Automatic wheel rim positioning and clamping tool

An automatic wheel rim positioning and clamping tool adapted for positioning and clamping a wheel rim for enabling a cutting tool to be operated to process said wheel rim, the automatic wheel rim positioning and clamping tool comprising:

• a base comprising a bottom wall for mounting, a top bearing wall opposite to said bottom wall, a center portion in communication between said bottom wall and said top bearing wall;
• an upright post mounted on said top bearing wall of said base above said center portion;
• a lateral chip conveyor comprising an annular fluid nozzle holder fixedly mounted on said top bearing wall of said base around said upright post for guiding in a fluid for flushing away chips, and a plurality of first lateral nozzles mounted on the periphery of said annular fluid nozzle holder for spraying out the fluid guided into said annular fluid nozzle holder;
• a vertical hydraulic chuck concentrically mounted on said upright post and affixed to said annular fluid nozzle holder, said vertical hydraulic chuck comprising a plurality of claw blocks equiangularly arranged on a top surface thereof and horizontally radially movable toward or away from said upright post;
• a positioning gripper comprising a plurality of gripper blocks respectively fixedly mounted on said claw blocks, each said gripper block having a friction surface located on one lateral side thereof and adapted for abutting against a bore wall of a center bore of the wheel rim to be processed;
• a plurality of air leakage detection units mounted on said top bearing wall of said base, each said air leakage detection unit comprising a contact surface for abutment against the wheel rim to be processed, a gas flow sensor mounted therein and a first air hole defined therein, said first air hole having one end thereof extended to said contact surface and an opposite end thereof connected to said gas flow sensor;
• and a plurality of clamping devices mounted on said top bearing wall of said base and spaced around said lateral chip conveyor and adapted for clamping the wheel rim to be processed.
