Description

凸轮轴钻孔夹具
技术领域
本发明属于凸轮轴机加工工装，具体涉及凸轮轴钻孔夹具。
背景技术
    现有技术中，一般在钻床上钻孔时，都是通过虎口钳固定好工件来加工的。对于一些圆筒形的工件，如凸轮轴，如果需要在其圆弧面上钻几个孔的话，就不太好固定了，定位难、操作复杂是不能满足现有钻孔加工需要的根本性缺陷，特别是对于工件的加工精度要求高，同时保证加工效率的情况下，现有的装夹器具明显不能满足要求。
发明内容
 本发明所要解决的技术问题是提供凸轮轴钻孔夹具，对于凸轮轴钻孔作业定位精准、操作方便，提高了装夹和加工效率，同时提高了加工精度。
为解决上述技术问题，本发明提供凸轮轴钻孔夹具，它包括底盘、定位轴和固定销，所述的底盘中部开与凸轮轴相适配的圆形孔，定位轴包括轴体和圆盘，轴体和圆盘一体连接，轴体外径与圆形孔内径相适应，轴体插入圆形孔，圆盘通过固定销与底盘相连接，使用时，将凸轮轴穿入圆形孔，通过固定销插入深度调整定位轴插入圆形孔长度对凸轮轴穿入圆形孔的长度进行精准定位。
优选地，所述的凸轮轴钻孔夹具还包括定位销，在底盘靠上的位置开有销孔，定位销通过销孔与底盘相连接，所述的定位销设置在定位轴圆盘略靠上的位置，对定位轴进行定位，从而实现对于凸轮轴二次定位，进一步提高凸轮轴加工精度。
优选地，所述的定位销为圆柱销。
本发明所提出的凸轮轴钻孔夹具，对于凸轮轴钻孔作业定位精准、操作方便，提高了装夹和加工效率，同时提高了加工精度。
附图说明
图1是本发明所提出的凸轮轴钻孔夹具俯视结构示意图。
图2是图1中A-A剖视结构示意图。
具体实施方式
参见附图，凸轮轴钻孔夹具，它包括底盘1、定位轴4和固定销5，所述的底盘中部开与凸轮轴2相适配的圆形孔，定位轴包括轴体40和圆盘41，轴体和圆盘一体连接，轴体外径与圆形孔内径相适应，轴体插入圆形孔，圆盘通过固定销与底盘相连接，使用时，将凸轮轴穿入圆形孔，通过固定销插入深度调整定位轴插入圆形孔长度对凸轮轴穿入圆形孔的长度进行精准定位。
优选地，所述的凸轮轴钻孔夹具还包括定位销3，在底盘靠上的位置开有销孔，定位销通过销孔与底盘相连接，所述的定位销设置在定位轴圆盘略靠上的位置，对定位轴进行定位，从而实现对于凸轮轴二次定位，进一步提高凸轮轴加工精度。
优选地，所述的定位销为圆柱销。
本发明所提出的凸轮轴钻孔夹具，对于凸轮轴钻孔作业定位精准、操作方便，提高了装夹和加工效率，同时提高了加工精度。
