Electric appliance reed elasticity value measuring device and electric appliance reed elasticity value measuring method

Abstract

The invention discloses an electric appliance reed elasticity value measuring device and an electric appliance reed elasticity value measuring method. The measuring device comprises a compression column, a compression piece and a pad column, wherein the compression piece is fixed on the compression column through a compression screw; the compression column comprises a connecting plate which is matched with the upper compression plate of a spring tensile and compression testing machine; the connecting plate is connected with the upper compression plate through a fastening device; the pad column is arranged on the lower compression plate of the spring tensile and compression testing machine; the pad column is provided with a clamp groove which is used for clamping measured reed parts; the compression piece comprises a compression head for compressing the electric appliance reed; the shape of the compression head is adaptive to a contact matched with the electric appliance reed; and the electric appliance reed elasticity value measuring method is that the testing machine compression plates are moved up and down to drive the compression column to compress the reed to stimulate working deformation of the electric appliance reed, so that the elasticity value that an abnormal-shaped reed deforms to specified amount can be read from a dial plate of the spring tensile and compression testing machine, therefore, the electric appliance reed elasticity value measuring device and measuring method are convenient to operate and good in repeatability, and can be used for accurately measuring the elasticity value of the reed; and the part quality is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of spring force detection, and in particular relates to a device for measuring the spring force value of an electrical reed and a measuring method thereof. Background technique [0002] In the product design, the electrical contacts use the contact-type connection method. In order to ensure reliable electrical connection and have certain reliability, it is necessary to control the elastic force value of the electrical contact. In the past, the spring force of electrical reeds was qualitatively controlled by hand feeling and visual inspection. This method is relatively extensive and cannot accurately measure the spring force value. At the same time, it cannot judge the durable pressure resistance of the reeds. The elastic force value control is not accurate, so that the quality of this type of parts cannot be guaranteed. Contents of the invention [0003] In order to solve the above-mentioned defects exist...
