Description

Technical Field

[0001] This utility model relates to the field of anti-vibration technology for milling cutters, specifically to an anti-vibration forming milling cutter. Background Technology

[0002] A milling cutter is a rotating cutting tool with one or more cutting teeth used for milling. During operation, each cutting tooth 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. However, during the milling process, because the cutting insert is in direct contact with the workpiece, the tool may vibrate. The resulting vibration will be transmitted along the cutting insert to the tool holder, causing uneven depth of cut on the circumferential cutting edge of the milling cutter and reducing machining accuracy.

[0003] When tool vibration occurs in current milling operations, the cutting speed and feed rate are usually reduced, or the depth of cut is decreased. At this time, the reduction of cutting speed and feed rate is mostly a way to reduce milling cutter chatter from external factors, which leads to a decrease in the efficiency of milling operations. In addition, there may be gaps between the tool and the tool holder when the tool is installed, which can also cause tool vibration. Tool vibration may generate additional noise, reduce machining accuracy, accelerate tool wear, and result in poor performance.

[0004] To address this problem, this application provides a vibration-resistant forming milling cutter. Utility Model Content

[0005] The purpose of this utility model is to provide a vibration-resistant forming milling cutter to solve the problems mentioned in the background art, which are that milling cutters are prone to vibration during processing, resulting in reduced processing accuracy, accelerated tool wear, and poor performance.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0007] A vibration-damping milling cutter includes a tool clamping assembly, a tool assembly, and a vibration-damping component. The tool clamping assembly includes a tool holder body and loading / unloading slots, which are located on both sides of the tool holder body. The vibration-damping component is fixedly installed inside the tool assembly. The tool assembly includes a tool body and a connecting platform, which is fixedly connected to the top of the tool body. The vibration-damping component includes a tool base plate, which is fixedly installed inside the tool body.

[0008] A further improvement of this utility model is that: a tool mounting hole is provided at the bottom of the tool holder body, and a tool slot is provided inside the tool mounting hole.

[0009] A further improvement of this utility model is that a chip removal groove is provided at the bottom of the tool body, and a machining blade is threadedly fixed at the bottom of the tool body.

[0010] A further improvement of this utility model is that: the processing blade is provided with a blade fastening bolt inside, and a washer fixing plate is movably installed inside the tool body.

[0011] A further improvement of the present invention is that: an installation block is fixedly connected to the outside of the connecting platform, and a threaded clamping block is fixedly connected to the outside of the connecting platform.

[0012] A further improvement of this utility model is that: the external thread of the threaded clamping block is fitted with a tool fastening bolt, and the internal thread of the tool base plate is connected with an adjusting bolt.

[0013] A further improvement of this utility model is that a damping block is provided on the outside of the adjusting bolt, and elastic washers are provided at both ends of the damping block.

[0014] Due to the adoption of the above technical solution, the technological progress achieved by this utility model compared to the prior art is as follows:

[0015] 1. This utility model provides a vibration-damping forming milling cutter. Under the combined action of elastic washers, adjusting bolts and damping blocks, when the workpiece is milled using this vibration-damping forming milling cutter, the generated vibration is transmitted to the damping block through the machining insert. The generated vibration can be canceled out by the damping block and elastic washers, thereby reducing the vibration of the entire tool holder, improving machining accuracy and ensuring machining quality.

[0016] 2. This utility model provides a vibration-damping milling cutter. Under the combined action of the tool fastening bolt, the threaded clamping block and the mounting block, the tool fastening bolt is screwed into the threaded clamping block through the tool mounting hole, causing the threaded clamping block to expand outward and the outer surface of the threaded clamping block to be in close contact with the inner surface of the tool slot, eliminating the gap between the tool assembly and the tool holder body and reducing the vibration generated during machining.

[0022] The present invention will be further described in detail below with reference to embodiments:

[0023] like Figure 1-4 As shown, this utility model provides a vibration-damping milling cutter, including a tool clamping assembly 1, a tool assembly 2, and a vibration-damping assembly 3. The tool clamping assembly 1 includes a tool holder body 10 and a loading / unloading groove 11. The loading / unloading groove 11 is opened on both sides of the tool holder body 10, and the loading / unloading groove 11 facilitates the loading and unloading operation of the tool clamping assembly 1 with the machine tool. A tool mounting hole 13 is opened at the bottom of the tool holder body 10, and the tool assembly 2 can be connected to the tool clamping assembly 1 through the tool mounting hole 13. A tool slot 12 is provided inside the tool mounting hole 13, and the tool assembly 2 can be locked through the tool slot 12.

