Wheel bolt hole chamfer device

A wheel bolt hole chamfer device, being composed of a base, a support frame, a lower servo motor, a first shaft, bearing seats, a turntable, five stop blocks, five pairs of guide rails, strong springs, five sliding blocks, a cylinder, a guide post, a lifting table, an upper servo motor, a second shaft, a driving friction wheel, driven shafts, driven friction wheels, chamfer cutters, a left feeding cylinder, a right feeding cylinder, vertical guide posts, a feeding platform, corner cylinder pressure claws, axial positioning blocks and radial positioning blocks;

• wherein:
• the five stop blocks and the five pairs of guide rails are uniformly distributed about a center of the turntable, the five stop blocks and the five pairs of guide rails being all fixed on the turntable, the five sliding blocks being respectively mounted on the five pairs of guide rails, and the five sliding blocks being connected with the five stop blocks via the strong springs;
• the cylinder and the guide post being fixedly mounted in the center of the turntable, an output end of the cylinder being connected with the lifting table to control up-down motion of the lifting table, the upper servo motor being fixed on the lifting table, an output end of the upper servo motor being connected with the second shaft, and the driving friction wheel being conical and mounted on the second shaft;
• a driven shaft of the driven shafts being mounted on each sliding block of the five sliding blocks, a driven friction wheel of the driven friction wheels being mounted on the driven shaft, the driven friction wheels being inversely conical and matched with the driving friction wheel, and a chamfer cutter of the chamfer cutters being mounted at a top of each driven shaft of the driven shafts;
• the cylinder driving the lifting table to move up, the driving friction wheel being able to be driven to move up, and pitch diameters of the chamfer cutters being able to be adjusted via taper fit of the driving friction wheel and the driven friction wheels;
• the upper servo motor being started to drive the driving friction wheel to rotate, and the chamfer cutters being able to rotate via fit of the driving friction wheel and the driven friction wheels;
• and the pitch diameter adjustment and the rotating drive of the chamfer cutters being integrated.
