Description

Technical Field

[0001] This invention relates to the technical field of laser marking machine tools, and in particular to a precision guide rail positioning device for a laser marking machine tool used in sheet metal production. Background Technology

[0002] When installing the guide rail of a laser marking machine tool for sheet metal production, precise positioning is required before installation. Chinese invention patent CN115488492B discloses a guide rail installation device and its straightening method for a laser machine tool. This device includes a machine tool body, a guide rail on the guide rail installation plane of the machine tool body, and a guide rail straightness adjustment device on the side plane of the machine body. This device includes a steel strip tensioning mechanism, a steel strip position adjustment mechanism, and a steel strip clamped between the tensioning and position adjustment mechanisms at both ends of the guide rail. A guide rail straightness detection and calibration mechanism is connected to the guide rail. This invention uses a steel strip instead of the marble parallel ruler used in the prior art, avoiding the use of heavy marble and reducing repeated calibrations caused by the repeated handling of the marble parallel ruler. This saves time and reduces the manufacturing cost of the machine tool. While ensuring straightening accuracy, it can spend less time and money, improving straightening efficiency. It is suitable for use in high-precision machine tool guide rail straightening devices with increased long axis lengths.

[0003] However, the above-mentioned guide rail installation device uses a taut steel strip as the benchmark for straightening and positioning. When the guide rail is short, the steel strip is also short. At this time, the steel strip bends less downward in the middle due to gravity, resulting in higher straightening and positioning accuracy. When the guide rail is long, the steel strip is also long. At this time, the steel strip bends more downward in the middle due to gravity, resulting in reduced straightening and positioning accuracy. Therefore, it needs to be improved. Summary of the Invention

[0004] To solve the above-mentioned technical problems, the present invention provides a precision guide rail positioning device for a laser marking machine tool for sheet metal production, which improves the straightening and positioning accuracy by employing two-stage straightening and positioning, and whose guide rail positioning accuracy is not limited by length.