[0024] The tool assembly 2 includes a tool body 20 and a connecting platform 26. The connecting platform 26 is fixedly connected to the top of the tool body 20. A threaded clamping block 23 is fixedly connected to the outside of the connecting platform 26. The tool body 20 and the tool holder body 10 can be connected through the threaded clamping block 23. The connecting platform 26 can connect the tool body 20 to the mounting block 21 and the threaded clamping block 23. A chip removal groove 29 is provided at the bottom of the tool body 20, through which waste chips generated during machining can be discharged. A machining insert 24 is threadedly fixed at the bottom of the tool body 20. During machining, the machining insert 24 directly contacts the workpiece. A insert fastening bolt 25 is provided inside the machining insert 24, and the machining insert 24 is connected to the tool body 20 through the insert fastening bolt 25. A mounting block 21 is fixedly connected to the outside of the connecting platform 26. The mounting block 21 can share the force on the threaded clamping block 23 during machining, preventing damage during machining. Excessive force can break the threaded clamping block 23, causing a safety accident. The threaded clamping block 23 has a tool fastening bolt 22 installed on its external thread. The tool fastening bolt 22 is screwed into the threaded clamping block 23 through the tool mounting hole 13, causing the threaded clamping block 23 to expand outward. This allows for a closer connection between the tool clamping assembly 1 and the tool assembly 2, eliminating the gap between the tool assembly 2 and the tool holder body 10 during installation. The tool assembly 2 can be installed into the tool holder body 10 through the mounting block 21 and the tool slot 12 inside the tool holder body 10. Then, the tool fastening bolt 22 is screwed into the threaded clamping block 23 through the tool mounting hole 13, causing the threaded clamping block 23 to expand outward. This makes the outer surface of the threaded clamping block 23 fit tightly against the inner surface of the tool slot 12, securing the tool assembly 2 and eliminating the gap between the tool assembly 2 and the tool holder body 10 during installation. This reduces vibration during machining and improves machining accuracy.

[0025] The vibration damping component 3 is installed inside the tool assembly 2. The vibration damping component 3 includes a tool base plate 34, which is fixedly installed inside the tool body 20. A washer fixing plate 33 is movably installed inside the tool body 20. An adjusting bolt 30 is threadedly connected inside the tool base plate 34. The adjusting bolt 30 is threaded to the tool base plate 34 through the thread at one end. A damping block 32 is provided outside the adjusting bolt 30. Elastic washers 31 are provided at both ends of the damping block 32. The damping block 32 and the elastic washers can be connected by the washer fixing plate 33, the adjusting bolt 30, and the tool base plate 34. The elastic washer 31 is fixed inside the tool body 20. The elastic washer 31 can absorb the vibration from the machining insert 24. When the anti-vibration forming milling cutter is used to mill the workpiece, the vibration generated by contact with the workpiece is transmitted to the damping block 32 inside the tool body 20 through the machining insert 24. Since the damping block 32 is provided with elastic washers 31 at both ends, the vibration generated during the machining process can be canceled by the damping block 32 and the elastic washer 31, so that the vibration will not continue to be transmitted backward along the tool holder body 10, thereby reducing the vibration of the entire tool holder, improving machining accuracy, and ensuring machining quality.

[0026] The working principle of this vibration-damping forming milling cutter will be explained in detail below.

[0027] like Figure 1-4 As shown, this utility model provides a vibration-damping milling cutter. During the installation of the tool assembly 2 and the tool clamping assembly 1, the tool fastening bolt 22, the threaded clamping block 23, and the mounting block 21 work together to install the tool assembly 2 into the tool holder body 10 via the tool slot 12 inside the mounting block 21. Then, the tool fastening bolt 22 is screwed into the threaded clamping block 23 through the tool mounting hole 13, causing the threaded clamping block 23 to expand outwards. This makes the outer surface of the threaded clamping block 23 tightly adhere to the inner surface of the tool slot 12, securing the tool assembly 2 and eliminating any gap between the tool assembly 2 and the tool holder body 10 during installation. This reduces vibration during machining, improves machining accuracy, and minimizes vibrations generated during machining. Vibration is mitigated by the combined action of the elastic washer 31, adjusting bolt 30, and damping block 32. The adjusting bolt 30 is threaded to the tool base plate 34, and the elastic washer 31 and damping block 32 are fixed by the washer fixing plate 33 on the top of the adjusting bolt 30. When the anti-vibration forming milling cutter is used to mill the workpiece, the vibration generated by contact with the workpiece is transmitted to the damping block 32 inside the tool body 20 through the machining insert 24. Since the damping block 32 is provided with elastic washers 31 at both ends, the vibration generated during the machining process can be canceled by the damping block 32 and the elastic washer 31, so that the vibration will not continue to be transmitted backward along the tool holder body 10, thereby reducing the vibration of the entire tool holder, improving machining accuracy, and ensuring machining quality.

[0028] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
