Description

Technical Field

[0001] This utility model relates to the field of machine tool parts technology, specifically to a rotary milling cutter adapter for machining centers. Background Technology

[0002] Cyclone milling is a high-efficiency, high-precision machining method. It utilizes a carbide forming cutter mounted on a high-speed rotating cutter head. While rotating at high speed around its own axis, the cutter also moves helically along the workpiece axis, creating relative motion and thus achieving cutting. When machining rotating surfaces such as threads, the cutting edge of the cutter on the cutter head contacts the workpiece surface, cutting according to a predetermined thread shape to form the desired thread profile.

[0003] A rotary milling cutter head is the supporting structure for the milling cutter. Existing rotary milling cutter heads typically require a dedicated machine tool or tool holder for use. For example, Chinese patent application publication number CN119973709A discloses a rotary milling device for screw machining. This device includes a rotary milling machine tool, a lathe spindle fixedly mounted on the rotary milling machine tool, a fixed base fixedly mounted on the rotary milling machine tool, a milling cutter head movably mounted on the rotary milling machine tool, and a cleaning assembly fixedly mounted on the rotary milling machine tool. The cleaning assembly includes a motor, a first threaded rod fixedly mounted at the motor output end, a gearbox drivingly connected to one side of the first threaded rod, and a second threaded rod drivingly connected to the gearbox. The milling cutter head is movably mounted on the first threaded rod and the second threaded rod. This device completes thread machining by mounting the milling cutter head on a dedicated fixed base and clamping the workpiece to be machined on the lathe spindle. The motor drives the fixed base to move along the extension direction of the workpiece, while the lathe spindle drives the workpiece to rotate.

[0004] In addition, Chinese patent document CN222873978U discloses a cyclone milling power tool holder and a high-efficiency cyclone milling tool. The tool holder includes: a power tool holder; a tool holder connector, which is connected to the machine tool and obtains power; a rotating sleeve, which is assembled on the power tool holder; and a cutter head, which is assembled on the rotating sleeve. A toothed ring is provided on the periphery of the rotating sleeve, and multiple meshing transmission gears are provided in the power tool holder. The tool holder connector drives the rotating sleeve through the transmission gears to realize the rotation of the cutter head.

[0005] However, the above-mentioned equipment still has certain drawbacks in use: the cutter heads of the above-mentioned equipment are all installed on special structures, and the installation interface of the cutter heads is not universal. They need to be adapted to special equipment or machine tools and cannot be installed on CNC machining centers, resulting in poor applicability. When using this cutter head, it is necessary to purchase the corresponding equipment, resulting in high equipment operating costs. In addition, the existing cyclone cutter heads may cause the cutter to overheat due to the inability to discharge chips in time, which may lead to the damage of the cutter. Utility Model Content

[0006] This utility model provides a rotary milling cutter head adapter for machining centers to solve the technical problem of poor applicability of existing internal cyclone cutter heads due to non-universal installation interfaces.

[0007] To solve the above problems, the present invention provides a rotary milling cutter adapter shank for machining centers, which adopts the following technical solution: A rotary milling cutter adapter for a machining center includes an adapter body, one end of which has an adapter section for connecting to a spindle, and the other end has a mounting section, the adapter section having an interface, and the mounting section having a connection port for mounting the cutter head.

[0008] The present invention provides a rotary milling cutter head adapter for machining centers. By setting an adapter interface and a connection port at both ends of the adapter head body, the cutter head can be installed on the adapter head body through the connection port, and then the adapter head body is installed on the spindle through the adapter interface. This realizes the adapter and fixation of the cutter head with various spindles, improves the applicability of the cutter head, and can reduce the supporting cost of the equipment.

[0009] Furthermore, the adapter is an HSK or BT connection.

[0010] Furthermore, the mounting section has a cylindrical structure with a cylindrical cavity inside for inserting the workpiece to be processed, and the side wall of the mounting section has a chip removal hole communicating with the cavity.

