Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of steel strip shearing and welding equipment, specifically a positioning structure for an automatic steel strip shearing and welding machine. Background Technology
[0002] On the steel strip production line, the shearing and welding machine is an important piece of equipment to ensure continuous production. The main function of the shearing and welding machine is to weld the ends of two steel coils together so that continuous production can be carried out without stopping the machine. The stability of the positioning structure will affect whether the shearing of the steel strip is flat and whether the welding is aligned.
[0003] Currently, steel strip shearing and welding machines require manual alignment to ensure a smooth cut when shearing steel strips. After the cut is smooth, workers then align the two sides of the cut and weld them together. This process is overly reliant on manual operation, and manual operation is prone to errors. Therefore, it is necessary to propose a positioning structure for an automatic steel strip shearing and welding machine. Utility Model Content
[0004] To overcome the shortcomings of existing technologies, the positioning process of steel strip shearing and welding machines relies too heavily on manual labor, leading to wasted manpower and errors. This utility model proposes a positioning structure for an automatic steel strip shearing and welding machine.
[0005] The technical solution adopted by this utility model to solve its technical problem is: a positioning structure for an automatic steel strip shearing and welding machine, including a fixed frame, a slide table slidably connected to both sides of the inner cavity of the fixed frame, a double sliding mechanism movably installed at the bottom of the slide table, a through groove opened on one side of the slide table, a clamping and limiting mechanism movably installed inside the through groove, a support frame fixedly connected to the top of the slide table, a hydraulic cylinder fixedly installed on the top of the support frame, and a pressure plate fixedly connected to the end of the telescopic shaft of the hydraulic cylinder;
[0006] The clamping and limiting mechanism includes a second motor, which is fixedly installed at the top of the inner cavity of the through groove. Sliders are slidably installed on both sides of the through groove. The second motor slides in cooperation with the sliders. A guide rod is fixedly connected to the top of the slider. Guide posts are fixedly connected to both ends of the top of the guide rod. A guide groove is opened on the top of the slide table. The guide posts slide in cooperation with the guide groove. The double sliding mechanism includes a first motor, which is fixedly installed on one side of the fixed frame. A double threaded rod is fixedly connected to the output end of the first motor. A threaded sleeve is threadedly connected to the outer wall of the double threaded rod. The threaded sleeve is fixedly connected to the bottom of the slide table.
[0007] Preferably, a gear is fixedly connected to the output end of the second motor, and a rack is fixedly connected to the opposite side of the slider, with the gear meshing with the rack.
[0008] Preferably, slide rods are fixedly connected to both sides of the inner cavity of the through groove, and the slider is slidably connected to the top of the slide rods.
[0009] Preferably, the double-threaded rod is rotatably mounted on the bottom of the fixed frame, and a limiting sleeve is rotatably mounted on the middle of the outer wall of the double-threaded rod, and the limiting sleeve is fixedly connected to the bottom of the fixed frame.
[0010] Preferably, the inner wall of the limiting sleeve is continuously provided with limiting grooves, a limiting ring is rotatably connected in the limiting grooves, and the outer wall of the limiting ring is fixedly connected to the double threaded rod.
[0011] Preferably, the bottom of the limiting sleeve is rotatably connected to a first connecting rod, one end of the first connecting rod is rotatably connected to a second connecting rod, and one end of the second connecting rod is rotatably connected to the bottom of the threaded sleeve.

[0013] The advantages of this utility model are:
[0014] 1. This utility model places the steel strip on the slide table, and the second motor of the clamping and limiting mechanism drives the sliders on both sides to slide towards each other. The sliders drive the guide posts to retract inward in the guide groove through the guide rod. The four guide posts on both sides retract inward so that the steel strip is parallel to the slide table. At this time, the hydraulic cylinder on the support frame pushes the pressure plate down, and the steel strip can be stably fixed. This achieves the effect of automatic positioning of the steel strip and reducing positioning errors, and solves the problem of excessive manual operation and easy positioning errors in the steel strip positioning process.
[0015] 2. In this utility model, after the steel strip is compressed by the lower pressure plate, the first motor of the double sliding mechanism drives the double threaded rod to rotate. The double threaded rod drives the sliding tables on both sides to move towards each other through the threaded sleeve, thereby aligning the steel strip shearing cuts on both sides. At this time, the steel strip can be welded, achieving the effect of automatic alignment of the steel strip shearing cuts, further saving labor and reducing errors. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.
[0024] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.
[0025] This application discloses a positioning structure for an automatic steel strip shearing and welding machine. (Refer to...) Figures 1-5A positioning structure for an automatic steel strip shearing and welding machine includes a fixed frame 1, with sliding tables 2 slidably connected to both sides of the inner cavity of the fixed frame 1. A double sliding mechanism 3 is movably installed at the bottom of the sliding tables 2. A through groove 21 is opened on one side of the sliding table 2, and a clamping and limiting mechanism 4 is movably installed inside the through groove 21. A support frame 5 is fixedly connected to the top of the sliding table 2, and a hydraulic cylinder 51 is fixedly installed on the top of the support frame 5. A pressure plate 52 is fixedly connected to the end of the telescopic shaft of the hydraulic cylinder 51. First, a steel strip is placed on the sliding tables 2 on both sides of the fixed frame 1, with the steel strip extending beyond the opposite side of the sliding table 2. The clamping and limiting mechanism 4 is used to make the steel strip horizontal with the sliding table 2, so that the steel strips on both sides are aligned on the same horizontal line. Then, the hydraulic cylinder 51 on the support frame 5 drives the pressure plate 52 to press down on the steel strip, so that the steel strip is stably restricted at the top of the sliding table 2. At this time, the steel strip is sheared. Then, the double sliding mechanism 3 is used to make the sliders 42 on both sides move towards each other, so that the sheared ends of the steel strips on both sides are aligned. Welding is then performed. This process improves the automation of steel strip shearing and welding.
