[0001] This invention relates to the field of beveling technology, and more specifically, to a thick plate adaptive vertical compensation plasma beveling system. Background Technology

[0002] When butt welding thick steel plates, the roughness of the plate ends and thermal deformation can easily lead to incomplete fusion defects in the middle and root of the weld, necessitating the cutting of the steel plate into bevels before welding.

[0042] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0043] Reference Figures 1 to 11 This embodiment discloses a thick plate adaptive vertical compensation plasma beveling system, including an inclined operating table 1. The operating table 1 includes an inclined frame 11. The inclined frame 11 has an inclination angle of 5°-45° in both the horizontal and vertical directions on the horizontal plane, so that the thick plate can slide freely for unloading after cutting, eliminating the need for secondary handling by workers and reducing labor intensity. The inclined frame 11 is provided with a slag discharge hole 12 and an arc-shaped groove 13. An extension plate 14 is installed parallel to one end of the inclined frame 11 to further assist the sliding of the material plate. Support plates 15 are fixedly installed on both sides of the inclined frame 11. The support plates 15 are located on the lower side of the inclined frame 11 and are perpendicular to the inclined frame 11. The support plates 15 are provided with a first guide groove 16, a first reversing groove 17 and a second guide groove 18 that are connected end to end. The first guide groove 16 and the second guide groove 18 are both perpendicular to the table surface of the inclined frame 11. An arc-shaped rod 19 is fixedly installed at the bottom of the inclined frame 11.

[0044] Reference Figure 1 , Figures 6 to 8 A dual-axis manipulator 2 is installed on the tilting frame 11. The dual-axis manipulator 2 includes an electric slide table 21 installed parallel to the tilting frame 11 and a lead screw slide table 22 installed perpendicular to the tilting frame 11. The lead screw slide table 22 is installed at the output end of the electric slide table 21. The electric slide table 21 is located above the tilting frame 11, that is, there is a certain gap between the bottom of the electric slide table 21 and the table surface of the tilting frame 11 to ensure that the material plate does not collide with the electric slide table 21 when it slides down. A first laser sensor 23 is fixedly installed at the output end of the lead screw slide table 22 to measure the thickness of the material plate placed on the tilting frame 11, thereby controlling the subsequent cutting height adjustment and realizing adaptive vertical compensation of the cutting height when cutting material plates of different thicknesses. The detection direction of the first laser sensor 23 is perpendicular to the table surface of the tilting frame 11.

[0045] A cutting assembly 3 is installed at the output end of the lead screw slide 22. The cutting assembly 3 includes a gas guide rod 31 connected to the plasma equipment. A nozzle 32 is installed at the bottom of the gas guide rod 31. The nozzle 32 is located inside the slag discharge hole 12 to prevent the tilting frame 11 from being damaged or fused and stuck to the material plate due to the high temperature of cutting. A support frame 33 is fixedly installed on the gas guide rod 31. The support frame 33 is set parallel to the axis of the gas guide rod 31. The support frame 33 is rotatably connected to the output end of the lead screw slide 22. The rotation axis of the support frame 33 is equal to the height of the bottom of the nozzle 32. This allows the nozzle 32 to only change its angle when the gas guide rod 31 is rotated to adjust the cutting angle of the bevel, while its height remains at the same position, improving the accuracy of the cutting height positioning. A groove 34 is opened on the support frame 33, and an adjusting rod 35 is slidably connected in the groove 34.

[0046] The cutting assembly 3 also includes a threaded rod 36 screwed to the output end of the lead screw slide 22. The axis of the threaded rod 36 is parallel to the table surface of the tilting frame 11. A connecting block 37 is rotatably connected to the end of the threaded rod 36, and an adjusting rod 35 is rotatably connected to the connecting block 37. By controlling the rotation of the threaded rod 36, the cutting angle of the nozzle 32 can be controlled to achieve cutting of different bevel angles.

