Embodiment Construction

[0053] Include the following steps:

[0054] Step 1. Establish the coordinate system X-Z-B-C of the machine tool, wherein the X axis is parallel to the movement direction of the machine tool workpiece spindle, the Z axis is parallel to the movement direction of the machine tool system 2, the B axis is the rotation axis of the machine tool turntable 12, and the C axis is the rotation axis of the machine tool workpiece spindle ;

[0055] Step 2. After each axis of the machine tool returns to the reference point, adjust the turntable so that the tool system axis 207 is parallel to the Z axis, install the calibration plate 1 on the tool system 2, and use the dial indicator I8 to assist in detection so that the plane 101 on the calibration plate is parallel to the X axis parallel:

[0056] Step 3: Pass the center punch 701 through the magnetic base 702, relative to the rotation axis of the workpiece spindle, and eccentrically adsorb it on the end surface 601 of the workpiece spind...

Abstract

The invention discloses a horizontal precise polishing machine tool workpiece main shaft and tool system centering method, and belongs to the field of mechanical manufacturing. The method comprises calibration adjustment in vertical and horizontal directions; in the vertical direction, a center punch scoring calibration plate eccentrically arranged relativeto a revolving center of a workpiece main shaft is adopted; and a coordinate of the workpiece main shaft relativeto an X-axis reference point of a machine tool in a specific position is mainly obtained through horizontal centering. The calibration plate and a calibration semisphere used in the whole centering process consist of simple geometries, so that the machining difficulty is low, the machining is precise and easy to be controlled, the manual clamping adjustment requirement is low, the repeated operability is good, and the error can be gradually reduced through multiple times of operations; a common dial indicator and a laser precise amesdial are adopted in measurement; the installation and the adjustment are flexible; the influence from machine layout is low; the generality is good; and the measurement precision is high. Compared with the use of a tool setting gauge or other special equipment, the method has the advantages of simple operation, convenience for installation and debugging and low manufacturing cost.

Description

technical field [0001] The invention belongs to the field of mechanical manufacturing, and in particular relates to a centering method for a workpiece spindle and a tool system of a horizontal precision grinding and polishing machine tool. Background technique [0002] The motion accuracy and assembly accuracy of the components of the machine tool have a great influence on the machining accuracy of the parts. With the improvement of manufacturing technology, all components used in CNC machine tools can guarantee high motion accuracy, but high-precision moving parts are not the only guarantee for high-precision machine tools, and the installation and debugging accuracy of machine tools are often more decisive. . When programming a CNC horizontal grinding and polishing machine tool, no matter whether absolute programming, incremental programming or mixed programming is used, it is required that the center of the spindle clamping the workpiece and the center of the tool system...
