Device for testing rigidity of plate spring in high-temperature environment

Abstract

The invention discloses a device for testing the rigidity of a plate spring in a high-temperature environment. The current testing method is poor in testing precision, cockamamie in process and poor in universality as the current testing method is carried out after a spiral spring high-temperature testing device is transformed according to the structure and the shape of the plate spring. The device comprises a clamping device used for clamping the plate spring, a force testing device used for testing plate spring bearing loads, a lifting device used for regulating the position of the force testing device, a deflection measuring device used for measuring the deformation amount of the plate spring, a regulating device used for regulating the positions of stress action points of the plate spring, and an electromagnetic induction heating device used for stimulating the working temperature of the plate spring. With the adoption of the device for testing the rigidity of the plate spring in the high-temperature environment, the continuous measurement on different deflections and different stress action points can be realized; and the device is convenient to operate and reliable in test.

Description

technical field [0001] The invention belongs to the field of leaf spring stiffness testing devices, in particular to a device for testing the stiffness of leaf springs in a high-temperature environment. Background technique [0002] Leaf springs use the deformation force generated by the bending of metal sheets to play the role of springs. They have the characteristics of simple structure, convenient processing, and small space occupation. They are widely used in power contact devices, instrumentation devices, and mechanical control systems. Status is important. The stiffness of a leaf spring refers to the load required to produce unit deformation. It is one of the most important indicators for evaluating the performance of a leaf spring, and it is also a key parameter to consider when designing and selecting a leaf spring. Temperature is one of the main factors affecting the stiffness of the leaf spring. As the temperature increases, the elastic modulus and stiffness of th...

Problems solved by technology

Most of the current test methods are based on the structure and shape of the leaf spring after modifying the high-temperature test device for the coil spring. This test method has poor test accuracy, cumbersome process, and poor versatility. There are many types of leaf springs actually used. A specially designed clamping device, which undoubtedly increases the complexity of the test and reduces the test efficiency
