a mechanical arm

Abstract

The invention discloses a mechanical arm, the structure of which includes a gripper, a support arm, a swing cylinder, a telescopic rod, and a fixed platform. The support arm is hinged to the gripper, the support arm is fixed above the swing cylinder, and the swing cylinder is integrated with the fixation platform. The telescopic rod is located above the swing cylinder, and the gripper is equipped with a connecting rod, a fixing mechanism, and a force rod. Through the fixing mechanism on the gripper, the cylindrical object is more stable during the handling process, and it is effective for controlling the power rod to the limit block. Push to make the limit block move on the moving groove. Since the transmission rod penetrates through the rotation block and the limit block is limited and engaged, the rotation block is fixed. Since the fixing mechanism is distributed on the handle in an isosceles triangle ring, According to the principle that the triangle is more stable, a more stable effect is achieved. The compression mechanism on the pressure block compresses the cylindrical object, making the left side of the rubber block into a sealed state, and the pressure becomes smaller, and then the force of the compression block plus the suction makes it Cylindrical objects are stronger.

Description

technical field [0001] The invention relates to the field of manipulators, in particular to a manipulator. Background technique [0002] Robotic arms are widely used in industrial manufacturing, medical treatment, space exploration and other fields. Although their shapes are different, they can all accept instructions and accurately locate a certain point in three-dimensional or two-dimensional space for operations. The robotic arm has the ability to carry It has the function of heavy objects, and can carry objects of various shapes. However, when the existing mechanical arm is carrying cylindrical objects, the shape of the cylindrical object is long, so it can only be carried by grasping the object column, but when carrying During the process, the sucker-type gripper has a low degree of adsorption and fit on the arc surface of the column body, resulting in poor gripping effect, and when the disc-shaped gripper is working, because the circular gripper is arc-shaped, it will ...
