A kind of elastic measuring equipment and measuring method of contact spring

Abstract

The invention discloses a contact spring elasticity measurement equipment and a measurement method thereof, comprising: a support ring as a general support; a strut, which can move radially inward and outward along the support ring; a deformation acquisition unit, the contact spring is free When expanding the support, the deformation acquisition unit performs the same degree of expansion to realize the deformation acquisition of the contact spring; the force acquisition unit, the force acquisition unit is arranged on the inner side of the tooling position before the pole moves, to realize the force of the contact spring Acquisition; the measurement method of the elastic measuring equipment of the contact spring, including the following steps: S1: embedding; S2: measuring; S3: calculating the elastic coefficient of the contact spring, when the contact spring is freely expanded, the deformation acquisition unit performs simultaneous The degree of expansion, the deformation acquisition unit is provided with scales indicating the length before and after expansion along the circumference, and the elastic coefficient of the contact spring can be calculated by obtaining the deformation amount of the contact spring and the applied force.

Description

technical field [0001] The invention relates to the technical field of contact springs, in particular to a contact spring elasticity measurement equipment and a measurement method thereof. Background technique [0002] The contact spring is also called the plum blossom contact, and the plum blossom contact is used for primary conduction in high-voltage vacuum circuit breakers, central cabinets, and handcarts.

[0003] In the prior art, the publication number is CN110823434A, and the patent name is a kind of plum blossom contact elastic pressure detection device. In the literature, the measuring probe rod is elastically opened and contacted with the contact finger for measurement, and the measuring probe rod and the elastic connection device are used to measure Perform conversion measurement, there is no external impact interference during the measurement process, the measurement efficiency is high, the measurement is accurate and reliable, but the measurement can only detect the pressure of the spring, and the pressure is different when the spring is in different shapes, so it cannot be well judged whether the spring can continue to use

[0004] Moreover, the spring in the existing contact spring is ring-shaped. When using an external common elastic measuring device for measurement, it is necessary to know that the spring is under pressure and measure the difference between the length after deformation and the length before deformation, but the ring-shaped spring does not It is better to measure the difference between the length after deformation and the length before deformation. If the spring in the contact spring is taken out for manual measurement, the efficiency is low and it is troublesome to use.
