Description

Technical Field

[0001] This utility model relates to the field of laser cutting technology, and in particular to auxiliary tooling for laser cutting machine calibration. Background Technology

[0002] Laser cutting technology, as an important processing method in modern manufacturing, is widely used in the cutting of materials such as metals and plastics due to its high precision, high efficiency and non-contact processing characteristics. However, the quality of laser cutting is highly dependent on the calibration accuracy before cutting, especially the accurate positioning of the ray lamp (i.e., laser pointer), which directly affects the accuracy of the cutting path. The traditional calibration process usually relies on manual operation, which is not only time-consuming and labor-intensive, but also easily affected by human factors, resulting in insufficient repeatability. With the increasing demand for industrial automation, higher requirements are placed on the auxiliary calibration tooling of laser cutting machines.

[0003] Currently, most calibration auxiliary fixtures for laser cutting machines use mechanical clamping or magnetic adsorption to fix the X-ray lamp. Mechanical clamping structures typically lock the X-ray lamp directly with bolts or clips, using friction to achieve fixation. Magnetic adsorption relies on the magnetic force between the magnet and the metal shell to complete positioning. During calibration, operators need to manually adjust the angle and position of the X-ray lamp and verify its matching degree with the cutting path by visual inspection or simple measuring tools such as rulers or levels.

[0004] The main problem with existing technologies is that the position of the X-ray lamp needs to be repeatedly measured and adjusted manually during the calibration process, which makes the operation cumbersome and the accuracy difficult to guarantee. Due to the lack of an efficient clamping and release mechanism, operators often need to disassemble multiple fasteners when changing or adjusting the X-ray lamp, which not only prolongs the preparation time, but also easily introduces errors due to repeated installation. In addition, manual calibration relies on experience and is easily affected by visual errors and operating techniques, especially in batch processing where it is difficult to maintain consistency. Utility Model Content

[0005] The purpose of this invention is to provide auxiliary tooling for laser cutting machine calibration, aiming to improve the problem of repeated manual measurement and adjustment of the position of the ray lamp during the calibration process in the prior art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A laser cutting machine calibration auxiliary fixture includes a support frame, a cutting table fixedly connected to the top of the support frame, a moving component on the top of the support frame, a cutting component on the side wall of the moving component, a connecting frame fixedly connected to the side wall of the cutting component, a circular clamp rotatably connected inside the connecting frame, and a calibration component inside the circular clamp. The calibration assembly includes a radiation lamp slidably connected to the inner wall of the circular clamp, the outer wall of the radiation lamp being in contact with the inner wall of the circular clamp, a pressing handle fixedly connected to the side wall of the circular clamp, a spring provided at the bottom of the pressing handle, one end of the spring being fixedly connected to the bottom of the pressing handle, and the other end of the spring being fixedly connected to the side wall of the connecting frame, a baffle fixedly connected to the side wall of the laser instrument, a sliding plate slidably connected inside the cutting table, a fixed frame fixedly connected to the top of the sliding plate, and a positioning assembly provided inside the fixed frame; Optionally, the movable component includes a sliding frame slidably connected to the top of the support frame; Optionally, the cutting assembly includes a laser and a laser cutting head, the laser being slidably connected to the side wall of the sliding frame, and the laser cutting head being disposed at the bottom of the laser; Optionally, the positioning component includes a pressure plate frame, which is rotatably connected inside the fixed frame; Optionally, a hydraulic cylinder is fixedly connected inside the sliding plate, and a disc column is fixedly connected to the output end of the hydraulic cylinder; Optionally, a rotating rod is rotatably connected to the outer wall of the disc column, and one end of the rotating rod is rotatably connected inside the pressure plate frame; Optionally, the rotating rod and the disc column are both slidably connected inside the cutting table, and the pressure plate frame is slidably connected inside the cutting table.

[0007] The above-mentioned technical solutions in the laser cutting machine calibration auxiliary tooling provided in this embodiment of the utility model have at least one of the following technical effects: 1. In this utility model, an auxiliary calibration is performed by installing a ray lamp on a laser cutting machine. At the same time, the ray lamp can rotate the ring clamp inside the connecting frame by pressing the pressing handle, and at the same time compress the spring. Then, the ray lamp is placed inside the ring clamp for limiting, and then positioned by a baffle. This achieves the effect of quickly installing or removing the ray lamp for auxiliary calibration as needed, solving the problems of instability and large error in manual calibration of traditional equipment, and improving the convenience and accuracy of calibration.

