  • Patent number: 10933499
    Abstract: Disclosed is a wheel airtight rubber ring press-fitting device, consisting of a frame, first servo motors, ball screw pairs, first guide rails, a first cylinder and the like. The device may be used for automatic continuous production. The central axis of an airtight rubber ring coincides with the central axis of the outer rim of a wheel, so that the positioning precision is improved, and high-precision press-fitting is realized. Through cyclic switching of double manipulators, the press-fitting feeding time is nested, the press-fitting cycle is shortened, and the working efficiency is improved.
