Description

Technical Field

[0001] This invention relates to the field of steel plate processing for engineering machinery, specifically to a steel plate twisting and leveling machine and a leveling method for engineering machinery. Background Technology

[0002] Lightweight design has been widely applied in aerospace, automotive, and electronics industries, but in China's construction machinery and vehicle sector, especially for construction cranes, this field is still in its infancy. Achieving lightweighting of the core component of construction cranes—the boom—can significantly reduce the crane's workload, increase rated power, and achieve a leap in equipment performance. Using high-strength, high-toughness steel plates with good mechanical and performance properties can effectively reduce the weight of the construction crane boom, achieving the goal of lightweighting.

[0003] When processing and producing steel plates for construction machinery, in order to ensure that the surface tilt of the finished product does not have a large deviation, the steel plates for construction machinery are usually twisted and leveled. Most existing twisting and leveling machines clamp and fix one end of the steel plate, then hold the other end of the steel plate tightly, and then slowly twist the steel plate so that the steel plate can be leveled during the twisting process.

[0004] However, existing twisting and leveling machines mostly require manual observation to ensure the steel plate is completely level. Furthermore, when correcting the twist, manual adjustment of the force points is necessary, consuming significant manpower and hindering processing efficiency. Additionally, if localized twisting occurs at the clamping points of the steel plate, operators must tap and flatten these points, which is time-consuming and labor-intensive.

[0005] In contrast, it is necessary for us to design an engineering machinery steel plate twisting and leveling machine and provide a corresponding leveling method. Summary of the Invention

[0006] Therefore, it is necessary to provide an engineering machinery steel plate twisting and leveling machine and leveling method to address the existing technical problems.

[0017] Furthermore, the adjustment mechanism also includes an anti-reverse bracket, an anti-reverse pin, a return spring, an anti-reverse rod, and a ratchet. The anti-reverse bracket is fixedly connected to the end of the rotating gear ring away from the positioning bearing box. The anti-reverse pin is slidably connected to the upper end of the anti-reverse bracket. The anti-reverse rod is fixedly connected to the end of the anti-reverse pin away from the anti-reverse bracket. The return spring is sleeved on the outside of the anti-reverse pin, with one end abutting against the anti-reverse bracket and the other end abutting against the anti-reverse rod. The ratchet is located at the end of the anti-reverse rod away from the anti-reverse bracket and abuts against the anti-reverse rod. The ratchet is coaxially arranged with the adjustment handle.

[0025] S3: After the steel plate is twisted and leveled for the first time, the operator starts the dual-head motor to move the steel plate. After the distance the steel plate moves is recorded by the distance measuring grating, the two distance measuring sensors will detect both sides of the steel plate and select whether to continue twisting and leveling based on the offset parameters of the steel plate.

[0040] To further understand the features, technical means, and specific objectives and functions achieved by the present invention, the present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments.

[0041] refer to Figures 1 to 8 A steel plate twisting and leveling machine for engineering machinery, comprising:

[0042] Support bracket 1 is set in a horizontal position;

[0043] The ranging grating 2 is installed at the upper end of the support frame 1;

[0044] Support plate 4 is set on the side of support frame 1 and is set in a horizontal position;

[0045] Two ranging sensors 3 are horizontally positioned on the upper end of the support frame 1, near the support plate 4.

[0046] The positioning and clamping assembly 36 is located on the upper end of the support plate 4 near the support frame 1. It includes a positioning support box 38, a second sensor 40, a clamping cylinder 37, and a clamping mechanism 41. The positioning support box 38 is fixedly connected to the support plate 4. The second sensor 40 is located on the side of the positioning support box 38 away from the support frame 1. The clamping cylinder 37 is vertically located inside the positioning support box 38. The clamping mechanism 41 is located at the upper end of the clamping cylinder 37 and is connected to the output end of the clamping cylinder 37.

