Technical field
The utility model relates to a kind of manipulator, particularly relate to a kind of have multiplely pick and place paw thus the manipulator of enhancing productivity, belong to automated machine technical field.
Background technology
Manipulator can imitate some action of staff and arm, is widely used in each processing industry, especially automated productin line, partly to replace manual operation, reduces labour intensity and Labor Risk.In the machining production processes such as welding, assembling, die casting, generally all need to carry out blowing and feeding operation to workpiece, workpiece to be processed is positioned over processing stations, after machining, then the workpiece processed is taken out, enter next manufacturing procedure.In prior art, blowing and feeding are often carried out respectively, and this extends process time to a certain extent, reduce production efficiency.
Summary of the invention
The utility model, for the above-mentioned technical problem existed in prior art, provides a kind of manipulator, realizes synchronously carrying out of blowing and feeding, thus enhances productivity.For this reason, the utility model adopts following technical scheme:
A kind of manipulator, comprise base and be arranged at the mechanical arm on base, it is characterized in that: on described mechanical arm, be provided with at least two mechanical paws, described mechanical arm is can respect thereto lifting and rotating under the effect of the first power set, mechanical paw can stretch relative to mechanical arm under the effect of the second power set, mechanical paw has and can be movable relatively thus open a pair dactylus with closed mechanical paw, and this can do relative motion to dactylus under the effect of the 3rd power set.By arranging at least two mechanical paws, and mechanical paw can be elevated, rotates under the effect of power set, opening and closing, in the streamline process of workpiece, can realize the good linking that workpiece takes, puts, saving process time, thus enhances productivity.
Further, described first power set comprise for driving device arm rotate rotating servo motor and for driving device arm lifting lift cylinder or lift servo motor.Realize rotation and the lifting of mechanical arm, thus driving mechanical paw rotates and upgrading.
Further, described rotating servo motor is arranged at the below of mechanical arm and is connected with base by a mount pad, supportingly between mount pad and base be provided with slide rail and slide block, lift cylinder or upgrading servomotor are arranged on base, and its clutch end is connected with mount pad.Realize the lifting of mechanical arm and mechanical paw.
Further, between described rotating servo motor and mechanical arm, an accurate harmonic wave speed reducing machine is also provided with.Control accurately, effective.
Further, described second power set are be arranged at telescopic cylinder on mechanical arm or flexible servomotor, and its clutch end is connected with mechanical paw, supportingly between mechanical arm and mechanical paw are provided with slide rail and slide block.Realize mechanical paw stretching relative to mechanical arm.
Further, described 3rd power set are opening and closing cylinder.Realize the opening and closing of mechanical paw.
Further, arrange between adjacent machine paw with certain at an angle, described angle is 30-180 degree.Make to be spaced a distance between adjacent machine hand non-parallelly, be convenient to the carrying out picking and placeing work piece operations.
Further, described mechanical paw is 2-6.Multiple mechanical paw can simultaneously operating, enhances productivity.
Further, described mechanical paw is 2, and the angle between two mechanical paws is 90 degree.Take into account the actuating length of mechanical paw and pick and place the action need of workpiece, enhancing productivity.
Further, described a pair dactylus is removably connected on mechanical paw by a mount pad.Difform dactylus can be selected to install according to need of production, meet causing the demand of different workpieces.
Therefore, manipulator of the present utility model, multiple mechanical paw coordinates the power set of each action, realizes synchronously carrying out of blowing and feeding, and action is coherent, compact, and production efficiency is high.

Detailed description of the invention
Be described further the utility model with detailed description of the invention below in conjunction with Fig. 1-5, part same as the prior art in the utility model is with reference to prior art.
As Figure 1-5, manipulator of the present utility model, the mechanical arm 2 comprising base 1 and be arranged on base 1, mechanical arm 2 is provided with two mechanical paws 3, at mechanical arm 2 can respect thereto lifting and rotating under the effect of the first power set, mechanical paw 3 can stretch relative to mechanical arm 2 under the effect of the second power set, mechanical paw 3 has and can be movable relatively thus open a pair dactylus 3a and 3b with closed mechanical paw, and this can do relative motion to dactylus under the effect of the 3rd power set.3rd power set are an opening and closing cylinder (not shown).
Wherein: the first power set comprise the rotating servo motor 4 rotated for driving device arm 2 and the lift cylinder 5 be elevated for driving device arm 2, an accurate harmonic wave speed reducing machine 6 is also provided with between rotating servo motor 4 and mechanical arm 2, rotating servo motor 4 is arranged at the below of mechanical arm 2 and is connected with base 1 by a mount pad 7, supportingly between mount pad 7 and base 1 be provided with slide rail 8 and slide block 9, the cylinder block of lift cylinder 5 is arranged on base 1, and its clutch end-cylinder rod is connected with mount pad 7.Second power set are the telescopic cylinder 10 be arranged on mechanical arm 2, and its clutch end-cylinder rod is connected with mechanical paw 3, supportingly between mechanical arm 2 and mechanical paw 3 are provided with slide rail 8 and slide block 9.
Mechanical paw 3 is 2-6, and between adjacent machine paw, angle is 30-180 degree, and in the present embodiment, the quantity of mechanical paw is 2, and the angle between two mechanical paws is 90 degree.
A pair dactylus 3a and 3b is removably connected on mechanical paw 3 by a mount pad.
The utility model is in the process used, when a mechanical paw is used for the workpiece processed to take away, the workpiece to be processed grasped can be positioned over processing stations by other mechanical paw, realizes taking, putting of workpiece and synchronously carries out, save process time, improve production efficiency.Meanwhile, coordinate and carry out the power set of each action, lifting, rotation can be completed, stretch, the action such as folding, the flow production line of all kinds of processing industry can be widely used in, to enhance productivity.
Certainly, the utility model also has other embodiments, is only preferred embodiment of the present utility model above, is not used for limiting practical range of the present utility model, all equivalences done according to the content of the application's the scope of the claims change and modify, and all should be technology category of the present utility model.
