Description

Technical Field

[0001] The utility model relates to the technical field of shock absorber spring detection, in particular to a spiral spring blanking and detection device suitable for online detection of a formed shock absorber spring. Background Art

[0002] Shock absorber springs are an important part of the automobile suspension system. As a buffer between the suspension system or chassis and the ground, they can absorb and disperse the impact and vibration from the road surface, thereby maintaining the comfort and stability of the vehicle. Shock absorber springs are used together with shock absorbers. The function of shock absorbers is to suppress the shock when the spring rebounds after absorbing shock, reduce the vibration during the vehicle's driving process, and improve driving smoothness. The synergistic effect of the two can improve the comfort of the vehicle.

[0003] With the continuous development of the automobile industry, automobile manufacturers have continuously improved their requirements for automobile quality. In order to control product quality, it is necessary to detect the length of shock absorber coil springs. However, in actual production, there is no equipment that can detect the length of shock absorber coil springs online. Most of them are manually inspected after they come off the molding production line. The manual inspection method has the problems of high labor intensity and high false detection rate. Moreover, most of them are mass-produced first, and then the produced shock absorber coil springs are transferred to the inspection table for inspection. This kind of operation that separates production and inspection, when the shock absorber coil spring length is detected to be unqualified, a large number of unqualified products have often been produced, which in turn causes unnecessary waste of resources and seriously affects the production plan of the enterprise.
