Comb brush rod vibration mode test bench

The utility model discloses a comb brush rod vibration mode test bench. The device comprises a rack, a transmission device, clamping devices and a connecting device, the transmission device is installed on one side of the bottom of the rack, one end of the transmission device is connected with a trapezoidal table, third guide rails are connected to the two sides of the inclined face of the trapezoidal table, idler wheels are connected into the third guide rails in a rolling mode, and the clamping devices are connected to the two sides of the top of the trapezoidal table. The comb brush rod vibration mode test bench can vibrate in the horizontal direction and the vertical direction, and can vibrate in the horizontal direction and the vertical direction at the same time, so that the test time can be greatly reduced, and test resources are saved. The whole test bed converts horizontal vibration into vertical vibration through a slider-crank structure, so that the whole space of the test bed is greatly reduced. 本
