Abstract

本实用新型涉及一种用于铣削内腔的刀具,包括一个杆铣刀,其所述的杆铣刀的基体前端为梯形,梯形沿轴向长度为18-22mm,锥角a为13-16°。本实用新型不需要钳工打磨接平,外表美观大方;去掉一道打磨工序;降低了生产成本,提高了加工效率;无粉尘产生,改善了生产环境。

Description

用于铣削内腔的刀具
技术领域
本实用新型涉及一种刀具,具体涉及用于铣削内腔的刀具。 
背景技术
在加工深孔零件时,由于锻造和收口工序的技术限制,使内腔无法保证设计要求。造成这种原因主要是锻造毛坯内腔不规则。内腔锻造时有拔模斜度,收口时多余的金属向内移动。 
为解决此问题,现有的做法是由机加保证,但由于刀具不合适,造成一个3~8mm的台阶,这个台阶再由钳工去接平,工作量大,效率低,工作环境粉尘多,环境污染严重。 
发明内容
本实用新型的目的在于提供一种不需要钳工打磨接平,外表美观,无环境污染的用于铣削内腔的刀具。 
本实用新型包括一个杆铣刀,其特点在于:所述的杆铣刀的基体前端为梯形,梯形沿轴向长度为18-22mm,锥角a为13-16°。 
本实用新型不需要钳工打磨接平,外表美观大方;去掉一道打磨工序;降低了生产成本,提高了加工效率;无粉尘产生,改善了生产环境。 
附图说明
附图为本实用新型的结构示意图。 
图中:1、基体,2、前端,a、锥角。 
具体实施方式 
本实用新型的用于铣削内腔的刀具,包括一个杆铣刀,杆铣刀的基体1的前端2为梯形、梯形沿轴向长度为20mm、锥角a为15°。 
使用时将杆铣刀的基体1的端部安装在车床的刀架上,前端2对准待加工的零件,调整好同心度,启动车床就可一次性完成零件内腔的铣削。
