Abstract
Systems and devices for cutting annular objects comprising a structure built from t-slot profiles and clamping devices where an vertically adjustable t-slot profile is connected with a cutting assembly comprising a worm gear that turns a cutting blade that cuts into an annular object, and drive wheels that turn the annular object at a much slower rate than the spinning rate of the cutting blade.
Claims12
Systems and devices for moveably clamping and easily unclamping t-slot profiles comprising:
- two parallel t-slots profiles wherein each t-slot profile is comprised of metal forming at least one slot running the length of each parallel t-slot profile,
- an adjustable t-slot profile with a clamping device at one end and an extrusion at the other end, wherein the adjustable t-slot profile is perpendicular to the two parallel t-slot profiles, and wherein the clamping assembly connects one end of the adjustable t-slot profile with a first parallel t-slot profile and the extrusion connects the other end of the adjustable t-slot profile to a second parallel t-slot profile,
- wherein one end of the clamping device snugly fits in a cavity within the adjustable t-slot profile, and
- wherein said extrusion is sized to moveably slid in the slot of a second parallel t-slot profile and is in moveably connection with the slot in the second parallel t-slot profile;
- the clamping device is comprised of the assembly which is comprised of an elevator and bushing tightly sandwiched between guides, a cam rod running through the elevator and guides, wherein the cam rod has a pocket that is positioned relative to the bushing within the elevator, and wherein the assembly is sized to securely fit within the cavity in the adjustable t-slot profile;
- a linking rod connecting the elevator to a locking foot sized to moveably fit within the slot of the first parallel t-slot profile, wherein when unclamped the locking foot is capable of moveably sliding inside the t-slot;
- the cam rod is connected with a handle, wherein manipulating the handle will move the cam rod, and thereby move the pocket relative to the bushing, lifting the elevator, linking rod and locking foot, compressing and securely clamping the locking foot to an inside surface of the slot in the first parallel t-slot profile, thereby clamping the adjustable t-slot profile at a specific distance along and perpendicular to, the two parallel t-slot profiles.
The device of claim 8 wherein two parallel t-slot profiles are horizontal with a front end and a back end with a support platform suspended between the horizontal t-slot profiles,
- wherein the back end is connected via a clamping device with a first adjustable t-slot profile and rear fence so that the first adjustable t-slot profile travels in a horizontal direction, and
- wherein the front end is connected with a second set of parallel t-slot profiles that are vertical, and wherein a second adjustable t-slot profile is connected with, and perpendicular to, the vertical parallel t-slot profiles so that the second adjustable t-slot profile travels in a vertical direction, and wherein said second adjustable t-slot profile is connected with a cutting assembly.
The device of claim 9 wherein the cutting assembly is comprised of a drive shaft connected with an angled dual-thread worm gear disposed between two gears so that the top threads of the worm gear engage with one gear and the bottom threads of the worm gear engage with the second gear resulting in both gear spinning in the same direction;
- a plurality of drive wheels where each gear is directly connected with a drive wheel,
- a hypoid gear at the bottom of the worm gear that connects a cutting blade to the worm gear so that the gears, drive wheels and cutting blade are in parallel with each other and spin simultaneously when power is supplied via the power source,
- a clutch assembly comprised of at least one spring, a clutch wheel housing and a plurality of clutch wheels, and connected with the second adjustable t-slot profile so that both the clutch assembly and cutting assembly move simultaneously when the second adjustable t-slot profile is raised or lowered, and wherein said clutch wheels are lower than the cutting blade.
