Abstract

根据本发明的铣刀包括刀片保持件(2)，其中这些刀片保持件(2)从适于夹持到机床主轴上的承载盘(1)突出，并且各个保持件(2)通过支架(3)彼此连接。在所述保持件(2)和所述承载盘(1)之间设有臂(5)。

Description

带支架的铣刀
技术领域
本发明涉及一种铣刀，其包括从承载盘突出的刀片(插入件)保持件，该承载盘适于夹持到机床的主轴上。
背景技术
迄今已知的铣刀包括沿着工具主体的圆周布置的刀片(插入件)保持件。这些刀片保持件由出屑槽分开，所述出屑槽的主要作用是便于排屑，其次要作用是向刀片的面供应切削流体。这种设计例如可在编号：CZ278929的文献中描述的铣刀中看到。具有这种设计的铣刀通常由钢制成。它们的重量往往很大，这有助于通过减缓来自刀片的接合部的冲击来稳定它们在运转期间的转速，但也延长了使主轴达到其运转速度和使其停止所需的时间。此外，这种设计经常导致工具不平衡，并因此限制在没有损坏主轴的风险的情况下每分钟可达到的最大转数。使用这些工具的机床必须足够坚固，特别是对于可预期具有较大切削力的粗加工操作来说必须足够坚固。在需要减小铣刀主体重量的情况下，通常的解决方案是基于所识别的实际应力分布去除多余材料。这样的过程也可能损害工具内重量分布的准确性，从而导致较高速度下的平衡问题。为了减小铣刀的重量，它们的主体有时由轻合金制成，并配备有安装在钢制袋中的可更换刀片，所述钢制袋牢固地附接至所述主体。预定用于切割高强度材料的轻合金铣刀不适合粗加工操作。钛有时被用于铣刀结构中。然而，由于这种金属难以加工，因此具有钛制主体的工具是昂贵的。
发明内容
这些缺点通过包括刀片(插入件)保持件的铣刀而被消除，所述刀片保持件从承载盘突出，所述承载盘适于夹持到机床的主轴上。所述刀片保持件通过支架彼此连接。所述承载盘的这一设计使得其重量被最大程度地减小，同时因所述支架的适当配置而保持足够的刚度。
通过在所述保持件和所述承载盘之间设置臂，可以增大由所述刀片确定的周长。
通过在各个臂和支架之间设置支柱，可以提高整个结构的刚度。
通过在所述臂和所述保持件之间设置支柱，可以进一步提高刚度。
当所述保持件围绕环箍布置并且所述保持件通过加强件附接至所述环箍时，实现了刚度的额外增大，所述环箍在径向方向上或面方向上都未超过所述刀片的包络线(包络面)地突出。以这种方式构造的杆的空间格架以最小重量提供了最大刚度。
附图说明
图1中示出了使用轴测投影得到的承载盘一侧的铣刀的大体视图，其中省略了刀片；
图2中示出了可更换刀片保持件一侧的前视图；
图3中示出了承载盘一侧的另一视图；并且
图4中示出了使用轴测投影得到的刀片保持件一侧的视图。
具体实施方式
所述铣刀包括刀片(插入件)保持件2，其中保持件2从承载盘1突出，所述承载盘1适于夹持到机床的主轴上。保持件2通过支架3彼此连接。在保持件2和承载盘1之间设有臂5。在臂5和支架3之间设有支柱4。保持件2围绕环箍6布置并且通过加强件7连接至环箍6，所述环箍6未超过刀片的包络线(包络面)地突出。刀片未在附图上示出；刀片至保持件2的附接在本发明的范围之外。具有喷嘴8的管从设有工艺流体入口的承载盘1引出，喷嘴8瞄准刀片的面。所述铣刀还设有平衡附件9，所述平衡附件9包括具有可调节重量的衬套。平衡附件9补偿工具重量的不均匀分布，并且它们的设计在本发明的范围之外。
