Description

Automobile steel plate detection device

Technical Field

The utility model belongs to the technical field of stress detection for automobile steel plate springs, and particularly relates to an automobile steel plate detection device.

Background

The automobile leaf spring is also called a leaf spring, and is commonly called a leaf spring in northern areas; leaf spring: is formed by overlapping a plurality of steel plates with unequal lengths and unequal curvatures; after the installation, the two ends naturally bend upwards; when the impact force of the road surface to the wheels is transmitted, the steel plate deforms, so that the effects of buffering and vibration reduction are achieved, and the longitudinal arrangement also has the effect of guiding the impact force; most of the non-independent suspension adopts leaf springs as elastic elements, so that a guide device and a damper can be omitted, and the structure is simple; the leaf spring is the most widely used elastic element in the automotive suspension, and is an elastic beam with approximately equal strength formed by combining a plurality of alloy leaf springs with equal widths but unequal lengths (the thicknesses can be equal or unequal); when the leaf spring is arranged in an automobile suspension and the vertical load born by the leaf spring is positive, each leaf spring is stressed and deformed, and the leaf spring tends to arch upwards; at this time, the axle and the frame are close to each other; when the axle and frame are moved away from each other, the normal vertical load and deformation to which the leaf spring is subjected is gradually reduced, sometimes even reversed. The main film rolling lug is severely stressed and is a weak part, and in order to improve the stress condition of the main film rolling lug, the tail end of the second film is often bent into a rolling lug, and the second film is wrapped outside the main film rolling lug, which is called a wrapping lug; in order to enable the sheets to have relative sliding possibility during elastic deformation, a larger gap is reserved between the main sheet winding lug and the second sheet wrapping lug; the two ends of the leaf spring in some suspensions are not made into coiled lugs, but other supporting connection modes, such as rubber supporting pads, are adopted; the flat rectangular steel plate is a bending type spring for a chassis formed by stacking a plurality of pieces, one end of the spring is arranged on the hanging bracket by pins, and the other end of the spring is connected to the girder by hanging lugs, so that the spring can stretch and retract.

At present, when manufacturing factories produce leaf springs, cracks appear in a part of steel plates, and the steel plates with cracks need to be welded for continuous use, but the welding parts of the steel plates have stress, if the stress of the welding parts cannot meet the requirement of an application area, the welding parts of the steel plates cannot be used, if the compressive stress of the application area is larger than that of the welding steel plates, the situation that the welding parts of the welding steel plates are cracked again, and even the situation that the welding parts are broken still appears, so the practicability of the welding steel plates is reduced, so that the stress detection of the welding steel plates at present is needed, but the current stress detection of the welding steel plates is inconvenient, and therefore, the application provides an automobile steel plate spring stress detection device.
