A multi-purpose robot with arc track

Abstract

The invention provides a multipurpose robot provided with an arc track. The multipurpose robot comprises a connecting part, the arc track, a drive mechanism, a telescopic mechanism, working arms and working heads. Rotational freedom degrees are adopted in the connecting part and the arc track. The axis of a rotating shaft is perpendicular to a plane where the center line of the arc track is located and is located in the middle of the arc track. The working arms can move along the arc track under driving of the drive mechanism. The working heads can telescope under driving of the telescopic mechanism. When a manipulating object is a special pipe with the center line in a space shape or in a closed shape, the multipurpose robot provided with the arc track has the advantages that before operation, only the position of the center line of the pipe needs to be definite, it is unnecessary to know the accurate position of the outline of the pipe, few freedom degrees are needed by operation motion around the pipe by a whole circle, the manufacturing cost is low, and use and maintenance are convenient.

Description

technical field [0001] The invention relates to the technical field of mechanical processing, in particular to a multipurpose robot with an arc track. Background technique [0002] With the development of automation equipment and robot technology, various coordinate machine tools, machining centers and articulated industrial robots have come out one after another, and gradually formed two types of general motion platforms, coordinate type and articulated type, and the connections at the ends of these two types of motion platforms are different. The job head can complete various job tasks. [0003] However, for pipe fittings, these two types of general-purpose motion platforms have the following disadvantages: First, the movement of the entire week is complex, requiring more than three degrees of freedom to be linked to complete; second, these two types of motion platforms use spatial coordinate data To drive the working head, it is necessary to know the precise size of the ...

[0003] However, for pipe fittings, these two types of general-purpose motion platforms have the following disadvantages: First, the movement of the entire week is complex, requiring more than three degrees of freedom to be linked to complete; second, these two types of motion platforms use spatial coordinate data Drive the working head to work, so it is necessary to know the precise size of the pipe contour in advance; third, because the working head needs to achieve a precise spatial position, each degree of freedom of these two types of motion platforms is required to have high precision, so the cost is high
