Description

Technical Field

[0001] This utility model relates to the field of laser cutting machine technology, and in particular to a laser cutting machine error detection and correction system. Background Technology

[0002] A laser cutting machine uses a laser beam emitted from a laser source, which is focused into a high-power-density laser beam through an optical path system. The laser beam irradiates the surface of the workpiece, causing the workpiece to reach its melting or boiling point. At the same time, high-pressure gas coaxial with the beam blows away the molten or vaporized metal. As the relative position of the beam and the workpiece moves, a kerf is eventually formed in the material, thus achieving the purpose of cutting.

[0003] When a laser cutting machine is working, the workpiece needs to be placed on the processing table. During the laser cutting process, the workpiece may sometimes shift, resulting in processing errors and reducing the processing quality of the workpiece.

[0004] Therefore, an error detection and correction system for laser cutting machines is proposed. Utility Model Content

[0005] To address the issue of workpiece misalignment that sometimes leads to processing errors, this invention provides a laser cutting machine error detection and correction system.

[0006] This utility model provides a laser cutting machine error detection and correction system, which adopts the following technical solution:

[0007] A laser cutting machine error detection and correction system includes a machine base, an error detection component, and a correction component. The top surface of the machine base has a groove, and a support seat is slidably installed inside the groove. A processing table is slidably installed on the support seat. The error detection component includes a transverse guide rail, a longitudinal guide rail, a transverse sliding block, a longitudinal sliding block, a transverse laser detector, and a longitudinal laser detector. The transverse and longitudinal guide rails are both fixedly installed on the machine base and are perpendicular to each other. Two symmetrical transverse sliding blocks are slidably connected inside the transverse guide rail, and two symmetrical longitudinal sliding blocks are slidably connected inside the longitudinal guide rail. The transverse laser detector is fixedly installed on the transverse sliding block, and the longitudinal laser detector is fixedly installed on the longitudinal sliding block.

[0008] The correction assembly includes a first motor, a transverse screw, a second motor, and a longitudinal screw. The first motor is fixedly mounted on one side of the machine base, and its output end is fixedly connected to one end of the transverse screw. The transverse screw is rotatably mounted in a groove. The support seat is sleeved on the transverse screw and threadedly connected to it. The second motor is fixedly mounted on one side of the support seat, and its output end is fixedly connected to one end of the longitudinal screw. The longitudinal screw is rotatably mounted on the support seat. The processing table is sleeved on the longitudinal screw and threadedly connected to it.

[0009] By adopting the above technical solution and setting the error detection component, during error detection, the lateral sliding block slides along the lateral guide rail, adjusting the two lateral laser detectors to the lateral critical position of the workpiece. The longitudinal sliding block slides along the longitudinal guide rail, adjusting the two longitudinal laser detectors to the longitudinal critical position of the workpiece. When the lateral laser detector detects the workpiece, it indicates that the workpiece has a lateral offset; when the longitudinal laser detector detects the workpiece, it indicates that the workpiece has a longitudinal offset. Through the setting of the correction component, when the lateral laser detector detects a lateral deviation, the first motor can be started to drive the lateral screw to rotate, causing the lateral screw to drive the support seat to move laterally, thereby correcting the workpiece laterally. When the longitudinal laser detector detects a longitudinal deviation, the second motor can be started to drive the longitudinal screw to rotate, causing the longitudinal screw to drive the processing table to move longitudinally, thereby correcting the workpiece longitudinally, reducing processing errors and improving processing quality.

[0010] Optionally, a third motor is fixedly installed at one end of the transverse guide rail, and a transverse double helical screw is fixedly connected to the output end of the third motor. The transverse double helical screw is rotatably installed inside the transverse guide rail, and two transverse sliding blocks are respectively sleeved on both ends of the transverse double helical screw and threadedly connected to the transverse double helical screw.

[0011] By adopting the above technical solution, and by setting up a third motor and a transverse double helical screw, when adjusting the transverse laser detector, it is only necessary to start the third motor to drive the transverse double helical screw to rotate, so that the transverse double helical screw drives the two transverse sliding blocks to move relative to or in opposite directions, thereby adjusting the two transverse laser detectors according to the transverse dimensions of the workpiece.

