A robot system for complex curved surface processing

Abstract

The invention provides a robot system for complex curved surface processing, including: a robot equipped with a wire feeding mechanism and a working fluid circulation device; moving; the electromagnetic suction table is used to place and rotate the object to be processed; the electric control system is used to electrically connect the robot, the electromagnetic suction table and the ground rail assembly; the electric control system controls the The robot and the ground rail assembly move to the preset position, and control the rotation of the electromagnetic suction table to cooperate with the robot to cut the object to be processed, aiming to provide a full range of layout for curved surface processing, which is convenient for the robot to cut time operation.

Description

technical field [0001] The invention relates to the field of robot processing, in particular to a robot system for complex curved surface processing. Background technique [0002] Existing wire electric discharge cutting is divided into two types according to the form of workbench: single column cross table type and double column type. The machine tool structure is precise, the processing process is stable and the surface quality is good. The form of the machine tool, the degree of freedom of processing is limited, generally through the movement of the worktable in the X, Y axis to realize the plane processing of the workpiece, it is almost impossible to realize the processing of multi-curved surfaces or multi-angle cutting; secondly, the machine tool structure is heavy and cannot be realized The main reason for multi-degree-of-freedom processing, but this type of wire-cutting machine tool is the mainstream form of wire-cutting machine tools at present, so the current wire-c...

[0002] Existing wire electric discharge cutting is divided into two types according to the form of workbench: single column cross table type and double column type. The machine tool structure is precise, the processing process is stable and the surface quality is good. The form of the machine tool, the degree of freedom of processing is limited, generally through the movement of the worktable in the X, Y axis to realize the plane processing of the workpiece, it is almost impossible to realize the processing of multi-curved surfaces or multi-angle cutting; secondly, the machine tool structure is heavy and cannot be realized The main reason for multi-degree-of-freedom processing, but this type of wire-cutting machine tool is the mainstream form of wire-cutting machine tools at present, so the current wire-cutting technology has the problems of single processing and limited scope of application

[0003] Patent CN103752967B adopts the arrangement of the whole clamping and transporting mechanism at the position of the end flange, which will cause the end to bear too much weight and reduce the accuracy; at the same time, it uses two guide wheels to reciprocate the electrode wire, so that It will cause the phenomenon of overlapping wires, so that the electrode wires cannot be kept in a tight state, and the wires are easily broken during actual processing

[0004] Patent CN106925853A designed a wire-cut robot device with a variable wire gripper, but its structure is too complicated and heavy, which affects the processing accuracy; and it only uses a four-axis robot, which seriously limits the advantages of the robot; this patent focuses on variable The wire clamp does not have a comprehensive layout of the major systems required for wire cutting, and it cannot actually be called a wire cutting robot.
