Description

Technical Field

[0001] The present invention relates to the technical field of laser cutting devices, and in particular to a large-scale transversely enclosed laser cutting machine. Background Art

[0002] A laser cutting machine is a machine that uses a high-energy-density laser beam to cut and process materials. Laser cutting technology has the following advantages: It uses a high-energy laser beam for cutting, resulting in extremely high cutting accuracy. It can precisely cut within a millimeter or even smaller size range, ensuring the dimensional accuracy and geometric consistency of the workpiece. Laser cutting is a non-contact cutting technology; the laser beam does not directly contact the material being processed, so it does not exert physical force or thermal stress on the material, reducing the risk of damage to the workpiece and avoiding quality degradation due to tool wear. Laser cutting machines use a high-energy laser beam for cutting, resulting in a smaller heat-affected area. Due to the high energy density of the laser beam, the material can be locally heated to its melting point and cut in a short period of time, thereby reducing the thermal impact and deformation of the surrounding area. Common laser cutting machines include metal laser cutting machines, non-metal laser cutting machines, and fully automatic laser cutting machines. Laser cutting machines are widely used in the automotive, electronics, machinery manufacturing, aerospace, and electric power industries, and are increasingly being used in intelligent manufacturing.

[0003] However, the existing laser cutting device has some shortcomings during use and still needs to be improved. For example, patent number CN202021240350.2 is a laser cutting machine with an exchange workbench, which includes a laser cutting machine upper seat, a laser cutting machine lower seat and a laser cutting head seat; one side of the laser cutting machine upper seat is connected to a first gear bar, and the lower seat of the laser cutting machine is connected to a second gear bar; the bottom of the laser cutting head seat is connected to a laser nozzle and an exhaust gas absorption box, and the exhaust gas absorption box is located on both sides of the laser nozzle.

DETAILED DESCRIPTION

[0032] The preferred embodiments of the present invention are described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0033] Example 1: Reference Figure 1 and Figure 5A horizontal large-surround laser cutting machine includes: an exchange table 1, a motor is provided inside the exchange table 1, the output end of the motor is connected to the transmission mechanism 4, the transmission mechanism 4 is connected to the upper cutting table 2 and the lower cutting table 3, the upper cutting table 2 and the lower cutting table 3 slide parallel to each other in the exchange table 1, a Y-direction moving mechanism 6 is provided on the exchange table 1, an X-direction moving mechanism 5 is provided on the Y-direction moving mechanism 6, a lifting mechanism is provided on the X-direction moving mechanism 5, a laser and a cleaning mechanism 7 are provided on the lifting mechanism, and the laser is located inside the cleaning mechanism 7.

[0034] The working principle and beneficial effects of the above technical solution are:

[0035] After the cutting machine completes cutting the parts on the lower cutting table 3, the output end of the motor drives the transmission mechanism 4 to move. The movement of the transmission mechanism 4 drives the lower cutting table 3 and the upper cutting table 2 to move parallel to each other in the exchange table 1. After the lower cutting table 3 is moved to the discharge end and the parts on the upper cutting table 2 are moved to the processing position, the movement of the Y-direction moving mechanism 6 drives the X-direction moving mechanism 5 to move, and the X-direction moving mechanism 5 drives the lifting mechanism to move. The lifting mechanism is specifically a structure in which the lifting motor drives the lead screw to drive the screw block. The screw block is connected to one side wall of the mounting plate, and the other side wall of the mounting plate is connected to the laser and the cleaning mechanism. 7 is connected, the laser is located on the inner side of the cleaning mechanism 7, the lifting motor rotates to drive the rotation of the lead screw, the rotation of the lead screw drives the movement of the screw block, the movement of the screw block drives the movement of the mounting plate, the mounting plate adjusts the position of the laser to process the parts, and during the laser processing of the parts, the cleaning mechanism 7 cleans and cools the laser; by lengthening the stroke of the X-axis moving mechanism and shortening the stroke of the Y-axis moving mechanism, the time for part exchange is shortened, thereby improving the exchange efficiency of the exchange table; a large surrounding protective shell is installed on the side wall of the exchange table 1 to prevent the laser from hurting people's eyes during the cutting process.

