Abstract

一种车刀，具有一刀头部（20）、一刀颈部（30）及一刀杆部（40），车刀内贯设有一通道（50），该通道贯通该刀头部、该刀颈部及该刀杆部，该通道用来灌注冷却液，而冷却液是自该刀杆部灌入，该刀头部是用来对工件进行加工，而该刀颈部具有一刀颈径长（34），该刀杆部具有一刀杆径长（42），该刀颈径长大于该刀杆径长，在冷却液自该通道渗出时，冷却液会沿着该刀杆部的外周面流至该刀颈部，由于该刀颈部的该刀颈径长大于该刀杆部的该刀杆径长，使渗出的冷却液会被该刀颈部阻挡，进而防止渗出的冷却液流至该刀头部并回流至该刀柄部，不仅能够达成防止该刀头部锈蚀的缺陷，更能够延长该车刀的使用寿命。

Description

车刀 技术领域
本发明关于一种车刀，特别是关于对车刀的结构进行改良。
背景技术
一般车床加工技术应用各式刀具对各式加工物进行加工。在加工过程中，因为刀具与加工物接触及摩擦而容易产生高热，若不能适当的降温，对于刀具及加工物都容易产生损害，不仅造成良品率降低，更增加刀具毁损的机率；因此，必须在加工过程中利用冷却液进行冷却。
目前现有技术中一种能够填充冷却液的车刀结构，请参阅图1及图2，车刀10具有衔接的一刀杆11及一刀头12，而该刀杆11内穿设有一通道13，该通道13的其中一端贯穿该刀杆11连接该刀头12的另一端，而该通道13的另一端则连通至该刀头12，该通道13用来流入冷却液，通过冷却液使该刀杆11及该刀头12降温。
然而，冷却液从该通道13的其中一端注入时，会有部分冷却液从该通道13渗出，渗出的冷却液沿着该刀杆11的外周面滴至该刀头12，导致该车刀10的刀头12容易锈蚀，进而降低该车刀10的使用寿命。
有鉴于此，确有必要提供一种车刀10，以防止冷却液从该通道13渗出。
发明内容
本发明的目的在于，防止冷却液从车刀的通道渗出，进而防止冷却液造成刀头锈蚀的缺陷。
为达成前述目的，本发明为一种车刀，包含：
一刀头部；
一刀颈部，具有一连接面及一阻挡面，该连接面连接该刀头部，而该刀颈部位于该阻挡面上具有一刀颈径长；以及
一刀杆部，连接该阻挡面，该刀杆部具有一刀杆径长，且该刀杆径长小于该刀颈径长，使该刀颈部及该刀杆部之间夹设有一阻挡角度。
在一较佳实例中，该刀头部具有一第一外周面，该连接面与该第一外 周面之间夹设有一钝角。
在一较佳实例中，该刀颈部另具有一延伸面，该延伸面的其中一端连接该连接面，该延伸面的另一端连接该阻挡面。
在一较佳实例中，该刀杆部具有一第二外周面，该第二外周面连接该阻挡面，且该阻挡角度为直角。
在一较佳实例中，该刀头部、该刀颈部及该刀杆部是依次连接，且该车刀具有沿着该延伸方向贯穿的一通道，该通道贯通该刀头部、该刀颈部及该刀杆部，且该通道的二端沿着该延伸方向开放。
由于该刀颈部的该刀颈径长大于该刀杆径长，使冷却液在注入该通道并渗漏时，能够防止渗出的冷却液流至该刀头部，不仅能够达成防止该刀头部锈蚀的缺陷，更能够延长该车刀的使用寿命。
附图说明
图1为现有技术的车刀的左视图。
图2为现有技术的车刀的剖面图。
图3为本发明在一较佳实施例中的左视图。
图4为本发明于一较佳实施例中的剖面图。
具体实施方式
请参阅图3及图4，本发明为一种车刀，包含：
一刀头部20，沿着一延伸方向X延伸，该刀头部20具有一第一外周面21，该第一外周面21为该刀头部20的周面，该刀头部20用来对工件进行加工作业；
一刀颈部30，具有一连接面31、一阻挡面32及一延伸面33，该连接面31的其中一端连接该刀头部20，该连接面31的另一端连接该延伸面33，该连接面31与该第一外周面21之间夹设有一钝角θ1，使该连接面31呈倾斜，而该延伸面33沿着该延伸方向X延伸，且该延伸面33的其中一端连接该连接面31，该延伸面33的另一端连接该阻挡面32，而该刀颈部30位于该阻挡面32上具有一刀颈径长34；以及
一刀杆部40，具有一第二外周面41，该第二外周面41连接该阻挡面 32，该刀杆部40具有一刀杆径长42，且该刀杆径长42小于该刀颈径长34，使该刀颈部30及该刀杆部40之间夹设有一阻挡角度θ2，在本实施例中该阻挡角度θ2为直角。
由此，该刀头部20、该刀颈部30及该刀杆部40是依次连接，且该车刀具有沿着该延伸方向X贯穿的一通道50，该通道50贯通该刀头部20、该刀颈部30及该刀杆部40，且该通道50的二端沿着该延伸方向X开放。
以上为本发明的结构组合状态及其连接关系，本发明的使用方式如下所述：
请参阅图3及图4，在使用本发明车刀时，该刀头部20对工件进行加工，并自该刀杆部40朝该通道50灌注冷却液，通过冷却液降低该车刀整体的温度，而冷却液在灌注的过程中可能造成渗漏，渗漏的冷却液沿着该刀杆部40的该第二外周面41流动，流至该刀颈部30后，由于该刀颈部30的该刀颈径长34大于该刀杆部40的该刀杆径长42，使冷却液被该刀颈部30的该阻挡面32阻挡，进而防止冷却液渗流至该刀头部20。
通过该刀颈部30的该刀颈径长34大于该刀杆径长42，使冷却液在注入该通道50并渗漏时，能够防止渗出的冷却液流至该刀头部20，不仅能够达成防止该刀头部20锈蚀的缺陷，更能够延长该车刀的使用寿命。