[0047] Reference Figure 1 , Figure 3 , Figure 9 and Figure 10 The cutting system also includes a lifting platform 4, which includes a motor 41 fixedly mounted on a support plate 15 via a connecting plate. A lead screw 42 rotatably connected to the tilting frame 11 is fixedly mounted on the output end of the motor 41. A lifting plate 43 parallel to the tilting frame 11 is screwed onto the lead screw 42. The lifting plate 43 is slidably connected to a first guide rod 44 fixedly mounted on the tilting frame 11. Both the lead screw 42 and the first guide rod 44 are perpendicular to the table surface of the tilting frame 11, so that the lifting plate 43 always remains parallel to the table surface of the tilting frame 11 when it is raised and lowered. A through hole 45 is provided on the lifting plate 43 to assist in slag discharge.

[0048] A first limiting component 5 is installed on the lifting plate 43. The first limiting component 5 includes a lifting rod 51 and a limiting plate 52 that are slidably connected to the lifting plate 43 via a guide rail. The two ends of the lifting rod 51 are respectively inserted into the corresponding support plate 15 and move within the first guide groove 16, the first reversing groove 17, or the second guide groove 18. A second guide rod 53 is fixedly installed below the limiting plate 52. The limiting plate 52 is slidably connected to the lifting rod 51 via the second guide rod 53. A first elastic element 54 is fitted on the second guide rod 53. One end of the first elastic element 54 is fixedly connected to the lifting rod 51, and the other end is fixedly connected to the limiting plate 52. The first elastic element 54 is used to push the limiting plate 52 away from the lifting rod 51. Limiting blocks 55 are fixedly installed at both ends of the limiting plate 52 to limit the lifting plate 52 to a set height. When the lifting rod 51 moves within the first guide groove 16, the positional relationship between the limiting plate 52 and the slag discharge hole 12 is as follows. Figure 3 As shown, when the lifting rod 51 moves within the second guide groove 18, the positions of the limiting plate 52 and the slag discharge hole 12 are as follows: Figure 2 As shown, when the lifting rod 51 moves within the first reversing groove 17, it is an adjustment process for the cutting position of the material plate, thereby adapting to the cutting of defects such as pits or protrusions on the edge of the material plate, further improving the flexibility of bevel cutting. Moreover, when the lifting rod 51 moves to the inlet of the first reversing groove 17, the limiting plate 52 has already passed through the slag discharge hole 12. To reduce the difficulty of the limiting plate 52 moving towards the nozzle 32 after reaching the upper limit in the height direction, ball bearings can be set on the top of the limiting block 55 to assist the movement and reduce the movement resistance.

[0049] Reference Figure 4 and Figure 5 A second limiting component 6 is installed on the tilting frame 11. The second limiting component 6 includes an adjusting column 61 rotatably connected to the tilting frame 11 and a second elastic element 63 fitted on the arc-shaped rod 19. The adjusting column 61 is set perpendicular to the platform of the tilting frame 11. The center of the arc of the arc-shaped rod 19 and the center of the arc-shaped groove 13 are both on the axis of the adjusting column 61. A positioning plate 62 is fixedly installed on the adjusting column 61. The positioning plate 62 passes through the arc-shaped groove 13. One end of the second elastic element 63 is fixedly connected to the tilting frame 11, and the other end is fixedly connected to the positioning plate 62. It is used to push the positioning plate 62 to keep it perpendicular to the limiting plate 52. A third guide groove 64 and a second reversing groove 65 connected end to end are opened on the adjusting column 61.

[0050] The lifting plate 43 is fixedly installed with a first lever 7 and a second lever 9 on both sides. The first lever 7 is inserted into the third guide groove 64 or the second reversing groove 65 to move and control the rotation of the adjusting column 61. When the adjusting column 61 rotates, it drives the positioning plate 62 to rotate, thereby adjusting the included angle between the positioning plate 62 and the limiting plate 52 so that it can adapt to the positioning of the double sides of the non-right angle material plate and avoid the problem of inaccurate positioning caused by the tilt angle of the tilting frame 11.

