Coating dipping device for automobile brake spring piece

The invention belongs to the technical field of automobile brake spring piece dipping, and particularly relates to an automobile brake spring piece coating dipping device which comprises a liquid storage tank, a discharging frame, an air cylinder, a fixing frame, a rotating frame, a torsion spring and the like. The discharging frame is connected to the liquid storage tank, the air cylinder is installed on the discharging frame, and the fixing frame is connected to a lifting rod of the air cylinder; the two sides of the fixing frame are rotationally connected with rotating frames, and torsion springs are connected between the rotating frames and the fixing frame. According to the device, the full gear rotates to drive the impregnated automobile brake spring piece to turn over by 180 degrees, then an extrusion block moves upwards to extrude an air bag, so that smearing liquid in the air bag is sprayed to the bottom of the automobile brake spring piece from a spraying hole for secondary spraying, the automobile
