Abstract
The utility model provides a kind of mechanical paw, comprise there is operating surface pedestal, be assembled in described pedestal and protrude out the telescopic shaft of described operating surface and be arranged at the pawl head of described telescopic shaft end, it is characterized in that: described pedestal with between telescopic shaft for ball-joint is connected, described mechanical paw is also provided with the elastic component of holding claws head pressure.Described ball-joint connects can make pawl head adaptation inclined surface produce suitable rotation, simultaneously by telescopic shaft and elastic component, ensure that fixing pressure, avoids dropping.
Description
Technical field
The utility model relates to manipulator field, particularly a kind of mechanical paw for pressure holding surface imperfection object.
Background technology
The application of manipulator very general, than if carry out the manipulator capturing and carry article.At present, when most manipulator captures object, often by some flat surfaces of article itself, apply certain pressure and ensure clamping, and then realize mobile.But, when carrying some and there is the object of indefinite inclined surface, capture process then more difficult, the phenomenon of landing easily occurs, needs a dead lift, affect workman and device security.
Given this, be necessary that a kind of mechanical paw newly of design solves the problems referred to above.
Utility model content
The technical problems to be solved in the utility model is: the mechanical paw providing the different inclined surface of a kind of flexible adaptation.
For achieving the above object, the utility model provides following technical scheme: a kind of mechanical paw, comprise there is operating surface pedestal, be assembled in described pedestal and protrude out the telescopic shaft of described operating surface and be arranged at the pawl head of described telescopic shaft end, described pedestal with between telescopic shaft for ball-joint is connected, described mechanical paw is also provided with the elastic component of holding claws head pressure.
Further, described elastic component is be sheathed on the spring outside described telescopic shaft.
Further, described both ends of the spring is respectively equipped with axially outward extending base end and pawl head end, and described base end is fixed on pedestal, and described pawl head end is fixed on pawl head.
Further, the pressing cross section of described pawl head is polygon.
Further, the pressing cross section of described pawl head is equilateral triangle, and the projection of described spring on pawl head drops in the circumcircle in described pressing cross section.
Further, described elastic component is be sheathed on the spring in described telescopic shaft.
Further, described ball-joint connects to comprise is located at the pedestal articular cavity of described operating surface side and the joint ball be located on telescopic shaft dorsad, and described operating surface is provided with the perforation communicated with described articular cavity.
Further, described telescopic shaft normality is perpendicular to described operating surface, and the swing cone angle that described ball-joint limits described telescopic shaft is 20 degree.
Further, the press surface of described pawl head is groove dentation, and the material hardness of pawl head is at least greater than by the twice of grabbing object materials hardness.
Compared with prior art, the utility model at least has the following advantages: described ball-joint connects can make pawl head adaptation inclined surface produce suitable rotation, simultaneously by telescopic shaft and elastic component, ensure that fixing pressure, avoids dropping.
Accompanying drawing explanation
Fig. 1 is the main TV structure schematic diagram of the utility model machinery paw.
Fig. 2 be the utility model machinery paw look up structural representation.
Detailed description of the invention
Refer to Fig. 1 and Fig. 2, describe structure and the utility model content of the utility model machinery paw below in conjunction with accompanying drawing.
The utility model machinery paw, comprise there is operating surface 101 pedestal 10, be assembled in described pedestal 10 and protrude out the telescopic shaft 20 of described operating surface 101 and be arranged at the pawl head 30 of described telescopic shaft 20 end, described pedestal 10 is connected for ball-joint 40 with between telescopic shaft 20, and described mechanical paw is also provided with the elastic component 50 of holding claws head 30 pressure.Described ball-joint 40 connects the inclined surface that pawl head 30 can be made to adapt to object and produces suitable rotation, simultaneously by telescopic shaft 20 and elastic component 50, ensure that fixing pressure, avoids dropping.
Described elastic component is be sheathed on the spring outside described telescopic shaft 20, and described both ends of the spring is respectively equipped with axially outward extending base end 501 and pawl head end 502, and described base end 501 is fixed on pedestal 10, and described pawl head end 502 is fixed on pawl head 30.The press surface 301 of described pawl head is polygon, the press surface 301 of the head of pawl described in the present embodiment 30 is equilateral triangle, the projection of described spring on pawl head 30 drops in the circumcircle of described press surface, one carrys out equilateral triangle can ensure to rotate more freely, and come circumcircle design also can ensure that spring is effectively supported.
Described ball-joint 40 connects to comprise is located at the pedestal articular cavity 401 of described operating surface side and the joint ball 402 be located on telescopic shaft 20 dorsad, described operating surface 101 is provided with the perforation 102 communicated with described articular cavity 401, described telescopic shaft 20 normality is perpendicular to described operating surface 101, the swing cone angle that described ball-joint 40 limits described telescopic shaft 20 is 20 degree, causes the reduction of positive pressure during to avoid amplitude of fluctuation excessive.The press surface 301 of described pawl head 30 is groove dentation, and the material hardness of pawl head is at least greater than by the twice of grabbing object materials hardness.
In sum, these are only preferred embodiment of the present utility model, scope of the present utility model should do not limited with this.Such as: in the present embodiment, described spring housing is located at outside described telescopic shaft, and in some other embodiment, described elastic component also can be sheathed in described telescopic shaft, as a part for telescopic shaft self, and the just large minor change relative difficulty of elastic force.Namely every simple equivalence change done according to the utility model claims and description with modify, all should still belong in scope that the utility model patent contains.
