Description

Technical Field

[0001] This application relates to the field of side end mill technology, and in particular to a side end mill that is easy to disassemble and install. Background Technology

[0002] Currently, side end mills are milling tools used for machining the sides of sheet metal or workpieces. Their cutting edges are distributed circumferentially and laterally, allowing for simultaneous radial and axial cutting. They are suitable for machining sides, stepped surfaces, grooves, and small-area planes. They feature a multi-tooth design, high rigidity, and efficient cutting. Common types include integral, indexable, and welded types, and they are widely used in metal processing, mold making, aerospace, and automotive manufacturing.

[0003] Chinese Patent CN116829287A discloses a side milling cutter having a body and a disc-shaped tool holder. The body extends along a predetermined axis of rotation from a first end having an interface for connection to a rotary drive to a free second end. A support surface for the disc-shaped tool holder is formed on the free second end. The disc-shaped tool holder is fastened to the second end and supported on the support surface by a first main surface facing the body. The outer periphery of the tool holder projects radially from the body and has an axial through-hole extending through the center of the disc-shaped tool holder. Multiple coolant supply channels are formed in the body for supplying coolant to the second end of the body. Multiple coolant distribution channels are formed on the disc-shaped tool holder for supplying coolant to the outer periphery of the tool holder.

[0004] In related technologies, the tool body is mounted on a connecting shaft. If there is a gap between the tool body and the connecting shaft during use, the tool body will wobble during machining. If the inner diameter of the tool body is machined to fit the connecting shaft perfectly during machining, the tool body will become more difficult to install if it expands due to heat during installation. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a side end mill that is easy to disassemble and install, which solves the technical problem.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A side end mill that is easy to disassemble and install includes a tool holder, the tool holder having a tapered hole axially for mounting a cutting tool, a plurality of mounting blocks evenly distributed circumferentially on the tool holder, a radially extending tool groove formed between adjacent mounting blocks, a cutting tool being detachably mounted in the tool groove, and a fixing member for fixing the cutting tool on the tool holder.

[0008] Furthermore, the fixing component includes a fixing post, on which a fixing bolt is threadedly connected, and one end of the fixing bolt passes through the fixing post.

[0009] Furthermore, a support slope is formed on one side of the mounting block, and the blade abuts against the support slope, with the support slope supporting the blade.

[0010] Furthermore, a lifting surface is formed on the fixing bolt, the lifting surface facing the side close to the blade, and the lifting surface abuts against the blade.

[0011] Furthermore, the mounting block has anti-slip textures formed on one side of the support slope, and the blade abuts against the anti-slip textures.

[0012] Furthermore, a keyway is provided on the tool holder, and the keyway communicates with the tapered hole.

[0013] Furthermore, the cutting groove is inclined relative to the axis of the tool holder so that when the cutting blade is subjected to force during processing, it presses the tool holder against the connecting shaft.

[0022] In order to make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0023] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0024] This application discloses a side end mill that is easy to disassemble and install.

[0025] Reference Figure 1 A side end mill that is easy to disassemble and install includes a tool holder 1 with a tapered hole 11, through which the tool holder 1 is mounted on a connecting shaft. Mounting blocks 2 are provided on the tool holder 1, with several mounting blocks 2 spaced apart. A groove 21 is formed between two adjacent mounting blocks 2, and a cutting insert 211 is installed in the groove 21. A fixing member 3 is provided on the tool holder 1 for mounting the cutting insert 211 onto the tool holder 1.

[0026] The tool holder 1 is cylindrical in shape. A tapered hole 11 extending axially is formed at the center of the tool holder 1, penetrating the tool holder 1. The inner wall of the tapered hole 11 has a tapered surface structure and gradually narrows axially to ensure a tight fit with the tapered shank of the connecting shaft. In use, to improve the stability between the tool holder 1 and the connecting shaft, a keyway 12 is provided on the tool holder 1. The keyway 12 communicates with the tapered hole 11 on the tool holder 1. During use, the key block on the connecting shaft engages with the keyway 12 on the tool holder 1, thereby preventing relative rotation between the tool holder 1 and the connecting shaft when the connecting shaft rotates the tool holder 1.

[0027] Reference Figure 2 A plurality of mounting blocks 2 are evenly spaced around the axis of the tool holder 1, and these mounting blocks 2 are integrally formed with the tool holder 1. A groove 21 is formed between two adjacent mounting blocks 2. Furthermore, the groove 21 is inclined relative to the axis of the tool holder 1. When the tool is used to process the side of the sheet metal, the sheet metal will generate a reaction force on the blade 211, causing the blade 211 to press the tool holder 1 against the connecting shaft during processing. If the shaft hole in the tool holder 1 is a conventional round hole design, the tool holder 1 is prone to detaching from the connecting shaft as the tool processes the sheet metal. By inclining the groove 21, the risk of the tool holder 1 detaching from the connecting shaft during processing is reduced.

[0028] In existing technologies, left-hand and right-hand cutting tools typically have different structures, requiring separate design and manufacturing, which increases production and usage costs. To address this, this application employs a special tilting design for the tool groove 21 to make it compatible with both left-hand and right-hand cutting tools, thereby achieving tool versatility. This design not only simplifies the structure of the tool holder 1 but also improves tool adaptability and flexibility, reducing inventory and replacement costs.

[0029] Reference Figures 2-3 Furthermore, to improve the stability of the blade 211 on the tool holder 1, a supporting inclined surface 22 is formed on the side of the mounting block 2 near the blade 211. The supporting inclined surface 22 is inclined towards the side near the blade 211, and anti-slip texture 23 is formed on the side of the mounting block 2 near the supporting inclined surface 22. In use, the blade 211 is pressed against the supporting inclined surface 22 of the mounting block 2. In addition, the fixing member 3 includes a fixing post 31, which is located on the side of the blade 211 opposite to the anti-slip texture 23 on the supporting block. The fixing post 31 has a lifting surface 32, which is pressed against the blade 211 in use.

[0030] A fixing bolt 33 is provided on the fixing post 31. The fixing bolt 33 is coaxially arranged with the fixing post 31 and threadedly connected to the fixing post 31, with one end of the fixing bolt 33 protruding from the fixing post 31. In use, rotating the fixing bolt 33 causes one end of the fixing bolt 33 to press against the tool holder 1. As the fixing bolt 33 rotates, the fixing post 31 moves away from the tool holder 1. As the fixing post 31 moves away from the tool holder 1, the lifting surface 32 of the fixing post 31 presses against the blade 211. The fixing post 31 moves the blade 211 away from the tool holder 1. Since the supporting inclined surface 22 on the mounting block 2 is inclined, the blade 211 is pressed against the supporting inclined surface 22 of the mounting block 2 by the fixing post 31.

[0031] When it is necessary to remove the tool holder 1 from the connecting shaft, it is only necessary to use the lifting cylinder to separate the tool holder 1 from the connecting shaft. Due to the internal control on the tool holder 1, the lifting cylinder can easily remove the tool holder 1 from the connecting shaft simply by separating the tool holder 1 from the connecting shaft. Compared with the prior art, where the cross-section of the inner hole is circular and the lifting cylinder needs to continuously lift the tool holder 1, this application greatly improves the convenience of removing the tool holder 1 from the connecting shaft.

[0032] The side milling cutter of this application is mainly used for processing copper strip, and the side milling cutter is used in pairs. When in use, the two side milling cutters respectively process the two sides of the copper strip.

[0033] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
