Description

Technical Field

[0002] Laser tool setting instruments are widely used in CNC machine tools to accurately measure the position and size of tools to ensure high precision and efficiency of the machining process. When using, the laser tool setting instrument needs to be installed on the workbench and debugged to the installation standard so that the deviation value of the laser beam meets the required accuracy requirements.

[0003] The installation and debugging of traditional laser tool setting instruments rely on manual operation. First, the technicians manually adjust the position and posture of the tool setting instrument based on previous installation experience; then use calibration tools and dial indicators to accurately measure and adjust the position of the tool setting instrument to ensure its parallelism and verticality; in addition, it is necessary to use steel gaskets of different thicknesses at the bottom of the tool setting instrument, and adjust the height and level of the tool setting instrument by increasing or decreasing the number and thickness of the gaskets. The whole process requires repeated debugging many times, especially inside the machine tool with limited space. The operation is more difficult, time-consuming and has a low pass rate.

[0022] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the drawings of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

The terms "installed", "connected" and "connected" should be understood in a broad sense.

In addition, the meaning of "multiple" is two or more.

[0024] The debugging of laser tool setting instrument is to calibrate the laser beam of laser tool setting instrument to the required absolute deviation of axial deviation and radial deviation relative to the main axis of the machine tool, so as to ensure the processing quality of the product. The traditional debugging method of laser tool setting instrument is to install the laser tool setting instrument on the target machine tool that needs to use the laser tool setting instrument through the tooling base plate, and directly calibrate and debug the axial deviation and radial deviation of the laser beam on the target machine tool.

[0025] Among them, axial deviation refers to the deviation of the laser beam in the axial direction of the machine tool's spindle, which affects the perpendicularity of the laser beam and the spindle; radial deviation refers to the deviation of the laser beam in the radial direction of the machine tool's spindle, which affects the parallelism of the laser beam and a moving axis of the spindle.

[0026] The laser tool setting instrument debugging method provided in an embodiment of the present invention is to first complete the calibration and debugging of the axial deviation of the laser beam on the debugging machine tool, then transfer the assembly formed by the laser tool setting instrument and the tooling base plate after the axial deviation calibration and debugging is completed to the target machine tool, and then complete the calibration and debugging of the radial deviation of the laser beam on the target machine tool.

[0027] Combine the following Figure 1-Figure 4 The laser tool setting instrument debugging method of the present invention is described.

[0028] The laser tool setting instrument debugging method provided by the embodiment of the present invention comprises the following steps: Step S1, install the laser tool setting instrument 1 on the tooling base plate 2, and fix the tooling base plate 2 on the first workbench 31 of the debugging machine tool 3. Figure 1 and Figure 2 .

[0029] Step S2, installing a standard tool on the first spindle of a first head (not shown) of the debugging machine tool 3, and determining the axial deviation of the laser beam 11 of the laser tool setting instrument 1 relative to the first spindle based on the standard tool.

[0030] Step S3, remove the laser tool setting instrument 1 from the tooling base plate 2, and control the debugging machine tool 3 to perform milling processing on the first mounting surface of the tooling base plate 2 according to the axial deviation of the laser beam 11 relative to the first spindle, see Figure 3 The first mounting surface is used for mounting the laser tool setting instrument 1 .

[0031] Step S4, install the laser tool setting instrument 1 back onto the tooling base plate 2, and repeat step S2.

[0032] Step S5, if it is determined that the axial deviation of the laser beam 11 relative to the first main axis is less than or equal to the set axial deviation value, then execute step S6; otherwise, execute step S3.

[0033] Step S6, remove the assembly formed by the laser tool setting instrument 1 and the tooling base plate 2 from the first workbench 31, and fix it to the target machine tool, and adjust the radial deviation of the laser beam 11 relative to the second spindle of the target machine tool so that the radial deviation is less than or equal to the set radial deviation value.

