Description

Technical Field

[0001] This utility model belongs to the field of steel structure processing technology, and specifically relates to a laser cutting machine for steel structure processing. Background Technology

[0002] Laser cutting machines focus a laser beam emitted from a laser source into a high-power-density beam through an optical path system. This beam irradiates the workpiece surface, causing it to reach its melting or boiling point. Simultaneously, high-pressure gas coaxial with the beam blows away the molten or vaporized metal. In the steel structure processing field, laser cutting machines are widely used due to their high precision and efficiency. During laser cutting, the high-energy laser beam generates a large amount of heat on the steel surface. Existing laser cutting machines lack dust removal structures. If dirt or debris is present on the cut surface, the high temperature can cause difficult-to-clean spots on the cut, affecting the final quality of the steel structure. Furthermore, existing painting structures are fixed and cannot be adjusted. During processing, care must be taken to avoid interference between the painting structure and the workpiece and cutting head. Therefore, we propose a laser cutting machine for steel structure processing. Utility Model Content

[0003] In order to overcome the above-mentioned technical problems, the purpose of this utility model is to provide a laser cutting machine for steel structure processing, so as to solve the problem mentioned in the background art that the existing laser cutting machine does not have a dust removal structure. If there is dirt or debris on the surface of the cut object, the cut edge is easy to have spots that are difficult to clean due to high temperature, which affects the final quality of the steel structure. In addition, the existing painting structure is fixed and cannot be adjusted. During processing, attention needs to be paid to whether there is interference between the painting structure and the workpiece and the cutting head.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a laser cutting machine for steel structure processing, comprising a cutting machine body, a control panel fixedly connected to one side of the cutting machine body, a gantry frame mounted on the top of the cutting machine body, a laser cutting head mounted on the surface of the gantry frame, air pumps fixedly connected to both sides of the cutting machine body, a connecting pipe fixedly connected to the output end of the air pumps, fixed seats fixedly connected to both sides of the gantry frame, a fixed rod fixedly connected to the surface of the fixed seat, a rotating block rotatably connected to the surface of the fixed rod, and the top of the rotating block... The rotating block has a sliding groove, and a clamping structure is provided on its surface. The clamping structure includes a pressure plate, a pull rod is fixedly connected to one side of the pressure plate, a guide rod is fixedly connected to the other side of the pressure plate, a limit block is fixedly connected to one side of the guide rod, and a spring is sleeved on the outside of the guide rod. The top of the pressure plate has a sliding groove, and an air jet pipe is provided inside the pressure plate and the rotating block. The air jet pipe includes a locking block, a connecting part is fixedly connected to one side of the locking block, a gripping part is fixedly connected to the other side of the locking block, and a nozzle is fixedly connected to one side of the gripping part.

[0005] Preferably, both the laser cutting head and the air pump are electrically connected to the control panel.

[0006] Preferably, a first circular groove is opened on the surface of the rotating block, a rounded corner is provided on the side of the rotating block close to the first circular groove, and the rotating block is rotatably connected to the surface of the fixed rod through the first circular groove.

[0007] Preferably, four sets of second circular grooves are opened on the surface of the rotating block, the guide rod is slidably connected in the second circular grooves, and the radius of the limiting block is larger than the radius of the guide rod.

[0008] Preferably, both ends of the spring are fixedly connected to the surface of the rotating block and the surface of the limiting block respectively, and the inner side surface of the spring is not in contact with the surface of the guide rod.

[0009] Preferably, the cross-section of the engaging block is in a shape of the Chinese character "zhong", the end of the engaging block is slidably connected in the first chute and the second chute, and the cross-section of the engaging block is larger than the cross-sections of the second chute and the first chute.

[0010] Preferably, the output end of the connecting pipe is fixedly connected with the connecting part.

