Description

正反转切割双锯片装置
技术领域
本实用新型属于切割机领域，尤其涉及一种双锯片装置。
背景技术
现有技术中，有一类电圆锯用锯片，它只能单一方向旋转切割，由于反作用大，手持操作费力，不能切割普通钢铁等质地坚硬的材料；还有一种正反转切割机双锯片，两锯片的定位靠台阶，要求加工精度高，锯片切割过程会造成局部受热变形严重，造成在实际切割中两锯片之间往往贴合不好，而无法正常切割。
发明内容
为了克服现有的正反转切割机双锯片的加工精度要求很高、可靠性低、成本高的不足，本实用新型提供一种降低加工精度、提高可靠性、降低成本的正反转切割双锯片装置。
本实用新型解决其技术问题所采用的技术方案是：
一种正反转切割双锯片装置，包括外轴套和内轴套，所述内轴套通过轴承安装在所述外轴套上，外锯片安装在外轴套上，内锯片安装在内轴套上，所述外锯片和内锯片的装配相对面均为锥面，所述内锯片和外锯片之间的距离从外端到内侧逐渐变大。
锯片包括基体和齿端，本实用新型定义的外端为靠近齿端侧，内侧为基体侧，即靠近锯片和轴套的安装处。
进一步，所述内轴套表面设有与内锯片的安装孔对应的用于防错装的凸点；所述外轴套表面设有与外锯片的安装孔对应的用于防错装的凸点。
再进一步，所述内锯片和外锯片之间的距离由内轴套2和外轴套1的定位面高度差控制，其范围是：0.005～0.15mm。
更进一步，所述外锯片和内锯片的相对面的夹角为1～3°。
本实用新型的技术构思为：外轴套与内轴套的旋转方向相向，各带动第二锯片与第一锯片往不同方向旋转，由于两锯片均有一锥面，受热后变形均匀，切割过程中能很好调整切割机两锯片的贴合度，消除了由于切割过程中锯片发热局部变形导致的锯片失效现象。
本实用新型的有益效果：降低加工精度，低精度就可以满足要求，简化加工工艺，提高产品的可靠性，降低加工成本。
附图说明
图1是正反转切割双锯片装置的结构示意图；
图2是内外轴套的结构示意图。
具体实施方式
下面结合附图对本实用新型作进一步描述。
参照图1、图2，一种正反转切割双锯片装置，包括外轴套1和内轴套2，所述内轴套2通过轴承安装在所述外轴套1上，外锯片3安装在外轴套1上，内锯片4安装在内轴套2上，所述外锯片和内锯片的装配相对面均为锥面，所述内锯片和外锯片之间的距离从外端到内侧逐渐变大。
锯片包括基体和齿端，本实用新型定义的外端为靠近齿端侧，内侧为基体侧，即靠近锯片和轴套的安装处。
所述内轴套2表面设有与内锯片的安装孔对应的用于防错装的凸点；所述外轴套1表面设有与外锯片的安装孔对应的用于防错装的凸点。所述内轴套2和外轴套1的定位面的高度差为：0.005～0.15mm。所述外锯片和内锯片的相对面的夹角为1～3°。
由于两锯片均有一锥面，受热后变形均匀，切割过程中能很好调整切割机两锯片的贴合度，消除了由于切割过程中锯片发热局部变形导致的锯片失效现象。本实用新型的有益效果是降低了加工精度，低精度就可以满足要求，简化加工工艺，提高产品的可靠性，降低加工成本。
由于两锯片均有一锥面，两锯片的间隙在锯齿的地方最窄，其余的地方较宽。在操作过程中，只需要控制两锯片锯齿间的间隙，控制容易，精度要求低。两锯片的间隙由由内轴套2和外轴套1的定位面高度差控制，其间隙在0.005-0.15mm。
内外轴套表面均有凸点，与锯片的孔相对应，具有防错装功能。