[0034] The standard tool has precise dimensions and known geometric parameters. The tooling base plate 2 is fixed on the surface of the first workbench 31, and step S2 is performed when the surface of the first workbench 31 is in the state of the 0-0 reference plane. Step S2 can be controlled and executed by debugging the calibration program set in the machine tool 3. In step S2, the standard tool is installed on the first spindle of the first machine head, and the movement of the first machine head is controlled so that the laser tool setting instrument 1 performs axial and radial scanning on the standard tool. According to the scanning results, the axial deviation and radial deviation of the laser beam 11 relative to the first spindle can be determined.

[0035] Specifically, a calibration program is provided in the debugging machine tool 3. Based on the calibration program, the debugging machine tool 3 controls the movement of the first machine head, so that the laser tool setting instrument 1 scans the standard tool to obtain the scanning geometric parameters of the standard tool. Based on the calibration program, the debugging machine tool 3 compares the scanning geometric parameters with the known geometric parameters to obtain the axial deviation and radial deviation of the laser beam 11 relative to the first spindle, and outputs the deviation value to the display screen for display.

[0036] The above-mentioned set axial deviation value is the maximum allowable value of the axial deviation of the laser beam 11 of the laser tool setting instrument 1 on the target machine tool relative to its second spindle. The set radial deviation value is the maximum allowable value of the radial deviation of the laser beam 11 of the laser tool setting instrument 1 on the target machine tool relative to its second spindle.

[0037] In step S3, the axial deviation of the laser beam 11 relative to the first spindle is determined in step S2, and the height difference between the two ends of the laser beam 11 with respect to the 0-0 reference plane can be determined according to the axial deviation. Since the positions of the laser tool setting instrument 1 and the tooling base plate 2 are fixed, the height difference can be reduced by controlling the debugging machine tool 3 to perform milling on the mounting surface of the tooling base plate 2 according to the height difference, thereby realizing the calibration of the axial deviation.

[0038] After completing step S3, the axial deviation of the laser beam 11 relative to the first spindle is tested through step S4, that is, the laser tool setting instrument 1 is reinstalled to scan the standard tool again, and the axial deviation of the laser beam 11 relative to the first spindle is re-determined. If it is determined in step S5 that the axial deviation obtained by the test is less than or equal to the set axial deviation value, it indicates that the axial deviation has been calibrated to the set standard, and the next step S6 is continued; otherwise, step S3 is repeated, and the mounting surface of the tooling base plate 2 is milled again according to the axial deviation re-determined in step S4, until the axial deviation determined in step S4 is less than or equal to the set axial deviation value, and the axial deviation is calibrated to the set standard.

[0039] Since the mounting surface for installing the laser tool setter 1 on the target machine tool is a 0-0 reference surface, after the axial deviation of the laser beam 11 of the laser tool setter 1 relative to the first spindle is adjusted to below the set axial deviation value by the debugging method of the embodiment of the present invention, the integral assembly formed by the laser tool setter 1 and the tooling base plate 2 is installed on the mounting surface of the target machine tool, which can ensure that the axial deviation of the laser tool setter 1 relative to the second spindle of the target machine tool meets the requirements, without the need to calibrate the axial deviation by adding or removing shims. Then, the radial deviation of the laser beam 11 of the laser tool setter 1 relative to the second spindle is adjusted on the target machine tool so that the radial deviation is less than or equal to the set radial deviation value, and the entire debugging process is completed.

[0040] The laser tool setting instrument debugging method provided in an embodiment of the present invention is to install the laser tool setting instrument 1 to be debugged on the first workbench 31 of the debugging machine tool 3, determine the axial deviation of the laser beam 11 of the laser tool setting instrument 1 relative to the first spindle of the debugging machine tool 3 based on the standard tool on the debugging machine tool 3, and control the debugging machine tool 3 to perform milling processing on the installation surface of the tooling base plate 2 according to the axial deviation. That is, the axial deviation of the laser tool setter 1 is calibrated on the debugging machine tool 3 in advance by means of milling compensation. When the target machine tool is installed on site, the assembly formed by fixing the laser tool setter 1 and the tooling base plate 2 is installed on the target machine tool. There is no need to calibrate the axial deviation by adding or removing gaskets, which improves the installation accuracy and stability of the laser tool setter, improves the qualified rate of debugging, and is beneficial to improving production efficiency and processing quality. In addition, it is only necessary to calibrate the radial deviation of the laser beam 11, that is, it is only necessary to perform calibration and debugging in one radial dimension, which reduces the operating space requirement on the target machine tool, is suitable for machine tools with limited space, simplifies the debugging operation, greatly shortens the installation and debugging time of the laser tool setter 1, and is beneficial to improving production efficiency.

