Abstract

The invention relates to an automobile spring collision bead assembly service life testing machine with a coating and eccentric wheel mechanism. A bottom fixing plate and a top fixing plate are fixedly connected through four guide columns, a middle fixing plate is arranged between the bottom fixing plate and the top fixing plate and connected with the four guide columns in a guiding and sliding mode, holders which are used for installing spring beads and distributed evenly are installed on the upper surface of the bottom fixing plate, a stepless speed control motor is installed on the lower end face of the upper fixing plate, a pull rod is fixedly connected with the upper surface of the middle fixing plate, pressure measuring heads evenly distributed in correspondence with the holders are fixedly connected with the lower surface of the middle fixing plate, and an eccentric wheel is installed on the output shaft of the stepless speed control motor and is in rolling contact connection with rolling bearings installed at the upper end of the pull rod. A spring bead assembly is convenient to clamp, the fatigue life of the multiple sets of spring beads can be simultaneously measured through the multiple sets of spring bead holders, and great significance is achieved for improving the testing efficiency. Grooves are formed in the two side faces of the oval eccentric wheel, the rolling bearings roll vertically in the grooves of the eccentric wheel, and the middle fixing plate is driven to move vertically.

Description

technical field [0001] The invention relates to a life testing machine for a spring bead assembly, in particular to a life testing machine for an automobile spring bead assembly of a coated eccentric wheel mechanism. Background technique [0002] The automobile industry has developed rapidly in recent years. The fierce competition among manufacturers not only includes the competition of sales skills, but also includes a series of competitions such as automobile production efficiency, performance of automobile parts, and automobile quality. The competition in the performance of auto parts is mainly the fatigue times of the parts, that is, the maximum number of times the parts can be used before fatigue failure. Automobile spring bead assembly fatigue life testing machine is a machine for testing the fatigue life of automobile spring bead assembly. The life testing machine of automobile spring bead assembly can greatly improve the life test efficiency of automobile spring bea...
