Description

Technical Field

[0001] The invention relates to the technical field of laser cutting, and in particular to an operating table for a laser cutting machine. Background Art

[0002] A high-power density laser beam is used to irradiate the material to be cut, so that the material is quickly heated to the vaporization temperature and evaporates to form holes. As the beam moves across the material, the holes continuously form very narrow slits to complete the cutting of the material. Laser cutting uses a focused high-power density laser beam to irradiate the workpiece, so that the irradiated material quickly melts, vaporizes, ablates or reaches the ignition point, and at the same time uses a high-speed airflow coaxial with the beam to blow away the molten material, thereby achieving the cutting of the workpiece. Laser cutting is one of the thermal cutting methods.

[0003] Due to the small laser spot, high energy density and fast cutting speed, laser cutting can achieve better cutting quality. A 1200W laser is required to cut a 2mm thick low-carbon steel plate. Thicker plates require higher-power lasers. General laser cutting machines use a serrated operating table to place the plates during cutting. When cutting thicker metal plates, the higher laser rated power and more concentrated pressure will cause local deformation of the operating table, making subsequent cutting inaccurate and unable to meet actual needs. Summary of the invention

[0004] The invention discloses an operating table for a laser cutting machine, aiming to solve the technical problem that a general operating table for a laser cutting machine uses a serrated operating table to place a plate during cutting, and when cutting a thick metal plate, a higher laser rated power and a more concentrated pressure may cause local deformation of the operating table, resulting in inaccurate cutting of subsequent mechanisms.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions: An operating table for a laser cutting machine comprises a platform, a mounting frame is fixedly connected to one side of the platform, sealing plates are fixedly connected to both ends of the platform, an exhaust pipe is plugged into one side of the sealing plate, a plurality of screening rectangular holes are provided on the bottom surface of the platform, a mounting gap is provided at a position near one side of the bottom of the platform, a connecting gap is provided at a position near the mounting gap of the bottom of the platform, and a plurality of ventilation gaps are provided on an inner wall of one side of the platform; A transmission mechanism is installed on one side of the platform, and the transmission mechanism is used to provide power to the equipment; The platform is provided with a laser cutting head capable of moving along the X-axis and the Y-axis; A residue collection mechanism is provided at the bottom of the platform, and the residue collection mechanism is used to collect the residue generated by laser welding; A scrap material collecting mechanism is installed at the bottom of the platform, and the scrap material collecting mechanism is used to collect large pieces of scrap materials; A positioning mechanism is installed on the other side of the platform, and the positioning mechanism is used to stabilize the position of the mechanism; A ventilation mechanism is installed on one side of the platform, and the ventilation mechanism is used to collect smoke generated by laser welding.

[0006] By designing screening rectangular holes, according to the thickness and shape of the plate to be cut, thin and light plates can be laser cut on the platform according to the width of the plate. After multiple cuttings, the metal waste generated by cutting and impurities generated by heating will fall to the bottom of the platform. Through the screening rectangular holes at the bottom of the platform, the metal waste will remain on the bottom surface of the platform, and the small particles of impurities generated by heating will fall to the bottom of the platform, which has the effect of separating metal waste and impurities.

[0007] In a preferred solution, the transmission mechanism includes a motor fixedly connected to the top of the mounting frame, one end of the motor output shaft is fixedly connected to a driving shaft, a plurality of driving bevel gears are fixedly connected to the driving shaft, a plurality of connecting rods are rotatably connected to one side of the platform, and one end of the connecting rod is fixedly connected to a driven bevel gear; A sliding connection mechanism is installed at one end of the connecting rod, and the sliding connection mechanism is used for connection. The sliding connection mechanism includes a rotating cylinder fixedly connected to one end of the connecting rod, one end of the rotating cylinder is slidably connected to a mounting shaft, one end of the mounting shaft is fixedly connected to a rotating slider, and one end of the rotating cylinder is provided with a sliding groove; A rotation support mechanism is installed on the installation shaft, and the rotation support mechanism is used to support the steel plate that needs to be cut.

