[0025] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below with reference to specific illustrations.

[0026] like Figures 1-4 As shown,

[0027] This embodiment provides an online laser cutting measuring instrument, including a machine base 1, a machine cover 11 installed on the outer end of the machine base 1, a worktable 2 set on the upper end of the machine base 1, and a laser emitter 3. A support plate 4 is fixedly installed on one side of the machine base 1 located on the worktable 2. The laser emitter 3 is flexibly mounted on one side of the support plate 4 via a bracket 31. A CCD camera 5 is provided on the side of the bracket 31 located on the laser emitter 3 to measure the workpiece being processed. A telescopic cover 32 for conveying cables is provided on the side of the bracket 31 away from the laser emitter 3. The laser emitter 3 and the CCD camera 5 are electrically connected to a controller 6 at the upper end of the machine base 1. A height-adjustable ring light source 7 is also installed on one side of the support plate 4. The ring light source 7 is located at the lower end of the laser emitter 3 to improve the measurement accuracy of the CCD camera 5.

[0028] In this embodiment, the support plate 4 is vertically mounted on both sides of the support plate facing the bracket 31. The two ends of the bracket 31 are slidably mounted on the first slide rail 41 by sliders. The support plate 4 is provided with an adjustment component for driving the bracket 31 to move up and down.

[0029] The adjustment assembly includes a shaft plate 42 fixedly installed at the upper and lower ends of the support plate 4 and an adjustment screw 43 rotatably installed on the shaft plate 42. An adjustment motor 44 is fixedly installed on the outer side of the shaft plate 42 at the upper end of the support plate 4. The adjustment motor 44 is connected to the adjustment screw 43 in a transmission connection. The bracket 31 is provided with a screw sleeve corresponding to the adjustment screw 43, which is threadedly connected to the adjustment screw 43 to control the lifting and lowering movement of the bracket 31.

[0030] In this embodiment, since the laser emitter 3 and CCD camera 5 are installed on the bracket 31, the overall weight of the bracket 31 is relatively heavy. If the adjustment screw 43 drives the screw sleeve to move up and down, the threads on the adjustment screw 43 and the screw sleeve are easily damaged, thereby reducing the service life of the equipment and affecting the stability of the laser emitter 3, thus affecting the processing quality.

[0031] Therefore, the upper end of the support 31 is connected to a sliding belt 8, and a counterweight 82 is connected through the sliding belt 8 to offset the weight of the support 31. The side of the support plate 4 away from the laser emitter 3 is provided with a counterweight plate 81. The upper end of the support plate 4 and the counterweight plate 81 is provided with a guide frame 83 for guiding the sliding belt 8. The counterweight 82 is slidably installed on the second slide rail at the outer end of the counterweight plate 81. The two ends of the guide frame 83 are respectively provided with guide rollers 84 for guiding the sliding belt 8.

[0032] In this embodiment, the ring light source 7 is mounted on a lifting assembly and is installed on one side of the support plate 4 via the lifting assembly. The lifting assembly includes a mounting plate 71 fixedly mounted on the support plate 4 and a lifting block 72 slidably mounted on the mounting plate 71. A lifting screw 73 is rotatably mounted on the mounting plate 71, and the upper end of the lifting screw 73 is connected to the lifting motor 74. The lifting block 72 is sleeved on the lifting screw 73, and one side of the lifting block 72 is slidably mounted on a third slide rail 75 at a corresponding position on the mounting plate 71. A lifting plate 76 is fixedly mounted on the outer end of the lifting block 72 and is fixedly connected to the ring light source 7 via the lifting plate 76. The lifting motor 74 controls the movement of the lifting block 72 via the lifting screw 73 to control the height of the ring light source 7, facilitating more accurate measurement of the processed material by the CCD camera 5.

[0033] In this embodiment, the workbench 2 includes an adjustable first plate 21 and a second plate 22. The first plate 21 is slidably mounted on the upper end of the second plate 22. A first displacement member is provided on one side of the second plate 22 to drive the first plate 21 to move vertically. The second plate 22 is slidably mounted on the upper end of the machine base 1. A second displacement member is provided on one side of the machine base 1 to drive the second plate 22 to move horizontally.

[0034] The first displacement component includes a displacement plate 23 and a displacement screw 24 rotatably mounted on the displacement plate 23, and a displacement motor 25 disposed on one side of the displacement plate 23 for driving the displacement screw 24 to rotate. A displacement sleeve is also slidably mounted on the displacement plate 23. The displacement sleeve is threadedly connected to the displacement screw 24. One side of the displacement sleeve is fixedly connected to the first plate 21 to drive the first plate 21 to move vertically.

[0035] The second displacement component has the same structure as the first displacement component.

[0036] Specifically, a CCD camera 5 is mounted on one side of the laser emitter 3, allowing for real-time online measurement of the processed material. This improves the processing accuracy of the laser emitter 3, and the integrated measurement and processing setup enhances processing efficiency and simplifies the process. A ring light source 7 is also located on one side of the support plate 4. The ring light source 7 is height-adjustable via a lifting assembly, improving the recognition accuracy of the CCD camera 5 and enhancing measurement precision. Furthermore, to prevent the heavy weight of the laser emitter 3 and CCD camera 5 on the bracket 31 from affecting the adjustment assembly's movement, a counterweight 82 is connected to the bracket 31 via a sliding belt 8. This counterweight offsets the weight of the bracket 31, improving the stability of the laser emitter 3 and CCD camera 5 during lifting and lowering.