[0047] The torsion clamping assembly 5 is located on the upper end of the support plate 4 away from the support frame 1. It includes a sliding bearing box 6, a dual-head motor 7, a power motor 8, a first sensor 9, an adjustment mechanism 16, an adaptive clamping mechanism 32, and two support brackets 12. The sliding bearing box 6 is slidably disposed on the upper end of the support plate 4. The first sensor 9 is disposed on the side of the sliding bearing box 6 near the positioning bearing box 38. The second sensor 40 is electrically connected to the first sensor 9. The dual-head motor 7 is disposed inside the sliding bearing box 6. The two support brackets 12 are symmetrically disposed on the upper end of the sliding bearing box 6. The power motor 8 is fixedly connected to one support bracket 12 through a motor frame. The adjustment mechanism 16 is disposed between the two support brackets 12. The adjustment mechanism 16 includes an adjustment handle 24. The adaptive clamping mechanism 32 is connected to the adjustment handle 24. The adjustment mechanism 16 can drive the adaptive clamping mechanism 32 to clamp the steel plate.

[0048] When the steel plate is twisted and leveled, the operator first starts the clamping cylinder 37 to clamp one end of the steel plate, and then turns the adjusting handle 24 to drive the adaptive clamping mechanism 32 to clamp the other end of the steel plate. Then the operator starts the power motor 8 to drive the other end of the steel plate to twist. During this process, the twisted steel plate will be leveled. The specific twisting process of the steel plate will be explained later. After the initial leveling, the operator starts the dual-head motor 7 to move the sliding support box 6 towards the positioning support box 38. During this process, the end of the steel plate away from the sliding support box 6 extends into the ranging grating 2. The ranging grating 2 can detect the distance the steel plate moves and record this distance through the controller. Then, the two ranging sensors 3 set on the upper end of the support frame 1 will detect the steel plate being twisted and leveled. After detecting the offset on both sides of the steel plate, if the offset on both sides of the steel plate meets the error requirements, the steel plate completes the twisting and leveling work. If the offset on both sides of the steel plate does not meet the error requirements, the sliding support box 6 moves away from the positioning support box 38. Then, the first sensor 9 and the second sensor 40 adjust the distance between the sliding support box 6 and the positioning support box according to the data recorded in the controller, thereby controlling the position of the force point for the next twisting and leveling, which facilitates the subsequent twisting and leveling work. The above steps are repeated until the offset on both sides of the steel plate meets the processing requirements.

[0049] To improve the stability of the sliding bearing box 6 during movement, the following features are specifically designed:

[0050] The torsion clamping assembly 5 also includes two sliding racks 10 and two sliding gears 11. The two sliding gears 11 are connected to the two ends of the dual-head motor 7 via keys, and the two sliding racks 10 mesh with the two sliding gears 11. After the dual-head motor 7 is started, the two sliding gears 11 rotate, and this rotation drives the sliding support box 6 to move along the sliding racks 10 towards the positioning support box 38. During this process, the meshing of the two sliding gears 11 and the two sliding racks 10 improves the stability of the movement of the sliding support box 6.

[0051] In order to provide output power for the twisting and leveling of the steel plate, the following features are specifically designed:

[0052] The torsion clamping assembly 5 also includes a drive gear 14 and a reduction gear 15. The adjustment mechanism 16 also includes a rotating gear ring 17. The support bracket 12 is formed with an anti-detachment groove 13. The rotating gear ring 17 is formed with anti-detachment flanges 18 on both sides. The drive gear 14 is keyed to the output end of the power motor 8. The reduction gear 15 is located beside the drive gear 14 and meshes with it. The rotating gear ring 17 is rotatably arranged coaxially with the upper ends of the two support brackets 12. The anti-detachment flanges 18 on both sides of the rotating gear ring 17 are slidably connected to the anti-detachment grooves 13 on the two support brackets 12 respectively. The rotating gear ring 17 and the reduction gear 15 mesh with each other. After the power motor 8 is started, the power motor 8 will drive the drive gear 14 to rotate. The rotation of the drive gear 14 will drive the reduction gear 15 meshing with it to rotate. The rotation of the reduction gear 15 will drive the rotating gear ring 17 meshing with it to rotate. The rotation of the rotating gear ring 17 will serve as the power source for the steel plate torsion leveling. During this process, the sliding connection between the anti-detachment flange 18 and the anti-detachment groove 13 can improve the stability of the rotating gear ring 17 when it rotates.

