Oil seal press-fitting equipment in steering gear shell and press-fitting technology thereof

The invention discloses oil seal press-fitting equipment in a steering gear shell and a press-fitting technology thereof. The press-fitting equipment comprises a press-fitting cylinder and a pressing head, wherein the pressing head is arranged on a piston rod of the press-fitting cylinder through a pressing rod; an oil seal positioning structure, which is matched with one face of an oil seal with an annular groove, is arranged on the end part of the pressing head. The press-fitting technology comprises the following steps that the bottom end of the steering gear shell is fixed on a shell positioning seat; an oil cylinder end opening of the steering gear shell faces upwards; the oil seal is arranged on the end part of the pressing head; when the press-fitting cylinder works, the pressing rod drives the pressing head and the oil seal to both press into an oil seal installation position in the steering gear shell; the pressing rod drives the pressing head to rotate and retreat from the steering gear shell, so that the oil seal press-fitting operation is finished. According to the oil seal press-fitting equipment in the steering gear shell and the press-fitting technology, the oil seal is correctly positioned through the oil seal positioning structure at the end part of the pressing head, so that the oil seal can be quickly installed in an oil cylinder, and the situation that the oil seal is installed reversely can be prevented.