[0041] It should be noted that when the first workbench 31 is at the 0-0 reference plane, the X-axis, Y-axis and Z-axis of the first workbench 31 and the three moving axes of the first head are in the same coordinate system, see Figure 2 .

[0042] In the embodiment of the present invention, Figure 1 and Figure 2 As shown, the first workbench 31 can rotate around the A axis, and the A axis is the rotation axis around the X axis of the first workbench 31. The direction of the laser beam 11 and the length direction of the tooling base plate 2 are consistent with the Y axis direction of the first workbench 31. After step S2 and before step S3, it also includes: Step S21, determining a first rotation angle according to an axial deviation of the laser beam 11 relative to the first main axis and a set axial deviation value; and controlling the first workbench 31 to swing around the A axis at the first rotation angle.

[0043] Among them, since the direction of the laser beam 11 and the length direction of the tooling base plate 2 are consistent with the Y-axis direction of the first workbench 31, the axial deviation of the laser beam 11 represents the height difference between the two ends of the laser beam 11. In the embodiment of the present invention, the thickness difference between the two ends of the tooling base plate 2 in the length direction is adjusted by milling the tooling base plate 2 to reduce the height difference between the two ends of the laser beam and realize the calibration of the axial deviation.

[0044] Specifically, according to the axial deviation determined in step S2, the actual height difference between the two ends of the laser beam 11 relative to the 0-0 reference plane is determined; according to the set axial deviation value, the target height difference between the two ends of the laser beam 11 relative to the 0-0 reference plane to be obtained by swinging the first angle of the first worktable 31 around the A axis is determined. Then, the first angle is determined according to the difference between the actual height difference and the target height difference, and the first worktable 31 is controlled to swing the first angle around the A axis. The first angle should be targeted to have an axial deviation less than or equal to the set axial deviation value. After the first worktable 31 rotates around the A axis by the first angle, the current posture of the first worktable 31 is maintained, and the first head is controlled to perform milling processing on the upper surface of the tooling base plate 2 on the 0-0 reference plane, so as to achieve the calibration of the axial deviation of the laser beam 11.

[0045] To ensure that the axial deviation of the laser beam 11 relative to the first spindle after step S21 is less than or equal to the set axial deviation value, and that the axial deviation of the laser beam 11 relative to the second spindle of the target machine tool is less than or equal to the set axial deviation value when the laser tool setting instrument 1 is installed on the target machine tool after step S3, in the embodiment of the present invention, after step S21 and before step S3, the following is further included: Step S22, execute step S2.

[0046] Step S23, if it is determined that the axial deviation of the laser beam 11 relative to the first main axis is less than or equal to the first set value, then execute step S3; otherwise, execute steps S21 to S22; the first set value is less than or equal to the set axial deviation value.

[0047] Specifically, after the first workbench 31 rotates around the A axis by the first angle, step S2 is repeated to test the axial deviation, that is, the standard tool is scanned again by the laser tool setting instrument 1 to re-determine the axial deviation of the laser beam 11 relative to the first spindle. If the re-determined axial deviation is less than or equal to the first set value, the next milling process is performed; otherwise, steps S21 and 22 are repeated until the latest determined axial deviation is less than or equal to the first set value.

[0048] Among them, the first set value is less than the set axial deviation, that is, the goal of rotating and adjusting the first worktable 31 around the A-axis in step S21 is to achieve a higher accuracy standard than that required by the target machine tool, so as to ensure that when the laser tool setting instrument 1 is installed on the target machine tool after step S3, the axial accuracy of the laser beam 11 meets the accuracy requirements.