[0053] To prevent the steel plate from slipping during rotation, the following features are specifically designed:

[0054] The adjustment mechanism 16 also includes an anti-reverse bracket 19, an anti-reverse pin 20, a return spring 21, an anti-reverse rod 22, and a ratchet 23. The anti-reverse bracket 19 is fixedly connected to the end of the rotating gear ring 17 away from the positioning bearing box 38. The anti-reverse pin 20 is slidably connected to the upper end of the anti-reverse bracket 19. The anti-reverse rod 22 is fixedly connected to the end of the anti-reverse pin 20 away from the anti-reverse bracket 19. The return spring 21 is sleeved on the outside of the anti-reverse pin 20. One end of the return spring 21 abuts against the anti-reverse bracket 19, and the other end abuts against the anti-reverse rod 22. The ratchet 23 is located at the end of the anti-reverse rod 22 away from the anti-reverse bracket 19 and abuts against the anti-reverse rod 22. The ratchet 23 is coaxially arranged with the adjustment handle 24. When the rotating gear ring 17 rotates, in order to prevent the end of the steel plate that is clamped from slipping under the action of centrifugal force, after the steel plate is clamped, the anti-reverse insertion rod 22 abuts against the ratchet 23 under the action of the return spring 21. The anti-reverse insertion rod 22 can ensure that the ratchet 23 rotates in only one direction. When resetting, the operator needs to push the anti-reverse insertion rod 22 in the opposite direction to ensure that the ratchet 23 can rotate in the opposite direction.

[0055] In order to clamp the steel plate and allow the clamped point of the steel plate to rotate, the following features are specifically designed:

[0056] The adjustment mechanism 16 also includes a drive pin 25, a first bevel gear 26, a second bevel gear 27, an adjustment gear 28, a drive gear 29, a two-way lead screw 30, and four limiting long shafts 31. The upper end of the drive pin 25 is keyed to the adjustment handle 24, and the middle end of the drive pin 25 is keyed to the ratchet 23. The first bevel gear 26 is keyed to the lower end of the drive pin 25. The second bevel gear 27 meshes with the first bevel gear 26. The adjustment gear 28 is keyed to the second bevel gear 27 along the same axis. The drive gear 29 is located beside the adjustment gear 28 and meshes with it. The two-way lead screw 30 is keyed to the drive gear 29 along the same axis. The four limiting long shafts 31 are arranged in pairs on both sides of the rotating gear ring 17. The pair of limiting long shafts 31 on the same side are arranged symmetrically and fixed to the rotating gear ring 17 by a bracket. After the operator rotates the adjustment handle 24, the rotation of the adjustment handle 24 will drive the drive pin 25 connected to it to rotate. When the drive pin 25 rotates, it will be limited by the ratchet 23. The rotation of the drive pin 25 will drive the first bevel gear 26 connected to it to rotate. The rotation of the first bevel gear 26 will drive the second bevel gear 27 meshing with it to rotate. The rotation of the second bevel gear 27 will drive the adjustment gear 28 connected to it to rotate. The rotation of the adjustment gear 28 will drive the drive gear 29 meshing with it to rotate. The rotation of the drive gear 29 will drive the bidirectional lead screw 30 connected to it to rotate. The rotation of the bidirectional lead screw 30 will cause the end of the steel plate away from the positioning bearing box 38 to be clamped. The specific clamping process will be explained later.

[0057] To prevent slippage at the clamping point of the steel plate, the following features are specifically designed:

[0058] The adaptive clamping mechanism 32 includes four sliding baffles 33 and two supporting sliders 34. The four sliding baffles 33 are arranged in pairs on both sides of the rotating gear ring 17. The two sliding baffles 33 on the same side are slidably connected to the limiting long shaft 31 by brackets. The two sliding baffles 33 on the side of the rotating gear ring 17 away from the positioning bearing box 38 are also threadedly connected to the bidirectional lead screw 30 by brackets. The two supporting sliders 34 are arranged symmetrically in the horizontal direction, and their sides are fixedly connected to the four sliding baffles 33. When the bidirectional lead screw 30 rotates, the four sliding baffles 33, which are threadedly connected to the bidirectional lead screw 30 by supports, can move. The movement of the four sliding baffles 33 will drive the two supporting sliders 34 to move, and the movement of the supporting sliders 34 can adaptively clamp the steel plate.