[0012] Optionally, a fourth motor is fixedly installed at one end of the longitudinal guide rail, and a longitudinal double helical screw is fixedly connected to the output end of the fourth motor. The longitudinal double helical screw is rotatably installed inside the longitudinal guide rail, and two longitudinal sliding blocks are respectively sleeved on both ends of the longitudinal double helical screw and threadedly connected to the longitudinal double helical screw.

[0013] By adopting the above technical solution, and by setting up the fourth motor and the longitudinal double helical screw, when adjusting the longitudinal laser detector, it is only necessary to start the fourth motor to drive the longitudinal double helical screw to rotate, so that the longitudinal double helical screw drives the two longitudinal sliding blocks to move relative to or in opposite directions, and the two longitudinal laser detectors can be adjusted according to the transverse dimensions of the workpiece.

[0014] Optionally, the tops of both the transverse sliding block and the longitudinal sliding block are fixedly connected to mounting bases, and both the transverse laser detector and the longitudinal laser detector can be detachably installed in the mounting bases.

[0015] By adopting the above technical solution, the horizontal laser detector and the vertical laser detector can be disassembled.

[0016] Optionally, the top of the mounting base is threaded with a fastening bolt.

[0017] By adopting the above technical solution, the transverse laser detector and the longitudinal laser detector can be fixed by fastening bolts.

[0018] Optionally, a transverse guide rod is fixedly installed on both sides of the groove, and the support seat is slidably sleeved on the transverse guide rod.

[0019] By adopting the above technical solution, the lateral guide rod can play a lateral guiding role for the support base.

[0020] Optionally, longitudinal guide rods are fixedly installed on both sides of the support base, and the processing table is slidably sleeved on the longitudinal guide rods.

[0021] By adopting the above technical solution, the longitudinal guide rod can play a longitudinal guiding role on the processing table.

[0022] Optionally, a controller is provided on the base, and the transverse laser detector, longitudinal laser detector, first motor, second motor, third motor and fourth motor are all electrically connected to the controller.

[0023] By adopting the above technical solution, the detection results of the horizontal laser detector and the vertical laser detector can be fed back to the controller, and the controller can then control the first motor, the second motor, the third motor and the fourth motor.

[0024] In summary, this utility model has the following beneficial effects:

[0025] 1. This utility model, through the setting of the error detection component, during error detection, slides the transverse sliding block along the transverse guide rail and adjusts the two transverse laser detectors to the transverse critical position of the workpiece, slides the longitudinal sliding block along the longitudinal guide rail and adjusts the two longitudinal laser detectors to the longitudinal critical position of the workpiece. When the transverse laser detector detects the workpiece, it indicates that the workpiece has undergone transverse displacement; when the longitudinal laser detector detects the workpiece, it indicates that the workpiece has undergone longitudinal displacement.

[0026] 2. By setting up a correction component, this utility model can start a first motor to drive the transverse screw to rotate when the transverse laser detector detects a transverse deviation, so that the transverse screw drives the support seat to move laterally, thereby correcting the workpiece laterally.

The 13 is sleeved on the longitudinal screw 34 and threadedly connected to the longitudinal screw 34. With the setting of the correction component 3, when the transverse laser detector 25 detects a transverse deviation, the first motor 31 can be started to drive the transverse screw 32 to rotate, so that the transverse screw 32 drives the support seat 12 to move laterally, thereby correcting the workpiece laterally.

The longitudinal sliding block 24 slides along the longitudinal guide rail 22, and the two longitudinal laser detectors 26 are adjusted to the longitudinal critical position of the workpiece. When the transverse laser detector 25 detects the workpiece, it indicates that the workpiece has a transverse offset. When the longitudinal laser detector 26 detects the workpiece, it indicates that the workpiece has a longitudinal offset. With the correction component 3, when the transverse laser detector 25 detects a transverse deviation, the first motor 31 can be started to drive the transverse screw 32 to rotate, causing the transverse screw 32 to drive the support base 12 to move laterally, thereby correcting the workpiece laterally. When the longitudinal laser detector 26 detects a longitudinal deviation, the second motor 33 can be started to drive the longitudinal screw 34 to rotate, causing the longitudinal screw 34 to drive the processing table 13 to move longitudinally, thereby correcting the workpiece longitudinally, reducing processing errors, and improving processing quality.
