The drive motor is driven to rotate the feed shaft to move the bed to a position corresponding to the displacement to be compensated. The effect of the present invention is that, by using the preset interval parameters and the material displacement resident mathematics stored in the database, the displacement to be compensated corresponding to the selected preset interval parameter can accurately reflect the thermal displacement error. Further, the control module can be driven to move the bed to a position corresponding to the position to be compensated: and correct the thermal displacement error of the feed axis. [Embodiment] The above and other technical contents, features, and advantages of the present invention will be apparent from the following detailed description of the preferred embodiments. Referring to the circles 1, 2, and 3, the preferred embodiment of the feed shaft thermal displacement compensation method of the integrated processing machine of the present invention is applied to a comprehensive processing machine 2, which includes a machine base 21 and a The drive bearing housing 22 of the base 21 is further disposed on the base 21 and spaced apart from the drive bearing housing 22 by a support bearing seat 23, rotatably disposed along the axis L of the drive bearing housing 22 and a feed shaft 24 of the bearing block 23, a drive motor 25 that connects and drives the rotation of the feed shaft 24, and - is mounted to the feed shaft 24 and is rotatable along the axis L with the rotation of the feed shaft 24 % of moving beds. The compensation method includes the following steps 61 to 65. In step 61 af, the three temperature sensing stomach 3 is assembled to the drive bearing housing, the support bearing housing 23 and the bed 26 respectively adjacent to one side of the feed vehicle 24 . And the control module 4 of the data library 41 is further connected to the temperature sensor 3 and the control module 4, and the database 41 stores three preset interval parameters corresponding to different movement ranges of the bed table 26, The third is corresponding to the preset interval parameter to generate a plurality of displacement error mathematical equations to be compensated for displacement, and nine corresponding relative interval parameters and preset coefficients of the temperature sensors 3. In this example, the preset interval parameters respectively correspond to the area area Π and the area m in the map, and each preset interval parameter has a relative coordinate (relatively) and a relatively distant position of the adjacent (four) moving bearing housing 22, respectively. The maximum coordinate of the driving bearing housing 22, the mathematical equation of the displacement error is: 201242715 = z> gt-c where e is the displacement to be compensated for each of the preset interval parameters, «for the temperature sensor 3 The quantity, the temperature of A7; is corresponding to each preset interval parameter and temperature sensor difference, ~. Q is the corresponding preset interval parameter and the preset temperature of the temperature sensor 3; the temperature difference of each temperature sensor 3 is the temperature signal τ obtained by the temperature sensor 3 at the current sampling time and - the difference between the temperature signals obtained by the sampling time. Since the number of the temperature sensors 3 is three in this embodiment, the mathematical error of the displacement error is: ΔΓ, .ς+Δ^-^+ΔΤ; ^ where ΔΓ, ΔΓ2, Δ7; The temperature difference 'C, C2, C3 representing the relative temperature sensor 3 should be equivalent to the corresponding per-preset interval parameter and the preset coefficients of the temperature sensors 3. At step 62, 'the encoder 5 that is mounted to the drive motor and electrically connected to the control module 4 is measurable to the feed shaft 24 - the code position 1 that reflects the rotational position of the feed shaft 24, the control The module 4 calculates a current position of the bed 26 based on the worm position I. In step 63, the control module 4 compares the current position according to the preset interval parameters, and selects the corresponding current position in the parameter interval towel as the predetermined preset time zone. . In the embodiment of the present 201242715, the selected preset interval parameter is selected by determining whether the current position ^ falls on one of the preset interval parameters, and the current position falls within the preset interval parameter. The preset interval parameter is specified as the selected preset interval parameter between the minimum coordinate and the maximum coordinate of one of the minimum coordinates. In step 64, the control module 4 calculates a corresponding offset to be compensated based on the complex temperature signal T received by the displacement equation and the temperature sense (4) 3 corresponding to the selected preset interval parameter. At step 65, the control module 4 drives the drive motor 25 according to the (four) compensation displacement corresponding to the selected preset interval parameter, and rotates the feed shaft 24 to move the bed 26 to a position corresponding to the displacement to be compensated. . Since the placement positions of the temperature sensors 3 and the corresponding preset coefficients are first established in the database 41 through experiments, the corresponding displacement error mathematical formulas are used in different preset interval parameters. The displacement to be compensated is opposite to the thermal displacement error generated when the feed shaft 24 moves on the bed 26. Therefore, (4) the displacement to be compensated and the axis of the bed can be repaired. The thermal displacement error generated by the shaft 24 enables precise control of the position of the bed. . . It is worth mentioning that, in the integrated processing machine 2, the temperature sensing 3 may also be one, and is disposed in the driving bearing housing 22, the thrust bearing housing 23 and the bed 26. At the same time, the number of the preset coefficients should be equal to the preset interval parameter. In this case, the offset to be compensated corresponding to the selected preset interval parameter is equal to the temperature difference of the temperature sensor 3 and the corresponding preset should be selected. The product of the preset coefficient of the interval parameter, such as the thermal displacement error generated by 201242715 24, can also achieve the effect of correcting the feed axis. In summary, by storing the preset range 蓊:: displacement error mathematical formula of the 4 library 1 +, the displacement to be compensated corresponding to the selected preset interval parameter can accurately reflect the thermal displacement error, and thus can pass through the The control group 4 drives the bed 26 to move to a position 4 corresponding to the displacement to be compensated for correcting the thermal displacement error of the material to the shaft 24, so that the object of the present invention can be achieved. The above is only the preferred embodiment of the present invention, and the scope of the invention is not limited thereto, that is, the simple equivalent changes and modifications made by the scope of the invention and the description of the invention are All remain within the scope of the invention patent.