[0049] In the embodiment of the present invention, Figure 1 and Figure 2 As shown, the first workbench 31 can rotate around the C-axis, and the C-axis is a rotation axis around the Z-axis of the first workbench 31 .

[0050] Step S2 further includes: determining a radial deviation of the laser beam 11 relative to the first spindle based on a standard tool.

[0051] Step S21 also includes: determining a second rotation angle according to a radial deviation of the laser beam 11 relative to the first main axis and a set radial deviation value; and controlling the first workbench 31 to rotate around the C axis by the second rotation angle.

[0052] Among them, although the direction of the laser beam 11 and the length direction of the tooling base plate 2 are consistent with the Y-axis direction of the first workbench 31, due to the assembly error between the tooling base plate 2 and the laser tool setting instrument 1 and the assembly error between the tooling base plate 2 and the first workbench 31, the laser beam 11 still has a large radial deviation relative to the first spindle. In the embodiment of the present invention, the radial deviation determined in step S2 is calibrated by rotating the first workbench 31 around the C-axis, which is conducive to improving the calibration accuracy of the axial deviation in the subsequent steps.

[0053] Specifically, according to the radial deviation determined in step S2, the actual deflection angle of the laser beam 11 relative to a moving axis of the first main axis is determined; according to the set radial deviation value, the target deflection angle of the laser beam 11 relative to the moving axis to be obtained by rotating the first worktable 31 around the C axis by a second angle is determined. Then, the second angle is determined according to the difference between the actual deflection angle and the target deflection angle, and the first worktable 31 is controlled to rotate around the C axis by the second angle. The second angle should be targeted to have a radial deviation less than or equal to the set radial deviation value. After the first worktable 31 rotates around the A axis by the first angle and around the C axis by the second angle, the current posture of the first worktable 31 is maintained, and the first head is controlled to perform milling processing on the upper surface of the tooling base plate 2 on the 0-0 reference plane, so as to achieve precise calibration of the axial deviation of the laser beam 11.

[0054] In the embodiment of the present invention, step S21 to step S22 can control the precise rotation and swinging functions of the first workbench 31 by debugging the numerical control system of the machine tool 3, ensuring that the position and posture of the laser tool setting instrument meet the high-precision requirements, and correcting it in combination with the milling tool base plate 2, thereby realizing the precise calibration of the axial deviation of the laser tool setting instrument 1. During on-site installation, only simple fine-tuning is required, which greatly shortens the installation time. It also reduces the space requirements for on-site operations, which is particularly suitable for limited machine tool interiors. On-site installation is easy to operate, without the need for complex tools and highly skilled operators.

[0055] In the embodiment of the present invention, after step S1 and before step S2, the following steps are further included: Step S11, install the first scale on the first machine head, control the first machine head to drive the first scale to reciprocate along the first movable axis of the first spindle, and perform a pull-scale detection on the first parallelism of the tooling base plate 2 relative to the first movable axis; control the first workbench 31 to rotate around the C-axis according to the reading of the first scale until the reading range of the first scale is less than or equal to the second set value.

[0056] Specifically, the tooling base plate 2 is a rectangular plate-like member with a certain thickness, and the first gauge can be a dial gauge or a micrometer. The needle of the first gauge is placed against the side surface 21 of a long side of the tooling base plate 2. The first movable axis is a movable axis closest to the length direction of the tooling base plate 2. When the side surface 21 of the tooling base plate 2 is not parallel to the first movable axis, the reading of the first gauge will jump during the process in which the first head drives the first gauge to move back and forth along the direction of the first movable axis.

[0057] The operator can control the first workbench 31 to rotate around the C axis by shaking the hand wheel according to the amplitude of the first scale reading, and observe the change of the first scale reading at the same time. When the reading change range is less than or equal to the second set value, it indicates that the first parallelism of the tooling base plate 2 relative to the first movable axis meets the requirement. For example, the second set value is 0mm-0.002mm.

