Embodiments disclosed herein generally relate to a pivotable clamp or vise. For example, the vise may clamp or secure a workpiece at a suitable position and/or orientation.

A vise jaw combination used with a milling machine vise to hold a work-piece having either parallel edges or non-parallel edges. Wherein, the milling machine vise in this application disposes at least one movable member having threaded holes cooperating with fasteners to join the movable member and the vise jaw combination comprising a vertical axis tool post and a rotatable vise jaw. Wherein, the vertical axis tool post comprises a detachable wall disposing correlative thru holes for cooperating with the threaded holes and fasteners disposed at the movable member, whereby the vertical axis tool post is joined to the movable member disposed at the milling machine vise. Wherein, the rotatable vise jaw consists of a one-piece structure disposing a thru hole for receiving a vertical shaft disposed at the vertical axis tool post, whereby the rotatable vise jaw is joined to the vertical axis tool post.

Wherein, the milling machine vise in this application disposes at least one movable member having threaded holes cooperating with fasteners to join the movable member and the vise jaw combination comprising a vertical axis tool post, a horizontal axis tool post, and a rotatable vise jaw. Wherein, the vertical axis tool post comprises a detachable wall disposing correlative thru holes for cooperating with the threaded holes and fasteners disposed at the movable member, whereby the vertical axis tool post is joined to the movable member disposed at the milling machine vise. Wherein, the horizontal axis tool post comprises a rectangular base disposing a thru hole for receiving a vertical shaft disposed at the vertical axis tool post, whereby the horizontal axis tool post is joined to the vertical axis tool post. Wherein, the rotatable vise jaw consists of a one-piece structure disposing a thru hole for receiving a horizontal shaft disposed at the horizontal axis tool post, whereby the rotatable vise jaw is joined to the horizontal axis tool post.

The invention relates to vise pivotal jaws for holding irregular shaped objects and that are modular to work on various sized prior art vises. Also relates to pivotal jaws having aid to return back to a neutral center position. The design allows ease of disassembly for cleaning and reassembly.

Rotating vise jaws comprising first, second, third, and forth elements used with a milling machine vise to hold objects having either parallel or nonparallel edges. Wherein, said first element consists of a vertical axis tool post adapted to fit either a movable or stationary wall disposed at a milling machine vise. Said vertical axis tool post disposes a cylindrical shaft defining a vertical axis for cooperating with said second element comprising a vertical axis vise jaw having beveled side walls and a correlative through hole for cooperating with said vertical axis. Thus, said vertical axis tool post is attached to a milling machine vise and said vertical axis vise jaw is connected to said vertical axis, thereby providing a self-aligning vise jaw with a reversible clamping face; wherein said vise jaw is rotatable about a vertical axis for holding objects having either parallel or nonparallel edges.

Wherein, said third element consists of a horizontal axis tool post having a correlative through hole for connecting said horizontal axis tool post to said vertical axis. said horizontal axis tool post disposes a cylindrical shaft defining a horizontal axis for cooperating with said forth element comprising a horizontal axis vise jaw having beveled side walls and a correlative through hole for cooperating with said horizontal axis. Thus, said vertical axis tool post is attached to a milling machine vise, said horizontal axis tool post is connected to said vertical axis, said horizontal axis vise jaw is connected to said horizontal axis, thereby providing a self-aligning vise jaw with a reversible clamping face, wherein said vise jaw is rotatable about a horizontal axis for holding objects having either parallel or nonparallel edges.

A stop device having a L shaped mounting bracket secured to a machine vise by a mounting bracket screw, a stop arm having an elongated slot extended within the stop arm and running in a parallel direction to a length of the stop arm, a pivot clamp and pivot clamp screw connected to the elongated slot and attaching the stop arm to the mounting bracket along a length side of a machine vise, the stop arm moveable in both an Y and Z direction and lockable by the pivot clamp, a fixed jaw located at the second end of the stop arm and a stop clamp attached to the second end of the stop arm by stop clamp screw, the stop clamp including an adjustable jaw facing the fixed jaw of the stop arm with the stop clamp screw enabling changes to a distance between the jaws to allow the jaws to hold and support a portion of a stop rod having varying shapes and sizes in a fixed, deform-free condition therebetween.

The invention relates to vise pivotal jaws for holding irregular shaped objects that are removable and modular to work on other prior art vises. The design allows ease of disassembly for cleaning and reassembly.
