Description

Technical Field

[0001] This utility model relates to the field of damping and vibration reduction structure technology, specifically to a damping and vibration reduction structure for an anti-vibration milling tool holder. Background Technology

[0002] The field of damping and vibration reduction structure technology is mainly used to reduce or suppress vibration and noise, thereby improving the stability and accuracy of machining. In milling tool holders, the application of damping and vibration reduction structure technology can effectively reduce the vibration generated by the tool during high-speed rotation, reduce the impact between the tool and the workpiece, and improve machining accuracy and surface quality. Anti-vibration milling tool holders, through built-in damping materials or structures, can absorb and attenuate vibration energy, avoiding tool wear, machining errors, and reduced machining efficiency caused by vibration.

[0003] Chinese utility model patent CN211539655U discloses a tool holder with vibration damping function, which includes "when the milling cutter is clamped, the user can rotate the bolt clockwise to screw the bolt into the threaded hole, thereby installing and fixing the milling cutter, preventing the milling cutter from shaking due to the chuck loosening, thus greatly improving the machining accuracy of the milling cutter"; however, when maintaining or replacing the milling cutter, the surface of the tool holder cannot be directly operated. Instead, the operator needs to use additional disassembly and assembly tools to twist the bolt to drive it into and out of the threaded holes on both sides of the tool holder, and then remove the milling cutter. The operation process is cumbersome and laborious, and the dislodged bolt is inconvenient to store and is easy to lose, affecting the user experience and making it impractical. Utility Model Content

[0004] The purpose of this utility model is to provide a damping and vibration reduction structure for an anti-vibration milling tool holder, so as to solve the problems mentioned in the background art, which require additional disassembly and assembly tools, the operation process is cumbersome and laborious, and the loosened bolts are inconvenient to put away and are easy to be lost.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a damping and vibration reduction structure for an anti-vibration milling tool holder, comprising a mounting base, wherein the top of the mounting base is provided with a mounting hole.

[0006] The bottom of the mounting base is fitted with a damping block, the bottom of the damping block is fitted with a tool handle body, and the inside of the tool handle body has a cavity.

[0007] Several vibration damping components are installed on the top of the inner wall of the cavity, and a pad is installed at the bottom of the vibration damping components. A milling cutter holder is inserted into the bottom of the pad, and threaded holes are opened at the top of both sides of the milling cutter holder.

[0008] The bottom of both sides of the handle body is equipped with a stand, and a connecting rod is slidably connected inside the stand. A pressure ring is installed at one end of the surface of the connecting rod, and a return spring is provided on one side of the pressure ring.

[0009] A spiral groove is formed at the other end of the connecting rod surface.

[0010] The vibration damping assembly includes a pressure plate mounted on the top of the cavity inner wall, a damping rod mounted on the middle of the upper surface of the pressure plate, a support ring welded to the top of the surface of the damping rod, and a vibration damping spring provided at the bottom of the support ring.

[0011] The beneficial effects of this utility model are as follows: by pulling the handle outward or pushing it inward while simultaneously rotating it, the cutting tool can be disassembled and assembled without the use of additional tools. Furthermore, the elastic force can be used to push the spiral groove end of the connecting rod to always extend into the cavity, preventing the connecting rod from falling out of the stand. This avoids the problems of inconvenient placement and easy loss of bolts after disassembly, simplifying the disassembly and assembly process of milling tools, eliminating the need for additional tools, and allowing users to easily maintain and replace milling tools. This improves the convenience and efficiency of operation, while also avoiding the problem of easy loss associated with bolt installation, thus enhancing the user experience and the overall practicality of the machine.

[0012] To ensure that one end of the connecting rod can be precisely inserted into the threaded hole, and that the milling cutter holder can be installed and fixed by rotating the connecting rod:

[0013] Further configuration: the external dimensions of one end of the connecting rod are consistent with the internal dimensions of the threaded hole.

[0014] By adopting the above technical solution, one end of the connecting rod is aligned with the threaded hole, and the connecting rod is pushed to embed into the threaded hole. Then, the connecting rod is rotated. The spiral groove on one end of the connecting rod surface cooperates with the threaded hole. Then, the thread transmission force is used to make the spiral groove on the connecting rod surface completely screwed into the threaded hole, thereby realizing the installation and fixation of the milling tool holder.

[0015] To enable easy disengagement and screwing of the connecting rod's helical groove end from and into the threaded hole:

[0016] The link is further configured such that a handle is provided on one side of the link, and the handle is connected to the upright to form a pull-out structure.

[0017] By adopting the above technical solution, while pulling the handle outward or pushing it inward, the handle is rotated accordingly, thereby allowing the spiral groove end of the connecting rod to be disengaged from and screwed into the threaded hole, avoiding the use of additional tools.

