[0020] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0021] See also Figures 1 to 4 The utility model provides a technical solution: a size-adjustable square shaping laser processing device, comprising a work frame 1, a mounting frame 4 is mounted on the work frame 1, a light source 5 is fixed on the lower side of the mounting frame 4, a laser shaper 6 is fixed on the lower side of the light source 5, a focuser 7 is fixed on the lower side of the laser shaper 6, two sliding blocks 8 are slidably engaged on the work frame 1, a placement plate 9 is rotatably engaged between the two sliding blocks 8, an exhaust structure is mounted on the placement plate 9, and a clamping structure is mounted on the placement plate 9.

[0022] In this embodiment, a first rodless electric cylinder 2 is fixed to the workbench 1. The output end of the first rodless electric cylinder 2 is fixedly connected to the mounting frame 4. The laser shaper 6 has the same structure as a laser shaping device disclosed in Patent Publication No. CN214849531U. The focuser 7 has the same structure as a square laser spot focuser disclosed in Patent Publication No. CN87202331U.

[0023] The mounting frame 4 can be driven to slide by the first rodless electric cylinder 2 , thereby driving the light source 5 , the laser shaper 6 and the focuser 7 to move, thereby changing the laser processing position.

[0024] Two second rodless electric cylinders 3 are fixed on the workbench 1, and the output end of the second rodless electric cylinder 3 is fixedly connected to the sliding block 8. Rotating shafts 10 are fixed on both sides of the placement plate 9, and the rotating shaft 10 is rotatably connected to the sliding block 8. One end of the rotating shaft 10 is threadedly fitted with a fixing nut 11. The clamping structure includes two clamping plates 12, and a sliding rod 15 is fixed to one side of the clamping plate 12. A positioning shaft 14 is fixed on the placement plate 9, and the positioning shaft 14 corresponds to the sliding rod 15. A sliding groove 13 is opened in the sliding rod 15, and the sliding groove 13 corresponds to the positioning shaft 14. The end of the positioning shaft 14 is threadedly fitted with a positioning nut.

[0025] Specifically, the sliding block 8 can be driven to slide by the second rodless electric cylinder 3, thereby driving the placement plate 9 to slide. When the angle of the placement plate 9 needs to be adjusted, the fixing nut 11 can be loosened to rotate the placement plate 9. The placement plate 9 rotates between the two sliding blocks 8 through the rotating shaft 10. When it is rotated to a certain angle, the fixing nut 11 is rotated to fix the placement plate 9.

[0026] Place the workpiece on the placement plate 9, then slide the clamping plate 12, and the positioning shaft 14 slides in the slide groove 13, so that the two clamping plates 12 clamp the workpiece, and then rotate the positioning nut to clamp the slide rod 15, thereby fixing the clamping plate 12.

[0028] Specifically, the placement plate 9 is larger, and the through hole 16 located on the side will not be blocked by the workpiece. The through hole 16 located on the lower side of the workpiece can fix the workpiece by negative pressure adsorption. When laser processing is performed, the exhaust fan 18 is started to exhaust air, which can extract the smoke generated during processing, thereby preventing the smoke from affecting the laser processing.
