Inner hole sleeve pulling device

An inner hole sleeve pulling device comprises a cylindrical pulling base. The axis of the pulling base is in the longitudinal and horizontal directions, a cylindrical cavity is arranged in the middle of the front end surface of the pulling base, the outer side wall of the pulling base is fixedly connected to the inner ends of a plurality of pulling plates, the pulling plate are distributed on the circumference of the pulling base in a surrounded manner, the surface of each pulling plate extends outwardly and radially, and pulling bolts are rotationally installed on the surfaces of the pulling plates in the longitudinal and horizontal directions; a round press cover is fixed to the front end surface of the pulling base, a plurality of guide grooves are radially formed in the rear end surface of the press cover and are distributed surrounding the circumference of the press cover evenly, and limiting rods are arranged in the middle of the guide grooves in the longitudinal and horizontal directions and are fixed to the front end surface of the pulling base. According to the device, a liner, a sealing sleeve and a bearing outer ring in a blind hole can be disassembled efficiently and rapidly, and the relevant parts are prevented from damage.
