[0048] In addition, the machine tool equipment may also include a rotary table, a rotary spindle, a probe and a milling cutter mounted on the rotary spindle, etc.

[0049] Combination Figure 2 This application also provides a method for detecting the vertical-to-horizontal conversion accuracy of a rotary axis applicable to the aforementioned machine tool equipment. The method steps defined in the process flow of the method for detecting the vertical-to-horizontal conversion accuracy of the rotary axis can be implemented by the machine tool equipment. The following will describe... Figure 2 The specific process shown will be explained in detail.

[0050] Step S110: For the first reference point located on the first reference surface of the detection block of the turntable, the probe is used to obtain the coordinate value of the first reference point on the first direction axis when the machine tool is in a horizontal state, to obtain the first coordinate value, and the probe is used to obtain the coordinate value of the first reference point on the first direction axis when the machine tool is in an vertical state, to obtain the second coordinate value.

[0051] In this embodiment, the machine tool can obtain a first coordinate value by using a probe to acquire the coordinate value of the first reference point on the first reference surface of the detection block on the turntable when the machine tool is in a horizontal position, along the first direction axis; and obtain a second coordinate value by acquiring the coordinate value of the first reference point on the first direction axis when the machine tool is in a vertical position. The first reference surface is perpendicular to the first direction axis, such as the z-axis.

[0052] Step S120: For the second reference point located on the second reference surface of the detection block of the turntable, the probe is used to obtain the coordinate value of the second reference point on the second direction axis when the machine tool is in a horizontal state, to obtain a third coordinate value, and the probe is used to obtain the coordinate value of the second reference point on the second direction axis when the machine tool is in an vertical state, to obtain a fourth coordinate value.

[0053] In this embodiment, the machine tool can obtain a third coordinate value by using the probe to acquire the coordinate value of the second reference point on the second direction axis when the machine tool is in a horizontal position, and a fourth coordinate value by acquiring the coordinate value of the second reference point on the second direction axis when the machine tool is in a vertical position. The first direction axis and the second direction axis are different (e.g., perpendicular to each other), and the first reference plane and the second reference plane are different (e.g., perpendicular to each other), with the second reference plane perpendicular to the second direction axis, such as the y-axis.

[0054] Step S130: Based on the first coordinate value and the second coordinate value, determine the vertical-to-horizontal conversion accuracy error of the machine tool equipment on the first direction axis, and based on the third coordinate value and the fourth coordinate value, determine the vertical-to-horizontal conversion accuracy error of the machine tool equipment on the second direction axis.

[0055] In this embodiment of the application, after obtaining the first coordinate value, the second coordinate value, the third coordinate value, and the fourth coordinate value, the machine tool can determine the vertical-to-horizontal conversion accuracy error of the machine tool on the first direction axis based on the first coordinate value and the second coordinate value (e.g., by calculating the difference between the first coordinate value and the second coordinate value), and determine the vertical-to-horizontal conversion accuracy error of the machine tool on the second direction axis based on the third coordinate value and the fourth coordinate value (e.g., by calculating the difference between the third coordinate value and the fourth coordinate value).

[0056] Based on the above, since the detection of vertical-to-horizontal conversion accuracy error can be automatically realized, it is more objective and accurate than the existing technology that requires more manual intervention. Therefore, it can improve the problem of relatively low reliability of vertical-to-horizontal conversion accuracy detection in the existing technology.

[0057] Firstly, regarding step S110, it should be noted that the specific method for detecting the first coordinate value and the second coordinate value is not limited and can be selected according to actual needs.

[0058] For example, in an alternative implementation, to ensure the reliability of the detected first and second coordinate values, step S110 may include the following:

[0059] On one hand, when the machine tool is in a horizontal position, the contact point of the side head is aligned with the first reference point on the first reference surface of the detection block on the turntable, and the coordinate value of the first reference point on the first direction axis is obtained through the contact point of the side head to obtain a first coordinate value; on the other hand, when the machine tool is in a vertical position, the contact point of the side head is aligned with the first reference point on the first reference surface of the detection block on the turntable, and the coordinate value of the first reference point on the first direction axis is obtained through the contact point of the side head to obtain a second coordinate value.

