Description

Technical Field

[0001] The utility model relates to the technical field of welding fixtures, in particular to a welding fixture for a gas storage cylinder. Background Art

[0002] The air cylinder is a gas storage device in the automobile braking system. The air cylinder is used to store the gas compressed by the air compressor (air pump) and is used in automobile braking, whistle and other systems. Most common air cylinders have the functions of energy storage, filtering, voltage stabilization and cooling. There are many places where gas is used on trucks, from whistles to brakes. If there is no air cylinder, the amount of gas pumped out by the air compressor alone is far from enough. At this time, the air pumped out by the air compressor needs to be stored in the air cylinder first, waiting for use at the critical moment. Just like a small stream in the mountain stream is not enough to drive the generator set, and it can only be driven after accumulating in the reservoir.

[0003] The existing gas cylinder welding fixture may overheat inside the device during use. The temperature of the gas cylinder will not drop after welding, and the next step cannot be carried out. This is not only inefficient and easily reduces the life of the device, but also workers may rashly touch the gas cylinder when they are not sure whether the surface temperature of the gas cylinder has dropped, resulting in burns. In addition, conventional welding fixtures will emit toxic gases during the welding process, which is harmful to the health of the workers. The molten welding particles dripping during the welding process will also accumulate inside the device and affect the operation of the device. Utility Model Content

[0004] The purpose of the utility model is to provide a welding fixture for a gas cylinder to solve the problems proposed in the above background technology that the continuous operation device causes internal overheating, reduces the life of the device, the natural cooling of the gas cylinder is too slow, which easily causes burns to the staff and makes it impossible to proceed to the next step in time, and the conventional welding fixture emits toxic gases during the welding process and molten welding particles accumulate inside the device, affecting the operation of the device.
