Description

Clamping assembly and mechanical arm Technical Field The utility model belongs to the technical field of mechanical arms, and particularly relates to a clamping assembly and a mechanical arm. Background The mechanical arm is highly flexible automation equipment, imitates part of functions of human arms, can execute accurate operation tasks in a plurality of fields such as industrial production, medical operation, scientific research, etc., and the mechanical arm generally can cooperate with the clamping component so as to clamp articles to the appointed position to finish a series of processing, but the shape of the general splint of the clamping component on the existing mechanical arm is certain, but the shapes of articles are different, the splint of a single shape is difficult to match with articles of different shapes, thereby leading to the clamping area of the splint to be smaller, and the phenomenon that the articles drop due to unstable clamping easily occurs. Disclosure of utility model In order to overcome the defects, the utility model provides the clamping assembly and the mechanical arm, and solves the problems that the clamping area of the clamping plate is small, and the phenomenon that the clamping is unstable and the object falls easily occurs because the clamping assembly on the existing mechanical arm is generally fixed in shape and the clamping plate with a single shape is difficult to match with objects with different shapes. The clamping assembly comprises a box body, wherein the top of the box body is provided with a mechanical arm body, the mechanical arm body is provided with a box body, one side of the box body is fixedly connected with a second motor, the output end of the second motor is fixedly connected with a bidirectional screw rod, the bidirectional screw rod is rotationally connected in the box body through a bearing, two movable plates are connected onto the bidirectional screw rod in a threaded manner, the bottom of the movable plate is fixedly connected with a connecting block, and the bottom of the connecting block is fixedly connected with a U-shaped frame; the U-shaped frame is characterized in that one side of the U-shaped frame is fixedly connected with a U-shaped plate, a T-shaped limiting rod is connected to the U-shaped plate in a sliding mode, a circular plate is fixedly connected to the T-shaped limiting rod, a spring is sleeved on the T-shaped limiting rod, a clamping plate is arranged in the U-shaped frame, a limiting hole is formed in the clamping plate, and one end of the T-shaped limiting rod extends to the inside of the limiting hole.
