When the welding robot is calibrated, on the one hand, when the end of the welding wire is used as the tool point, due to the certain elasticity of the welding wire, it will deviate from the center line of the welding torch after leaving the contact tip, and the length of the protruding welding wire is difficult to determine intuitively, resulting in the inaccuracy of the welding torch tool point. Accurate, on the other hand, different welding torch postures need to be used for welding torch tool point calibration, and there is no effective means to ensure the accuracy of the contact when touching a fixed point. It is difficult to ensure the accuracy and effect of tool point calibration, which affects the off-line programming of welding robots. apply effects

Abstract
The invention discloses a device for calibrating a welding gun tool point of a welding robot. The device comprises a welding gun sleeve plate, a lateral screw, fixing screws, a welding wire simulationrod and a calibrating target; the cross section of the welding gun sleeve plate is of a blind loop structure, the top of the welding gun sleeve plate is open, the bottom of the welding gun sleeve plate is closed, the welding wire simulation rod capable of rotating up and down is arranged in the center of the bottom of the welding gun sleeve plate and is provided with a thread, and the end part ofthe simulation rod is spherical; the simulation rod can rotate for position adjustment; one side of the welding wire simulation rod is provided with the lateral screw, and when the welding wire simulation rod is rotated to the set position, the lateral screw fixes the position of the welding wire simulation rod; the multiple evenly-distributed fixing screws are arranged on the side face of the welding gun sleeve plate and used for fastening the welding gun sleeve plate to the welding gun; and the calibrating target is provided with a calibrating groove which is conductive when making contactwith the welding wire simulation rod, the calibrating groove communicates with at least three conductive strips arranged on the calibrating target, each conductive strip is connected with an indicatorlight, and the multiple indicator lights are connected with a power supply to form a loop.
Description
Technical field [0001] The invention belongs to the technical field of robot welding, and relates to a device and a method for point calibration of a welding robot welding gun tool. Background technique [0002] Industrial robots are one of the important basic equipment for the implementation of automated production lines, Industry 4.0, smart manufacturing workshops, digital factories, and smart factories. According to incomplete statistics, nearly half of the industrial robots in service around the world are used in various forms of welding processing. [0003] Offline programming and simulation of robot welding is one of the important systems to improve the intelligence of the robot welding system, and it is an important part of the intelligent welding robot software system. The performance of off-line programming tasks is closely related to the calibration accuracy of the robot welding gun. When the welding robot is calibrated, on the one hand, when the end of the welding wire...
