Description
Technical Field
The invention relates to a center calibration device of a polishing tool.
Background
In robot programming, it is generally necessary to define an operation task on a workpiece under a tool coordinate system of a robot, and therefore, before machining the workpiece, it is necessary to determine in advance a relationship between the tool coordinate system fixed on the tool and a flange coordinate system where an end joint of the tool is fixed, that is, to perform calibration of the tool coordinate system. The calibration of the tool coordinate system is to determine the coordinate of the tool center point in the flange coordinate system and the coordinate axis direction of the tool coordinate system relative to the flange coordinate system. The tool coordinates are convenient for controlling the robot to move towards the set coordinate direction, the gesture of the robot is set, and the motion path is planned. The precision of tool coordinate calibration influences the precision of the position and the gesture of the robot, so that the polishing effect is influenced. The tool coordinate accuracy of the robot in offline programming is a necessary condition for the track accuracy.
In the existing tool center point calibration method, the difficulty of the four-point method is that the finding of the tool center point must be completed by manual operation. Because the sander moves eccentrically, the center point of the tool is difficult to find when the sander is stationary, and the error is easily excessive. Therefore, the existing tool center point calibration technology is complex in operation and poor in precision.