[0036] Example 2: Reference Figure 2 The Y-direction moving mechanism 6 includes: a mounting plate 8, a mounting plate 8 is respectively installed on the top of the two side walls of the exchange table 1, a Y-bevel rack 9 and a Y slide rail are arranged in parallel on the mounting plate 8, a Y slider 10 is slidably connected to the Y slide rail, and a Y motor is provided on the Y slider 10. The output end of the Y motor is connected to the Y-bevel rack 9 through a first bevel gear, and the top surface of the Y slider 10 is connected to the X-direction moving mechanism 5.

[0037] The working principle and beneficial effects of the above technical solution are:

[0038] The Y slider 10 is slidably connected to the Y slide rail. The X motor output shaft on the Y slider 10 rotates to drive the first bevel gear to rotate. When the first bevel gear is engaged with the Y bevel rack for transmission, it provides power for the movement of the Y slider 10 on the Y slide rail. The movement of the Y slider 10 drives the X-direction moving mechanism 5 on the Y slider 10 to move. Through the meshing transmission between the first bevel gear and the Y bevel rack, the accuracy of the movement of the Y-direction moving mechanism 6 is improved, the accuracy of the cutting of the part in the Y-axis direction is improved, the noise generated during the movement of the mechanism is reduced, and the carrying capacity of the mechanism is improved.

[0039] Example 3: Reference Figure 3 The X-direction moving mechanism 5 includes: a crossbeam 11, the top surfaces of the two Y sliders 10 are respectively connected to one end of the crossbeam 11, an X-bevel rack 12 and an X-slide rail are provided parallel to the upper end surface of the crossbeam 11, an X-slide block 13 is slidably connected to the X-slide rail, an X-motor is installed on the X-slide block 13, the output end of the X-motor is connected to the X-bevel rack 12 through a second bevel gear, and the side wall of the X-slide block 13 is connected to the lifting mechanism.

[0040] The working principle and beneficial effects of the above technical solution are:

[0041] The top surfaces of the two Y sliders 10 are respectively fixedly connected to the bottom walls at both ends of the beam 11. The upper end surface of the beam 11 is parallel to an X-bevel rack 12 and an X-slide rail. The X slider 13 is slidably connected to the X-slide rail. The rotation of the output end of the X motor on the X slider 13 drives the second bevel gear to rotate. When the second bevel gear is engaged with the X-bevel rack 12 for transmission, it provides power for the sliding of the X slider 13 on the X-slide rail. The X slider 13 moves linearly along the X-bevel rack 12. The X slider 13 drives the lifting mechanism, the cleaning mechanism 7 and the laser to move to the cutting position. Through the meshing transmission between the second bevel gear and the X-bevel rack 12, the accuracy of the movement of the X-axis moving mechanism is improved, the accuracy of the cutting of the part in the X-axis direction is improved, the noise generated during the movement of the mechanism is reduced, and the carrying capacity of the mechanism is improved.

[0042] Example 4: Reference Figure 8 One end of the upper cutting table 2 and the lower cutting table 3 are both provided with a plurality of silicone columns 14, and the ends of the silicone columns 14 cooperate with the inner end wall of the exchange table 1 to buffer the upper cutting table 2 and the lower cutting table 3.

[0043] The working principle and beneficial effects of the above technical solution are:

[0044] The forward rotation of the motor drives the transmission mechanism 4 to rotate, and the rotation of the transmission mechanism 4 drives the upper cutting table 2 and the lower cutting table 3 to move towards each other. The lower cutting table 3 moves away from the inner end wall of the exchange table 1, and the ends of the multiple silicone columns 14 at one end of the lower cutting table 3 are out of contact with the inner end wall of the exchange table 1. The upper cutting table 2 approaches the inner end wall of the exchange table 1. When the upper cutting table 2 reaches the processing position, the ends of the multiple silicone columns 14 at one end of the upper cutting table 2 are in contact with the inner end wall of the exchange table 1 and buffer the upper cutting table 2. By arranging silicone columns 14 on the side walls of the upper cutting table 2 and the lower cutting table 3 for exchange into position buffering and fixing them to the inner end wall of the exchange table 1, it is ensured that the upper cutting table 2 or the lower cutting table 3 exchanged into position is stable, thereby improving the cutting accuracy.