[0008] By designing a slide groove and a rotating slider, the installation shaft and the rotating slider slide inward, and the rotating slider is inserted into the slide groove. Due to the special shapes of the slide groove and the rotating slider, the rotating slider can rotate with the rotating cylinder. At this time, the motor is started to drive multiple active bevel gears and active shafts to rotate, so that multiple rotating sliders and the installation shafts connected to the rotating cylinder rotate, which has the effect of selectively rotating part of the installation shaft.

[0009] In a preferred embodiment, the residue collection mechanism includes a collection vehicle arranged at the bottom of the platform, the bottom of the collection vehicle is rotatably connected to a plurality of rotating rods, both ends of the rotating rods are respectively fixedly connected to wheels, one end of the collection vehicle is fixedly connected to a handle, and the scrap collection mechanism includes a first slide rail fixedly connected to the inner walls on both sides of the platform, the first slide rail is internally slidably connected to a first slider, one side of the first slider is fixedly connected to a scraper, and the bottom of one end of the scraper is fixedly connected to a fixed rod.

[0010] After a certain amount of metal waste is collected, the handle is pulled manually to pull out the collection vehicle, driving the first slider, the fixing rod and the scraper to move outward together. Since the gap between the scraper and the bottom upper surface of the platform is very small, the scraper slides outward to continuously push the metal waste scattered on the bottom surface of the platform outward, thereby facilitating the collection of metal waste.

[0011] In a preferred embodiment, the rotating support mechanism includes a plurality of square rods arranged on a mounting shaft, both ends of the square rods are respectively provided with threads, a positioning plate is threadedly connected to the threads, a first clamp is arranged at one end of the square rod, a pressure-bearing plate is fixedly connected to the upper surface of the first clamp, a plurality of heat dissipation holes are arranged on one side of the pressure-bearing plate, a second clamp is rotatably connected to one side of the first clamp, a pressure-bearing rod is slidably connected to the bottom of the second clamp, a buffer spring is sleeved on one end of the pressure-bearing rod, and a fixing bolt is threadedly connected to one end of the first clamp.

[0012] By designing a pressure rod and a pressure plate, all the pressure rods and pressure plates on the rotating installation shaft are rotated 180 degrees, and the pressure rods and pressure plates are turned upside down so that the pressure rod faces upward. Due to the rod-shaped design of the pressure rod, when the pressure rod is subjected to pressure, the buffer spring will be compressed to form a buffer, so that it can withstand greater pressure. Due to the small top area of ​​the pressure rod and the disc-shaped design, it will not be deformed when irradiated by the laser beam, thereby ensuring the smoothness of the plate surface and preventing the plate from being scratched.

[0013] Furthermore, after long-term use, the pressure rod or the pressure plate needs to be replaced. By turning the fixing bolt, the first clamp and the second clamp can be rotated relative to each other, and the first clamp and the second clamp are removed and replaced with new ones, which makes replacement convenient. The function of the positioning plate is to limit the position of the first clamp and the second clamp to prevent them from sliding left and right on the square rod.

[0014] In a preferred embodiment, the positioning mechanism includes a positioning cylinder fixedly connected to one end of the mounting shaft, the upper surface and the lower surface of the positioning cylinder are respectively fixedly connected with positioning blocks, the surface of the positioning block is provided with a groove, a plurality of mounting cylinders are respectively fixedly connected to the lower surface of the top of one side of the platform, a mounting cavity is provided inside the mounting cylinder, an insertion rod is slidably connected inside the mounting cavity, one end of the insertion rod is sleeved with a positioning spring, one end of the insertion rod is fixedly connected with a clamping block, one end of the positioning cylinder is fixedly connected with a push rod, one end of the positioning cylinder is fixedly connected with a linkage rod, and one end of the square rod is sleeved with a stop ring.

[0015] By designing a clamping block and a positioning block, when the mounting shaft rotates, the clamping block is separated from the groove on the positioning block, the insertion rod squeezes the positioning spring, and the bottom positioning block of the positioning cylinder contacts the clamping block again, so that the position of the positioning cylinder and the mounting shaft is fixed again to prevent them from rotating, thereby stabilizing the plate.

