DETAILED DESCRIPTION

[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0028] like Figures 1 to 9 As shown, the embodiment of the present invention provides a numerically controlled intelligent gantry-type three-dimensional laser cutting machine, including a base 1, a machine frame 2, a gantry 14 and a machine arm-type cutting end 15. A support component 3 is provided inside the machine frame 2, and a support conical tube 5 is sleeved inside the support component 3. The bottom of the support conical tube 5 is fixedly connected with a distribution component 4, and a negative pressure component 6 is provided at the bottom of the distribution component 4. The negative pressure component 6 sucks the air inside the support conical tube 5 through the distribution component 4. A leveling component 7 is provided above the machine frame 2 of the support component 3, and a leveling block 11 is fixedly connected to one end of the leveling component 7. The negative pressure component 6 sucks the air in the leveling component 7 through the machine frame 2. There are two leveling components 7, which are symmetrically distributed above the support component 3. Pushing mechanisms are provided on both sides of the machine frame 2, and the pushing mechanisms drive the leveling component 7 to move horizontally. The leveling component 7 includes a connecting block 71, a curved rod 72, a sleeve 73, a slider 74, an elastic sealing gasket 75, a spring 76 and a curved hole 77. The connecting block 71 is fixed on the top of the leveling block 11.

[0029] Embodiment 1: When in use, the thin plate to be cut is placed on the top surface of the carrier plate 31 of the support assembly 3 and in contact with the top of the supporting conical tube 5, the vacuum pump 62 in the negative pressure assembly 6 is started, and the reversing valve is activated, and the vacuum pump 62 sucks the air inside the middle frame 61, and sucks the air in the leveling assemblies 7 on both sides through the air pipe 63 and the first hole 8, and sucks the air in the sleeve 73 through the aligned curved holes 77. The air pressure inside the sleeve 73 is reduced, driving the curved rod 72 to move downward, compressing the spring 76, and driving the connecting block The two leveling blocks 71 and the leveling block 11 move downward, so that the two leveling blocks 11 in the middle of the top of the thin plate move downward and contact and press on the top surface of the thin plate, and the pushing mechanism is started, so that the electric push rods 12 on both sides respectively drive the leveling components 7 on both sides to move in the opposite direction through the connecting frame 13, so that the two leveling blocks 11 slide along the center position of the top surface of the thin plate and slide toward both sides, pressing the thin plate downward and leveling it, and when the leveling component 7 moves away from the No. 1 hole 8, it slides along the side of the machine frame 2 through the elastic sealing gasket 75, and the internal pressure of the leveling component 7 is maintained to maintain the compression and leveling. As the leveling is about to be completed, the reversing valve is activated, and the vacuum pump 62 directly sucks the air in the distribution frame 41 in the distribution component 4, thereby sucking the air inside the connected support cone tube 5. When the thin plate is leveled and seals the top of the support cone tube 5, the negative pressure inside the support cone tube 5 makes the flattened thin plate adsorbed and fixed on the top of the support cone tube 5. When the leveling is completed, the thin plate is completely adsorbed and fixed on the top of the support cone tube 5 distributed in the array, and the sealing component 10 is started. The electric push rod 103 drives the sealing plate 101 to move horizontally and cover At the bottom connection of the supporting conical tube 5, the internal pressure of each group of supporting conical tubes 5 is maintained, and the curved hole 77 in the leveling component 7 that has been leveled is moved into place and connected with the bypass port 9, the internal air pressure of the leveling component 7 is restored, and the leveling block 11 moves up and moves away from the top surface of the thin plate to complete the leveling process, and then the No. 2 electric push rod 32 in the supporting component 3 is started to drive the auxiliary supporting carrier plate 31 to move down, releasing the bottom surface of the thin plate, starting the gantry 14 and moving it, and causing the robot arm cutting end 15 to move, and perform the cutting operation according to the set program.

[0030] Firstly, the initial support for the placement of the thin plate is achieved by utilizing the support component 3 and the support conical tube 5, and in conjunction with the connected suction effect of the negative pressure component 6 and the leveling component 7, after the thin plate is placed, the leveling block 11 which moves downward from the central position moves downward the top surface of the thin plate, and pushes along the horizontal sides to achieve extrusion and leveling of the thin plate, and in conjunction with the reversing suction of the negative pressure component 6, the thin plate is negatively adsorbed and fixed during the leveling process, and after the leveling is completed, the adsorption and fixation after leveling is achieved, and the support component 3 is removed to achieve the bottom array support and adsorption fixation of the support conical tube 5, which greatly improves the three-dimensional laser cutting machine's ability to cope with the cutting processing of ultra-thin metal sheets, avoids local bulging of ultra-thin metal sheets that makes it difficult to cut accurately, and has a good actual leveling effect.

[0031] In addition, by utilizing the negative pressure suction effect of the negative pressure component 6, after leveling is completed, the negative pressure inside the supporting conical tube 5 is treated, and the unified sealing of the sealing component 10 is utilized to seal the multiple groups of supporting conical tubes 5 distributed in the array, and cooperate with the supporting component 3 to achieve support before leveling, and achieve adsorption and fixation after leveling. In fact, the two supporting states are quickly achieved, the support is stable, and the use effect is good.

