Abstract
Description
Technical Field
[0001] This invention relates to the field of laser tool setting technology, and more particularly to a method for adjusting a laser tool setting device. Background Technology
[0002] Laser tool setters are widely used in CNC machine tools to accurately measure the position and dimensions of cutting tools, ensuring high precision and efficiency in the machining process. When using a laser tool setter, it needs to be mounted on the worktable and adjusted to the installation standard so that the deviation value of the laser beam meets the required accuracy.
[0003] Traditional laser tool setters rely on manual operation for installation and debugging. First, technicians manually adjust the tool setter's position and orientation based on past experience. Then, calibration tools and dial indicators are used to precisely measure and adjust the tool setter's position, ensuring its parallelism and perpendicularity. Additionally, steel shims of varying thicknesses are used at the bottom of the tool setter; adjusting the number and thickness of these shims adjusts the tool setter's height and level. This entire process requires repeated adjustments, especially inside machine tools with limited space, making operation more difficult, time-consuming, and resulting in a low pass rate. Adjusting height and level by adding or removing shims leads to low and unstable accuracy, severely impacting production efficiency and processing quality. Summary of the Invention

This method is suitable for machine tools with limited space, simplifies the debugging operation, and greatly shortens the installation and debugging time of the laser tool setter 1, thus improving production efficiency.

[0042] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this invention. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.

The terms "installed," "connected," and "linked" should be interpreted broadly; for example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in the embodiments of the present invention according to the specific circumstances. Furthermore, "multiple" means two or more.
[0044] The debugging of a laser tool setter involves calibrating its laser beam to ensure that the axial and radial deviations relative to the machine tool spindle are below the required absolute values, thus guaranteeing product processing quality. The traditional method involves mounting the laser tool setter onto the target machine tool using a fixture base plate and directly calibrating the axial and radial deviations of the laser beam on the target machine tool.
[0045] Axial deviation refers to the deviation of the laser beam along the spindle axis of the machine tool, which affects the perpendicularity of the laser beam to the spindle; radial deviation refers to the deviation of the laser beam along the spindle radially, which affects the parallelism of the laser beam to one of the moving axes of the spindle.
[0046] The laser tool setter debugging method provided in this embodiment of the invention first completes the calibration and debugging of the axial deviation of the laser beam on the debugging machine tool, then transfers the assembly formed by the laser tool setter and the tooling base plate after the axial deviation calibration and debugging is completed to the target machine tool, and then completes the calibration and debugging of the radial deviation of the laser beam on the target machine tool.
[0047] The following is combined with Figures 1-4 The laser tool setter debugging method of the present invention is described.
[0048] The laser tool setter debugging method provided in this embodiment of the invention includes the following steps:
[0049] Step S1: Install the laser tool setter 1 on the fixture base plate 2, and fix the fixture base plate 2 on the first worktable 31 of the debugging machine tool 3. (See also...) Figure 1 and Figure 2 .
[0050] Step S2: Install the standard tool onto the first spindle of the first head of the debugging machine tool 3 (not shown in the figure), and determine the axial deviation of the laser beam 11 of the laser tool setter 1 relative to the first spindle based on the standard tool.
[0051] Step S3: Remove the laser tool setter 1 from the fixture base plate 2. Based on the axial deviation of the laser beam 11 relative to the first spindle, control the debugging machine tool 3 to perform milling on the first mounting surface of the fixture base plate 2. (See below) Figure 3 The first mounting surface is used to mount the laser tool setter 1.
[0052] Step S4: Reinstall the laser tool setter 1 back onto the tooling base plate 2, and repeat step S2.
[0053] Step S5: If the axial deviation of the laser beam 11 relative to the first spindle is less than or equal to the set axial deviation value, then proceed to step S6; otherwise, proceed to step S3.
[0054] Step S6: Remove the assembly consisting of the laser tool setter 1 and the tooling base plate 2 from the first worktable 31 and fix it to the target machine tool. 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.