[0060] In other words, a fixed point can be selected on the first reference plane as the first reference point, which serves as the vertical-to-horizontal conversion accuracy detection point on the first direction axis. In this way, the probe can be placed on the rotating axis, and each drive axis can be controlled to return to its original position and be in a horizontal state. The turntable remains at zero position, and the handwheel is operated to align the ruby ​​contact of the probe with the first reference point, keeping the distance h (h≤ the maximum distance of the probe's measurement movement) on the first direction axis. The probe's detection program is then started to complete the reading and storage of the coordinate value Z1 of the first reference point on the first direction axis in the horizontal state.

[0061] Furthermore, the tool center point control command (RTCP function) can be activated, so that the machine tool is in a vertical position, the rotary table remains at zero position, the ruby ​​contact of the probe is aligned with the first reference point, the distance h (h≤ the maximum distance of the probe's measurement movement) is kept on the first direction axis, the probe's detection program is started, and the coordinate value Z2 of the first reference point on the first direction axis in the vertical position is read and stored.

[0062] Based on this, in step S130, the vertical-to-horizontal conversion accuracy error H1=Z1-Z2 on the first direction axis can be calculated, that is, the difference between the first coordinate value and the second coordinate value.

[0063] In addition, it should be noted that, for step S110, in order to further improve the reliability of the detection, step S110 may further include the following:

[0064] After the detection block is installed on the turntable, in a horizontal position, the turntable is controlled to remain at the zero position, and the milling cutter is controlled to mill the first reference surface of the detection block so that the flatness of the first reference surface is within 0.03mm.

[0065] Secondly, regarding step S120, it should be noted that the specific method for detecting the third coordinate value and the fourth coordinate value is not limited and can be selected according to actual needs.

[0066] For example, in an alternative implementation, to ensure the reliability of the detected third and fourth coordinate values, step S120 may include the following:

[0067] On one hand, when the machine tool is in a horizontal position, the contact point of the side head is aligned with the second reference point on the second reference surface of the detection block on the turntable, and the coordinate value of the second reference point on the second direction axis is obtained through the contact point of the side head to obtain a third coordinate value; on the other hand, when the machine tool is in a vertical position, the contact point of the side head is aligned with the second reference point on the second reference surface of the detection block on the turntable, and the coordinate value of the second reference point on the second direction axis is obtained through the contact point of the side head to obtain a fourth coordinate value.

[0068] In other words, a fixed point can be selected on the second reference plane as the second reference point and the vertical-to-horizontal conversion accuracy detection point on the second direction axis. Then, the probe can be placed on the rotating axis, each drive axis returns to its origin position, and the machine tool is controlled to be in a horizontal state. The turntable remains at zero position. The handwheel is operated to align the ruby ​​contact of the probe with the second reference point, keeping the distance h (h≤ the maximum distance of the probe's measurement movement) on the second direction axis. The probe's detection program is started to complete the reading and storage of the coordinate value Y1 of the second reference point on the second direction axis in the horizontal state.

[0069] Furthermore, the five-axis linkage control command can be activated to control the machine tool to be in a vertical position, keep the turntable at zero position, adjust the ruby ​​contact of the probe to align with the second reference point, keep the distance h (h≤ the maximum distance of the probe's measurement movement) on the second direction axis, start the probe's detection program, and complete the reading and storage of the coordinate value Y2 of the second reference point on the second direction axis in the vertical position.

[0070] Based on this, in step S130, the vertical-to-horizontal conversion accuracy error H2=Y1-Y2 on the second direction axis can be calculated, that is, the difference between the third coordinate value and the fourth coordinate value.

[0071] Thirdly, it should also be noted that, in order to further verify the accuracy error obtained based on step S130, the method for detecting the accuracy of rotating shaft vertical-horizontal conversion may also include the following steps, such as steps S140, S150 and S160, the specific contents of each step are as follows.

[0072] Step S140: Based on the vertical-to-horizontal conversion accuracy error of the machine tool on the first direction axis and the vertical-to-horizontal conversion accuracy error on the second direction axis, perform parameter compensation on the machine tool.