[0016] In a preferred solution, the ventilation mechanism includes a plurality of second slide rails fixedly connected to one side of the platform, a second slider is slidably connected inside the second slide rail, a sliding plate is fixedly connected to one side of the second slider, and a linkage plate is rotatably connected to the other side of the second slider, one end of the fixing rod passes through a connecting gap and is fixed to one side of the collection vehicle, the fixing bolt is threadedly connected to one end of the second clamp, the stop ring can prevent the first clamp and the second clamp from sliding, the clamping block is stuck in a groove on the positioning block, and one end of the linkage rod is rotatably connected to the linkage plate.

[0017] By manually pushing inward, the two sliding plates are pushed outward respectively, and the ventilation slits at the corresponding positions blocked by the sliding plates are exposed, so that the ventilation slits at this position are connected with the cavity on one side of the platform. When laser cutting is performed, the smoke and exhaust gas generated are sucked in through the corresponding ventilation slits and discharged through the exhaust pipe, so that the ventilation slits at the corresponding positions where metal cutting occurs can be connected with the exhaust pipe, so that the smoke and exhaust gas can be cleaned in time, preventing the smoke from polluting the indoor air, and achieving the effect of flexible exhaust.

[0018] As can be seen from the above, the operating table for a laser cutting machine provided by the present invention has the following technical effects.

[0019] First: By designing a pressure-bearing rod and a pressure-bearing plate, the pressure-bearing rod faces upward. Due to the rod-shaped design of the pressure-bearing rod, when the pressure-bearing rod is subjected to pressure, the buffer spring will be compressed to form a buffer, so that it can withstand greater pressure. Due to the small top area of ​​the pressure-bearing rod and the disc-shaped design, it will not deform when irradiated by the laser beam, thereby ensuring the smoothness of the plate surface and preventing scratches on the plate.

[0020] Secondly: by exposing the ventilation slits blocked by the sliding plate at the corresponding position, the ventilation slits at that position are connected with the cavity on one side of the platform, and the generated smoke and exhaust gas are sucked in through the corresponding ventilation slits, so that the ventilation slits at the corresponding position where metal cutting occurs can be connected with the exhaust pipe, so that the smoke and exhaust gas can be cleaned in time, preventing smoke from polluting the indoor air, and achieving the effect of flexible exhaust.

[0021] Thirdly, by designing a slide groove and a rotating slider, the installation shaft and the rotating slider slide inward, and the rotating slider is inserted into the slide groove. Due to the special shapes of the slide groove and the rotating slider, the rotating slider can rotate with the rotating cylinder. At this time, the motor is started to drive multiple active bevel gears and active shafts to rotate, so that multiple rotating sliders and the installation shaft connected to the rotating cylinder rotate, which has the effect of selectively rotating part of the installation shaft.

DETAILED DESCRIPTION

Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0032] The operating table for a laser cutting machine disclosed in the present invention is mainly used in general laser cutting machine operating tables. When cutting, a serrated operating table is used to place a plate. When cutting a thick metal plate, a higher laser rated power and more concentrated pressure may cause local deformation of the operating table, resulting in inaccurate cutting by subsequent mechanisms.

[0034] In this embodiment, a supporting mechanism is used to prop up the bottom of the platform 1 on the ground of the site, and the top of the platform 1 is leveled so that the top plane of the platform 1 is horizontal. A laser cutting head is installed on the top of the platform 1, and a ventilation device is connected to one end of the exhaust pipe 9. According to the thickness and shape of the plate to be cut, the thickness is small and thin, and according to the width of the plate, after multiple cuttings, the metal waste generated by cutting and the impurities generated by heating will fall to the bottom of the platform 1. Through the screening rectangular holes at the bottom of the platform 1, the metal waste will remain on the bottom surface of the platform 1, and the small granular impurities generated by heating will fall to the bottom of the platform 1, thereby separating the metal waste and impurities.