[0005] This invention discloses a precision guide rail positioning device for a laser marking machine tool used in sheet metal production. The device includes a machine tool panel and guide rails. Multiple guide rail mounting holes are arranged in a matrix on the machine tool panel, forming a row. Bolt holes matching the mounting holes are provided on the guide rails. The device also includes a laser emitter, a vertical plate, multiple vertical rods, multiple blocks, a fixed reflector mount, a slider, and a movable reflector mount. The laser emitter and the fixed reflector mount are mounted on the machine tool panel. The laser emitter is located in front of the first guide rail mounting hole. The vertical plate is mounted on the laser emitter, and a vertical slit is provided in the middle of the vertical plate. The fixed reflector mount is located behind the last guide rail mounting hole. The multiple blocks are respectively mounted on… Multiple vertical rods and blocks form a light guide assembly. Horizontal holes are set on the blocks. Two vertical rods are concentrically inserted into the first and last guide rail mounting holes, respectively. The horizontal holes of the two blocks are concentrically aligned. The position and angle of the laser emitter and the fixed reflector are adjusted so that the horizontal laser beam emitted by the laser emitter passes through the horizontal holes of the two blocks in sequence and illuminates the fixed reflector. The fixed reflector reflects the laser beam into the narrow slit of the vertical plate, making the horizontal laser beam emitted by the laser emitter a calibration and positioning reference light. The slider is slidably mounted on the guide rail, and the movable reflector is mounted on the slider. The movable reflector reflects the reference light into the narrow slit of the vertical plate.During operation, the angle and position of the moving reflector mount relative to the slider are corrected. Two light guide assemblies are selected, and the two vertical rods of each light guide assembly are concentrically inserted into the first and last guide rail mounting holes on the machine tool panel, respectively. The height and angle of the two blocks are adjusted so that the horizontal holes of the two blocks are concentrically aligned. At this point, the axes of the horizontal holes of the two blocks are horizontally collinear and parallel to the machine tool panel, forming a line segment with the center of the first and last guide rail mounting holes as endpoints. The position and angle of the laser emitter are adjusted so that the horizontal laser beam emitted by the laser emitter passes through the horizontal holes of the two blocks in sequence and illuminates the target area. On the fixed reflector mount, adjust the position and angle of the fixed reflector mount so that the laser beam reflected by the fixed reflector mount illuminates the narrow slit of the vertical plate. Remove the two light guide components. At this point, the horizontal laser beam is the reference light for precise alignment and positioning. Use multiple bolts to movably mount the guide rail onto the multiple guide rail mounting holes on the machine tool panel. Concentrically install the aforementioned multiple light guide components into the multiple empty bolt holes on the guide rail. Adjust the position and angle of the guide rail, and simultaneously adjust the height and angle of the multiple blocks so that the reference light passes through the horizontal holes of the multiple blocks in sequence, thereby initially positioning the guide rail. Slightly tighten the multiple bolts on the guide rail to pre-tighten the guide rail, and then install the multiple light guide components. Remove the component from the guide rail and slightly tighten several bolts in the empty bolt holes. Now the guide rail is filled with bolts. Slide the slider onto the guide rail so that the reference light shines on the moving reflector mount. A crosshair is set on the moving reflector mount, and the intersection of the crosshairs is the center point of the moving reflector mount. The moving reflector mount reflects the reference light towards the vertical plate. When the reference light shines on the left and right sides of the center of the moving reflector mount, the guide rail shifts left and right at this point. When the reference light shines on the top and bottom sides of the center of the moving reflector mount, the guide rail shifts up and down at this point. When the light reflected by the moving reflector mount cannot shine on the narrow slit of the vertical plate, the guide rail twists along its axis at this point. The guide rail is adjusted in angle and position according to the different situations described above, so that the reference light shines on the center of the moving reflector mount, and the light reflected by the moving reflector mount shines on the narrow slit of the vertical plate. This allows for precise straightening and positioning of the guide rail. The slider is moved along the guide rail, and the entire guide rail is precisely straightened and positioned, ensuring that the reference light shines on the center of the moving reflector mount and the light reflected by the moving reflector mount shines on the narrow slit of the vertical plate, regardless of the slider's position on the guide rail. All bolts are tightened to fix the guide rail in place. Compared to existing technologies, the positioning accuracy of the guide rail is not limited by length. The two-stage straightening and positioning improves the accuracy of straightening and positioning.

[0006] Preferably, it also includes two magnetic bases. Magnetic bases are installed at the bottom of both the laser emitter and the fixed reflector base. The laser emitter and the fixed reflector base are magnetically attracted to the machine tool panel through the two magnetic bases. When adjusting the position of the laser emitter and the fixed reflector base, the knobs of the two magnetic bases are turned to eliminate the magnetic force, allowing the laser emitter and the fixed reflector base to move. After the position of the laser emitter and the fixed reflector base is adjusted, the knobs of the two magnetic bases are turned to generate magnetic attraction to the machine tool panel. The technology is mature and the operation is flexible.

[0007] Preferably, it also includes a horizontal plate and multiple mounting bolts. The horizontal plate is installed at the lower end of the vertical plate, and the horizontal plate is installed on the laser emitter by multiple mounting bolts. By setting the horizontal plate and multiple mounting bolts, it is convenient to install and disassemble the vertical plate.

[0008] Preferably, it also includes a vertical shaft, a rack, a gear shaft, and a handwheel. The vertical shaft is installed on the lower end face of the block, and a rack is provided on the side wall of the vertical shaft. The vertical shaft is slidably inserted into the vertical rod and can be raised and lowered. The gear shaft is rotatably installed on the vertical rod and meshes with the rack. The handwheel is installed on the end of the gear shaft. By rotating the gear shaft with the handwheel, the gear shaft meshes with the rack and drives the vertical shaft to rise and fall along the vertical rod, thereby adjusting the height of the block. It is very practical.

[0009] Preferably, it also includes multiple limiting rings, which are respectively installed on the outer walls of multiple vertical rods; by installing the limiting rings on the outer walls of the vertical rods, the limiting rings limit the vertical rods after they are inserted into the bolt holes of the guide rail, which facilitates the quick installation of the vertical rods.

