Vise with magnet
A vise for securing a work piece is disclosed which includes a base. A first jaw piece and a second jaw piece can be disposed on the base, at least one of the first and second jaw pieces movable on the base such that the first and second jaw pieces are moveable toward and away from one another. A magnetic assembly can be positioned on the base and configured to produce a magnetic field that extends beyond the base to secure the vise to a magnetically permeable or ferromagnetic work surface. The magnetic assembly can be operable to alternate between an active mode and an inactive mode. The magnetic assembly can produce a magnetic field when the magnetic assembly is in the active mode to secure the vise to a magnetically permeable or ferromagnetic work surface.
1. A vise for securing a work piece, the vise comprising:
a base;
a first jaw piece and a second jaw piece disposed on the base, at least one of the first and second jaw pieces movable on the base such that the first and second jaw pieces are moveable toward and away from one another; and
a magnetic assembly positioned on the base, the magnetic assembly including a first permanent magnet and a second permanent magnet, the first permanent magnet rotatable relative to the second permanent magnet to alternate the magnetic assembly between an active mode and an inactive mode, wherein the magnetic assembly produces a magnetic field that extends exterior to the magnetic assembly when the magnetic assembly is in the active mode.
2. The vise of claim 1 , wherein
the magnetic assembly includes a magnetic assembly housing secured to the base;
the first permanent magnet is rotatably disposed on the magnetic assembly housing; and
the second permanent magnet is fixedly connected to the magnetic assembly housing, such that the first permanent magnet is rotatable on the magnetic assembly housing relative to the second permanent magnet.
3. The vise of claim 2 , wherein:
the first permanent magnet has a first north pole and an opposing first south pole;
the second permanent magnet has a second north pole and an opposing second south pole; and
the magnetic assembly is in an active mode when the first north pole of the first permanent magnet is oriented in the same direction as the second north pole of the second permanent magnet.
4. The vise of claim 3 , wherein the magnetic assembly is placed in an inactive mode when the first permanent magnet is rotated such that the first north pole on the first permanent magnetic and the second north pole of the second permanent magnet are oriented in opposite directions from one another.
5. The vise of claim 1 , further comprising an actuator connected to the first permanent magnet, the actuator being rotatable to rotate the first permanent magnet on the magnetic assembly to alternate the magnetic assembly between the active mode and the inactive mode.
6. The vise of claim 5 , wherein the actuator includes a lever arm configured to rotate the first permanent magnet through 180 degrees of rotation to reverse the polar orientation of the first permanent magnet.
7. The vise of claim 6 , wherein the base includes a bottom surface and lateral sides, and the lever arm extends outward from one of the lateral sides of the base.
8. The vise of claim 6 , wherein the base includes a top surface, and the lever arm extends outward from the top surface of the base.
9. The vise of claim 1 , wherein the magnetic assembly is positioned on a first side of the base and the first and second jaw pieces are located on an opposing second side of the base.
10. The vise of claim 1 , wherein:
the first jaw piece is fixed on the base; and
the vise further comprises a spindle rotatably mounted on the base and connected to the second jaw piece, wherein rotation of the spindle causes the second jaw piece to move relative to the first jaw piece.
11. The vise of claim 1 , wherein:
the base is substantially rectangular and has four corners; and
the vise further comprises four magnetic assemblies, each of the at least four magnetic assemblies positioned proximate to a corresponding corner of the base.
12. The vise of claim 1 , wherein the base has a bottom surface, and the magnetic assembly is positioned on the base such that the magnetic assembly is flush with the bottom surface of the base.
13. The vise of claim 1 , wherein the magnetic assembly produces a magnetic field that extends beyond the bottom surface of the base.
14. A vise for securing a work piece, the vise comprising:
a base having a first side and a second side;
a first jaw piece and a second jaw piece disposed on the base adjacent the first side of the base, at least one of the first and second jaw pieces movable on the base such that the first and second jaw pieces are moveable toward and away from one another; and
a plurality of magnetic assemblies located on and spaced from one another adjacent the second side of the base, each of the magnetic assemblies configured to produce a magnetic field beyond the second side of the base,
wherein the magnetic assemblies are operable to alternate between an active mode and an inactive mode, the magnetic assemblies producing a magnetic field that extends beyond a bottom surface of the base when the magnetic assembly is in the active mode.
15. The vise of claim 14 , wherein:
the magnetic assembly includes a first permanent magnet and second permanent magnet, the first permanent magnet rotatable relative to the second permanent magnet to alternate the magnetic assembly between the active mode and the inactive mode; and
when the magnetic assembly is in the inactive mode, the first and second permanent magnets are oriented such that the magnetic field produced by the first permanent magnet is attracted to and collapses into the second permanent magnet without extending beyond the base, and vice versa.
