[0021] 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 a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.
[0022] like Figures 1 to 4 As shown, a straightening machine for processing high-strength screw 9 includes a machine body, which includes a first conveyor belt 21, a second conveyor belt 22, a placement platform 3 located between the first conveyor belt 21 and the second conveyor belt 22, a straightening mechanism, a feeding mechanism, and a limiting mechanism.
[0023] The placement platform 3 has a placement rack 31 for placing the screw 9, and the placement rack 31 has a placement groove 32.
[0024] The feeding mechanism includes a feeding frame 41, on which a first guide rail 42 is mounted. A first sliding seat 43 is slidably connected to the first guide rail 42. A first hydraulic cylinder 44 is mounted on the first sliding seat 43. A lifting frame 45 is fixed on the piston rod of the first hydraulic cylinder 44. A second hydraulic cylinder 46 is mounted on the lifting frame 45. A lifting plate 47 is fixed on the piston rod of the second hydraulic cylinder 46. A first mechanical gripper 48 and a second mechanical gripper 49 for clamping the screw 9 are mounted at the bottom of the lifting plate 47.
[0025] The limiting mechanism includes a base 51 symmetrically arranged on both sides of the placement platform 3. A second guide rail 52 is installed on the base 51. A second sliding seat 53 is slidably connected to the second guide rail 52. A lifting rod 54 is fixed on the second sliding seat 53. A first mounting plate 55 is fixed on the lifting rod 54. A third hydraulic cylinder 56 is installed on one side of the mounting plate. A limiting pressure roller 57 is installed on the piston rod of the third hydraulic cylinder 56 to limit the two ends of the screw 9.
[0026] The straightening mechanism includes a straightening table 61, a fourth hydraulic cylinder 62 is mounted on one side of the straightening table 61, a second mounting plate 63 is mounted on the piston rod of the fourth hydraulic cylinder 62, a lifting motor 64 is mounted on the second mounting plate 63, and a straightening component 65 for pressing down and straightening the screw 9 is mounted on the lifting rod 54 of the lifting motor 64.
[0027] In this utility model, the first conveyor belt 21 and the second conveyor belt 22 are existing technologies.
[0028] Using the above structure, the screw 9 is placed on the first conveyor belt 21 for conveying. The first conveyor belt 21 conveys one of the screws 9 to the far right. Then, the first conveyor belt 21 stops conveying. Subsequently, the first sliding seat 43 slides left and right on the first guide rail 42, and the first hydraulic cylinder 44 pushes the lifting frame 45 forward, so that the first mechanical gripper 48 on the lifting plate 47 can be positioned directly above the rightmost screw 9 on the first conveyor belt 21, and the second mechanical gripper 49 is positioned directly above the other screw 9 on the placement slot 32 of the placement platform 3. The second hydraulic cylinder 46... The screw descends, allowing the first mechanical gripper 48 and the second mechanical gripper 49 to reach the screw 9 below it and clamp it. Then, by moving the first sliding seat 43 on the first guide rail 42, the screw 9 on the left side that has not yet been straightened is picked up by the first mechanical gripper 48 and placed in the placement slot 32 of the placement table 3. The screw 9 that has been straightened on the placement table 3 can be picked up by the second mechanical gripper 49 and placed at the leftmost conveying position of the second conveyor belt 22, thus completing the loading and unloading of the screw 9. This helps to improve the efficiency of loading and unloading and automatically performs loading and unloading operations.
[0029] A control panel 7 for control is installed on one side of the straightening table 61.
[0030] After the unstraightened screw 9 is placed into the placement slot 32 of the placement table 3, the first hydraulic cylinder 44 retracts the feeding rack, and simultaneously the piston rod of the fourth hydraulic cylinder 62 on the straightening table 61 moves the second mounting plate 63 backward, causing the straightening component 65 to be adjusted above the screw 9 that needs straightening. The position of the screw 9 that needs straightening is detected by the screw 9 parameters on the control panel 7. The fourth hydraulic cylinder 62 repeatedly moves the second mounting plate 63 forward or backward, and the lifting motor 64 moves the straightening component 65 up or down, thus straightening the screw 9. The screw 9 is straightened at different parts. Before straightening, the second sliding seat 53 on the second guide rail 52 and the third hydraulic cylinder 56 are moved to adjust the limiting pressure rollers 57 on both sides to be directly above the two ends of the screw 9. At the same time, the height of the lifting rod 54 on the second sliding seat 53 is adjusted so that the bottom of the limiting pressure roller 57 can abut against the screw 9 below it. This helps to limit the height of the two ends of the screw 9 before straightening, and automatically straightens it. This prevents the two ends of the screw 9 from tilting up during straightening, resulting in better straightening effect and higher processing quality.
[0031] Specifically, such as Figures 1 to 4 As shown, a controller 491 for controlling the gripping of the mechanical grippers is installed on one side of both the first mechanical gripper 48 and the second mechanical gripper 49.
[0032] With the above structure, by setting the controller 491, it is beneficial to automatically control the first mechanical gripper 48 and the second mechanical gripper 49 to grip or release, and to control them in real time with precision. This makes it easier to grip and place the screw 9, and the gripping effect is better.
[0033] like Figures 1 to 4 As shown, the distance from the rightmost screw 9 position on the first conveyor belt 21 to the placement groove 32 is equal to the distance from the leftmost screw 9 position on the second conveyor belt 22 to the placement groove 32 and the distance between the first mechanical gripper 48 and the second mechanical gripper 49. This design allows screws 9 that have not yet been straightened on the left side to be gripped by the first mechanical gripper 48 and placed in the placement groove 32 of the placement platform 3. For screws 9 that have already been straightened on the placement platform 3, they can be gripped by the second mechanical gripper 49 and placed at the leftmost conveying position of the second conveyor belt 22, completing the loading and unloading of screws 9. This improves the efficiency of loading and unloading, automatically performs loading and unloading operations, and ensures precise loading and unloading.
[0034] like Figures 1 to 4 As shown, the bottom of the limiting pressure roller 57 abuts against the uppermost end of the screw 9. This facilitates the limiting and abutting of both ends of the screw 9, preventing the ends of the screw 9 from tilting up during straightening.
[0035] like Figures 1 to 4As shown, both the first conveyor belt 21 and the second conveyor belt 22 are provided with an array of grooves 8 for securing the screw 9 during conveying. The grooves 8 facilitate the placement of the screw 9 during conveying, ensuring smooth transport and preventing it from falling off the conveyor belt.
