Setting, can be enhanced the frictional force between clamping part 144 and workpiece, stablize so as to improve claw 140 to the clamping of workpiece
Property.
In one embodiment, clamping part 144 is provided with chamfering 148 far from one end of assisted parts 142.Pass through chamfering 148
Setting, can play a certain protective role workpiece, claw 140 is avoided to cause to scrape to workpiece during grabbing workpiece
Wound, guarantees the quality of workpiece.
As shown in Fig. 2, further, in one embodiment, the inside of pedestal 110 offers compensated cavity (figure is not marked).Bottom
One end of seat 110 is also provided with the through-hole 111 being connected with compensated cavity.Actuator 120 is placed in compensated cavity.Shaft 122 is by leading to
Hole 111 exposes to pedestal 110.Installation fixed form by using actuator 120 with respect to the compensated cavity inside pedestal 110, can
To carry out effective protection to actuator 120, in order to normal use of the jaw means 100 under the environmental condition of rather harsh.
It should be pointed out that in one embodiment, actuator 120 can be driving cylinder.Further, actuator 120
With inner cavity (figure is not marked).The one end of shaft 122 far from chuck 130 is rotatably set to interior intracavitary.Actuator 120 is also connected with
It is provided with trachea 124.Trachea 124 is connected with inner cavity.Trachea 124 is used to inflate to inner cavity with 122 phase of drive shaft
Rotation to pedestal 110.In one embodiment, the side of pedestal 110 is also provided with the through slot 112 being connected with compensated cavity.It connects
Tracheae 124 exposes to pedestal 110 by through slot 112.
As shown in Fig. 2, further, in one embodiment, pedestal 110 includes the first connector 113 being connected and the
Two connectors 114.First connector 113 and the second connector 114 are enclosed compensated cavity.First connector 113 is cube
Structure.The assisted parts 142 of claw 140 is rotatablely arranged at the one end of the first connector 113 far from the second connector 114.It is logical
