Description
技术领域technical field
本发明涉及磁性表座的磁力检测技术，特别是一种全自动磁性表座磁力检测装置。The invention relates to a magnetic detection technology for a magnetic watch base, in particular to a fully automatic magnetic detection device for a magnetic watch base.
背景技术Background technique
磁性表座吸附在铁磁性表面（一般都是机床表面）后，相关仪器再固定于磁性表座上进行测量。在航天加工、装配的各种场合都有广泛的应用，比如常用做千分表或百分表固定在机床上的磁性表座，是千分表或者百分表在使用中不可或缺的一部分。工作磁力是磁性表座的一个主要参数，对表座安全使用有很大的参考价值。磁性表座在接通磁路后，工作面上的工作磁力必须达到的最小磁力值。如果磁性表座没有达到最小磁力的要求，在使用过程中轻则损坏仪器，重则危害检测人员的安全。目前常采用的磁性表座检定方法依据JB/T10010-1999《磁性表座》标准，这种检测方法主要靠人力牵拉磁性表座，牵拉磁性表座的牵拉绳上设置有测力器，检测人员边增加牵引力边读取测力器数据。现有的检测方式存在一定的问题，即如果磁性表座不合格，也就意味着在达到最小磁力前，磁性表座就会脱离铁磁性表面并在惯性作用下快速运动，而此时检测人员正在近距离读取测力器上的数据，非常容易被运动中的磁性表座伤害，并会磕碰损坏磁性表座。After the magnetic watch base is adsorbed on the ferromagnetic surface (usually the surface of the machine tool), the related instruments are then fixed on the magnetic watch base for measurement. It is widely used in various occasions of aerospace processing and assembly. For example, it is often used as a dial indicator or a magnetic base fixed on a machine tool. It is an indispensable part of the dial indicator or dial indicator in use. . The working magnetic force is a main parameter of the magnetic watch base, which has great reference value for the safe use of the watch base. After the magnetic watch base is connected to the magnetic circuit, the working magnetic force on the working surface must reach the minimum magnetic force value. If the magnetic base does not meet the minimum magnetic force requirements, the instrument may be damaged during use, and the safety of the testing personnel may be endangered. At present, the commonly used verification method of magnetic watch base is based on JB/T10010-1999 "Magnetic Watch Base". This detection method mainly relies on manpower to pull the magnetic watch base. , the inspector reads the data of the dynamometer while increasing the traction. There are certain problems in the existing detection methods, that is, if the magnetic watch base is unqualified, it means that the magnetic watch base will break away from the ferromagnetic surface and move rapidly under the action of inertia before reaching the minimum magnetic force. When reading the data on the dynamometer at close range, it is very easy to be damaged by the magnetic watch base in motion, and the magnetic watch base will be damaged by collision.
