Automobile suspension lateral force spring full-stroke motion body outer diameter detection device and method

Abstract

The invention discloses an automobile suspension lateral force spring full-stroke motion body outer diameter detection device, which comprises a circular bottom plate, an annular gasket, an angle ruler, a bottom supporting block, a top supporting block, a diameter measuring scale, a scale limiting block and a detection end, and is characterized in that the annular gasket is concentrically and rotationally matched with the circular bottom plate; the angle ruler is concentrically and fixedly matched with the circular bottom plate; the bottom supporting block is detachably connected with the annular gasket; the top supporting block is detachably connected with the bottom supporting block; the diameter measuring scale is in sliding fit with the top supporting block; the scale limiting block is detachably connected with the top supporting block; and the detection end is detachably connected with one end of the diameter measuring scale. The automobile suspension lateral force spring full-stroke motion body outer diameter detection device has the advantages of simple structure and easy maintenance. The purpose of measuring the maximum outer diameter of each circle of a lateral force spring under each working condition is achieved, whether motion interference exists between the spring and peripheral parts of the spring or not is rapidly judged, and the development progress of an automobile chassis suspension system is accelerated.

Description

Technical field [0001] The present invention relates to the field of suspension detection devices, specifically an automobile suspension side force spring full stroke motion body outer diameter detecting device and a detection method thereof. Background technique [0002] Today, domestic and foreign cars are widely used by the McFesson suspension as a car chassis suspension, while the McFesson suspension arrangement will apply a reciprocal force to the shock absorber, which will not only wear the damper oil seal. And even make the piston rod to be bent failure. Therefore, the main plant has designed a lateral force spring, which is different from the general cylindrical spiral spring, and the central axis of the lateral force spring is a S-type or C-type curve, which can counteract the side force to improve the reliable car chassis system. sex. Since the lateral force spring center axis is not a straight line, it is necessary to measure the outer diameter of the lateral force spr...

Problems solved by technology

[0003] At present, the existing equipment on the market for measuring the outer diameter of the main body of the suspension lateral force spring in full stroke movement generally uses infrared rays to scan the whole spring to obtain a digital model of the spring, then measure the outer diameter of the main body, and output the outer diameter Although the use of infrared scanning equipment can accurately measure the change of the outer diameter of the spring's full travel, the price of the equipment is relatively expensive, and it has the disadvantages of harsh requirements for the place of use, easy damage and difficult maintenance. Now a cost Low-cost, easy-maintenance equipment to solve the above problems
