Description

Technical Field

[0001] This utility model belongs to the field of steel portable cans, and specifically relates to an adaptable steel portable can body welding device. Background Technology

[0002] A steel carrying can, simply put, is a portable metal container used for the safe storage and transfer of small amounts of oil (most commonly gasoline). Steel carrying cans are made of steel and are usually treated to prevent rust (such as galvanizing or painting). Steel is sturdy, impact-resistant, and effectively prevents static electricity buildup, making it safer than plastic containers.

[0003] The main structure of a steel portable can includes a main body with an oil nozzle and a handle. The main body consists of two symmetrical half-cans, each made of stamped sheet metal. Each half-can has an opening on its opposite side, and the two half-cans are welded together. The welding process requires clamps to hold the can in place before laser welding. However, the problem is that steel portable cans come in various sizes, and ordinary welding positioning devices cannot secure and weld cans of different sizes simultaneously. Utility Model Content

[0004] The purpose of this invention is to provide an adaptable steel portable can welding device that can fix and weld cans of different sizes, making it more adaptable and convenient to use.

[0005] The purpose of this utility model is achieved as follows: an adaptable steel portable can welding device includes a base, on which two symmetrical support plates are vertically arranged. A movable positioning box is connected to the support plate via a guide mechanism. A drive mechanism is provided on the support plate corresponding to the movable positioning box. A central positioning mechanism is provided in the middle of the movable positioning box. The central positioning mechanism includes a positioning rod movably connected to the movable positioning box. The end of the positioning rod is provided with a positioning head. A side positioning component is provided on the outer periphery of the movable positioning box. The movable positioning boxes on the two support plates are arranged symmetrically on the left and right.

[0006] In operation, this invention involves placing two semi-tank bodies to be welded into two movable positioning boxes. The positioning heads then hold the semi-tank bodies in place. Next, the positioning bolts around the movable positioning boxes are adjusted to tighten and secure the semi-tank bodies, ensuring that any two adjacent positioning bolts on either side of the two movable positioning boxes are at the same height. A drive cylinder then moves the movable positioning boxes outwards, merging the two semi-tank bodies together. A laser welding head then welds and secures the edges of the semi-tank bodies. After welding, the positioning bolts are loosened, and the cylinder separates the two movable positioning boxes, allowing the welded and secured complete tank body to be removed. Compared to existing technologies, this invention offers the advantages of being able to secure and weld tanks of different sizes, providing greater adaptability and ease of use.

[0007] As a further improvement of this utility model, the movable positioning box is rectangular, and both movable positioning boxes have openings on opposite sides.

[0008] As a further improvement of this utility model, the guiding mechanism includes four guide rods horizontally arranged on the side of the movable positioning box. The four guide rods form a rectangle, and the guide rods are perpendicular to the support base plate. Each guide rod extends outward through the corresponding support base plate and is movably connected to the support base plate. A limiting plate is provided at the end of the guide rod. When the cylinder drives the movable positioning box to move, the guide rods guide its movement.

[0009] As a further improvement of this utility model, the driving mechanism includes a driving cylinder that is horizontally mounted on the support plate, and the piston rod of the driving cylinder passes through the support plate and is connected to the corresponding moving positioning box in a transmission manner.

A limiting step three is provided at the end of the small-diameter rod located inside the movable positioning box. A spring is sleeved around the outer periphery of the small-diameter rod, with both ends of the spring elastically abutting against limiting step one and the movable positioning box, respectively. Limiting step three abuts against the inner wall of the movable positioning box. An installation rod is coaxially provided at the inward-facing end of the small-diameter rod. The positioning head is located at the front end of the installation rod and is made of magnetic material. The positioning head is used to attract and fix the half-tank body, and then the positioning bolts around the movable positioning box are used to press and fix the half-tank body to be welded.

[0011] As a further improvement of this utility model, each of the mobile positioning boxes contains a rectangular half-can body to be welded. The half-can bodies have openings on opposite sides of both half-can bodies within the two mobile positioning boxes, with one side extending out of the mobile positioning box. A positioning hole matching the positioning head is formed in the center of the other side of each half-can body. The positioning head is inserted into the corresponding positioning hole of the half-can body to be welded, positioning the half-can body and welding the two symmetrical half-can bodies together to form a complete steel carrying can.

[0012] As a further improvement of this utility model, the side positioning component includes four positioning bolts that are threaded around the movable positioning box.
