【技术实现步骤摘要】
加长刀柄用接套
本技术属于机加工辅助设备,特别涉及一种用于数控机床延长刀具夹持长度的加长刀柄用接套。
技术介绍
目前在机械加工中经常碰到有径向干涉的部位,必须通过加长刀具才能加工,但刚性不够效率低下,同时保证不了产品图纸要求。
技术实现思路
针对生产中遇到的问题,本技术设计了一种在不改变刀具长径比的情况下延长刀具夹持长度的加长刀柄用接套。本技术的技术方案如下:加长刀柄用接套,其特征在于:包括连接套,连接套外表面的左端设有外锥面,在外锥面的末端的连接套的表面设有轴肩部,所述的连接套沿轴线设有通孔,所述的通孔包括由左向右一次设置的第一通孔、第二通孔和第三锥度孔,位于第三锥度孔末端的连接套上对称设有键块,所述的轴肩部设有动力传递套,动力传递套上设有与主轴配合的传递槽,还包括一个拉钉,拉钉包括拉杆,拉杆的一端设有连接部,靠近连接部的拉杆上设有限位部,拉杆的另一端设有螺纹部,拉钉插入通孔内,且拉钉的限位部与通孔的端面相抵,并拉钉的螺纹部位于第三锥度孔内。进一步的说,所述的连接部包括在拉杆端部形成的锥台,以及与锥台连接的圆柱部,圆柱部的末端设有第二锥台,第二锥台与限位部之间形成一 ...
