The invention relates to an online compensation method for the coordinates of the running track of a robot, which belongs to the field of robots. Before the robot performs an operation, the shape and position data of the workpiece are read into the computer, and the computer transmits the coordinate data of the processed graphic elements of the section steel after compensation, and at the same time provides the basic processing graphic subroutine The coordinate variables of the graphic elements at the entrance are assigned values, and the computer performs data processing and calculation to compensate the previously set trajectory coordinates executed by the robot, so that the robot obtains the coordinates of the new processing operation trajectory. When the robot obtains the compensated After the data and the element coordinate data of the corresponding trajectory subroutine module, the robot main program detects the Boolean variable at the input port of each execution trajectory coordinate data subroutine module, and decides whether to execute the running trajectory coordinate data subroutine according to the value of the Boolean variable. The invention can obtain the running track coordinates online. The processed profile is allowed to have a large amount of deformation, and accurate processing dimensions can be obtained without rolling mill correction.

The invention provides a method for processing the hard surface of a screw drill and a device for realizing the method. The present invention first creatively designs the shape of the cemented carbide strip not to be a square, so that the gap between the cemented carbide strip and the cemented carbide strip is a curved shape, that is, the weld seam is a curved shape, so that when the mud and drilling fluid are eroded, Most of the force is decomposed to the hard alloy strip, which improves the wear resistance of the centralizer and TC bearing. The present invention also provides a positioning groove plate adapted to the rapid formation of the hard surface of the screw drill by the cemented carbide strip, the positioning groove plate is provided with a slot hole, and the shape of the slot hole is not square to match the shape of the cemented carbide strip , the positioning groove plate is used to arrange the carbide strips neatly and evenly according to the requirements, combined with the use of adhesive tape, it is simple and easy to realize the one-time bonding of a large number of cemented carbide strips, which greatly improves the bonding efficiency and improves the safety of manual operation. Different bonding angles, uneven bonding intervals, etc., improve the bonding accuracy, effectively guarantee and improve the wear resistance of the hard surface of the product.
