Abstract

本实用新型公开了一种螺纹活块锁紧装置,其包括螺母,螺母内圈开有槽,槽内嵌有活块,活块的一面设置螺纹且与所述螺母的内圈配合,活块的另一面设置紧定螺钉,紧定螺钉与所述螺母上设置的螺纹通孔配合连接。本实用新型成本低,仅通过活块结构和螺钉即能实现对螺母的锁紧。

Description

螺纹活块锁紧装置
技术领域
本实用新型涉及锁紧装置,具体地说是一种螺纹活块锁紧装置。
背景技术
为防止轴系上螺母的轴向移动,需要对其进行锁紧。现有的锁紧技术主要为双螺母并紧,该锁紧结构从效果上来讲并无缺陷,但当主轴的直径较大时,螺母本身成本较高,如果依然采用前述双螺母并紧的方式,加大了零件的制造成本。
发明内容
本实用新型针对现有技术存在的上述不足进行研究和改进,提供一种螺纹活块锁紧装置,结构简单、成本低。
为了解决上述技术问题,本实用新型采用如下的技术方案:
本实用新型包括螺母,螺母内圈开有槽,槽内嵌有活块,活块的一面设置螺纹且与所述螺母的内圈配合,活块的另一面设置紧定螺钉,紧定螺钉与所述螺母上设置的螺纹通孔配合连接。紧定螺钉外侧绑有钢丝。
本实用新型的技术效果在于:
1、成本低,仅通过活块结构和螺钉即能实现对螺母的锁紧。
2、结构简单、锁紧效果好,螺钉外侧收到钢丝的绑紧力,进一步加强了锁紧效果。
附图说明
图1为本实用新型的结构示意图,图中局部剖视;
图2为图1的右视图,图中局部剖视;
图3为图1中A处的放大图。
具体实施方式
见图1、图2,本实用新型包括螺母1,螺母1的内圈开有槽,活块2嵌与所述槽内,见图2,活块2的下底面设置螺纹且与螺母1的内圈配合,活块2的上表面与螺母1抵接,即当活块2嵌入所述槽内后,螺母1从形状上来看与完整的螺母无异。见图3,活块2的上表面连接紧定螺钉5,紧定螺钉5与螺母1上所设置的螺纹通孔6配合连接。
本实用新型使用时,螺母1连同活块2与主轴3螺纹连接,当需要紧固时,旋紧紧定螺钉5即可固定住活块2,进而限制了螺母1旋转运动的趋势,实现了对螺母1的轴向锁紧。同时,钢丝4绑在螺母1的外圈并经过紧定螺钉5,其对紧定螺钉5产生的绑紧力进一步巩固了对螺母1的锁紧效果。
