Description

一种夹持螺纹部位的夹具
技术领域
本实用新型涉及一种夹持螺纹部位的夹具,属于机械加工器械技术领域。
背景技术
在车床上加工带有螺纹的零件,又需要夹持螺纹部位时,由于螺纹外形是螺旋形的三角形,其夹持受力点在螺纹牙顶,是线接触,这样就容易损坏螺纹,导致螺纹不通。
实用新型内容
本实用新型的目的是为了克服现有技术中的不足,从而提供一种夹持螺纹部位的夹具。
一种夹持螺纹部位的夹具,包括夹具体、楔销、滑块、销子、开口销、楔销孔,所述夹具体内部中心设有滑块;所述楔销穿设于夹具体上开设的楔销孔和滑块的孔上;所述楔销一端设有销子,销子上设有开口销。
所述夹具体一端设有内螺纹,夹具体另一端设有夹持柄。
所述楔销上设有销孔。
采用上述技术方案的有益效果是:
本实用新型在车床上加工带有螺纹的零件时,有效减少损坏螺纹,导致螺纹不通的目的。
附图说明

图5为图1中楔销结构示意图。
图中:201-销孔。
具体实施方式
下面结合附图对本实用新型作进一步详细说明:
一种夹持螺纹部位的夹具,包括夹具体1、楔销2、滑块3、销子5、开口销6、楔销孔102,所述夹具体1内部中心设有滑块3;所述楔销2穿设于夹具体1上开设的楔销孔102和滑块3的孔上;所述楔销2一端设有销子5,销子5上设有开口销6。
所述夹具体1一端设有内螺纹101,夹具体1另一端设有夹持柄103。
所述楔销2上设有销孔201。
使用时,首先把工件4装入夹具体1的内螺纹孔中,工件4左端接触滑块3的右端面,把楔销2向上推出,保持如图2所示的间隙,然后用手把工件4拧紧,最后把楔销2向下轻敲,如图3所示,楔销2锁紧工件4。车削时,切削力使夹紧更加牢固。加工完毕,只要轻轻敲松楔销2,夹紧力消除,就可旋出工件4。