[0026] The clamping and limiting mechanism 4 includes a second motor 48, which is fixedly installed on the top of the inner cavity of the through groove 21. Slider blocks 42 are slidably installed on both sides of the through groove 21. The second motor 48 slides in cooperation with the sliders 42. A guide rod 43 is fixedly connected to the top of the slider 42, and guide posts 44 are fixedly connected to both ends of the top of the guide rod 43. A guide groove 45 is provided on the top of the slide table 2, and the guide posts 44 slide in cooperation with the guide groove 45. The double sliding mechanism 3 includes a first motor 31, which is fixedly installed on one side of the fixed frame 1. A double-threaded rod 32 is fixedly connected to the output end of motor 31. A threaded sleeve 33 is threadedly connected to the outer wall of the double-threaded rod 32. The threaded sleeve 33 is fixedly connected to the bottom of the slide table 2. The second motor 48 drives the slider 42 to slide. The slider 42 drives the guide post 44 to retract inward in the guide groove 45 through the guide rod 43, thereby achieving the purpose of clamping the steel strip inward. The first motor 31 drives the double-threaded rod 32 to rotate, and the threaded sleeves 33 on both sides move towards each other on the double-threaded rod 32, so that the slide tables 2 on both sides can move towards each other.
[0027] Reference Figure 3 and Figure 4 The output end of the second motor 48 is fixedly connected to a gear 47, and the opposite side of the slider 42 is fixedly connected to a rack 46. The gear 47 meshes with the rack 46. Both sides of the inner cavity of the through groove 21 are fixedly connected to a slide rod 41. The slider 42 is slidably connected to the top of the slide rod 41. The second motor 48 drives the gear 47 to rotate, the gear 47 drives the rack 46 to move, and the rack 46 drives the slider 42 to slide on the slide rod 41, so that the slider 42 can move stably.
[0028] Reference Figure 1 , Figure 2 and Figure 4A double-threaded rod 32 is rotatably mounted at the bottom of the fixed frame 1. A limit sleeve 34 is rotatably mounted in the middle of the outer wall of the double-threaded rod 32. The limit sleeve 34 is fixedly connected to the bottom of the fixed frame 1. Limit grooves 35 are continuously formed on the inner wall of the limit sleeve 34. A limit ring 36 is rotatably connected in the limit groove 35. The limit ring 36 is fixedly connected to the outer wall of the double-threaded rod 32. A first connecting rod 37 is rotatably connected to the bottom of the limit sleeve 34. A second connecting rod 38 is rotatably connected to one end of the first connecting rod 37. One end of the second connecting rod 38 is rotatably connected to the bottom of the threaded sleeve 33. A positioning rod 11 is fixedly connected to the inner cavity of the fixed frame 1. A slide table 2 is also present. The sliding connection is attached to the outer wall of the positioning rod 11. The cross-sections of both ends of the inner cavity of the fixing frame 1 and both ends of the slide table 2 are semi-circular. The double threaded rod 32 is driven to rotate by the first motor 31. The threaded sleeves 33 on both sides move towards each other on the double threaded rod 32, so that the slide table 2 can move towards each other. The double threaded rod 32 rotates in the inner cavity of the limiting groove 35. The limiting ring 36 follows the double threaded rod 32 and rotates in the limiting groove 35, so that the double threaded rod 32 rotates stably without moving. The movement of the threaded sleeves 33 on both sides under the cooperation of the first connecting rod 37 and the second connecting rod 38 can reduce the displacement error between the threaded sleeves 33.
[0029] Working principle: In use, steel strips are placed on the slide tables 2 on both sides, with the steel strips extending beyond the opposite sides of the slider 42. First, the clamping and limiting mechanism 4 in the through groove 21 is used for alignment. Then, the second motor 48 drives the gear 47 to rotate. The gear 47, through the rack 46, causes the slider 42 to slide on the slide rod 41. The slider 42, through the guide rod 43, causes the guide column 44 to retract inward within the guide groove 45, clamping both sides of the steel strip, making the steel strip horizontal with the slide table 2. The hydraulic cylinder 51 on the support frame 5 then drives the pressure plate 52 to press down on the steel strip, restricting its displacement. At this point, the steel strip is sheared to make the ends flush. The double sliding mechanism 3 is used to make the shearing cuts of the steel strips on both sides make stable contact. The first motor 31 drives the double threaded rod 32 to rotate. The threaded sleeves 33 on both sides move towards each other on the double threaded rod 32 and drive the slide table 2 to slide towards each other in the inner cavity of the fixed frame 1. The slide table 2 slides stably on the positioning rod 11. The double threaded rod 32 rotates in the limiting groove 35 and drives the limiting ring 36 to rotate in the limiting groove 35, so that the double threaded rod 32 will not move horizontally when it rotates. The first connecting rod 37 and the second connecting rod 38 at the bottom of the limiting sleeve 34 cooperate to reduce the error of the movement of the threaded sleeves 33 on both sides. After the shearing cuts of the steel strip are aligned, welding is performed.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
