Description

Technical Field

[0001] This utility model relates to the field of printing press wall panel technology, specifically to a printing press wall panel welding positioning table. Background Technology

[0002] The printing press wall panels are the walls on both sides of the printing cylinder and ink roller on the machine. Their function is to support and fix them. They are one of the main components of the printing press. Their design, processing and assembly directly affect the accuracy and printing performance of the entire printing press, and have a significant impact on the stability and reliability of the printing press. Good wall panel design, processing and correct and efficient assembly methods will play an important role in ensuring the performance and safety of the printing press and improving its lifespan.

[0003] When welding printing press wall panels, the panels are manually positioned and their horizontal position and distance are adjusted before a connecting frame is erected between them for welding. However, manual positioning is inefficient and labor-intensive, and it is also prone to causing the welded wall panels to shift, affecting the accuracy of subsequent assembly and welding. Therefore, we propose a welding positioning table for printing press wall panels to solve this technical defect. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a welding positioning table for printing press wall panels.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a printing press wall panel welding positioning table, comprising a pair of support frames and a pair of plate positioning seats, wherein the opposite surfaces of the plate positioning seats are open, and hydraulic push rods are provided on the left and right opposing surfaces of the plate positioning seats, wherein a push plate is provided at the push rod of the hydraulic push rods and located inside the plate positioning seats, and hydraulic push rods are provided on the front and rear sides of the plate positioning seats, wherein clamping plates are provided at the push rods of the hydraulic push rods and located inside the plate positioning seats, wherein symmetrically distributed directional sliding rods are provided between the opposite sides of the support frames, and a pair of sliding seats slide between the directional sliding rods;

[0006] The upper end of the sliding seat is provided with a hydraulic push rod three, and the push rod of the hydraulic push rod three is provided with a lifting seat that passes through the sliding seat and is connected to the upper end of the plate positioning seat;

[0007] The support frames are provided with drive components that enable the sliding seats to move in opposite directions.

[0008] Using the above technical solution, the plate positioning seat on the lifting seat is moved up and down by the hydraulic push rod three, so that when the plate positioning seat moves to the top, the wall panel is placed vertically on the ground, so that the panel is located below the cavity of the plate positioning seat. The plate positioning seat is then moved down and fitted onto the outside of the panel. After the panel is fitted, the push plate is moved by the hydraulic push rod one, so that the panel fits against the inner wall of the opening side of the plate positioning seat. At the same time, the clamping plate is moved by the hydraulic push rod two to clamp the panel in the center, thereby ensuring that the two panels are set opposite each other and are perpendicular to the ground.

[0009] After the plates are fixed, the positioning seats of the plates are moved upward by the hydraulic push rod three working adjustment, so that the fixed plates are lifted off the ground. This makes it easier to drive the sliding seat to move on the directional slide rod by the drive component, thereby adjusting the distance between the plates fixed on the positioning seats. After ensuring that a pair of plates are horizontal and vertical and the distance is adjusted, it is easy to build and weld the connecting frame between the plates.

[0010] As a preferred embodiment of this utility model, the plate positioning seat is perpendicular to the bottom of the support frame.

[0011] By adopting the above technical solution, the horizontal and vertical effects of the wall panel fixed in the panel positioning seat are guaranteed.

[0012] As a preferred technical solution of this utility model, the driving component includes a servo motor located on the right side of the support frame. The output shaft of the servo motor is provided with a bidirectional threaded rod that passes through the sliding seat and is connected to the support frame on the left side for rotation. The bidirectional threaded rod is provided with a forward thread groove and a reverse thread groove on the outer left and right sides of the middle part, respectively. A threaded cylinder connected to the sliding seat is threaded in both the forward thread groove and the reverse thread groove.

[0013] Using the above technical solution, the servo motor drives the bidirectional threaded rod to rotate. By utilizing the forward and reverse threaded grooves on the bidirectional threaded rod and their threaded connection with the threaded cylinder, the sliding seat is driven to slide directionally outside the directional slide rod.

[0014] As a preferred embodiment of this utility model, the left end of the bidirectional threaded rod has a movable seat that rotates, and the movable seat is connected to the support frame.

[0015] The above technical solution facilitates the smooth rotation of the bidirectional threaded rod on the movable seat.

[0016] As a preferred technical solution of this utility model, the upper surface of the directional slide rod is provided with a scale through which the sliding seat passes, and the front and rear sides of the opposite surface of the sliding seat are provided with indicator blocks that fit against the surface of the scale.

[0017] By adopting the above technical solution, it is convenient to move the indicator block on the scale by moving the sliding seat, and determine the distance between the plates after the movement and adjustment by the distance between the indicator scales.

[0018] As a preferred embodiment of this utility model, the end face of the indicator block and the sliding seat at the opposite end is aligned with the inner wall of the opening of the plate positioning seat.

[0019] By adopting the above technical solution, the distance between the scales indicated on the end face of the indicator block is equal to the distance between the fixed plates inside the plate positioning seat.

[0020] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0021] The wall panel welding positioning table of this printing press uses hydraulic push rod three to push the plate positioning seat on the lifting seat to move up and down, ensuring that when the plate positioning seat moves to the top, the wall panel is placed vertically on the ground, so that the panel is located below the cavity of the plate positioning seat. The plate positioning seat moves down and fits onto the outside of the panel. After the fit is completed, hydraulic push rod one pushes the push plate to move, so that the panel fits against the inner wall of the opening side of the plate positioning seat. At the same time, hydraulic push rod two pushes the clamping plate to move and clamp the panel in the center, thus ensuring that the two panels are set opposite each other and are perpendicular to the ground.

[0022] After the plates are fixed, the hydraulic push rod adjusts the plate positioning seat upwards, causing the fixed plates to lift off the ground. This allows the drive assembly to move the sliding seat on the directional slide rod, thereby adjusting the distance between the plates fixed on the plate positioning seat. After ensuring that a pair of plates are horizontal and vertical and the distance is adjusted, it is easy to build and weld the connecting frame between the plates. Compared with the existing technology, this avoids the time-consuming, labor-intensive, and inefficient manual positioning, which is prone to the problem of the plates not being positioned vertically and horizontally, thus affecting the accuracy of subsequent assembly and welding.