[0032] Embodiment 2: When cutting, the thin plate product cut from the thin plate is fixed by adsorption through the bottom supporting conical tube 5 to maintain stability. When the locally formed small-sized product is not adsorbed on the top of the supporting conical tube 5, it falls downward to the top of the carrier plate 31. When the cutting is completed, as the carrier plate 31 moves upward, the material falling on the top surface of the carrier plate 31 is pushed upward for unified picking.

[0033] Firstly, by reusing the supporting conical tube 5 and the negative pressure component 6 and cooperating with the sealing component 10 to adsorb, support and fix the sheet, the array distribution and independent sealing effect of each supporting conical tube 5 are utilized, so that the ultra-thin sheet that is partially cut and formed can also be adsorbed and fixed by the corresponding supporting conical tube 5 below after being cut and formed from the sheet to avoid tipping over. During and after the cutting process, stable adsorption support can be maintained to avoid affecting the cutting process when the bottom of the sheet is attached to the support, and to prevent the formed product from falling into the gap. For the smaller-sized products that fall after cutting, the lifting and moving supporting component 3 can also be used to lift and push them upward, which reduces the falling situation and can also achieve rapid separation and picking up for the fallen products, with a good comprehensive use effect.

[0034] Among them, the connecting block 71 is fixedly connected to the curved rod 72, the other end of the curved rod 72 is movably sleeved in the sleeve 73, the sleeve 73 is fixed to the top of the slider 74, the elastic sealing gasket 75 is fixedly connected to the side of the slider 74, the curved hole 77 is opened inside the slider 74 and is connected to the sleeve 73, the spring 76 is located in the sleeve 73, one end of the spring 76 is fixedly connected to the curved rod 72, and the other end is fixed to the top of the slider 74.

[0035] The flattening block 11 is driven downward by the flattening assembly 7 to achieve the compression of the thin plate to be flattened, and the two sets of flattening assemblies 7 move in opposite directions on both sides to push and squeeze the flattening process along the top of the thin plate. The elastic sealing gasket 75 maintains the dynamic seal to ensure that the internal negative pressure space is sealed after moving out of the No. 1 hole 8, and the thin plate is kept pressed downward. The spring 76 is used to restore the internal air pressure and then automatically elastically reset to lift the curved rod 72 and the flattening block 11 upward.

[0036] Among them, the machine frame 2 is fixed on the top of the base 1, the gantry 14 is movably installed on the top of the base 1, the machine arm cutting end 15 is fixed on the gantry 14, and the side of the machine frame 2 is respectively provided with a No. 1 hole 8 and a bypass port 9, and the bypass ports 9 are symmetrically distributed on both sides of the No. 1 hole 8. The number of the No. 1 holes 8 is the same as the number of the slider 74, and the No. 1 hole 8 and the bypass port 9 are both located on the moving path of the curved hole 77.

[0037] The gantry 14 is used to install and support the robot arm cutting end 15. The robot arm cutting end 15 is an existing welding end and can be adjusted within a spatial range to achieve three-dimensional laser cutting processing. When the bypass port 9 is aligned and connected with the curved hole 77, it guides the restoration of the internal air pressure of the leveling component 7.

[0038] Among them, the negative pressure component 6 includes an intermediate frame 61, a vacuum pump 62 and an air pipe 63, the distribution component 4 includes a distribution frame 41 and a through hole 42, the vacuum pump 62 is fixed at the top of the base 1, and a reversing valve is provided at the air outlet end of the vacuum pump 62. The reversing valve has two air outlet ends, one air outlet end is connected to the distribution frame 41, and the other air outlet end is connected to the intermediate frame 61. The air pipe 63 is fixedly connected to both ends of the intermediate frame 61 and is connected to the intermediate frame 61. The other end of the air pipe 63 is connected to the No. 1 hole 8. The through hole 42 is opened at the top of the distribution frame 41, and the through hole 42 is connected to the supporting conical tube 5, and the supporting conical tube 5 is fixed to the top of the distribution frame 41.

[0039] The negative pressure component 6 uses negative pressure suction force to suck the air inside the distribution component 4 upward through the distribution component 4, and suck the air inside the supporting conical tube 5 to achieve negative pressure adsorption. After switching the suction direction, it cooperates with the No. 1 hole 8 to suck the air inside the leveling component 7 to achieve negative pressure control.

[0040] Among them, the supporting assembly 3 includes a carrier plate 31, a No. 2 electric push rod 32 and a top hole 33. The carrier plate 31 is located above the distribution frame 41. The No. 2 electric push rod 32 is fixed to the top surface of the base 1 and is located in the machine frame 2. The movable end of the No. 2 electric push rod 32 is fixedly connected to the carrier plate 31. The top hole 33 is opened at the top of the carrier plate 31. The top hole 33 corresponds one-to-one with the supporting conical tube 5 and is movably sleeved.

