Problems solved by technology
[0003] At present, the spring elasticity of the upper pin spring is generally tested using a mechanical spring tension-compression testing machine. Do not test the stiffness curve and damping ratio
If you want to improve the technical parameters of the upper pin spring to obtain better stress relaxation resistance, the existing testing equipment cannot provide the corresponding technical data, making it impossible to start the research

Description
technical field [0001] The invention relates to the technical field of engineering detection, in particular to a digital display elastic measuring instrument used to measure the stiffness curve and damping ratio of an upper pin spring under different processing conditions. Background technique [0002] The upper pin spring, as the part that directly affects the spinning quality among the many parts of the pneumatic pressure cradle, its importance is self-evident. It belongs to a U-shaped leaf spring, and its elastic function can reduce the pressure fluctuation of the jaws of the apron and adjust the unstable operation of the apron caused by various reasons. For the upper pin spring, stress relaxation and elastic decline are its main failure modes, and the elastic decline will lead to the gradual or even complete loss of its function. If the stress of the upper pin spring is relaxed during work, it will cause uneven thickness of the spun yarn, which will seriously affect the...