[0058] When the laser tool setting instrument 1 is assembled with the tool base plate 2, the length direction of the laser tool setting instrument 1 is consistent with the length direction of the tool base plate 2, that is, the direction of the laser beam 11 of the laser tool setting instrument 1 is consistent with the length direction of the tool base plate 2. In this embodiment, by debugging the first head of the machine tool 3 to perform a pull-table test on the side surface 21 of the tool base plate 2, the radial deviation of the laser beam 11 relative to the first spindle can be reduced, which is conducive to improving the calibration accuracy of the axial deviation in the subsequent steps.

[0059] Furthermore, after step S11 and before step S2, the method further includes: Step S12, control the first head to drive the first scale to reciprocate along the first movable axis of the first spindle, and perform a pull-scale detection on the second parallelism of the laser tool setting instrument 1 relative to the first movable axis; tap the side of the laser tool setting instrument 1 according to the reading of the first scale until the reading range of the first scale is less than or equal to the third set value.

[0060] Specifically, the needle of the first gauge is placed against the side surface of the laser tool setting instrument 1 on one side in the length direction. On the basis of completing step S11, if the side of the laser tool setting instrument 1 is not parallel to the side 21 of the tool base plate 2, the reading of the first gauge will jump during the process in which the first head drives the first gauge to move back and forth along the direction of the first moving axis of the first spindle. The parallelism of the side of the laser tool setting instrument 1 relative to the side 21 of the tool base plate 2 will affect the radial deviation of the laser beam 11 relative to the first spindle.

[0061] The operator can adjust the second parallelism of the side of the laser tool setting instrument 1 relative to the first moving axis by tapping the side of the laser tool setting instrument 1 according to the amplitude of the first scale reading, that is, adjust the radial deviation of the laser beam 11 relative to the first moving axis, and observe the change of the first scale reading at the same time. When the reading change range is less than or equal to the third set value, it indicates that the second parallelism of the laser tool setting instrument 1 relative to the first moving axis meets the requirements.

[0062] In particular, since the radial deviation is adjusted by rotating the first workbench 31 around the C-axis in step S21, the third set value can be amplified relative to the set radial deviation value. For example, the third set value is 0.01 mm.

[0063] In this embodiment, the first parallelism of the side surface 21 of the tooling base plate 2 relative to the first movable axis of the first spindle is detected by the debugging machine tool 3, and the first parallelism is calibrated by rotating the first workbench 31 around the C axis; then, the second parallelism of the side surface of the laser tool setter 1 relative to the first movable axis is detected by the debugging machine tool 3, and the second parallelism is calibrated by tapping the laser tool setter 1 to adjust the posture of the laser tool setter 1 on the tooling base plate 2, which can greatly reduce the radial deviation of the laser beam 11 relative to the first spindle, which is beneficial to improve the calibration accuracy of the axial deviation in the subsequent steps.

[0064] It should be noted that the radial deviation can be calibrated by setting the first parallelism and the second parallelism of higher precision standards through steps S11 and S12, and then the radial deviation is tested through step S2. In actual debugging, the radial deviation is also tested in step S22, and then the radial deviation is accurately calibrated by controlling the first workbench 31 to rotate around the C axis in step S21. Therefore, steps S11 and S12 can be used as pre-adjustment steps before executing step S2 to avoid executing step S2 to trigger the alarm program of the debugging machine tool 3 when the radial deviation is too large.

[0065] In the embodiment of the present invention, before step S1, the following steps are further included: Step S101, finely process a rectangular plate-like member with a regular structure, or use an existing rectangular plate-like member that meets the precision requirements. Figure 4 As shown, the rectangular plate-shaped member has a first mounting surface and a second mounting surface facing each other. The first mounting surface is used to mount the laser tool setting instrument 1, and the second mounting surface is used to be mounted and fixed to the table surface of the first workbench 31. The rectangular plate-shaped member is made of a high-rigidity material.

