霸刀分享-刀柄结构组成
数控刀柄主要由刀柄本体、锁紧机构、定位系统三部分核心结构组成，部分新型刀柄还包含辅助功能模块（如冷却、减振），整体需满足刚性、精度与适配性要求。
1. 刀柄本体
刀柄本体是刀柄的核心部分，用于承载刀具并连接机床。其主体结构常用材质包括碳素钢、合金钢，以确保刀柄的刚性和耐用性。
2. 锁紧机构
锁紧机构利用撞块与弹簧片配合，实现刀柄的稳固锁紧。此外，通过拉杆、油缸及弹簧等部件，实现刀柄的自动夹紧与松开。
3. 定位系统
定位系统包括BIGPlus系统，主轴与刀柄三面贴合，无间隙。此外，7:24锥度刀柄，配合紧密，提高加工精度与刚性。
4. 锥度配合系统
多数数控刀柄采用7:24圆锥工具刀柄，这种锥度配合系统能够确保刀柄与机床主轴之间的紧密配合，提高加工精度与刚性。
以上是数控刀柄的主要结构组成，这些组成部分共同确保了刀具在加工过程中的稳定性和精度。
The structural composition of the CNC tool holder
The CNC tool holder mainly consists of three core structures: the tool holder body, the locking mechanism, and the positioning system. Some new types of tool holders also include auxiliary function modules (such as cooling and vibration reduction). The overall structure needs to meet the requirements of rigidity, accuracy, and adaptability.
1. CNC tool holder body
The body of the CNC tool holder is the core part of the tool holder, used to support the tool and connect the machine tool. The common materials for its main structure include carbon steel and alloy steel to ensure the rigidity and durability of the tool holder.
2. Locking mechanism
The locking mechanism uses the coordination of the impact block and the spring plate to achieve a stable locking of the tool holder. In addition, the automatic clamping and release of the tool holder are achieved through components such as the pull rod, oil cylinder and spring.
3. Positioning system
The positioning system includes the BIGPlus system, where the spindle and the tool holder are in three-sided contact without any gap. In addition, the 7:24 taper tool holder fits tightly, enhancing the machining accuracy and rigidity.
4. Taper fit system
Most CNC tool holders use 7:24 conical tool holders. This conical fit system can ensure a tight fit between the tool holder and the machine tool spindle, improving machining accuracy and rigidity.
The above are the main structural components of the CNC tool holder. These components jointly ensure the stability and accuracy of the tool during the machining process.