[0073] In this embodiment of the application, the machine tool equipment can perform parameter compensation based on the vertical-to-horizontal conversion accuracy error of the machine tool equipment on the first direction axis and the vertical-to-horizontal conversion accuracy error on the second direction axis. The specific compensation process can refer to the relevant prior art, and will not be described in detail here.

[0074] Step S150: After parameter compensation of the machine tool equipment, the test piece located on the turntable is processed, and at least one dimensional parameter of the processed test piece is obtained.

[0075] In this embodiment of the application, the machine tool can process the test piece located on the turntable after parameter compensation, and obtain at least one dimensional parameter of the processed test piece.

[0076] Step S160: Based on the preset configuration of reference dimension parameters and the at least one dimension parameter, determine whether the vertical-to-horizontal conversion accuracy of the machine tool after parameter compensation meets the processing requirements.

[0077] In this embodiment, the machine tool can determine whether its vertical-to-horizontal conversion accuracy after parameter compensation meets the machining requirements based on preset configured reference dimensional parameters and the at least one dimensional parameter. For example, if the difference between the reference dimensional parameter and the dimensional parameter is small (e.g., less than a configured threshold), it can be determined that the machining requirements are met. Conversely, if the difference between the reference dimensional parameter and the dimensional parameter is large (e.g., greater than or equal to a configured threshold), it can be determined that the machining requirements are not met.

[0078] It is understood that the specific method of processing the test piece and obtaining its dimensional parameters in step S150 above is not limited. For example, in an alternative embodiment, step S150 above may further include the following:

[0079] First, after parameter compensation of the machine tool equipment, the rotary table can be controlled to remain at the zero position;

[0080] Secondly, the first and second webs of the test cut piece located on the turntable can be machined in a horizontal position;

[0081] Finally, in a vertical position, the first and second surfaces of the test piece can be machined, and the thickness dimensions of the machined flange, first web, and second web can be obtained to determine at least one dimensional parameter of the machined test piece. The thickness dimension of the machined flange characterizes the vertical-to-horizontal conversion accuracy of the machine tool on the second direction axis, and the thickness dimensions of the machined first and second webs characterize the vertical-to-horizontal conversion accuracy of the machine tool on the first direction axis. Thus, in step S160 above, the thickness dimensions of the machined flange, first web, and second web can be compared with their corresponding theoretical values ​​to determine whether the machining requirements are met.

[0082] Based on the above embodiments, in order to facilitate the understanding of the method for detecting the vertical-horizontal conversion accuracy of the rotary shaft, the following specific embodiments are further provided.

[0083] Taking a certain model of 800x800 vertical-horizontal conversion machining center with a rotary table as an example, the vertical-horizontal conversion accuracy error in the Z-axis direction of its rotary axis is detected, such as... Figure 3 As shown.

[0084] Step 1: Compile the main program L000 and subroutine L001 of the probe detection program. The main program L000 defines the setting of the motion axis and direction, the calling of subroutine L001, and the vertical / horizontal conversion instructions.

[0169] Step 2: Install the test block on the turntable. In the horizontal position, keep the turntable at zero position and use a milling cutter to mill the reference surface C / D to ensure that the flatness of the reference surface C / D is within 0.03mm.

[0170] Step 3: Select a fixed point A on the reference plane C as the vertical-to-horizontal conversion accuracy test point in the Z-axis direction. Place the probe on the spindle (rotary axis), return each drive axis of the machine tool to its origin position, and put the machine tool in a horizontal state. Keep the turntable at zero position. Use the handwheel to align the ruby ​​contact of the probe with point A, maintaining a Z-axis distance of less than 30. Start the probe L000 program until it reaches segment N009, where the M00 program pauses. By calling the L001 subroutine and conditionally determining that the defined motion axis is the Z-axis and the motion direction is negative, the measurement motion trajectory of segments N054-N066 is automatically executed. The coordinate value Z1 of point A in the horizontal state is automatically read and stored in Z_W. The current value Z1 is recorded as -135.3275mm.

