Abstract

The invention relates to a wire-electrode cutting robot for machining a complex surface. According to the wire-electrode cutting robot for machining the complex surface, an arm of a series robot comprises a base, a waist, a large arm body, a small arm body, a wrist and a finger tip wire electrode holder, wherein the waist is installed on the base through a first bearing, a first servo motor is installed on the waist, the large arm body is connected with the waist through a second bearing, the small arm body is connected with the tail end of the large arm through a third bearing, one end of the wrist is connected with the tail end of the small arm body through a fourth bearing, and the other end of the wrist is connected with the finger tip wire electrode holder through a fifth bearing. According to the wire-electrode cutting robot for machining the complex surface, the structure of a machine tool can be simplified, a dimension chain can be shortened, and the advantages, of the series robot, that the working space is large, the control method is advanced, and the repeated positioning precision is high can be fully utilized.

Description

technical field [0001] The invention relates to the field of robots, in particular to a wire cutting robot for processing complex curved surfaces. Background technique [0002] At present, the existing multi-axis linkage wire cutting methods for complex curved surface parts are all researched on the basis of the traditional machine tool structure (cross table plus three-axis linkage auxiliary equipment). In the actual research and use, it is found that there are many problems in this method: in order to realize multi-axis linkage, it is necessary to design auxiliary linkage equipment, which not only increases the manufacturing cost, but also prolongs the dimensional chain, makes it more difficult to guarantee the machining accuracy, and limits the machining range , and the control methods are becoming more and more complex. With the continuous improvement of robot manufacturing level, control speed and accuracy, reliability, etc., and the continuous decline of manufacturing...
