Description

Technical Field

[0001] This invention relates to the field of cutting technology, and more particularly to a milling cutter with an adjustable cutting angle. Background Technology

[0002] Milling cutters are rotary cutting tools used for milling operations. They remove excess material from the workpiece through intermittent cutting with their teeth. They are mainly used for machining planes, steps, grooves, shaped surfaces, and cutting off workpieces. Their structures are divided into three categories: integral, insert-tooth, and indexable. According to their functions, they can be divided into cylindrical milling cutters, face milling cutters, end mills, three-sided milling cutters, etc. The geometric angles of milling cutters include the rake angle, clearance angle, principal cutting edge angle, and cutting edge inclination angle. The materials commonly used are high-speed tool steel and cemented carbide.

[0003] The existing cutting device is a single milling cutter, which is usually installed by tightening bolts. In the current cutting process, because it is necessary to perform deep cutting on irregular parts, the milling cutter needs to be changed frequently to perform deep cutting on irregular parts, which greatly affects the production efficiency. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides an adjustable cutting angle milling cutter, which solves the problems mentioned in the background section.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: An adjustable cutting angle milling cutter includes a base, a milling cutter bed on the top of the base, a lifting platform on one side of the milling cutter bed, a cross slide on the top of the lifting platform, a worktable on the top of the cross slide, a suspension beam on the top of the milling cutter bed, a tool holder support on the side of the suspension beam near the worktable, a drive motor on the top of the tool holder support, a quick-release mechanism at the bottom of the tool holder support, an adjustable milling cutter mechanism at the bottom of the quick-release mechanism, the quick-release mechanism consisting of a mounting plate assembly and a centrifugal clamp assembly, and the adjustable milling cutter mechanism consisting of a milling cutter fixing rod assembly and a milling cutter head assembly. The mounting plate assembly is used to install the milling cutter fixing rod assembly, enabling quick assembly and disassembly of the milling cutter head assembly; the centrifugal force clamp assembly is used to clamp and lock the milling cutter fixing rod assembly using centrifugal force. The centrifugal force clamp assembly distributes the centrifugal force evenly onto the milling cutter fixing rod assembly to prevent displacement, thereby effectively improving machining accuracy.

[0006] Furthermore, the milling cutter bed is located on one side of the top of the base, and the drive motor, tool holder, quick assembly / disassembly mechanism, and adjustable milling cutter mechanism are all located above the slide, lifting platform, and worktable. Moreover, the slide, lifting platform, worktable, drive motor, tool holder, quick assembly / disassembly mechanism, and adjustable milling cutter mechanism are all located on the top of the base away from the side of the milling cutter bed.

[0007] Furthermore, the mounting plate assembly includes a mounting ring, an annular outer shell on the top outer side of the mounting ring, an annular inner sleeve on the top inner side of the mounting ring, uniformly distributed limiting vertical rods inside the inner sleeve, an annular elastic mounting ring on the upper part of the inner wall of the inner sleeve, and uniformly distributed entry grooves penetrating the outer wall of the inner sleeve below the elastic mounting ring, with the entry grooves all located between the limiting vertical rods. Mounting brackets are provided on both sides of the entry grooves on the outer wall of the inner sleeve.

[0008] Furthermore, the centrifugal clamp assembly includes a centrifugal clamp, and each centrifugal clamp has a counterweight at the end away from the inner sleeve. Each centrifugal clamp has a connecting block at the lower bend on the side away from the inner sleeve. Each connecting block has a torsion spring groove running through it. Each centrifugal clamp has mirror-symmetrical meshing teeth at the end near the inner sleeve, and each torsion spring groove has a torsion spring.

[0009] Furthermore, the centrifugal clamps are all located between the mounting brackets, and the centrifugal clamps are all connected to the mounting brackets through torsion springs. The elastic mounting ring is a concave ring with an inward diameter, and the elastic mounting ring is made of an elastic metal material. The bottom part of the centrifugal clamp and the inner sleeve are both located between the inlet grooves.

