为了进一步保证加工的精确性,还可以对导向杆14的位置进行微调,可以是在顶板13上设置微调通孔,导向杆14穿出微调通孔,并且导向杆14的上端与微调螺母10配合,微调螺母10的下端面与顶板13的上表面接触,微调螺母10的上端面与固定于顶板13的上表面上的上限位块9接触,当需要对导向杆14的位置进行微调时,拧动微调螺母10即可实现对位于微调螺母下方的导向杆14长度的调节。上限位块9可以与顶板13加工为整体式结构,也可以加工为分体式结构,然后再进行固定,本实用新型实施例中优选将上限位块9与顶板13设置为分体式结构,然后通过螺钉固定,当然也可以在微调螺母10的下端面与顶板13的上表面之间还可以设置下限位块11。In order to further ensure the accuracy of processing, the position of the
本领域技术人员还可以在导向杆14上设置延伸方向与导向杆14的延伸方向相同的键槽,微调通孔内表面具有相应的配合键槽,键槽与配合键槽内设置有防滑键12,这样在工作过程中导向杆14就不会发生转动,进而提高了加工的精确性。Those skilled in the art can also set on the

为了方便转动偏心轮3,还可以在偏心轮3上固定有手柄4,可以是在偏心轮3上设置螺纹孔,在手柄4的一端设置有螺纹,通过螺纹连接实现手柄4与偏心轮3的固定,当然还可以是其它的固定形式,只要能达到相同的技术效果即可。In order to rotate the
为了保证下底座19与偏心轮3接触,并且保证偏心轮3的较小,通常可以在下底座19与偏心轮3相对应的部位向上凸起2,该凸起2可以与下底座19为一体式结构,为了加工方便还可以将凸起2与下底座19设置为分体式结构,然后将凸起2与下底座19固定在一起,一般情况可以通过螺钉将凸起2与下底座19固定,当然也可以是其它的固定方式,只要能达到相同的技术效果即可。In order to ensure that the
