[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-4 This utility model provides a technical solution: a follow-up tool magazine protection mechanism for CNC machining, including a fixed shell 1 and a limiting component 2. The outer wall of the limiting component 2 is slidably connected to the outer wall of the fixed shell 1. The limiting component 2 is used to change the position of the fixed shell 1 by sliding. A protective component 3 is fixedly connected to the outer wall of the fixed shell 1. The protective component 3 includes a baffle 31, and a top spring 32 is fixedly connected to the outer wall of the baffle 31. The top springs 32 are arranged in a circular array along the central axis of the baffle 31. A resistance rod 33 is fixedly connected, and the resistance rod 33 is arranged in a circular array along the central axis of the baffle 31. The end of the top spring 32 away from the baffle 31 is fixedly connected to the outer wall of the fixed shell 1. The outer wall of the fixed shell 1 is fixedly connected to the outer wall of the resistance rod 33. One end of the top spring 32 is fixed to the outer wall of the baffle 31, and the other end is fixed to the outer wall of the fixed shell 1. When chips, cutting fluid and other debris splash around the tool magazine, the baffle 31 will be impacted. At this time, the top spring 32 will undergo elastic deformation to absorb part of the impact force and play a buffering role.

[0024] The limiting component 2 includes a sliding shell 21, a protective shell 23 fixedly connected to the outer wall of the sliding shell 21, a pin 24 slidably connected to the inner wall of the top of the protective shell 23, a sliding block 26 slidably connected to the inner wall of the protective shell 23, and the sliding blocks 26 are arranged in a circular array along the central axis of the protective shell 23. A post 22 is fixedly connected to the inner wall of the sliding shell 21, and the post 22 is arranged in a circular array along the central axis of the sliding shell 21. A locking bolt 27 is rotatably connected to the inner wall of the sliding block 26. The pin 24 is slidably connected to the inner wall of the top of the protective shell 23, and a tension spring 25 is fixedly connected to its outer wall. The other end of the tension spring 25 is fixed to the outer wall of the protective shell 23. When it is necessary to adjust the position of the fixed shell 1, the operator can pull the pin 24 upward to pull the pin 24 out from the inner wall of the top of the fixed shell 1. At this time, the fixed shell 1 can slide freely inside the sliding shell 21.

[0025] The outer wall of the insert 22 is slidably connected to the inner wall of the fixed shell 1. The inner wall of the top of the fixed shell 1 is inserted into the bottom of the pin 24. A tension spring 25 is fixedly connected to the outer wall of the pin 24. The end of the tension spring 25 away from the pin 24 is fixedly connected to the outer wall of the protective shell 23. The outer wall of the protective shell 23 is slidably connected to the outer wall of the fixed shell 1. The outer wall of the fixed shell 1 is slidably connected to the outer wall of the sliding shell 21.

[0026] The protective mechanism mainly consists of a fixed shell 1, a limiting component 2, and a protective component 3. The fixed shell 1 serves as the basic structure, providing an installation platform for the protective component 3. It also works with the limiting component 2 to adjust the position. The limiting component 2 changes the position of the fixed shell 1 by sliding to adapt to the length and movement of the tool magazine. The protective component 3 directly protects the tool magazine and prevents foreign objects from entering it.

[0027] The protective component 3 consists of a baffle 31, a top spring 32, and a resistance rod 33. The baffle 31 is the component that directly provides protection. The top spring 32 and the resistance rod 33 are fixedly connected to its outer wall, and the top spring 32 and the resistance rod 33 are arranged in a circular array along the central axis of the baffle 31.

[0028] One end of the top spring 32 is fixed to the outer wall of the baffle 31, and the other end is fixed to the outer wall of the fixed housing 1. When chips, cutting fluid and other debris splash around the tool magazine, the baffle 31 will be impacted. At this time, the top spring 32 will undergo elastic deformation to absorb part of the impact force and play a buffering role to prevent the baffle 31 from being damaged by excessive impact. At the same time, the elastic restoring force of the top spring 32 can make the baffle 31 quickly return to its original position after being impacted, maintaining the protective effect.

