Embodiment Construction

[0015] The present invention will be further described below in conjunction with the accompanying drawings:

[0016] like figure 1 Shown is the extended posture of the flexible arm. A sleeve-type fully flexible mechanical arm driven by layers is composed of a telescopic flexible arm 1 , a frame 2 , and a slide rail 3 . Wherein, both the flexible arm 1 and the slide rail 3 are fixed on the frame 2 . There are 4 slide rails 3 in total, and they are symmetrically placed on the frame 2 in pairs.

[0017] like figure 2 As shown, it is a semi-compressed state where the flexible arm stretches out from the rubber tube 1-5 and the glass fiber 1-3 does not stretch out.

[0018] like image 3 As shown, the flexible arm 1 is composed of an end segment 1-1, a U-shaped card 1-2, a glass fiber 1-3, a middle segment 1-4, and a rubber sleeve 1-5. The end of each glass fiber 1-3 is locked on the end segment 1-1 by two U-shaped clips 1-2 at both ends of the end segment 1-1, and the middle...

Abstract

The invention discloses a layered drive sleeve-type full-flexible mechanical arm, and belongs to the field of industrial robots. The layered drive sleeve-type full-flexible mechanical arm comprises a flexible arm, a frame and two groups of sliding rails, wherein the flexible arm and the sliding rails are fixed onto the frame, the flexible arm is of a telescopic structure, the attitude of the flexible arm is controlled by the sliding rails, and the two groups of sliding rails are symmetrically placed on the frame. The attitude of the flexible arm can be controlled by layered drive, and obstacles can be avoided. More space can be saved by a telescopic function when the flexible arm is unused, and an annular hollow structure can be used for conveying materials and placing an electric wire, an air pipe and the like for controlling a top manipulator. The flexible arm is perfect in structural function, simple and reasonable in structure and high in practicability.

Description

technical field [0001] The invention relates to an S-shaped fully flexible mechanical arm, in particular to a retractable and hollow fully flexible mechanical arm structure. It belongs to the field of industrial robots. Background technique [0002] Robotic arms have been widely used in welding equipment and assembly manufacturing equipment at home and abroad. At present, the structure of most mechanical arms is driven by a rigid connecting rod combined with a motor at the rotating shaft. This structure has strong rigidity and stability, but requires a large space and low flexibility during movement. Compared with the traditional rigid articulated manipulator, the flexible manipulator has stronger human-computer interaction and higher flexibility, and can be used in various workplaces such as medical rehabilitation and agricultural picking. Contents of the invention [0003] The purpose of the present invention is to propose a sleeve-type fully flexible mechanical arm dr...
