Abstract

The invention provides a device for measuring the spring stiffness coefficient. The device includes a protective supporting shell, a limiting supporting frame structure with a scale line, a stiffnesscoefficient measurement spring structure, test balls, a plastic indicator plate, a convenient-to-carry protective cover structure capable of marking, a foldable protective supporting base structure, an anti-falling stop block, a clamping hole and a fluorescent pasting strip, and the limiting supporting frame structure with the scale line is fixed on the front surface of the protective supporting shell. According to the device for measuring the spring stiffness coefficient, through arrangement of limiting screws and an adjusting handle, the grasped adjusting handle is twisted advantageously, the distance between the limiting screws is adjusted, and the need of placement of test balls with different diameters is met; through arrangement of a protective cover plate, a portable grab handle anda tightly propping bolt, the measuring device is carried by the grasped portable grab handle advantageously, and the convenience and rapidity of use are increased; and through arrangement of a rotating shaft, a fixing sleeve, a protective baffle and a fixing clamping column, the action of shielding protection can be achieved from the front advantageously, and the test balls are prevented from falling.

Description

technical field [0001] The invention belongs to the technical field of teaching equipment, in particular to a device for measuring spring stiffness coefficient. 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. Also known as "spring". Generally made of spring steel. The types of springs are complex and diverse. According to the shape, there are mainly coil springs, scroll springs, leaf springs, special-shaped springs, etc. The spring is a widely used reset element. The stiffness coefficient of the spring is the ratio of the axial force of the spring to the axial deformation (k=F / s), which is a parameter to measure the performance of the spring. Stiffness coefficient, that is, the stubborn coefficient (elastic coefficient). It describes the size of the elastic force produced by uni...
