SUMMERY OF THE UTILITY MODEL
The utility model provides a robot clamping jaw capable of stably grabbing, and the defects are overcome.
The utility model is realized by the following steps:
grab stable robot clamping jaw, include
The fixing part is used for being connected to the robot arm;
the connecting frame is connected below the fixing part and is of a regular polygon structure, and each edge of the connecting frame is correspondingly connected with one clamping part; and
a plurality of clamping parts connected to the fixing part and the connecting frame;
the fixing part drives the connecting frame to move up and down to realize that each clamping part is opened and closed simultaneously so as to realize clamping operation.
Further, the fixed part includes the mounting bracket, the top of mounting bracket links to each other with the robot arm, and servo motor installs the inside of mounting bracket, servo motor's main shaft sets up downwards and links to each other with a lead screw, the link with lead screw screwed connection.
Furthermore, the clamping part comprises a connecting block, the upper end of the connecting block is connected to the mounting frame, the lower end of the connecting block is rotatably connected with a connecting plate, and two ends of the rotating block are hinged to the edge of the connecting frame and the middle of the connecting plate respectively;
the lower end of the connecting plate is connected with a clamping plate.
Further, the number of sides of the connecting frame is at least 3.
Compared with the prior art, the utility model has the beneficial effects that:
the part can be gripped from many angles simultaneously to technical scheme more than adopting, and the part center is found accurately in the automation, has the centre gripping reliable and stable, improves the result of use.

Detailed Description
To further illustrate the technical means and effects of the present invention adopted to achieve the intended purpose of the utility model, the following detailed description is given for the specific embodiments, structures, features and effects of the present invention in conjunction with the accompanying drawings and preferred embodiments.
Referring to fig. 1 and 2, a robot gripper for stable gripping includes a fixing portion 1 for connecting to a robot arm;
the connecting frame 2 is connected below the fixing part 1, the connecting frame 2 is of a regular polygon structure with at least more than 3 sides, the figure is a regular polygon 1, and each side is correspondingly connected with one clamping part 3; and
4 clamping parts 3 connected to the fixing part 1 and the connecting frame 2;
the fixing part 1 drives the connecting frame 2 to move up and down to realize that each clamping part 3 is opened and closed simultaneously to realize clamping operation.
Referring to fig. 2, the fixing portion 1 includes an installation frame 1a, the installation frame 1a includes two plates 1aa arranged up and down, the plates 1aa may be circular or rectangular, the two plates 1aa are connected by a plurality of connecting rods 1ab to form a shape close to a cylinder, the interior of the cylinder is hollow, the upper portion of the installation frame 1a is connected with a robot arm, a servo motor 1b is installed inside the installation frame 1a, a main shaft of the servo motor 1b is arranged downward and connected with a screw rod 1c, and the connection frame 2 is spirally connected with the screw rod 1 c.
