Abstract
The utility model discloses a hydraulic clipping device which comprises a hydraulic cylinder and two flexible clipping components: a first clipping component and a second clipping component. The hydraulic cylinder comprises a cylinder and a piston rod. The first clipping component is connected with the cylinder and the second clipping component is connected with the piston rod. When the hydraulic cylinder is pumped with pressure oil a relative motion will be produced between the piston rod and the cylinder, which can produce a relative motion between the first clipping component and the second clipping component which are respectively connected with the cylinder and the piston rod to clip the awaiting clipped objects tightly. Compared with the hydraulic clipping device of the prior art the utility model has a more simple structure and a convenient maintenance. For driving two flexible clipping devices the technique scheme of the utility model can save a hydraulic cylinder and therefore the cost can be reduced.
Description
Technical field
The utility model relates to a kind of clamping device, particularly relates to a kind of clamping device that clamping force is provided with hydraulic pressure.
Background technology
Clamping device be widely used in the various plant equipment and various mechanical technology processes in, for example the clamping mechanism in employed anchor clamps and the injection machine all is common clamping device in the mechanical processing process.The clamping force of clamping device generally derives from the fastening force of screw thread or the pressure of hydraulic means etc., owing to hydraulic clamp can be controlled automatically and is common in some plant equipment.Clamping device generally comprises two clamping elements, object to be pressed from both sides places between two clamping elements and is clamped, in hydraulic clamp commonly used, it is movable having only a clamping element, another clamping element is fixed, the clamping element of hydraulic cylinder promotion activity moves with respect to fixing clamping element, thereby the object of centre is clamped; And in some application scenarios are arranged, it all be movable needing two clamping elements, and they are jointly to intermediary movements, thereby the object of centre is clamped, such clamping device promotes two clamping elements respectively by two hydraulic cylinders at present, exists defectives such as complex structure, manufacturing cost height.
The utility model content
The technical problems to be solved in the utility model provides the simpler hydraulic clamp of a kind of structure.
In order to solve the problems of the technologies described above, the utility model adopts following technical scheme: a kind of hydraulic clamp, comprise hydraulic cylinder and two mobilizable first clamping elements and second clamping element, described hydraulic cylinder comprises cylinder barrel and piston rod, described first clamping element is connected with cylinder barrel, and second clamping element is connected with piston rod.
The utility model only just can drive the clamping element generation clamping force of two activities with a hydraulic cylinder, after feeding pressure oil in the hydraulic cylinder, produce relative motion between piston rod and the cylinder barrel, thereby make first clamping element and second clamping element that are connected with them respectively produce relative motion, will wait to press from both sides object and clamp.Compare with hydraulic clamp of the prior art, the utility model structure is simpler, and is easy to maintenance.For drive two can be movable clamping element, the technical solution of the utility model can be saved a hydraulic cylinder, therefore can reduce cost.
As improvement of the technical scheme, be provided with and wait to press from both sides the holes for clamping that the profile of object adapts between described first clamping element and second clamping element.Holes for clamping can increase the contact area between clamping element and the caught object, can cooperate closelyr.
As a kind of preferred version of technique scheme, fix a flange on the described cylinder barrel, also comprise the pull bar of two and symmetric arrangement parallel with piston rod, an end of described pull bar is fixed on the flange, and the other end is connected with first clamping element.Owing to be fixed with flange and two pull bars on the cylinder barrel, to be convenient to be connected with first clamping element, two pull bar symmetric arrangement can make the stressed balanced more of clamping element.
As the improvement of above-mentioned preferred version, described second clamping element is provided with two through holes, and these two through holes that described two pull bars pass on second clamping element are connected with first clamping element.Through hole on second clamping element can be so that being connected of two pull bars and first clamping element, and through hole can also play the guide effect to pull bar simultaneously.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Fig. 1 is the structural representation of the utility model hydraulic clamp.
The specific embodiment
As shown in the figure, hydraulic clamp of the present utility model comprises the holes for clamping 7 that the profile that is provided with and waits to press from both sides object between two mobilizable first clamping elements 1 and second clamping element, 2, the first clamping elements 1 and second clamping element 2 adapts.The piston rod 5 of hydraulic cylinder is fixedly connected on second clamping element 2 by screw thread, fix a flange 6 on the cylinder barrel 6 of hydraulic cylinder, two and pull bar 3 one ends symmetric arrangement parallel with piston rod 5 are fixed on the flange 4, and the other end is connected by screw thread with first clamping element 1.Second clamping element 2 is provided with two through holes, and these two through holes that two pull bars 3 pass on second clamping element 2 are connected with first clamping element 1.
Under the free state, behind the logical oil of hydraulic jack, then can produce relative motion between hydraulic cylinder cylinder barrel 6 and the piston rod 5, if the resistance that hydraulic cylinder cylinder barrel 6 is subjected to is little, then cylinder barrel 6 motion earlier; If the resistance that piston rod 5 is subjected to is little, then piston rod 5 motion earlier.After Yun Dong a side ran into bigger extraneous resistance in the ban, the opposing party is relative motion round about.Promptly under free state, to the logical oil of hydraulic cylinder, piston rod 5 and cylinder barrel 6 relative motions reach the effect that piston rod 5 stretches out, and two clamping elements 1,2 are clamped; Behind the oppositely logical oil, piston rod 5 and cylinder barrel 6 do relative motion once more, reach the purpose of piston rod 5 withdrawals, and two clamping elements 1,2 are unclamped.The utility model only just can drive the clamping element generation clamping force of two activities with a hydraulic cylinder, compare with hydraulic clamp of the prior art, and the utility model structure is simpler, also more saves cost.
