Material transferring and positioning device for wheel machining center

A material transferring and positioning device for a wheel machining center comprising a base plate, a base, a first bearing, a first shaft sleeve, a hydraulic cylinder brake, a rotary cylinder, a cap, a second shaft sleeve, a second bearing, a sleeve, contacts, first linear bearings, springs, a synchronous cam, an end cap, a rotating shaft, a conical support, guide shafts, a bearing seat, second linear bearings, a mount, a connecting plate, a mounting plate and a cylinder, the material transferring and positioning device for a wheel machining center is provided with a high-precision centering mechanism and a circumferentially automatic adjusting mechanism;

• in the high-precision centering mechanism, the hydraulic cylinder brake, the rotary cylinder, the sleeve and the second shaft sleeve are installed on the first shaft sleeve;
• the second bearing and the rotating shaft are enclosed in the second shaft sleeve by the end cap, and two ends of the rotating shaft are respectively connected to output shaft of the rotary cylinder and the synchronous cam;
• the three or more first linear bearings are uniformly installed in side wall of the sleeve;
• three or more uniform curved surfaces are provided in side wall of the synchronous cam;
• outer end of each of the three or more contacts is provided with one of the springs and the first linear bearings, and inner ends of the three or more contacts are respectively connected to the same number of arcs of the high-precision synchronous cams;
• two ends of each of the springs are respectively in contact with one of the first linear bearings and axial end surface of one of the contacts, and the springs always have elastic force, so that inner ends of the contacts are always pressed against the synchronous cam;
• in the circumferentially automatic adjusting mechanism, the base and the mount are fixed on the base plate;
• the first shaft sleeve is installed in the base by the first bearing and the cap;
• the cylinder is installed in the mount by the mounting plate;
• output shaft of the cylinder is connected to the connecting plate;
• the two symmetrical second linear bearings are installed in the mount by the bearing seat;
• each of the two guide shafts is provided with one of the second linear bearings;
• upper ends of the two guide shafts are connected to the conical support, and lower ends thereof are connected to the connecting plate.
