Its main functions are to enhance the overall rigidity of the frame, ensure the coaxiality accuracy of the wall panel holes, and serve as the installation reference for other components.
[0003] As a connecting reinforcement component, the printing press tie beam is a fixed-length connector, which means it cannot be adjusted according to the distance between the transmission wall panel and the operating wall panel of the printing press, resulting in poor installation adaptability. Therefore, we propose an adjustable printing press tie beam to solve this defect of the prior art. Utility Model Content
[0004] To address the shortcomings of existing technologies, this invention provides an adjustable printing press tie beam.
[0005] To achieve the above objectives, this utility model provides the following technical solution: an adjustable printing press pull beam, including a pull beam rod, a pre-drilled hole in the middle of the pull beam rod, connecting seats sliding at both ends of the pull beam rod, connecting rods passing through the pull beam rod on opposite sides of the connecting seats, the connecting rods being located within the pre-drilled hole, and an adjustment limiting component being provided between the connecting rods and the pull beam rod, the adjustment limiting component being used for adjusting the movement of the connecting rods and limiting their position after adjustment.
[0006] By adopting the above technical solution, the connecting rod in the reserved hole is moved to drive the connecting seat to move in the tie beam rod, and the locking and fixing after the movement adjustment is achieved in conjunction with the adjustment limit component.
[0007] As a preferred technical solution of this utility model, the adjusting and limiting assembly includes a vertical rod vertically disposed on the upper end of the connecting rod and a pair of locking seats disposed on the upper end of the pull beam rod. The vertical rod is provided with a threaded rod on the outside, the threaded rod passes through the locking seat, and the threaded rod is externally threaded to a locking nut that contacts the surface of the locking seat.
[0008] By using the above technical solution, the locking nut is screwed in by rotating the tool, which causes the threaded rod to move and drive the vertical rod, connecting rod and connecting seat to move synchronously, thereby realizing the adjustment of the combined length of the tie beam rod and connecting seat and the limit after adjustment.
[0009] As a preferred embodiment of this utility model, the locking seat is provided with a through hole for the threaded rod to pass through, and the through hole has the same diameter as the threaded rod.
[0010] By adopting the above technical solution, the through hole on the locking seat achieves stability in limiting the movement of the threaded rod.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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 protection scope of the present utility model.
[0025] Please see Figures 1 to 5 The adjustable printing press pull beam in this embodiment mainly consists of core components such as pull beam rod 1, connecting seat 3, and adjustment limiting component. By setting a reserved hole 2 in the middle of the pull beam rod 1, sliding connecting seat 3 at both ends, and using the adjustment limiting component to realize the movement adjustment and limiting of the connecting seat 3, the distance between the printing press transmission surface wall plate and the operating surface wall plate can be flexibly adjusted to improve installation adaptability.
[0026] The tie rod 1 is a long, rod-shaped structure made of high-strength alloy steel. It has good mechanical strength and resistance to deformation, which ensures that it can stably enhance the overall rigidity of the frame and ensure the coaxiality accuracy of the wall panel holes during the operation of the printing press, and serves as the installation reference for other components.
[0027] The tie rod 1 is horizontally set, and a reserved hole 2 is opened through the middle of its upper and lower surfaces. The reserved hole 2 is a rectangular through hole, which provides space for the movement of the connecting rod 4. The front and rear side walls of the inner cavity of the tie rod 1 are fixed with racks 10. The racks 10 are located in the reserved hole 2. The racks 10 have uniform tooth pitch and standard tooth shape, which are used to cooperate with the meshing rack 13 to realize the locking function.
[0028] The connecting seat 3 is a rectangular block structure, made of high-strength alloy steel of the same material as the tie beam rod 1 to ensure the stability of the connection. Each connecting seat 3 has a connecting rod 4 on its opposite side. The connecting rod 4 is a rectangular block structure and is fixedly connected to the connecting seat 3 by welding to ensure the connection strength.
[0029] Two connecting seats 3 are slidably disposed inside the two ends of the tie beam rod 1, and the connecting rod 4 passes through the tie beam rod 1 and is located in the reserved hole 2. It can slide freely in the reserved hole 2 along the length direction of the tie beam rod 1, thereby realizing the position adjustment of the connecting seat 3 on the tie beam rod 1.
[0030] An adjustment limit assembly is provided between the connecting rod 4 and the tie beam 1. The adjustment limit assembly is used for the movement adjustment of the connecting rod 4 and the limit after adjustment.
[0031] First implementation method (threaded rod 7 mates with locking nut 8):
[0032] The adjusting limit assembly includes a vertical rod 5 fixed to the upper surface of the connecting rod 4, a pair of locking seats 6 fixed to the upper surface of the tie beam 1, a threaded rod 7 fixed to the outside of the vertical rod 5, and a locking nut 8 threadedly connected to the outside of the threaded rod 7 and in contact with the surface of the locking seat 6. The vertical rod 5 is a cylindrical rod structure, located between the two locking seats 6, and vertically fixed to the connecting rod 4 by welding. The locking seat 6 is a rectangular block structure, fixedly set at the upper end of the tie beam 1. Each locking seat 6 has a through hole for the threaded rod 7 to pass through. The through hole has the same diameter as the threaded rod 7 to ensure the stability of the threaded rod 7 moving within the through hole. The threaded rod 7 is a cylindrical threaded rod, fixedly connected to the vertical rod 5 by welding. The locking nut 8 is a standard hexagonal nut, made of high-strength alloy steel, with sufficient strength and wear resistance.
