Detailed ways

Exemplary embodiments embodying the features and advantages of the present invention will be described in detail in the following description. It should be understood that the present invention can have various changes in different embodiments without departing from the scope of the present invention, and the descriptions and drawings therein are essentially used for illustration rather than limitation this invention.

Referring to Fig. 1, the present invention first provides a method for assembling a tank container, the method comprising:

S00: A roller frame is provided to support the barrel of the can container, and a chuck is provided to hold the head of the can container on both ends of the barrel. Among them, the roller frame supports the cylinder horizontally on it, and in order to adapt to the tank containers of different specifications, the roller frame can be set as an adjustable structure. The chuck is located on the outer side of the two ends of the roller frame, so that the head is located at the two ends of the cylinder, and the chuck can use the claws to hold the head.

S10: When the chuck is at the feeding position, place the head on the chuck and make the chuck hold the head; when the head is held by the chuck, the central axis of the head coincides with the axis of the chuck. Preferably, the feeding position is a horizontal position. At this time, the axis of the chuck is in a vertical state. Correspondingly, the head can be placed on the chuck in a horizontal state, which is convenient for the loading device to hoist the head and reduce labor. And driving operation, reduce labor intensity and improve work efficiency.

S20: Turn the chuck to the working position, so that the head is opposite to the cylinder supported on the roller frame; the working position is the vertical position, at this time, the head is in the vertical position, and the center axis of the head will be in the center of the cylinder Axes coincide.

S30: make the head and the cylinder butt, and make the chuck hold the head and the cylinder at the same time after the docking; in this step, preferably, the head is close to the cylinder by moving the chuck in the direction close to the roller frame Until the two are butted, after the head and the cylinder are butted, the head and the cylinder are fixed and clamped together by the claws on the chuck. If some of the cylinder sections on the cylinder are out-of-round deformation before the head and the cylinder are butted, the out-of-round cylinder can be rounded first, and then the head can be butted with the rounded cylinder.

S40: Rotate the chuck to drive the head and the cylinder to rotate, and weld the butt seam between the head and the cylinder. In this step, the head and the cylinder are rotated around their central axis.

In this method, the roller frame and the chuck are the basis for the implementation of the method, and the cylinder body and the head are held by the roller frame and the chuck, so as to facilitate the butt assembly of the two, and then the head is connected to the head through the operations of steps S10 to S40. The barrel is spot welded.

Through this method, the welding operation position can be set to a certain fixed position outside the circumference of the butt joint of the cylinder body and the head, and when the part to be welded between the head and the cylinder is rotated to the welding operation position, the Weld the parts to be welded. After the head and the cylinder are fixed by the chuck, the parts that need to be welded on the entire circumference of the butt joint between the head and the cylinder can be welded to the welding position in turn within a 360-degree rotation cycle to complete the welding, thereby improving the production efficiency; During the entire welding operation, the operator does not need to change the working position or perform climbing operations, which reduces labor intensity.
