[0002] A vibration-damping thread end mill typically consists of a vibration-damping shank and a thread end mill body. The vibration-damping shank contains heavy metal, and a liquid damping agent shell is fixedly connected to its side surface. The shell contains liquid damping agent, which enables stable thread machining.
[0003] Existing shock-absorbing thread end mills can machine threads at high speeds during use, but they usually need to be disassembled and stored when not in use. However, they do not have a protective structure. If they fall during disassembly and movement, the cutting edge of the end mill can be easily damaged, making it unstable for reuse and affecting the quality of thread machining. Therefore, we propose a stable shock-absorbing thread end mill. Utility Model Content

[0027] The embodiments of this utility model will be further described below with reference to the accompanying drawings.
[0028] Example:
[0029] like Figures 1-5 As shown, a stable and shock-absorbing thread milling cutter includes a shank 1, a milling cutter processing part 2 fixedly connected to the bottom end of the shank 1, a fixed positioning mechanism 3 fixedly sleeved on the outer surface of the shank 1, a movable protective mechanism 4 sleeved on the outer bottom end of the fixed positioning mechanism 3, and a connecting reinforcement mechanism 5 fixedly provided on the upper part of the outer surface of the movable protective mechanism 4.
[0030] The working principle of the above technical solution is as follows:
[0031] During use, the movable protective mechanism 4 can be fitted onto the outer surface of the milling cutter machining part 2, and the top of the movable protective mechanism 4 can be fitted onto the outer surface of the bottom end of the fixed positioning mechanism 3 and rotated to achieve initial connection and fixation. Then, the connecting reinforcement mechanism 5 is adjusted to connect and fix the connecting reinforcement mechanism 5 and the fixed positioning mechanism 3, so that the movable protective mechanism 4 can stably provide protection for the milling cutter machining part 2, and the operation is convenient.
[0032] In another embodiment, such as Figure 2 and Figure 4 As shown, the fixed positioning mechanism 3 includes a fixed collar 31, a fixed limiting ring 32 symmetrically provided at the top of the fixed collar 31, a fixed connecting rod 33 symmetrically provided at the bottom of the fixed collar 31, a connecting base 34 fixedly connected to the bottom of the fixed connecting rod 33, and an arc-shaped groove 35 provided at the bottom of the connecting base 34.
[0033] The top of the movable protective mechanism 4 can be fitted onto the outer surface of the connecting base 34 and the fixed connecting rod 33 and rotated to form a connection, so that the movable protective mechanism 4 can stably protect the milling cutter machining part 2 and is easy to operate.
[0034] In another embodiment, such as Figure 3 As shown, the active protective mechanism 4 includes a connecting protective sleeve 41. A curved guide groove 42 is symmetrically provided on the top of the connecting protective sleeve 41. A fixing slot 43 is symmetrically provided on the top of the connecting protective sleeve 41. The fixing slot 43 is located at one end of the curved guide groove 42. A fixing guide limiting groove 44 is provided inside the connecting protective sleeve 41. A fixing installation cavity 45 is symmetrically provided inside the connecting protective sleeve 41. A first force-bearing spring 46 is fixedly connected to the bottom inner side of the fixing installation cavity 45. A force-bearing installation plate 47 is fixedly connected to the top of the first force-bearing spring 46. A fixing connecting block 48 is fixedly connected to the middle of the top of the force-bearing installation plate 47. A curved locking block 49 is fixedly connected to the top of the fixing connecting block 48. A transparent observation protective block 410 is symmetrically provided inside the lower part of the connecting protective sleeve 41.
[0035] The connecting protective sleeve 41 is positioned on the outer surface of the fixed connecting rod 33 and the connecting base 34 under the action of the fixed slot 43, so that the connecting base 34 is inside the fixed guide limiting groove 44. Then, the connecting protective sleeve 41 is rotated, so that the fixed connecting rod 33 can move inside the arc-shaped guide groove 42, and the connecting base 34 can move inside the fixed guide limiting groove 44. The bottom end of the fixed connecting rod 33 presses against the arc-shaped locking block 49, so that the arc-shaped locking block 49... Moving downwards causes the force-bearing mounting plate 47 to move, compressing the first force-bearing spring 46. When the connecting base 34 moves to the top of the arc-shaped locking block 49, the first force-bearing spring 46 can push the force-bearing mounting plate 47, the fixed connecting block 48, and the arc-shaped locking block 49 upwards, so that the arc-shaped locking block 49 can be locked into the inner side of the arc-shaped groove 35, thereby limiting the connection and allowing the connecting protective sleeve 41 to be stably fitted on the outer surface of the milling cutter machining part 2, providing protection for the milling cutter machining part 2 and making operation convenient.
[0036] In another embodiment, such as Figure 3 As shown, the edge of the force-bearing mounting plate 47 slides and fits against the inner side of the fixed mounting cavity 45, and the outer surface of the arc-shaped block 49 fits against the inner side of the arc-shaped groove 35.
