Description

Technical Field

[0001] This utility model relates to the field of laser cutting technology, and more specifically to a laser cutting fixture. Background Technology

[0002] Laser cutting is a precision machining technology that uses a high-power-density laser beam to irradiate materials and achieve cutting through thermal effects. The laser beam is focused onto the surface of the material, causing the local area to heat up rapidly to the melting or vaporization temperature, thereby performing cutting.

[0003] Laser cutting technology has advantages such as high precision and smooth cuts, and is widely used in sheet metal processing, automobile manufacturing, aerospace, electronics and electrical appliances and other industries. It is suitable for cutting metal sheets with relatively small thickness, such as automotive body panels, chassis guard plates and so on.

[0004] Most of the sheet metal parts suitable for laser cutting in the aforementioned automotive manufacturing industry are not smooth and flat, but rather roughly plate-shaped with some uneven areas. When laser cutting these sheet metal parts, they need to be placed on a mold that corresponds to their shape. The protruding parts of the mold are embedded into the recesses of the sheet metal to stabilize the sheet metal for cutting.

[0005] However, in actual operation, different shaped plates require different shaped molds for support. This not only requires the preparation of multiple support molds, but also necessitates frequent mold changes, which reduces cutting efficiency. Utility Model Content

[0006] To overcome the aforementioned deficiencies of the prior art, this utility model provides a laser cutting fixture. By setting multiple support components, the matrix-arranged support components form a whole. The shape of this whole can be freely changed according to the shape of different plates, making it widely applicable. It eliminates the need for multiple molds, reducing costs, and also eliminates the need for frequent mold replacements, thus improving cutting efficiency.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a laser cutting fixture, including a base, a cutting mechanism on the top of the base, a mounting frame on the top of the base, the mounting frame being shaped like a "Z", and multiple sets of support components for supporting the plate to be cut being provided on the mounting frame, the support components being arranged in a matrix on the mounting frame; The support assembly includes a threaded rod that passes through the mounting frame. The threaded rod is threadedly connected to the mounting frame. A top rod is fixedly provided at the top of the threaded rod, and the top of the top rod contacts the plate. A hexagonal screw head is fixedly provided at the bottom of the threaded rod. A pad is fixedly provided at the top of the base, and one end of the mounting bracket is movably connected to the pad via a hinge, which allows the mounting bracket to be lifted upwards to facilitate adjustment of the height of the support components.

[0008] Furthermore, the top of the pad is provided with a groove, the mounting bracket is mounted in the groove of the pad, and two limiting plates are provided at the joint between the other end of the mounting bracket and the pad, with one end of the limiting plate rotatably connected to the top of the pad.

[0009] Furthermore, the cutting mechanism includes a movable seat, which is slidably connected to the top of the base via a slide rail. The movable seat is located on one side of the mounting frame, and a robotic arm is provided at the top of the movable seat. A laser is provided at one end of the robotic arm.

[0010] Furthermore, the top of the movable seat is bolted with a vertical plate, and the top of the movable seat is provided with a connecting arm. Both ends of the connecting arm are fixed with end rods, one of which is rotatably connected to one side of the vertical plate, and the two end rods are of different lengths.

[0011] Furthermore, the front side of the mounting bracket is provided with an eye protection panel that can be rotated to lie flat, and the other end rod is rotatably connected to one side of the eye protection panel.

[0012] Furthermore, a protruding plate is fixedly provided at the bottom end of the goggle, and a fixed bracket is provided at the top end of the base. The bottom end of the protruding plate extends into the interior of the fixed bracket, and both sides of the protruding plate are rotatably connected to the inner wall of the fixed bracket. A spring is provided on both sides of the protruding plate, and the two ends of the spring are fixedly connected to the inner wall of the fixed bracket and the protruding plate, respectively.

