Embodiment Construction

[0022] Embodiments of the multi-joint flexible robotic arm of the present invention will be described below with reference to the accompanying drawings. Those skilled in the art would recognize that the described embodiments can be modified in various ways or combinations thereof without departing from the spirit and scope of the invention. Accordingly, the drawings and description are illustrative in nature and not intended to limit the scope of the claims. Also, in this specification, the drawings are not drawn to scale, and like reference numerals denote like parts.

[0023] Most multi-joint robotic arms use joint motors to drive the movement of each joint. Therefore, each joint requires a joint motor, which has a complex installation structure and consumes a lot of power. However, the present invention provides a mechanical arm that can be driven by an electric push rod. Its power sources are arranged in a centralized manner and are small in number, which can drive the en...

Abstract

The invention provides a multi-joint flexible mechanical arm, comprising: a driving part, which drives a plurality of push rods to perform reciprocating linear motion; The pivot axis of the joint is perpendicular to the pivot axis of the lateral rotation joint, and the longitudinal rotation joint and the lateral rotation joint can rotate and stop around their respective pivots; pull wires, multiple pull wires pass through each rotation joint in turn from around the rotation joint, each The pull wires are individually connected to their corresponding push rods, and the other end of the pull wires passes through the frontmost rotating joint and is fixed; the brake is installed on each rotating joint; combined with the brake, the reciprocating linear motion of the push rod is used to tighten or loosen Pull the wire to control the rotation of the revolute joint. The joint motor is canceled, which reduces the complexity of the joint structure and power consumption; the telescopic detection device of the push rod can replace all the joint detection devices of the arm, reducing the cost.

Description

technical field [0001] The invention relates to the field of robots, in particular to a multi-joint flexible mechanical arm. Background technique [0002] The mechanical arm is one of the most commonly used robots in the industry. With the continuous improvement of the industrial level and requirements, the requirements for the robotic arm robot are also increasing. Robots with more degrees of freedom are flexible, thereby improving the scope of application and working space. Remote processing The ability to enter narrow and winding spaces for flaw detection and the ability to avoid obstacles is difficult for conventional robots to achieve. In addition, there is no need to disassemble the box body, and enter the interior through the peephole to check the operation of the machine or the cleaning and maintenance of key parts, and the sealing and testing of the curved pipe joints, minimally invasive technology. The snake-shaped multi-joint flexible arm is usually installed on ...
