The present invention discloses a combined wheel burr removing device, which comprises a brush lifting system, a brush driving system, roller bed parts and a clamping rotating part. When the device is used, round brushes, rolling brushes and a plurality of brush bundles can rotate respectively, so that burrs on the back cavity of a wheel can be effectively removed in different directions, and the problem that the linear speed is low in the center but high at the outer edge when an integrated brush rotates at the same angular speed can be avoided; meanwhile, the device has the characteristics of high automation degree, advanced process, simple structure and high safety and stability.
