Abstract

The invention discloses an electric mechanical gripper with a self-locking function. The electric mechanical gripper comprises a gear motor, a machine shell, a lead screw pair and two clamping jaw assemblies which are oppositely arranged. The lead screw pair comprises a lead screw and a lead screw nut, and a round pin shaft is arranged on the lead screw nut; the clamping jaw assembly comprises a clamping jaw, a sliding block and a V-shaped rod, the clamping jaw comprises the sliding block and clamping fingers, a containing groove is formed in the bottom of the sliding block, the V-shaped rod comprises a rod A and a rod B, the joint of the rod A and the rod B is hinged to the machine shell through a hinge shaft, the rod A extends into the containing groove and is provided with an inclined face, the rod B is provided with a guide groove, and a round pin shaft is slidably installed in the guide groove. The circular pin shaft is driven by the lead screw nut to move in the guide groove, so that the circular pin shaft drives the V-shaped rod to rotate around the center line of the hinge shaft, and the first end of the opening of the V-shaped rod pokes the sliding block. According to the invention, lead screw nut transmission is adopted, a self-locking function is realized, the gear motor can be prevented from entering a locking state, and the service life of the gear motor can be prolonged.

Description

technical field [0001] The invention belongs to the field of mechanical claws, and more specifically relates to an electric mechanical claw with a self-locking function and a method for judging a gripping object thereof. Background technique [0002] As we all know, robotic equipment has played an increasingly important role in helping people produce and live. With the development of science and technology, the use of robots in all walks of life has become more popular, and the mechanical arms and claws on robots are like human Hands, like hands, are an essential part of functioning. [0003] Mechanical claws can be divided into pneumatic mechanical claws and electric mechanical claws according to the driving power source. The clamping force of pneumatic mechanical claws is stable and greater than that of electric mechanical claws, but similarly, pneumatic mechanical claws are rigid in structure and large in size. , the noise is high, and it is difficult to control the spee...