[0010] Preferably, a standard slide rail is also included, which has the same specifications as the guide rail. The length of the standard slide rail is shorter than that of the guide rail. After the horizontal laser line emitted by the laser emitter is adjusted into a reference beam, the standard slide rail is placed on the machine tool panel. The two light guide assemblies are concentrically installed in the first and last bolt holes of the standard slide rail, respectively. The position and angle of the standard slide rail are adjusted so that the reference beam passes through the horizontal holes of the two square blocks of the two light guide assemblies in sequence. The standard slide rail is then bolted to the machine tool panel. The slider is slidably installed on the standard slide rail. The angle of the moving reflector is adjusted so that when the slider is at any position on the standard slide rail, the reference beam illuminates the center of the moving reflector and the light reflected by the moving reflector illuminates the narrow slit of the vertical plate. This completes the precise correction and positioning of the relative position of the moving reflector and the slider. At this point, the slider is removed from the standard slide rail, the standard slide rail is disassembled, and the precise straightening and positioning installation of the guide rail begins, improving the accuracy of the moving reflector.

[0011] Preferably, it also includes a base plate and a turntable. The base plate is detachably mounted on the slider, the turntable is mounted on the base plate, and the movable reflector mount is mounted on the rotating end of the turntable. Rotating the rotating end of the turntable causes the movable reflector mount to rotate, which facilitates the adjustment of the relative angle between the movable reflector mount and the slider.

[0012] Preferably, it also includes a gear ring, a bearing housing, and a second gear. The gear ring is concentrically mounted on the outer wall of the rotating end of the turntable, the bearing housing is mounted on the base plate, and the second gear is rotatably mounted on the bearing housing, meshing with the gear ring. A connecting piece is concentrically set on the second gear. By using a wrench or other general-purpose tool to rotate the second gear, the second gear meshes with the gear ring, driving the rotating end of the turntable to rotate, so that the rotating end of the turntable drives the reflector mount to adjust the angle. It is convenient to operate and has good practicality.

[0013] Preferably, it also includes a side frame and a rangefinder. The side frame is mounted on the base plate, and the rangefinder is mounted on the side frame. The rangefinder is used to measure the distance between the slider and the laser emitter, which facilitates the recording of the positioning accuracy at different length positions on the guide rail, thereby evaluating the precise positioning effect of the guide rail and issuing an accuracy verification report.

[0014] Preferably, it also includes a photosensitive element, which is mounted on the upright plate and located on the back of the vertical narrow slit of the upright plate. When the reference light reflected by the fixed reflector and the moving reflector shines on the narrow slit of the upright plate, the reflected light shines through the narrow slit onto the photosensitive element, and the photosensitive element generates an electrical signal. The indicator light on the upright plate that is electrically connected to the photosensitive element lights up, which is more intuitive and facilitates the precise calibration and positioning of the guide rail.

[0015] Compared with the prior art, the beneficial effects of the present invention are: the positioning accuracy of the guide rail is not limited by the length, and the two-stage straightening and positioning improves the straightening and positioning accuracy. Attached Figure Description

[0028] To facilitate understanding of the present invention, a more complete description will be given below with reference to the accompanying drawings. The present invention can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete. Example 1

