Problems solved by technology

However, the biggest problem with the above-mentioned robotic arm is that it is difficult for the robotic arm itself to bend at any angle.
Although a certain bending function can be achieved through the link mechanism, this mechanism is only suitable for larger mechanical arms. For some small precision products, the structure of the link mechanism is complicated and difficult to adapt

Embodiment Construction

[0028] The present invention will be further described below in conjunction with specific embodiments and accompanying drawings.

[0029] See Figure 1-9 As shown, the present invention is a serpentine mechanical arm, which consists of an arm body 10, a driving part 20 and a connecting part 3, wherein the connecting part 3 is located between the arm body 10 and the driving part 20, and the driving part 20 is fixedly connected to the rear end of the connection part 3 , and the arm body 10 is connected to the front end of the connection part 3 . The arm body 10 is driven by the driving part 20 to realize bending and swinging.

[0030] See figure 1 , 2 , 3, the arm body 10 is formed by a plurality of joints 1 connected to each other. In this embodiment, five joints are used, and two adjacent joints 1 can have two degrees of freedom in the up, down and left and right directions. The first joint is directly fixedly connected to the connecting part 3, and the last joint is used ...

Abstract

The invention discloses a serpentine mechanical arm. The arm body of the serpentine mechanical arm is formed by connecting a plurality of bone sections moveably in sequence. Two adjacent bone sections of the arm body are connected by a universal joint pin. The two adjacent bone sections swing freely up and down and left and right through the universal joint pin and swing up and down and left and right with corresponding bone sections through traction drive of two groups of traction lines and drive and the matching of bone sections. The serpentine mechanical arm provided by the invention is designed by simulating a serpent. The combined part of the two adjacent bone sections has two degrees of freedom, one of which is driven by double motors, respectively. Swing of a single bone section is superposed to form swing of the whole mechanical arm in any directions, and the mechanical arm can bend at any angle. The mechanical arm can bend in a three-dimensional spatial curve. According to the serpentine design provided by the invention, combination of the whole mechanical arm is compact as far as possible, and meanwhile the mechanical arm has enough and relatively large bending range.

Description

Technical field: [0001] The invention relates to the technical field of mechanical automation products, in particular to a serpentine mechanical arm capable of rotating and twisting in any direction. Background technique: [0002] In the process of automatic production and processing, it is often necessary to use robotic arms to complete some tasks. Common robotic arms include the following methods: [0003] The first one is to use the X / Y / Z three-axis operating mechanism, that is, the mechanical arm is installed on a platform with X / Y / Z three-axis superimposed operation, and the platform moves in the X / Y / Z direction to drive The robotic arm realizes the operation in three-dimensional space. [0004] The second type is to add a rotating mechanism on the basis of the above-mentioned first type, so as to increase the operation in one rotation direction. [0005] The third is to use a link mechanism, that is, the mechanical arm is pivotally connected with multiple links, and ...