[0029] One end of the resistance rod 33 is fixed to the outer wall of the baffle 31, and the other end is fixed to the outer wall of the fixed shell 1. The resistance rod 33 can extend and retract within a certain range to provide support and guidance for the baffle 31. When the baffle 31 is impacted, the resistance rod 33 can extend and retract with the movement of the baffle 31 to ensure the smooth movement of the baffle 31. When the top spring 32 recovers its elastic deformation, it helps the baffle 31 return to its original position. Through the synergistic effect of the top spring 32 and the resistance rod 33, the protective component 3 can block debris and protect the tool magazine.

[0030] The limiting component 2 consists of a sliding shell 21, a pin 22, a protective shell 23, a pin 24, a tension spring 25, a sliding block 26, and a locking bolt 27. The outer wall of the sliding shell 21 is slidably connected to the outer wall of the fixed shell 1, and the inner wall of the sliding shell 21 is fixedly connected to the pin 22. The pins 22 are arranged in a circular array along the central axis of the sliding shell 21. The outer wall of the pin 22 is slidably connected to the inner wall of the fixed shell 1, so that the fixed shell 1 can slide in the sliding shell 21 along the direction of the pin 22, thereby realizing the adjustment of the position of the fixed shell 1.

[0031] The protective shell 23 is fixedly connected to the outer wall of the sliding shell 21, serving to protect the internal components. The pin 24 is slidably connected to the inner wall of the top of the protective shell 23, and a tension spring 25 is fixedly connected to its outer wall. The other end of the tension spring 25 is fixed to the outer wall of the protective shell 23. When it is necessary to adjust the position of the fixed shell 1, the operator can pull the pin 24 upward to pull the pin 24 out from the inner wall of the top of the fixed shell 1. At this time, the fixed shell 1 can slide freely in the sliding shell 21. After adjusting to the appropriate position, the pin 24 is released. Under the action of the tension spring 25, the pin 24 will re-insert into the inner wall of the top of the fixed shell 1, fixing the fixed shell 1 in the corresponding position.

[0032] The sliding blocks 26 are arranged in a circular array along the central axis of the protective shell 23 and are slidably connected to the inner wall of the protective shell 23. The inner wall of the sliding blocks 26 is rotatably connected to the locking bolts 27. When the fixed shell 1 is adjusted to a suitable position and fixed by the pins 24, the operator can rotate the locking bolts 27 to make the end of the locking bolts 27 in close contact with the outer wall of the fixed shell 1, further enhancing the fixing effect of the fixed shell 1 and preventing it from shifting due to vibration or other reasons during CNC machining.

[0033] During CNC machining, the baffle 31 of the protective component 3 protects the tool magazine under the action of the top spring 32 and the resistance rod 33. When chips, cutting fluid and other debris splash, the baffle 31 blocks the debris, the top spring 32 absorbs the impact force, and the resistance rod 33 assists the movement of the baffle 31 and maintains its stability, preventing debris from entering the tool magazine.

[0034] When the position or movement of the tool magazine changes and the position of the protective mechanism needs to be adjusted, the operator pulls the pin 24 upward to remove it from the inner wall of the top of the fixed housing 1. At this time, the fixed housing 1 can slide freely in the sliding housing 21. According to the movement of the tool magazine and the length of the tool, the fixed housing 1 is adjusted to a suitable position. Then the pin 24 is released and the tension spring 25 re-inserts the pin 24 into the inner wall of the top of the fixed housing 1.

[0035] After CNC machining is completed, the operator can maintain and inspect the protective mechanism, check whether the top spring 32 and resistance rod 33 are damaged, and replace them in time if they are damaged; check whether the connections of components such as pin 24, tension spring 25, sliding block 26 and locking bolt 27 are loose, and tighten them in time if they are loose to ensure the normal operation of the protective mechanism.
