The spring plate has various shapes and structures due to different uses. According to the shape, it can be divided into straight leaf spring and bent leaf spring. According to the shape of the plate, it can be divided into rectangle, trapezoid, triangle, stage shape, and special shape.
The characteristic of the spring piece is that it is easy to bend in one direction - Z small stiffness plane, while it has large tensile stiffness and bending stiffness in the other direction. Therefore, the leaf spring is very suitable to be used as the sensitive element, elastic support, positioning device, flexible connection, etc. in the detection instrument or automatic device.
According to the characteristics of the material, the spring plate is widely used in various kinds of contact devices, and the straight cantilever leaf spring with simple shape Z is mostly used. The resistance of the contact piece must be small, so it is made of bronze.
The function of the measuring leaf spring is to change the force or displacement. If the fixed structure and load-bearing mode can ensure that the working length of the spring is constant, the rigidity of the leaf spring is constant in the small deformation range. If necessary, nonlinear characteristics can also be obtained, such as pressing the spring onto the limit plate or adjusting screw and changing its working length.
