Abstract: A device for removing circumferential burrs of a wheel with high precision includes an electric cylinder, a lifting table, guide rails, an electric cylinder, a sliding block, a plurality of sensors, a rim burr cutter, a riser burr cutter, and the like. The device can simultaneously remove circumferential burrs from the flange edge, the outer rim and the riser slot edge, which eliminates the error caused by coaxial degree deviation, so that the rotating center of the cutters coincides with the circumferential center of the burrs. The device is configured to provide high-precision removal of burrs from the flange edge, and high-precision removal of burrs from the outer rim and the riser.

Abstract: The present application discloses a device for trimming the positioning end surface of a wheel blank comprises a wheel positioning clamping system, an axial positioning surface trimming system and a radial positioning surface trimming system. The wheel positioning clamping system completes the loading, clamping and low-speed rotation of the wheel; the axial positioning surface trimming system firstly completes the detection of the wheel axial hop, and then completes the trimming of the axially positioning surface; the radial positioning surface trimming system firstly completes the detection of the wheel radial hop, and then completes the trimming of the radial positioning surface. The axially positioning surface trimming system and the radial positioning surface trimming system are independent of each other and complementary to each other, and the two systems accomplish the trimming of the positioning end surface of the wheel blank jointly.
