Description

Technical Field

[0001] The utility model belongs to the field of portable cans, and in particular relates to a tank body and oil nozzle welding device. Background Art

[0002] Steel tote tanks are primarily used to store and transport various liquid or semi-liquid substances. Steel tote tanks are commonly used to hold liquids such as gasoline, diesel, kerosene, and lubricating oil. Steel tote tanks feature handles for easy portability and mobility, making them more convenient for transport and handling.

[0003] The structure of a steel portable tank consists of a tank body and a fuel nozzle, which are fixed by welding. However, there are the following problems when welding the two: the tank body and the fuel nozzle need to be positioned when welding. Since the tank body itself is hollow and the fuel nozzle is also a hollow sleeve-shaped workpiece, the hollow tank body and the fuel nozzle are easily damaged when fixed with a clamp. Utility Model Content

[0004] The utility model aims to provide a tank body and oil nozzle welding device, which can firmly position the tank body and the oil nozzle, facilitate welding and fixing the tank body and the oil nozzle, and improve the assembly efficiency of the tank body and the oil nozzle.

[0006] During operation, before welding the tank body and the oil nozzle, the limiting sleeve is placed on the rotating shaft and each outward expansion strut. The welding holes of the oil nozzle and the tank body are then placed on each outward expansion strut in sequence, so that the welding holes of the oil nozzle and the tank body are aligned. The limiting sleeve is then pushed backward, causing each outward expansion strut to expand outward and tighten the welding holes of the oil nozzle and the tank body. The rotating shaft then rotates, driving the oil nozzle and the tank body to rotate, and the laser is used to weld and fix the outer periphery of the welding holes of the oil nozzle and the tank body. Compared with the existing technology, the beneficial effect of the present invention is that it can firmly position the tank body and the oil nozzle, facilitate welding and fixing the tank body and the oil nozzle, and improve the assembly efficiency of the tank body and the oil nozzle.

[0007] As a further improvement of the present invention, four connecting seats are evenly distributed along the circumference, and the connecting seat includes two left-right symmetrical seat bodies. The rear end of the outward support rod is provided with a connecting plate extending between the two seat bodies, and the connecting plate is rotatably connected to the two seat bodies through the distribution shaft.

[0008] As a further improvement of the present invention, the outwardly extending support rods are arc-shaped and arranged to correspond to the outer circumference of the rotating shaft. Each outwardly extending support rod is arranged through the sleeve-shaped oil nozzle and extends into the welding hole of the tank body. The outwardly extending support rods support and fix the tank body and the oil nozzle.

[0009] As a further improvement of the present invention, the elastic expansion mechanism includes four fixed plates evenly distributed along the circumference of the rotating shaft, each fixed plate corresponding to each expansion support rod, and a tension spring is installed between each expansion support rod and the corresponding fixed plate. The tension spring provides tension to the expansion support rod.

[0010] As a further improvement of the present invention, the rear end of the limiting sleeve is provided with an outer step, and the front end of the rotating shaft and the rear end of each outward expansion strut extend into the limiting sleeve. The limiting sleeve is movably connected to the rotating shaft and each outward expansion strut. The outer step is pushed by a driving rod to facilitate the forward and backward adjustment of the position of the limiting sleeve.

[0011] As a further improvement of the present invention, the rotary drive mechanism includes a mounting base provided on a side of the base, a reduction motor being mounted on the mounting base via a bracket, the output shaft of the reduction motor being parallel to the rotating shaft, a transmission sprocket being sleeved on the rear end of the rotating shaft, the output shaft of the reduction motor being provided with a driving sprocket, the driving sprocket being connected to the transmission sprocket via a chain, and the reduction motor driving the rotating shaft to rotate via the sprocket.

The rotating drive mechanism includes a mounting seat 12 provided on the side of the base 1, a reduction motor 14 mounted on the mounting seat 12 via a bracket 13, the output shaft of the reduction motor 14 being parallel to the rotating shaft 3, a transmission sprocket 15 provided at the rear end of the rotating shaft 3, the output shaft of the reduction motor 14 being provided with a driving sprocket 16, the driving sprocket 16 being connected to the transmission sprocket 15 via a chain 17. The reduction motor 14 drives the rotating shaft 3 to rotate via the sprocket.

[0019] Four coupling seats 4 are evenly spaced along the circumference. They comprise two symmetrical bases 4a. A coupling plate 5a extends between the two bases 4a at the rear end of an outward-facing strut 5. The coupling plate 5a is pivotally connected to the two bases 4a via a pin 7. The outward-facing struts 5 are arc-shaped and aligned with the outer circumference of the rotating shaft 3. Each strut 5 extends through a sleeve-shaped oil nozzle 8 and into a weld hole 9a in the tank body 9. The outward-facing struts 5 support and secure the tank body 9 and the oil nozzle 8.

[0020] The elastic outward expansion mechanism includes four fixed plates 10 uniformly distributed along the circumference of the rotating shaft 3. Each fixed plate 10 is provided with a one-to-one correspondence with each outward expansion support rod 5. A tension spring 11 is provided between each outward expansion support rod 5 and the corresponding fixed plate 10. The tension spring 11 provides tension to the outward expansion support rod 5.

[0021] The rear end of the limiting sleeve 6 is provided with an outer step 6a, and the front end of the rotating shaft 3 and the rear end of each outward expansion strut 5 are all extended into the limiting sleeve 6. The limiting sleeve 6 is movably connected to the rotating shaft 3 and each outward expansion strut 5. The outer step 6a is pushed by the driving rod to facilitate the forward and backward adjustment of the position of the limiting sleeve 6.

[0022] During operation of the present invention, before welding the tank body 9 and the oil nozzle 8, the limiting sleeve 6 is placed on the rotating shaft 3 and each outward expansion strut 5. Then, the welding holes 9a of the oil nozzle 8 and the tank body 9 are placed on each outward expansion strut 5 in sequence, so that the welding holes 9a of the oil nozzle 8 and the tank body 9 fit together. The limiting sleeve 6 is then pushed backward, causing each outward expansion strut 5 to expand outward and tighten the welding holes 9a of the oil nozzle 8 and the tank body 9. The rotating shaft 3 is then rotated to drive the oil nozzle 8 and the tank body 9 to rotate, and the laser is used to weld and fix the outer periphery of the welding holes 9a of the oil nozzle 8 and the tank body 9.
