Description

Technical Field

[0001] This utility model relates to the field of laser cutting machine technology, and more specifically, to a laser cutting machine that is easy to adjust. Background Technology

[0002] As one of the core processes in modern industrial processing, laser cutting technology has been widely used in the cutting of metal and non-metal materials due to its advantages such as high cutting precision, high efficiency, and small heat-affected zone. However, as the market demands for the diversity, complexity, and precision of processed parts, existing laser cutting machines have gradually revealed many technical defects that are incompatible with production needs in practical applications.

[0003] First, the fixed height of the worktable in existing laser cutting machines makes it difficult to control stably according to different production needs, which is not suitable for mass production scenarios, affects cutting accuracy, and seriously restricts production efficiency.

[0004] Secondly, most existing laser cutting machines use a clamping structure with manual clamping on one side or independent adjustment on both sides. Operators need to adjust the clamping components on both sides separately, which is not only cumbersome, but also prone to causing the workpiece to shift or tilt due to asynchronous adjustment on both sides. At the same time, for workpieces of different thicknesses, insufficient clamping force can easily cause the workpiece to shake during the cutting process, making it difficult to meet diverse processing needs.

[0005] In addition, during the laser cutting process, the material is heated and produces a large amount of harmful fumes. If not dealt with in time, it will not only pollute the working environment and endanger the health of operators, but also adhere to the laser cutting head lens and equipment surface, affecting laser emission efficiency and equipment lifespan. Utility Model Content

[0006] (a) Technical problems to be solved In view of the problems existing in the prior art, this utility model provides a laser cutting machine that is easy to adjust, so as to solve the technical problem mentioned in the background art that it is difficult to stably control the height and clamping force according to different production needs.

[0007] (II) Technical Solution To achieve the above objectives, this utility model provides the following technical solution: A conveniently adjustable laser cutting machine includes a processing plate. A movable support frame is provided on the side wall of the processing plate, and a movable laser cutting head is provided on the support frame. A groove is provided at the center of the processing plate, and a through-type bidirectional threaded rod is provided in the groove. Symmetrical clamping blocks are provided on the bidirectional threaded rod, and the clamping blocks are in contact with and slidably connected to the groove. A first motor is provided on one side of the processing plate, and one end of the bidirectional threaded rod is connected to the output end of the first motor. A connecting frame is provided on the upper end of the clamping blocks, and an electric push rod is provided on one side of the connecting frame. A pressing plate is provided at the lower end of the electric push rod. A height adjustment component is provided at the lower end of the processing plate, and a smoke filter component is provided at one end of the laser cutting head.

[0008] The present invention is further configured such that the height adjustment assembly includes a base plate, a fixed rod, a screw, an adjusting rod, and a second motor. The fixed rod is located on the side wall of the base plate, the screw passes through the fixed rod, the adjusting rod is on the screw and threadedly connected to it, and the adjusting rod is slidably connected to the fixed rod. The second motor is located on the bottom wall of the base plate, the fixed rod passes through the base plate and is connected to the output end of the second motor, and symmetrical limiting components are provided on both sides of the side wall of the base plate to realize the height adjustment of the processing plate and ensure stable lifting.

[0009] The present invention is further configured such that the smoke filtering assembly includes a filter tube, an exhaust fan, and filter cotton. The filter tube is located on one side of the laser cutting head, the exhaust fan is located at the upper end of the filter tube, and the filter cotton penetrates the filter tube, which can promptly draw in the smoke generated during cutting. The filter cotton can filter harmful substances.

[0010] The present invention is further configured such that the limiting component includes a sliding rod and a lifting rod. The sliding rod is symmetrically arranged at both ends of the side wall of the base plate, and the lifting rod passes through the sliding rod and is slidably connected to it. The upper end of the lifting rod is connected to the processing plate, and plays a guiding and limiting role when the processing plate is raised and lowered, so as to prevent the processing plate from tilting.

[0011] The present invention is further provided with support feet at the four corners of the bottom wall of the base plate to enhance the overall stability of the equipment and prevent the equipment from shifting due to vibration during the cutting process.

[0012] The present invention is further provided with an anti-slip pad on the bottom wall of the pressing plate. The anti-slip pad is made of high-temperature resistant silicone material and has anti-slip texture on its surface, which can increase the friction with the workpiece and prevent the workpiece from sliding when pressing.

[0013] The present invention is further configured such that a horn-shaped air intake is provided at the lower end of the filter tube, and the air intake faces the cutting area of ​​the laser cutting head, thereby expanding the smoke absorption range and enabling more precise smoke capture when facing the cutting area.

[0014] (III) Beneficial Effects Compared with the prior art, this utility model provides a laser cutting machine that is easy to adjust, and has the following beneficial effects: 1. In the workpiece fixing and positioning stage, the device adopts a structure of bidirectional threaded rod and symmetrical clamping blocks, coupled with the first motor drive, to realize the automated synchronous clamping of workpieces. It can quickly and accurately position workpieces of different sizes in the center of the processing plate, avoiding workpiece offset or tilting caused by manual adjustment of the clamping blocks on both sides. The electric push rod on the connecting frame, together with the pressing plate, can assist in fixing the workpiece from the vertical direction. It is especially suitable for thin and easily deformable processing materials, which significantly improves the reliability of workpiece fixing and lays the foundation for precise cutting.

