Abstract

The invention provides a spring strength fatigue testing device which is used for testing springs. The spring strength fatigue testing device comprises a bearing frame, a drive and a pressure sensor; the bearing frame comprises fixed guiding pillars, a movable bearing plate and a first pressure plate; the drive comprises a drive element and a control unit, the drive element drives the movable bearing plate to move towards the first pressure plate so as to enable the testing springs to be compressed between the first pressure plate and the movable bearing plate; the pressure sensor comprises a sensor host and a sensing element, the sensing element is used for sensing pressure exerted on the first pressure plate, the sensor host is in signal communication with the control element, and the control element controls the force exerted on the movable bearing plate by the drive element so as to enable the pressure, sensed by the sensing element, of the first pressure plate to be equal to a pressure target value. By the arrangement, spring strength can be automatically subjected to fatigue testing.

Description

technical field [0001] The invention relates to a spring strength fatigue testing device. Background technique [0002] Springs are widely used in lamps, especially flashlight lamps. Springs are mainly used as electrodes in flashlight lamps. In use, it will be subjected to positive pressure for a long time, causing the spring to be in a compressed state for a long time. If the strength of the spring is not good, it cannot recover after long-term pressure, resulting in poor contact of the lamp. Therefore, the quality of the spring strength greatly affects the overall performance of the lamp. [0003] The spring strength fatigue test often takes a long time. If manual operation is used, a lot of labor costs will be wasted, and it is not easy to ensure that the spring is subjected to a constant pressure during the test. Contents of the invention [0004] The object of the present invention is to provide a spring fatigue testing device, which can automatically perform fati...
