Description
Technical Field
[0001] This utility model relates to the field of milling cutter technology, specifically to an aluminum alloy high-efficiency heavy-duty roughing milling cutter. Background Technology
[0002] 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. Rough milling cutters for aluminum alloys are key tools for the initial removal of excess material from aluminum alloys. Their selection requires comprehensive consideration of factors such as tool material, cutting edge design, coating technology, and machining parameters. Tungsten carbide tools are the mainstream choice due to their high wear resistance and low chemical affinity with aluminum alloys. Their high strength reduces tool sticking and makes them suitable for high-speed cutting.
[0003] In existing technologies, such as the high-speed precision milling cutter for aluminum alloy disclosed in CN220330071U, a tool holder is included. A fixing rod is fixedly installed at the bottom end of the tool holder, and cutting teeth are respectively provided on the left and right sides of the bottom end of the fixing rod. Grooves are respectively formed on the left and right sides of the outer wall of the tool holder. Adjusting blocks are slidably embedded in the inner cavities of the two grooves. A fixing cavity is formed at the top end of the tool holder, and an adjusting component is provided in the inner cavity of the fixing cavity. The left and right sides of the adjusting component extend into the inner cavities of the two grooves and are respectively fixedly connected to the two adjusting blocks. It can use the adjusting component to drive the adjusting blocks to slide in the inner cavity of the groove to adjust the size of the groove according to the size of the protrusion on the milling machine fixture. This facilitates the installation of the same milling cutter on different milling machine fixtures and solves the problem of the fixed size of the groove at the tool holder of the existing milling cutter, which is not convenient for inserting protrusions of different sizes on different milling machines, resulting in poor flexibility of the milling cutter during use.
[0004] Existing milling cutters can use an adjusting component to drive an adjusting block to slide within the inner cavity of the groove, thereby adjusting the size of the groove according to the size of the protrusion on the milling machine fixture. This makes it convenient to install the same milling cutter on different milling machine fixtures. However, it is inconvenient to protect the milling cutter during use, and it cannot provide protection when the milling cutter is not in use. As a result, when the milling cutter is subjected to external force, the cutting edge is easily damaged, making it impractical. Utility Model Content
[0005] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the present invention.
[0006] Given that the existing technology is inconvenient to protect the milling cutter, and cannot provide protection when the milling cutter is not in use, the cutting edge is easily damaged when the milling cutter is hit by external force, resulting in poor practicality.
[0007] To achieve the above objectives, this utility model provides the following technical solution:
[0008] A high-efficiency heavy-duty roughing milling cutter made of aluminum alloy includes a milling cutter holder. The left side of the milling cutter holder is provided with a protective mechanism for adjusting and protecting the milling cutter. One side of the protective mechanism is provided with a quick-release mechanism for disassembling the milling cutter. The inside of the milling cutter holder is provided with a cooling mechanism for cooling the milling cutter.
[0009] The protective mechanism includes a connector that is telescopically connected to the left side of the milling cutter shank. A milling cutter body is fixed to the left side of the connector. A connecting block that is slidably connected to the milling cutter shank is fixed to the side wall of the connector. Two limiting members are fixed to the outer surface of the connecting block. Each of the two limiting members has a limiting groove slidably connected to the outside of the limiting groove, which is formed on the inner surface of the milling cutter shank.
[0010] As a further improvement of this utility model, the outer wall of the connecting block is connected with a limiting bolt that slides and connects with the milling cutter shank.
[0011] As a further improvement of this utility model, the outer surface of the milling cutter shank is provided with several anti-slip textures at equal intervals.
[0012] As a further embodiment of this utility model: the quick-release mechanism includes a connecting rod, which is fixed to one end of the milling cutter body, and one side of the connecting rod is inserted into a fixing groove opened inside the connector.
[0013] As a further improvement of this utility model: a fixing hole is provided on the outer surface of the connecting rod, and a fixing bolt that is threadedly connected to the connecting piece is inserted into the fixing hole.
