Abstract
Description
Technical Field
[0001] This utility model relates to the field of milling cutter technology, specifically a stepped variable diameter high-temperature alloy deep groove milling cutter. Background Technology
[0002] The stepped-diameter high-temperature alloy deep groove end mill is a special end mill used for machining deep groove structures in high-temperature alloy materials. The tool diameter changes in a stepped manner along the axial direction, and layered cutting is achieved through cutting edges of different diameters, reducing the depth of cut per pass, cutting force and vibration. It is suitable for solving problems such as chip removal difficulties and insufficient tool rigidity caused by groove depth in deep groove machining. The tool body is made of high-hardness, high-red-hardness cemented carbide or cermet, such as cobalt and tantalum ultrafine-grained cemented carbide, to withstand the high temperature and severe friction in high-temperature alloy machining.
[0003] In existing technologies, such as the Christmas tree step milling cutter disclosed in CN212329789U, a cross-shaped cutting edge is provided. This cutting edge is arranged in multiple stepped layers from front to back, with the circumference diameter of each layer being larger than that of the layer above. A heat dissipation device is fixedly connected to the lower end face of the cutter head, and a shank is fixedly connected to the lower end of the heat dissipation device. The axes of the cutter head, heat dissipation device, and shank are coincident, and the center of the front end of the cutter head is threadedly connected to an anti-collision device. It utilizes multiple heat dissipation holes to allow the heat dissipation device to quickly dissipate heat, thereby cooling the cutter head. The other end of the through-holes in the cutter head is frustum-shaped, which increases the contact area between the graphene and the heat dissipation device, allowing for better heat transfer and dissipation.
[0004] Existing milling cutters use multiple heat dissipation holes to quickly dissipate heat from the cutting head. However, because the milling cutter rotates at high speed during operation and cuts by friction between the cutter and the workpiece, relying solely on heat dissipation holes to dissipate heat from the cutter is ineffective. As a result, the temperature of the milling cutter cannot be effectively reduced, which in turn affects the machining effect on the workpiece. 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 has the problem that the milling cutter rotates at high speed during operation and the milling cutter cuts the workpiece through friction, and that the heat dissipation of the milling cutter is achieved solely through the heat dissipation holes, the effect is poor, resulting in the milling cutter temperature not being able to drop effectively, which in turn affects the machining effect on the workpiece.
[0007] To achieve the above objectives, this utility model provides the following technical solution:
[0008] A stepped-diameter high-temperature alloy deep groove milling cutter includes a milling cutter head, one end of which is welded with a connector, and a cooling mechanism for cooling the milling cutter is connected to the right side of the connector. A disassembly mechanism for disassembling the milling cutter is provided on one side of the cooling mechanism.
[0009] The cooling mechanism includes a milling cutter shank, which is connected to the right side of the connector. A connecting hole is provided at the end of the milling cutter shank, and a flow cavity is connected to one side of the connecting hole. A water spray hole is provided on the outer surface of the milling cutter head.
[0010] As a further improvement of this utility model: a connecting seat is fixed to the inner wall of the connecting hole, and a limit ring is rotatably connected inside the connecting seat.
[0011] As a further improvement of this utility model: one end of the milling cutter head is connected to a locking block that is fixedly connected to the connecting member.
[0012] As a further improvement of this utility model, the connector has a first flow hole that communicates with the water spray hole.
[0013] As a further improvement of this utility model, the card block has a second flow hole that communicates with the first flow hole.
[0014] As a further improvement of this utility model, a chip removal groove is provided on the outer surface of the milling cutter head.
[0015] As a further embodiment of this utility model: the disassembly mechanism includes a fixing bolt, which is placed on the outside of the milling cutter shank, and the outer surface of the milling cutter shank has a mounting hole that matches the fixing bolt.
[0016] As a further embodiment of this utility model: the end of the fixing bolt is connected to a limiting hole opened on the locking block, and the right side of the locking block is connected to an installation groove opened on the inner wall of the milling cutter shank.
[0017] Compared with the prior art, the beneficial effects of this utility model are:
[0018] 1. In this utility model, the sprayed coolant flows out from the inside of the hole. When the coolant passes through the chip removal groove on the milling cutter head, it can cool down the milling cutter head and flush out the waste chips in the chip removal groove, effectively cooling down the cutter head and assisting in chip removal.
[0019] 2. This utility model loosens the fixing bolt, separating it from the limiting hole on the clamping block. With the cooperation of the mounting groove, the milling cutter head can be separated from the milling cutter shank, allowing for individual disassembly and replacement of the milling cutter head, which is convenient for use.

[0026] 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.
[0027] Many specific details are set forth in the following description in order 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. 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.
[0028] Secondly, 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. Example 1
[0029] Please see Figures 1-5 This is the first embodiment of the present utility model. This embodiment provides a stepped variable diameter high temperature alloy deep groove milling cutter, including a milling cutter head 1. A connecting member 2 is welded to one end of the milling cutter head 1. A cooling mechanism for cooling the milling cutter is connected to the right side of the connecting member 2. A disassembly mechanism for disassembling the milling cutter is provided on one side of the cooling mechanism.