[0059] To accommodate potential twisting or skewing of the steel plate, the following features are specifically designed:

[0060] The adaptive clamping mechanism 32 also includes several groups of adaptive arc blocks 35 of different sizes. The two largest adaptive arc blocks 35 are slidably connected to the two supporting sliders 34 respectively, and adjacent adaptive arc blocks 35 are slidably connected to each other. The smallest adaptive arc blocks 35 abut against the sides of the steel plate. In order to better exert force when clamping the steel plate, the adaptive arc blocks 35 that are in contact with the steel plate will shift when clamping the steel plate, thereby adapting to the possible twisting slope of the steel plate.

[0061] In order to clamp the other end of the steel plate, the following features are specifically designed:

[0062] The positioning bearing box 38 has a limiting groove 39 formed inside. The clamping mechanism 41 includes a sliding wedge 42, two clamping wedges 44, two jaws 47, and two anti-slip pads 48. The sliding wedge 42 has sliding flanges 43 formed on both sides. The two clamping wedges 44 have sliding grooves 45 formed at one end near the sliding wedge 42. The sliding flanges 43 and sliding grooves 45 are slidably connected. The two clamping wedges 44 have limiting flanges 46 formed at both ends. The limiting flanges 46 and limiting grooves 39 are slidably connected. When the clamping cylinder 37 is activated, the sliding wedge 42 will move, and the two clamping wedges 44 slidably connected to the sliding wedge 42 will move. The two jaws 47 connected to the two clamping wedges 44 will clamp the steel plate. During the clamping process, the two anti-slip pads 48 can increase the coefficient of friction and prevent the steel plate from slipping during clamping.

[0063] A leveling method for a steel plate twisting and leveling machine for engineering machinery also includes the following steps:

[0064] S1: The operator first starts the clamping cylinder 37 to clamp one end of the steel plate, and then turns the adjusting handle 24 to clamp the other end of the steel plate.

[0065] S2: After the two ends of the steel plate are clamped, the operator starts the power motor 8 to drive the steel plate to twist and level it.

[0066] S3: After the steel plate is twisted and leveled for the first time, the operator starts the dual-head motor 7 to move the steel plate. After the distance the steel plate moves is recorded by the ranging grating 2, the two ranging sensors 3 will detect both sides of the steel plate and select whether to continue twisting and leveling according to the offset parameters of the steel plate.

[0067] The working principle of this device is as follows: When the steel plate is twisted and leveled, the operator first starts the clamping cylinder 37. After the clamping cylinder 37 is started, it will drive the two grippers 47 to move and clamp one end of the steel plate. Then the operator turns the adjusting handle 24. After the adjusting handle 24 is turned, it will drive several adaptive arc blocks 35 to approach and clamp the other end of the steel plate. When both ends of the steel plate are clamped, the operator starts the power motor 8. After the power motor 8 is started, it will drive the other end of the steel plate to twist. During this process, the twisted steel plate will be leveled.

[0068] After the initial leveling, the operator starts the dual-head motor 7. The motor 7 then moves the sliding support box 6 towards the positioning support box 38. During this process, the end of the steel plate furthest from the sliding support box 6 extends into the ranging grating 2. The ranging grating 2 detects the distance the steel plate moves and records this distance through the controller. Then, two ranging sensors 3 mounted on the upper part of the support frame 1 detect the steel plate being twisted and leveled. If the offset on both sides of the steel plate meets the error requirements, the twisting and leveling process is complete. If the offset does not meet the error requirements, the sliding support box 6 moves away from the positioning support box 38. Then, the first sensor 9 and the second sensor 40 adjust the distance between the sliding support box 6 and the positioning support box based on the data recorded in the controller, thereby controlling the position of the application point for the next twisting and leveling operation, facilitating subsequent twisting and leveling work. This process is repeated until the offset on both sides of the steel plate meets the processing requirements.

[0069] The above embodiments only illustrate one or more implementations of the present invention, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this patent should be determined by the appended claims.