[0035] Reference Figure 1 , Figure 2 , Figure 4 , Figure 5 and Figure 6 In a preferred embodiment, the transmission mechanism includes a motor 12 fixedly connected to the top of the mounting frame 2, one end of the output shaft of the motor 12 is fixedly connected to a driving shaft 15, and the driving shaft 15 is fixedly connected to a plurality of driving bevel gears 16, and one side of the platform 1 is rotatably connected to a plurality of connecting rods 14, and one end of the connecting rod 14 is fixedly connected to a driven bevel gear 13; A sliding connection mechanism is installed at one end of the connecting rod 14, and the sliding connection mechanism is used for connection. The sliding connection mechanism includes a rotating cylinder 24 fixedly connected to one end of the connecting rod 14, one end of the rotating cylinder 24 is slidably connected to the installation shaft 4, one end of the installation shaft 4 is fixedly connected to the rotating slider 25, and one end of the rotating cylinder 24 is provided with a sliding groove 26; A rotation support mechanism is installed on the installation shaft 4, and the rotation support mechanism is used to support the steel plate to be cut.

[0036] In this embodiment, when it is necessary to cut a plate with a larger thickness, the laser cutting power also needs to be increased accordingly due to the larger mass and more concentrated pressure. Therefore, the larger pressure and high-power laser beam may damage the surface of the equipment, causing the mounting shaft 4 and the rotating slider 25 to slide inward, and the rotating slider 25 to be inserted into the slide groove 26. Due to the special shapes of the slide groove 26 and the rotating slider 25, the rotating slider 25 can rotate with the rotating cylinder 24. At this time, the motor 12 is started to drive the multiple active bevel gears 16 and the active shaft 15 to rotate, so that the multiple rotating sliders 25 connected to the rotating cylinder 24 and the mounting shaft 4 rotate, thereby achieving the effect of selectively rotating part of the mounting shaft 4.

[0037] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 In a preferred embodiment, the residue collection mechanism includes a collection vehicle 7 arranged at the bottom of the platform 1, and the bottom of the collection vehicle 7 is rotatably connected to a plurality of rotating rods 8, and wheels 18 are fixedly connected at both ends of the rotating rods 8. A handle 6 is fixedly connected to one end of the collection vehicle 7, and the scrap material collection mechanism includes a first slide rail 21 fixedly connected to the inner walls on both sides of the platform 1, and a first slider 20 is slidably connected inside the first slide rail 21, and a scraper 19 is fixedly connected to one side of the first slider 20, and a fixed rod 22 is fixedly connected to the bottom of one end of the scraper 19.

[0038] In this embodiment, after a certain amount of material is collected, the handle 6 is pulled by manpower to pull out the collection vehicle 7. The wheels 18 at the bottom of the collection vehicle 7 can reduce friction, making it easier to pull the collection vehicle 7. The collection vehicle 7 slides outward, driving the first slider 20, the fixing rod 22 and the scraper 19 to move outward together. Since the gap between the scraper 19 and the bottom upper surface of the platform 1 is extremely small, the scraper 19 slides outward to continuously push the metal waste scattered on the bottom surface of the platform 1 outward, thereby facilitating the collection of metal waste.

[0039] Reference Figure 1 , Figure 2 , Figure 3 and Figure 8 In a preferred embodiment, the rotation support mechanism includes a plurality of square rods 43 arranged on the mounting shaft 4, threads are respectively provided at both ends of the square rods 43, a positioning plate 38 is threadedly connected to the threads, a first clamping jaw 39 is provided at one end of the square rod 43, a pressure-bearing plate 45 is fixedly connected to the upper surface of the first clamping jaw 39, a plurality of heat dissipation holes 46 are provided on one side of the pressure-bearing plate 45, a second clamping jaw 40 is rotatably connected to one side of the first clamping jaw 39, a pressure-bearing rod 41 is slidably connected to the bottom of the second clamping jaw 40, a buffer spring 42 is sleeved on one end of the pressure-bearing rod 41, and a fixing bolt 44 is threadedly connected to one end of the first clamping jaw 39.

[0040] In this embodiment, all the pressure rods 41 and pressure plates 45 on the rotating installation shaft 4 are rotated 180 degrees, and the pressure rods 41 and pressure plates 45 are turned upside down so that the pressure rods 41 face upward. Due to the rod-shaped design of the pressure rods 41, when the pressure rods 41 are subjected to pressure, the buffer springs 42 will be compressed to form a buffer, so that it can withstand greater pressure. Due to the small top end area and disc-shaped design of the pressure rods 41, no deformation will occur when irradiated by the laser beam, thereby ensuring the smoothness of the plate surface and preventing scratches on the plate.

