Abstract
A compression tool for joining tubular workpieces is provided with two or more arcuate compression jaws displaceable relative to each other in such a manner that the jaws can be opened for placement o a tubular segment of the workpiece. The compression tool (121) comprises compression jaw supports (132, 133) pivotally mounted on pivot bolts (134, 135). Two compression jaws (142-145) of each jaw support are guided along guide surfaces (138-141) which subtend an angle symmetrical to the center of the compression space when the compression jaws are in a closed state. The compression jaws are biased by a spring (146-149) along the guide surfaces (138-141) toward terminal end stops (150-153). Movement of the jaw supports about the pivot bolts (126, 127) permits opening and closing of the compression jaws.
Claims20
A compression tool, comprising:
- a) first and second adjacently disposed pivot levers;
- b) first and second jaw supports, each support pivotally connected to one of said levers and pivotal relative thereto for being displaced relative to the other pivot lever and to an axis centrally disposed relative to said supports and said axis extending generally perpendicular to the direction of movement of said supports;
- c) a plurality of moveable compression jaws, at least two moveable jaws operably associated with each support and the jaws of one support being uniformly spaced relative to the jaws of the other support;
- d) first and second guide means operably associated with each of said supports, one of said guide means of each support oriented in a first direction and the other of said guide means of each support oriented in an opposite direction so that the guide means of each support subtend an angle symmetrical with said axis and opening thereto;
- e) each of said jaws operably associated with one of said guide means and moveable relative thereto as said supports are displaced by said pivot levers;
- f) each of said guide mans is bounded by a first and a second terminal end portion of the associated jaw support, and each of said terminating second end portions extends outwardly from the associated guide means for thereby providing a stop for the associated jaw.
A compression tool, comprising:
- a) first and second adjacently disposed jaw supports, each support having upper and lower guide surfaces and the upper guide surface of each support opening toward the lower guide surface of the opposite support;
- b) pivot lever means operably associated with said supports for moving said supports relative to each other and to an axis disposed centrally between said supports and extending transverse to the direction of movement of said supports;
- c) each guide surface disposed at an angle to said axis, one guide surface of each support oriented in a first direction and the other guide surface thereof oriented in an opposite direction so that all guide surfaces are directed toward said axis;
- d) a plurality of moveable compression jaws, each moveable jaw operably associated with one of said supports and having a jaw surface moveable along an associated guide surface and each said jaw surface being bounded by the associated support so that each jaw moves radially relative to said axis and to the associated guide surface as the associated support is moved;
- e) each guide means is straight and is bounded at one terminal end by a stop and at an opposite end by a biasing means urging the associated jaw toward the stop.
