Problems solved by technology

That is, a separate instrument device for measuring the bending amount of the column is provided on one side of the column, so the structure becomes complicated
In addition, since a distance sensor is used as a tool for measuring the amount of bending, it is impossible to accurately detect the amount of bending that is less than a few μm

Embodiment Construction

[0029] The following is combined with the attached Figure 1 to Figure 5 Preferred embodiments of the present invention will be described.

[0030] First, if figure 1 As disclosed, the present invention has a vertical column 30 extending from the machine tool body 10, a tool magazine 50 fixedly arranged on the front upper end of the column 30 along the direction of the processing area, and a tool magazine 50 fixed on the front upper end of the column 30 along the direction of the processing area on the machine tool body 10. The bed 20 at the front lower end of the column 30 is provided at a position facing the column 30 on the bed 20 and is tilted in the front-rear direction so as to be spaced apart from the column 30 . The workbench 60, and the control device that controls the various moving parts or parts of the machine tool.

[0031] The correction of the amount of bending of the bed 20 and the column 30 of the present invention is mainly performed by the control program ...

Abstract

The invention provides a method for correcting the bending amount of a column and a bed of a machine tool, comprising: the step of reading the weight of the tool magazine in the state where no tool is installed; the step of calculating the total weight of the tools installed in the tool magazine; The step of calculating the overall weight of the tool magazine with tools installed by summing the weight of the tool magazine and the sum of the tool weight; Comparing the bending amount of the corresponding column and the bed with the correction amount information to calculate the correction amount corresponding to the bending of the column and the bed; Steps that slope toward the direction the column bends.

Description

technical field [0001] The present invention relates to a method for correcting the bending of a column and a bed caused by the weight of a tool mounted on a column and a tool magazine in a horizontal machine tool. Background technique [0002] Recent machine tools have gradually increased their precision requirements. In addition, the junction area of ​​the machine tool tends to be simplified, while the function is gradually improved, and the requirements for improved precision are further increased. [0003] Among such machine tools, there is a machine tool provided with a vertical column and a tool magazine on which a weight is attached. In such machine tools, the column and the bed bend due to the weight of the tool magazine installed on the column in the direction of the machining area, thereby adversely affecting the machining accuracy of workpieces on the machining area. [0004] In particular, in a machine tool such as a horizontal type machining center in which to...
