Description
Technical field
The utility model relates to mechanical-electrical-hydraulic integration field, is specifically related to clamp device.
Background technique
The clamp device used in industrial production generally all adopts hydraulic transmission or pneumatic gearing.Adopt hydraulic transmission mode to need oil hydraulic pump to provide the hydraulic oil of pressure, adopt pneumatic gearing mode to need air pump to provide pressurized air.But, can have when carrying out transformation of energy with pump that energy loss is large, noise is large, manufacturing cost and use cost is high, use occasion is by the deficiency such as impact of pumping plant position.In addition, adopt hydraulic transmission inevitably can produce leakage and the volatilization of fluid, very large pollution is caused to environment; The leakage of fluid and the compressibility of liquid can affect the accuracy of actuator movement; Produce larger energy loss in hydraulic transmission, transmission efficiency can be caused lower; Do not have the Hydraulic Power Transmission System of accumulator pressurize, in the cutting process after clamping, oil hydraulic pump still needs running, and to keep the clamping force to clamped workpiece, this makes energy loss high.Pneumatic Transmission also has a comparatively fatal shortcoming, i.e. the as easy as rolling off a log leakage of pressurized gas, thus causes its working pressure lower.In the occasion requiring clamping force larger, often cause the volume of fixture too huge, to such an extent as to engineering structure cannot be born.
Summary of the invention
In order to solve the problem, the utility model provides a kind of structure simple, and step up reliable, energy consumption is low, and ouput force is easy to detect, and feeds back clamp device timely.
The utility model clamp device, comprise interconnective two oil hydraulic cylinders, be respectively input hydraulic cylinder and output hydraulic pressure cylinder, described oil hydraulic cylinder includes a rod chamber and a rodless cavity, is provided with hydraulic oil in described rodless cavity, and the rodless cavity of two-piston is connected by connecting tube, one of them piston rod is connected with a fastening device, be provided with spring in the rod chamber of another piston, one end of described spring is connected with piston rod, and the other end is connected with rod chamber.
Preferably, fastening device comprises the sliding screw and nut that cooperatively interact, described nut is provided with two chutes be parallel to each other, is provided with a slide block in chute, one end of described slide block is connected with fixed-hinged support by toggle, and the other end is connected with described piston rod by toggle.
Preferably, sliding screw is connected with an actuating motor by coupling.
Preferably, connecting tube is provided with a pressure relay, described pressure relay is connected with actuating motor.
The utility model utilizes two connected pistons and fastening device to realize the clamping of workpiece, for closing Hydrostatic Transfer Device, reliable clamping between piston.

Accompanying drawing illustrates: 1-actuating motor, 2-nut, 3-sliding screw, 4-input hydraulic cylinder, 5-pressure relay, 6-piston rod, 7-workpiece, 8-slide block, 9-toggle, 10-coupling, 11-output hydraulic pressure cylinder.
Embodiment
The utility model clamp device, comprise interconnective two oil hydraulic cylinders, be respectively input hydraulic cylinder 4 and output hydraulic pressure cylinder 11, described oil hydraulic cylinder includes a rod chamber and a rodless cavity, a piston rod 6 is provided with in described rod chamber, hydraulic oil is provided with in described rodless cavity, the rodless cavity of two-piston is connected by connecting tube, one of them piston rod 6 is connected with a fastening device, spring is provided with in the rod chamber of another piston, one end of described spring is connected with piston rod 6, and the other end is connected with rod chamber.Fastening device comprises the sliding screw 3 and nut 2 that cooperatively interact, described nut 2 is provided with two chutes be parallel to each other, be provided with a slide block 8 in chute, one end of described slide block 8 is connected with fixed-hinged support by toggle 9, and the other end is connected with described piston rod 6 by toggle 9.Sliding screw 3 is connected with an actuating motor 1 by coupling 10.Connecting tube is provided with a pressure relay 5, described pressure relay 5 is connected with actuating motor 1.
During use, actuating motor 1 drives sliding screw 3 to rotate through coupling 10 after rotating, and the straight line through sliding screw 3 rotary motion being converted to nut 2 moves up and down.Process two symmetrical chutes in nut 2 both sides, slide block 8 is placed in this two grooves with suitable Spielpassung.When nut 2 moves downward, slide block 8 slides in hole, the other end due to toggle 9 is connected with fixed-hinged support, thus promotion slide block 8 slides to the right in hole, another toggle 9 is connected with piston rod 6, thus promotion piston moves right in input hydraulic cylinder 4, and then the piston rod 6 that the hydraulic oil in closed hydraulic pressure cavity is produced in pressure promotion output hydraulic pressure cylinder 11 moves downward, thus clamping work pieces.