[0010] Furthermore, the milling cutter fixing rod assembly includes a milling cutter mounting rod. The outer wall of the milling cutter mounting rod has a limiting vertical groove, and the limiting vertical groove is evenly distributed on the outer wall of the milling cutter mounting rod. A surrounding mounting groove is formed above the outer wall of the milling cutter mounting rod. The outer wall of the milling cutter mounting rod below the mounting groove has a meshing groove evenly distributed between the opposite limiting vertical grooves, and the meshing grooves between the opposite limiting vertical grooves are all mirror symmetrical. The milling cutter mounting rod is located inside the inner sleeve.

[0011] Furthermore, the milling cutter head assembly includes a connecting plate, and a milling cutter mounting bracket is provided at the bottom of the connecting plate. The outer wall of the end of the milling cutter mounting bracket away from the milling cutter mounting rod has mutually offset and symmetrical adjusting milling cutter clearance grooves on both sides. Each adjusting milling cutter clearance groove has a mutually offset and symmetrical milling cutter clamp. Each milling cutter clamp has a milling cutter clamping groove at the end away from the milling cutter mounting bracket, and each milling cutter clamping groove has a milling cutter. Each milling cutter has a waste material discharge groove at the end away from the milling cutter clamp. An angle adjusting bolt is provided through the outer wall of each milling cutter clamp away from the adjusting milling cutter clearance groove.

[0012] Furthermore, the connecting plate is fixed to one end of the bottom of the milling cutter mounting rod. When the milling cutter mounting rod is inside the inner sleeve, the limiting vertical rods are all located in the limiting vertical grooves, which provide lateral limiting for the milling cutter mounting rod. When the milling cutter mounting rod is inside the inner sleeve, the elastic mounting ring and the mounting groove are engaged, which provides vertical limiting for the milling cutter mounting rod. When the milling cutter mounting rod is inside the inner sleeve, the meshing groove and the entry groove correspond one-to-one.

[0013] Compared with existing technologies, the advantages of this invention are: 1. The centrifugal clamp automatically clamps the milling cutter using the centrifugal force generated during high-speed rotation during milling. When rotation stops, the torsion spring automatically releases it. The operation is simple and can complete the installation and removal of the milling cutter in a short time, reducing the time for changing milling cutters, reducing equipment downtime, and improving work efficiency.

[0014] 2: The cooperation between the centrifugal clamp assembly and the elastic mounting ring structure in the quick-release mechanism ensures that the milling cutter is stably fixed during high-speed rotation and machining, preventing loosening and falling off, and ensuring safe and stable machining. The centrifugal clamp assembly distributes centrifugal force evenly to the milling cutter fixing rod assembly to prevent milling cutter offset, thereby effectively improving machining accuracy.

[0015] 3: The adjustable milling cutter mechanism is equipped with staggered and symmetrically distributed milling cutters. When cutting chamfers or fillets, the angle can be adjusted. When cutting planar objects, the staggered and symmetrical milling cutters can be adjusted to be parallel to each other, realizing the multi-functional cutting function of the milling cutter and achieving the function of one cutter head for multiple purposes.

Detailed Implementation

[0018] Example 1

[0019] Reference Figures 1-8 An adjustable cutting angle milling cutter includes a base 1, a milling cutter bed 2 on the top of the base 1, a lifting platform 5 on one side of the milling cutter bed 2, a cross slide 4 on the top of the lifting platform 5, a worktable 6 on the top of the cross slide 4, a suspension beam 3 on the top of the milling cutter bed 2, a tool holder 8 on the side of the suspension beam 3 near the worktable 6, a drive motor 7 on the top of the tool holder 8, a quick disassembly and assembly mechanism 9 at the bottom of the tool holder 8, and an adjustable milling cutter mechanism 10 at the bottom of the quick disassembly and assembly mechanism 9. The quick disassembly and assembly mechanism 9 is composed of a mounting plate assembly 91 and a centrifugal clamp assembly 92, and the adjustable milling cutter mechanism 10 is composed of a milling cutter fixing rod assembly 101 and a milling cutter head assembly 102. Mounting plate assembly 91 is used to mount milling cutter fixing rod assembly 101, enabling quick assembly and disassembly of milling cutter head assembly 102; centrifugal force clamp assembly 92 is used to clamp and lock milling cutter fixing rod assembly 101 by centrifugal force. Centrifugal force clamp assembly 92 applies centrifugal force evenly to milling cutter fixing rod assembly 101 to avoid displacement, thereby effectively improving machining accuracy.

