In addition, the present invention provides a method for detecting the geometric accuracy of an intelligent digital geometry of a machine tool, which is used for detecting the geometric accuracy of an object 200 to be detected, as shown in fig. 1 to 6, the method for detecting the geometric accuracy of the intelligent digital geometry of the machine tool comprises the following steps:
a device setting step S1: the precision measuring device 10 is movably disposed on the object 200, and the distance measuring device 20 is disposed at one side of the precision measuring device 10. As shown in fig. 1, the precision measuring device 10 is disposed on the sliding block 131, and the sliding block 131 enables the precision measuring device 10 to be movably disposed on the object 200 to be measured, in more detail, the sliding block 131 also enables the precision measuring device 10 to automatically move on the track 132 through the driving device, thereby achieving the purpose of automatic measurement. In the embodiment of the present invention, the user can move the slide 131 manually to move the precision measuring apparatus 10 on the track 132.
A measurement information setting step S2: the user sets a measurement data 311 by using the measurement setting module 31 of the data processing apparatus 30. As shown in fig. 5, the measurement data 311 includes measurement start point data 311a, measurement end point data 311b, measurement recording point data 311c, and measurement point allowable error value data 311 d. The user can set the measurement start point data 311a, the measurement end point data 311b, the measurement recording point data 311c, and the measurement point allowable error value data 311d through the measurement setting module 31, and the precision measurement device 10 and the distance measurement device 20 receive the measurement start point data 311a, the measurement end point data 311b, the measurement recording point data 311c, and the measurement point allowable error value data 311d, so as to obtain the range to be measured and the distance point to be recorded.
For example, the user may set the measurement start point data 311a to be 0 mm, the measurement end point data 311b to be 300 mm, the measurement record point data 311c to be 0 mm, 100 mm, 200 mm and 300 mm (every 100 mm) and the measurement point allowable error value data 311d to be plus or minus 1 mm, the precision measuring device 10 and the distance measuring device 20 receive the data to know that the range to be measured is from the position of the measurement distance value of 0 mm to the position of 300 mm, and when the distance measuring device 20 measures that the precision measuring device 10 moves to the positions of the measurement distances value of 0 mm, 100 mm, 200 mm and 300 mm, the precision measuring device 10 will measure the true degree and the horizontal degree of the object 200.
A correction step S3: a first spacing distance D1 is equal to a second spacing distance D2. As shown in fig. 3, the standard object 112 of the precision measuring apparatus 10 is disposed at one side of the sliding module 13, the first spacing distance D1 and the second spacing distance D2 are distances between the head and the tail of the rail 132 of the sliding module 13 and the head and the tail of the standard object 112, respectively, and the calibration step S3 makes the first spacing distance D1 equal to the second spacing distance D2, so that the rail 132 is parallel to the standard object 112, and the subsequent precision measuring apparatus 10 is convenient to measure the straightness of the object 200 to be measured.

As shown in fig. 1 to 6, taking the embodiment of the present invention as an example, the movement of the precision measuring device 10 is controlled by a user, the user moves the straightness measuring module 11 and the levelness measuring module 12 from the position where the measured distance is 0 mm to the position where the measured distance is 300 mm through the slider 131, during the movement of the straightness measuring module 11 and the levelness measuring module 12, the distance measuring device 20 measures the measured distance and outputs the measured distance data 21 to the error determining module 34, the error determining module 34 calculates the distance error data 341 according to the measured distance data 21 and the measured record point data 311c, the error determining module 34 compares the distance error data 341 with the measured point permission error data 311d, and if the distance error data 341 falls within the range of the measured point permission data 311d, the reminding module 35 gives a reminder, the recording module 33 can automatically receive and record the straightness data 111, the levelness data 121 and the measured distance data 21 outputted by the precision measuring device 10 and the distance measuring device 20.
For example, when the measured distance is 98 mm, the distance measuring device 20 outputs the measured distance data 21 of 98 mm to the error determination module 34, and the error determination module 34 calculates the distance error data 341 of minus 2 mm according to the measured distance data 21(98 mm) and the measured recording point data 311c (for example, 100 mm), since the distance error data 341 (minus 2 mm) is not within the range of the measured point allowable error value data 311d (plus or minus 1 mm), the reminding module 35 will not issue a warning and the recording module 33 will not record the measured data. When the measurement distance is 99 mm, the distance error data 341 calculated by the error determination module 34 is minus 1 mm, since the distance error data 341 (minus 1 mm) is within the range of the measurement point allowable error value data 311d (plus or minus 1 mm), the reminding module 35 flashes a green light on the display module 37 to remind the user that the precision measurement device 10 has reached the measurement record point set by the measurement point data 311c, and the recording module 33 records the measurement data straightness data 111, levelness data 121, and measurement distance data 21.
In addition, in other embodiments of the present invention, the sliding block 131 can make the straightness measuring module 11 and the levelness measuring module 12 automatically move from the position where the measuring distance is 0 mm to the position where the measuring distance is 300 mm, when the distance measuring device 20 measures that the precision measuring device 10 moves to the position where the measured distance has the value of 0 mm, 100 mm, 200 mm and 300 mm, that is, when the precision measuring device 10 moves to the measuring recording points (0 mm, 100 mm, 200 mm and 300 mm) set by the measuring recording point data 311c, the precision measuring device 10 will measure the straightness and levelness of the object 200, the precision measuring device 10 outputs the straightness data 111 and the levelness data 121 simultaneously and the distance measuring device 20 outputs the distance measuring data 21 to the data analysis module 32 simultaneously.
A data analysis step S5: the data analysis module 32 receives and records the straightness data 111, the levelness data 121 and the measurement distance data 21 to analyze and display the geometric accuracy result 321. As shown in table 1, the geometric precision result 321 analyzed by the data analysis module 32 in the embodiment of the present invention is shown.
