Abstract
The utility model relates to a hydraulic clamping mechanism. The hydraulic clamping mechanism is provided with a hanging bracket and clamping mechanisms arranged below the hanging bracket. The number of the clamping mechanisms is two, and each set of clamping mechanisms is provided with hydraulic cylinders, piston rods, bending rods and clamp holders. The upper ends of the hydraulic cylinders are symmetrically connected on the hanging bracket through hinges. Two ends of the bending rods are respectively connected with the lower ends of the piston rods and the upper ends of the clamp holders in a rotating mode through the hinges. Bending positions of the bending rods are connected with the hanging bracket in a rotating mode through the hinges. The hydraulic clamping mechanism has the advantages that the two piston rods can be pushed to move vertically through a hydraulic control system of a mechanism arm; due to the fact that the bending rods can only rotate around the hinges on the bending positions, the two hydraulic cylinders (with the piston rods) simultaneously swing around the hinges above the hydraulic cylinders; a parallelogram mechanism is skillfully adopted, when the two piston rods move downwards, the two clamp holders are driven to conduct parallel translation towards the outer side, namely the two clamp holders open and insert to work pieces; and when the two piston rods move upwards, the two clamp holders are folded to clamp the work pieces.
Description
Technical field
The utility model relates to a kind of clamping device, particularly a kind of hydraulic pressure clamping device.
Background technology
In the automation assembling process, often to grasp, assemble part.If adopt the Purely mechanical structure to realize the portable part that grasps, the stationarity of often structure more complicated, and extracting part is usually unsatisfactory.
The utility model content
The purpose of this utility model is to overcome the defective that prior art exists, and a kind of simple in structure, easy to operate hydraulic pressure clamping device is provided.
Realize that the utility model purpose technical scheme is: a kind of hydraulic pressure clamping device has suspension bracket and the clamping device that is arranged on the suspension bracket below; Described clamping device has two groups, and every group all has hydraulic cylinder, piston rod, pole and clamper; The upper end of described hydraulic cylinder is connected on the suspension bracket by the hinge symmetry; The two ends of described pole are connected to the lower end of piston rod and the upper end of clamper by hinge, and the bending part of pole is connected through the hinge on suspension bracket.
The described clamping device of technique scheme also has straight-bar; The two ends of described straight-bar are connected on suspension bracket and the clamper by hinge.
The described straight-bar of technique scheme is parallel with one side of pole.
The described two groups of poles of technique scheme all bend inwards.
The described suspension bracket of technique scheme is down " recessed " font.
The described suspension bracket of technique scheme upper end central authorities have a connecting plate; Described connecting plate is connected with mechanical arm.
After adopting technique scheme, the utlity model has following positive effect: the utility model can promote two piston rods and move up and down by the hydraulic control system of mechanical arm; Because pole can only be around the hinge through of its turning point, therefore two hydraulic cylinders (together with piston rod) are done swing simultaneously with the hinge above it; Owing to adopted parallel-crank mechanism dexterously, make that will drive two clampers when two piston rods move downward does parallel movement laterally, namely two binding clasps open, and stretch to workpiece; And when two piston rods moved upward, two clampers namely closed up, thus holding workpiece, and entire mechanism is simple in structure, easy to operate, and stationarity is good, is easy to realize.
Description of drawings
For the easier quilt of content of the present utility model is understood, according to specific embodiment also by reference to the accompanying drawings, the utility model is described in further detail, wherein below
Fig. 1 is structural representation of the present utility model;
1. suspension brackets among the figure, 2. clamping device, 21. hydraulic cylinders, 22. piston rods, 23. poles, 24. clampers, 25. straight-bars, 3. connecting plate.
The specific embodiment
(embodiment 1)
See Fig. 1, the utlity model has suspension bracket 1 and the clamping device 2 that is arranged on suspension bracket 1 below; Suspension bracket 1 is down " recessed " font; Suspension bracket 1 upper end central authorities have a connecting plate 3; Connecting plate 3 is connected with mechanical arm.Clamping device 2 has two groups, and every group all has hydraulic cylinder 21, piston rod 22, pole 23 and clamper 24; The upper end of hydraulic cylinder 21 is connected on the suspension bracket 1 by the hinge symmetry; Two groups of poles 23 all bend inwards, and the two ends of pole 23 are connected to the lower end of piston rod 22 and the upper end of clamper 24 by hinge, and the bending part of pole 23 is connected through the hinge on suspension bracket 1.
Clamping device 2 also has straight-bar 25; The two ends of straight-bar 25 are connected on suspension bracket 1 and the clamper 24 by hinge, and straight-bar 25 is parallel with one side of pole 23.
Operation principle of the present utility model is: during work, can promote two piston rods and move up and down by the hydraulic control system of mechanical arm; Because pole can only be around the hinge through of its turning point, therefore two hydraulic cylinder 21(are together with piston rod 22) hinge above it is done swing simultaneously; Owing to adopted parallel-crank mechanism dexterously, make that will drive two clampers 24 when two piston rods 22 move downward does parallel movement laterally, namely two clampers 24 open, and stretch to workpiece; And when two piston rods 22 moved upward, two clampers 24 namely closed up, thus holding workpiece.
Above-described specific embodiment; the purpose of this utility model, technical scheme and beneficial effect are further described; institute is understood that; the above only is specific embodiment of the utility model; be not limited to the utility model; all within spirit of the present utility model and principle, any modification of making, be equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.
