Problems solved by technology

[0004] There are the following disadvantages in the prior art: the lower chassis of the robot has a large range of motion, and the middle rotating shaft must realize both rotation and a large expansion and contraction space. At present, splines and hexagonal prisms are mainly used. high sliding frictional resistance

Abstract

The invention discloses a large telescopic double-cross joint rotation shaft of a parallel robot. The large telescopic double-cross joint rotation shaft of the parallel robot is mainly composed of three parts, namely the upper cross cardan joint (1), the lower cross joint (9) and the middle telescopic rod assembly. The large telescopic double-cross joint rotation shaft is characterized in that the telescopic rod assembly comprises a connection top plate (2), a first hollow optical shaft (3), a second hollow optical shaft (5), a third hollow optical shaft (8), a linear bearing (6), a middle connection plate (4) and a lower connection plate (7). The first hollow optical shaft (3) and the second hollow optical shaft (5) are fixed between the connection top plate (2) and the lower connection plate (7) in parallel. One end of the third hollow optical shaft (8) is fixed to the center of the middle connection plate (4) and the other end of the third hollow optical shaft (8) and the lower cross joint (9) are fixed together. As the hollow optical shafts and the linear bearing are adopted, the overall telescopic amount is large, rolling friction is adopted in the linear bearing and resistance is greatly lowered.

Description

technical field [0001] The invention belongs to the technical field of parallel robots, and in particular relates to a large telescopic double cross joint rotary shaft of a parallel robot. Background technique [0002] In the industry, industrial sorting robots are often used for secondary packaging and material sorting, also known as DELTA parallel robots academically. Parallel robots have been widely used in fields that require high stiffness, high precision, or large loads without a large workspace, and have become important assistants in the industrial field. [0003] The rotation axis is the geometric straight line on which the rotational symmetry action is performed. When the rotation action acts on the image, the vertical distance between any point in the image and the rotation axis (line) is required to remain constant. The telescopic double rotary axes in the parallel robot are used to connect the driving arm to control the range of motion of the driving arm. With...