[0029] like Figure 1 , Figure 2 , Figure 3 , Figure 5 , Figure 6 , Figure 7 , Figure 8 and Figure 10As shown, a precision guide rail positioning device for a laser marking machine tool for sheet metal production includes a machine tool panel 1 and a guide rail 2. The machine tool panel 1 has multiple guide rail mounting holes arranged in a matrix, and the guide rail 2 has bolt holes that match the mounting holes. The device also includes a laser emitter 3, a vertical plate 4, multiple vertical rods 5, multiple blocks 6, a fixed reflector mount 7, a slider 8, and a movable reflector mount 9. The laser emitter 3 and the fixed reflector mount 7 are mounted on the machine tool panel 1. The laser emitter 3 is located in front of the first guide rail mounting hole. The vertical plate 4 is mounted on the laser emitter 3, and a vertical narrow slit is provided in the middle of the vertical plate 4. The fixed reflector mount 7 is located behind the last guide rail mounting hole. The multiple blocks 6 are respectively mounted on the multiple vertical rods 5, and the vertical rods 5 and blocks 6 constitute a light guide assembly. Horizontal holes are provided on the blocks 6. Two vertical rods 5 are concentrically inserted into the first and last guide rail mounting holes, respectively. The horizontal holes of the two blocks 6 are concentrically aligned. Adjustment of the laser emission... The positions and angles of the laser emitter 3 and the fixed reflector mount 7 are such that the horizontal laser beam emitted by the laser emitter 3 passes sequentially through the horizontal holes of the two square blocks 6 and irradiates the fixed reflector mount 7. The fixed reflector mount 7 reflects the laser beam into the narrow slit of the vertical plate 4, making the horizontal laser beam emitted by the laser emitter 3 a calibration and positioning reference light. The slider 8 is slidably mounted on the guide rail 2, and the movable reflector mount 9 is mounted on the slider 8. The movable reflector mount 9 reflects the reference light into the narrow slit of the vertical plate 4. It also includes two magnetic seats 26. Magnetic seats 26 are installed at the bottom of both the laser emitter 3 and the fixed reflector mount 7. The laser emitter 3 and the fixed reflector mount 7 are magnetically attracted to the machine tool panel 1 by the two magnetic seats 26. It also includes a horizontal plate 10 and multiple mounting bolts 11. The horizontal plate 10 is installed at the lower end of the vertical plate 4. The horizontal plate 10 is mounted on the laser emitter 3 by multiple mounting bolts 11. It also includes a photosensitive element 25. The photosensitive element 25 is mounted on the vertical plate 4 and is located on the back of the vertical narrow slit of the vertical plate 4.

[0030] During operation, the angle and position of the moving reflector mount 9 relative to the slider 8 are corrected. Two light guide components are selected, and the two vertical rods 5 of the two light guide components are concentrically inserted into the first and last guide rail mounting holes on the machine tool panel 1, respectively. The height and angle of the two blocks 6 are adjusted so that the horizontal holes of the two blocks 6 are concentrically aligned. At this time, the axes of the horizontal holes of the two blocks 6 are horizontally collinear and parallel to the machine tool panel 1, forming a line segment with the center of the first guide rail mounting hole and the center of the last guide rail mounting hole as endpoints. The knobs of the two magnetic seats 26 are turned to remove the magnetism, allowing the laser emitter 3 and the fixed reflector mount 7 to move. The position and angle of the laser emitter 3 are adjusted so that the horizontal laser beam emitted by the laser emitter 3 passes through the machine tool panel 1 in sequence. The two squares 6 have horizontal holes that illuminate the fixed reflector mount 7. The position and angle of the fixed reflector mount 7 are adjusted so that the laser beam reflected by the fixed reflector mount 7 illuminates the narrow slit in the vertical plate 4. After the laser emitter 3 and the fixed reflector mount 7 are adjusted, the knobs of the two magnetic seats 26 are turned to generate magnetic attraction onto the machine tool panel 1. The two light guide components are then removed. At this point, the horizontal laser beam serves as the reference light for precise alignment and positioning. The guide rail 2 is movably mounted on the multiple guide rail mounting holes of the machine tool panel 1 using multiple bolts. The aforementioned multiple light guide components are concentrically installed in the multiple empty bolt holes on the guide rail 2. The position and angle of the guide rail 2 are adjusted, and simultaneously the height and angle of the multiple squares 6 are adjusted so that the reference light beam passes sequentially through the horizontal holes of the multiple squares 6. Small holes are made to initially position the guide rail 2. Several bolts on the guide rail 2 are slightly tightened to pre-tighten it. Several light guide components are removed from the guide rail 2. Several bolts in the empty bolt holes are slightly tightened, filling the bolt holes of the guide rail 2. The slider 8 is then slidably mounted on the guide rail 2, allowing the reference light to illuminate the moving reflector mount 9. A crosshair is set on the moving reflector mount 9, with the intersection of the crosshairs being the center point of the moving reflector mount 9. The moving reflector mount 9 reflects the reference light towards the vertical plate 4. When the reference light illuminates the left and right sides of the center of the moving reflector mount 9, the guide rail 2 shifts left and right at these points. When the reference light illuminates the upper and lower sides of the center of the moving reflector mount 9, the guide rail 2 shifts up and down at these points. When the light reflected by the moving reflector mount 9 cannot illuminate... When the guide rail 2 is in the narrow slit of the vertical plate 4, it twists along the axis. The angle and position of the guide rail 2 are adjusted accordingly based on the different situations described above, so that the reference light shines on the center of the moving reflector mount 9, and the light reflected by the moving reflector mount 9 shines into the narrow slit of the vertical plate 4, passing through the slit and onto the photosensitive element 25. The photosensitive element 25 generates an electrical signal, and the indicator light on the vertical plate 4, electrically connected to the photosensitive element 25, illuminates, making the process more intuitive. This allows for precise alignment and positioning of the guide rail 2. The slider 8 is moved along the guide rail 2, and the guide rail 2 is precisely aligned and positioned as a whole, ensuring that the reference light shines on the center of the moving reflector mount 9 and the light reflected by the moving reflector mount 9 shines into the narrow slit of the vertical plate 4, regardless of the position of the slider 8 on the guide rail 2.Tighten all bolts to secure guide rail 2. Compared to existing technologies, guide rail 2's positioning accuracy is not limited by length. It employs a two-stage straightening and positioning process to improve straightening and positioning accuracy.

