FIG. 2 is a schematic view of the overall structure of the present invention;

fig. 3 is a circuit diagram of the present invention.

In the figure: the device comprises a frame 1, an 11 mounting groove, a 12 limiting sliding groove, a 13 positioning pin, a 14 connecting groove, a 2 rack, a 21 threaded hole, a 3 clamping jaw, a 31 arc-shaped groove, a 32 bearing, a 33 gear and a 4 motor.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Please refer to fig. 1, a clamping jaw mechanism of a vision positioning robot, includes a frame 1, a positioning pin 13 is symmetrically and threadedly connected to the surface of the frame 1, a mounting groove 11 and a connecting groove 14 are respectively connected to two ends of the frame 1, the connecting groove 14 is used for connecting a robot arm, a limiting sliding groove 12 is arranged inside the frame 1 between the mounting groove 11 and the connecting groove 14, the limiting sliding groove 12 limits a rack 2, an inner side of the limiting sliding groove 12 is slidably connected with the rack 2, a gear 33 is rotatably connected to the surface of the inner side positioning pin 13 of the mounting groove 11, a clamping jaw 3 is arranged on the surface of the gear 33, and the rack 2 is engaged with.

Referring to fig. 1, a threaded hole 21 is formed in the inner side of the rack 2, and the threaded hole 21 drives the rack 2 to move along the limiting sliding groove 12 when the motor 4 drives the rotating shaft to rotate, so that the rack 2 is meshed with the connecting gear 33 to drive the gear 33 to rotate to control the clamping jaw 3 to grab an object.

Referring to fig. 1, the motor 4 is installed inside the connecting groove 14, and the type of the motor 4 is: DMBR-08E, the rotating shaft of the motor 4 is connected with the inner side of the threaded hole 21 in a threaded manner, and the surface of the rotating shaft of the motor 4 is a 20-step screw rod motor provided with threads.
