Description

Technical Field

[0001] The utility model relates to the technical field of spring measurement, in particular to a measuring ruler for spring processing. Background Art

[0002] A spring is a mechanical part that uses elasticity to work. Parts made of elastic materials deform under external force and return to their original shape after the external force is removed. There are many types of springs. According to their shapes, they mainly include round springs, helical springs, scroll springs, leaf springs, and special-shaped springs.

[0003] The existing patent (publication number: CN219674979U) discloses a spring measuring tool, including: a base, on which a first measuring reference plane is arranged; a side plate, which is arranged on the base, and a second measuring reference plane is arranged on the side plate, and the second measuring reference plane is perpendicular to the first measuring reference plane; a vertical fixing rod, which is arranged on the base, and the vertical fixing rod is perpendicular to the first measuring reference plane; a height needle, which is slidably connected to the vertical fixing rod in a lockable manner; a transverse fixing rod, which is arranged on the vertical fixing rod and is located below the height needle, and the transverse fixing rod is perpendicular to the second measuring reference plane; a width needle, which is slidably connected to the transverse fixing rod in a lockable manner. The spring measuring tool of the utility model has its own reference surface, which can quickly measure the height and core diameter of the spring.

[0004] When the above patent is used, it can only measure the height and core diameter of the spring, while the elastic force of the spring is an important parameter for evaluating the performance of the spring. In order to ensure the pass rate of the spring, each manufacturer needs to test the elastic force of the spring. When the elastic force of the spring needs to be tested, it is necessary to use another measuring device, which not only has low detection efficiency but also high cost. Therefore, a measuring ruler for spring processing is proposed. Utility Model Content
