Detailed description of the invention
Below in conjunction with drawings and Examples, to above-mentioned being described in more detail with other technical characteristic and advantage of the present invention.
As shown in Figure 1, the hydraulic clamping device of a kind of swingable jaw of the present invention, comprises device outrigger 7, and device outrigger 7 left end is hollow structure, be provided with hydraulic cylinder 8 in this hollow structure, on the left of device outrigger 7, be provided with the first clamping jaw 1 and the second clamping jaw 11 of two upper and lower settings, be connected with on two between clamping jaw 1 right-hand member and hollow structure left frame, the first connecting rod 3 of lower setting and second connecting rod 5, first connecting rod 3 one end is by the first tie point 2 rotating connection clamping jaw 1, the other end is by the left frame of the rotating connection hollow structure of the second tie point 4, second connecting rod 5 one end is rotatably connected by the 3rd tie point 9 and clamps jaw 1, the other end is by the left frame of the rotating connection hollow structure of the 4th tie point 10, second connecting rod 5 other end to be extended in described hollow structure and the tail end of the hydraulic cylinder 8 that is rotatably connected by the 5th tie point 6, be connected with on two between clamping jaw 11 right-hand member and hollow structure left frame, the double leval jib 13 of lower setting and third connecting rod 12, double leval jib 13 to extend in described hollow structure and the front end of hydraulic cylinder piston rod 15 by the rotating connecting fluid cylinder pressure 8 of the 6th tie point 14, clamping jaw 1, first connecting rod 3 and second connecting rod 5 and clamping jaw 11, third connecting rod 12 and double leval jib 13 are identical symmetrical structure, formed with each tie point as the rotating four-bar linkage structure in axle center.
Wherein the left frame of hollow structure is hatch frame, and the Opening length of this hatch frame is less than the length of left frame; The distance of the first tie point 2 to the three tie point 9 equals the distance of the second tie point 4 to the four tie point 10, and the distance of the first tie point 2 to the second tie point 4 equals the distance of the 3rd tie point 9 to the four tie point 10, make first connecting rod 3 parallel with second connecting rod 5, due to symmetrically, in like manner third connecting rod 12 is parallel with double leval jib 13.
At the first linking point 2 place, first connecting rod 3 can rotate relative to clamping jaw 1; At the 3rd linking point 9 place, second connecting rod 5 can rotate relative to clamping jaw 1.At the second linking point 4 place, first connecting rod 3 can rotate relative to device outrigger 7; At the 4th linking point 10 place, second connecting rod 5 can rotate relative to device outrigger 7.In like manner due to symmetrical structure each other, third connecting rod 12 and double leval jib 13 also can rotate at respective tie point place.
In the hollow structure that second connecting rod 5 extends to device outrigger 7, one end is connected with the cylinder body tail end of hydraulic cylinder 8 by the 5th linking point 6, and at the 5th linking point 6 place, second connecting rod 5 can rotate relative to hydraulic cylinder 8.The connection of clamping jaw 11 and device outrigger 7 is symmetrical with the connection of clamping jaw 1 and device outrigger 7, in the hollow structure that double leval jib 13 extends to device outrigger 7, one end is connected by the front end of the 6th linking point 14 with the hydraulic cylinder piston rod 15 of hydraulic cylinder 8, at the 6th linking point 14 place, double leval jib 13 can rotate relative to hydraulic cylinder piston rod 15.
Because the first linking point 2 is to equal in the distance of Distance geometry second linking point 4 to the four linking point 10 of the 3rd linking point 9, and the distance of the first linking point 2 to the second linking point 4 and the 3rd linking point 9 to the four linking point 10 is equal, so above structure composition parallelogram four-bar linkage, be close together so clamping jaw 1 and clamping jaw 11 can be made when the hydraulic cylinder piston rod 15 of hydraulic cylinder 8 stretches out to move in parallel, thus play the effect of clamping.
Because several connecting rod can freely rotate at tie point, so clamping jaw 1 and clamping jaw 11 can swing certain angle relative to device outrigger 7.
Above-described embodiment is only be described the preferred embodiment of the present invention; not scope of the present invention is limited; under not departing from the present invention and designing the prerequisite of spirit; the various distortion that those of ordinary skill in the art make technical scheme of the present invention and improvement, all should fall in protection domain that claims of the present invention determines.
