Detailed Description

The present invention will be described with reference to the accompanying drawings.

As shown in fig. 1-2, the pendulum impact test mechanism of the present invention comprises a lifting support plate 11, a swing driving device 12, a rotating shaft box 13, a swing arm 14, a pendulum suspension rod 15, a pendulum 16, and a stop assembly; the lifting support plate 11 is provided with a structure matched with a lifting screw rod so that the whole lifting support plate can be lifted, the swing driving device 12 and the rotating shaft box 13 are both arranged on the lifting support plate 11, the rotating shaft box 13 is provided with a swing rotating shaft, the rotating shaft box 13 is provided with a dial 18 matched with the swing rotating shaft and used for displaying a swing angle, and the swing driving device 12 can be a speed reduction motor and drives the swing rotating shaft to rotate through a synchronous belt; the upper end of the swing arm 14 is fixedly connected with a swing rotating shaft, and the upper end of the pendulum bob suspender 15 is hinged on the swing rotating shaft; the pendulum 16 is arranged at the lower end of the pendulum suspension rod 15, the lower end of the swing arm 14 is provided with an electromagnet 17, and the electromagnet 17 is used for adsorbing the pendulum 16.

The stopping component comprises a stopping carrier plate 21, a guide seat 22, a buffer seat 23, a sliding seat 24 and a stopping driving device 25; the stop support plate 21 is fixedly connected with the lifting support plate 11 through a support plate suspender 20, so that the stop assembly can synchronously lift along with the pendulum mechanism; the guide seat 22 and the buffer seat 23 are both arranged on the stop support plate 21, two ends of the sliding seat 24 are respectively in sliding fit with one guide seat 22, the buffer seat 23 is provided with a spring and a guide rod part, and the middle part of the sliding seat 24 is matched with the spring and the guide rod part; the stopping driving device 25 is arranged on the sliding seat 24, a telescopic stop lever is arranged on the stopping driving device 25, and the lower end of the pendulum suspension rod 15 penetrates through the pendulum 16 and is matched with the telescopic stop lever of the stopping driving device 25.