[0020] The milling cutter unit is equipped with a base 1, which serves as the basic support component of the entire unit, providing a stable working platform for other components and ensuring the stability of the unit during processing, reducing processing errors caused by vibration. On top of the base 1, a milling cutter bed 2 is installed. The milling cutter bed 2 is the core frame structure of the entire milling cutter unit, supporting multiple key components and providing the necessary space and structural support for the installation and operation of each component. A lifting platform 5 is installed on one side of the milling cutter bed 2. The lifting platform 5 has a height adjustment function, allowing for precise adjustment of its height according to different processing requirements, thereby changing the relative position of the worktable 6 to adapt to the processing of workpieces of different sizes and the requirements of different processing techniques. A cross slide 4 is located on top of the lifting platform 5, which can move horizontally, further expanding the horizontal processing range of the worktable 6, enabling multi-position processing of workpieces on the horizontal plane, meeting diverse processing needs. The worktable 6 is placed on top of the cross slide 4. The worktable 6 is a platform for placing the workpiece to be processed; its surface is flat and has sufficient strength and rigidity to stably support the workpiece. To ensure the workpiece does not move or deform during milling and to guarantee machining accuracy, a cantilever beam 3 is installed on the top of the milling cutter bed 2. The cantilever beam 3 extends towards the worktable 6, providing an installation position for the tool holder 8, which supports and fixes the tool holder 8, allowing it to be stably positioned in a suitable working position. The tool holder 8, as the support structure for the milling cutter, is reasonably designed to firmly fix the milling cutter and withstand various forces generated during milling, ensuring the stability and reliability of the milling cutter during machining. A drive motor 7 is installed on the top of the tool holder 8, which is the power source for the entire milling cutter. Through its own rotational motion, the drive motor 7 transmits power to the milling cutter, driving it to rotate at high speed to achieve cutting. A quick-release mechanism 9 is provided at the bottom of the tool holder 8. The quick-release mechanism 9 is ingeniously designed and easy to operate, enabling the installation and removal of the milling cutter in a short time. This not only greatly improves work efficiency and reduces the time for changing milling cutters, but also facilitates the maintenance and upkeep of the milling cutter, reducing equipment downtime.

[0021] The milling cutter bed 2 is located on one side of the top of the base 1. The drive motor 7, the tool holder 8, the quick disassembly and assembly mechanism 9, and the adjustable milling cutter mechanism 10 are all located above the slide 4, the lifting platform 5, and the worktable 6. The slide 4, the lifting platform 5, the worktable 6, the drive motor 7, the tool holder 8, the quick disassembly and assembly mechanism 9, and the adjustable milling cutter mechanism 10 are all located on the top of the base 1 on the side away from the milling cutter bed 2.

[0022] Above the slide plate 4, lifting platform 5, and worktable 6, the drive motor 7, tool holder support 8, quick-release mechanism 9, and adjustable milling cutter mechanism 10 are arranged in sequence. The drive motor 7, as the power source for the entire machining process, acts like the heart of the equipment, generating powerful force through high-speed rotation to provide energy for the cutting motion of the milling cutter. The adjustable milling cutter mechanism 10 is a major highlight of this equipment. It possesses a unique mechanical structure that allows for precise adjustment of the milling cutter's cutting angle according to specific machining requirements. By changing the cutting angle, it enables efficient machining of workpieces of different shapes and materials, meeting the demands of modern manufacturing for diversified and high-precision product processing.

