Abstract

Battery pack powered roll groover described herein includes a housing, an inner roller provided on the housing and configured to be received in an inner circumference of a workpiece, a groove roll provided on the housing and configured to produce a groove on the workpiece, one or more motors provided within the housing and configured to drive the groove roll, and an electronic processor electrically connected to the one or more motors. The electronic processor is configured to operate the one or more motors to perform a first operation of moving the groove roll in a radial direction, and operate the one or more motors to perform a second operation of moving the groove roll around a track in a circumferential direction. The first operation is performed to adjust a groove depth on the workpiece. The second operation is performed to produce the groove on the workpiece.

Claims18

Dependent claims

A roll groover comprising:

a housing;
an inner roller provided on the housing and configured to be received in an inner circumference of a workpiece;
a groove roll provided on the housing and configured to produce a groove on the workpiece;
one or more motors provided within the housing and configured to drive the groove roll;
an electronic processor electrically connected to the one or more motors, the electronic processor configured to:
control the one or more motors to move the groove roll around the workpiece while measuring distance,
determine whether the groove roll has traveled a first predetermined distance around a circumference of the workpiece,
determine whether the groove roll is below a second predetermined distance of a final depth when the groove roll has traveled the first predetermined distance,
in response to the groove roll not being below the second predetermined distance of the final depth, control the one or more motors to increase groove depth by a predetermined increment;
and
in response to the groove roll being below the second predetermined distance of the final depth:
control the one or more motors to increase groove depth by a fractional increment,
control the one or more motors to move the groove roll around the workpiece,
determine whether the groove roll is at an initial position, and
control the one or more motors to stop and indicate completion of operation when the groove roll is at the initial position.

A method of operating a roll groover including an inner roller configured to be received in an inner circumference of a workpiece and a groove roll configured to produce a groove on the workpiece, the method comprising:

operating, using an electronic processor, one or more motors to perform a first operation of moving the groove roll in a radial direction, wherein the first operation is performed to adjust a groove depth on the workpiece;
operating, using the electronic processor, the one or more motors to perform a second operation of moving the groove roll in a circumferential direction, wherein the second operation is performed to produce the groove on the workpiece;
and
providing, using a battery pack, power to the one or more motors.
