Abstract
The press tool includes a frame, an abutment part mounted to one end of the frame, and a lever actuated ram mounted to the other end of the frame. The ram includes a pair of interchangeable fittings (one for affixing the push nuts and one for removing the push nuts). Rocker plates pivotally connect the rams to a long lever, which extends and retracts the ram through a tubular sleeve mounted to the frame. The assembly fitting includes a magnet that holds a push nut to the ram. When the lever is depressed, the ram extends and the push nut is pressed axially onto the axle rod. The removal fitting has a two pronged head. When the lever is depressed, the prongs deform the push nut flange, which bends back the teeth that secure the push nut to the axle.
Claims20
An apparatus for affixing a push nut to an elongated axle rod of a wheeled rollout cart, where the push nut includes a cap for receiving the end of the axle rod, an annular flange extended around the cap and a tooth formed between the cap and the flange that restrictively engages the axle rod when pressed onto the axle rod, the apparatus comprising:
- a frame;
- an abutment part mounted to the frame;
- an extensible ram mounted to the frame for movement between an extended position and a retracted position, the ram spaced from the abutment part for receiving the axle rod axially between the abutment part and the ram, the ram includes a fitting mounted for receiving the push nut therein;
- and
- means operatively connected to the frame and ram for reciprocating the ram from the retracted position to the extended position to axially press the push nut received in the fitting onto the axle rod received between the abutment part and the ram.
An apparatus for removing a push nut from an elongated axle rod of a wheeled rollout cart, where the push nut includes a cap for receiving the end of the axle rod, an annular flange extended around the cap and a tooth formed between the cap and the flange that restrictively engages the axle rod when pressed onto the axle rod, the apparatus comprising:
- a frame;
- an abutment part mounted to the frame;
- an extensible ram mounted to the frame for movement between an extended position and a retracted position, the ram spaced from the abutment part for receiving the axle rod axially between the abutment part and the ram, the ram includes a fitting for contacting the flange of the push nut near the tooth;
- and
- means operatively connected to the frame and ram for reciprocating the ram from the retracted position to the extended position to forcibly deform the flange around the tooth of the push nut mounted to the axle rod received between the abutment part and ram and to bend the tooth away from the axle rod.
An apparatus for affixing a push nut to an elongated axle rod of a wheeled rollout cart and removing a push nut from an elongated axle rod of a wheeled rollout cart, where the push nut includes a cap for receiving the end of the axle rod, an annular flange extended around the cap and a tooth formed between the cap and the flange that restrictively engages the axle rod when pressed onto the axle rod, the apparatus comprising:
- a frame;
- an abutment part mounted to the frame;
- a first interchangeable fitting for receiving the push nut therein when the apparatus is used to affix the push nut to the axle rod;
- and a second interchangeable fitting for forcibly contacting the push nut mounted to the axle rod when the apparatus is used to remove the push nut from the axle rod;
- an extensible ram mounted to the frame for movement between an extended position and a retracted position, the ram spaced from the abutment part for receiving the axle rod axially between the abutment part and the ram, the extensible ram adapted to receive one of the first interchangeable fitting and a second interchangeable fitting;
- and
- means operatively connected to the frame and ram for reciprocating the ram from the retracted position to the extended position such that one of the first interchangeable fitting and the second interchangeable fitting engages the axle rod received between the abutment part and the ram whereby the first interchangeable fitting presses the push nut axially onto the axle rod when the first interchangeable fitting is received by the ram and the second interchangeable fitting forcibly deforms the flange around the tooth and bends the tooth away from the axle rod when the second interchangeable fitting is received by the ram.