[0037] The force-bearing mounting plate 47 can move stably inside the fixed mounting cavity 45, while the arc-shaped locking block 49 can be stably locked inside the arc-shaped groove 35, making operation convenient.
[0038] In another embodiment, such as Figure 3 and Figure 4 As shown, the edge of the connecting chassis 34 slides and fits against the inner side of the fixing slot 43 and the fixing guide limiting groove 44, and the outer side of the surface of the fixing connecting rod 33 fits against the inner side of the arc-shaped guide groove 42.
[0039] The fixed connecting rod 33 can move inside the arc-shaped guide groove 42, and the connecting base 34 can move inside the fixed guide limiting groove 44, making operation convenient.
[0040] In another embodiment, such as Figure 5 As shown, the connecting and reinforcing mechanism 5 includes a fixed sleeve block 51, a movable connecting rod 52 is movably connected inside the fixed sleeve block 51, a force-bearing base 53 is fixedly connected to the bottom end of the movable connecting rod 52, a second force-bearing spring 54 is movably connected between the top end of the force-bearing base 53 and the inner top end of the fixed sleeve block 51, a connecting top plate 55 is fixedly connected to the top end of the movable connecting rod 52, and a connecting insert block 56 is fixedly connected to the bottom end of the connecting top plate 55 away from the movable connecting rod 52.
[0041] After the connecting protective sleeve 41 is installed, the connecting top plate 55 is pulled first, causing the connecting plug 56, the movable connecting rod 52, and the force-bearing base 53 to move, compressing the second force spring 54, so that the connecting top plate 55 and the connecting plug 56 can be positioned above the fixed limit ring 32. Then, the connecting top plate 55 is deflected, causing the movable connecting rod 52 and the force-bearing base 53 to rotate, and at the same time, the connecting plug 56 is deflected, so that the connecting plug 56 can be positioned directly above the fixed limit ring 32. Then, the connecting top plate 55 is released, and under the action of the second force spring 54, the force-bearing base 53 moves and resets the movable connecting rod 52, the connecting top plate 55, and the connecting plug 56, so that the connecting plug 56 can be inserted into the inner side of the fixed limit ring 32, thereby limiting the connection. The operation is convenient.
[0042] In another embodiment, such as Figure 4 As shown, the outer surface of the connecting plug 56 slides and fits against the inner surface of the fixing limiting ring 32, and the bottom of the connecting top plate 55 fits against the top of the fixing limiting ring 32.
[0043] The connecting plug 56 can be stably inserted into the inner side of the fixed limiting ring 32, and the connecting top plate 55 can stably press down on the fixed limiting ring 32, thereby making a stable connection between the movable protective mechanism 4 and the fixed positioning mechanism 3, which is easy to operate.
[0044] The working principle of this utility model is as follows: During use, the connecting protective sleeve 41 is moved so that it can be fitted onto the outer surface of the fixed connecting rod 33 and the connecting base 34 under the action of the fixed slot 43. Then, the connecting protective sleeve 41 is rotated, and under the action of the arc-shaped guide groove 42 and the fixed guide limiting groove 44, it can deflect and move on the outer surface of the fixed connecting rod 33 and the connecting base 34. At the same time, the bottom end of the fixed connecting rod 33 squeezes the arc-shaped locking block 49, causing the arc-shaped locking block 49 to move downward, driving the force-bearing mounting plate 47 to move, compressing the first force-bearing spring 46. When the connecting base 34 moves to the top of the arc-shaped locking block 49, the first force-bearing spring 46 can push the force-bearing mounting plate 47, the fixed connecting block 48 and the arc-shaped locking block 49 upward, so that the arc-shaped locking block 49 can be locked into the inner side of the arc-shaped groove 35, thereby limiting the connection and ensuring that the connecting protective sleeve 41 can be stably positioned. The protective sleeve 41 is fitted onto the outer surface of the milling cutter machining section 2 to provide protection for the milling cutter machining section 2. After the protective sleeve 41 is installed, the connecting top plate 55 is pulled, which moves the connecting plug 56, the movable connecting rod 52, and the force-bearing base 53, compressing the second force-bearing spring 54 so that the connecting top plate 55 and the connecting plug 56 are above the fixed limit ring 32. Then, the connecting top plate 55 is deflected, which makes the movable connecting rod 52 and the force-bearing base 53 rotate. At the same time, the connecting plug 56 is deflected so that the connecting plug 56 is directly above the fixed limit ring 32. Then, the connecting top plate 55 is released. Under the action of the second force-bearing spring 54, the force-bearing base 53 moves and resets the movable connecting rod 52, the connecting top plate 55, and the connecting plug 56, so that the connecting plug 56 can be inserted into the inner side of the fixed limit ring 32, thereby achieving connection limitation. The overall structure is simple and the operation is convenient and quick.
[0045] The above embodiments merely illustrate specific implementations of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model.