[0011] Compared with the prior art, the beneficial effects of the present utility model are as follows: 1. This laser cutting machine for steel structure processing is provided with a clamping structure and an air injection pipe. The air injection pipe is installed by embedding the engaging block shaped like the Chinese character "zhong" into the first chute and the second chute on the rotating block and the pressing plate. When the nozzle needs to be removed, the pressing plate is loosened only by pulling the pull rod, then the air injection pipe is gently slid along the axial direction of the first chute and the second chute, so that it can be conveniently pulled out from the first chute and the second chute to realize quick disassembly. Conversely, during installation, the engaging block only needs to be aligned with the openings of the first chute and the second chute and slid in, then the pull rod is released to rely on the spring for compression and locking. This design can complete the installation and disassembly of the nozzle without any tools. After installation, the nozzle can sweep the surfaces of the cutting machine body and the workpiece along with the movement of the gantry frame, and can also be removed for overall sweeping in a handheld manner, preventing residual sundries during laser cutting from affecting the quality of finished products.

[0012] 2. This laser cutting machine for steel structure processing is provided with a fixed base, a fixed rod and a rotating block. The rotating block can rotate on the fixed base through the cooperation of the first circular groove and the fixed rod. When sweeping is required, the nozzle is rotated above the cutting machine body, which can blow away sundries along with the movement of the gantry frame. When not in use, the nozzle can be rotated to both sides of the gantry frame, preventing interference between the clamping structure and the air injection pipe and the laser cutting head or the workpiece during processing, and improving the overall working efficiency and maintainability of the equipment.

[0015] 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.

[0016] Please see Figure 1-5 One embodiment provided by this utility model: A laser cutting machine for steel structure processing includes a cutting machine body 1. A control panel 11 is fixedly connected to one side of the cutting machine body 1. A gantry frame 12 is mounted on the top of the cutting machine body 1. A laser cutting head 13 is mounted on the surface of the gantry frame 12. Air pumps 14 are fixedly connected to both sides of the cutting machine body 1. A connecting pipe 15 is fixedly connected to the output end of the air pump 14. Fixed seats 2 are fixedly connected to both sides of the gantry frame 12. A fixed rod 21 is fixedly connected to the surface of the fixed seat 2. A rotating block 22 is rotatably connected to the surface of the fixed rod 21. A sliding groove 23 is opened on the top of the rotating block 22. A clamping structure 3 is provided on the surface of the rotating block 22. Structure 3 includes a pressure plate 31, a pull rod 32 fixedly connected to one side of the pressure plate 31, a guide rod 33 fixedly connected to the other side of the pressure plate 31, a limit block 34 fixedly connected to one side of the guide rod 33, a spring 35 sleeved on the outside of the guide rod 33, a sliding groove 36 opened on the top of the pressure plate 31, and an air jet pipe 4 is provided inside the pressure plate 31 and the rotating block 22. The air jet pipe 4 includes a locking block 42, a connecting part 41 fixedly connected to one side of the locking block 42, a gripping part 43 fixedly connected to the other side of the locking block 42, and a nozzle 44 fixedly connected to one side of the gripping part 43. A clamping structure 3 and an air jet pipe 4 are provided, and the air jet pipe 4 passes through the U-shaped locking block 42. The nozzle 44 is installed by embedding it into the sliding grooves 23 and 36 on the rotating block 22 and the pressure plate 31. When it is necessary to remove the nozzle 44, simply pull the lever 32 to loosen the pressure plate 31, and then gently slide the air jet pipe 4 along the axial direction of the sliding grooves 23 and 36 to easily pull it out of the sliding grooves 23 and 36 for quick disassembly. Conversely, during installation, simply align the locking block 42 with the opening of the sliding grooves 23 and 36 and slide it in, then release the lever 32 and rely on the spring 35 to lock it in place. This design allows for the installation and removal of the nozzle 44 without any tools. After installation, it can be used with the movement of the gantry 12 to control the cutting machine. The surface of the main body 1 and the workpiece is blown away, or it can be removed and blown away by hand to prevent debris residue from affecting the quality of the finished product during laser cutting. A fixed base 2, a fixed rod 21, and a rotating block 22 are set up. The rotating block 22 can rotate on the fixed base 2 through the cooperation of the circular groove and the fixed rod 21. When blowing is required, the nozzle 44 is rotated to the top of the cutting machine body 1, and the debris can be blown away as the gantry 12 moves. When not in use, the nozzle 44 can be rotated to both sides of the gantry 12 to prevent the clamping structure 3 and the air jet pipe 4 from interfering with the laser cutting head 13 or the workpiece during processing, thereby improving the overall working efficiency and maintainability of the equipment.

