Description

Technical Field

[0001] This utility model relates to the field of milling cutter equipment technology, specifically a burr-free milling cutter for processing aerospace materials. 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. Milling cutters are mainly used on milling machines to machine planes, steps, grooves, shaped surfaces, and cut off workpieces. The cutting inserts of the milling cutter are another important factor. Having more than one cutting insert participating in cutting simultaneously during any single milling operation is advantageous, but having too many cutting inserts simultaneously is a disadvantage. During cutting, each cutting edge cannot cut simultaneously; the required power is related to the number of cutting edges participating in the cutting. The position of the milling cutter relative to the workpiece plays a crucial role in the chip formation process, cutting edge load, and machining results. In face milling, using a milling cutter with a width approximately 30% larger than the cutting width and positioning the cutter close to the center of the workpiece results in minimal variation in chip thickness. The chip thickness at the entry and exit points is slightly thinner than the chip thickness when cutting at the center.

[0003] A publicly available patent (publication number CN221110030U) discloses a burr-free T-slot milling cutter, belonging to the category of non-ferrous metal machining tools. The cutter shank and cutting part are formed by a single machining process using cemented carbide. The shank and handle are welded together, with a 60-degree angle at the connection between the shank and handle. The cutting part has four cutting edges, with the rake face of each edge making a 15-degree angle with the axis. The connection between the cutting edges and the shank has a 0.3mm radius. Its advantages include a novel structure. When machining internal grooves in parts, the highly optimized cutting angle allows for quick and convenient machining of T-slots using three-axis CNC milling machines, four-axis CNC machine tools, and even multi-axis machining centers. This not only ensures precision but also eliminates burrs even when the machined part's edge is magnified 30 times, reducing the time and cost associated with burr removal processes. This not only guarantees product quality but also significantly reduces processing costs, aligning with the lean manufacturing principles of enterprises.

[0004] However, there are some problems in the use of existing burr-free end mills: 1. The burr removal process of burr-free end mills on the market is not convenient enough, which makes it easy for burrs to increase, resulting in quality problems in the processing of aerospace materials and causing unnecessary economic losses; 2. The burr removal process of burr-free end mills on the market lacks an automated grinding device, which reduces the overall grinding efficiency and lowers the overall production efficiency. Utility Model Content

[0005] The purpose of this invention is to provide a burr-free end mill for machining aerospace materials, in order to solve the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a burr-free end mill for processing aerospace materials, comprising a cutter post, a grinding guide assembly disposed on the surface of the cutter post, and an automatic deburring assembly disposed on the surface of the cutter post;

[0007] A blade is fixedly connected to the surface of the blade column;

[0008] The grinding guide assembly includes a grinding sleeve movably connected to the surface of the blade. The grinding sleeve has a grinding port inside, and a grinding plate is fixedly connected inside the grinding port. A handle is fixedly connected to the surface of the grinding sleeve. The blade is ground through the grinding sleeve.

[0009] The automatic deburring assembly includes telescopic rods disposed on both sides of the blade column surface. A connecting block is detachably connected to one end of the telescopic rod. A first connecting hole is opened on the surface of the connecting block. A horizontal plate is connected to one end of the connecting block. The telescopic rod drives the abrasive sleeve to move.

[0010] As a further improvement of this utility model, the grinding guide assembly also includes uprights disposed on both sides of the blade post surface, and one end of the uprights is provided with an insertion port.

[0011] As a further improvement of this utility model: a plug is movably connected inside the socket, and a second screw hole is provided at the bottom of the plug.

[0012] As a further embodiment of this utility model: a first screw hole is provided at the top of the upright, the inside of the first screw hole communicates with the inside of the socket, the inside of the first screw hole and the second screw hole are aligned, and a bolt is fitted inside the first screw hole and the second screw hole.

[0013] As a further improvement of this utility model, the automatic deburring assembly also includes a connection port opened at one end of the horizontal plate, and a second connection hole is opened on the surface of the horizontal plate, the interior of the second connection hole communicating with the interior of the connection port.