[0041] The support component 3 realizes auxiliary support. During the leveling process, it supports and places the thin plate, and moves down and hides during laser welding to avoid laser damage to the top of the support component 3. After cutting, the waste and small-sized cut materials are pushed up through the upward control to achieve quick separation and removal.

[0042] The pushing mechanism includes an electric push rod 12 and a connecting frame 13. The electric push rod 12 is fixed to both ends of the frame 2 through a bracket. The connecting frame 13 is fixedly connected to the movable end of the electric push rod 12. The connecting frame 13 is fixedly connected to the slider 74.

[0043] By using the pushing mechanism to provide a pushing force, the lateral movement control of the leveling assembly 7 is achieved, and the leveling assemblies 7 are controlled to move away from and close to each other.

[0044] A limiting block is provided on the side of the slider 74 , and the slider 74 slides along the top of the base 1 through the limiting block.

[0045] The limit block on the slider 74 provides a piecing and sliding effect to maintain sliding stability and limit the stable movement of the leveling assembly 7 in the horizontal direction.

[0046] Among them, a sealing component 10 is provided in the distribution component 4, and the sealing component 10 includes a sealing plate 101, an intermediate plate 102 and an electric push rod three 103. The sealing plates 101 are arrayed in the distribution frame 41, the intermediate plate 102 is fixed on the bottom surface of the sealing plate 101, and the electric push rod three 103 is fixedly nested on the inner wall of the machine frame 2, and the movable end passes through the distribution frame 41 and is fixedly connected to the intermediate plate 102.

[0047] By utilizing the distribution component 4 to realize the suction of pressurized air, the pressurized air is guided to be sucked inside the supporting conical tube 5, the sealing component 10 realizes internal sealing, and seals each supporting conical tube 5 to ensure that the supporting conical tube adsorbs and fixes the top thin plate. When the top of a group of supporting conical tubes 5 is opened, the other parts still maintain a stable adsorption and fixing effect, especially for small-sized materials cut and formed from the overall thin plate, the adsorption of a single group of supporting conical tubes 5 can also maintain stable fixation.

[0048] The working principle and use process of the present invention are as follows: when in use, the thin plate to be cut is placed on the top surface of the carrier plate 31 of the support assembly 3 and in contact with the top of the supporting conical tube 5, the vacuum pump 62 in the negative pressure assembly 6 is started, and the reversing valve is activated, and the vacuum pump 62 sucks the air inside the middle frame 61, and sucks the air in the leveling assemblies 7 on both sides through the air pipe 63 and the No. 1 hole 8, and sucks the air in the sleeve 73 through the aligned curved holes 77. The air pressure inside the sleeve 73 is reduced, driving the curved rod 72 to move downward, compressing the spring 76, and driving the connecting block 71 and the leveling block 11 to move downward, so that the two leveling assemblies in the middle of the top of the thin plate are compressed. The flat block 11 moves down and contacts and presses on the top surface of the thin plate, and the pushing mechanism is started, so that the electric push rods 12 on both sides respectively drive the leveling components 7 on both sides to move in the opposite direction through the connecting frame 13, so that the two leveling blocks 11 are centered along the top surface of the thin plate and slide toward both sides, pressing the thin plate downward and leveling it. When the leveling component 7 moves away from the No. 1 hole 8, it slides along the side of the machine frame 2 through the elastic sealing gasket 75, and the internal pressure of the leveling component 7 is maintained to maintain the compression and leveling. As the leveling is about to be completed, the reversing valve is actuated, and the vacuum pump 62 directly sucks the air in the distribution frame 41 of the distribution component 4, thereby sucking the connected supporting conical tube 5 When the thin plate is leveled and seals the top of the supporting conical tube 5, the negative pressure inside the supporting conical tube 5 causes the leveled thin plate to be adsorbed and fixed on the top of the supporting conical tube 5. When the leveling is completed, the thin plate is completely adsorbed and fixed on the top of the supporting conical tube 5 distributed in the array. The sealing component 10 is started, and the electric push rod 3 103 drives the sealing plate 101 to move horizontally and cover the bottom connection of the supporting conical tube 5 to maintain the internal pressure of each group of supporting conical tubes 5. The curved hole 77 in the leveling component 7 that has been leveled moves into place and is connected to the bypass port 9. The internal air pressure of the leveling component 7 is restored, and the leveling block 11 moves up and moves away from the top surface of the thin plate. After the leveling process is completed, the No. 2 electric push rod 32 in the support assembly 3 is started, which drives the auxiliary support carrier 31 to move down, releases the bottom surface of the thin plate, starts the gantry 14 and moves it, and makes the robot arm cutting end 15 move to perform the cutting operation according to the set program; when cutting, the thin plate product cut off from the thin plate is adsorbed and fixed by the bottom support conical tube 5 to maintain stability. When the locally formed small-sized product is not adsorbed on the top of the support conical tube 5, it falls downward to the top of the carrier 31. When the cutting is completed, as the carrier 31 moves upward, the material falling on the top surface of the carrier 31 is pushed to the top for unified picking.
