Description

Technical Field

[0001] This utility model relates to the field of positioning tooling technology, specifically to a positioning tooling for a laser cutting machine for irregularly shaped plates. Background Technology

[0002] Irregularly shaped sheets are custom-made sheets of non-standard size or shape. Their shape, size, and thickness differ from those of conventional sheets. They are usually customized according to specific usage requirements. During the processing of irregularly shaped sheets, cutting equipment, such as laser cutting machines, is required to cut the sheets according to the preset shape and size. This can achieve high-precision irregular cutting and is commonly used in fields such as construction, automobile manufacturing, furniture manufacturing, and aerospace.

[0003] Currently, when laser cutting machines cut irregularly shaped sheets, they use a high-energy-density laser beam to irradiate the sheet, causing it to melt or vaporize instantly. The molten or vaporized material is then blown away by an auxiliary gas. During the cutting process, in order to improve the stability of the cutting, fixtures or positioning devices are needed to fix the irregularly shaped sheet in place to prevent it from moving during the cutting process. However, the positioning range of the positioning fixtures currently used for irregularly shaped sheets is fixed, making it inconvenient to adjust the position of the irregularly shaped sheet according to the cutting requirements of the laser cutting machine, which can easily reduce the cutting effect of the irregularly shaped sheet.

[0047] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0048] Please see Figures 1 to 5 A positioning fixture for a laser cutting machine for irregularly shaped sheet metal includes a cutting table 1, a support base, a positioning bracket 2, positioning components, a fixed frame 3, an adjusting frame 4, and a moving column 5. The support base is located at the bottom of the cutting table 1, and the positioning bracket 2 is located at the top of the cutting table 1. The positioning bracket 2 has multiple positioning slots. Multiple positioning components are provided, and each positioning component is detachably installed in one of the multiple positioning slots. The fixed frame 3 is detachably connected to the bottom of the cutting table 1. The adjusting frame 4 is movably mounted on the fixed frame 3 via an adjusting base. The moving column 5 is movably mounted on the adjusting frame 4 via a moving component, and the moving column 5 is fixedly connected to the positioning bracket 2. The cutting table 1 has multiple transverse tracks and multiple longitudinal tracks, which allow the moving column 5 to move laterally or longitudinally on the cutting table 1, thereby adjusting the position of the positioning bracket 2.

[0049] refer to Figure 1 as well as Figure 3The positioning assembly includes a positioning slide plate 6, a positioning cone 7, a positioning strip 8, a connecting rod 9, a compression spring 10, and a connecting post 11. The positioning slide plate 6 is detachably installed in the positioning groove and slides within the positioning groove. The positioning cone 7 is connected through the positioning slide plate 6. The positioning groove has multiple positioning holes that match the positioning cone 7. The positioning strip 8 is fixedly connected to the top of the positioning cone 7. There are two connecting rods 9, which are symmetrically connected to the bottom of the positioning strip 8. The compression spring 10 is fixedly connected to the bottom of each connecting rod 9. The connecting post 11 is fixedly connected between each compression spring 10 and the positioning slide plate 6. When the positioning slide plate 6 needs to slide, force is applied to the positioning strip 8, causing the positioning strip 8 to move the positioning cone 7 upward. When the positioning cone 7 does not obstruct the sliding of the positioning slide plate 6, the positioning slide plate 6 is slid. When the positioning slide plate 6 slides to the appropriate position, the positioning strip 8 is released. At this time, the two compression springs 10 will retract accordingly, causing the positioning cone 7 to move towards each other, so that the positioning cone 7 can be inserted into the corresponding positioning hole.

[0050] When positioning irregularly shaped sheets of different specifications is required, the number of positioning slide plates 6 is rotated according to the specifications of the irregularly shaped sheet, and the multiple positioning slide plates 6 are installed and slid in multiple positioning slots. The multiple positioning slide plates 6 are moved to appropriate positions. When the multiple positioning slide plates 6 abut against multiple positions of the irregularly shaped sheet, the positioning cones 7 are inserted into the corresponding multiple positioning holes to fix the positions of the multiple positioning slide plates 6. This allows the multiple positioning slide plates 6 to stably limit the irregularly shaped sheet, improving the stability of laser cutting of irregularly shaped sheets.

