] Preferably, the outer wall of the blade holder has a ring array of multiple connecting seats, and the surface of the connecting seats is fixedly mounted with a second blade.

[0009] Preferably, a connecting ring is fixedly connected to the lower surface of the tool holder, and a fixing rod that passes through the connecting ring and the tool holder is fixedly connected to the lower surface of the connecting ring.

[0010] Preferably, the insert rod is fixedly connected to the outer wall near the top, the upper surface of the adjusting block is provided with a ring array of positioning grooves, and the top of the blade post is provided with an insertion groove that matches the positioning grooves.

[0011] Preferably, a limiting groove is formed on the outer wall of the rotating column, and a positioning piece is fixedly connected to the inner wall of the limiting groove, with the lower surface of the positioning piece abutting against the upper surface of the adjusting block.

[0012] The beneficial effects of this utility model are:

[0013] (1) This utility model adjusts the height of the cutter in the vertical direction by setting the cutter bar to rotate while moving in the vertical direction, thereby enhancing the variability of the milling cutter structure. It can be adjusted according to different processing needs. Because it has the height adjustment function, it can better adapt to different processing scenarios. Different processing tasks may have different requirements for the extension length and working position of the milling cutter. It can switch between blade one, blade two and cutter bar to meet diverse needs.

[0014] (2) By using the positioning plate to abut against the upper surface of the adjusting block and the screw to pass through the positioning hole for fixed connection, the position of the adjusting block in the vertical direction can be accurately positioned, which can ensure the stability of the height of the tool bar after adjustment and avoid the tool bar's accurate position being affected by the loosening or displacement of the adjusting block during the processing, thereby ensuring the processing accuracy.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Example 1:

[0023] Please see Figures 1-4 As shown, this embodiment is a milling cutter with multi-surface machining, including a cutter post 1. A connector 3 is fixedly connected to the bottom end of the cutter post 1, and a plug rod 2 is fixedly connected to the top end of the cutter post 1. A cutting insert 6 is passed through and fixedly connected to the connector 3, and a cutter holder 7 is passed through and fixedly connected to the bottom end of the connector 3. A communicating cavity is formed between the connector 3 and the center of the cutter post 1. An adjustment structure is provided in the cavity of the cutter post 1 and the connector 3. The adjustment mechanism includes a cutter bar 12 screwed to the cavity of the cutter post 1 and the connector 3. A plug rod 13 is fixedly connected to the top end of the cutter bar 12. A rotating column 5 is passed through and vertically slidably connected to the plug rod 13. An adjusting block 4 is passed through and vertically slidably connected to the rotating column 5. By rotating the adjusting block 4, the position of the plug rod 13 is adjusted. Under the action of the adjustment block 4, the tool holder 12 can move and rotate in the vertical direction, adjusting the height of the tool holder 12 in the vertical direction, making it easier to store the tool holder 12 inside the tool post 1, meeting the needs of different scenarios, and enabling the tool holder 7 to be used better. Rotating the adjustment block 4, under the action of the plug rod 13, the tool holder 12 can move and rotate in the vertical direction, thereby adjusting the height of the tool holder 12 in the vertical direction, enhancing the variability of the milling cutter structure, and can be adjusted according to different processing needs. Due to its height adjustable function, it can better adapt to different processing scenarios. Different processing tasks may have different requirements for the extension length, working position, etc. of the milling cutter, which can meet these diverse needs.

[0024] The outer wall of the tool holder 7 has a ring array of multiple connecting seats 8. The surface of the connecting seat 8 is fixedly mounted with a second blade 9, which can be replaced to further meet different needs.

[0025] A connecting ring 10 is fixedly connected to the lower surface of the tool holder 7. A fixing rod 11 is fixedly connected to the lower surface of the connecting ring 10, passing through the connecting ring 10 and the tool holder 7. The connecting ring 10 and the fixing rod 11 enable the tool holder 7 to be stably connected to the end of the connector 3, and also enable the tool holder 7 to be disassembled.

[0026] The insertion rod 2 is fixedly connected to the outer wall near the top. The upper surface of the adjusting block 4 is provided with a ring array of positioning grooves. The top of the blade post 1 is provided with an insertion groove that matches the positioning groove. By positioning the adjusting block 4, the rotation of the adjusting block 4 can be prevented, thereby positioning the vertical position of the blade post 12.

[0027] Example 2:

[0028] Please see Figures 1-4 As shown in the figure, in this embodiment, a milling cutter with multi-surface machining has a limiting groove 14 on the outer wall of the rotating column 5. A positioning piece 15 is fixedly connected to the inner wall of the limiting groove 14. The lower surface of the positioning piece 15 abuts against the upper surface of the adjusting block 4. Both the positioning piece 15 and the limiting groove 14 have positioning holes. The positioning piece 15 is fixedly connected to the rotating column 5 by screws, thereby achieving the positioning of the vertical position of the adjusting block 4.

[0029] Combining Embodiment 1 and Embodiment 2, by setting the tool holder 12 to rotate while moving vertically, the height of the tool holder 12 in the vertical direction can be adjusted, thereby enhancing the variability of the milling cutter structure. It can be adjusted according to different processing requirements. Due to its height adjustable function, it can better adapt to different processing scenarios. Different processing tasks may have different requirements for the extension length, working position, etc. of the milling cutter. It can switch between insert 6, insert 9 and tool holder 12 to meet diverse needs.

[0030] By using the positioning piece 15 to abut against the upper surface of the adjusting block 4 and the screw to pass through the positioning hole for fixed connection, the position of the adjusting block 4 in the vertical direction can be accurately positioned. This ensures that the height of the tool holder 12 is stable after adjustment, and avoids affecting the accurate position of the tool holder 12 due to the loosening or displacement of the adjusting block 4 during the machining process, thereby ensuring machining accuracy.
