Abstract

一种环规,包括内环,内环的内表面设置有合金。本实用新型的目的在于提供一种新型环规,解决了传统环规中的测量精度不高、尺寸不稳定以及圆度差等技术问题。

Description

一种环规
技术领域
本实用新型公开了一种测量用具,特别是一种用于对表进行比较的环规。
背景技术
用于对表进行比较的环规的结构如图1所示,包括内环,该内环是普通的金属制成,长期使用容易磨损,使其测量精度低,尺寸不稳定,圆度差。
实用新型内容
本实用新型的目的在于提供一种新型环规,解决了传统环规中的测量精度不高、尺寸不稳定以及圆度差等技术问题。
一种环规,包括内环,其特征是:所述内环的内表面设置有合金。
作为优选方案,如上所述的内环的内表面焊接有合金。
本实用新型将传统的普通的金属内环的内表面设置为合金材质,使其耐磨程度高,测量精度高,尺寸稳定,圆度高。
附图说明
图1是传统的环规的结构示意图;
图2是本实用新型提供的环规的结构示意图。
具体实施方式
参见图2,本实用新型公开了一种全新的环规,内环的内表面设置有合金,最好是焊接有合金。当然,如果采用合金制成的内环也明显优于传统普通的金属内环。本实用新型是对表进行比较,其测量尺寸稳定,圆度高(圆度±0.5μm)。

Claims (2)

1.一种环规,包括内环,其特征是:所述内环的内表面设置有合金。
2.如权利要求1所述的环规,其特征是:所述内环的内表面焊接有合金。
