Abstract

本实用新型公开了一种改进型销轴,克服了现有技术中,金刚石压机销轴系统不易拆卸,对中性不好的问题。该实用新型含有两个花形套、纺锤体轴体,花形套和纺锤体轴体吻合套接,所述花形套的长度小于等于其与纺锤体轴体匹配的一端的长度。所述花形套和纺锤体轴体套接面与纺锤体轴体的中轴线的倾斜角为5°≤α≤35°。本实用新型具有以下优点:纺锤体轴体两端带有15度的夹角,从而易于安装,同时与两端花形套的配合,安装后可以使组合体销轴与销孔的公差配合趋于零,保障了六面顶压机的对中性精度,同时组合体且带有倾角的纺锤状主体便于安装、拆卸。能够提供一种高精度、易拆装、变形小的六面顶人造金刚石销轴。

Description

改进型销轴
技术领域
[0001] 该实用新型涉及一种六面顶人造金刚石压机的组件,特别是涉及一种改进型销轴。
背景技术
[0002] 现有技术的改进型销轴为传统圆柱体,不方便安装拆卸,易变形、拉毛或配合,间隙太大,影响压机的对中性。
实用新型内容
[0003] 本实用新型克服了现有技术中,金刚石压机销轴系统不易拆卸,对中性不好的问题,提供一种结构简单、使用方便的改进型销轴。
[0004] 本实用新型的技术解决方案是,提供一种具有以下结构的改进型销轴:含有两个花形套、纺锤体轴体,花形套和纺锤体轴体吻合套接,所述花形套的长度小于等于其与纺锤体轴体匹配的一端的长度。所述花形套和纺锤体轴体套接面与纺锤体轴体的中轴线的倾斜角为 5° < α < 35°。
[0005] 所述纺锤体轴体的两端沿其中轴线开有螺纹孔,旋入螺栓后能够将花形套和纺锤体轴体紧密压合在一起。所述花形套的圆周均匀分布有多个伸缩缝,伸缩缝的长度小于花形套的长度。所述花形套的圆周均匀分布有3个伸缩缝。
[0006] 与现有技术相比,本实用新型改进型销轴具有以下优点:与现有技术相比,纺锤体轴体两端带有15度的夹角,从而易于安装,同时与两端花形套的配合,安装后可以使组合体销轴与销孔的公差配合趋于零,保障了六面顶压机的对中性精度,同时组合体且带有倾角的纺锤状主体便于安装、拆卸。能够提供一种高精度、易拆装、变形小的六面顶人造金刚石销轴。
附图说明
[0007] 图1是本实用新型改进型销轴花形套的结构示意图;
[0008] 图2是本实用新型改进型销轴图1中Α-Α’的剖视结构示意图;
[0009] 图3是本实用新型改进型销轴纺锤体轴体的结构示意图;
[0010] 图4是本实用新型改进型销轴组合使用的剖视结构示意图。
具体实施方式
[0011] 附图说明中标号I是花形套,2是伸缩缝,3是纺锤体轴体,4是螺纹孔。
[0012] 下面结合附图和具体实施方式对本实用新型改进型销轴作进一步说明:如图所示,本实施例中含有两个花形套1、纺锤体轴体3,花形套I和纺锤体轴体3吻合套接,所述花形套I的长度小于等于其与纺锤体轴体3匹配的一端的长度。所述花形套I和纺锤体轴体3套接面与纺锤体轴体3的中轴线的倾斜角为5° < α <35°。
[0013] 所述纺锤体轴体3的两端沿其中轴线开有螺纹孔4,旋入螺栓后能够将花形套I和纺锤体轴体3紧密压合在一起。所述花形套I的圆周均匀分布有多个伸缩缝2,伸缩缝2的长度小于花形套I的长度。所述花形套I的圆周均匀分布有3个伸缩缝2.
[0014] 当带有倾角的纺锤状主体与花形套I连接,由螺丝拧紧行成一体,形成一个圆柱体,与销孔紧配合,更可靠的保障了六面顶液压机的对中性和精度。
