Description

Technical Field

[0001] This utility model belongs to the technical field of center groove alignment machine, specifically a precision alignment machine for center grooves. Background Technology

[0002] As a key load-bearing component of the scraper conveyor, the central trough is prone to problems such as side bending, local bulging, and deformation after long-term exposure to material impact, scraper friction, and stress under complex working conditions. It needs to be corrected and repaired by a straightening machine to restore its performance.

[0003] Currently, existing center slot straightening machines have poor adaptability to fixing mechanisms for center slots of different specifications. Most are rigid structures designed for center slots of specific widths and lengths. When processing center slots of different sizes, multiple positioning components need to be disassembled and replaced, which is cumbersome and time-consuming, seriously affecting straightening efficiency. The adjustment method is also limited, only allowing for rough adjustment in one direction. It cannot be accurately adapted to the actual dimensions of the center slot (such as the width and length of the slot), resulting in insufficient fixing stability. Workpiece displacement is prone to occur during the straightening process, affecting the correction accuracy. Summary of the Invention

[0004] The purpose of this invention is to provide a precise center groove alignment machine to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: This utility model provides a precision correction center groove straightening machine, including a base.

[0017] The present invention will be further described below with reference to the embodiments.

[0018] Example: Refer to Figures 1 to 4 A precision-correcting center groove alignment machine includes a base 1. A multi-directional adaptive adjustment mechanism is located on the top of the base 1, and a clamping mechanism is located above the adaptive adjustment mechanism. Two support rods 18 are provided on each corresponding side of the base 1. Connecting columns 28 are fixedly connected to the ends of the four support rods 18 near the base 1, and the connecting columns 28 are fixedly connected to the base 1. A connecting rod 16 is fixedly connected to the top of every two support rods 18. A threaded rod 15 is rotatably connected to the side of the two connecting rods 16 that is close to each other. A second motor 10 is fixedly connected to one side of one of the connecting rods 16, and the output end of the second motor 10 is fixedly connected to the threaded rod 15. A clamping mechanism is fixedly connected to the side of the two connecting rods 16 that is close to each other and located on both sides of the threaded rod 15. A movable base 12 is provided on the outer side of the limiting rod 14, the threaded rod 15, and the limiting rod 14. A hydraulic drive mechanism 13 is fixedly connected to the top of the movable base 12, and a hydraulic cylinder 11 is fixedly connected to the bottom of the movable base 12. A pressure plate 9 is provided at the output end of the hydraulic cylinder 11. The hydraulic cylinder 11 and the pressure plate 9 are fixedly connected by bolts. A telescopic base mechanism is provided on the top of the base 1. Through the coordination of the multi-directional adaptive adjustment mechanism, the clamping mechanism and the telescopic base mechanism, it can adapt to the central slot of different specifications. The motor 10 drives the threaded rod 15 to cooperate with the limiting rod 14 to realize the smooth movement of the movable base 12. Combined with the precise force application of the hydraulic cylinder 11 and the pressure plate 9, the calibration accuracy and efficiency are greatly improved, solving the problems of poor adaptability and cumbersome adjustment of traditional equipment.

[0019] The adaptive adjustment mechanism includes two slots 26, which are located on both sides of the top of the base 1. A double-acting lead screw 29 is rotatably connected inside the slot 26. Slider 27s are threaded onto the outer sides of the double-acting lead screw 29 at both corresponding ends. A slide rail 6 is fixedly connected to the top of each pair of sliders 27. A slot 4 is provided on one side of the slide rail 6. A double-acting lead screw 5 is rotatably connected inside the slot 4. Slider 2s are threaded onto the outer sides of the double-acting lead screw 5 at both corresponding ends. Two motors 3 are fixedly connected to one side of the base 1. The output end is fixedly connected to the bidirectional lead screw 29. Motor 30 is fixedly connected to one side of each of the two slide rails 6. The output end of motor 30 is fixedly connected to the bidirectional lead screw 5. Motor 3 drives the bidirectional lead screw 29 to rotate, which drives the slider 27 and slide rail 6 to move laterally along the groove 36. Motor 30 drives the bidirectional lead screw 5 to drive the slider 2 to adjust longitudinally along the groove 4. This achieves multi-dimensional and precise adaptation to the middle grooves of different widths and lengths without disassembling components. The adjustment efficiency is improved by more than 50%, solving the problems of single adjustment and poor adaptability of traditional equipment.

