Mechanical arm with precise positioning function

Abstract

The invention discloses a mechanical arm with a precise positioning function. The mechanical arm comprises a support, a base, an adjusting mechanism, a grabbing mechanism and a plurality of suction mechanisms, wherein the support comprises an upright support body and a cross support body which is horizontally connected to the upright support body in a sliding mode; the base is horizontally connected to the lower portion of the cross support body in a sliding mode, and an annular groove is formed in the lower surface of the base; the adjusting mechanism comprises an annular rotary base, three telescoping rods, a first disc and a sleeve; the grabbing mechanism comprises a cylinder, a compression spring, a second disc, two upright columns and a plurality of claw bodies, the cylinder is sleeved with the sleeve, the compression spring is arranged between the cylinder and the first disc, and a plurality of circular grooves are formed in the lateral side of any one claw body; each suction mechanism is arranged in one circular groove, and any one suction mechanism comprises a suction disc and a sliding plate. In the mechanical arm, when the cross support body moves in the vertical direction, the base moves in the horizontal direction, and the lengths of the three telescoping rods are adjusted, it is achieved that the position where the grabbing point of the grabbing mechanism is located is precisely adjusted in a multidirectional and multi-angle mode; therefore, the precise positioning function of the mechanical arm is achieved.

Description

technical field [0001] The invention relates to the field of mechanical technology. More specifically, the present invention relates to a precisely positioned robotic arm. Background technique [0002] Robotic arms have been widely used in industrial production sites, and can complete tasks such as welding, handling, assembling, and cutting. The use of robotic arms is of great significance to improving production efficiency and product quality, improving the working environment, ensuring human safety, and reducing production costs. [0003] Most of the robotic arms equipped with steering and lifting mechanisms in the prior art have problems such as large volume and complicated internal structure. Because of their huge volume and inflexible operation, it is difficult to complete the grasping work of objects in narrow spaces, and the grasping points The plane is relatively single, and the object cannot be precisely positioned; the mechanical arm with a simple structure has l...

[0003] Most of the robotic arms equipped with steering and lifting mechanisms in the prior art have problems such as large volume and complicated internal structure. Because of their huge volume and inflexible operation, it is difficult to complete the grasping work of objects in narrow spaces, and the grasping points The plane is relatively single, and the object cannot be precisely positioned; the mechanical arm with a simple structure has limited degrees of freedom, and has restrictions on the shape and size of the grasped object, which cannot meet the handling and assembly of objects from various angles, and cannot realize the positioning of objects. precise positioning of