[0018] To prevent the helical groove end of the connecting rod from slipping outwards after it comes out of the threaded hole, thus preventing it from falling out of the support frame:

[0019] The further configuration is as follows: the pressure ring forms a buffer structure with the upright frame through a reset spring.

[0020] By adopting the above technical solution, after the helical groove end of the connecting rod is disengaged from the inside of the threaded hole, the surface of the connecting rod will extend outward along the inside of the stand. At the same time, the return spring will be squeezed by the inner wall of the stand and the pressure block on both sides, resulting in contraction. Thus, after the milling tool is removed and the handle is released, the helical groove end of the connecting rod will be pushed into the cavity by the elastic force, thereby preventing the connecting rod from falling out of the stand and avoiding the problems of inconvenient placement and easy loss caused by bolt installation.

[0021] To achieve improved damping and vibration reduction by adding a sandwich layer between the mounting base and the tool holder body, as well as between the vibration damping assembly and the milling cutter:

[0022] Further configuration: the damping block is made of polymer resin, and the pad is made of rubber.

[0023] By adopting the above technical solutions, damping blocks made of polymer resin and pads made of rubber are used respectively. Neither of these materials will release toxic or harmful gases, and both can provide vibration reduction and damping effects.

[0024] The parts of the device not covered herein are the same as or can be implemented using existing technologies. Attached Figure Description

Detailed Implementation

[0030] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be described in detail below with reference to the accompanying drawings. The description in this part is only exemplary and explanatory, and should not be used to limit the scope of protection of the present invention in any way.

[0031] Please see Figures 1 to 4 A damping structure for an anti-vibration milling tool holder includes a mounting base 1, with a mounting hole 2 on the top of the mounting base 1.

[0032] The bottom of the mounting base 1 is fitted with a damping block 3, the bottom of the damping block 3 is fitted with a tool handle body 4, and the inside of the tool handle body 4 is provided with a cavity 5.

[0033] Several vibration damping components 6 are installed on the top of the inner wall of the cavity 5. A pad 7 is installed at the bottom of the vibration damping component 6. A milling cutter holder 8 is inserted into the bottom of the pad 7. Threaded holes 9 are opened at the top of both sides of the milling cutter holder 8.

[0034] The bottom ends of both sides of the handle body 4 are equipped with a stand 10. The stand 10 is slidably connected to a connecting rod 11. One end of the surface of the connecting rod 11 is equipped with a pressure ring 12. A return spring 13 is provided on one side of the pressure ring 12.

[0035] A spiral groove 14 is provided at the other end of the surface of the connecting rod 11.

[0036] The vibration damping assembly 6 includes a pressure plate 601 installed on the top of the inner wall of the cavity 5, a damping rod 602 installed in the middle of the upper surface of the pressure plate 601, a support ring 603 welded to the top of the surface of the damping rod 602, and a vibration damping spring 604 provided at the bottom of the support ring 603.

[0037] In this embodiment, as Figure 2 As shown, the external dimensions of one end of the connecting rod 11 are consistent with the internal dimensions of the threaded hole 9.

[0038] In this embodiment, as Figure 2 As shown, a handle is provided on one side of the connecting rod 11, and a pull-out structure is formed by connecting the handle and the upright 10.

[0039] In this embodiment, as Figure 2 As shown, the pressure ring 12 forms a buffer structure with the upright frame 10 through the return spring 13.

[0040] In this embodiment, as Figure 3 As shown, the damping block 3 is made of polymer resin, and the pad 7 is made of rubber.

[0041] The damping and vibration reduction structure of this vibration-resistant milling tool holder works as follows:

[0042] First, when the operator uses the milling cutter holder, align the top of the milling cutter holder 8 with the cavity 5 inside the cutter holder body 4. Then, simultaneously pull the handles on both sides of the cutter holder body 4, causing the spiral groove 14 end of the connecting rod 11 to disengage from the cavity 5. At this time, the surface of the connecting rod 11 will extend outward along the inside of the stand 10. Simultaneously, the return spring 13 will be compressed by the inner wall of the stand 10 and the pressure ring 12, resulting in contraction. Further, the milling cutter holder 8 can be pushed until the protrusion at the bottom of the pad 7 is embedded in the slot at the top of the milling cutter holder 8. At this point, the handles can be released. By utilizing the elastic force, the helical groove 14 end of the connecting rod 11 is pushed into the opening of the threaded hole 9. Then, by rotating the handle, the helical groove 14 end of the connecting rod 11 can be completely screwed into the threaded hole 9, thereby installing and fixing the milling cutter holder 8. After the milling cutter holder 8 is disassembled, the connecting rod 11 will also be affected by the elastic force, pushing the helical groove 14 end of the connecting rod 11 into the cavity 5. This prevents the connecting rod 11 from falling out of the stand 10, avoiding the problems of inconvenient placement and easy loss caused by bolt installation.