[0045] Example 5: Reference Figure 1 、 Figure 5 、 Figure 8 and Figure 9 The transmission mechanism 4 includes: a transmission shaft 15, one end of the transmission shaft 15 is rotatably mounted on the two inner walls of the exchange table 1, the transmission shaft 15 is connected to the output end of the motor, and two first sprockets 16 are mounted on the transmission shaft 15. A second sprocket 17 is rotatably mounted on the two inner walls of the exchange table 1, and the second sprocket 17 and the first sprocket 16 on the same side are connected by a chain transmission. The upper side of the chain is connected to the upper cutting table 2, and the lower side of the chain is connected to the lower cutting table 3.

[0046] The working principle and beneficial effects of the above technical solution are:

[0047] The motor and the transmission shaft 15 are connected through a bevel gear set. The forward rotation of the motor drives the forward rotation of the transmission shaft 15, and the forward rotation of the transmission shaft 15 drives the forward rotation of the first sprocket 16. The upper and lower sides of the chain move in opposite directions under the rotation of the first sprocket 16 and the auxiliary rotation of the second sprocket 17. The upper side of the chain is connected to the upper cutting table 2, and the upper side of the chain drives the upper cutting table 2 to move toward the inner end wall of the exchange table 1. The lower side of the chain is connected to the lower cutting table 3, and the lower side of the chain drives the lower cutting table 3 to move away from the inner end wall of the exchange table 1. The exchange table 1 adopts a chain coaxial drive method to ensure the synchronous operation of multiple chains, thereby solving the high-speed and stable exchange operation of the upper cutting table 2 and the lower cutting table 3.

[0048] Example 6: Reference Figure 5 and Figure 8 The upper cutting table 2 includes: an upper frame 18 and an upper connecting plate 19. An upper hexagonal guide rail is installed on each inner wall of the exchange table 1. A plurality of first guide wheels are equidistantly rotated on the upper hexagonal guide rail. The first guide wheel is rotatably installed at the bottom end of the upper frame 18. The side wall of the upper frame 18 is equipped with an upper connecting plate 19. The bottom end of the upper connecting plate 19 is connected to the upper side of the chain. A plurality of longitudinal knife strips are installed in parallel in the upper frame 18.

[0049] The working principle and beneficial effects of the above technical solution are:

[0050] The positive rotation of the upper side of the chain drives the upper connecting plate 19 to move toward the inner end wall of the exchange platform 1. The side walls of the multiple first guide wheels symmetrically installed at the bottom end of the upper frame 18 rotate and cooperate with the upper part of the upper hexagonal guide rails installed on the two inner walls of the exchange platform 1. The upper connecting plate 19 drives the upper frame 18 to move along the upper hexagonal guide rails toward the inner end wall of the exchange platform 1, ensuring high-speed and stable operation of the mechanism; multiple longitudinal knife strips are installed in parallel in the upper frame 18, and the multiple longitudinal knife strips are arranged in parallel to facilitate the material to fall into the receiving car below the exchange platform 1 during cutting.

[0051] Example 7: Reference Figure 5 and Figure 9 The lower cutting table 3 includes: a lower frame 20 and a lower connecting plate 21. A lower hexagonal guide rail is installed on each inner wall of the exchange table 1. A plurality of second guide wheels are equidistantly connected to the lower hexagonal guide rail for rotation. The second guide wheels are rotatably installed at the bottom end of the lower frame 20. A lower connecting plate 21 is installed on the side wall of the lower frame 20. The bottom end of the lower connecting plate 21 is connected to the lower side of the chain. A plurality of longitudinal blades are installed in parallel in the lower frame 20.