[0020] The clamping mechanism includes four limiting blocks 21. The limiting blocks 21 are fixedly connected to one side of the slider 2 and located above the slide rail 6. The limiting blocks 21 are internally threaded with screws 31. The top of the screws 31 is fixedly connected with a rotating handle 32. The bottom of the screws 31 and located inside the limiting blocks 21 is fixedly connected with a clamping plate 25. By rotating the handle 32, the screws 31 are driven to move the clamping plate 25 up and down, which can precisely adjust the clamping force. This avoids the problem of the clamping force being too loose, which would cause the middle groove to shift during the alignment process, and also prevents the clamping force from being too tight, which would cause damage to the groove. The fixing stability is improved by 40%, solving the problem of uncontrollable force in traditional fixing mechanisms.

[0021] The telescopic base mechanism includes a pressure platform 17, which is fixedly connected to the top of the base 1. The pressure platform 17 has slots 23 on both sides. Springs 24 are provided inside the slots 23 and on the corresponding sides. An extension platform 8 is slidably connected inside the slots 23. The springs 24 are fixedly connected to the extension platform 8. The extension platform 8 can slide along the slots 23 to adapt to the middle slots of different lengths. The buffering effect of the springs 24 can reduce the vibration and impact during the calibration, improve the support stability, and avoid calibration deviations caused by improper support. The adaptable length range is expanded to 1.5 times that of traditional equipment.

[0022] The movable base 12 is slidably connected to the limit rod 14 and the threaded rod 15 respectively. The slider 1 2 is slidably connected to the slot 1 4, and the slider 2 27 is slidably connected to the slot 3 26. The cooperation between the sliding connection and the threaded connection ensures that the movable base 12, slider 1 2, and slider 2 27 move smoothly without jamming. The adjustment accuracy can reach ±0.5mm, avoiding the calibration error caused by component jamming and extending the service life of the equipment by more than 30%.

[0023] One of the support rods 18 is fixedly connected to a control panel 7. Motor 1 3, Motor 2 10, and Motor 3 30 are all electrically connected to the control panel 7. The control panel 7 realizes the linkage control of Motor 1 3, Motor 2 10, and Motor 3 30. Operators can complete the adjustment and calibration operation with one button, reducing manual intervention, reducing labor intensity, and ensuring operation consistency.

[0024] The working principle of this utility model is as follows: In use, the central groove to be corrected is first placed on the pressure platform 17. At this time, the extension platform 8 of the telescopic base mechanism slides along groove 23 to adapt to the length of the central groove. The spring 24 extends and retracts with the movement of the extension platform 8, providing buffer support. The motor 3 is started via the control panel 7. The output end of the motor 3 drives the bidirectional lead screw 29 to rotate within groove 3 26. The slider 27 on the outer side of the bidirectional lead screw 29 slides along groove 3 26, causing the top-fixed slide rail 6 to move laterally, adjusting the distance between the two slide rails 6 to adapt to the width of the central groove. Next, the motor 30 is started via the control panel 7. The output end of the motor 30 drives the bidirectional lead screw 5 to rotate within groove 4. The slider 2 on the outer side of the bidirectional lead screw 5 moves longitudinally along groove 4, causing the slider 2... 2. Align the limiting block 21 on one side with the two sides of the central groove, rotate the rotating handle 32, and the screw 31 rotates in the thread of the limiting block 21, driving the clamping plate 25 to move downward and clamp the central groove. Then, start the second motor 10 through the control panel 7. The output end of the second motor 10 drives the threaded rod 15 to rotate between the two connecting rods 16. The movable base 12, which is threaded to the threaded rod 15, slides along the limiting rods 14 on both sides, driving the hydraulic cylinder 11 and the pressure plate 9 at the bottom to move to the position of the central groove that needs to be corrected. Finally, start the hydraulic drive mechanism 13. The output end of the hydraulic cylinder 11 pushes the pressure plate 9 to apply pressure to the deformed part of the central groove for correction. The entire process is controlled by the control panel 7 to realize the linkage control of the first motor 3, the second motor 10, the third motor 30 and the hydraulic drive mechanism 13, and complete the precise correction operation.
