Abstract
A method of retaining a hammer tool in the front head of a powercell assembly of a hammer assembly includes biasing a hammer tool retaining pin such that a portion of the tool retaining pin extends into a tool receiving bore of the front head of the powercell assembly, holding a hammer tool in the tool receiving bore of the front head of the powercell assembly via the tool retaining pin, and releasing the hammer tool remotely from the hammer assembly.
Claims20
A tool retaining pin for use with a hammer assembly, the tool retaining pin comprising:
- a body defining a longitudinal axis;
- a forward tool retaining portion;
- and
- a rear tool retaining pin activation portion;
- wherein the forward tool retaining portion defines a first maximum dimension measured along a direction perpendicular to the longitudinal axis, and the rear tool pin activation portion defines a second maximum dimension measured along a direction perpendicular to the longitudinal axis that is greater than the first maximum dimension.
A powercell assembly for use with a hammer assembly, the power cell assembly comprising:
- a front head defining
- an exterior;
- a first bore defining a hammer tool movement axis and a first bore maximum dimension measured along a direction perpendicular to the hammer tool movement axis,
- a second bore defining a second bore maximum dimension measured along a direction parallel to the hammer tool movement axis, the second bore extending from the first bore along a second bore longitudinal axis that forms a first oblique angle with the hammer tool movement axis;
- a third bore defining a third bore maximum dimension measured along a direction parallel to the hammer tool movement axis, the third bore extending from the second bore along a third bore longitudinal axis that forms a second oblique angle with the hammer tool movement axis;
- wherein the third bore maximum dimension is greater than the second bore maximum dimension.
A method of retaining a hammer tool in the front head of a powercell assembly of a hammer assembly, the method comprising:
- biasing a hammer tool retaining pin such that a portion of the tool retaining pin extends into a tool receiving bore of the front head of the powercell assembly;
- holding a hammer tool in the tool receiving bore of the front head of the powercell assembly via the tool retaining pin;
- and
- releasing the hammer tool remotely from the hammer assembly.