[0011] Its beneficial effects are as follows: by setting chip removal holes that connect to the cavity on the side wall of the installation section, the chips generated during the machining process can be discharged in time through the chip removal holes, avoiding the accumulation of chips in the cavity, which would affect the machining accuracy of the workpiece and the service life of the tool, and ensuring the smooth progress of the workpiece machining process.

[0012] Furthermore, there are multiple chip removal holes, each of which is circumferentially distributed on the circumferential surface of the mounting section.

[0013] Furthermore, the chip removal hole is a square hole, and the size of the square hole gradually increases from the inside to the outside in the circumferential direction.

[0014] Furthermore, the edges of each chip removal hole on the outer circumference of the mounting section are chamfered.

[0015] Furthermore, the connection port includes a plurality of threaded holes located on the end face of the mounting section and evenly distributed around the axis of the mounting section, for mounting the cutter head.

[0016] Furthermore, the adapter handle body is made of alloy steel.

[0017] The beneficial effects of the rotary milling cutter adapter shank for machining centers provided by this utility model are: 1. The rotary milling cutter head adapter provided by this utility model has an adapter interface and a connection port respectively set at both ends of the adapter head body, so that the cutter head can be installed on the adapter head body through the connection port, and then the adapter head body is installed on the spindle through the adapter interface. This realizes the adapter and fixation of the cutter head with various spindles, improves the applicability of the cutter head, and can reduce the supporting cost of the equipment.

[0018] 2. HSK and BT connections are the standard interface forms for connecting machine tool spindles and cutting tools. The use of HSK and BT connections gives this adapter good versatility and compatibility, making it easy to connect this adapter to various machining center spindles that use the same interface, thus expanding the applicability of the adapter.

[0019] 3. By setting chip removal holes that connect to the cavity on the side wall of the installation section, the chips generated during the machining process can be discharged in a timely manner through the chip removal holes, avoiding the accumulation of chips in the cavity, which would affect the machining accuracy of the workpiece and the service life of the tool, and ensuring the smooth progress of the workpiece machining process.

[0020] 4. By evenly distributing the chip removal holes around the circumference of the mounting section, the chip removal effect of the adapter handle body can be enhanced. Chips generated in all directions can be discharged in time through the nearby chip removal holes, reducing the possibility of local chip accumulation and further improving the chip removal effect.

[0021] 5. The design of the chip removal hole gradually increasing in size from the inside to the outside helps the chips to be discharged more smoothly. When the chips move from the inside to the outside in the installation section, the gradually enlarging hole diameter can reduce the friction and blockage between the chips and the hole wall, thereby improving the chip removal efficiency.

[0022] 6. The chamfered design prevents sharp edges of the chip discharge hole from injuring operators, improving the safety of the adapter handle. In addition, the chamfer reduces stress concentration, strengthens the edge structure of the chip discharge hole, and extends the service life of the adapter handle. Attached Figure Description

[0025] The principles and spirit of this utility model will be explained in detail below with reference to several representative embodiments.

[0026] Embodiment 1 of the rotary milling cutter adapter shank for machining centers provided by this utility model: like Figures 1 to 2 As shown, a rotary milling cutter adapter for a machining center includes an adapter body 1, which is a one-piece structure made of alloy steel. The adapter body 1 includes an adapter section 2 at one end and a mounting section 3 at the other end. The adapter section 2 is used to fix the spindle, and the mounting section 3 is used to mount the cutter head.

[0027] The adapter section 2 includes an adapter interface 21. In this embodiment, the adapter interface 21 is an HSK connection, which has strong versatility and compatibility. It can easily connect the adapter handle to various machining center spindles that use the same interface, thus expanding the applicability of the adapter handle.