[0055] The standard cutting tool has precise dimensions and known geometric parameters. The tooling base plate 2 is fixed to the surface of the first worktable 31. Step S2 is executed when the surface of the first worktable 31 is in a 0-0 reference plane state. Step S2 can be controlled by the calibration program set within the machine tool 3. In step S2, the standard cutting tool is installed on the first spindle of the first machine head. The movement of the first machine head is controlled, causing the laser tool setter 1 to scan the standard cutting tool axially and radially. Based on the scanning results, the axial and radial deviations of the laser beam 11 relative to the first spindle can be determined.
[0056] Specifically, the debugging machine tool 3 is equipped with a calibration program. Based on this calibration program, the debugging machine tool 3 controls the movement of the first head, causing the laser tool setter 1 to scan the standard tool and 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 known geometric parameters to obtain the axial and radial deviations of the laser beam 11 relative to the first spindle, and outputs the deviation values to the display screen.
[0057] The aforementioned axial deviation value is the maximum permissible axial deviation of the laser beam 11 of the laser tool setter 1 on the target machine tool relative to its second spindle. The radial deviation value is the maximum permissible radial deviation of the laser beam 11 of the laser tool setter 1 on the target machine tool relative to its second spindle.
[0058] 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 about the 0-0 reference plane can be determined based on this axial deviation. Since the laser tool setter 1 and the fixture base plate 2 are fixed in position, the height difference can be reduced by controlling the debugging machine tool 3 to mill the mounting surface of the fixture base plate 2, thereby achieving calibration of the axial deviation.
[0059] After completing step S3, step S4 is used to test the axial deviation of the laser beam 11 relative to the first spindle. This involves reinstalling the laser tool setter 1 and scanning the standard tool again to re-determine the axial deviation of the laser beam 11 relative to the first spindle. If, in step S5, the measured axial deviation 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 executed. Otherwise, step S3 is repeated, and the mounting surface of the tooling base plate 2 is milled again based on the re-determined axial deviation in step S4, until the axial deviation determined in step S4 is less than or equal to the set axial deviation value. In this case, the axial deviation has been calibrated to the set standard.
[0060] Since the mounting surface of the laser tool setter 1 on the target machine tool is a 0-0 reference surface, after adjusting the axial deviation of the laser beam 11 of the laser tool setter 1 relative to the first spindle to below the set axial deviation value using the debugging method of this embodiment, the integral assembly consisting of the laser tool setter 1 and the tooling base plate 2 is installed on the mounting surface of the target machine tool. This ensures that the axial deviation of the laser tool setter 1 relative to the second spindle of the target machine tool meets the requirements, without needing 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 to make the radial deviation less than or equal to the set radial deviation value, thus completing the entire debugging process.
[0061] The laser tool setter debugging method provided in this embodiment of the invention involves installing the laser tool setter 1 to be debugged on the first worktable 31 of the debugging machine tool 3, determining the axial deviation of the laser beam 11 of the laser tool setter 1 relative to the first spindle of the debugging machine tool 3 based on a standard tool, and controlling the debugging machine tool 3 to perform milling on the mounting surface of the tooling base plate 2 according to the axial deviation. The axial deviation of the laser tool setter 1 was pre-calibrated on the debugging machine tool 3 through milling compensation. During on-site installation on the target machine tool, the assembly consisting of the laser tool setter 1 and the tooling base plate 2 was installed on the target machine tool. There was no need to calibrate the axial deviation by adding or removing shims, which improved the installation accuracy and stability of the laser tool setter, increased the pass rate of debugging, and helped to improve production efficiency and processing quality. Furthermore, only the radial deviation of the laser beam 11 needed to be calibrated, that is, only calibration and debugging were required in one radial dimension, which reduced the operating space requirement on the target machine tool. This is suitable for machine tools with limited space, simplifies the debugging operation, and greatly shortens the installation and debugging time of the laser tool setter 1, which helps to improve production efficiency.
[0062] It should be noted that when the first worktable 31 is on the 0-0 datum plane, the X, Y, and Z axes of the first worktable 31 are in the same coordinate system as the three moving axes of the first machine head. (See [reference]). Figure 2 .
