Automatic production line for machining hydraulic shell

The invention discloses a hydraulic shell machining automatic production line which comprises a first lathe used for machining threaded holes in the upper portion of a hydraulic shell and a second lathe used for machining threaded holes in the end portion of the hydraulic shell and further comprises a feeding machine used for feeding and discharging hydraulic shell blanks. The mechanical arm is used for moving and transferring the hydraulic shell; the placing table is used for positioning, overturning and temporarily storing the hydraulic shell; the cleaning table comprises a rotating part, an air blowing piece is arranged on the rotating part, and the air blowing piece conducts air blowing cleaning on the upper threaded hole and the end threaded hole under the rapid rotation of the rotating part; and the rinsing water tank is used for rinsing scrap iron on the surface of the hydraulic shell, and after rinsing is completed, the mechanical arm moves the hydraulic shell to the feeding machine for discharging.