[0023] Example 2

[0024] The mounting plate assembly 91 includes a mounting ring 901. The top outer side of the mounting ring 901 is provided with an annular outer shell 902. The top inner side of the mounting ring 901 is provided with an annular inner sleeve 903. The inner sleeve 903 is provided with evenly distributed limiting vertical rods 907. The upper part of the inner wall of the inner sleeve 903 is provided with an annular elastic mounting ring 908. The outer wall of the inner sleeve 903 is provided with evenly distributed entry grooves 909 below the elastic mounting ring 908, and the entry grooves 909 are all located between the limiting vertical rods 907. The outer wall of the inner sleeve 903 is provided with mounting brackets 904 on both sides of the entry grooves 909.

[0025] An annular inner sleeve 903 is installed on the inner side of the top of the mounting ring 901. The inner sleeve 903 is one of the core components of the quick-release mechanism 9. The inner sleeve 903 directly cooperates with the mounting part of the milling cutter to realize the fixing and removal of the milling cutter. The inner diameter of the inner sleeve 903 is precisely designed to closely match the mounting part of the milling cutter, ensuring that the milling cutter can be stably fixed in the inner sleeve 903 after installation, and will not loosen or shake during the machining process. When the milling cutter is inserted into the inner sleeve 903, the limiting vertical rod 907 can ensure that the milling cutter accurately reaches the predetermined position, preventing machining errors caused by installation position deviations, and at the same time limiting... The vertical rod 907 can also withstand a certain lateral force, enhancing the stability of the milling cutter during the machining process. During the installation of the milling cutter, the elastic mounting ring 908 can undergo elastic deformation, providing a certain buffer and guidance for the insertion of the milling cutter, allowing the milling cutter to smoothly enter the inner sleeve 903. After the milling cutter is installed in place, the elastic mounting ring 908 returns to its original shape, tightly locking the milling cutter, further enhancing the fixing effect of the milling cutter and preventing the milling cutter from falling off due to vibration during the machining process. The outer wall of the inner sleeve 903 is provided with mounting brackets 904 on both sides of the entry groove 909. The mounting brackets 904 provide installation positions for other auxiliary components or disassembly tools.

[0026] The centrifugal clamp assembly 92 includes a centrifugal clamp 905. Each centrifugal clamp 905 is provided with a counterweight 910 at the end away from the inner sleeve 903. Each centrifugal clamp 905 is provided with a connecting block 911 at the lower bend on the side away from the inner sleeve 903. Each connecting block 911 is provided with a torsion spring groove 912. Each centrifugal clamp 905 is provided with mutually mirror-symmetrical meshing teeth 913 at the end near the inner sleeve 903. Each torsion spring 906 is provided in the torsion spring groove 912.