[0066] Step S102 , processing a plurality of bosses 22 on the first mounting surface, wherein the plurality of bosses 22 are arranged at intervals in the length direction of the rectangular plate-like member.

[0067] Step S103 , machining a mounting hole 23 on the boss 22 corresponding to the threaded hole on the laser tool setting instrument 1 .

[0068] In step S102, a plurality of bosses 22 are formed on the first mounting surface by milling a portion of the first mounting surface, and the plurality of bosses 22 are arranged at intervals along the length direction of the tooling base plate 2. The laser tool setting instrument 1 is fixedly mounted on at least two of the bosses 22. In the above step S3, the axial deviation of the laser beam 11 can be calibrated by milling the plurality of bosses 22 of the boss structure.

[0069] Specifically, the plurality of bosses 22 form at least one group of boss structures, each group of boss structures includes at least two bosses 22, and the spacing between the plurality of bosses 22 of different boss structures is different, so that different boss structures are used to install laser tool setting instruments of different specifications and models. The tooling base plate 2 can be used to assemble with laser tool setting instruments 1 of different specifications and models, has flexibility and adjustability, and can adapt to machine tools of different models.

[0070] For example, two bosses 22 are processed on the first mounting surface to form a group of boss structures. For another example, four bosses 22 are processed on the first mounting surface to form a first boss structure and a second boss structure. The first boss structure and the second boss structure each include two bosses 22. The two bosses 22 of the first boss structure are respectively arranged at both ends of the first mounting surface, and the two bosses 22 of the second boss structure are respectively arranged on both sides of the first mounting surface and between the two bosses 22 of the first boss structure. The first boss structure and the second boss structure can be used to install laser tool setting instruments 1 of different sizes.

[0071] In the embodiment of the present invention, the tool base plate 2 is provided with a plurality of mounting holes 23, and the laser tool setting instrument 1 is provided with a plurality of through holes, and the plurality of through holes are arranged in a one-to-one correspondence with the plurality of mounting holes 23. The laser tool setting instrument 1 and the tool base plate 2 are connected by bolts penetrating the mounting holes 23 and the through holes, and the outer diameter of the bolts is smaller than the inner diameter of the mounting holes 23.

[0072] The mounting hole 23 is a through hole that passes through the first mounting surface and the second mounting surface. Specifically, the mounting hole 23 is a countersunk through hole provided on the second mounting surface. In step S1, the laser tool setting instrument 1 is fixed to the tooling base plate 2 by multiple bolts and nuts, but the nuts are not tightened. So that in step S12, the second parallelism can be calibrated by tapping the side of the laser tool setting instrument 1. After completing step S12, tighten the nuts to prevent the laser tool setting instrument 1 and the tooling base plate 2 from moving relative to each other.

[0073] In other embodiments, the mounting hole 23 is a threaded hole, which can be a through hole that passes through the first mounting surface and the second mounting surface, or a blind hole provided on the first mounting surface. The laser tool setting instrument 1 and the tooling base plate 2 are connected by screws that penetrate the mounting hole 23 and the through hole. The screws are successively penetrated through the through hole of the laser tool setting instrument 1 and the mounting hole 23 of the tooling base plate 2 and are threadedly connected to the tooling base plate 2. In this way, the positioning accuracy of the laser tool setting instrument 1 and the tooling base plate 2 can be improved, the readjustment amount is small, micro-adjustment can be achieved, and no nut is required, which saves costs.

[0074] In the embodiment of the present invention, step S6 specifically includes: Step S61 : installing a standard tool on the second spindle, and determining a radial deviation of the laser beam 11 relative to the second spindle based on the standard tool.

[0075] Step S62, adjusting the third parallelism of the second movable axis of the tooling base plate 2 relative to the second main axis according to the radial deviation of the laser beam 11 relative to the second main axis.

[0076] Step S63, executing step S61; Step S64, if it is determined that the radial deviation of the laser beam 11 relative to the second main axis is greater than the set radial deviation value, then step S62 is executed until it is determined that the radial deviation of the laser beam 11 relative to the second main axis is less than or equal to the set radial deviation value.