[0063] In embodiments of the present invention, such as Figure 1 and Figure 2 As shown, the first worktable 31 can rotate about axis A, which is the rotation axis about the X-axis of the first worktable 31. The direction of the laser beam 11 and the length direction of the fixture base plate 2 are consistent with the Y-axis direction of the first worktable 31. After step S2 and before step S3, the following is also included:
[0064] Step S21: Determine the first rotation angle based on the axial deviation of the laser beam 11 relative to the first spindle and the set axial deviation value; control the first worktable 31 to swing around the A-axis by the first rotation angle.
[0065] Since the direction of the laser beam 11 and the length direction of the fixture base plate 2 are consistent with the Y-axis direction of the first worktable 31, the axial deviation of the laser beam 11 indicates a height difference between its two ends. This embodiment of the invention adjusts the thickness difference between the two ends of the fixture base plate 2 along its length direction by milling, thereby reducing the height difference between the two ends of the laser beam and calibrating the axial deviation.
[0066] Specifically, based on 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; based on 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 worktable 31 around the A-axis at a first rotation angle, is determined. Then, the first rotation angle is determined based on the difference between the actual height difference and the target height difference, and the first worktable 31 is controlled to swing around the A-axis at this first rotation angle. This first rotation angle should aim 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 at this first rotation angle, the current posture of the first worktable 31 is maintained, and the first head is controlled to perform milling machining on the upper surface of the tooling base plate 2 on the 0-0 reference plane, thereby achieving the calibration of the axial deviation of the laser beam 11.
[0067] To ensure that the axial deviation of the laser beam 11 relative to the first spindle is less than or equal to a set axial deviation value after step S21, 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 a set axial deviation value when the laser tool setter 1 is installed on the target machine tool after step S3, this embodiment of the invention further includes the following steps after step S21 and before step S3:
[0068] Step S22: Execute step S2. If it is determined that the axial deviation of the laser beam relative to the first spindle is less than or equal to a first set value, then execute step S3; otherwise, execute step S21. The first set value is less than or equal to a set axial deviation value.
[0069] Specifically, after the first worktable 31 rotates by a first angle around axis A, step S2 is repeated to test the axial deviation, that is, the standard tool is scanned again by the laser tool setter 1 to redetermine the axial deviation of the laser beam 11 relative to the first spindle. If the redetermined axial deviation is less than or equal to the first set value, the next milling process is performed; otherwise, after executing step S21, step 2 is executed again. Step S22 is executed until the newly determined axial deviation is less than or equal to the first set value.
[0070] Wherein, the first set value is less than the set axial deviation, that is, the goal of the first worktable 31 rotating and adjusting around the A-axis in step S21 is to achieve a higher precision standard than that required by the target machine tool, so as to ensure that when the laser tool setter 1 is installed on the target machine tool after step S3, the axial accuracy of the laser beam 11 meets the precision requirements.
[0071] In embodiments of the present invention, such as Figure 1 and Figure 2 As shown, the first worktable 31 can rotate around the C-axis, which is the rotation axis around the Z-axis of the first worktable 31.
[0072] Step S2 also includes: determining the radial deviation of the laser beam 11 relative to the first spindle based on a standard tool.
[0073] Step S21 further includes: determining the second rotation angle based on the radial deviation of the laser beam 11 relative to the first spindle and the set radial deviation value; and controlling the first worktable 31 to rotate around the C-axis by the second rotation angle.
[0074] Although the direction of the laser beam 11 and the length direction of the fixture base plate 2 are consistent with the Y-axis direction of the first worktable 31, the assembly errors between the fixture base plate 2 and the laser tool setter 1, as well as between the fixture base plate 2 and the first worktable 31, result in a significant radial deviation of the laser beam 11 relative to the first spindle. In this embodiment of the invention, the radial deviation determined in step S2 is calibrated by rotating the first worktable 31 around the C-axis, which helps improve the calibration accuracy of the axial deviation in subsequent steps.
[0075] Specifically, based on the radial deviation determined in step S2, the actual deflection angle of the laser beam 11 relative to a moving axis of the first spindle is determined; based on the set radial deviation value, the target deflection angle of the laser beam 11 relative to that moving axis, obtained by rotating the first worktable 31 around the C-axis by a second angle, is determined. Then, the second angle is determined based on 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 this second angle. This second angle should aim for a radial deviation less than or equal to the set radial deviation value. After the first worktable 31 rotates around the A-axis by a first angle and around the C-axis by this second angle, the current posture of the first worktable 31 is maintained, and the first head is controlled to perform milling on the upper surface of the tooling base plate 2 on the 0-0 reference plane, which can achieve precise calibration of the axial deviation of the laser beam 11.
