High-rigidity and anti-deformation hydraulic driving mechanical arm

Abstract

The invention discloses a high-rigidity and anti-deformation hydraulic driving mechanical arm which comprises a rotating base, a large arm body, a second arm body, a third arm body, a wrist and a handgrip. The rotating base is driven by rotating motors to rotate, and the rotating base is hinged to the large arm through a hinging point; the large arm can achieve vertical pitching movement and is hinged to the second arm body; through stretching-out and drawing-back of a hydraulic cylinder, the second arm body makes pitching movement around the large arm; the second arm body is slidably connected with the third arm body, and through stretching-out and drawing-back of the hydraulic cylinder, the third arm body makes linear movement; and the third arm body is hinged to the wrist, the tail endof the wrist is connected with the hand grip, and the hand grip can rotate around the wrist. Through pitching and swing movement of the rotating base, the large arm body, the second arm body, the third arm body and the wrist, grabbing and loosening of the hand grip in any position in the space can be finally achieved.

Description

technical field [0001] The invention relates to a mechanical part, in particular to a high-rigidity anti-deformation hydraulically driven mechanical arm. Background technique [0002] With the development of technology, robotic arms are widely used in industrial production and construction industries due to their flexibility. The operability of the manipulator directly affects the stability and grasping accuracy of the manipulator when grabbing the workpiece. If the operation is inconvenient, it will affect the actual use effect, reduce the application range, or the workpiece will be stuck and cannot be effectively grasped during the action. Therefore, the requirements for the movement of the robotic arm and the flexibility of the grip of the robotic hand are very high. In the prior art, the mechanical arm usually uses a heavy one-piece plate to ensure its rigidity. Because of its heavy weight, its working speed slows down. At the same time, the mechanical grip is generall...

AI Technical Summary

Problems solved by technology

In the prior art, the mechanical arm usually uses a heavy one-piece plate to ensure its rigidity. Because of its heavy weight, its working speed slows down. At the same time, the mechanical grip is generally connected to the end of the mechanical arm, which affects production efficiency.
