Abstract
The utility model relates to a hydraulic clamp device which is used for clamping and unloading the tensile sample of a hydraulic universal test machine. An oil cylinder 2 is provided with an oil inlet 1 and an oil outlet 3. The middle part of a support bearing plate 5 is hinged on a connector 9 through pins 8 and screws 7. One end of the support bearing plate is hinged on the upper end of a connecting rod 6. The lower end of the connecting rod is fixedly connected with the piston of the oil cylinder pistons 4 though screw threads. The hydraulic clamp device with the structure has good stress situation. The support bearing plate and the oil cylinder piston are not easy to bend and break.
Description
This hydraulically operated fixture is used for the clamping and the pine of universal hydraulic testing machine tensile sample and unloads.
The hydraulically operated fixture of universal hydraulic testing machine employing at present has oil-in 1 and oil-out 3 on the oil cylinder 2 shown in figure two, oil cylinder piston 4 is slidingly connected with oil cylinder, and the oil cylinder piston upper end is fixedly connected with screw thread with supporting splint 5 one ends.By the oil inlet and oil return of oil cylinder oil-in and oil-out, oil cylinder piston is moved up and down, drive supporting splint parallel motion up and down.The other end of supporting splint inserts testing machine jaw clamp bottom, thereby the jaw clamp is moved up and down, and realizes that the clamping or the pine of testing machine jaw unloaded action.There is following defective in this anchor clamps: (1) supporting splint is a cantilever design, and when doing parallel motion up and down, stress is bad, buckling phenomenon often occurs; (2) moment of flexure that produced on oil cylinder piston of the impact force action of sample fracture moment is big, easily makes the crooked or fracture of oil cylinder piston.
The purpose of this utility model is to overcome the shortcoming that above-mentioned anchor clamps exist, and a kind of hydraulically operated fixture of new construction is provided.
The purpose of this utility model is achieved in that shown in figure one, adopts the connecting rod link structure.Have oil-in 1 and oil-out 3 on the oil cylinder 2; The middle part of supporting splint 5 and connector 9 are hinged, and the upper end of supporting splint one end and connecting rod 6 is hinged, and the lower end and the oil cylinder of connecting rod are hinged, and connector lower end and oil cylinder piston 4 are fixedly connected.By the oil-in of oil cylinder and the oil inlet and oil return of oil-out, oil cylinder piston is moved up and down, drive supporting splint and swing up and down.The other end of supporting splint inserts testing machine jaw clamp bottom, thereby the jaw clamp is moved up and down, and realizes that the clamping or the pine of testing machine jaw unloaded action.Connecting rod props up spot wobble along with swinging up and down of supporting splint around oil cylinder, and supporting splint and the suffered impulsive force of oil cylinder piston are played the buffer shock-absorbing effect.
The utility model has the advantages that: owing to replaced original cantilever design with the connecting rod link structure, thus supporting splint and oil cylinder piston force-bearing situation are greatly taken on a new look.(1) supporting splint swings up and down steadily, and is not flexible after stressed; (2) moment of flexure that produced on oil cylinder piston of the impact force action of sample fracture moment reduces greatly, thereby oil cylinder piston is not flexible or fracture.
