Abstract
A pulling tool comprises an air-powered internal anvil and hammer. The pulling tool is attached to the object to be removed. The hammer is urged by pressurized air to repeatedly strike the anvil, which applies a percussive force to the object, progressively removing the object from its housing. A conventional air hammer can be modified into a tool puller by replacing the air hammer bit with a cap, and attaching the object to the rear of the air hammer through a coupler. Alternatively, a cylindrically-shaped collar is slidably secured over a conventional air hammer. A pulling bit slidably communicates with a flanged rod attached to the object to be removed. Operation of the air hammer causes the pulling bit to strike the flange, progressively removing the object from its housing.
Claims18
A kit for converting an air hammer into a tool for removing a friction-fit or press-fit component from a seat, the air hammer comprising a body and a reciprocating member, the kit comprising:
- a pull rod adapted to be attached to the component;
- and
- a pulling member adapted to be operably interconnected with a forwardly-directed percussive force generated by the air hammer and adapted to percussively communicate with the pull rod interconnected with a component located rearwardly of the air hammer.
A hand-held, pneumatically-driven hammer, comprising:
- a body having a mounting portion at a rear portion of the hammer, the mounting portion being adapted to fixedly couple a component thereto, the component being frictionally retained in a component seat;
- whereby the hammer is thereby adapted to convert the hammer into a tool puller for removing the component from the component seat.