[0076] In this embodiment of the invention, steps S21 to S22 can control the precise rotation and oscillation function of the first worktable 31 through the CNC system of the machine tool 3, ensuring that the position and posture of the laser tool setter meet high precision requirements. Combined with correction using the milling fixture base plate 2, precise calibration of the axial deviation of the laser tool setter 1 is achieved. During on-site installation, only simple fine-tuning is required, greatly shortening the installation time. It also reduces the space requirements for on-site operation, making it particularly suitable for machine tool interiors with limited space. On-site installation is simple, requiring no complex tools or highly skilled operators.
[0077] In this embodiment of the invention, after step S1 and before step S2, the method further includes:
[0078] Step S11: Install the first gauge on the first machine head, control the first machine head to drive the first gauge to move back and forth along the first moving axis of the first main shaft, and perform gauge pull test on the first parallelism of the tooling base plate 2 relative to the first moving axis; control the first worktable 31 to rotate around the C-axis according to the reading of the first gauge until the reading of the first gauge is less than or equal to the second set value.
[0079] Specifically, the tooling base plate 2 is a rectangular plate with a certain thickness, and the first gauge can be a dial indicator or a micrometer indicator. The needle of the first gauge is abutted against the side surface 21 of one long side of the tooling base plate 2. The first moving axis is the moving axis that is 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 moving axis, the reading of the first gauge will fluctuate as the first machine head drives the first gauge to move back and forth along the direction of the first moving axis.
[0080] The operator can control the rotation of the first worktable 31 around the C-axis by turning the handwheel according to the fluctuation range of the first gauge reading, while observing the change in the first gauge reading. 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 moving axis meets the requirements. For example, the second set value is 0mm-0.002mm.
[0081] When assembling the laser tool setter 1 with the fixture base plate 2, the length direction of the laser tool setter 1 is consistent with the length direction of the fixture base plate 2, that is, the direction of the laser beam 11 of the laser tool setter 1 is consistent with the length direction of the fixture base plate 2. In this embodiment, by adjusting the first head of the machine tool 3 to perform a dial indicator test on the side 21 of the fixture base plate 2, the radial deviation of the laser beam 11 relative to the first spindle can be reduced, which is beneficial to improving the calibration accuracy of the axial deviation in subsequent steps.
[0082] Furthermore, after step S11 and before step S2, the following steps are also included:
[0083] Step S12: Control the first machine head to drive the first gauge to reciprocate along the first moving axis of the first main shaft to perform a pull gauge test on the second parallelism of the laser tool setter 1 relative to the first moving axis; tap the side of the laser tool setter 1 according to the reading of the first gauge until the reading of the first gauge is less than or equal to the third set value.
[0084] Specifically, the pointer of the first gauge is brought into contact with the side surface of the laser tool setter 1 along its length. After completing step S11, if the side surface of the laser tool setter 1 is not parallel to the side surface 21 of the fixture base plate 2, the reading of the first gauge will fluctuate as the first head moves the first gauge back and forth along the first moving axis of the first main shaft. Furthermore, the parallelism between the side surface of the laser tool setter 1 and the side surface 21 of the fixture base plate 2 will affect the radial deviation of the laser beam 11 relative to the first main shaft.
[0085] The operator can adjust the second parallelism of the side of the laser tool setter 1 relative to the first moving axis by tapping the side of the laser tool setter 1, based on the fluctuation range of the first gauge reading. This adjusts the radial deviation of the laser beam 11 relative to the first moving axis, while simultaneously observing the change in the first gauge reading. When the change in the reading is less than or equal to the third set value, it indicates that the second parallelism of the laser tool setter 1 relative to the first moving axis meets the requirements.
[0086] Since the radial deviation is adjusted by rotating the first worktable 31 around the C-axis in step S21, the third setting value can be enlarged relative to the set radial deviation value. For example, the third setting value is 0.01mm.
