Embodiment Construction
[0024] The present invention will be further described below in conjunction with specific drawings.
[0025] Such as Figure 1-Figure 3 As shown, the coating impact fatigue test device of the present invention comprises a base 1, a rotating shaft support 7 is installed on the base 1, a rotating shaft 6 on the rotating shaft support 7 supports a lever 4, and a speed regulating motor 5 is installed on the base 1 at the left end of the lever 4, The power output shaft of the speed-regulating motor 5 is connected to the turntable 3, and four shift forks 2 are arranged on the turntable 3 along the circumferential direction. During the rotation of the turntable 3, the four shift forks 2 can sequentially press down the left end of the lever for a certain distance, and then connect with the lever. Disengaged, so that the right end of the lever rises and falls freely, thereby realizing the repeated impact of the hard alloy ball fixed under the right end of the lever on the coating sampl...
