The invention relates to a corner rotation loading device used for the fatigue strength test equipment of the automobile seat frame. The test seat is fixedly connected and installed above the machine base through the seat installation platform, and the position detection sensor is installed on the machine base through a bracket. side; the adjustment mechanism is fixedly connected to the other side above the machine base; the servo motor is installed on the installation platform of the adjustment mechanism, and the electric servo machine adjusts the angle with the test seat frame through the reducer, universal coupling, rotating hand wheel The torque sensor is connected between the reducer and the universal coupling, and the torque sensor is used to detect the load torque in real time. The servo motor is connected to the control system, which is controlled by the control system according to the detection standard requirements for the fatigue strength of the seat frame. The servo motor drives the recliner on the seat frame to rotate through the reducer, the universal coupling and the rotating hand wheel. The device can meet the detection requirements of different types and different models and sizes of relevant car seat frame fatigue strength test standards.
Description
technical field [0001] The invention relates to a testing device for fatigue strength testing of car seat frames, in particular to a rotating angle (reclinometer) rotating loading device for fatigue strength testing of various car front seat frames in the automotive industry. Background technique [0002] The safety of car seats is listed as one of the most important indicators in the overall performance of the car by the global auto industry. Because the car seat is not only a riding device but also a protection device, ensuring the safety of the car seat is an important task in the design and inspection of the car seat, and the fatigue strength of the seat frame is an important factor affecting the safety and life of the car seat. Therefore, the fatigue strength of the seat frame is a necessary safety performance testing index in the manufacturing process of various car seats, and an important means to ensure product performance, improve product quality and test product re...
