Abstract
The utility model provides a hand claw device of hydraulic pressure machinery hand, technical scheme be as follows: including ECU, motor, piston rod, spring, pneumatic cylinder, hydraulic pressure connecting rod, mechanical finger etc.. ECU can the control motor the operating switch state, the motor during operation can drive the compression of piston rod. The hydraulic oil in the pneumatic cylinder can be compressed in the piston rod motion, drives the motion of hydraulic pressure connecting rod to it presss from both sides tight operating mode to make the mechanical finger do. The beneficial effect of the utility model as follows: when pressing from both sides tight operating mode, the motion of motor drive piston rod, the interior hydraulic oil of compression pneumatic cylinder drives the mechanical finger through the hydraulic pressure connecting rod and does the tight operating mode of clamp, and when opening the operating mode, the motor does not need work, under the spring action of spring, drives piston rod and hydraulic pressure connecting rod and is recurrent motion to reach the state of opening, the working process under two kinds of operating modes is all comparatively simple, and overall structure simply is convenient for make.
Description
Technical field
The utility model relates to a kind of hydraulic machinery field, particularly relates to a kind of paw device of hydraulic efficiency manipulator.
Background technology
At present along with the development of mechanization and automation, in every profession and trade, the pickup work of object or workpiece has all been come by manipulator.The design more complicated all comparatively speaking of major part manipulator, manufacture cumbersome, cost is relatively high, therefore designs a kind of structure simple, the paw device of hydraulic efficiency manipulator easy to manufacture.
Summary of the invention
The utility model provides a kind of paw device of hydraulic efficiency manipulator, and in the pickup course of work, opening and clamping operating mode of manipulator is all to provide power by hydraulic pressure.
A paw device for hydraulic efficiency manipulator, comprises ECU, motor, piston rod, spring one, spring two, spring three, hydraulic cylinder, left hydraulic connecting rod, right hydraulic connecting rod, left mechanical finger, right mechanical finger.Wherein said ECU is connected with motor; Described motor is connected with piston rod; Described piston rod is connected with hydraulic cylinder with spring two by spring one; Described left mechanical finger is connected with hydraulic cylinder by left hydraulic connecting rod and spring three; Described right mechanical finger is connected with hydraulic cylinder by right hydraulic connecting rod and spring three.
The utility model tool has the following advantages:
1) structure is simple, is convenient to manufacture;
2) hydraulic pressure provides power, dynamical stability during work;
3) flexible movements, go for various working.
Accompanying drawing explanation
Fig. 1 is the structure chart of the paw device of hydraulic efficiency manipulator;
1, ECU, 2, motor, 3, piston rod, 4, spring one, 5, spring two, 6, hydraulic cylinder, 7, spring three, 8, left hydraulic connecting rod, 9, right hydraulic connecting rod, 10, left mechanical finger, 11, right mechanical finger.
Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is further described.
As shown in Figure 1, a kind of paw device of hydraulic efficiency manipulator, ECU1 is connected with motor 2, and the operating switch state of motor 2 is controlled by ECU1.Motor 2 is connected with piston rod 3, piston rod 3 can be driven to carry out compression movement, promote the motion of hydraulic oil when motor 2 works.Piston rod 3 is connected with hydraulic cylinder 6 with spring 25 by spring 1, the state before spring 1 and spring 25 can utilize the elastic force of self to make piston rod 3 automatically return to compression after compression process terminates.Left hydraulic connecting rod 8 is connected with hydraulic cylinder 6 by spring 37 with right hydraulic connecting rod 9, and left mechanical finger 10 is connected with left hydraulic stem 8, and right mechanical finger 11 is connected with right hydraulic stem 9.When piston rod 3 does compression movement under the drive of motor 2, promotion hydraulic oil moves, spring 1 and spring 25 become compressive state, hydraulic oil promotes left hydraulic connecting rod 8 and right hydraulic connecting rod 9 respectively to outer motion, spring 37 becomes stretched condition, left hydraulic connecting rod 8 and right hydraulic connecting rod 9 outwards move, and drive left mechanical finger 10 and right mechanical finger 11 to do clamping operating mode.After piston rod 3 terminates compression condition, spring 1 and spring 25 restPose, promote piston rod 3 to move upward, the spring 37 being simultaneously in tensioning state also restPoses, drive left hydraulic connecting rod 8 and right hydraulic connecting rod 9 inwardly to move, thus drive left mechanical finger 10 and right mechanical finger 11 to do to open operating mode.
