A Programmable Spring Endurance Testing Machine

Abstract

The invention discloses a programmable spring durability testing machine, which includes a body, a chute, a first groove, a guide rail, a PLC controller, a first screw, a slider, a spring clamp, a second screw, a third Lead screw, fourth lead screw and moving block. The invention controls the stretching length and stretching frequency of the spring in the detection process through the PLC controller, and the detection data is more, which is more convincing; it can not only detect the maximum elastic deformation of the spring, but also detect the tensile strength of the side end , the detection function is comprehensive, and the detection effect is more obvious; each structure cooperates with each other, has strong practicability, and can be widely used in spring quality detection. It solves the problems in the prior art that only single-stroke and single-frequency detection of the spring is not convincing, and the tensile strength of the side end of the spring cannot be detected.

Description

technical field [0001] The invention belongs to the field of spring durability testing, in particular to a programmable spring durability testing machine. Background technique [0002] A spring is a mechanical part that uses elasticity to work. Parts made of elastic materials are deformed under the action of external force, and return to their original shape after the external force is removed. In actual production, the quality of the spring needs to be tested. The maximum elastic deformation of the spring and its lateral end tensile strength need to be tested before being put into use. For its quality testing, spring durability testing machines are generally used for testing nowadays, and often only the maximum elastic deformation of the spring can be tested, and all of them are single-stroke and single-frequency. The effect of this detection method is single, and its detection result is not convincing, and the tensile strength of the side end of the spring cannot be det...
