Abstract

The invention discloses a mechanical claw with an adjustable number of claws, which comprises the end of the mechanical arm and an end shell, a cavity is arranged inside the end shell, a support shaft is arranged in the middle of the end shell, and the support The shaft is arranged concentrically with the end shell; the switching assembly includes a first arc block, a second arc block and a third arc block, and the first arc block is arranged between the support shaft and the end shell Between the support shaft and the end shell; the inner wall of the end shell is provided with a side ring groove corresponding to the position of the first arc block, and the outer surface of the second arc block and the third arc block are embedded in the In the side ring groove; the fourth arc-shaped block, the fourth arc-shaped block is arranged in the cavity; the engaging assembly includes a replacement part and a claw, and the claw is connected to the switching assembly shaft, so The replacement part is connected to the end of the end shell, and the replacement part is provided with a driving part to connect the claws; the mechanical claw of the present invention can adjust the number of claws to adapt to the shape of the grasped object.

Description

technical field [0001] The invention relates to the technical field of mechanical devices, in particular to a mechanical claw with adjustable number of claws. Background technique [0002] The mechanical claw refers to a high-precision, high-speed glue dispensing robot arm. The mechanical claw is a complex system with multiple inputs and multiple outputs, a high degree of nonlinearity, and strong coupling. Because of its unique operational flexibility, it has been widely used in industrial assembly, safety and explosion-proof fields. [0003] Mechanical claws are usually used to grab items, especially in the automatic production line. When grabbing items in the production line, the shape of some items will make it difficult for the mechanical claws to grab the number of front claws. For example, cube items, three The mechanical claws of claws are difficult to grasp, so it is necessary to design a mechanical claw that is easy to change the number of claws to meet the graspin...
