Abstract
Description
Technical Field
[0001] This application relates to the field of reamer technology, and more particularly to a reamer that is easy to disassemble. Background Technology
[0002] In the field of machining, reamers are an extremely important tool used to finish drilled workpieces, thereby improving the dimensional accuracy and surface finish of the holes.
[0003] However, the disassembly process of existing reamers is often cumbersome and time-consuming, especially when frequent reamer replacement or maintenance is required. Moreover, the tool is deformed due to blade wear and spindle runout, resulting in low cutting accuracy and reduced reamer life. Utility Model Content
[0004] In view of the above problems, this application provides a reamer that is easy to disassemble, in order to solve the problem that the disassembly process of existing reamers is often cumbersome and consumes a lot of time and labor costs, especially when the reamer needs to be replaced or maintained frequently. Moreover, the tool is deformed due to the wear of the cutting edge and the runout of the spindle during use, resulting in low cutting accuracy.
[0005] This application provides a reamer that is easy to disassemble. The reamer design includes a handle, an internally threaded blade connected to the handle, the blade including a disassembly mechanism, and an anti-vibration mechanism on the outer surface of the handle.
[0006] In some embodiments, a connecting hole is provided in the middle of the handle, and a torsion bar is fixedly connected to the inner wall surface of the connecting hole, passing through the interior of the handle.
[0007] In some embodiments, a slot is provided at the bottom of the handle, a retainer is engaged inside the slot, and a threaded rod is fixedly installed at the bottom of the retainer. The outer surface of the threaded rod is connected to the internal thread of the cutter head.
[0008] In some embodiments, the disassembly mechanism includes a mounting base installed at the bottom of the cutter head, and a threaded rod II is fixedly connected to the upper surface of the mounting base, the outer surface of the threaded rod II being connected to the internal threads of the cutter head.
[0009] In some embodiments, a second slot is formed on the outer surface of the cutter head, a locking block is engaged inside the second slot, and a blade is fixedly mounted on one side of the locking block.
[0010] In some embodiments, the anti-vibration mechanism includes a protective plate disposed on the outer surface of the handle, a damping spring fixedly mounted on the inner surface of the protective plate, and a damping pad fixedly mounted on the surface of the damping spring.
[0011] In some embodiments, a buffer block is fixedly installed on the surface of the first damping pad, and a second damping pad is fixedly installed on one side surface of the buffer block. One side surface of the second damping pad is fixedly connected to the outer surface of the tool holder.
[0012] The above scheme involves sliding the locking block along the surface of the second slot to engage the blade, thereby installing it on the outside of the cutter head. Rotating the mounting base then connects the threaded rod to the internal threads of the cutter head, allowing the mounting base to be installed at the bottom of the cutter head, creating a limit and preventing the blade from falling off. The locking mechanism facilitates disassembly, saving manpower and time, and improving production efficiency. By incorporating a second damping pad, when the cutter handle vibrates during drilling, it contacts the damping pad, absorbing and gradually transmitting the vibration. The cooperation between the first damping pad and the buffer block further compresses and absorbs the vibration. Simultaneously, the damping spring utilizes its elasticity to weaken the vibration, and the protective plate further protects the cutter handle, extending its service life and preventing deformation, thus improving the reamer's working efficiency.

[0025] To facilitate understanding of the technical solutions in the embodiments of this application, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings.
[0026] First, it should be noted that the reamer in this application embodiment can be applied to the mechanical field or to other equipment, and this application does not limit it.
[0027] This application provides a reamer that is easy to disassemble. Figure 1 This is a perspective view of the reamer in some embodiments of this application. Figure 2 This is an exploded view of the tool holder in some embodiments of this application. For example... Figure 1 , Figure 2 As shown, the easily disassembled reamer design includes a handle 1, a cutter head 2 internally threadedly connected to the handle 1, a disassembly mechanism 3 included in the cutter head 2, an anti-vibration mechanism 4 provided on the outer surface of the handle 1, a connecting hole 11 in the middle of the handle 1, a torsion bar 12 fixedly connected to the inner wall surface of the connecting hole 11, passing through the interior of the handle 1, a slot 13 at the bottom of the handle 1, a retainer 14 engaged inside the slot 13, a threaded rod 15 fixedly installed at the bottom of the retainer 14, and the outer surface of the threaded rod 15 connected to the internal thread of the cutter head 2.
