Technical Field

[0001] This utility model relates to the field of milling technology, specifically to a milling tool for rapidly machining the end face of a rotating body. Background Technology

[0002] Machining of rotating body end faces is an important technology in the field of machining. It involves processing the end faces of parts with rotating motion components (such as shafts and discs). This machining method is widely used in many industrial sectors, such as aerospace, shipbuilding, automobile manufacturing, and machinery manufacturing. With the continuous development of industrial technology, the requirements for machining the end faces of rotating bodies are becoming increasingly stringent, including higher machining accuracy, more complex machining shapes, and more efficient machining processes.

[0003] In the marine industry, such as in ship cranes, deck cranes, and mast slewing devices, rotating parts require high-precision end-face machining. Even minute errors can significantly impact product performance. The shapes of rotating body end faces vary, from simple planes to complex curved surfaces, all requiring precise machining techniques. Rotating body end faces can be made of various materials, including metals and non-metals, each with different machining characteristics, posing different challenges to machining techniques.

[0004] Currently, the machining of the end face of a rotating body is still carried out using CNC lathes, with programs written according to the requirements of different shapes. However, while ensuring accuracy, the machining efficiency is slow and the operation is complex, especially during batch production, which requires repeated clamping of the workpiece, resulting in a large workload and low efficiency. Utility Model Content

[0006] To achieve the above objectives, this utility model provides the following technical solution: a milling tool for rapidly machining the end face of a rotating body, comprising a tool body and a three-bladed cutting edge. The tool body is a cylindrical body composed of two cylinders, one large and one small. The inner cavity of the tool body has an irregular inner hole, and three bosses are provided in the inner hole. A mounting buckle is provided at the end face of the large cylinder of the tool body, and a stop buckle is provided at the axial face of the small cylinder of the tool body. The stop buckles are evenly distributed in two. The three-bladed cutting edge is installed in the inner hole. The three-bladed cutting edge is composed of three identical cutting edges. During installation, the three-bladed cutting edge is fixed to the bosses. Both the upper and lower end faces of the three-bladed cutting edge have cutting edges.

[0007] Preferably, the inner hole of the main body has the function of storing chips.

[0008] Preferably, the main body has two sets of mounting buckles, and the two sets of mounting buckles are evenly distributed, with each set of mounting buckles having a different diameter.

[0009] Preferably, the three-bladed cutting edge is a curved surface or an inclined surface.

[0010] Preferably, the three-bladed cutting edge is installed into the body by cold assembly.

[0011] Preferably, the angles of the three blades of the three-bladed cutting edge are 118°, 117°, and 125°, respectively.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. It can effectively solve the problems of high labor intensity and low processing efficiency; by changing the three-bladed cutting edge with different coatings, it is suitable for many difficult-to-machine materials, such as titanium alloys and high-temperature alloys.

[0014] 2. Simple operation, reduced processing difficulty, easy for ordinary operators to process, simple overall tool structure, easy maintenance, wear-resistant three-blade cutting edge can be sharpened and replaced, reducing tool usage cost, since the upper and lower structures of the three-blade cutting edge are the same, both ends of the tool can be processed, and two workpieces can be processed at one time.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1-4 This utility model provides a technical solution: a milling tool for rapidly machining the end face of a rotating body, comprising a tool body 1 and a three-bladed cutting edge 2. The tool body 1 is generally cylindrical, composed of two cylinders, one large and one small. The inner cavity of the tool body 1 has an irregular inner hole 3, which is machined using wire cutting. The inner hole 3 of the body 1 has the function of storing chips. Three bosses 4 are provided inside the inner hole 3. A mounting buckle 5 is provided at the end face of the large cylinder of the tool body 1. The mounting buckle 5 of the body 1 has two sets, and the two sets of mounting buckles 5 are evenly distributed. The diameter of each set of mounting buckles 5 is different. For different installation wrenches, a stop buckle 6 is provided at the small cylindrical shaft surface of the tool body 1, and the stop buckle 6 is two evenly distributed. The shape of the stop buckle 6 is adjusted according to the existing equipment. A three-bladed cutting edge 2 is installed in the inner hole 3. The three-bladed cutting edge 2 is composed of three identical cutting edges. During installation, the three-bladed cutting edge 2 is fixed on the boss 4. Both the upper and lower end faces of the three-bladed cutting edge 2 have cutting edges. The three-bladed cutting edge 2 is a curved surface or an inclined surface. The three-bladed cutting edge 2 is installed into the body 1 by cold assembly. The angles of the three blades of the three-bladed cutting edge 2 are 118°, 117° and 125° respectively.

[0023] More specifically, the tool body 1 consists of two cylinders of different sizes, and the whole is cylindrical, which helps to adapt to machine tool interfaces or processing requirements of different sizes.

[0024] More specifically, the inner hole 3 is machined using wire cutting technology. Its irregular shape has the function of storing chips, which helps to reduce chip interference during processing and improve processing quality and speed.

[0025] More specifically, the large cylindrical end face of the tool body 1 is provided with two sets of mounting buckles 5, each with a different diameter, which are adapted to different mounting wrenches, increasing the flexibility and applicability of the installation. The shape of the stop buckle 6 on the small cylindrical shaft face can be adjusted according to the existing equipment to ensure the stability of the tool during the processing.

[0026] More specifically, the three-bladed cutting edge 2 can machine curved or inclined surfaces. It is installed into the tool body through cold assembly technology and fixed on three bosses 4 in the inner hole. Each cutting edge has a cutting edge on the upper and lower end faces, which may help to make use of both sides and improve the efficiency of tool use.

[0027] More specifically, the angles of the three cutting edges are 118°, 117°, and 125°, respectively. This uneven angle distribution helps to optimize the distribution of cutting forces, reduce vibration, and improve machining accuracy.
