Problems solved by technology

[0004] In related technologies, unidirectional fixed actuators are generally used to simulate the loading conditions of automobile parts. The actuator is fixedly arranged and can only be loaded in one fixed direction. If the part is subjected to a force in a non-fixed direction, multiple actuators need to be arranged to load the part separately; and a single-direction fixed actuator is used. The structure of the layout mechanism of the actuator is complex, the space is relatively large, and the cost is correspondingly high, which virtually increases the cost and design difficulty of the actuator layout mechanism

Abstract

This application relates to a ring track type actuator layout mechanism and test bench, including ring track, planetary gear outer gear, pulley assembly and actuator assembly, the ring track is provided with coaxial slots; the planetary gear outer teeth are Arc-shaped, fixed on one side of the circular track; the pulley assembly includes a connecting seat and a limit device, and the limit device overlaps the outer arc surface of the circular track; the actuator assembly includes a support, an actuator, and a planetary gear. Gear and drive motor, one end of the support is connected to the connecting seat of the pulley assembly; the inner gear of the planetary gear is set on one side of the support, meshing with the outer gear of the planetary gear; the drive motor is set on the other side of the support opposite to the inner gear of the planetary gear On the side, the output end of the driving motor is connected through the internal gear of the planetary gear of the support; when testing auto parts, only one actuator needs to be arranged to realize the circular rotation of the actuator, which can provide any Directional force loading.

Description

technical field [0001] The application relates to the technical field of auto parts testing, in particular to a ring-shaped track-type actuator arrangement mechanism and a test bench. Background technique [0002] The fatigue test of parts detects the fatigue characteristics, fatigue life, prefabricated Crack and crack growth test. Under the action of sufficiently large alternating stress, sudden changes in the shape of metal components or surface scratches or internal defects may cause microscopic cracks due to large stress concentrations. Scattered microscopic cracks will form macroscopic cracks after gathering and communicating. The formed macroscopic cracks gradually expand slowly, and the cross-section of the component is gradually weakened. When it reaches a certain limit, the component will suddenly break. The above-mentioned failure phenomenon of metal caused by alternating stress is called metal fatigue. Statistics show that about 70% of the failures of mechanic...
