Abstract

The invention discloses a manual spring tension and compression testing machine which aims to solve the problems that spring elasticity coefficients are detected by special equipment mostly made of electronic components currently and the special equipment is not applicable to field operation and the like. The manual spring tension and compression testing machine comprises a frame, a measuring mechanism, a transmission mechanism and a tension and compression clamp mechanism. The measuring mechanism comprises a wide-range vernier caliper (12), a small-range vernier caliper (16) and a spring (5). The spring (5) is sleeved on an upper pressing plate guide rod (3), the upper end of the spring (5) is fixed with a middle crossbeam (6), the lower end of the spring (5) is fixed with an upper spring pressing plate (15) of the tension and compression clamp mechanism, an upper measuring jaw of the small-range vernier caliper (16) is fixed with the middle crossbeam (6), a lower measuring jaw of the small-range vernier caliper (16) is fixed with the lower surface of the upper spring pressing plate (15), an upper measuring jaw of the wide-range vernier caliper (12) is fixed with the upper surface of an upper crossbeam (10), and a lower measuring jaw of the wide-range vernier caliper (12) is fixed with the lower surface of the upper spring pressing plate (15).

Description

technical field

[0001] The present invention relates to a measuring device, more precisely, the present invention relates to a measuring device which can be manually operated and more accurately measure the applied force and elastic coefficient of compression springs and extension springs. Background technique

[0002] With the development of industry, various springs have been more and more widely used in various fields. In many occasions and structures, springs rely on the force generated by spring deformation to determine whether the spring can be deformed in a certain way. To provide the required force, it is necessary to measure the elastic coefficient of the spring. If there is a slight variation in the deformation of the spring in the working state, it will cause adverse consequences to the entire structure. The force realizes the opening and closing of the valve under a specific pressure, and the spring deformation force can be used to maintain the normal pressure re...
