Abstract
A clamping device including a clamp housing a generally horizontally extending cylinder bore that opens into an upwardly and rearwardly sloping guide bore formed in a front portion of the clamp housing is disclosed. A clamping member is shiftably mounted within the guide bore and a piston is shiftably mounted within the cylinder bore. The clamping member is formed with a groove into which a projection, carried by the piston, is fitted. By this arrangement, movement of the piston forces the clamping member to shift in an inclined direction between clamping and unclamping positions.
Claims5
A hydraulic clamp comprising:
- a clamp housing (2) having a front portion and a rear portion;
- a guide bore (16) formed in the front portion of said clamp housing (2), said guide bore sloping rearwardly and upwardly from the front portion of said clamp housing;
- a clamping member (5) having a driven portion (34) and being shiftably mounted within said guide bore (16);
- a hydraulic cylinder (17) having a cylinder bore (18) formed generally horizontally in the rear portion of said clamp housing (2) and opening into said guide bore (16);
- a piston (19) shiftably mounted within said cylinder bore (18);
- and
- a push/pull drive portion (30) disposed before said piston (19) so as to be connected to said piston (19);
- said driven portion (34) of said clamping member (5) being interconnected with said push/pull drive portion (30) with a vertical gap therebetween such that when said push/pull drive portion is shifted with said piston within said cylinder bore, said push/pull drive portion (30) will force said clamping member (5) to shift in an inclined direction within said guide bore by the interconnection of said driven portion (34) with said push/pull drive portion (30).