[0015] 2. The second motor drives the screw to rotate, which in turn drives the adjusting rod, which is threadedly connected to the screw, to slide along the fixed rod, thereby pushing the processing plate up and down. No manual adjustment is required. The sliding cooperation between the fixed rod and the adjusting rod provides a stable guide for the lifting and lowering of the processing plate, avoiding deviation during the lifting and lowering process, ensuring that the processing plate always remains in a horizontal state, and greatly improving the adaptability of the equipment to diverse processing needs.

[0016] 3. The filter tube is located near the laser cutting head. Together with the exhaust fan, it can promptly draw in the fumes generated during cutting. The filter cotton can filter out harmful substances and reduce the impact of fumes on the environment, human body, and equipment. Attached Figure Description

[0022] Please see Figure 1-5 A laser cutting machine with easy adjustment includes a processing plate 1. A movable support frame 2 is provided on the upper side wall of the processing plate 1. A movable laser cutting head 3 is provided on the support frame 2. A groove is provided at the center of the processing plate 1. A through-hole bidirectional threaded rod 4 is provided in the groove. Symmetrical clamping blocks 5 are provided on the bidirectional threaded rod 4. The clamping blocks 5 fit and slide with the groove. A first motor 6 is provided on one side of the processing plate 1. One end of the bidirectional threaded rod 4 is connected to the output end of the first motor 6. A connecting frame 7 is provided on the upper end of the clamping blocks 5. An electric push rod 8 is provided on one side of the connecting frame 7. A pressing plate 9 is provided at the lower end of the electric push rod 8. A height adjustment component is provided at the lower end of the processing plate 1. A smoke filter component is provided at one end of the laser cutting head 3.

[0023] The height adjustment assembly includes a base plate 10, a fixing rod 11, a screw 12, an adjusting rod 13, and a second motor 14. The fixing rod 11 is located on the upper side wall of the base plate 10, the screw 12 passes through the fixing rod 11, the adjusting rod 13 is on the screw 12 and threadedly connected to it, and the adjusting rod 13 is slidably connected to the fixing rod 11. The second motor 14 is located on the bottom wall of the base plate 10, the fixing rod 11 passes through the base plate 10 and is connected to the output end of the second motor 14, and symmetrical limiting components are provided on both sides of the upper side wall of the base plate 10.

[0024] The limiting assembly includes a sliding rod 18 and a lifting rod 19. The sliding rod 18 is symmetrically arranged at both ends of the upper side wall of the base plate 10. The lifting rod 19 passes through the sliding rod 18 and is slidably connected to it. The upper end of the lifting rod 19 is connected to the processing plate 1.

[0025] In this embodiment, the operator places the workpiece to be processed on the processing plate 1, aligns it roughly with the center of the processing plate 1, and then starts the first motor 6. The first motor 6 drives the bidirectional threaded rod 4 to rotate. Since the threads on both sides of the bidirectional threaded rod 4 are opposite, the two symmetrical clamping blocks 5 connected to it will move towards each other along the groove, gradually approaching and clamping the two sides of the workpiece, thus achieving the initial fixation of the workpiece in the horizontal direction. After the horizontal clamping is stable, the electric push rod 8 on the connecting frame 7 is started, pushing the lower pressing plate 9 to descend vertically until the pressing plate 9 is tightly attached to the upper surface of the workpiece, thus fixing the workpiece in the vertical direction for the second time, avoiding displacement or warping of the workpiece during the cutting process, and ensuring that the workpiece remains stable during the processing.

[0026] More specifically, the height of the processing plate 1 can be adjusted by the height adjustment component according to the cutting requirements. After the second motor 14 is started, the output end of the second motor 14 drives the screw 12 to rotate. The adjusting rod 13, which is threaded to the screw 12, rises and falls vertically under the guidance of the fixed rod 11, thereby pushing the processing plate 1 to rise and fall synchronously. During this process, the lifting rod 19 slides along the inner wall of the sliding rod 18, constraining the lifting trajectory of the processing plate 1 and preventing it from tilting, ensuring that the processing plate 1 always remains horizontal. After the workpiece is fixed and the height is adjusted, the laser cutting head 3 can be started to perform the cutting operation. The movable support frame 2 and the movable laser cutting head 3 on the support frame 2 cooperate to flexibly adjust the position of the laser cutting head 3 above the processing plate 1 and cut the workpiece according to the preset trajectory. During the cutting process, the smoke filter component at one end of the laser cutting head 3 works synchronously to deal with the smoke generated by cutting in a timely manner and reduce the impact on the environment and equipment.

[0027] Please see Figures 1-5 As one embodiment of the smoke filtering assembly: the smoke filtering assembly includes a filter tube 15, an exhaust fan 16, and a filter cotton 17. The filter tube 15 is located on one side of the laser cutting head 3, the exhaust fan 16 is located at the upper end of the filter tube 15, the filter cotton 17 passes through the filter tube 15, and a horn-shaped air intake 21 is provided at the lower end of the filter tube 15. The air intake 21 faces the cutting area of ​​the laser cutting head 3.