[0031] It also includes a side frame 23 and a rangefinder 24. The side frame 23 is mounted on the base plate 18, and the rangefinder 24 is mounted on the side frame 23. The rangefinder 24 is used to measure the distance between the slider 8 and the laser emitter 3, so as to record the positioning accuracy at different length positions on the guide rail 2, thereby evaluating the precise positioning effect of the guide rail 2 and issuing an accuracy verification report. Example 2

[0032] like Figure 10 and Figure 11 As shown, based on Embodiment 1, it also includes a vertical shaft 12, a rack 13, a gear shaft 14, and a handwheel 15. The vertical shaft 12 is installed on the lower end face of the block 6, and the rack 13 is provided on the side wall of the vertical shaft 12. The vertical shaft 12 is slidably inserted into the vertical rod 5. The gear shaft 14 is rotatably installed on the vertical rod 5 and meshes with the rack 13. The handwheel 15 is installed on the end of the gear shaft 14. It also includes multiple limiting rings 16, which are respectively installed on the outer walls of multiple vertical rods 5.

[0033] The gear shaft 14 is rotated by the handwheel 15, and the gear shaft 14 meshes with the rack 13 to drive the vertical shaft 12 to rise and fall along the vertical rod 5, thereby adjusting the height of the block 6. This is practical. By installing a limiting ring 16 on the outer wall of the vertical rod 5, the limiting ring 16 limits the vertical rod 5 after it is inserted into the bolt hole of the guide rail 2, which facilitates the quick installation of the vertical rod 5. Example 3

[0034] like Figure 4 , Figure 8 and Figure 9 As shown, based on Embodiment 1, it also includes a standard slide rail 17, which has the same specifications as the guide rail 2; it also includes a base plate 18 and a turntable 19, the base plate 18 is detachably mounted on the slider 8, the turntable 19 is mounted on the base plate 18, and the moving reflector seat 9 is mounted on the rotating end of the turntable 19; it also includes a gear ring 20, a bearing seat 21, and a second gear 22, the gear ring 20 is concentrically mounted on the outer wall of the rotating end of the turntable 19, the bearing seat 21 is mounted on the base plate 18, and the second gear 22 is rotatably mounted on the bearing seat 21, and the second gear 22 meshes with the gear ring 20.