[0171] Step 4: Continue to start and execute the L000 program until the M00 program in segment N012 is paused. At this time, the machine tool is in a vertical position, and the rotary table remains at zero position. Continue to start and execute the L000 program. By calling the L001 subroutine and conditionally judging that the defined motion axis is the Z-axis and the motion direction is negative, the measurement motion trajectory of segments N054-N066 is automatically executed. The coordinate value Z2 of point A in the vertical position is automatically read and stored in Z_W. The current value Z2 is recorded as -135.2435mm.

[0172] Step 5: Calculate the Z-axis vertical-to-horizontal conversion accuracy error H1 = -135.3275 - (-135.2435) = -0.084 mm, and compensate the Z-axis vertical-to-horizontal conversion accuracy error of -0.084 mm into the corresponding parameters.

[0173] In addition, taking a certain model of 800x800 vertical-to-horizontal conversion machining center with a rotary table as an example, the vertical-to-horizontal conversion accuracy error in the Y-axis direction of its rotation axis is tested, such as... Figure 4 As shown.

[0174] Step 1: Compile the main program L000 and subroutine L001 of the probe detection program. The main program L000 defines the setting of the motion axis and direction, the calling of subroutine L001, and the vertical / horizontal conversion instructions. The subroutine L001 defines the data type, execution conditions, the storage location of the probe detection result data, the reading of the initial position of the probe to start measurement, the definition of the motion axis and direction, the measurement mode, the probe alarm, and the probe motion trajectory.

[0259] Step 2: Select a fixed point B on the reference plane D as the vertical-to-horizontal conversion accuracy test point in the Y-axis direction. Place the probe on the spindle, return each drive axis of the machine tool to its origin position, and put the machine tool in a horizontal state. Keep the turntable at zero position. Use the handwheel to align the ruby ​​contact of the probe with point B, maintaining a Y-axis distance of less than 30. Start the probe L000 program until it reaches segment N009, where the M00 program pauses. By calling the L001 subroutine and conditionally determining that the defined motion axis is the Y-axis and the motion direction is negative, the measurement motion trajectory of N026-N038 is automatically executed. The coordinate value Y1 of point B in the horizontal state is automatically read and stored in Y_W. The current value Y1 = 186.3768 mm is recorded.

[0260] Step 3: Continue to start and execute the L000 program until the M00 program in segment N012 is paused. At this time, the machine tool is in a vertical position. Continue to start and execute the L000 program. By calling the L001 subroutine and conditionally judging that the defined motion axis is the Y-axis and the motion direction is negative, the measurement motion trajectory of N026-N038 is automatically executed. The coordinate value Y2 of point B in the vertical position is automatically read and stored in Y_W. The current value Y2 = 186.2326mm is recorded.

[0261] Step 4: Calculate the Y-axis vertical-to-horizontal conversion accuracy error H2 = 186.3768 - 186.1926 = 0.1442 mm, and compensate the Y-axis vertical-to-horizontal conversion accuracy error of 0.1442 mm into the corresponding parameters.

[0262] In addition, taking a certain model of 800X800 vertical-to-horizontal conversion machining center with a rotary table as an example, after completing the error compensation for the vertical-to-horizontal conversion accuracy in the Y / Z axes, the vertical-to-horizontal conversion accuracy error of its rotary axis was verified by trial cutting. The machining accuracy error of the trial cut part was ≤±0.1mm, and the theoretical dimensions for verification were: web G=2.0mm, web L=3.0mm, and flange K=2.5mm. Figure 5 As shown.

[0263] Step 1: Place the I side of the test cut piece flat against the turntable, use the J boss to press it down, and level the M side to ensure that the flatness of the M side is ≤0.05mm.

[0264] Step 2: Activate the tool center point control command (RTCP function), keep the rotary table at zero position, install a 20mm diameter milling cutter with a bottom angle of R3 on the spindle, and machine the web plate G and web plate L-shaped cavity in horizontal position.

[0265] Step 3: Activate the tool center point control command (RTCP function). The machine tool, in vertical position, uses the same tool to mill surfaces E and F, forming the flange K, web G, and web L. The dimensional accuracy of web G and web L is obtained from the Z-axis vertical-to-horizontal conversion accuracy control, and the dimensional accuracy of flange K is obtained from the Y-axis vertical-to-horizontal conversion accuracy control.

