Description

一种加工内外螺纹的车床用刀架 技术领域
本发明属于车床刀架技术领域，具体地说是涉及一种加工内外螺纹的车床用刀架。
背景技术
车床在加工螺纹时，管材件一般被车床的卡爪夹住带动旋转，刀具由进给模块控制走刀量来完成车螺纹。当加工的管材件体积较大时，一些车床就会保持管材件固定不动，利用固定于车床主轴旋转的刀具模块进行车螺纹；但面对更大体积的管材时，一般的刀架即使处于极限调节位置时仍无法满足加工需要，这就急需一种特殊刀架，用以加工大尺寸管材件的螺纹。
发明内容

进一步的，所述刀具固定架包括刀具固定端口、设于刀具固定端口左端面中央位置的调节轴和于调节轴左端面同心设置的过渡调节轴；所述过渡调节轴的长度与调节底座右端面相匹配，所述刀具固定端口通过设置的多组固定螺栓与刀具匹配固定。分段处理的调节轴和过渡调节轴便于对刀具固定架整体的限位；通过作用于调节轴的多组调节螺栓，保证刀具固定架整体的定位。
进一步的，所述支撑模块上端面设有连接调节轴套的过渡圆台，过渡圆台与调节轴套同心并设有与过渡调节轴匹配的通孔；所述支撑模块左端面设有纵向的滑槽，滑槽底部设有与垂直距离调节组件内部结构匹配的齿槽。过渡圆台起到限位作用，避免过渡调节轴与调节底座相干涉。
进一步的，所述调节底座的长度远大于支撑模块的长度，调节底座右端面设有与滑槽匹配的滑台，滑台的长度与调节底座的长度相匹配；所述滑台的中部设有与垂直距离调节组件内部结构匹配的腰型长槽。远大于支撑模块长度的调节底座保证了支撑模块足够的位移量，腰型长槽给垂直距离调节组件内部结 构与支撑模块的联动提供了空间。