[0035] The standard slide rail 17 is shorter than the guide rail 2. After the horizontal laser line emitted by the laser emitter 3 is adjusted to the reference beam, the standard slide rail 17 is placed on the machine tool panel 1. The two light guide assemblies are concentrically installed in the first and last bolt holes of the standard slide rail 17, respectively. The position and angle of the standard slide rail 17 are adjusted so that the reference beam passes through the horizontal holes of the two square blocks 6 of the two light guide assemblies in sequence. The standard slide rail 17 is then bolted to the machine tool panel 1. The slider 8 is slidably installed on the standard slide rail 17. Connecting parts are concentrically set on the gear 22. The gear 22 is rotated using a wrench or other general-purpose tools. Gear 22 meshes with gear ring 20 to drive the rotating end of turntable 19 to rotate, causing the rotating end of turntable 19 to drive the moving reflector seat 9 to adjust its angle. This facilitates the adjustment of the relative angle between the moving reflector seat 9 and the slider 8, ensuring that when the slider 8 is at any position on the standard slide rail 17, the reference light shines on the center of the moving reflector seat 9, and the light reflected by the moving reflector seat 9 shines into the narrow slit of the vertical plate 4. This completes the precise correction and positioning of the relative position of the moving reflector seat 9 and the slider 8. At this point, the slider 8 is removed from the standard slide rail 17, the standard slide rail 17 is disassembled, and the precise straightening and positioning installation of the guide rail 2 begins, improving the accuracy of the moving reflector seat 9.

[0036] like Figures 1 to 11As shown, the present invention discloses a precision guide rail positioning device for a laser marking machine tool for sheet metal production. During operation, two light guide components are first selected, and the two vertical rods 5 of each component are concentrically inserted into the first and last guide rail mounting holes on the machine tool panel 1. The height and angle of the two blocks 6 are adjusted so that the horizontal holes of the two blocks 6 are concentrically aligned. At this point, the axes of the horizontal holes of the two blocks 6 are horizontally collinear and parallel to the machine tool panel 1, forming a line segment with the center of the first and last guide rail mounting holes as endpoints. The position and angle of the laser emitter 3 are adjusted so that the horizontal laser beam emitted by the laser emitter 3 passes sequentially through the horizontal holes of the two blocks 6 and irradiates the fixed reflector mount 7. The position and angle of the fixed reflector mount 7 are then adjusted so that the laser beam reflected by the fixed reflector mount 7 irradiates the narrow slit of the vertical plate 4, thus positioning the two guide rails... After removing the optical components, the horizontal laser beam becomes the reference light for precise alignment and positioning. Then, the standard slide rail 17 is placed on the machine tool panel 1. The two light guides are concentrically installed in the first and last bolt holes of the standard slide rail 17, respectively. The position and angle of the standard slide rail 17 are adjusted so that the reference light passes through the horizontal holes of the two square blocks 6 of the two light guides in sequence. The standard slide rail 17 is then bolted to the machine tool panel 1. The slider 8 is slidably installed on the standard slide rail 17. The angle of the moving reflector seat 9 is adjusted so that when the slider 8 is at any position on the standard slide rail 17, the reference light shines on the center of the moving reflector seat 9 and the light reflected by the moving reflector seat 9 shines into the narrow slit of the vertical plate 4. This completes the precise correction and positioning of the relative position of the moving reflector seat 9 and the slider 8. At this point, the slider 8 is removed from the standard slide rail 17, and the standard slide rail 17 is disassembled.Then, guide rail 2 is movably mounted on multiple guide rail mounting holes on machine tool panel 1 using multiple bolts. Multiple light guide components are concentrically installed in the empty bolt holes on guide rail 2. The position and angle of guide rail 2 are adjusted, and the height and angle of multiple blocks 6 are adjusted simultaneously, so that the reference light rays pass sequentially through the horizontal holes of multiple blocks 6, thereby initially positioning guide rail 2. Multiple bolts on guide rail 2 are slightly tightened to pre-tighten guide rail 2. Multiple light guide components are removed from guide rail 2. Multiple bolts in the empty bolt holes are slightly tightened, at which point the bolt holes of guide rail 2 are filled with bolts. Sliding slider 8 is then mounted on guide rail 2, allowing the reference light rays to illuminate the moving reflector. The guide rail 2 is adjusted accordingly, with the reference light beam reflected from the movable reflector 9 onto the vertical plate 4. The reference light beam is then positioned so that it illuminates the center of the movable reflector 9 and the reflected light beam illuminates the narrow slit in the vertical plate 4. This ensures precise alignment and positioning of the guide rail 2. Finally, the slider 8 is moved along the guide rail 2, and the guide rail 2 is precisely aligned and positioned as a whole. This ensures that the reference light beam illuminates the center of the movable reflector 9 and the reflected light beam illuminates the narrow slit in the vertical plate 4 regardless of the slider 8's position on the guide rail 2. All bolts are then tightened to secure the guide rail 2. The slider 8 can then be removed.