[0266] Step 4: Use measuring tools to measure the dimensions of the flange K, web G, and web L, obtaining dimensions K1=2.48mm, G1=1.96mm, and L1=2.95mm respectively. By comparing K1, G1, and L1 with the theoretical dimensions, the deviations are 0.02mm, 0.04mm, and 0.05mm respectively. The machining accuracy error of each feature is ≤±0.1mm, the trial cut is qualified, and the vertical-horizontal conversion accuracy of the machine tool meets the machining requirements.

[0267] Combination Figure 6 This application also provides a rotary axis vertical-to-horizontal conversion accuracy testing device applicable to the above-mentioned machine tool equipment. The rotary axis vertical-to-horizontal conversion accuracy testing device may include a first coordinate detection module, a second coordinate detection module, and a conversion accuracy testing module.

[0268] The first coordinate detection module is used to obtain the coordinates of a first reference point on a first reference surface located on the turntable via a probe, specifically, the coordinates of the first reference point on a first direction axis when the machine tool is in a horizontal position, thus obtaining a first coordinate value; and to obtain the coordinates of the first reference point on the first direction axis when the machine tool is in an vertical position, thus obtaining a second coordinate value. The first reference surface is perpendicular to the first direction axis. In this embodiment, the first coordinate detection module can be used to perform... Figure 2 For details regarding step S110 shown, please refer to the previous description of step S110 for information about the first coordinate detection module.

[0269] The second coordinate detection module is used to obtain, via the probe, the coordinate values ​​of the second reference point on the second direction axis when the machine tool is in a horizontal position, to obtain a third coordinate value; and to obtain the coordinate values ​​of the second reference point on the second direction axis when the machine tool is in an vertical position, to obtain a fourth coordinate value. The first direction axis and the second direction axis are different, and the first reference plane and the second reference plane are different, with the second reference plane perpendicular to the second direction axis. In this embodiment, the second coordinate detection module can be used to perform... Figure 2 The relevant content regarding the second coordinate detection module in step S120 shown can be found in the previous description of step S120.

[0270] The conversion accuracy detection module is used to determine the vertical-to-horizontal conversion accuracy error of the machine tool on the first direction axis based on the first coordinate value and the second coordinate value, and to determine the vertical-to-horizontal conversion accuracy error of the machine tool on the second direction axis based on the third coordinate value and the fourth coordinate value. In this embodiment, the conversion accuracy detection module can be used to perform... Figure 2 The relevant content regarding the conversion accuracy detection module in step S130 shown can be found in the previous description of step S130.

[0271] In this embodiment of the application, corresponding to the above-described method for detecting the vertical-to-horizontal conversion accuracy of a rotary axis applied to the machine tool, a computer-readable storage medium is also provided, which stores a computer program that executes the various steps of the method for detecting the vertical-to-horizontal conversion accuracy of a rotary axis when the computer program is run.

[0272] The steps executed by the aforementioned computer program during runtime will not be described in detail here, but can be found in the explanation of the rotary shaft vertical-horizontal conversion accuracy detection method described above.

[0273] In summary, the rotary shaft vertical-horizontal conversion accuracy detection method, apparatus, equipment, and medium provided in this application firstly obtain a first coordinate value by acquiring the coordinates of a first reference point on a first direction axis in a horizontal state, and then obtains a second coordinate value by acquiring the coordinates of the first reference point on the first direction axis in a vertical state. Secondly, it obtains a third coordinate value by acquiring the coordinates of a second reference point on a second direction axis in a horizontal state, and then obtains a fourth coordinate value by acquiring the coordinates of the second reference point on the second direction axis in a vertical state. Then, it determines the vertical-horizontal conversion accuracy error on the first direction axis based on the first and second coordinate values, and determines the vertical-horizontal conversion accuracy error on the second direction axis based on the third and fourth coordinate values. Based on the above, since the vertical-horizontal conversion accuracy error can be automatically detected, it is more objective and accurate than existing methods that require more manual intervention. Therefore, it can improve the problem of relatively low reliability in vertical-horizontal conversion accuracy detection in existing technologies.