[0033] The vertical rod 5 is vertically set at the upper end of the connecting rod 4, and the threaded rod 7 is horizontally set outside the vertical rod 5 and passes through the through hole on the locking seat 6. The locking nut 8 is threadedly connected to the outside of the threaded rod 7 and is in close contact with the surface of the locking seat 6. By rotating the locking nut 8, the threaded rod 7 can be moved, thereby driving the vertical rod 5, the connecting rod 4 and the connecting seat 3 to move synchronously, realizing the adjustment of the combined length of the tie beam rod 1 and the connecting seat 3. After the adjustment is completed, the limit is achieved by the friction between the locking nut 8 and the locking seat 6.
[0034] Second embodiment (rack 10 engages with meshing rack 13):
[0035] A pair of hollow cylinders 9, arranged opposite to each other, are fixed to the outside of the vertical rod 5. The hollow cylinders 9 are cylindrical structures and are fixedly connected to the vertical rod 5 by welding. A stainless steel spring 11 is fixed inside the hollow cylinder 9. The stainless steel spring 11 is made of high-quality stainless steel and has good elasticity and corrosion resistance. One end of the stainless steel spring 11 is fixedly connected to the bottom of the hollow cylinder 9, and the other end is fixed to a moving rod 12 that slides against the inner wall of the hollow cylinder 9. The moving rod 12 is a cylindrical rod structure that can slide freely along the axial direction inside the hollow cylinder 9. The other end of the moving rod 12 is fixed to a meshing rack 13 that meshes with the rack 10. The tooth pitch of the meshing rack 13 matches the tooth pitch of the rack 10 to ensure accurate meshing. A lever 14 is vertically fixed to the outside of the moving rod 12. The lever 14 is a cylindrical rod structure and is fixedly connected to the moving rod 12 by welding for easy manual operation.
[0036] Hollow cylinders 9 are symmetrically arranged outside the vertical rod 5. Stainless steel springs 11 are located inside the hollow cylinders 9. Moving rods 12 are sleeved inside the stainless steel springs 11 and can slide inside the hollow cylinders 9. Engaging racks 13 are fixedly arranged at the end of the moving rods 12 away from the stainless steel springs 11, corresponding to the racks 10 on the inner wall of the tie rod 1. A lever 14 is vertically arranged outside the moving rods 12 for easy manual operation. When the stainless steel springs 11 are in their natural state, the engaging racks 13 engage with the racks 10 to lock and fix the vertical rod 5, connecting rod 4, and connecting seat 3. When the stainless steel springs 11 are in a compressed state, the engaging racks 13 and racks 10 separate, allowing the position of the connecting seat 3 to be adjusted.
[0037] Working principle and usage steps:
[0038] Preparations before adjustment
[0039] Before using the adjustable printing press pull beam, check that all parts are intact and undamaged. Ensure that the pull beam rod 1, connecting seat 3, adjusting limit assembly, and other parts are free from cracks, deformation, or other defects. At the same time, prepare the necessary tools, such as wrenches.
[0040] Adjust the position of connector 3.
[0041] When adjusting using the first embodiment: Place the wrench on the locking nut 8 and rotate the locking nut 8 clockwise or counterclockwise according to the required adjustment direction. Since the locking nut 8 is threadedly connected to the threaded rod 7, and the threaded rod 7 is fixedly connected to the connecting rod 4 through the vertical rod 5, rotating the locking nut 8 will cause the threaded rod 7 to move, thereby driving the vertical rod 5, the connecting rod 4, and the connecting seat 3 to move synchronously. During the adjustment process, observe the position of the connecting seat 3 and make it adapt to the position of the printing press drive surface wall plate and the operating surface wall plate. After the adjustment is completed, stop rotating the locking nut 8. At this time, the friction between the locking nut 8 and the locking seat 6 will fix the connecting seat 3 in the current position, realizing the limit after adjustment.
[0042] When adjusting using the second embodiment: Hold the lever 14 by hand and move it towards the vertical rod 5, causing the moving rod 12 to move inside the hollow cylinder 9, compressing the stainless steel spring 11. As the moving rod 12 moves, the meshing rack 13 separates from the rack 10. At this time, the connecting seat 3 can slide freely on the pull beam rod 1. According to the direction of adjustment, push the connecting seat 3 to move on the pull beam rod 1 so that the connecting seat 3 reaches the appropriate position. After the adjustment is completed, release the lever 14. The stainless steel spring 11 extends and resets under the elastic action, pushing the moving rod 12 to move in the opposite direction inside the hollow cylinder 9, so that the meshing rack 13 re-meets the rack 10, thereby locking and fixing the moved vertical rod 5, connecting rod 4 and connecting seat 3 to prevent movement after adjustment.
[0043] Installation and use,
[0044] Install the adjusted printing press tie beam between the transmission and operation panels of the printing press. Connect and fix it to other components through the mounting holes on the connecting seat 3. After installation, check whether each connection is firm to ensure that the printing press tie beam can function properly, enhance the overall rigidity of the frame, ensure the coaxiality accuracy of the wall panel holes, and serve as the installation reference for other components.
[0045] The first and second embodiments can work together to ensure the stability of the connecting seat 3 after it is moved and adjusted, and improve the connection strength between the connecting seat 3 and the tie rod 1.
[0046] In summary, this adjustable printing press tie beam, through its reasonable structural design and multiple adjustment methods, enables flexible adjustment based on the distance between the printing press drive side wall panel and the operating side wall panel, thus improving installation adaptability.
