Abstract

本实用新型公开了一种丝杠,包括杆体,所述杆体的侧壁上设有多段均匀分布的外螺纹,所述杆体外螺纹中间段设有凹槽,所述凹槽的底部固定安装有复位弹簧,所述弹簧的上端固定连接有石墨块。本实用新型结构简单,防止丝杠卡死,对机床又清洁环保。

Description

丝杠
技术领域
本实用新型涉及一种丝杠。    
背景技术
    丝杠是机床上常用的部件,丝杠在使用过程中易出现卡死,转动不灵活的现象,润滑油的使用,使得机床自身更容易脏。
实用新型内容
本实用新型目的是提供一种结构简单,防止丝杠卡死,对机床又清洁环保的丝杠。
本实用新型解决技术问题提供如下方案:
一种丝杠,包括杆体,其特征在于:所述杆体的侧壁上设有多段均匀分布的外螺纹,所述杆体外螺纹中间段设有凹槽,所述凹槽的底部固定安装有复位弹簧,所述弹簧的上端固定连接有石墨块。
所述杆体的端部设有突出的连接轴,所述连接轴的侧壁上设有限位销。
    本实用新型在杆体的侧壁上设有凹槽,且在凹槽内固定安装有弹簧,且在弹簧的上端固定连接有石墨块,这样在使用过程中,石墨块在弹簧的作用下,石墨与丝杠套之间摩擦,留下石墨粉料,使得丝杠的转动更加润滑。
附图说明
图1为本实用新型的结构示意图。
具体实施方式
参见附图,一种丝杠,包括杆体1,所述杆体1的侧壁上设有多段均匀分布的外螺纹2,所述杆体外螺纹2中间段设有凹槽3,所述凹槽3的底部固定安装有复位弹簧4,所述弹簧4的上端固定连接有石墨块5。
所述杆体1的端部设有突出的连接轴6,所述连接轴6的侧壁上设有限位销7。

Claims (2)

1.一种丝杠,包括杆体,其特征在于:所述杆体的侧壁上设有多段均匀分布的外螺纹,所述杆体外螺纹中间段设有凹槽,所述凹槽的底部固定安装有复位弹簧,所述弹簧的上端固定连接有石墨块。 
2.根据权利要求1所述丝杠,其特征在于:所述杆体的端部设有突出的连接轴,所述连接轴的侧壁上设有限位销。
