Abstract

The invention discloses a spring stiffness measurement structure, and relates to the field of spring test machinery, in particular to a spring stiffness measurement test device. The spring stiffness measurement structure comprises a test table and a hollow cylindrical gear type torsion spring fixer located on the test table; a shaft is coaxially arranged in the gear type torsion spring fixer; theshaft is connected with a power loader, and a force in an axial direction is applied; a gear is arranged on the outer wall of the gear type torsion spring fixer; the gear is meshed with a rack; the rack is connected with another power loader, and a force in a radial direction is applied; and during test, a spring of a test piece is arranged on the shaft in a sleeving mode, and a nut is used for limiting the displacement of the axial end of the test piece, and the other end of the test piece is connected to the test table. The device disclosed by the invention can be used for simultaneously detecting the conversion of the torsion and the compression amount of the spring of the test piece, and also can be used for performing measurement separately.

Description

technical field [0001] The invention relates to the mechanical field of spring testing, in particular to a spring stiffness measurement test device. Background technique [0002] Spring is the most commonly used component in various mechanical equipment and electronic equipment. How to measure the compression stiffness and torsional stiffness of any spring is of great significance. Existing special equipment cannot measure springs with large torque and torsion angle. Contents of the invention [0003] The spring stiffness measuring and testing device of the present invention is at least used to solve or overcome the problem that existing special equipment cannot measure springs with large torque and torsion angle. [0004] Spring stiffness measuring test device of the present invention comprises: [0005] The gear-type torsion spring holder is hollow cylindrical, and the outer wall is provided with a coaxial gear. A shaft is coaxially arranged at the center of the gear-t...
