Abstract

At least one resurfacing system and at least one adjustment guide system for positioning a chuck holding a watch component relative to the resurfacing system. In example embodiments, the adjustment guide system includes one guide rail providing linear offset/distance and angular adjustment and guidance, or two perpendicular guide rails providing linear offset/distance and lateral position adjustment and guidance. Some embodiments include first and second resurfacing systems and a common rotary drive system that drives both the first and second resurfacing systems. The first resurfacing system can be a linear belt resurfacing system and the second resurfacing system can be a rotary disc resurfacing system. Some embodiments including the rotary disc resurfacing system have a metal rotary mounting disc driven by the drive system and a replaceable magnetic resurfacing disc that magnetically adheres to the rotary disc. Also disclosed is a method of resurfacing watches using these watch resurfacing devices.

Dependent claims

A device for resurfacing a watch component on a chuck, the device comprising:

a first resurfacing system comprising a first rotary drive member and a first resurfacing element that is driven through a first operating motion by the first rotary drive member and against which the watch component can be contacted for resurfacing;
a second resurfacing system comprising a second rotary drive member and a second resurfacing element that is driven through a second operating motion by the first rotary drive member and against which the watch component can be contacted for resurfacing;
a common drive system comprising a connecting member and an actuator operably connected to the connecting member, wherein the connecting member extends between and operably connects the first and second rotary drive members so that operation of the actuator rotationally drives both the first and second rotary drive members to drive both the first and second resurfacing elements through their respective operating motions;
a first adjustment guide system comprising a first offset guide rail that is positioned offset relative to the first resurfacing element and that supports and guides the chuck to enable the watch component on the chuck to be positioned offset relative to the first resurfacing element during use;
and
a second adjustment guide system comprising a second offset guide rail that supports and guides the chuck to enable the watch component on the chuck to be positioned offset relative to the second resurfacing element during use,
wherein the first adjustment guide system includes a lateral guide rail that is transverse to the first offset guide rail to enable the watch component held by the chuck to be positioned laterally relative to the first resurfacing element during use, and
wherein the second resurfacing system is a rotary disc resurfacing system further comprising a metal rotary mounting disc driven by the second rotary drive member, wherein the second resurfacing element is a replaceable resurfacing disc comprising a magnetic back layer and a resurfacing front layer, wherein the replaceable resurfacing disc is magnetically adhered in place during use and is manually removable for replacement after use.

A device for resurfacing a metallic component of a watch held by a chuck having support feet, the device comprising:

a first linear belt resurfacing system comprising a drive roller, a free roller, and a resurfacing belt looped around the drive and free rollers, driven through a linear operating motion by the drive roller, and against which the metallic watch component can be contacted for resurfacing;
a second rotary disc resurfacing system comprising a drive flange, a mounting disc driven by the drive flange, and a replaceable resurfacing disc removably mounted to the mounting disc, driven through a rotary operating motion by the drive flange, and against which the metallic watch component can be contacted for resurfacing, wherein the resurfacing disc is perpendicular to the resurfacing belt, wherein the mounting disc is metal, the resurfacing disc includes a magnetic back layer and a resurfacing front layer, wherein the magnetic back layer removably adheres the resurfacing disc to the metal mounting disc during use and permits manually removal and replacement of the resurfacing disc after use,
a common drive system comprising a connecting member and a rotary motor operably connected to the connecting member, wherein the connecting member extends between and operably connects the drive roller and flange together so that operation of the motor rotationally drives both the drive roller and flange to drive both the resurfacing belt and disc through their respective operating motions;
a first adjustment guide system comprising a base plate, a guide plate positioned and laterally sliding on the base plate, a lateral guide rail slidingly engaged between the base plate and the guide plate to guide the lateral sliding of the guide plate on the base plate, and a first offset guide rail extending upwardly from the guide plate and perpendicularly to the resurfacing belt, wherein the offset guide rail supports and guides the chuck to enable the metallic watch component on the chuck to be positioned offset relative to the resurfacing belt during use, and wherein the lateral guide rail enables the metallic watch component on the chuck to be positioned laterally relative to the resurfacing belt during use;
a second adjustment guide system comprising a second offset guide rail extending perpendicularly to the resurfacing disc, wherein the second offset guide rail supports and guides the chuck to enable the metallic watch component on the chuck to be positioned offset relative to the second resurfacing element during use;
and
a frame to which the first linear belt resurfacing system, the second rotary disc resurfacing system, the first adjustment guide system, the second adjustment guide system, and the common drive system are mounted, wherein the frame comprises a guide opening that removably receives the second offset guide rail during use, wherein the second offset guide rail is removably mounted to the frame so that it can be installed into the guide opening during use and removed from the guide opening when not in use to provide clearance and avoid being an obstruction.