[0014] As a further embodiment of this utility model: the cooling mechanism includes a water supply pipe, which is installed inside the milling cutter shank and communicates with the connecting block.
[0015] As a further embodiment of this utility model: one end of the water supply pipe is connected to a fixed shell, the outer wall of the fixed shell is connected to a connecting pipe, and both ends of the fixed shell are inlaid with two fixed bearings sleeved on the water supply pipe.
[0016] As a further improvement of this utility model: the outer surface of the water supply pipe is provided with a through hole, and the side wall of the connecting block is connected to two sets of water spray pipes.
[0017] Compared with the prior art, the beneficial effects of this utility model are:
[0018] 1. This utility model can mill workpieces by setting the milling cutter body. When the milling cutter is not in use, the limiting bolt on the milling cutter holder can be loosened, thereby releasing the fixing of the connecting block.
[0019] 2. This utility model pushes the milling cutter body, causing the connecting block on the connecting piece to move into the inside of the milling cutter holder, thereby retracting the milling cutter body into the milling cutter holder and storing the milling cutter body, which can protect the milling cutter body.
[0020] 3. This utility model removes the fixing bolts on the connector, separating the fixing bolts from the fixing holes on the connecting rod, thus releasing the fixing of the connecting rod. With the cooperation of the fixing groove, the milling cutter body can be disassembled separately.
[0021] 4. This utility model uses a connecting pipe on the fixed shell to connect with an external water supply pipe, allowing external coolant to enter the fixed shell, then flow into the water supply pipe through the through hole, and then be sprayed onto the milling cutter body through the water spray pipe via the connecting block, thereby cooling the milling cutter body and effectively reducing the occurrence of overheating of the milling cutter body.

Detailed Implementation
[0028] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.
[0029] Many specific details are set forth in the following description to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below. Furthermore, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.
[0030] Please see Figures 1-5 This embodiment provides an aluminum alloy high-efficiency heavy-duty roughing milling cutter. The aluminum alloy high-efficiency heavy-duty roughing milling cutter includes a milling cutter holder 1. The left side of the milling cutter holder 1 is provided with a protective mechanism for adjusting and protecting the milling cutter. One side of the protective mechanism is provided with a quick-release mechanism for disassembling the milling cutter. The inside of the milling cutter holder 1 is provided with a cooling mechanism for cooling the milling cutter.
[0031] The protective mechanism includes a connector 2, which is telescopically connected to the left side of the milling cutter holder 1. A milling cutter body 21 is fixed to the left side of the connector 2. A connecting block 22, which is slidably connected to the milling cutter holder 1, is fixed to the side wall of the connector 2. Two limiting members 23 are fixed to the outer surface of the connecting block 22. The two limiting members 23 are slidably connected to limiting grooves 24 opened on the inner surface of the milling cutter holder 1.
[0032] Specifically, the outer wall of the connecting block 22 is connected with a limiting bolt 25 that slides and connects with the milling cutter holder 1.
[0033] Furthermore, by loosening the limiting bolt 25 on the milling cutter holder 1, the fixing of the connecting block 22 is released, which allows the milling cutter body 21 to be pushed.
[0034] Specifically, the outer surface of the milling cutter holder 1 is provided with several anti-slip grooves 3 at equal intervals.
[0035] Furthermore, the anti-slip texture 3 provided on the milling cutter holder 1 can play an anti-slip role, thereby reducing the possibility of displacement of the milling cutter holder 1 during operation.
