The working principle of the invention is as follows:
in this embodiment, the finger module of the three-finger grip jaw mainly has three working positions: parallel pose, centering pose and two-finger grasping pose. Unlike the first finger module 3 in a fixed orientation, the second finger module 4 and the third finger module 5 are designed to rotate around their axes at the same angle and in opposite directions. The parallel pose is defined as the pose of the first finger module 3 when the second finger module 4 and the third finger module 5 are parallel to each other, and the second finger module 4 and the third finger module 5 are rotated by 0 ° as shown in fig. 5 and 6, which are schematic diagrams of parallel grasping of a rectangular parallelepiped and enveloping grasping of an object in the parallel pose of the three-finger gripper. When the second finger module 4 rotates clockwise by 60 degrees around the axis, the third finger module 5 rotates counterclockwise by 60 degrees, and at the moment, the three finger modules are symmetrically distributed on the clamping jaw housing 1 in pairs at an angle of 120 degrees, which is called a centering pose, as shown in fig. 7, the three finger clamping jaws envelop the gripping ball in the centering pose. When the second finger module 4 rotates clockwise by 90 ° around the axis, the third finger module 5 rotates counterclockwise by 90 °, and the second finger module 4 and the third finger module 5 are parallel and opposite to each other, which is called a two-finger gripping pose, as shown in fig. 8, which is a schematic diagram of parallel gripping of a small square block in a three-finger gripper centering pose.
The working principle of the driving module is as follows:
the first driving motor 12 rotates, and transmits torque through the first power transmission system 14, that is, the first transmission mechanism 22 and the second transmission mechanism 23 drive the first driving rod 16, the second driving rod 17 and the third driving rod 18 to synchronously and linearly move along the axis direction of the first driving rod, the second driving rod 17 and the third driving rod 18; the second driving motor 13 rotates, and transmits torque through the second power transmission system 15, that is, the second driving rod 17 and the third driving rod 18 are respectively driven to rotate around their axes by the first steering transmission mechanism 24 and the second steering transmission mechanism 25.
In this embodiment, when the first driving motor 12 rotates, the first grasping transmission gear 26 is driven to rotate, the second grasping transmission gear 27 engaged therewith rotates to drive the coaxial lead screw 28 to rotate, so that the nut slider 29 linearly moves along the axial direction of the lead screw 28, and the first driving rod 16, the second driving rod 17 and the third driving rod 18 mounted on the nut slider 29 synchronously and linearly move to drive the fingers of the first finger module 3, the second finger module 4 and the third finger module 5 to extend, thereby completing the grasping, operation and release of the self-adaptive grasping.
In this embodiment, when the second driving motor 13 rotates clockwise, the first steering transmission gear 30 and the third steering transmission gear 32 which are coaxial are driven to rotate clockwise, the first steering transmission gear 30 drives the engaged second steering transmission gear 31 to rotate counterclockwise, and the second driving rod 17 is driven to rotate counterclockwise around the axis of the second driving rod; the third steering transmission gear 32 rotates clockwise to drive the engaged fourth steering transmission gear 33 to rotate anticlockwise, so as to drive the fifth steering transmission gear 34 to rotate clockwise, so that the third driving rod 18 rotates clockwise around the axis thereof, and the anticlockwise rotation of the second finger module 4 and the clockwise rotation of the third finger module 5 are realized. When the second driving motor 13 rotates counterclockwise, the first steering transmission gear 30 and the third steering transmission gear 32 which are coaxial are driven to rotate counterclockwise, the subsequent process is just opposite to the process of grabbing the object, which is not repeated, and clockwise rotation of the second finger module 4 and counterclockwise rotation of the third finger module 5 are realized.
The invention has the advantages that:
1) the dual-drive motor is adopted for control, so that the self-adaptive grasping function of the three finger modules is realized, and meanwhile, the rotation of two finger modules in the three finger modules around the axis of the finger modules is ensured, the relative poses among the three finger modules are changed, and the grasping of different articles is realized;