[0087] In this embodiment, the first parallelism of the side surface 21 of the tooling base plate 2 relative to the first moving axis of the first spindle is tested by adjusting the machine tool 3 using a dial indicator. The first parallelism is calibrated by rotating the first worktable 31 around the C-axis. Then, the second parallelism of the side surface of the laser tool setter 1 relative to the first moving axis is tested by adjusting the dial indicator by tapping the laser tool setter 1 to adjust its posture on the tooling base plate 2. This can greatly reduce the radial deviation of the laser beam 11 relative to the first spindle, which is beneficial to improving the calibration accuracy of the axial deviation in the subsequent steps.
[0088] It should be noted that the radial deviation can be calibrated by setting a first and second parallelism standard with higher precision, through steps S11 and S12, and then tested in step S2. In actual debugging, the radial deviation will also be tested in step S22, and then precisely calibrated by controlling the first worktable 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 triggering the alarm program of the debugging machine tool 3 when the radial deviation is too large.
[0089] In this embodiment of the invention, the method further includes the following steps before step S1:
[0090] Step S101: A rectangular plate-shaped component with a regular structure is precision machined, or an existing rectangular plate-shaped component that meets the precision requirements is used. For example... Figure 4 As shown, the rectangular plate has a first mounting surface and a second mounting surface facing away from each other. The first mounting surface is used to mount the laser tool setter 1, and the second mounting surface is used to mount and fix it to the table surface of the first worktable 31. The rectangular plate is made of a high-rigidity material.
[0091] In step S102, multiple bosses 22 are machined on the first mounting surface, and the multiple bosses 22 are spaced apart along the length of the rectangular plate.
[0092] Step S103: Machining mounting holes 23 on the boss 22 that correspond to the threaded holes on the laser tool setter 1.
[0093] In step S102, a portion of the first mounting surface is milled to form multiple bosses 22 on the first mounting surface. These bosses 22 are spaced apart along the length of the tooling base plate 2. The laser tool setter 1 is mounted and fixed to at least two of these bosses 22. In step S3, the axial deviation of the laser beam 11 can be calibrated by milling the multiple bosses 22 of the boss structure.
[0094] Specifically, multiple bosses 22 form at least one set of boss structures, and each set of boss structures includes at least two bosses 22. The spacing between the multiple bosses 22 in different boss structures is different, so that different boss structures can be used to install laser tool setters of different specifications and models. The fixture base plate 2 can be used to assemble with laser tool setters 1 of different specifications and models, and has flexibility and adjustability, and can adapt to different models of machine tools.
[0095] For example, two bosses 22 are machined on the first mounting surface to form a boss structure. Alternatively, four bosses 22 are machined on the first mounting surface to form a first boss structure and a second boss structure. Both the first and second boss structures include two bosses 22. The two bosses 22 of the first boss structure are located at opposite ends of the first mounting surface, while the two bosses 22 of the second boss structure are located on opposite sides of the first mounting surface and between the two bosses 22 of the first boss structure. The first and second boss structures can be used to mount laser tool setters 1 of different sizes.
[0096] In this embodiment of the invention, the tooling base plate 2 is provided with multiple mounting holes 23, and the laser tool setter 1 is provided with multiple through holes, with each through hole corresponding to one of the mounting holes 23. The laser tool setter 1 and the tooling base plate 2 are connected by bolts passing through the mounting holes 23 and the through holes, the outer diameter of which is smaller than the inner diameter of the mounting holes 23.
[0097] Mounting hole 23 is a through hole penetrating both the first and second mounting surfaces. Specifically, mounting hole 23 is a countersunk through hole located on the second mounting surface. In step S1, the laser tool setter 1 is mounted and fixed to the fixture base plate 2 using multiple bolts and nuts, but the nuts are not tightened. This allows for calibration of the second parallelism in step S12 by tapping the side of the laser tool setter 1. After completing step S12, the nuts are tightened to prevent relative movement between the laser tool setter 1 and the fixture base plate 2.
