Embodiment Construction

[0031] Further illustrate the present invention below in conjunction with accompanying drawing.

[0032] The five-degree-of-freedom mechanical arm includes a base 2, a base 3, a rear arm 4, a forearm 7, a wrist joint 8, and a palm 9. The base 2 is arranged on the bottom plate 1, and the base 3 is rotatably arranged on the base 2. Arm 4 is hinged on the base 3, one end of the forearm joint 6 and one end of the rear arm 4 are hinged on the same pivot on the base 3, the other end of the rear arm 4 is hinged with the forearm 7, the other end of the forearm joint 6 is hinged with the forearm One end of tendon 5 is hinged, and the other end of forearm tendon 5 is hinged with the rear end of forearm 7. The rear arm 4, forearm 7, forearm tendon 5, and forearm joint 6 form a parallelogram mechanism; the rear end of wrist joint 8 is rotatable Connected to the front end of the forearm 7, the palm 9 is rotatably mounted on the front end of the wrist joint 8;

Abstract

The invention discloses a five-degree-of-freedom mechanical arm. A substrate is arranged on a base-plate 1, a base is rotationally arranged on the substrate, and a rear arm is hinged on the base; one end of a front arm joint and one end of the rear arm are hinged on a same pivot shaft on the base, another end of the rear arm is hinged with a front arm 7, another end of the front arm joint is hinged with one end of a front arm tendon and another end of the front arm tendon is hinged with the rear end of the front arm, therefore, a parallelogram mechanism is formed by the rear arm, the front arm, the front arm tendon and the front arm joint; the rear end of a waist joint is rotationally connected at the front end of the front arm, and a palm is rotationally arranged at the front end of the waist joint. The five-degree-of-freedom mechanical arm provided by the invention has the advantages of being weight in self-suspension weight, stable to move and precise to control.

Description

technical field [0001] The invention relates to a mechanical arm, which is used in occasions such as welding, drilling, transporting, drawing graphics, and screwing. technical background [0002] The robotic arm technology used in industry is a high-tech formed by integrating various disciplines such as mechanism, informatics, sensing technology and automatic control. With the wide application of robotic arms in the industrial field, the design of robotic arms has been Continuous improvement and innovation, continuous improvement of performance such as control accuracy, stability and production efficiency, according to different applications, the design of the robotic arm is also varied. [0003] However, the existing mechanical arm has complex mechanism, heavy weight, clumsy movement, low transmission efficiency, and poor movement stability when there is an offset load. Contents of the invention [0004] The present invention overcomes the above-mentioned shortcomings of...
