Multipurpose robot

Abstract

A multipurpose robot comprises a movement platform, an operation mechanism, a clamping plate, a vertical electric rotation module, a horizontal motor rotation module and a connecting plate. A workpiece to be machined is fixed to the upper end face of the clamping plate, the bottom surface of the clamping plate is fixed to the upper end of the vertical electric rotation module, the lower end of the vertical electric rotation module is fixedly connected with an output shaft of the horizontal motor rotation module, the horizontal motor rotation module is fixed to the upper end face of the connecting plate, and an output shaft of the horizontal motor rotation module is parallel with the upper end face of the connecting plate. When an operation object is a special-shaped tube of which the center line is in a space shape or in a closed shape, the multipurpose robot has the advantages that the multipurpose robot only needs to determine the position of the center line of the tube part before operation without knowing the accurate position of the outline of the tube part, in the process of operating and moving around the tube part by a whole circumference, the needed freedom degree is small, the manufacturing cost is low, and using and maintaining are convenient.

Description

technical field [0001] The invention relates to the technical field of mechanical processing, in particular to a multipurpose robot. 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 pipe profile in ad...

[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