[0098] In other embodiments, the mounting hole 23 is a threaded hole, which can be a through hole penetrating both the first and second mounting surfaces, or a blind hole located on the first mounting surface. The laser tool setter 1 and the fixture base plate 2 are connected by screws passing through the mounting hole 23 and the through hole. The screws are successively inserted into the through hole of the laser tool setter 1 and the mounting hole 23 of the fixture base plate 2, and are threadedly connected to the fixture base plate 2. This improves the positioning accuracy of the laser tool setter 1 and the fixture base plate 2, reduces the amount of readjustment required, allows for fine-tuning, and eliminates the need for nuts, thus saving costs.
[0099] In this embodiment of the invention, step S6 specifically includes:
[0100] Step S61: Install the standard tool onto the second spindle and determine the radial deviation of the laser beam 11 relative to the second spindle based on the standard tool.
[0101] Step S62: Based on the radial deviation of the laser beam 11 relative to the second spindle, adjust the third parallelism of the tooling base plate 2 relative to the second moving axis of the second spindle.
[0102] Step S63, proceed to step S61;
[0103] Step S64: If it is determined that the radial deviation of the laser beam 11 relative to the second spindle 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 spindle is less than or equal to the set radial deviation value.
[0104] In this process, the assembly consisting of the laser tool setter 1 (with axial calibration completed) and the tooling base plate 2 is mounted onto the second worktable of the target machine tool. Step S61 is performed with the second worktable in a 0-0 datum plane state to detect radial deviation. Step S61 can be controlled by a calibration program set within the target machine tool.
[0105] In step S61, a standard tool is mounted on the second spindle of the second mechanism. The movement of the second mechanism is controlled so that the laser tool setter 1 scans the standard tool axially and radially. Based on the scanning structure, the axial and radial deviations of the laser beam 11 relative to the second spindle can be determined. Typically, after steps S1 to S5 of this embodiment, the determined axial deviation of the laser beam 11 relative to the second spindle meets the axial accuracy requirements of the target machine tool; only the radial deviation needs to be calibrated. Specifically, in step S62, the radial deviation is calibrated by adjusting the third parallelism of the tooling base plate 2 relative to the second moving axis of the second spindle.
[0106] After step S62, step S63 is executed, which involves re-detecting the radial deviation using the method described in step S61 to re-determine the radial deviation of the laser beam 11 relative to the second spindle. If the detected radial deviation is less than or equal to the set radial deviation value as determined in step S64, it indicates that the radial deviation has been calibrated to the set standard. If the detected radial deviation is greater than the set radial deviation as determined in step S64, 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.
[0107] Specifically, before step S61, the method further includes: installing the second gauge on the second head of the target machine tool and abutting the measuring end of the second gauge against the side 21 of the tooling base plate 2.
[0108] Step S62 specifically includes: controlling the second machine head and the second worktable of the target machine tool to reciprocate relative to each other in the direction of the second moving axis, and performing a dial indicator test on the third parallelism. The side 21 of the tooling base plate 2 is tapped according to the reading of the second dial indicator until the reading of the second dial indicator reaches the set range.
[0109] Among them, the second moving axis of the second machine head is the moving axis that is closest to the length direction of the tooling base plate 2, and the specific setting depends on the model of the target machine tool.
[0110] Since there is also an axial deviation between the laser tool setter 1 and the fixture base plate 2, this 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 setter 1 and the fixture base plate 2. The set interval can be calculated based on this 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 has reached the set standard.
[0111] Typically, after the axial deviation calibration of the laser tool setter 1 is completed through steps S1 to S5 of this embodiment of the invention, it can be directly mounted onto the target machine tool along with the fixture base plate 2 to meet the set axial deviation value required by the target machine tool. In actual production, after the laser tool setter 1 and the fixture base plate 2 are mounted onto the target machine tool as a whole, another test is 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.
[0112] In this embodiment of the invention, step S61 further includes: determining the axial deviation of the laser beam 11 relative to the second spindle based on a standard tool. After step S61 and before step S62, the method further includes: determining that the axial deviation of the laser beam 11 relative to the second spindle is greater than a set axial deviation value; then, steps S1 to S61 are executed 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.
[0113] If the axial deviation of the laser beam 11 relative to the second spindle, as determined in step S61, does not meet the axial accuracy requirements 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 the axial deviation test in step S61 until the test is qualified, then continue to steps S62 to S64.
[0114] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
