8/339079

Inventors:

Henry R. Hardy - Osteen FL

International Classification:

B23P 1902

US Classification:

29251

Abstract:

A dental press apparatus for removing and installing a dental handpiece component includes a press having a frame and a driving member supported on the frame for pushing against items placed on the press. A jig is mounted in the press frame and has a base for supporting a dental handpiece thereon and has a push plate located above the base plate and slidably mounted for sliding towards the base plate responsive to actuation of the press to move the driving member against the push plate. The first ram member attaches to the jig push plate for removing a dental handpiece member and a second ram member is attached to the push plate and is used to install a bearing onto the dental handpiece turbine. The jig base plate and push plate are held together with rods having coil springs thereover and attached to the base plate and having the push plate sliding on the rod. The spindle ram has a countersunk hole for pin alignment and the other ram member has a passageway therethrough countersunk from one end for holding a coil spring which in turn supports a hollow plunger in the barrel portion to assist in aligning and positioning a bearing being attached to the dental handpiece.

Abstract:

A dental press apparatus for removing and installing a dental handpiece bearings includes a press having a frame having a base with a plurality of apertures therethrough for supporting a dental handpiece thereon and a push plate supported on the frame for pushing against items placed on the press. A spindle ram is attached to the push plate for removing the spindle in a dental handpiece turbine positioned on the base. A bearing ram is attached to the push plate for attaching a bearing to the dental handpiece turbine positioned on the base. A parts tray having an angled surface is removeably supported on the frame below the base for catching a turbine spindle passing through said base aperture after being removed from a dental handpiece turbine, so that a dental handpiece turbine bearing can be rapidly removed and replaced in press. The press includes a removable turbine chuck protector for the spindle ram. The frame has a plurality of suction cups and a drawer built thereinto to hold parts therein.
