Method for simply positioning machine tool turntable rotation axis

Abstract

The invention provides a method for simply positioning the machine tool turntable rotation axis and belongs to the field of machine tools. The invention provides the method for simply positioning therotation axis of the machine tool turntable. The rotation axis of the machine tool turntable is positioned by means of an auxiliary ball and a dial indicator. The method comprises the following steps:1, determining and moving a main shaft to roughly-adjusted turntable coordinates; 2, placing the dial indicator on the turntable, and enabling a contact of the dial indicator and the auxiliary ball to be in light contact and equal in height; 3, determining and moving the main shaft to corrected rotation axis coordinates; 4, judging whether the difference between Bmax and Bmin is smaller than or equal to 0.002 mm or not, if not, entering the step 2, and if yes, entering the step 5; and 5, determining the coordinates of the main shaft through a magnetic attraction base and the auxiliary ball toobtain the origin of the turntable coordinates, and establishing a rectangular coordinate system positioning axis. The method is convenient to operate, has no technical requirements on operators, consumes short time in a whole implementation process, and has very high practicability and universality.

Description

technical field [0001] The invention relates to a method for positioning an axis, in particular to a method for conveniently positioning the rotation axis of a turntable of a machine tool, which belongs to the field of machine tools. Background technique [0002] In CNC machine tools, it is very important to precisely position the axis of rotation of the rotary axis. Especially when using ballbar, R-test and other tools to detect the error of the rotation axis, the precise rotation axis can improve the accuracy of the entire error detection. [0003] In the prior art, most of the methods for positioning the rotation axis of the turntable require skilled technical operations and rich experience, so as to achieve high positioning accuracy. Some methods require the use of gauge blocks, but the gauge blocks are often heavy in quality, and it is extremely difficult to meet the required requirements in the process of fine adjustment, which increases the difficulty and complexity ...
