Spring test machine and spring detection method thereof, control device and storage medium

Abstract

The invention discloses a spring detection method which is applied to a spring test machine. The spring detection method comprises following steps of: when a to-be-tested spring is fixed in each work station, acquiring pressure information detected by a pressure detection module; according to the pressure information, determining position information of each to-be-tested spring; determining whether each piece of position information matches corresponding preset position information; if yes, controlling the press device to press down according to preset test parameters, so as to enable each test jig to compress corresponding to-be-tested spring and detect force generated when the to-be-tested spring is pressed. The invention further discloses a control device, a spring test machine and a readable storage medium. The method aims to reduce measurement errors of spring tests and improve reliability of spring test results.

Description

technical field [0001] The invention relates to the technical field of spring detection, in particular to a spring detection method, a control device, a spring testing machine and a readable storage medium. Background technique [0002] At present, in order to ensure the service life of springs in products (such as mattresses), anti-fatigue tests are generally carried out on different springs to select springs that meet product requirements. [0003] However, in the current process of testing a batch of springs of different specifications, the springs are usually manually fixed on the workstations of the workbench to start testing directly. Due to the large randomness of manual operations, each spring is relatively The positions of the fixtures are not uniform, and it is impossible to guarantee that the test fixtures on the spring testing machine exert a consistent force on each spring, which will easily lead to large measurement errors and affect the reliability of the spri...