[0027] The centrifugal clamp 905, as a core functional component of the quick-release mechanism 9, is designed to play a crucial role when the milling cutter rotates at high speed, ensuring precise clamping force under centrifugal force. At the end of the centrifugal clamp 905 furthest from the inner sleeve 903, a counterweight 910 is installed. Its function is to utilize the principle of centrifugal force to cause the centrifugal clamp 905 to move outwards when the milling cutter rotates at high speed. When the milling cutter begins to rotate at high speed, the counterweight 910 is subjected to a strong centrifugal force, causing the centrifugal clamp 905 to expand outwards as a whole. The centrifugal clamp 905 is tightly clamped, ensuring that the milling cutter will not loosen or fall off due to vibration or external force during machining, greatly improving the safety and stability of machining. A connecting block 911 is provided at the bend on the side of the centrifugal clamp 905 away from the inner sleeve 903. The connecting block 911 is a key part connecting the centrifugal clamp 905 and the torsion spring 906, capable of withstanding the elastic force generated by the torsion spring 906. A torsion spring groove 912 is provided through each connecting block 911. The size and shape of the torsion spring groove 912 perfectly match the torsion spring 906, ensuring the torsion spring 906... 06 provides a stable mounting position. The torsion spring 906 is installed in the torsion spring groove 912. It is an elastic mechanical part that can undergo elastic deformation when subjected to external force and return to its original shape after the external force is removed. When the milling cutter stops rotating and the centrifugal force disappears, the torsion spring 906, relying on its own elastic force, pulls the centrifugal clamp 905 back to its initial position, causing the centrifugal clamp 905 to loosen its clamping of the milling cutter. This facilitates the operator to quickly disassemble the milling cutter, realizing automatic clamping of the milling cutter during high-speed rotation and automatic release after rotation stops. The disassembly and assembly process has been greatly simplified, and work efficiency has been improved. The centrifugal clamp 905 has mirror-symmetrical meshing teeth 913 on one end near the inner sleeve 903. The meshing teeth 913 are designed to enhance the connection strength and stability between the centrifugal clamp 905 and the milling cutter. When the centrifugal clamp 905 clamps the milling cutter under the action of centrifugal force, the meshing teeth 913 can mesh with the corresponding structure on the milling cutter to form a mechanical interlocking effect, further preventing the milling cutter from sliding or falling off during the machining process, and ensuring machining accuracy and quality.

[0028] Centrifugal clamps 905 are all located between the mounting brackets 904. Centrifugal clamps 905 are all connected to the mounting brackets 904 through torsion springs 906. The elastic mounting ring 908 is a concave ring with an inward diameter and is made of elastic metal material. The bottom part of the centrifugal clamp 905 and the inner sleeve 903 are located between the inlet grooves 909.

[0029] Centrifugal clamps 905 are specifically positioned within the quick-release mechanism 9, located opposite each other on the mounting brackets 904. The mounting brackets 904 provide a stable support frame for the centrifugal clamps 905, ensuring they maintain a relatively fixed position under various external forces and guaranteeing the structural stability of the entire mechanism. This relative arrangement also provides sufficient space for the movement of the centrifugal clamps 905, allowing them to freely open and close under centrifugal force, enabling clamping and releasing operations on the milling cutter. When the milling cutter rotates at high speed, the centrifugal clamps 905 expand outwards under the centrifugal force. At this time, the torsion spring 906 is stretched, generating elastic deformation and storing elastic potential energy. When the milling cutter stops rotating and the centrifugal force disappears, the torsion spring 906 quickly returns to its original shape using its stored elastic potential energy, pulling the centrifugal clamps 905 back to their initial position, thus releasing the clamps from the milling cutter. This connection method, achieved through the torsion spring 906, is not only simple and reliable in structure, but also... Furthermore, it can automatically reset the centrifugal clamp 905, greatly improving the automation and efficiency of milling cutter assembly and disassembly. The elastic mounting ring 908 has a unique design feature: it is a concave annular structure. The concave annular design allows the elastic mounting ring 908 to produce a better fit when in contact with the milling cutter, increasing friction and thus more effectively fixing the milling cutter. During the milling cutter installation process, the elastic mounting ring 908 can undergo elastic deformation, providing a certain buffer and guidance for the insertion of the milling cutter, allowing the milling cutter to smoothly enter the inner sleeve 903. After the milling cutter is installed in place, the elastic mounting ring 908 returns to its original shape, tightly locking the milling cutter and preventing it from falling off due to vibration during processing. The bottom part of the centrifugal clamp 905 is located between the entry grooves 909, allowing the operator to easily access the bottom of the centrifugal clamp 905 through the entry grooves 909 when disassembling the milling cutter, and use the appropriate tools to operate the centrifugal clamp 905 to loosen its clamping of the milling cutter. The inner sleeve 903, located between the entry slots 909, provides clear spatial guidance for the insertion and removal of the milling cutter, ensuring that the milling cutter can be accurately installed and removed along the direction of the entry slots 909, thus avoiding problems such as damage to the milling cutter or inaccurate installation due to improper operation.
