The invention discloses a plate spring calibration device. When calibration is conducted, a plate spring is placed on a worktable, a positioning seat is moved to extend into spring eyes of the plate spring, then a rotary knob is rotated to rotate a rotating shaft to drive a rotary gear to rotate, the rotary gear is engaged with two adjusting racks in a transmission mode, thus a sliding rod extendsto the outer part of a containing gun until a sliding sleeve abuts against the inner walls of the spring eyes, the sliding sleeve can slide, thus the rotary knob is continue to be rotated, the centering of the rotating shaft is coincided with the rounds of the spring eyes, a connecting rod is coincided with the connecting line of the centers of the two spring eyes, distance measuring is conductedby opening a diastimeter, reading is precise, and measuring errors are small.
Description
technical field [0001] The invention relates to the technical field of leaf spring calibration equipment, in particular to a leaf spring calibration device. Background technique [0002] Leaf spring is the most traditional elastic element in automobile suspension system. It has been widely used because of its good reliability, simple structure and low manufacturing cost. The leaf spring is composed of multiple pieces of alloy spring steel with different lengths, and the whole is in the shape of an arch beam, which plays a role in buffering vibration in the car and reduces the vibration of the car body. [0003] After the leaf spring is produced in the factory, it needs to be installed on the car. During installation, there are certain requirements for the arc height of the leaf spring. If the arc height of the leaf spring is too large, it will be difficult to install. If the arc height of the leaf spring is small, the vibration damping effect of the leaf spring will be grea...
