Description

Technical Field

[0001] The utility model relates to the technical field of laser cutting, in particular to a positioning device for laser cutting which is easy to adjust. Background Art

[0002] With the development of modern manufacturing industry, laser cutting technology has become an indispensable part of industrial production due to its high precision, high efficiency and wide processing applicability. Especially in the fields of precision processing, complex pattern cutting and thin plate processing, laser cutting has shown unparalleled advantages.

[0003] At present, the positioning device of the laser cutting machine mainly relies on the recognition and positioning of the edge of the workpiece to achieve precise control of the cutting path. This method can achieve better cutting results when processing thick plates or workpieces with simple structures. However, when facing thinner plate processing, this positioning method exposes obvious limitations.

[0004] Thinner plates are easily affected by external factors such as thermal expansion, mechanical stress or lifting, causing warping and deformation. Traditional positioning systems can only position the edges of plates and cannot detect and adjust the position deviation caused by plate warping, resulting in reduced cutting accuracy.

[0005] In addition, the warped sheet metal is prone to overheating under the action of the laser beam, further aggravating the deformation, affecting the cutting quality, and even causing material damage.

[0006] Therefore, those skilled in the art have proposed a positioning device that is easy to adjust for laser cutting. Utility Model Content

[0007] In view of the above problems existing in the prior art, the main purpose of the utility model is to provide an easily adjustable positioning device for laser cutting.

[0008] The technical solution of the utility model is as follows: a positioning device that is easy to adjust for laser cutting, including a placement plate, both sides of the placement plate are provided with slide grooves, the interior of the slide grooves are symmetrically and slidably connected with two limit blocks, one end of the limit blocks extends to the outside of the slide grooves, the tops of the slide grooves are fixedly connected with vertical rods, and horizontal rods are fixedly connected between the corresponding two vertical rods, the interiors of the limit blocks are symmetrically threaded with two first fastening screws, and one end of the first fastening screws conflicts with the inner wall of the slide groove.

[0009] Through the above technical means, the limit block can slide inside the slide slot, and the vertical rod and the cross rod can be driven to move by controlling the position of the slide slot. The position can be adjusted according to the length of different plates through the movement of the cross rod.

[0010] As a preferred embodiment, a slot is provided inside the cross bar, and the slot is in a gourd-shaped structure. The inside of the slot is symmetrically and movably connected with a fixing sleeve, and the outside of the fixing sleeve and below the cross bar are threadedly connected with a fixing nut.

[0011] Through the above technical means, the fixing sleeve can be placed in the corresponding slot, and through such a setting, it can be adjusted according to different plate widths.

[0012] As a preferred embodiment, the interior of the fixing sleeve is threadedly connected with an adjusting screw rod, and the bottom of the adjusting screw rod extends to the bottom of the fixing sleeve and is rotatably connected with a turntable.

[0013] Through the above technical means, by rotating the adjusting screw rod, the turntable is driven to descend, and then it contacts the plate, so that the raised part of the plate can be flattened.

[0014] As a preferred embodiment, the four top corners of the placement plate are fixedly connected with fixed plates, a connecting rod is fixedly connected between two corresponding fixed plates, and a limiting plate is slidably connected between the outer sides of the two connecting rods.

[0015] Through the above technical means, the limit plate can slide on the outside of the connecting rod, and the limit plate is combined with one side of the plate, so as to ensure that one side of the plate is set parallel to the running track of the laser cutting.

[0016] As a preferred implementation, the internal thread of the limiting plate is connected with a second fastening screw, and one end of the second fastening screw is in conflict with the connecting rod.

[0017] Through the above technical means, the limiting plate can be fixed by the second fastening screw.

[0018] Compared with the prior art, the advantages and positive effects of the utility model are:

[0019] The utility model ensures that the plate and the laser cutting machine remain parallel by pushing the limit plate. Then, the turntable is lowered to fit closely with the plate, effectively flattening the raised part of the plate. This ensures that the plate always remains flat and parallel during the cutting process. Compared with traditional positioning devices, this device not only improves the cutting accuracy, but also effectively avoids the problem of plate deformation caused by heat, thereby significantly improving the processing quality and efficiency.

[0028] like Figure 1-Figure 4 As shown, the utility model provides a positioning device for laser cutting that is easy to adjust: it includes a placement plate 1, both sides of the placement plate 1 are provided with a slide groove 2, the interior of the slide groove 2 is symmetrically slidably connected with two limit blocks 3, one end of the limit blocks 3 extends to the outside of the slide groove 2, the top of the slide groove 2 is fixedly connected with a vertical rod 4, and a horizontal rod 6 is fixedly connected between the two corresponding vertical rods 4, the interior of the limit block 3 is symmetrically threaded with two first fastening screws 5, and one end of the first fastening screw 5 conflicts with the inner wall of the slide groove 2;

[0029] In summary: the limit block 3 can slide inside the slide groove 2, and the vertical rod 4 and the cross rod 6 can be driven to move by controlling the position of the slide groove 2. The position can be adjusted according to different plate lengths through the movement of the cross rod 6.

[0030] like Figure 1-Figure 4 As shown, a slot 7 is provided inside the cross bar 6, and the slot 7 is a gourd-shaped structure. A fixing sleeve 8 is symmetrically and movably connected inside the slot 7, and a fixing nut 9 is threadedly connected to the outside of the fixing sleeve 8 and located below the cross bar 6;

[0031] In summary: the fixing sleeve 8 can be placed in the corresponding slot 7. By setting it in this way, it can be adjusted according to different plate widths.

[0033] In summary: by rotating the adjusting screw rod 10, the turntable 11 is driven to descend and then come into contact with the plate, so that the raised part of the plate can be flattened.

[0034] like Figure 1-Figure 4 As shown, the four corners of the top of the placement plate 1 are fixedly connected with fixed plates 12, and a connecting rod 13 is fixedly connected between two corresponding fixed plates 12, and a limiting plate 14 is slidably connected between the outer sides of the two connecting rods 13;
