Description

Technical Field

[0001] The utility model relates to steel cylinder processing equipment, in particular to a tailstock angle adjustment device for a spiral welding machine. Background Art

[0002] Currently, large-scale construction projects often involve the use of water, gas, and oil pipelines. To prevent leaks, copper cylinders (also known as inner molds) are increasingly favored. The cylinder is manufactured by spirally coiling a steel strip around a core mold and welding it. One end of the core mold is suspended on a flange, while the other end is supported by a tailstock and rotates with the axis.

[0003] The applicant filed an application on April 26, 2024, titled "Internal Mold Welding and Forming Device," with application number 202322625493.5. The application discloses that as the core mold rotates, the unwinding rack unwinds the steel strip, allowing it to be wound around the core mold. Simultaneously, a welding robot on a gantry performs the welding operation. During unwinding, the unwinding cart moves, simultaneously driving the welding robot along with the gantry. This improves efficiency, saves manpower, and reduces costs.

[0004] Since the unwinding frame (i.e. the tailstock of the spiral welding machine) has a single specification, it can only adapt to the processing of inner molds of a single size. When replacing inner molds of different specifications, it is inconvenient to adjust the angle and the adaptability is poor. Utility Model Content

[0005] In view of the above problems, the utility model provides a spiral welding machine tailstock angle adjustment device with simple structure, convenient adjustment and improved adaptability.

[0006] The technical solution of the utility model is: a spiral welding machine tailstock angle adjustment device comprises a plate placing vehicle and an unwinding frame, wherein the unwinding frame is provided with a steel strip;

[0007] It also includes an adjustment mechanism, which is connected between the unwinding vehicle and the unwinding frame, and includes a tail beam, a front adjustment beam and an adjustment frame.

[0008] The adjustment frame is installed on the top of the tail beam and the front adjustment beam.

[0009] A rotation center axis is provided in the middle of the tail crossbeam, a rotation seat is provided on the adjustment frame, and the rotation center axis is located in the rotation seat;

[0010] The front end adjustment beam is connected to the pallet truck by lifting.

[0011] The unwinding rack is used to be placed on the adjusting rack.

[0012] A horizontal push rod mechanism is provided on the front end adjustment beam, and the horizontal push rod mechanism is used for pushing and pulling the adjustment frame.

[0013] The horizontal push rod mechanism is a hydraulic cylinder, an air cylinder or a horizontally arranged worm gear elevator.

[0014] The front end adjustment beam is connected to the pallet truck through a worm gear elevator.

[0015] The front end adjustment beam is connected to the pallet truck via a hydraulic cylinder or an air cylinder.

[0016] It also includes a pair of parallel slide rails, and pulleys are arranged around the bottom of the pallet trolley.

[0017] The pulley is used to be connected to the slide rail.

[0018] During operation, the utility model provides an adjustment mechanism between the unloading cart and the unwinding frame, facilitating adjustment of the unwinding frame's position, thereby driving the adjustment of the steel strip's position to accommodate the production and processing of inner molds of varying specifications. When the adjustment mechanism is in operation, the front-end adjustment beam is raised and lowered, thereby driving the unwinding frame on the adjustment frame to rise and fall; the horizontal push rod mechanism is actuated, thereby driving the adjustment frame to move, thereby adapting to the processing position requirements.

[0019] The utility model is convenient to process and reliable to operate. BRIEF DESCRIPTION OF THE DRAWINGS
