[0021] Furthermore, the processing method of the welding device for manufacturing a steel cylinder is characterized by comprising the following steps:

[0022] S1: When the welding device is used, the steel cylinder is placed on the surface of the lifting frame, and then the motor is used to drive the two conical cylinders to approach each other. The conical cylinder can pass through the two ends of the steel cylinder to squeeze and fix the bottle body through its own shape. After the steel cylinder is fixed, it can be welded through the welding frame. When the steel cylinder is fixed through the conical cylinder, the output end of the motor can drive the extension rod to rotate. When the extension rod rotates, it can drive the small gear to rotate. When the small gear rotates, it can drive the large gear to mesh and rotate. When the large gear meshes and rotates, it can rotate through the bearing. When the large gear rotates, it can drive the rotating block on the top to rotate. When the rotating block rotates, it can pull the two rotating rods at the same time, and the rotating rods are pulled When the cylinder is in motion, the guide block can be driven to move by the connecting block, and the guide block can slide through the guide groove when it moves. When the guide block slides, the rotating rod can rotate through the connecting block and the rotating block. At the same time, the guide block can drive the movable block to move. When the movable block moves, it can drive the conical cylinder to move to both ends of the cylinder for squeezing and fixing. The stability of the cylinder fixation can be improved by increasing the squeezing force. After the cylinder is fixed, the bottle body can be manually rotated. After the cylinder is subjected to the rotational force, the cylinder can rotate on the inner side of the movable block through the bearing, thereby realizing the change of direction, improving the stability of the welding device for the cylinder fixation, and the fixing efficiency, and improving the quality of the device welding the cylinder in disguised form;

[0023] S2: Steel cylinders are large and small. After steel cylinders of different specifications are placed on the surface of the lifting frame, they are not aligned with the center of the conical cylinder. At this time, the L-shaped block is pulled up. When the L-shaped block is pulled up, the two engaging grooves can be driven to move. When the engaging groove moves to the inclined surface of the engaging block, it can be squeezed. When the engaging block is squeezed, it can slide with the first telescopic groove through the engaging groove. When the engaging block slides, it can squeeze the spring inside the first telescopic groove. After the engaging block is squeezed out of the engaging groove, the L-shaped block can slide through the sliding groove. When the L-shaped block slides, it can drive the second bevel gear to move upward. When the second bevel gear moves upward, it can drive the pinion gear to move upward. When the pinion gear moves upward, it can drive the extension rod to extend. When the second bevel gear extends to the side of the first bevel gear, a meshing connection can be achieved. At this time, the L-shaped block can drive another engaging groove to move to the side of the engaging block. The engaging block can be reset by the elastic force of the spring itself. When the engaging block is reset, it can be engaged with the engaging groove for positioning. When the L-shaped block is positioned, it can drive the second bevel gear to be positioned. At this time, the motor is started, and the output end of the motor can drive the pinion to rotate through the extension rod. When the pinion rotates, it can drive the second bevel gear to rotate. When the second bevel gear rotates, it can improve stability through the L-shaped block. When the second bevel gear rotates, it can mesh and drive the first bevel gear to rotate. When the first bevel gear rotates, it can drive the double-headed bevel gear rod to rotate. When the double-headed bevel gear rod rotates, it can rotate through the second rotating groove. When the double-headed bevel gear rod rotates, it can drive the third bevel gear to mesh and rotate. When the third bevel gear meshes and rotates, it can drive the threaded block to rotate. When the threaded block rotates, it can drive the lifting frame to slide through the thread. When the lifting frame slides through the thread, it can slide through the fixed block. When the lifting frame slides, its own height can be adjusted, thereby driving the surface cylinder to rise or fall, so that the center position of the cylinder and the center position of the conical tube can maintain the same horizontal position, further improving the effect of the welding device on fixing the cylinder, facilitating the welding device to weld cylinders of different specifications, and improving the adaptability of the welding device;

[0024] S3: When the welding device fixes the steel cylinder, it is necessary to adjust the steel cylinder to the specified position first. In order to improve the accuracy of the adjustment, first press the push block to drive the telescopic block to move. When the telescopic block moves, it can slide through the second telescopic slot. When the telescopic block slides, it can squeeze the spring inside the second telescopic slot. After the telescopic block is squeezed into the second telescopic slot, the visual sensor is moved. When the visual sensor moves, the bottom slot can be moved to the top of the pillar for insertion. When the visual sensor is inserted, it can drive the positioning slot to move, and then rotate the positioning slot to the side of the telescopic block. Release the push block to drive the telescopic block to reset under the action of the spring. When the telescopic block is reset, it can be inserted into the positioning slot for engagement and positioning. When the positioning slot is positioned, it can drive the visual sensor to be installed on the surface of the pillar. After the visual sensor is installed, the position of the steel cylinder and the cone can be measured by vision. According to the measurement structure, the lifting frame will be driven to rise or fall to the specified height, which improves the convenience of using the device and the welding efficiency. In addition, the welding quality of the welding device can be monitored by the visual sensor.

[0025] Compared with the prior art, the present invention has the following beneficial effects:

[0026] 1. The welding device and processing method for manufacturing steel cylinders drive the small gear to mesh and rotate through the motor, thereby driving the two conical cylinders to move to the two ends of the steel cylinder for extrusion and fixation, thereby improving the stability and fixing efficiency of the welding device for fixing the steel cylinder. Secondly, by pulling the L-shaped block, the second bevel gear can drive the first bevel gear to rotate, thereby adjusting the height of the lifting frame, making it convenient for the welding device to weld steel cylinders of different specifications, thereby improving the adaptability of the welding device;

[0027] 2. A large gear and a small gear are provided. The large gear and the small gear can increase the torque through the difference in gear ratio and tooth size, thereby improving the stability of the cone tube in squeezing and fixing the cylinder;

[0028] 3. A rotating block is provided, through which the two rotating rods can be pulled to move at the same time, realizing the synchronous movement of the two conical cylinders, and further improving the stability of the welding device fixing the cylinder;