[0008] 2. In this utility model, by pushing the sliding plate to slide within the cutting table, the fixed frame is moved to adjust the distance between it and the object being cut. Then, the hydraulic cylinder is activated to move the disc column, which in turn drives the rotating rod to rotate. The rotating rod then drives the pressure plate frame to rotate within the fixed frame and press the object firmly, thereby achieving the effect of stabilizing and fixing the object being cut. This solves the problem of object displacement during the cutting process and improves the stability of the cutting. Attached Figure Description

The ray lamp 8 is slidably connected to the inner wall of the ring clamp 9, and the outer wall of the ray lamp 8 is in contact with the inner wall of the ring clamp 9 to ensure that the ray lamp 8 remains stable during adjustment. A pressing handle 10 is fixedly connected to the side wall of the ring clamp 9. The pressing handle 10 is used for manual operation to control the clamping or loosening state of the ring clamp 9. A spring 11 is provided at the bottom of the pressing handle 10 to provide elastic restoring force to achieve the automatic clamping function. One end of the spring 11 is fixedly connected to the bottom of the pressing handle 10. The other end of the spring 11 is fixedly connected to the side wall of the connecting frame 7. A baffle 17 is fixedly connected to the side wall of the laser instrument 5. The inside of the baffle 17 contacts the outer wall of the X-ray lamp 8 to prevent the X-ray lamp 8 from sliding down due to gravity. A sliding plate 4 is slidably connected inside the cutting table 2. The sliding plate 4 is used to adjust the horizontal position of the fixed frame 13 to accommodate workpieces of different sizes. A fixed frame 13 is fixedly connected to the top of the sliding plate 4. The fixed frame 13 is used to install positioning components to fix the workpiece. A positioning component is set inside the fixed frame 13. The positioning component is used to press the workpiece to prevent displacement during the cutting process.

[0017] Reference Figure 1 - Figure 5 The moving component includes a sliding frame 3, which is slidably connected to the top of the support frame 1. The sliding frame 3 is used to realize the linear movement of the cutting component in the X-axis direction to expand the processing range. The cutting component includes a laser unit 5 and a laser cutting head 6. The laser unit 5 is slidably connected to the side wall of the sliding frame 3. The laser unit 5 is used to generate a high-power laser beam and is adjusted through an internal optical system.

The positioning component includes a pressure plate frame 16, which is rotatably connected inside the fixed frame 13. The pressure plate frame 16 is used to apply pressure to the workpiece through rotational movement. Vertical pressure is applied to achieve fixation. A hydraulic cylinder 12 is fixedly connected inside the sliding plate 4. The hydraulic cylinder 12 is used to provide a stable linear driving force to control the movement of the positioning component.

Both the rotating rod 15 and the disc column 14 are slidably connected inside the cutting table 2 to achieve stable guidance during the movement.

[0018] Working principle: When using the laser cutting machine, calibration preparation is first performed. Pressing the pressing handle 10 compresses the spring 11, and the deformation of the spring 11 causes the ring clamp 9 to rotate inside the connecting frame 7, thereby loosening the contact between the ring clamp 9 and the X-ray lamp 8. The X-ray lamp 8 is then slidably installed onto the inner wall of the ring clamp 9. Releasing the pressing handle 10 causes the spring 11 to return to its original position, causing the ring clamp 9 to clamp the X-ray lamp 8, completing the installation and fixation of the X-ray lamp 8. Subsequently, the sliding frame 3 of the moving component slides on the top of the support frame 1, causing the laser unit 5 of the cutting component to slide on the side wall of the sliding frame 3, thereby adjusting the position of the X-ray lamp 8. The X-ray lamp 8 is used for calibration and positioning. After calibration, the sliding plate 4 is pushed to slide inside the cutting table 2, which drives the fixed frame 13 to move to adjust the distance from the object to be cut. Then, the hydraulic cylinder 12 is started to drive the disc column 14 to slide inside the cutting table 2. The disc column 14 drives the rotating rod 15 to rotate and slide inside the cutting table 2. The rotating rod 15 then drives the pressure plate frame 16 to rotate inside the fixed frame 13 and slide inside the cutting table 2, so that the pressure plate frame 16 presses the object to be cut. Finally, through the cooperation of the moving component and the cutting component, the laser instrument 5 drives the laser cutting head 6 to move and perform cutting operations on the fixed object.