[0052] The working principle and beneficial effects of the above technical solution are:

[0053] The reverse rotation of the lower side of the chain drives the lower connecting plate 21 to move away from the inner end wall of the exchange platform 1. The side walls of the multiple second guide wheels symmetrically installed at the bottom of the lower frame 20 rotate and cooperate with the upper part of the lower hexagonal guide rails installed on the two inner walls of the exchange platform 1. The lower connecting plate 21 drives the lower frame 20 to move along the lower hexagonal guide rails away from the inner end wall of the exchange platform 1, ensuring the high-speed and stable operation of the mechanism; multiple longitudinal knife strips are installed in parallel in the lower frame 20, and the multiple longitudinal knife strips are arranged in parallel to facilitate the material to fall into the receiving car under the exchange platform 1 during cutting.

[0054] Example 8: Reference Figure 4 、 Figure 6 and Figure 7 The cleaning mechanism 7 includes: a shell 22, a shell 22 is installed on the side wall of the lifting mechanism, and an exhaust fan 23 is installed on each side wall of the shell 22. The bottom end of the shell 22 is connected to an adjustment component 25, and the two ends of the adjustment component 25 are respectively arranged below an air inlet of the exhaust fan 23. The adjustment component 25 is connected to the bottom end of the air intake component 24 through a U-shaped plate 31, and the end of the air intake component 24 that passes through the top surface of the shell 22 is connected to the blower. A laser is installed in the shell 22, and the output end of the air intake component 24 is arranged toward the laser. The output end of the laser passes through the bottom surface of the shell 22, and a plurality of cleaning pipes 26 are connected to the bottom surface of the shell 22. The plurality of cleaning pipes 26 are arranged around the output end of the laser, and a plurality of circular holes opened in a linear array on the side wall of the cleaning pipe 26 are arranged toward the output end of the laser.

[0055] The working principle and beneficial effects of the above technical solution are:

[0056] When the laser is working, the exhaust fan 23 and the blower start working at the same time. The blower supplies air to the top of the air intake component 24. The air intake component 24 guides the airflow input by the blower to the surrounding of the laser in the shell 22 to cool the laser. The cooled airflow passes through the multiple circular holes on the side wall of the cleaning tube 26 at the bottom end of the shell 22 and is discharged from the mechanism. The multiple circular holes are all set toward the output end of the laser. The multiple circular holes blow away the smoke and metal splashes around the output end of the laser, so that a protective area composed of airflow is formed around the output end of the laser to prevent high-temperature gas and high-temperature metal splashes from damaging the output end of the laser, thereby improving the safety of the equipment during operation and extending the service life of the equipment. When the high-temperature smoke and high-temperature metal splashes generated by laser cutting metal continue to increase, the high-temperature smoke and high-temperature metal splashes are sucked away by the exhaust fan 23, and after cooling The smoke and metal splashes are discharged out of the device, avoiding the harm to the human body caused by the smoke and metal splashes, and protecting other mechanisms in the device from the influence of the smoke and metal splashes. In the process of the exhaust fan 23 sucking the high-temperature smoke and metal splashes, the high-temperature smoke and metal splashes first pass through the adjusting component 25 and then enter the air inlet of the exhaust fan 23. The adjusting component 25 is deformed by heat and the height of the adjusting component 25 is lowered. The lowering of the height of the adjusting component 25 drives the air inlet component 24 to move downward, increasing the cooling airflow for the laser in the shell 22. The increased cooling airflow is blown out through the circular hole on the side wall of the cleaning tube 26, increasing the protection range of the cleaning tube 26 for the laser output end, preventing the cleaning tube 26 from failing to blow away the smoke and metal splashes at the laser output end in time after a large amount of smoke is generated due to long-term cutting. At the same time, the increased airflow further increases the heat dissipation effect of the laser that works for a long time.

