Description

An automatic detection machine for relay armature displacement

technical field

The invention relates to the technical field of relay armature displacement detection technology, and in particular discloses an automatic detection machine for relay armature displacement.

Background technique

The size of the armature stroke in the electromagnetic relay affects the performance of the pull-in or release of the relay. Electromagnetic relay magnetic circuit

During the assembly process, due to the tolerance of each part and the difference of each assembly mold, after the magnetic circuit is assembled, the stroke error of the armature cannot be detected. At present, there is still no special testing instrument for detecting the stroke size of the armature, which affects the technical performance of the relay. CN202041140U proposes a plug gauge for detecting relay armature overtravel, by inserting the first plug between the armature and the iron core to detect the lower limit of the armature overtravel, and then inserting the first plug and the second plug into the armature at the same time Between the armature and the iron core, the upper limit value of the overtravel of the armature is detected. What this party detects is only the numerical range, and the exact value cannot be obtained. Furthermore, the thickness of the plug gauge is certain, and it is not necessarily necessary to insert two plug gauges at the same time. It is the upper limit of the overtravel, and the upper limit may be greater than or less than twice the plug gauge, so the plug gauge method cannot solve the essential problem of the relay armature stroke test.