[0028] Specifically, the exhaust fan 16 generates suction at the upper end of the filter tube 15. Under the action of suction, the smoke generated in the cutting area is drawn in through the funnel-shaped air intake 21 at the lower end of the filter tube 15. The air intake 21 faces the cutting area and is funnel-shaped, which can capture smoke more efficiently. After the smoke enters the filter tube 15, it first passes through the filter cotton 17 that runs through the tube. Harmful substances and particulate matter are intercepted and purified by the filter cotton 17. The purified air is discharged through the exhaust fan 16, thereby reducing the impact of smoke on the environment, operators and equipment.

[0029] Please see Figures 1-5 As one embodiment of the support feet 20: support feet 20 are provided at the four corners of the bottom wall of the base plate 10.

[0030] Specifically, the support feet 20 at the four corners of the bottom wall of the base plate 10 are placed stably on the ground. The contact between the support feet 20 and the ground provides a stable support foundation for the entire laser cutting machine, avoiding direct contact between the equipment and the ground.

[0031] Please see Figures 1-5 As one embodiment of the anti-slip mat: the bottom wall of the pressing plate 9 is provided with an anti-slip mat, which is made of high temperature resistant silicone material and has anti-slip texture on its surface.

[0032] Specifically, the high-temperature resistant silicone anti-slip pad can adapt to the high-temperature environment generated by laser cutting, avoiding deformation or damage due to high temperature. The anti-slip texture on its surface can increase the friction with the workpiece surface, preventing the workpiece from sliding and shifting when pressed and clamped.

[0033] In summary, when using the overall equipment: The operator places the workpiece to be cut on the processing plate 1, and after the workpiece is roughly in the center of the processing plate 1, the first motor 6 is started. The first motor 6 drives the bidirectional threaded rod 4 to rotate. Since the threads on both sides of the bidirectional threaded rod 4 are opposite, the two symmetrical clamping blocks 5 connected to the screw 12 will slide towards each other along the groove in the center of the processing plate 1, gradually approaching the left and right sides of the workpiece, completing the initial horizontal fixation of the workpiece. After the horizontal clamping is stable, the electric push rod 8 on the upper end connecting frame 7 of the clamping block 5 is started. The piston rod of the push rod extends downward, driving the lower end pressing plate 9 to descend vertically until the anti-slip pad on the bottom wall of the pressing plate 9 is tightly attached to the upper surface of the workpiece. The anti-slip pad made of high-temperature resistant silicone material can adapt to the high temperature environment during cutting. The anti-slip texture on the surface can increase the friction with the workpiece, thereby fixing the workpiece in the vertical direction for the second time and avoiding the workpiece from sliding or warping during subsequent cutting.

[0034] The height of the processing plate 1 is adjusted by the height adjustment component to suit the required height. The second motor 14 on the bottom wall of the base plate 10 is started. The output end of the motor drives the screw 12 that passes through the fixed rod 11 to rotate. The adjusting rod 13, which is threaded to the screw 12, rises and falls smoothly in the vertical direction under the guidance and constraint of the fixed rod 11, thereby pushing the processing plate 1 connected to the adjusting rod 13 to rise and fall synchronously. During this process, the limiting components on both sides of the upper side wall of the base plate 10 play an auxiliary stabilizing role. The lifting rod 19 slides along the inner wall of the sliding rod 18 to limit the lifting trajectory of the processing plate 1, preventing the processing plate 1 from tilting due to uneven force on one side, and ensuring that the processing plate 1 always remains horizontal. When the processing plate 1 is adjusted to the appropriate height, the second motor 14 is turned off, and the processing plate 1 is stably maintained at that height. At the same time, the support feet 20 at the four corners of the bottom wall of the base plate 10 are tightly attached to the ground, providing stable support for the entire device and preventing the equipment from shifting during subsequent operations.

[0035] After the processing preparation is completed, the cutting operation stage begins. The laser cutting head 3 is started, and the movable support frame 2 and the laser cutting head 3 are controlled using known technology, so that the cutting head moves above the workpiece along a preset trajectory to complete the cutting operation. During the cutting process, the smoke filter assembly on one side of the laser cutting head 3 is started simultaneously. The exhaust fan 16 generates suction at the upper end of the filter tube 15. The smoke generated in the cutting area is quickly sucked in through the funnel-shaped air intake 21 at the lower end of the filter tube 15 towards the cutting area under the suction. After the smoke enters the filter tube 15, it passes through the filter cotton 17 that runs through the tube. The harmful particles and impurities in the filter cotton 17 are intercepted by the filter cotton 17. The purified air is discharged through the exhaust fan 16, reducing the impact of smoke on the environment and equipment.

For all the fixed connections mentioned above, welding is preferred.

The scope of this utility model is defined by the appended claims and their equivalents. In all the solutions mentioned above, the operation of electrical components is controlled by a controller.