[0014] As a further embodiment of this utility model: a base is connected to the bottom of the blade column, horizontal blocks are fixedly connected to both sides of the surface of the base, a mounting seat is detachably connected to the surface of the horizontal blocks, a mounting plate is connected to the surface of the mounting seat, and a telescopic rod is detachably connected to the surface of the mounting plate.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] In use, the user places a grinding sleeve over the blade surface. The grinding sleeve fits against the blade surface through an internal grinding port. A detachably connected grinding plate inside the grinding port contacts the blade surface. The user can then move the grinding sleeve back and forth across the blade surface using a handle fixedly connected to the grinding sleeve. This effectively removes burrs from the blade surface through the grinding plate. During grinding, a movable insert is connected inside the handle. The bottom of the insert connects to a vertical rod, which connects to the insert through an internal slot. After the insert is inserted into the slot, the second screw hole on the insert surface aligns with the first screw hole on the bottom of the insert. A bolt is then tightened to secure the insert to the vertical rod. The insert provides guidance for the grinding sleeve, making the burr-free end mill's overall burr removal process more convenient and reducing the likelihood of increased burrs. This reduces the risk of quality issues in processing aerospace materials and minimizes unnecessary economic losses.

[0017] In the grinding process of this invention, a horizontal plate fixedly connected to one end of the handle is connected to a connecting block through an internal connecting port. When the connecting block is inserted into the connecting port, the first connecting hole on the surface of the connecting block aligns with the second connecting hole on the surface of the horizontal plate. A bolt is then tightened to fix the entire assembly. The telescopic rod is connected to a base that mates with the bottom of the cutter post via a detachable mounting plate, thus facilitating the installation of the telescopic rod. When the power input terminal of the telescopic rod is connected to an external power source, the telescopic rod is energized and operates, causing the connecting block at one end to move up and down. This, in turn, causes the horizontal plate to move, which in turn causes the handle and the grinding sleeve to move up and down, thus automatically grinding the cutting tool. Consequently, the burr-free milling cutter has an automated grinding device during the burr grinding process, thereby improving the overall grinding efficiency and increasing the overall production efficiency.

The horizontal blocks 3 connect to the mounting seat 501, enabling the telescopic rod 503 to be connected to the mounting seat 501 via the mounting plate 502 connected to the bottom.

[0028] Working principle: During use, the user places a grinding sleeve 401 on the surface of the blade 2. The grinding sleeve 401 fits against the surface of the blade 2 through an internal grinding port 402. A grinding plate, detachably connected inside the grinding port 402, contacts the surface of the blade 2. The user can then move the grinding sleeve 401 back and forth on the surface of the blade 2 using a handle 403 fixedly connected to its surface. This effectively polishes the burrs on the surface of the blade 2 through the grinding plate. During the polishing process, the handle 403... The unit is connected to a plug 407, the bottom of which is connected to a vertical pole 404. The vertical pole 404 is connected to the plug 407 through an internal socket 405. After the plug 407 is inserted into the socket 405, the second screw hole 408 on the surface of the plug 407 is aligned with the first screw hole 406 on the bottom of the plug 407, and the bolt 409 is tightened to fix the plug 407 and the vertical pole 404. The horizontal block 3 is installed through the base 6, and the mounting base 501 is connected through the horizontal block 3. The telescopic rod 503 is connected to the mounting base 501 via the mounting plate 502 that fits at the bottom. The insert post 407 provides guidance for the frosted sleeve 401. A horizontal plate 506, fixedly connected to one end of the handle 403, is connected to the connecting block 504 via an internal connecting port 508. When the connecting block 504 is inserted into the connecting port 508, the first connecting hole 505 on the surface of the connecting block 504 aligns internally with the second connecting hole 507 on the surface of the horizontal plate 506, and the bolt 409 is then tightened to secure the entire assembly. The telescopic rod 503 is fixed and connected to the base 6 at the bottom of the blade column 1 via a mounting plate 502 that is detachably connected to the bottom, thus increasing the installation of the telescopic rod 503. At this time, the power input terminal of the telescopic rod 503 is connected to an external power source, and the telescopic rod 503 is powered on and works, driving the connecting block 504 connected at one end to move up and down. In turn, the connecting block 504 drives the horizontal plate 506 to move. When the horizontal plate 506 moves, it drives the handle 403 and the grinding sleeve 401 to move up and down, thereby automatically grinding the blade 2.