[0028] The mounting section 3 is a cylindrical structure with a coaxial cylindrical cavity inside. The cavity communicates with the outside through the end of the mounting section 3 for inserting the workpiece to be processed. The adapter handle body 1 has a chip removal hole 32 on the side wall of the mounting section 3 that communicates with the cavity, so that the chips generated during processing can be discharged in time through the chip removal hole 32, avoiding the accumulation of chips in the cavity, which would affect the machining accuracy of the workpiece and the service life of the tool, and ensuring the smooth progress of the workpiece processing.

[0029] To enhance the chip removal effect of the adapter handle body 1, the mounting section 3 has two sets of chip removal holes 32 along the axial direction. Each set includes four chip removal holes 32 evenly distributed around the axis of the mounting section 3. This allows chips generated in all directions to be discharged promptly through the nearby chip removal holes 32, reducing the possibility of local chip accumulation and further improving the chip removal effect during adapter handle use. Furthermore, each of the chip removal holes 32 is square in shape. The square shape of the chip removal holes 32 can improve the chip removal effect of the adapter handle body 1 while ensuring structural strength, reducing the probability of chip clogging.

[0030] Furthermore, the chip removal hole 32 gradually increases in size from the inside to the outside in the circumferential direction, making its cross-section perpendicular to the axial direction fan-shaped. This design helps the chips to be discharged more smoothly. When the chips move from the inside to the outside within the mounting section 3, the gradually enlarging hole diameter can reduce the friction and clogging between the chips and the hole wall, thereby improving the chip removal efficiency.

[0031] The connection port 31 of the mounting section 3 is located on its end face. The connection port 31 includes multiple threaded holes 33 evenly distributed around the axis in the circumferential direction. The threaded holes 33 are used to mount the cutter head. The evenly distributed threaded holes 33 ensure that the installation of the cutter head on the end face of the mounting section 3 has good symmetry and balance, so that the cutter head is subjected to uniform force during rotation, thereby improving the machining accuracy and stability. The threaded connection method makes it convenient to install and remove the cutter head, and facilitates the replacement of different types of cutter heads to meet different machining needs.

[0032] The working principle of a rotary milling cutter adapter shank for machining centers is summarized as follows: By providing adapter interfaces 21 and connection ports 31 at both ends of the adapter shank body 1, the tool head can be mounted on the adapter shank body 1 via the connection port 31. The adapter shank body 1 is then mounted on the spindle via the adapter interface 21, achieving a seamless connection and fixation between the tool head and the spindle. This improves the tool head's applicability and reduces equipment costs. Furthermore, by providing multiple square chip removal holes 32 in the mounting section 3 of the adapter shank body 1, smooth chip removal during workpiece machining is ensured, which helps extend the tool's lifespan.

[0033] Embodiment 2 of the rotary milling cutter adapter shank for machining centers provided by this utility model: Its main difference from Example 1 is: In Example 1, the adapter uses an HSK connection method.

[0034] In this embodiment, the adapter is a BT, BBT, or CAPTO connection.

[0035] Embodiment 3 of the present invention provides a rotary milling cutter adapter for machining centers: Its main difference from Example 1 is: In Example 1, the adapter handle body has eight chip removal holes, which are square in shape.

[0036] In this embodiment, the shape of the chip removal holes is circular or other shapes, and the number can be adjusted according to the shape and size of the chip removal holes, without limitation.

[0037] Based on the above description in this specification, those skilled in the art will also understand that the following terms, such as "upper," "lower," "front," "rear," "left," "right," "width," "horizontal," "top," "bottom," "inner," and "outer," which indicate orientation or positional relationships, are based on the orientation or positional relationships shown in the accompanying drawings of this specification. They are only for the purpose of facilitating the explanation of the present invention and simplifying the description, and do not explicitly or implicitly suggest that the device or element involved must have the specific orientation, or be constructed and operated in a specific orientation. Therefore, the above-mentioned orientation or positional relationship terms should not be understood or interpreted as limitations on the present invention.

[0038] In addition, in the description of this specification, "multiple" means at least two, such as two, three or more, etc., unless otherwise expressly and specifically defined.
