Description

Oil tank welding device

Technical Field

The patent of the utility model relates to a welding set technical field especially relates to an oil tank welding set.

Background

The oil tank is a container for containing fuel, is a special container for storing hydraulic oil or hydraulic fluid in a hydraulic system, can be divided into an open oil tank and a closed oil tank, and has enough large volume; the tank needs to be welded during the production process.

However, the existing welding device is inconvenient to move, cannot rotate the welding table, reduces the welding efficiency, cannot place a welding shield, a welding rod and the like used in the welding process, and is easy to lose. In the technical field of existing welding, manual welding is generally adopted, the manual welding efficiency is low, and the risk of scalding workers exists. In addition, for large-scale products which need to be welded at multiple positions, the existing welding mode cannot achieve good welding effect. For example, in the formation of a fuel tank for a vehicle, the fuel tank generally includes an upper tank shell, a lower tank shell, a pump flange, etc., and in the formation of the whole fuel tank, the welding formation between the upper tank shell and the lower tank shell by spot welding is the most important process, and the welding quality directly affects the overall quality of the formed fuel tank. Then in the process of spot welding and connecting the upper shell and the lower shell, after the upper shell and the lower shell are positioned by a clamp, the clamp and the shell of the oil tank are rotated and moved to a welding position by holding the oil tank, a welding switch of a spot welding machine is stepped by a foot, an upper electrode and a lower electrode of the spot welding machine are pressed and electrified, a one-time spot welding process of the upper shell and the lower shell of the oil tank is completed, and after the steps are repeated for multiple times, the welding operation of the oil tank is completed.

When an oil tank workpiece is welded, the difficulty mainly comprises two aspects, one is that the upper shell and the lower shell of the oil tank workpiece need to be subjected to spot welding at a plurality of positions, and the consistency of welding positions is poor when workers operate; secondly, the production beat is slower, and the work efficiency is lower, therefore, the inventor of the present invention has conducted an in-depth study on the above problems, and how to improve the welding success rate and improve the work efficiency is generated by the present invention.

The oil strainer can effectively prevent sundries from entering other equipment through the oil outlet pipe.

The oil tank inside advance oil pipe and go out and be equipped with the oil interceptor between the oil pipe, the oil in the oil tank does not use for a long time and can deposit, the oil interceptor prevents that the impact that produces when the oil inlet oil feed from influencing the oil quality of the lumen of producing oil, ensures that the oil quality of going out the oil pipe is not influenced.

The horizontal connecting rod and the welding gun are attached to the end face of the oil tank, and the nozzle on the welding gun is aligned to the connecting seam on the other side edge between the iron sheet and the oil tank after the horizontal connecting rod rotates for 90 degrees.

The side of the oil tank is provided with a liquid level meter which can display the height of the liquid level in the oil tank in real time.

From the above embodiment, it can be easily seen that the utility model has the following advantages:

1. the utility model provides an oil tank welding set, simple structure, the accessible rotates the connecting rod, adjusts the relative position of welding set and oil tank to be favorable to welding the oil tank.

2. Through the cooperation of driving motor and welder, can realize treating the automatic weld of welding the oil tank, the effectual welding efficiency that has improved has ensured the welded uniformity.
