Equal-camber steel plate spring detection system

Abstract

The invention belongs to the technical field of steel plate spring manufacturing, and discloses an equal-camber steel plate spring detection system. The system comprises a rack and further comprises a positioning table and a hydraulic cylinder, wherein the hydraulic cylinder is connected to the rack through a rotating motor, a guide rail is installed on a piston rod of the hydraulic cylinder, and sliding rods are installed at the two ends of the guide rail; and a positioning column is arranged on the positioning table, a positioning hole matched with a center bolt of the steel plate spring is formed in the positioning column, and a second pressure sensor is installed in the positioning hole. According to the scheme, the camber of the steel plate spring can be rapidly measured, special loads borne by the steel plate springs on the two sides in the state that the inner height and the outer height are different when an automobile turns can be simulated on the basis that the camber of the steel plate spring meets the requirement, the anti-roll performance of the steel plate spring is further measured, the working efficiency is improved, the applicability is wide, and popularization is worthy.

Description

technical field [0001] The proposal belongs to the technical field of leaf spring manufacturing, and specifically relates to a detection system for equal-arc-height leaf springs. Background technique [0002] Leaf springs are the most critical shock absorbing components in automobile suspension systems. Different cars are equipped with leaf springs of different specifications, and the same car must be paired with leaf springs. The error of the arc height should be within the allowable range to ensure the safe driving of the car. Otherwise, it will not only affect the assembly, but also affect the driving safety of the car. Since the production consistency of the arc height of the leaf spring is difficult to guarantee, it is generally according to the given The specified tolerance is marked in thirds. When assembling, select the leaf springs with the same group identification for loading. However, there are marking errors, quality problems of the parts themselves and the fa...

AI Technical Summary

Problems solved by technology

This solution has a single function and can only detect whether the arc height of the leaf spring meets the requirements. However, in actual use, when the car is turning, it will be subjected to centrifugal force, and the body will roll under lateral acceleration, which will easily cause accidents such as rollover. Moreover, the comfort of the people in the car and the maneuverability of the car are reduced, which indirectly reduces the safety factor.
