Estimating the term…
The arrangement comprises a body constructed in the form of a grip clamp arable from the vertical axis of a workpiece, and having two jaws coupled with each other in the upper portion thereof by a clamping cylinder. The arrangement further comprises cutters for deburring, and a mechanism for pressing said cutters to the workpiece surface. The cutters are mounted in the lower portion of the jaws so that cutting edges thereof form a profile of the workpiece cross-section. The cuttes disposed on the same jaw are pivotally connected with each other. The mechanism for pressing the cutters is constructed in the form of a system of hydraulic cylinders mounted on the jaws in symmetrical relationship relative to the vertical axis of the body. Said hydraulic cylinders are provided with rods operatively connected to corresponding cutters.
Apparatus for removing burrs in butt welding of elongated workpieces, comprising a body constructed in the form of a clamp having mating workpiece-engaging jaws, said jaws each having first and second ends, a clamping cylinder coupled to said jaws proximate said first ends, a pair of elongated deburring cutters on each of said jaws proximate said second ends, a common pivot point on each of said jaws, means for mounting an end portion of each cutter of one of said pairs on said common pivot point, and piston and cylinder drive means for pressing said cutters to the workpiece surface in conformity with the shape thereof, said drive means including at least one hydraulic cylinder symmetrically mounted on each of said jaws and having piston rods operatively connected to the respective cutters of each pair to effect pivoting of said cutters about their respective common pivot point.
