Abstract
A cutting head assembly for use in cutting plate glass has a simplified drive train, all positioned about the vertical rotational centerline. The drive train includes a hollow bore drive motor having a drive adaptor directly engaged with a spline shaft that extends through the hollow bore. The lower end of the spline shaft is directly engaged with a cutting tool holder for retaining a cutting tool. The drive motor imparts rotational movement to the cutting tool through the spline shaft and the cylinder imparts vertical movement to the cutting tool by vertical movement of the spline shaft.
Claims13
A cutting head assembly, for use in cutting glass plate while following a predetermined path generally created by a controller, comprising, in combination:
- a drive motor having a hollow bore extending through the motor about the vertical rotational centerline of the motor;
- a spline shaft positioned in the bore, said spline shaft having a first end extended above the motor and a second end extended below the motor;
- a cutting tool removably attached to the second end of the spline shaft;
- and a cylinder and piston arrangement attached to the first end of the spline shaft, wherein the drive motor imparts rotational movement to the cutting tool through the spline shaft and the cylinder and piston arrangement provides movement in the vertical direction to the cutting tool through the spline shaft which moves vertically through the hollow bore of the drive motor.
