Abstract
Systems for cutting cylindrical workpieces such as pipe are described. The systems include a clamping assembly and can be used in various methods. In one method, the clamping assembly and a cutting tool or saw is used on a rotating workpiece. In another method, the clamping assembly and a cutting tool or saw is used on a stationary workpiece. Also described are frames that can be secured to the clamping assembly.
Claims21
A clamping system comprising:
- a base defining a threaded member;
- a pair of arms pivotally supported by the base, each arm defining a proximal end and an opposite distal end;
- a shaft threadedly engaged with the threaded member of the base, the shaft defining a proximal end and an opposite distal end;
- a central carriage rotatably affixed to the distal end of the shaft and slideably retained to the pair of arms;
- wherein rotation of the shaft relative to the base results in (i) axial displacement of the shaft and linear displacement of the central carriage, and (ii) pivotal displacement of the pair of arms.

A clamping system comprising:
- a base defining a threaded member;
- a pair of arms pivotally supported by the base, each arm defining a proximal end and an opposite distal end;
- a shaft threadedly engaged with the threaded member of the base, the shaft defining a proximal end and an opposite distal end;
- a central carriage rotatably affixed to the distal end of the shaft and slideably retained to the pair of arms;
- wherein rotation of the shaft relative to the base results in (i) axial displacement of the shaft and linear displacement of the central carriage, and (ii) pivotal displacement of the pair of arms,
- wherein each arm also defines a guide slot extending at least partially between the proximal end and the distal end of the arm, the clamping system further comprising:
- a first locating pin extending from the central carriage through the guide slot of a first arm of the pair of arms and a second locating pin extending from the central carriage through the guide slot of a second arm of the pair of arms to thereby movably retain the central carriage to the pair of arms;
- wherein each arm of the pair of arms includes one or more rollers,
- wherein the central carriage includes one or more rollers rotatably secured to the central carriage,
- wherein each arm of the pair of arms includes one or more rollers,
- wherein the central carriage includes one or more rollers rotatably secured to the central carriage.
8 more elements
A method of engaging a tool to a cylindrical workpiece, the method comprising:
- providing a clamping system including (i) a base defining a threaded member, (ii) a pair of arms pivotally supported by the base, each arm defining a proximal end and an opposite distal end, wherein the pair of arms include one or more rollers, each roller rotatably secured at the distal end of an arm of the pair of arms, (iii) a shaft threadedly engaged with the threaded member of the base, the shaft defining a proximal end and an opposite distal end, (iv) a central carriage rotatably affixed to the distal end of the shaft and slideably retained to the pair of arms, wherein the central carriage includes one or more rollers rotatably secured to the central carriage, wherein rotation of the shaft relative to the base results in axial displacement of the shaft and linear displacement of the central carriage, and pivotal displacement of the pair of arms;
- positioning the clamping system onto the cylindrical workpiece;
- rotating the shaft relative to the base until (i) the one or more rollers of the pair of arms, and (ii) the one or more rollers secured to the central carriage, contacts the cylindrical workpiece;
- securing the tool to the workpiece.