[0013] The technical effects and advantages of this utility model are as follows: This utility model sets multiple support components on the mounting frame. The matrix-arranged support components form a whole. Rotating the support components allows the whole support components to move up and down relative to the mounting frame, adjusting the shape of the whole formed by the support components. This shape can be freely changed according to the shape of different plates, with a wide range of applications. It eliminates the need for multiple molds, reducing costs and eliminating the need for frequent mold changes, thus improving cutting efficiency. When changing plates, the safety guard can be rotated forward to flatten it, preventing it from obstructing the plate. This also allows the connecting arm to move forward, pulling the robotic arm and laser forward. This prevents the robotic arm and laser from blocking the plate and interfering with the plate change, further improving cutting efficiency. Attached Figure Description

Detailed Implementation

[0016] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0017] Refer to the instruction manual appendix Figures 1-6 This utility model provides a laser cutting fixture, including a base 1, a cutting mechanism on the top of the base 1, and a mounting frame 6 on the top of the base 1. The mounting frame 6 is shaped like a "Z". The mounting frame 6 is provided with multiple sets of support components 5 for supporting the plate to be cut. The support components 5 are arranged in a matrix on the mounting frame 6. The support assembly 5 includes a threaded rod 501 that passes through the mounting frame 6. The threaded rod 501 is threadedly connected to the mounting frame 6. A top rod 502 is fixedly provided at the top end of the threaded rod 501. The top end of the top rod 502 contacts the plate. A hexagonal screw head 503 is fixedly provided at the bottom end of the threaded rod 501. The matrix-arranged support components 5 form a whole. In the initial state, all the top rods 502 are at the same height. The top of the whole is flat, and the outline of the whole is cubic. Rotating the hexagonal screw head 503 can drive the threaded rod 501 to rotate. Under the action of the thread, the threaded rod 501 can move up and down relative to the mounting frame 6 to adjust the height of the top rods 502. Therefore, according to the shape of the plate to be cut, the support components 5 of the corresponding parts can be adjusted so that the parts are either raised or recessed, thereby changing the whole from the initial state. After the change, the outline of the whole can match the shape of the plate. When the plate is placed on the top of the mounting frame 6, the whole composed of the support components 5 can fit into the plate like a mold, so that the plate is placed stably for subsequent cutting work. This method adjusts the overall shape of the support components 5 by adjusting the up and down movement of individual support components 5. This shape can be freely changed according to the shape of different plates, making it widely applicable. It eliminates the need for multiple molds, reducing costs, and also eliminates the need for frequent mold changes, thus improving cutting efficiency.

[0018] The cutting mechanism includes a movable seat 301, which is slidably connected to the top of the base 1 via a slide rail. The movable seat 301 is located on one side of the mounting frame 6. A mechanical arm 3 is provided at the top of the movable seat 301, and a laser 4 is provided at one end of the mechanical arm 3.

[0019] The sliding seat 301 can drive the robotic arm 3 and the laser 4 to move and adjust their positions. During the cutting process, the robotic arm 3 is controlled by a pre-set program to drive the laser 4 to move along a set path. The laser 4 emits a high-temperature laser beam during the movement. The laser beam irradiates the placed plate and melts the material to form a cut, thereby achieving the cutting of the plate. Laser cutting using the robotic arm 3 and the laser 4 is a mature existing technology and will not be described in detail here.

[0020] To facilitate adjustment of support component 5, such as Figure 4 , Figure 5 As shown, a pad 7 is fixedly provided at the top of the base 1, and one end of the mounting bracket 6 is movably connected to the pad 7 via a hinge, which allows the mounting bracket 6 to be lifted upwards to facilitate adjustment of the height of the support component 5.

[0021] The top of the pad 7 has a groove, and the mounting bracket 6 is located in the groove of the pad 7. Two limiting plates 701 are provided at the joint between the other end of the mounting bracket 6 and the pad 7. One end of the limiting plate 701 is rotatably connected to the top of the pad 7.

