There is provided a clamping mechanism, including: a housing which is movable to clamp or unclamp an object having clamping blocks; a clamping plate disposed in front of the housing; and a first elastic member applying a clamping force to the clamping plate by movement of the housing, wherein the clamping blocks have receiving grooves in which edges of the clamping plate are received.

A vise having a modular construction that allows for ease of manufacture, assembly, and changeover or replacement of wear items, such as gripping surfaces of jaws of the vise. The modular construction also provides for reduced weight of the vise compared to conventional cast type vises. The vise also incorporates quick adjustment features allowing for the vise to be easily rotated, a position and size of an opening of the jaws to be rapidly adjusted, and a clamping force applied with ease.

A clamping apparatus includes a spindle body and a nut element to be screwed together for decreasing a spacing between first and second clamping elements to clamp an object disposed therebetween. The nut element has roller bodies with a defined roller engagement structure axially rotatably secured on a receiving body of the nut element and distributed in circumferential direction. A plurality of engagement regions distributed and/or spaced apart on the spindle body each have one spindle body engagement structure. The roller engagement structures of the roller bodies engage or can engage the spindle body engagement structures of the spindle body. The nut element can be screwed to the spindle body by the mutually engaged engagement structures of the spindle body and of the roller bodies, in particular with rolling of the roller bodies on the spindle body. An apparatus and a vise having the clamping apparatus are also provided.

A fluid pressure vise actuator includes a housing and an inner bore of the housing. A piston is disposed in the housing, and the piston is configured to actuate based on a pressure increase in ports of the housing. A gear is also disposed in the inner bore of the housing, and a portion of the gear is adjacent to the piston such that an actuation of the piston is configured to rotate the gear. The gear includes a socket configured to interface with a vise and operate the vise based on a rotation of the gear. The housing also includes adjustable clamping blocks configured to engage with the vise to provide support for the housing during operation. An adjustment of the clamping blocks enables the fluid pressure vise actuator to interface with multiple types of existing vises.

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.

A work table apparatus is disclosed for supporting a ferromagnetic object, the work table apparatus including a table having a first side and a second side opposite the first side, the first side oriented to support the ferromagnetic object. A magnetic assembly can be positioned adjacent the second side of the table, the magnetic assembly configured to produce a magnetic field extending exterior to the magnetic assembly to secure a ferromagnetic object in a desired position on the table. The magnetic assembly can be configured to alternate between an active mode where the magnetic field is produced and an inactive mode wherein magnetic fields produced by the magnetic assembly are retained within the magnetic assembly.