[0017] Furthermore, both the laser cutting head 13 and the air pump 14 are electrically connected to the control panel 11, which enables centralized control of the cutting process, ensuring the consistency and accuracy of processing parameters.

[0018] Further, a first circular groove is opened on the surface of the rotating block 22, a rounded corner is provided on the side of the rotating block 22 adjacent to the first circular groove, the rotating block 22 is rotatably connected to the surface of the fixed rod 21 through the first circular groove, and the rounded corner design helps reduce frictional resistance and avoid jamming when the rotating block 22 rotates 90 degrees around the fixed rod 21, ensuring smooth direction adjustment. The fixed rod 21 serves as a stable rotating shaft to provide reliable support for the rotating block 22.

[0019] Further, four sets of second circular grooves are opened on the surface of the rotating block 22, the guide rod 33 is slidably connected in the second circular grooves, and the radius of the limiting block 34 is larger than that of the guide rod 33, which ensures that the pressing plate 31 can only move towards or away from the rotating block 22 along a linear direction. The size setting of the limiting block 34 effectively prevents the guide rod 33 from completely slipping out of the second circular grooves, limits the maximum stroke range of the pressing plate 31, and ensures the working reliability of the clamping structure 3.

[0020] Further, two ends of the spring 35 are fixedly connected with the surface of the rotating block 22 and the surface of the limiting block 34 respectively, the inner surface of the spring 35 is not in contact with the surface of the guide rod 33, and the spring 35 provides continuous elastic force in a natural state or during reset. The elastic force acts on the limiting block 34 and is transmitted to the pressing plate 31 through the guide rod 33, so that the pressing plate 31 is tightly pressed against the rotating block 22, thereby forming a reliable clamping force. The inner diameter of the spring 35 is larger than the diameter of the guide rod 33, which avoids friction between the spring 35 and the guide rod 33 when the spring 35 expands and contracts, ensures smooth operation and prolongs the service life.

[0021] Further, the cross section of the engaging block 42 is in a shape of "middle", the end of the engaging block 42 is slidably connected in the first sliding groove 23 and the second sliding groove 36, the cross section of the engaging block 42 is larger than the cross sections of the second sliding groove 36 and the first sliding groove 23, the smaller end of the engaging block 42 can slide in the first sliding groove 23 and the second sliding groove 36, while the diameter of the middle part thereof is larger than the width of the first sliding groove 23 and the second sliding groove 36, so that the engaging block 42 cannot slip out in the direction perpendicular to the openings of the first sliding groove 23 and the second sliding groove 36, and must slide longitudinally along the first sliding groove 23 and the second sliding groove 36 to be installed or disassembled, thereby preventing the gas injection pipe 4 from accidentally loosening during use and ensuring its firm connection.

[0022] Further, the output end of the connecting pipe 15 is fixedly connected with the connecting portion 41, and the connecting portion 41 provides a stable interface, which ensures that the auxiliary gas delivered from the air pump 14 through the connecting pipe 15 can be reliably introduced into the gas injection pipe 4 and finally ejected directionally from the nozzle 44.

[0023] Working principle: When it is necessary to remove the nozzle 44, simply pull the lever 32 to loosen the pressure plate 31, and then gently slide the air jet pipe 4 along the axial direction of the first slide groove 23 and the second slide groove 36 to easily pull it out of the slide groove 23 and the second slide groove 36 for quick disassembly. Conversely, during installation, simply align the locking block 42 with the opening of the slide groove 23 and the second slide groove 36 and slide it in. Then release the lever 32 and rely on the spring 35 to press and lock it. Before processing, drive the gantry 12 through the control panel 11. During the movement of the gantry 12, start the air pump 14 to pump the gas from the nozzle 44 through the connecting pipe 15 to blow the surface of the cutting machine body 1 and the workpiece surface to prevent dust and other debris from affecting the process. Alternatively, the air jet pipe 4 can be removed to thoroughly blow the surface of the cutting machine body 1. Then rotate the nozzle 44 to both sides of the gantry 12 to prevent interference between the clamping structure 3 and the air jet pipe 4 and the laser cutting head 13 or the workpiece during processing.