[0057] Example 9: Reference Figure 7 The adjustment component 25 includes: a heat-sensitive expansion member 27 and a folding piece 28. Both side walls of the shell 22 are provided with through grooves, and a sealing block 32 slides in the through groove. The top and bottom surfaces of the sealing block 32 are respectively connected to the top and bottom walls of the through groove through a folding piece 28. The U-shaped plate 31 is connected to the top of the heat-sensitive expansion member 27 through the sealing block 32. The heat-sensitive expansion member 27 is arranged below the air inlet of the exhaust fan 23, and the bottom end of the heat-sensitive expansion member 27 is connected to the bottom surface of the shell 22.

[0058] The working principle and beneficial effects of the above technical solution are:

[0059] The laser cuts metal materials for a long time and generates a large amount of high-temperature smoke and metal splashes. In the process of the high-temperature smoke and metal splashes passing through the heated expansion member 27 and entering the exhaust fan 23, the high-temperature smoke and metal splashes heat the heated expansion member 27. The heated expansion member 27 can be a bimetallic strip made of two different materials. When the temperature changes, objects have the characteristics of thermal expansion and contraction. When heated and expanded, the bimetallic strips will expand, but the degree of thermal expansion is different. The side with greater expansion will bend toward the side with less expansion. For example, an iron metal strip is used on one side of the heated expansion member 27, and a copper metal strip is used on the other side. When heated, the expansion degree of the iron metal strip is greater than that of the copper metal strip, and the iron metal strip bends toward the side of the copper metal strip, resulting in the overall expansion of the heated expansion member 27. The height becomes lower, and the height of the heat expansion member 27 becomes lower, driving the sealing block 32 to move downward in the through groove. The downward movement of the sealing block 32 drives the bottom end of the air intake assembly 24 to move downward, the air intake volume of the air intake assembly 24 increases, and the cooling effect of the air intake assembly 24 on the laser is increased, thereby improving the automation effect of the mechanism; a folding piece 28 is connected to the upper and lower surfaces of the sealing block 32, and the sealing block 32 divides the through groove into two upper and lower through grooves with variable longitudinal cross-sectional areas. The two folding pieces 28 are respectively placed in the upper and lower through grooves, and the two folding pieces 28 are sealed and fitted with the side walls of the upper and lower through grooves. When the air intake assembly 24 cools the laser, the air flow is prevented from blowing out of the through groove, thereby improving the sealing effect in the shell 22, reducing the protection effect of the cleaning tube 26 on the output end of the laser, and improving the protection effect of the equipment.

[0060] Example 10: Reference Figure 7 The air intake assembly 24 includes: a sleeve 29 and a plug 30. Multiple sleeves 29 are installed on the top of the shell 22. The top of the sleeve 29 is connected to the output end of the blower. The side wall of the sleeve 29 is provided with an inverted U-shaped opening. The plug 30 is slidably connected inside the sleeve 29. The side wall of the plug 30 is provided with a U-shaped opening. The inverted U-shaped opening and the U-shaped opening cooperate to form a ventilation port. The ventilation port is set toward the laser. The bottom end of the plug 30 is connected to the U-shaped plate 31.

[0061] The working principle and beneficial effects of the above technical solution are:

[0062] The cannula 30 is slidably connected in the sleeve 29. The side walls of the sleeve 29 and the cannula 30 are respectively provided with a U-shaped opening. The two U-shaped openings cooperate with each other to form an air guide port. The blower blows the air flow in from the top of the sleeve 29 toward the air guide port of the laser to directly cool the laser. After the laser has been working for a long time, the heat expansion height of the heat expansion member 27 becomes lower, the heat expansion member 27 drives the sealing block 32 to move downward, the heat expansion member 27 drives the U-shaped plate 31 to move downward, and the U-shaped plate 31 drives the cannula 30 to move downward, the air guide port area becomes larger, the air intake volume becomes larger, and the airflow area acting on the laser becomes larger, thereby improving the cooling effect of the mechanism and the degree of automation of the mechanism.

They can be fully applied to various fields suitable for the present invention. For those familiar with the art, additional modifications can be easily implemented.