[0028] In the technical solution of this application embodiment, since the torsion bar 12 is fixedly connected inside the connecting hole 11 and passes through the inside of the tool holder 1, the card seat 14 and the card slot 13 are then snapped together. After holding both ends of the torsion bar 12 and rotating it clockwise, the threaded rod 15 can be threadedly connected to the inside of the tool head 2 for easy installation. 。
[0029] According to other embodiments of this application, such as Figure 3As shown, the disassembly mechanism 3 includes a mounting base 31 installed at the bottom of the cutter head 2. A threaded rod 32 is fixedly connected to the upper surface of the mounting base 31. The outer surface of the threaded rod 32 is threadedly connected to the inside of the cutter head 2. A slot 33 is opened on the outer surface of the cutter head 2. A locking block 34 is locked inside the slot 33. A blade 35 is fixedly installed on one side of the locking block 34.
[0030] In this embodiment, the blade 35 is installed on the outside of the cutter head 2 by sliding the locking block 34 along the surface of the locking groove 33. Then, by rotating the mounting base 31, the threaded rod 32 is connected to the internal thread of the cutter head 2, and the mounting base 31 is installed at the bottom of the cutter head 2 to form a limit and prevent the blade 35 from falling off. The locking mechanism facilitates disassembly.
[0031] According to other embodiments of this application, such as Figure 4 As shown, the anti-vibration mechanism 4 includes a protective plate 41 disposed on the outer surface of the tool holder 1. A damping spring 42 is fixedly installed on the inner surface of the protective plate 41. A damping pad 43 is fixedly installed on the surface of the damping spring 42. A buffer block 44 is fixedly installed on the surface of the damping pad 43. A second damping pad 45 is fixedly installed on one side surface of the buffer block 44. One side surface of the second damping pad 45 is fixedly connected to the outer surface of the tool holder 1.
[0032] In the technical solution of this embodiment, by setting a second damping pad 45, when the tool holder 1 vibrates due to drilling, it comes into contact with the second damping pad 45, absorbing and gradually transmitting the vibration. Through the cooperation between the first damping pad 43 and the buffer block 44, the generated vibration is squeezed and absorbed. At the same time, the damping spring 42 is used to weaken the vibration by utilizing its elasticity, and the tool holder 1 is protected by the protective plate 41, which helps to improve its service life and prevent deformation.
[0033] The working principle of this easy-to-disassemble reamer design will be explained in detail below.
[0034] like Figure 1As shown in Figure 4, firstly, the card holder 14 and the card slot 13 are snapped together. Then, by holding both ends of the torsion bar 12, it is rotated clockwise so that the threaded rod 15 can be threadedly connected to the inside of the cutter head 2 for installation. At the same time, the card block 34 slides along the surface of the card slot 33 to snap together, thereby installing the blade 35 on the outside of the cutter head 2. Then, by rotating the mounting base 31, the threaded rod 32 is threadedly connected to the inside of the cutter head 2, thereby installing the mounting base 31 at the bottom of the cutter head 2 to form a limit and prevent the blade 35 from falling off. Then, by setting the damping pad 45, when the tool handle 1 vibrates due to drilling, it comes into contact with the damping pad 45, absorbing and gradually transmitting the vibration. Through the cooperation between the damping pad 43 and the buffer block 44, the generated vibration is squeezed and absorbed. At the same time, the damping spring 42 is used to weaken the vibration by utilizing its elasticity, and the protective plate 41 protects the tool handle 1, which helps to improve its service life.
