The invention discloses a groove type low-frequency vibration drilling workbench which comprises a driving motor, a lower box body, an upper box body, a rotary driving shaft, a linear bearing, a linear driving shaft and a platen. The upper end of the lower box body and the lower end of the upper box body are in butt connection through a fastening bolt. The left end and the right end of the rotary driving shaft are rotationally arranged on the left side and the right side of the lower box body and the upper box body respectively. The top of the upper box body is provided with the linear bearing with the lower end stretching into the upper box body. The linear driving shaft penetrates in the linear bearing in a sliding mode. The upper end of the linear driving shaft is fixedly connected with the lower surface of the platen. The lower portion of the linear driving shaft is provided with a fixing frame. A compression spring is arranged between the lower surface of the top of the lower box body and the fixing frame. The lower end of the linear driving shaft and the rotary driving shaft are in driving connection through a low-frequency vibration mechanism. According to the groove type low-frequency vibration drilling workbench, stepless adjustment for the vibration frequency can be achieved, the amplitude of low-frequency vibration can be adjusted, a set of available vibration drilling parameters can be conveniently found, and a to-be-machined part is machined.