[0036] In use, the milling cutter holder 1 is connected and fixed to the output end of the machine tool. The anti-slip texture 3 on the milling cutter holder 1 provides anti-slip properties, thereby reducing the possibility of displacement during operation. During use, the milling cutter body 21 can mill the workpiece. When not in use, the limiting bolt 25 on the milling cutter holder 1 can be loosened, thereby releasing the fixing of the connecting block 22. This pushes the milling cutter body 21, causing the connecting block 22 on the connecting piece 2 to move inward into the milling cutter holder 1. The limiting piece 23 and the limiting groove 24 provide guidance, thereby retracting the milling cutter body 21 into the milling cutter holder 1 for safekeeping and protection, effectively reducing the possibility of damage to the milling cutter body 21.
[0037] In summary, this high-efficiency heavy-duty roughing milling cutter made of aluminum alloy can loosen the limiting bolt 25 on the milling cutter holder 1, release the fixing of the connecting block 22, and retract the milling cutter body 21 into the milling cutter holder 1, thereby storing the milling cutter body 21 and protecting it, effectively reducing the possibility of damage to the milling cutter body 21.
[0038] The quick-release mechanism includes a connecting rod 4, which is fixed to one end of the milling cutter body 21. One side of the connecting rod 4 is inserted into a fixing groove 41 opened inside the connector 2. A fixing hole 42 is opened on the outer surface of the connecting rod 4, and a fixing bolt 43 that is threadedly connected to the connector 2 is inserted into the fixing hole 42.
[0039] Furthermore, by unscrewing the fixing bolt 43 on the connector 2, the fixing bolt 43 and the fixing hole 42 on the connecting rod 4 are separated, thus releasing the fixing of the connecting rod 4.
[0040] Specifically, the cooling mechanism includes a water supply pipe 5, which is installed inside the milling cutter shank 1 and is connected to the connecting block 22. One end of the water supply pipe 5 is connected to a fixed shell 51, and the outer wall of the fixed shell 51 is connected to a connecting pipe 52. Both ends of the fixed shell 51 are inlaid with two fixed bearings 53 sleeved on the water supply pipe 5.
[0041] Furthermore, the connecting pipe 52 provided on the fixed housing 51 is connected to the external water supply pipe, so that the external coolant can enter the fixed housing 51.
[0042] Specifically, the outer surface of the water pipe 5 has a through hole 54, and the side wall of the connecting block 22 is connected to two sets of spray pipes 6.
[0043] Furthermore, the coolant is sprayed onto the milling cutter body 21 through the water spray pipe 6 via the connecting block 22, thereby cooling the milling cutter body 21 and effectively reducing the possibility of the milling cutter body 21 overheating.
[0044] In use, by unscrewing the fixing bolt 43 on the connector 2, the fixing bolt 43 and the fixing hole 42 on the connecting rod 4 are separated, and the fixing of the connecting rod 4 is released. With the cooperation of the fixing groove 41, the milling cutter body 21 can be disassembled separately for easy replacement. The connecting pipe 52 provided on the fixed shell 51 is connected to the external water supply pipe, so that the external coolant can enter the fixed shell 51, then flow into the water supply pipe 5 through the through hole 54, and then be sprayed onto the milling cutter body 21 through the water spray pipe 6 via the connecting block 22, thereby cooling the milling cutter body 21 and effectively reducing the possibility of the milling cutter body 21 overheating. In addition, the fixed bearing 53 provided in the fixed shell 51 can ensure that the fixed shell 51 will not rotate when the milling cutter shank 1 rotates, ensuring the normal delivery of coolant.
[0045] In summary, this high-efficiency heavy-duty roughing milling cutter made of aluminum alloy can loosen the limiting bolt 25 on the milling cutter holder 1, release the fixing of the connecting block 22, and retract the milling cutter body 21 into the milling cutter holder 1, thereby storing the milling cutter body 21 and protecting it, effectively reducing the possibility of damage to the milling cutter body 21. Furthermore, by unscrewing the fixing bolt 43 on the connecting piece 2, the fixing bolt 43 and the fixing hole 42 on the connecting rod 4 can be separated. With the cooperation of the fixing groove 41, the milling cutter body 21 can be disassembled separately for easy replacement.
