Automatic knocking device for filter performance test

The invention discloses an automatic knocking device for a filter performance test. The automatic knocking device comprises a supporting mechanism, a side face knocking assembly and a bottom face knocking assembly, the supporting mechanism is used for bearing a to-be-tested filter, and the side face knocking assembly is installed on the supporting mechanism and used for knocking the side face of the to-be-tested filter. The bottom surface knocking assembly is installed on the supporting mechanism and is used for knocking the bottom surface of the to-be-tested filter. Manual knocking is replaced by automatic knocking, the influence of human subjective factors can be avoided, the consistency of knocking force and the stability of knocking frequency are improved, knocking points are fixed, single-face knocking is replaced by multi-face knocking, the knocking test requirement is met, and the test effect is powerfully guaranteed. 本发明公开了一种用于滤波器性能测试的自动敲击装置。自动敲击装置包括支撑机构、侧面敲击组件和底面敲击组件，支撑机构用于承载待测试滤波器，侧面敲击组件安装于所述支撑机构且用于
