Detection measure of leaf spring

Abstract

The invention belongs to the automobile detection field and relates to a detection measure of a leaf spring. The detection measure comprises a measure body; the measure body is rectangular on the whole; an end portion of the measure body is provided with a detachably-connected fixing disc; the center of the fixing disc is corresponding to the center hole of a wrapping eye; the diameter of the fixing disc is larger than the diameter of the wrapping eye; the lower edge of the measure body is provided with a plumb which is in sliding connection with the lower edge of the measure body; a side surface of the measure body is provided with a scale marking line plate; and the starting point of the scale marking line plate is located at the joint of the fixing disc and the measure body. According to the detection measure of the invention, the center of the leaf spring is determined accurately through the plumb, so that the accuracy of detection results of the measure can be ensured.

Description

technical field [0001] The invention relates to the field of automobile detection, in particular to a detection measuring tool for leaf springs. Background technique [0002] Leaf spring is the most widely used elastic element in automobile suspension. It is an elastic beam of approximately equal strength composed of several alloy spring sheets of equal width but unequal length. When the leaf spring is installed in the automobile suspension and the vertical load it bears is positive, each spring leaf is deformed by force and tends to arch upward. At this time, the axle and frame are close to each other. When the axle and frame move away from each other, the positive vertical load and deformation of the leaf spring gradually decreases, and sometimes even reverses. Whether the leaf spring is a qualified product or not, one of the most important technical indicators is to detect the distance between the center hole of the coil ear and the center hole of the entire product.

Problems solved by technology

However, this document has the following problems: Since the overall structure of the leaf spring is a depression in the middle, and the other two ends are bent upward, when the measuring tool is used to hang the ear hole of the roll with a hook, the part marked with the scale mark in the measuring tool is not the same as the leaf spring. There is a certain distance in the vertical direction of the middle concave part of the product, and the position of the center hole of the product cannot be accurately determined, resulting in inaccurate test results