[0051] refer to Figure 4 as well as Figure 5 The moving component includes a motor 12, a threaded rod 13, and a limiting rod 14. The motor 12 is mounted on one side of the adjusting frame 4 via a mounting bracket. The motor 12 is set to automatically perform forward and reverse rotation. The threaded rod 13 is rotatably mounted inside the adjusting frame 4, and a drive rod is fixedly connected between the threaded rod 13 and the output end of the motor 12. The threaded rod 13 is threadedly connected to the moving column 5. The limiting rod 14 is fixedly connected to one side of the threaded rod 13. The adjusting frame 4 has a limiting groove for the limiting rod 14 to rotate, which helps to increase the stability of the rotation of the limiting rod 14 and the threaded rod 13. Two moving blocks 22 are symmetrically connected on the moving column 5. The adjusting frame 4 has a moving groove for the moving blocks 22 to slide. When the moving column 5 moves inside the adjusting frame 4, the two moving blocks 22 will also move in the two moving grooves respectively, thereby limiting the movement of the moving column 5 and allowing the moving column 5 to drive the positioning bracket 2 to move smoothly.

[0052] Starting the motor 12 causes the drive rod and threaded rod 13 to rotate, which allows the moving column 5 to move within the corresponding longitudinal track, thereby adjusting the laser cutting position of the positioning bracket 2 and the irregular plate.

[0053] refer to Figure 4 as well as Figure 5 The adjusting seat includes an electric cylinder 15 and an adjusting slider 16. The electric cylinder 15 is installed in the fixed frame 3, and the output end of the electric cylinder 15 is fixedly connected to the adjusting frame 4. The adjusting slider 16 is fixedly connected to the bottom end of the adjusting frame 4. The fixed frame 3 is provided with an adjusting groove for the adjusting slider 16 to slide. The adjusting slider 16 slides in the adjusting groove, which can limit the sliding of the adjusting frame 4 in the fixed frame 3 and improve the stability of the adjusting frame 4 sliding in the fixed frame 3.

[0054] When the electric cylinder 15 is started, the adjusting frame 4 slides within the fixed frame 3, which allows the moving column 5 to move within the corresponding transverse track. This allows for adjustment of the transverse position of the positioning bracket 2 and the irregularly shaped sheet material, facilitating laser cutting at different positions of the irregularly shaped sheet material.

[0055] refer to Figure 1 as well as Figure 2 A fixing seat is provided between the fixing frame 3 and the cutting table 1. The fixing seat includes a fixing plate 17, a fixing screw 18 and a fixing ring 19. Multiple fixing plates 17 are provided, and multiple fixing plates 17 are fixedly connected to the fixing frame 3. The fixing screw 18 is threaded between each fixing plate 17 and the cutting table 1, and the fixing ring 19 is threaded on each fixing screw 18.

[0056] By tightening multiple fixing screws 18 between multiple fixing plates 17 and the cutting table 1, the cutting table 1 and the multiple fixing plates 17 can be connected. At the same time, by tightening multiple fixing rings 19 on the multiple fixing screws 18, the stability of the connection between the cutting table 1 and the multiple fixing plates 17 can be increased. This allows for the stable installation and disassembly of the fixing frame 3 on the cutting table 1, and facilitates the installation, disassembly and replacement of the adjusting frame 4 and the motor 12.

[0057] refer to Figure 1 The support base includes a support frame 20 and a support base 21. Multiple support frames 20 are provided, and multiple support frames 20 are fixedly connected to the bottom end of the cutting table 1. The support base 21 is fixedly connected to the bottom end of each support frame 20.

[0058] Multiple support blocks 21 can stably support multiple support frames 20 on the ground, thereby enabling multiple support frames 20 to stably support the cutting table 1, positioning bracket 2 and irregular sheet material, improving the stability when laser cutting irregular sheet material.

[0059] In summary, the irregularly shaped sheet material to be cut is first placed on the positioning bracket 2. Multiple positioning slide plates 6 are selected according to the specifications of the sheet material, and each slide plate 6 slides within a positioning groove, causing it to abut against multiple sides of the sheet material. Multiple positioning cones 7 then enter multiple positioning holes, providing stable positioning of the sheet material on the positioning bracket 2. Next, according to the laser cutting requirements, the electric cylinder 15 is activated, causing the adjusting frame 4 to slide on the fixed frame 3. Simultaneously, the moving column 5 drives the positioning bracket 2 and the sheet material to slide accordingly. The motor 12 is then activated, causing the moving column 5 to move within the adjusting frame 4 via the rotation of the threaded rod 13. This facilitates the movement of the positioning bracket 2 and the sheet material, allowing for adjustment of the laser cutting position of the sheet material and thus improving the laser cutting effect.
