Description

Technical Field

[0001] This utility model relates to the field of milling cutter equipment technology, specifically a nano-diamond coated face 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. Milling cutters are mainly used on milling machines to machine planes, steps, grooves, shaped surfaces, and cut off workpieces. Milling cutters used in machining centers mostly adopt a spring collet clamping method, operating in a cantilevered state. During milling operations, sometimes the milling cutter may gradually extend out of the collet clamp, leading to workpiece scrap. This is generally caused by an oil film between the inner hole of the collet clamp and the outer diameter of the milling cutter shank, resulting in insufficient clamping force. Milling cutters are usually coated with anti-rust oil at the factory. If non-water-soluble cutting oil is used during cutting, a misty oil film will also adhere to the inner hole of the collet clamp, making it difficult for the collet clamp to firmly hold the shank. Before clamping the milling cutter, the shank and the inner hole of the collet clamp should be cleaned with cleaning fluid and dried before clamping.

[0003] A publicly available patent (publication number CN218425841U) discloses a multifunctional nanodiamond-coated face milling cutter, comprising a cutter holder, a cutter shank, and a cutter block. The cutter holder is sleeved around the cutter shank, and the cutter block is mounted around the cutter holder. A disassembly / assembly mechanism connects the cutter holder and the cutter shank. The disassembly / assembly mechanism includes a mounting ring plate, a mounting block, a limiting slot, a placement groove, and a limiting insert. The mounting ring plate is fixedly connected to the periphery of the cutter shank, the mounting block is fixedly connected to the upper surface of the cutter holder, the limiting slot is located at the end of the mounting block, the placement groove is located on the upper surface of the mounting ring plate, and the limiting insert is inserted through the end wall of the placement groove. A single-disassembly assembly connects the cutter holder and the cutter block. This invention, by setting up a disassembly / assembly mechanism, allows the cutter holder to be quickly disassembled and assembled from the cutter shank, and further improves the overall stability of the installation, thereby avoiding the unusability caused by loose screws.

[0004] However, there are some problems in the use of existing nanodiamond coated face milling cutters: 1. The coating thickness of the nanodiamond coated face milling cutters currently on the market is relatively thin, making it easy for the coating to peel off, which aggravates the damage to the cutter and increases the overall wear and tear, making it unsuitable for long-term use; 2. The connection stability between the nanodiamond coated face milling cutters and the external environment is relatively low, making installation inconvenient and lacking a stable connection measure. Utility Model Content

[0005] The purpose of this invention is to provide a nanodiamond coated face milling cutter 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 nano-diamond coated face milling cutter, comprising a first cutter body, a cutter body coating assembly disposed at one end of the first cutter body, and a mounting and fixing assembly disposed at the other end of the first cutter body;

[0007] The blade coating assembly includes a second blade connected to one side of the surface of the first blade, a blade head connected to one end of the surface of the second blade, the surface of the blade head being coated with a first coating, and the surface of the blade head being coated with a second coating, thereby coating the blade head with the first coating and the second coating.

[0008] The mounting and fixing assembly includes an insertion hole at one end of the surface of the first cutter body, a plug is connected inside the insertion hole, a base plate is fixedly connected to one end of the plug, and a first fixing hole is opened on the surface of the plug, through which the first cutter body is connected to the outside.

[0009] As a further embodiment of this utility model: the blade coating assembly further includes a blade edge that is connected to the surface of the second blade body, and the surface of the blade edge is coated with a first coating and a second coating.

[0010] As a further embodiment of this utility model: the mounting and fixing assembly further includes a connecting block fixedly connected to one end of the surface of the first blade body, and the surface of the connecting block is provided with a connecting hole.

[0011] As a further improvement of this utility model: a second fixing hole is provided on the surface of the first blade body, and the interior of the second fixing hole communicates with the interior of the insertion hole.

[0012] As a further improvement of this utility model: the interior of the first fixing hole and the interior of the second fixing hole are aligned, and bolts are fitted inside the first fixing hole and the interior of the second fixing hole.

[0013] As a further improvement of this utility model: screws are connected to the four corners of the base plate surface, the first coating and the second coating are made of nano-diamond, and rubber pads are detachably connected to the base plate surface.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] In use, this utility model employs a first cutter body to mount a second cutter body, creating a dual-cutter body combination that enhances overall operability. One end of the second cutter body is connected to the cutter head. By coating the cutter head with a first and a second coating made of nano-diamond, the overall strength is increased, reducing damage to the cutter head. The use of the double coating also extends the overall service life and reduces the likelihood of peeling. Furthermore, the multiple cutting edges connected to the second cutter body are also coated with the double coating, increasing overall practicality. Consequently, the nano-diamond coated end mill has a thicker overall coating thickness, making it less prone to peeling and reducing the risk of further damage to subsequent end mills. This reduces overall wear and tear, facilitating long-term use.