[0051] Reference Figure 3 and Figure 10 A ranging assembly 8 is installed on the tilting frame 11. The ranging assembly 8 includes a rotating column 81 rotatably connected to the tilting frame 11. The rotating column 81 is set perpendicular to the platform of the tilting frame 11. A second laser sensor 82 is fixedly installed on the rotating column 81 for ranging. A fourth guide groove 83, a third reversing groove 84, and a fifth guide groove 85 are opened on the rotating column 81. A second lever 9 is inserted into the fourth guide groove 83, the third reversing groove 84, or the fifth guide groove 85 to move and control the rotation of the rotating column 81 and the second laser sensor 82. The highest point of the third reversing groove 84 is lower than the lowest point of the second reversing groove 85, so that the rotating column 81 rotates before the adjusting column 61 rotates. The lowest point of the third reversing groove 84 is higher than the highest point of the first reversing groove 17. When the second lever 9 is in the fourth guide groove 83, the detection direction of the second laser sensor 82 is perpendicular to the limiting plate 52. When the second lever 9 is in the fifth guide groove 85, the detection direction of the second laser sensor 82 is towards the positioning plate 62. Figure 11 The displacement H of the positioning plate 62 is obtained by the second laser sensor 82. Then, combined with the distance L between the second laser sensor 82 and the adjusting column 61 along the conveying direction, the deflection angle of the positioning plate 62 is obtained according to the tan function, so as to satisfy the positioning of the side of the material plate that is not perpendicular.

[0052] Reference Figure 1 Several cylinders 10 are fixedly installed on the tilting frame 11, and pressure rods 20 for clamping and fixing the material plate are fixedly installed at the output end of the cylinders 10.

[0053] Working principle: The lifting platform 4 drives the lifting rod 51 and the limiting plate 52 to rise. When the lifting rod 51 moves to the end of the first guide groove 16, the limiting plate 52 is stopped in the height direction. The lifting rod 51 continues to move from the first guide groove 16 to the end of the first reversing groove 17. The limiting plate 52 reaches the default cutting position. During this process, the lifting rod 51 slides on the lifting plate 43. The material plate is placed on the inclined frame 11. The side to be cut abuts against the limiting plate 52, and the side with the lower height abuts against the positioning plate 62. After positioning is completed, the output end of the cylinder 10 drives the pressure rod 20 to descend and press and fix the material plate. The lifting platform 4 drives the first limiting component 5 to descend, so that the limiting plate 52 is disengaged and reset.

[0054] The rotating threaded rod 36 pushes the adjusting rod 35 to slide on the support frame 33, thereby driving the air guide rod 31 to rotate, realizing the adjustment of the cutting angle of the nozzle 32 to the bevel. The first laser sensor 23 obtains the thickness of the material plate. The dual-axis robot 2 moves laterally and adjusts the cutting height of the nozzle 32 to realize adaptive cutting of the bevel of the material plate. After cutting, the pressure rod 20 rises and resets. The material plate automatically slides down under the action of the tilting frame 11 and its own weight, realizing unloading.

[0055] When the bevel edge of the material plate is not at a right angle to the adjacent edge, the lifting platform 4 drives the lifting rod 51 to move to the first end of the second guide groove 18. At this time, the second lever 9 enters the first end of the third reversing groove 84, and the first lever 7 is still in the third guide groove 64. When it continues to move upward, the second lever 9 drives the rotating column 81 to rotate. The detection direction of the second laser sensor 82 changes from the limiting plate 52 to the positioning plate 62. The lifting platform 4 drives the lifting rod 51 to continue to rise. The second lever 9 moves into the fifth guide groove 85, and the first lever 7 moves into the second reversing groove 65, driving the adjusting column 61 and the positioning plate 62 to rotate. With the measurement of the second laser sensor 82, the rotation angle of the positioning plate 62 is controlled to achieve the side positioning of the material plate that is not at a right angle.
