The subject matter disclosed herein relates generally to a work holding device, such as a vise, and, more particularly, to a portable work holding device configured to removably mount to a support, for example, a vehicle receiver hitch or a support surface, such as a table or work bench.
Attempts have been made in the past to attach a vise to work trucks or vehicles by taking an existing bench vise and mounting the bench vise to a platform or a pad on the vehicle. While this creates a work holding device, the conventional bench vise is not designed to be portable and, as such, is heavy and difficult to transport. Other attempts to make work holding devices more portable have resulted in a work holding device that compromises the work holding capabilities of a conventional bench vise. In both of these cases, an undesirable tradeoff is made for either portability or for function.
In one aspect, a work holding device includes a first jaw piece having an elongated first connection member for connecting the work holding device to a support. The first connection member defines a first passage. A second jaw piece has an elongated second connection member positionable within the first passage. The second connection member defines a second passage in communication with the first passage. A spindle assembly movably connects the second jaw piece to the first jaw piece. The spindle assembly is configured to move the second jaw piece with respect to the first jaw piece to create a clamping pressure when an object is placed between the first jaw piece and the second jaw piece.
In another aspect, a portable work holding device includes a stationary first jaw piece having a casting and an elongated first connection member extending from the casting. The first connection member defines a first passage. A movable second jaw piece has an elongated second connection member extending from the second jaw piece. The second connection member is positionable within the first passage to couple the second jaw piece to the first jaw piece. The second connection member defines a second passage in communication with the first passage with the second connection member positioned within the first passage. A spindle assembly movably couples the second jaw piece to the first jaw piece. The spindle assembly includes a spindle nut positioned within at least the first passage. The spindle nut forms a helical thread on an inner surface of the spindle nut along at least a portion of a length of the spindle nut between a first end and a second end of the spindle nut. A spindle forms a helical thread on an outer surface of the spindle along at least a portion of a length of the spindle that cooperates with the helical thread formed on the inner surface of the spindle nut to facilitate translation of the second jaw piece with respect to the first jaw piece along an axis defined by the spindle.
In yet another aspect, a portable work holding device assembly includes a work holding device and a plate assembly. The work holding device includes a first jaw piece having an elongated connection member for connecting the work holding device to a support, a second jaw piece, and a spindle assembly movably connecting the second jaw piece to the first jaw piece. The spindle assembly includes a threaded spindle rotatable to move the second jaw piece with respect to the first jaw piece. The plate assembly includes a member having a plurality of walls defining a passage with a complementary cross-section to receive the first connection member. One or more brackets are coupled to a corresponding wall of the plurality of walls of the member. The one or more brackets each define one or more apertures to facilitate coupling the work holding device to a support surface.
In yet another aspect, a method of assembling a work holding device includes providing a stationary first jaw piece having a casting and an elongated first connection member extending from the casting, wherein the first connection member defines a first passage. An elongated second connection member of a movable second jaw piece is positioned within the first passage. The second connection member defines a second passage in communication with the first passage. A spindle assembly is positioned within the first passage and the second passage to movably couple the second jaw piece to the first jaw piece.
The embodiments described herein relate to a work holding device, such as a vise, that is capable of being quickly mounted to a vehicle using the vehicle receiver hitch as a connection point. The work holding device can also be mounted to a bracket that is fixed to a suitable support surface, such as a table or a work bench, utilizing an elongated connection member also used for mounting the work holding device to the vehicle receiver hitch. In one embodiment, the work holding device includes a fixed or stationary jaw piece, that includes a casting and the elongated connection member, and a movable jaw piece that is operatively connected to the stationary jaw piece by a spindle assembly that moves the movable jaw piece with respect to the stationary jaw piece to generate or create a pressure when an object is paced between the stationary jaw piece and the movable jaw piece. In one embodiment, the work holding device includes a handle having a single fixed arm that can be fixed or locked in a desired position, for example, in a twelve o'clock position, for storing the work holding device on the vehicle while the vehicle is being driven. In one embodiment, a recess is formed in the casting of the stationary jaw piece that allows for weight reduction, as well as a handle feature to facilitate portability. A work surface or an anvil is formed on at least the stationary jaw piece and is raised above the jaw pieces to create a more useable work surface while the work holding device is mounted to the vehicle.
