The measuring method is to install a displacement sensor at the end of the feed shaft. The displacement sensor is used to measure the heating of the feed shaft. The thermal deformation information generated at the tail end, through the thermal deformation information, compensates for the error in moving the bed. However, because the degree of thermal deformation of the feed axis at different parts is not the same, only the thermal deformation information measured by the tail end of the feed axis is insufficient, and the movement error of the bed is fully reflected. The bed still has considerable errors after compensation. Therefore, another method for measuring the feed axis thermal displacement of another processing machine, as shown in Japanese Patent Laid-Open No. H11-254272, is to provide a plurality of temperature senses on a bed that is mounted on a moving axis and moved. The detector measures the temperature, and the temperature data is input to the operator unit for analysis, and the sound is compensated by the error caused by the temperature when moving. The temperature measurement of the material is quite far from the feed axis. Because of the error, the temperature of the feed and the temperature actually received by the feed axis still have the same error. accurate. 201242706 SUMMARY OF THE INVENTION Accordingly, it is an object of the present invention to provide a feed axis thermal displacement measurement method for an integrated processing machine.

Referring to Figures 1, 2 and 3, the preferred embodiment of the feed axis thermal displacement measuring method of the integrated processing machine of the present invention is applied to a comprehensive processing machine 2, which includes a base 21 and a setting. a driving bearing housing 22 of the base 21, a supporting bearing seat 23 disposed at the housing 21 and spaced apart from the driving bearing housing 22, and rotatably passing through the driving bearing housing 22 along an axis L and A feed shaft 24 of the pedestal holder 23, a drive motor 25 that connects and drives the rotation of the feed shaft 24, is mounted to the feed shaft 24 and is rotatable along the axis L with the rotation of the feed shaft 24. a moving bed table %, and a spindle holder 27 disposed above the frame 21, the spindle holder 27 having a moving part field located above the bed 26 and movable in a vertical direction relative to the bed 26 The following three steps are included in the step 81, the three temperature sensors 3 are respectively located on the drive shaft "the seat. The support bearing block 23 and the bed 26 are adjacent to the feed axis 4 - side. In the present embodiment, the temperature sensors 3 are commercially available as temperature sensors numbered AD590. In step 82, three test bars 4 that can be linked by the bed 26 are disposed along the direction of the axis L in the direction of the bed, and the phase needles enter the ab λα * and the test bars are 5 hai 4: storing a plurality of preset positions of the reference position, and storing a control of the moving module 271 along the vertical direction z, 叮 罝 ° ° Z of the control module 5 of a 201242706 曰; The moving path of the test bar 4 is provided with a bucket for measuring the stem and the relative stick 4, and a method for shifting the sensor. In the present embodiment, the displacement sensor 6 is mounted on the 5, ,, the sanding member 271, and the eddy current sense is the position of the driving bearing housing 22 in the soil position. In step 83, the control module 5 controls the moving member 271 to drive the displacement sensor 3 along the vertical axis & 7 ± phase... (10) direction Z moves upward (See Fig. i for the fake, go to the selected position and drive the drive horse to drive the 4 bed 26 to move the corresponding test bar to position 'finally control the moving member 271 to drive the displacement sensor 6 toward The blank is adjacent to the corresponding test bar 4.
