The present application provides a method for measuring the axis of a turntable, which may include: determining a first point on the rotation axis of the machine tool according to a plurality of first sphere centers of a standard sphere at different positions on a first plane determined by a sensor; The center of a sphere is on the first circle, and the center of the first circle is the first point; according to the plurality of second sphere centers of the standard sphere at different positions on the second plane determined by the sensor, determine the The second point on the rotation axis; the centers of the second spheres are on a second circle, and the center of the second circle is the second point; the height of the second plane is the same as the height of the first plane different; the axis of rotation is determined from the first point and the second point. The embodiment of the present invention can effectively measure and determine the axis of the machine tool turntable and ensure the machining accuracy.
Description
technical field [0001] The application relates to the field of machine tool processing, and in particular, to a method and device for measuring the axis of a turntable. Background technique [0002] With the improvement of the machining accuracy requirements of machine tool workpieces, completing the accurate machining of workpieces is the goal pursued in the field of CNC machine tools. The axis of each axis of the machine tool affects the machining accuracy of the machine tool. [0003] The axis of the machine tool needs to be adjusted before processing to ensure subsequent processing accuracy and processing efficiency. CNC machine tools need to align the axis of the machine tool before processing, and it is necessary to calibrate the axis data of the rotation center of the turntable. Usually, the probe and the standard ball are used to calibrate the axis of the turntable, or the dial gauge is matched with the test rod. However, the precision of the dial indicator and the...