[0041] Furthermore, after long-term use, the pressure rod 41 or the pressure plate 45 needs to be replaced. By rotating the fixing bolt 44, the first clamp 39 and the second clamp 40 can rotate relative to each other, and the first clamp 39 and the second clamp 40 are removed and replaced with new ones, which makes replacement convenient. The function of the positioning plate 38 is to limit the position of the first clamp 39 and the second clamp 40 to prevent them from sliding left and right on the square rod 43.

[0042] Reference Figure 1 , Figure 2 , Figure 3 and Figure 7In a preferred embodiment, the positioning mechanism includes a positioning cylinder 29 fixedly connected to one end of the mounting shaft 4, and the upper and lower surfaces of the positioning cylinder 29 are respectively fixedly connected with positioning blocks 30, and the surface of the positioning block 30 is provided with a groove, and a plurality of mounting cylinders 10 are respectively fixedly connected to the lower surface of the top of one side of the platform 1, and a mounting cavity 31 is provided inside the mounting cylinder 10, and an insertion rod 33 is slidably connected inside the mounting cavity 31, and a positioning spring 32 is sleeved on one end of the insertion rod 33, and a clamping block 34 is fixedly connected to one end of the positioning cylinder 29, and a push rod 36 is fixedly connected to one end of the positioning cylinder 29, and a linkage rod 35 is fixedly connected to one end of the square rod 43, and a stop ring is sleeved on one end.

[0043] In this embodiment, when the mounting shaft 4 rotates, the block 34 is separated from the groove on the positioning block 30, the insertion rod 33 squeezes the positioning spring 32, and the bottom positioning block 30 of the positioning cylinder 29 contacts the block 34 again, so that the position of the positioning cylinder 29 and the mounting shaft 4 is fixed again to prevent them from rotating, thereby stabilizing the plate.

[0044] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 In a preferred embodiment, the ventilation mechanism includes a plurality of second slide rails 27 fixedly connected to one side of the platform 1, a second slider 28 is slidably connected inside the second slide rail 27, a sliding plate 23 is fixedly connected to one side of the second slider 28, and a linkage plate 37 is rotatably connected to the other side of the second slider 28. One end of the fixing rod 22 passes through the connecting gap 17 and is fixed to one side of the collection vehicle 7. The fixing bolt 44 is threadedly connected to one end of the second clamping jaw 40. The stop ring can prevent the first clamping jaw 39 and the second clamping jaw 40 from sliding. The block 34 is stuck in the groove on the positioning block 30, and one end of the linkage rod 35 is rotatably connected to the linkage plate 37.

[0045] In this embodiment, manual pushing inward drives the linkage rod 35 to slide inward, pushing the two linkage plates 37 to rotate, so that the two second sliders 28 slide outward respectively, and the two sliding plates 23 are pushed outward respectively, exposing the ventilation slits 5 blocked by the sliding plates 23 at the corresponding positions, so that the ventilation slits 5 at this position are connected with the cavity on one side of the platform 1. When laser cutting is performed, the generated smoke and exhaust gas are sucked in through the corresponding ventilation slits 5 and discharged through the exhaust pipe 9, so that the ventilation slits 5 at the corresponding positions where metal cutting occurs can be connected with the exhaust pipe 9, so that the smoke and exhaust gas can be cleaned in time, preventing the smoke from polluting the indoor air, and achieving the effect of flexible exhaust.

