Elasticity detection device for plate spring and method for detecting plate spring by using same

Abstract

The invention discloses an elasticity detection device for a plate spring and a method for detecting the plate spring by using the same. The elasticity detection device comprises a plate spring base and a power applying device, wherein the power applying device comprises a guide mechanism, a push rod base is assembled horizontally on the guide mechanism in a movable manner, a push rod is assembled on the push rod base in a guided and movable manner, an elastic piece is arranged between the push rod base and the push rod, and a contact end is arranged at the front part of the push rod. In measurement, one end of the plate spring is fixed on the plate spring base, and the free end of the plate spring is dead against the contact end of the push rod; the push rod base is pushed to drive the push rod to move forward, so that the contact end of the push rod presses the free end of the plate spring to swing forward and the elastic piece between the push rod and the push rod base generates elastic deformation; when the free end of the plate spring swings forward to reach the elastic deformation required in the plate spring detection, the elastic deformation of the elastic piece is compared with a preset standard range; the plate spring is qualified if the elastic deformation of the elastic piece is in the preset standard range; otherwise, the plate spring is unqualified.

Description

technical field [0001] The invention belongs to the technical field of leaf spring spring force detection, and in particular relates to a leaf spring spring force detection device, and at the same time, the invention also relates to a detection method using the device to detect leaf springs. Background technique [0002] At present, in high-voltage electrical products, various types such as figure 1 The small leaf springs shown are very versatile. The leaf spring changes from the natural state A to the force state B after being compressed. The distance between the free end D of the leaf spring and the reference line C when the leaf spring is in the force state B is the required deformation dimension H. A qualified leaf spring requires When the deformation size reaches H, it has elastic force F, and when the deformation size reaches H, the spring force of the leaf spring exceeds or is less than F, which are unqualified springs. Considering the influence of processing errors...
