Automatic assembly equipment for air spring piston

According to the automatic assembling equipment for the air spring piston, a piston rod of a vertical oil cylinder stretches out and controls a material suction disc to move downwards, the material suction disc sucks a piston body placed on a material placing platform, the material suction disc and the piston body move upwards at the same time, and a piston rod of a displacement control air cylinder retracts and controls a transverse moving plate to move leftwards till the piston body is located over a discharging opening; the material suction disc and the piston bodies move downwards at the same time until the piston bodies can be oppositely clamped together through a first material clamping air cylinder and a second material clamping air cylinder, a piston rod of a vertical oil cylinder retracts again and controls the material suction disc to move upwards, and a piston rod of a displacement control air cylinder stretches out and controls a transverse moving plate to move rightwards till a torque wrench is l
