Wheel machining equipment

Wheel machining equipment, comprising a lathe bed, a plurality of first guide rails, a first servo motor, a first servo moving unit, a first spindle unit, a first-stage chuck, a plurality of radial positioning blocks, a plurality of first end-face positioning blocks, a plurality of first swing clamp cylinder pressure claws, a first servo feed system, a first tool turret, a plurality of second guide rails, a second servo motor, a second servo moving unit, a second spindle unit, a second-stage chuck, a mandrel base, a mandrel, a plurality of second end-face positioning blocks, a plurality of second swing clamp cylinder pressure claws, a second servo feed system and a second tool turret, wherein

• the first servo motor, the first guide rails and the first servo moving unit are installed on a left side of the lathe bed, and the first servo moving unit is driven by the first servo motor to horizontally move along the first guide rails;
• the first servo moving unit is provided with the first spindle unit, an output end of the first spindle unit is provided with the first-stage chuck, and the rotation of the first-stage chuck is controlled by the first spindle unit;
• the first servo feed system is installed at the top of the lathe bed, the first servo feed system comprises two axes, and the first tool turret is controlled by the first servo feed system to feed, so as to realize linkage turning and interpolation movement of the two axes;
• the first spindle unit is arranged to drive a wheel to rotate to complete the first-stage turning of the wheel;
• the second servo motor, the second guide rails and the second servo moving unit are installed on a right side of the lathe bed, and the second servo moving unit is driven by the second servo motor to horizontally move along the second guide rails;
• the second servo moving unit is provided with the second spindle unit, an output end of the second spindle unit is provided with the second-stage chuck, and the rotation of the second-stage chuck is controlled by the second spindle unit;
• the mandrel base is arranged at a center of the second-stage chuck, and the mandrel is arranged on the mandrel base;
• the second servo feed system is installed on a bottom of the lathe bed, the second servo feed system comprises two axes, and the second tool turret is controlled by the second servo feed system to feed, so as to realize linkage turning and interpolation movement of the two axes;
• the second spindle unit is arranged to drive the wheel to rotate to complete the second-stage turning of the wheel;
• a path of the first servo moving unit horizontally moving along the first guide rails is defined as a Q1 axis, and the path of the second servo moving unit horizontally moving along the second guide rails is defined as a Q2 axis;
• after the first-stage turning of the wheel is completed, the first servo moving unit is arranged to be driven by the first servo motor to do horizontal rightward movement along the Q1 axis until horizontally pushing the wheel to an appropriate position, the second servo moving unit is arranged to be driven by the second servo motor to do horizontal leftward movement along the Q2 axis to meet the wheel, when the plurality of second end-face positioning blocks on the second-stage chuck make contact with a wheel rim on an inner side of the wheel, the second servo moving unit stops moving, then the second swing clamp cylinder pressure claws are activated and clamp the wheel on the second-stage chuck, then the first swing clamp cylinder pressure claws release the wheel, and the first-stage chuck is withdrawn and restored to the original position, thus completing the connection of the first-stage turning and the second-stage turning.