[0030] The cooling mechanism includes a milling cutter holder 3, which is connected to the right side of the connector 2. A connecting hole 31 is provided at the end of the milling cutter holder 3, and a flow cavity 32 is connected to one side of the connecting hole 31. A water spray hole 34 is provided on the outer surface of the milling cutter head 1.
[0031] Specifically, a connecting seat 36 is fixed to the inner wall of the connecting hole 31, and a limit ring 35 is rotatably connected inside the connecting seat 36.
[0032] Furthermore, the delivery pipe is connected and fixed to the limiting ring 35 on the connecting seat 36, so that the coolant can enter the flow chamber 32.
[0033] Specifically, one end of the milling cutter head 1 is connected to a locking block 33 that is fixedly connected to the connecting piece 2.
[0034] Furthermore, the coolant can enter the flow chamber 32, and then enter the first flow hole 4 inside the connector 2 through the second flow hole 5 on the block 33.
[0035] Specifically, the connector 2 has a first flow hole 4 that communicates with the water spray hole 34.
[0036] Furthermore, the coolant flows into the milling cutter head 1 through the first flow hole 4 and is sprayed out through the water spray hole 34. When the coolant passes through the chip removal groove 6 on the milling cutter head 1, it can cool down the milling cutter head 1.
[0037] In use, the milling cutter is connected to the output end of the machine tool. By fixing the milling cutter shank 3 to the output end of the machine tool, the machine tool can drive the milling cutter shank 3 to rotate, thereby driving the milling cutter head 1 to perform cutting operations on the workpiece. A coolant delivery pipe is inserted into the connection hole 31 on the milling cutter shank 3, and the delivery pipe is connected and fixed to the limiting ring 35 on the connecting seat 36, so that the coolant can enter the flow chamber 32, and then enter the first flow hole 4 inside the connecting member 2 through the second flow hole 5 on the locking block 33. The coolant flows into the milling cutter head 1 through the first flow hole 4 and is sprayed out through the water spray hole 34. When the milling cutter head 1 drills a hole in the workpiece, the sprayed coolant will flow out from the inside of the hole to the outside. When the coolant passes through the chip removal groove 6 on the milling cutter head 1, it can cool down the milling cutter head 1 and flush out the waste chips in the chip removal groove 6, effectively cooling down and achieving the function of assisting chip removal.
[0038] In summary, when this stepped-diameter high-temperature alloy deep groove end mill is in use, the sprayed coolant flows out from the inside of the hole to the outside. When the coolant passes through the chip removal groove 6 on the end mill head 1, it can cool down the end mill head 1 and flush out the waste chips in the chip removal groove 6, effectively cooling down the end mill head 1 and achieving the function of assisting chip removal. Example 2
[0039] Please see Figures 1-5 This is the second embodiment of the present utility model.
[0040] Specifically, the inside of the card block 33 is provided with a second flow hole 5 that communicates with the first flow hole 4, and the outer surface of the milling cutter head 1 is provided with a chip removal groove 6.
[0041] Furthermore, the chip removal groove 6 facilitates the removal of waste chips generated during workpiece processing.
[0042] Specifically, the disassembly mechanism includes a fixing bolt 7, which is placed on the outside of the milling cutter holder 3. The outer surface of the milling cutter holder 3 is provided with a mounting hole 73 that matches the fixing bolt 7.
[0043] Furthermore, by loosening the fixing bolt 7, the fixing bolt 7 is separated from the limiting hole 71 on the locking block 33.
[0044] Specifically, the end of the fixing bolt 7 is connected to a limiting hole 71 opened on the locking block 33, and the right side of the locking block 33 is connected to a mounting groove 72 opened on the inner wall of the milling cutter holder 3.
[0045] Furthermore, remove the fixing bolt 7 from the mounting hole 73 to release the fixing of the retaining block 33, and then disassemble and replace the milling cutter head 1 separately.
[0046] In use, the fixing bolt 7 on the milling cutter holder 3 is loosened to separate the fixing bolt 7 from the limiting hole 71 on the locking block 33. The fixing bolt 7 is then removed from the mounting hole 73 to release the locking block 33. With the cooperation of the mounting groove 72, the milling cutter head 1 can be separated from the milling cutter holder 3, and the milling cutter head 1 can be disassembled and replaced separately, improving its practicality.
[0047] In summary, when this stepped-diameter high-temperature alloy deep groove end mill is in use, the sprayed coolant flows out from the inside of the hole to the outside. When the coolant passes through the chip removal groove 6 on the end mill head 1, it can cool down the end mill head 1 and flush out the waste chips in the chip removal groove 6, effectively cooling down the end mill head and assisting in chip removal. Furthermore, by loosening the fixing bolt 7, the fixing bolt 7 is separated from the limiting hole 71 on the retaining block 33, allowing the end mill head 1 to be separated from the end mill shank 3 for individual disassembly and replacement.