[0077] The laser tool setting instrument 1 and the tooling base plate 2 that have completed axial calibration are fixed to the table of the second workbench of the target machine tool. The table of the second workbench is in the state of the 0-0 reference plane, and step S61 is executed to detect the radial deviation. Step S61 can be controlled and executed by the calibration program set in the target machine tool.

[0078] In step S61, the standard tool is installed on the second spindle of the second mechanism, and the second mechanism is controlled to move so that the laser tool setting instrument 1 performs axial and radial scanning on the standard tool. The axial deviation and radial deviation of the laser beam 11 relative to the second spindle can be determined according to the scanning structure. Usually, after the steps S1 to S5 of the embodiment of the present invention, the axial deviation of the laser beam 11 relative to the second spindle determined at this time meets the axial accuracy requirement of the target machine tool, and only the radial deviation needs to be calibrated. Specifically, in step S62, the radial deviation is calibrated by adjusting the third parallelism of the second movable axis of the tooling base plate 2 relative to the second spindle.

[0079] After step S62, step S63 is executed, that is, the radial deviation is detected again through step S61 to re-determine the radial deviation of the laser beam 11 relative to the second main axis. If it is determined in step S64 that the radial deviation detected is less than or equal to the set radial deviation value, it indicates that the radial deviation has been calibrated to the set standard. If it is determined in step S64 that the radial deviation detected is greater than the set radial deviation, steps S62 to S63 are repeated until the radial deviation determined in step S63 is less than or equal to the set radial deviation value.

[0080] Specifically, before step S61 , the method further includes: installing a second gauge on a second head of the target machine tool, and placing a measuring end of the second gauge against the side surface 21 of the tooling base plate 2 .

[0081] Step S62 specifically includes: controlling the second head and the second worktable of the target machine tool to move back and forth relative to each other in the direction of the second moving axis, and performing a pull-meter test on the third parallelism. According to the reading of the second gauge, the side surface 21 of the tooling base plate 2 is struck until the reading range of the second gauge reaches the set interval.

[0082] The second moving axis of the second machine head is a moving axis that is closest to the length direction of the tooling base plate 2 and is specifically set according to the model of the target machine tool.

[0083] Since there is also an axial deviation between the laser tool setting instrument 1 and the tooling base plate 2, the axial deviation can be calculated based on the first parallelism and the second parallelism. Therefore, the setting of the set interval takes into account the axial deviation between the laser tool setting instrument 1 and the tooling base plate 2. The set interval can be calculated based on the axial deviation and the set radial deviation value. When the third parallelism reaches the set interval, it indicates that the radial deviation of the laser beam 11 relative to the second spindle reaches the set standard.

[0084] Usually, after the axial deviation calibration of the laser tool setting instrument 1 is completed through the above steps S1 to S5 of the embodiment of the present invention, it can meet the set axial deviation value required by the target machine tool by directly installing it and the tooling base plate 2 on the target machine tool. In actual production, after the laser tool setting instrument 1 and the tooling base plate 2 are installed as a whole on the target machine tool, another test will be performed to ensure that the axial deviation of the laser beam 11 relative to the second spindle of the target machine tool meets the requirements.

[0085] In this regard, in the embodiment of the present invention, step S61 further includes: determining the axial deviation of the laser beam 11 relative to the second spindle based on the standard tool. After step S61 and before step S62, it also includes: determining that the axial deviation of the laser beam 11 relative to the second spindle is greater than the set axial deviation value; then executing steps S1 to S61 until it is determined that the axial deviation of the laser beam 11 relative to the second spindle is less than or equal to the set axial deviation value.

[0086] When the axial deviation of the laser beam 11 relative to the second spindle determined in step S61 does not meet the axial accuracy requirement of the target machine tool, it is necessary to return to the debugging machine tool 3 to recalibrate the axial deviation. After recalibration, return to the target machine tool and perform a test of the axial deviation through step S61, and continue to perform steps S62 to S64 until the test is qualified.

[0087] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present invention.