[0046] Working principle: When in use, the bottom of the platform 1 is propped up on the ground of the site with a supporting mechanism, and the top of the platform 1 is leveled to make the top plane of the platform 1 horizontal. The laser cutting equipment is installed on the top of the platform 1, and the ventilation equipment is connected to one end of the exhaust pipe 9. According to the thickness and shape of the plate to be cut, the pressure plate 45 is used as a support for the thin and light plate. According to the width of the plate, on one side of the platform 1, several push rods 36 at the position where the plate is placed are manually pushed inward, driving the linkage rod 35 to slide inward, pushing the two linkage plates 37 to rotate, so that the two second sliders 28 slide outward respectively, and the two sliding plates 23 are pushed outward respectively, so that the ventilation gap 5 blocked by the sliding plate 23 at the corresponding position is exposed, so that the position The ventilation slits 5 are connected with the cavity on one side of the platform 1, and the plate is placed on multiple pressure-bearing plates 45 for laser cutting. When laser cutting is performed, the smoke and exhaust gas generated are sucked in through the corresponding ventilation slits 5 and discharged through the exhaust pipe 9, so that the ventilation slits 5 at the corresponding positions where metal cutting occurs can be connected with the exhaust pipe 9, so that the smoke and exhaust gas can be cleaned in time to prevent smoke from polluting the indoor air, and the effect of flexible exhaust is achieved. After multiple cuttings, the metal waste generated by cutting and the impurities generated by heating will fall to the bottom of the platform 1, and the metal waste will remain on the bottom surface of the platform 1 through the screening rectangular holes at the bottom of the platform 1, and the small particles of impurities generated by heating will fall into the collection vehicle 7 at the bottom of the platform 1, which has the effect of separating the metal waste and impurities, and collecting to a certain extent. After the amount is measured, the handle 6 is pulled by manpower to pull out the collection vehicle 7. The wheels 18 at the bottom of the collection vehicle 7 can reduce friction, making it easier to pull the collection vehicle 7. The collection vehicle 7 slides outward, driving the first slider 20, the fixing rod 22 and the scraper 19 to move outward together. Since the gap between the scraper 19 fixedly connected and the bottom upper surface of the platform 1 is extremely small, the scraper 19 slides outward to continuously push the metal waste scattered on the bottom surface of the platform 1 outward, thereby facilitating the collection of metal waste. When it is necessary to cut a thicker plate, the laser cutting power also needs to be increased accordingly due to the greater mass and more concentrated pressure. Therefore, the greater pressure and high-power laser beam may damage the surface of the pressure-bearing sheet 45, causing scratches on the surface of the plate that subsequently contacts the pressure-bearing sheet 45. The plurality of push rods 36 in the area where the thick plate is placed are pushed inward, so that the installation shaft 4 and the rotating slider 25 slide inward, and the rotating slider 25 is inserted into the slide groove 26. Due to the special shapes of the slide groove 26 and the rotating slider 25, the rotating slider 25 can rotate with the rotating cylinder 24. At this time, the motor 12 is started to drive the plurality of active bevel gears 16 and the active shaft 15 to rotate, so that the plurality of rotating sliders 25 and the installation shaft 4 connected with the rotating cylinder 24 rotate, so that all the pressure-bearing rods 41 and the pressure-bearing plates 45 on the rotating installation shaft 4 rotate 180 degrees, and the pressure-bearing rod 41 and the pressure-bearing plates 45 are turned upside down, so that the pressure-bearing rod 41 faces upward. Due to the rod-shaped design of the pressure-bearing rod 41, when the pressure-bearing rod 41 is subjected to pressure, the buffer spring 42 will be compressed to form a buffer.It can withstand greater pressure. Due to the small top area and disc-shaped design of the pressure rod 41, it will not deform when irradiated by the laser beam, ensuring the smoothness of the plate surface and preventing scratches on the plate. When the installation shaft 4 rotates, the block 34 separates from the groove on the positioning block 30, and the insertion rod 33 squeezes the positioning spring 32. The bottom positioning block 30 of the positioning cylinder 29 re-contacts the block 34, so that the position of the positioning cylinder 29 and the installation shaft 4 is fixed again to prevent them from rotating, which plays a role in stabilizing the plate. After long-term use, the pressure rod 41 or the pressure plate 45 needs to be replaced. By rotating the fixing bolt 44, the first clamping jaw 39 and the second clamping jaw 40 can rotate relative to each other. The first clamping jaw 39 and the second clamping jaw 40 are removed and replaced with new ones. The role of the positioning plate 38 is to limit the position of the first clamping jaw 39 and the second clamping jaw 40 to prevent them from sliding left and right on the square rod 43.

Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
