Description

Technical Field

[0001] The utility model relates to the field of vacuum cleaner parts production, in particular to a vacuum cleaner iron barrel welding device. Background Art

[0002] Industrial vacuum cleaners are a kind of environmentally friendly cleaning equipment commonly used in industry. They are used to collect waste, filter and purify air, and clean dust and particles in the environment during industrial production. Industrial vacuum cleaners are widely used in various fields such as textiles, chemicals, machinery, medicine, and casting. They include dust collection barrels, motors and fans that generate airflow, cloth-based bag-type separation and filtration devices, power switches, and power cords with plugs, etc. The motor and fan generate a vacuum, and the dust-laden air enters the dust collection barrel through the dust collection pipe and flows to the bag-type separation and filtration device, where most of the dust can be separated from the airflow and fall into the dust collection barrel.

[0003] Currently, the collection barrel is made of an iron barrel and needs to be welded into an iron barrel by iron sheets. However, in the existing iron barrel welding, it is inconvenient to fix the curled iron sheets to be welded, resulting in a decrease in welding quality.

[0004] Therefore, in order to solve the deficiencies in the prior art, a vacuum cleaner iron barrel welding device with a simple structure needs to be designed. Utility Model Content

[0005] The utility model provides a vacuum cleaner iron barrel welding device to solve the problems of the prior art.

[0006] The purpose of the utility model can be achieved through the following technical solutions: A vacuum cleaner iron barrel welding device comprises: an inner support assembly, an outer guide assembly and a welding assembly, the inner support assembly comprises a turntable and at least two groups of support members, the support members comprise an inner guide wheel, a slide rod and a guide sleeve, the inner guide wheel is arranged on the outside of the slide rod, the slide rod is elastically slidably arranged in the guide sleeve, at least two groups of circular protrusions 1 are arranged on the outside of the turntable, and a circular protrusion 2 matching the circular protrusion 1 is arranged on the inside of the slide rod, the welding assembly is arranged below the inner support assembly and facing the weld, the outer guide assembly comprises at least two groups of outer guide wheels and a guide wheel frame, the outer guide wheel is rotatably arranged on the guide wheel frame and is arranged in contact with the arc surface of the steel sheet, a driving motor is connected to the upper outer guide wheel, and a cylinder is arranged on the upper guide wheel frame.

[0007] As a further improvement, the support members are arranged in three groups at 120 degree annular intervals.

[0008] As a further improvement, a spring sleeved on the slide rod is provided inside the guide sleeve, and a pushing portion located below the spring is provided on the slide rod.

[0009] As a further improvement, the outer guide wheels and guide wheel frames are provided in four groups, and the guide wheel frames of the upper two groups are connected to the cylinders via connecting frames.

[0010] Compared with the prior art, the vacuum cleaner iron barrel welding device of the utility model has the following beneficial effects:

[0011] After the annular iron sheet is sent between the inner support component and the outer guide component, the cylinder drives the guide wheel frame to move downward, so that the upper outer guide wheel is tightly fitted with the arc surface of the outer wall of the patch, and the driving motor drives the outer guide wheel and then drives the iron sheet to move forward. At the same time, the internal turntable rotates so that the circular protrusion 2 contacts and squeezes the circular protrusion 1 on the inner side of the slide rod, so that the slide rod moves outward in the guide sleeve, so that the inner guide wheel supports the inner wall of the iron sheet. Through the internal and external cooperation of the inner support component and the outer guide component, the iron sheet is tensioned during the welding process, so that the welding assembly can stabilize the weld and improve the welding quality.
