Detailed Description

In order to make the technical means, the creation features, the achievement purposes and the functions of the present invention easy to understand, the present invention will be further explained below with reference to the following embodiments and the accompanying drawings, but the following embodiments are only the preferred embodiments of the present invention, and not all embodiments are included. Based on the embodiments in the implementation, other embodiments obtained by those skilled in the art without any creative work belong to the protection scope of the present invention.

Specific embodiments of the present invention will be described below with reference to the accompanying drawings.

Example 1

As shown in fig. 1 to 4, an elasticity calibrating device for a compression spring comprises a bearing machine body 1 and a fixing piece 3, wherein the fixing piece 3 is fixedly connected to the top end of the bearing machine body 1 at the central position, the fixing piece 3 is provided with a calibrating piece 2, the calibrating piece 2 comprises a sleeve 21, a threaded pipe 22, a counterweight ring 23 and a pressure detecting unit 24, the sleeve 21 is arranged above the bearing machine body 1, and the sleeve 21 is sleeved at the fixing piece 3; an overhanging threaded pipe 22 is fixedly connected at the top end port of the sleeve 21, a counterweight ring 23 is arranged on the periphery of the threaded pipe 22, and the counterweight ring 23 is bolted to the threaded pipe 22; a pressure detection unit 24 is attached to the bottom end port of the threaded pipe 22; wherein a spring is arranged below the calibration piece 2 and at the fixed piece 3, and the spring is sleeved at the fixed piece 3; the pressure detecting unit 24 is in contact with the spring.

In this embodiment, the standard spring is sleeved on the fixing member 3, the calibration member 2 falls from the fixing member 3 through the self-set standard height, and then contacts the standard spring at the calibration member 2 instantly, the elastic force of the standard spring is detected based on the reverse acting force of the standard spring to the calibration member 2, and after multiple detections, an upper error range and a lower error range are set, so as to facilitate the subsequent production of calibration, and detect whether the elastic force of the spring meets the standard within the error range.

In this embodiment, the spring need not to fix through anchor clamps, and promptly, the spring can be when the cover is in mounting 3 departments, based on 2 suppression springs of calibration piece, and then when the spring is reverse to apply elasticity, detects the elasticity coefficient of spring, and this testing process, not only fast can not drag because of the forcing of anchor clamps moreover, the spring elasticity that leads to damages the problem.