[0037] The main functions achieved by this invention are:

[0038] 1. The positioning accuracy of guide rail 2 is not limited by its length, and it adopts two-stage straightening and positioning to improve the straightening and positioning accuracy;

[0039] 2. The height and angle of the light guide component can be flexibly adjusted, making it highly versatile;

[0040] 3. By using the standard slide rail 17 to calibrate the moving reflector mount 9 and the slider 8, the accuracy of the moving reflector mount 9 in calibrating and positioning the guide rail 2 is improved.

[0041] 4. By setting crosshairs on the moving reflector mount 9 and setting photosensitive elements 25 on the vertical plate 4, the adjustment effect is more intuitive, which facilitates the precise correction and positioning of the guide rail 2.

[0042] The precision guide rail positioning device for a laser marking machine tool for plate production of the present invention uses common mechanical methods for installation, connection, or setting. Any method that can achieve the beneficial effect can be implemented. The machine tool panel 1, guide rail 2, laser emitter 3, upright plate 4, vertical rod 5, block 6, fixed reflector seat 7, slider 8, moving reflector seat 9, mounting bolt 11, vertical shaft 12, rack 13, gear shaft 14, standard slide rail 17, turntable 19, gear ring 20, bearing seat 21, gear 22, rangefinder 24, photosensitive element 25, and magnetic seat 26 of the precision guide rail positioning device for a laser marking machine tool for plate production of the present invention are commercially available. Technical personnel in this industry only need to install and operate it according to the accompanying instruction manual, without requiring any creative work from those skilled in the art.

[0043] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.

The vertical plate (4) is mounted on the laser emitter (3). A vertical narrow slit is provided in the middle of the vertical plate (4). The fixed reflector mount (7) is located behind the last guide rail mounting hole. Multiple blocks (6) are respectively mounted on multiple vertical rods (5). The vertical rods (5) and blocks (6) constitute a light guide assembly. Horizontal small holes are provided on the blocks (6). Two vertical rods (5) are respectively mounted on multiple vertical rods (5). The two blocks (6) are concentrically inserted into the first and last guide rail mounting holes. The horizontal holes of the two blocks (6) are concentrically aligned. The position and angle of the laser emitter (3) and the fixed reflector (7) are adjusted so that the horizontal laser beam emitted by the laser emitter (3) passes through the horizontal holes of the two blocks (6) and shines on the fixed reflector (7). The fixed reflector (7) reflects the laser beam into the narrow slit of the vertical plate (4) so ​​that the horizontal laser beam emitted by the laser emitter (3) is the calibration and positioning reference light. The slider (8) is slidably installed on the guide rail (2). The moving reflector (9) is installed on the slider (8). The moving reflector (9) reflects the reference light into the narrow slit of the vertical plate (4). Two-stage straightening and positioning are adopted: the guide rail (2) is movably installed on the multiple guide rail mounting holes on the machine tool panel (1) using multiple bolts. The multiple light guide components are concentrically installed in the multiple empty bolt holes on the guide rail (2). The position and angle of the guide rail (2) are adjusted, and the height and angle of the multiple blocks (6) are adjusted at the same time so that the reference light passes through the horizontal small holes of the multiple blocks (6) in sequence, thereby performing preliminary positioning of the guide rail (2). The multiple light guide components are removed from the guide rail (2), and the slider (8) is slidably installed on the guide rail (2) so that the reference light shines on the guide rail (2). The light is projected onto the moving reflector mount (9), which has a crosshair. The intersection of the crosshairs is the center of the moving reflector mount (9). The moving reflector mount (9) reflects the reference light toward the vertical plate (4). The angle and position of the guide rail (2) are adjusted so that the reference light is projected onto the center of the moving reflector mount (9) and the light reflected by the moving reflector mount (9) is projected into the narrow slit of the vertical plate (4).