[0022] During normal use, the mounting bracket 6 remains horizontal. The limiting plate 701 rests on the joint between the other end of the mounting bracket 6 and the pad 7, preventing the mounting bracket 6 from being lifted downwards and keeping it stable. When it is necessary to adjust the support component 5, rotate the limiting plate 701 so that one end of the limiting plate 701 is removed from the mounting bracket 6, releasing the fixing of the mounting bracket 6. Then lift the mounting bracket 6 upwards. Under the action of the hinge, the mounting bracket 6 and the support component 5 are lifted up, exposing the hexagonal screw head 503 located below the mounting bracket 6, making it easy to rotate the hexagonal screw head 503, and thus making it easy to adjust the support component 5.

[0023] During laser cutting, it is necessary to avoid laser damage to the operator's eyes, such as... Figure 1 , Figure 3As shown, the front side of the mounting bracket 6 is provided with an eye protection plate 2, which can be rotated and laid flat. A protruding plate 201 is fixedly provided at the bottom end of the eye protection plate 2. A fixed bracket 202 is provided at the top end of the base 1. The bottom end of the protruding plate 201 extends into the interior of the fixed bracket 202. Both sides of the protruding plate 201 are rotatably connected to the inner wall of the fixed bracket 202. Both sides of the protruding plate 201 are provided with a spring 203. The two ends of the spring 203 are fixedly connected to the inner wall of the fixed bracket 202 and the protruding plate 201, respectively.

[0024] During the cutting process, the protective goggle 2 remains vertical, standing in front of the mounting frame 6. The protective goggle 2 is semi-transparent, and the intensity of the laser light is greatly reduced after passing through it, making it easier for personnel to observe the cutting process while preventing strong light from causing magnetic force on the eyes. The principle of the protective goggle 2 is the same as that of existing protective goggles, so it will not be described in detail here. After the cutting is completed, the cut plate needs to be removed and replaced with a new one. At this time, the protective goggle 2 can be rotated forward to flatten it and no longer obstruct the mounting frame 6, making it easier for personnel to replace the plate. When the protective goggle 2 rotates forward, it drives the convex plate 201 to rotate inside the fixed bracket 202, causing the spring 203 to tighten. After the operation is completed, the protective goggle 2 is released, and the elasticity of the spring 203 is released, which drives the convex plate 201 to rotate back, thereby driving the protective goggle 2 back to its original position.

[0025] As the goggle guard 2 rotates, the cutting mechanism moves accordingly. Figure 1 , Figure 4 As shown, the top of the movable seat 301 is provided with a vertical plate 802 by bolts, and the top of the movable seat 301 is provided with a connecting arm 8. Both ends of the connecting arm 8 are fixedly provided with end rods 801. One end rod 801 is rotatably connected to one side of the vertical plate 802. The two end rods 801 are of different lengths, and the other end rod 801 is rotatably connected to one side of the goggle plate 2.

[0026] During normal cutting operations, the protective goggle 2 blocks the front of the mounting frame 6. Therefore, when it is necessary to replace the plate, the protective goggle 2 must be laid flat. Similarly, during cutting, the robotic arm 3 and laser 4 are mounted above the plate. After cutting, when replacing the plate, the robotic arm 3 and laser 4 will also obstruct the view, making replacement inconvenient. Therefore, when the protective goggle 2 is rotated to lay flat, the protective goggle 2 will pull the end rod 801 and the connecting arm 8, and the connecting arm 8 will pull the upright plate 802. The upright plate 802 is fixed on the moving seat 301. Therefore, the moving seat 301 will be pulled forward as the protective goggle 2 is laid flat. The moving seat 301 slides and moves the robotic arm 3 and laser 4 forward, removing them from above the plate, making it easier to replace the cut plate. When the protective goggle 2 returns to its original position under the action of elasticity, it will also push the moving seat 301 backward through the connecting arm 8, thereby allowing the robotic arm 3 and laser 4 to return to their original positions.

[0027] Finally: The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