[0016] When the milling cutter needs to be installed, it is connected to a post through an insertion hole on one side of the first cutter body surface. One end of the post is fixedly connected to the base plate surface, and the base plate supports the first cutter body. The first cutter body is aligned with the first fixing hole on the post surface through a second fixing hole on its surface, and a bolt is inserted to stably install the first cutter body on the base plate, increasing the overall connectivity. Thus, the nano-diamond coated milling cutter has high stability in its connection with the outside, making its installation with the outside more convenient and providing a solid connection measure.

Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model. Example 1

[0023] like Figures 1 to 4 As shown, this embodiment provides a nanodiamond coated face milling cutter, including a first cutter body 1, a cutter body coating assembly disposed at one end of the first cutter body 1, and a mounting and fixing assembly disposed at the other end of the first cutter body 1. The cutter body coating assembly includes a second cutter body 201 that is fitted and connected to one side of the surface of the first cutter body 1. A cutter head 202 is fitted and connected to one end of the surface of the second cutter body 201. The surface of the cutter head 202 is coated with a first coating 203 and a second coating 204. The cutter head 202 is coated by the first coating 203 and the second coating 204. The mounting and fixing assembly includes an insertion hole 303 opened at one end of the surface of the first cutter body 1. An insertion post 304 is fitted and connected inside the insertion hole 303. A base plate 305 is fixedly connected to one end of the insertion post 304. A first fixing hole 307 is opened on the surface of the insertion post 304. The first cutter body 1 is connected to the outside through the insertion hole 303. Example 2

[0024] In addition to all the technical features in Embodiment 1, this embodiment also includes: the blade coating assembly further includes a blade 205 that is connected to the surface of the second blade 201. The surface of the blade 205 is coated with a first coating 203 and a second coating 204. The protection of the second blade 201 as a whole is increased by coating the surface of the blade 205 with a double coating.

[0025] Furthermore, the mounting and fixing assembly also includes a connecting block 301 fixedly connected to one end of the surface of the first blade body 1. The surface of the connecting block 301 is provided with a connecting hole 302, and the surface of the first blade body 1 is provided with a second fixing hole 5. The interior of the second fixing hole 5 communicates with the interior of the insertion hole 303. The connecting block 301 contacts the base plate 305, and the connecting block 301 is connected to the bolt 6 through the connecting hole 302 on its surface, so that the connecting block 301 is fixed to the surface of the base plate 305, thereby providing a stable connection between the first blade body 1 and the base plate 305.

[0026] Furthermore, the interiors of the first fixing hole 307 and the second fixing hole 5 are aligned, and bolts 6 are fitted inside the first fixing hole 307 and the second fixing hole 5. Screws 4 are fitted at the four corners of the surface of the base plate 305. The first coating 203 and the second coating 204 are made of nano-diamond. A rubber pad 306 is detachably connected to the surface of the base plate 305. The rubber pad 306 reduces the rigid wear after the first cutter body 1 contacts the base plate 305, thereby increasing its service life. The screws 4 increase the installation connectivity between the base plate 305 and the outside.

[0027] Working Principle: The second cutter body 201 is mounted on the first cutter body 1, creating a dual-cutter body combination that increases overall operability. One end of the second cutter body 201 is connected to the cutter head 202. The cutter head 202 is coated with a first coating 203 and a second coating 204 made of nano-diamond, increasing overall strength and reducing damage. The double coating also extends the overall service life and reduces the likelihood of peeling. The multiple cutting edges 205 connected to the surface of the second cutter body 201 are also coated with the double coating, increasing overall practicality. The double coating on the cutting edges 205 increases the overall protection of the second cutter body 201. Furthermore, the nano-diamond coated end mill has a thicker coating thickness during use, making it less prone to peeling and reducing the risk of further damage to subsequent end mills. This reduces overall wear and tear, facilitating long-term use. The end mill is connected to the base plate 305 via a connecting block 301. The connecting hole 302 on the surface of the first cutter body 1 is connected to the bolt 6, so that the connecting block 301 is fixed on the surface of the base plate 305, thereby stably connecting the first cutter body 1 and the base plate 305. The first cutter body 1 is connected to the insert post 304 through the insertion hole 303 on one side of the surface of the first cutter body 1, and one end of the insert post 304 is fixedly connected to the surface of the base plate 305. The base plate 305 supports the first cutter body 1. The first cutter body 1 is aligned with the first fixing hole 307 on the surface of the insert post 304 through the second fixing hole 5 on the surface of the first cutter body 1, and the bolt 6 is inserted into it. The rubber pad 306 reduces the rigid wear after the first cutter body 1 contacts the base plate 305, increasing its service life. The screw 4 increases the installation connection between the base plate 305 and the outside, and stably installs the first cutter body 1 on the base plate 305, increasing the overall connection. Then, the nano-diamond coated face milling cutter is used, and its overall connection stability with the outside is high, making its overall installation with the outside more convenient and having a solid connection measure.
